For your information
Please note that this manual applies to all models and explains all equipment,
including options. Therefore, you may find some explanations for equipment
not installed on your vehicle.
All specifications provided in this manual are current at the time of printing.
However, because of the Toyota policy of continual product improvement, we
reserve the right to make changes at any time without notice.
Depending on specifications, the vehicle shown in the illustrations may differ
from your vehicle in terms of equipment.
Approximately five hours after the hybrid system is turned off, you may hear
sound coming from under the vehicle for several minutes. This is the sound of
a fuel evaporation leakage check and, it does not indicate a malfunction.
A wide variety of non-genuine spare parts and accessories for Toyota vehi-
cles are currently available in the market. You should know that Toyota does
not warrant these products and is not responsible for their performance,
repair, or replacement, or for any damage they may cause to, or adverse
effect they may have on, your Toyota vehicle.
This vehicle should not be modified with non-genuine Toyota products. Modi-
fication with non-genuine Toyota products could affect its performance, safety
or durability, and may even violate governmental regulations. In addition,
damage or performance problems resulting from the modification may not be
covered under warranty.

The installation of a mobile two-way radio system in your vehicle could affect
electronic systems such as:
● Hybrid system
● Multiport fuel injection system/sequential multiport fuel injection system
● Toyota Safety Sense P
● Anti-lock brake system
● SRS airbag system
● Seat belt pretensioner system
Be sure to check with your Toyota dealer for precautionary measures or spe-
cial instructions regarding installation of a mobile two-way radio system.
High voltage parts and cables on the hybrid vehicles emit approximately the
same amount of electromagnetic waves as the conventional gasoline pow-
ered vehicles or home electronic appliances despite of their electromagnetic
shielding.
Unwanted noise may occur in the reception of the mobile two-way radio.

The vehicle is equipped with sophisticated computers that will record certain
data, such as:
The recorded data varies according to the vehicle grade level and options
with which it is equipped
These computers do not record conversations or sounds, and only record
images outside of the vehicle in certain situations.
• Engine speed/Electric motor speed (traction motor speed)
• Accelerator status
• Brake status
• Vehicle speed
• Operation status of the driving assist systems, such as the ABS and pre-
collision system
• Images from the camera (available only when certain safety systems are
activated, which varies depending on the vehicle specifications).
• Hybrid battery (traction battery) status
● Data Transmission
Your vehicle may transmit the data recorded in these computers to Toyota
without notification to you.
● Data usage
Toyota may use the data recorded in these computers to diagnose malfunc-
tions, conduct research and development, and improve quality.
Toyota will not disclose the recorded data to a third party except:
• With the consent of the vehicle owner or with the consent of the lessee if
the vehicle is leased
• In response to an official request by the police, a court of law or a govern-
ment agency
• For use by Toyota in a lawsuit.
• For research purposes where the data is not tied to a specific vehicle or
vehicle owner
● Recorded image information can be erased by your Toyota dealer.
The image recording function can be disabled. However, if the function is
disabled, data from when the pre-collision system operates will not be avail-
able.

This vehicle is equipped with an event data recorder (EDR). The main pur-
pose of an EDR is to record, in certain crash or near crash-like situations,
such as an air bag deployment or hitting a road obstacle, data that will assist
in understanding how a vehicle’s systems performed. The EDR is designed to
record data related to vehicle dynamics and safety systems for a short period
of time, typically 30 seconds or less.
The EDR in this vehicle is designed to record such data as:
• How various systems in your vehicle were operating;
• Whether or not the driver and passenger safety belts were buckled/fas-
tened;
• How far (if at all) the driver was depressing the accelerator and/or brake
pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better understanding of the circumstances in
which crashes and injuries occur.
NOTE: EDR data are recorded by your vehicle only if a non-trivial crash situ-
ation occurs; no data are recorded by the EDR under normal driving condi-
tions and no personal data (e.g., name, gender, age, and crash location) are
recorded. However, other parties, such as law enforcement, could combine
the EDR data with the type of personally identifying data routinely acquired
during a crash investigation.
To read data recorded by an EDR, special equipment is required, and access
to the vehicle or the EDR is needed. In addition to the vehicle manufacturer,
other parties, such as law enforcement, that have the special equipment, can
read the information if they have access to the vehicle or the EDR.
● Disclosure of the EDR data
Toyota will not disclose the data recorded in an EDR to a third party except
when:
• An agreement from the vehicle’s owner (or the lessee for a leased vehi-
cle) is obtained
• In response to an official request by the police, a court of law or a govern-
ment agency
• For use by Toyota in a lawsuit
However, if necessary, Toyota may:
• Use the data for research on vehicle safety performance
• Disclose the data to a third party for research purposes without disclosing
information about the specific vehicle or vehicle owner

The SRS airbag and seat belt pretensioner devices in your Toyota contain
explosive chemicals. If the vehicle is scrapped with the airbags and seat belt
pretensioners left as they are, this may cause an accident such as fire. Be
sure to have the systems of the SRS airbag and seat belt pretensioner
removed and disposed of by a qualified service shop or by your Toyota dealer
before you scrap your vehicle.
Special handling may apply,
See www.dtsc.ca.gov/hazardouswaste/perchlorate.
Your vehicle has components that may contain perchlorate. These compo-
nents may include airbag, seat belt pretensioners, and wireless remote con-
trol batteries.

WARNING
■ General precautions while driving
Driving under the influence: Never drive your vehicle when under the influ-
ence of alcohol or drugs that have impaired your ability to operate your vehi-
cle. Alcohol and certain drugs delay reaction time, impair judgment and
reduce coordination, which could lead to an accident that could result in
death or serious injury.
Defensive driving: Always drive defensively. Anticipate mistakes that other
drivers or pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full attention to driving. Anything that
distracts the driver, such as adjusting controls, talking on a cellular phone or
reading can result in a collision with resulting death or serious injury to you,
your occupants or others.
■ General precaution regarding children’s safety
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral.
There is also a danger that children may injure themselves by playing with
the windows, or other features of the vehicle. In addition, heat build-up or
extremely cold temperatures inside the vehicle can be fatal to children.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
● Do not adjust the position of the driver’s seat while driving.
Doing so could cause the driver to lose control of the vehicle.
● Do not place a cushion between the driver or passenger and the seatback.
A cushion may prevent correct posture from being achieved, and reduce
the effectiveness of the seat belt and head restraint.
● Do not place anything under the front seats.
Objects placed under the front seats may become jammed in the seat
tracks and stop the seat from locking in place. This may lead to an acci-
dent and the adjustment mechanism may also be damaged.
● Always observe the legal speed limit when driving on public roads.
● When driving over long distances, take regular breaks before you start to
feel tired.
Also, if you feel tired or sleepy while driving, do not force yourself to con-
tinue driving and take a break immediately.

The pretensioners help the seat
belts to quickly restrain the occu-
pants by retracting the seat belts
when the vehicle is subjected to
certain types of severe frontal or
side collision or a vehicle rollover.
The pretensioners do not activate
in the event of a minor frontal
impact, a minor side impact or a
rear impact.
■ Emergency locking retractor (ELR)
The retractor will lock the belt during a sudden stop or on impact. It may also
lock if you lean forward too quickly. A slow, easy motion will allow the belt to
extend so that you can move around fully.
■ Automatic locking retractor (ALR)
When a passenger’s shoulder belt is completely extended and then retracted
even slightly, the belt is locked in that position and cannot be extended. This
feature is used to hold the child restraint system (CRS) firmly. To free the belt
again, fully retract the belt and then pull the belt out once more.

■ Child seat belt usage
The seat belts of your vehicle were principally designed for persons of adult
size.
● Use a child restraint system appropriate for the child, until the child
becomes large enough to properly wear the vehicle’s seat belt. (P. 58)
● When the child becomes large enough to properly wear the vehicle’s seat
belt, follow the instructions regarding seat belt usage. (P. 30)
■ Replacing the belt after the pretensioner has been activated
If the vehicle is involved in multiple collisions, the pretensioner will activate for
the first collision, but will not activate for the second or subsequent collisions.
■ Seat belt extender
If your seat belts cannot be fastened
securely because they are not long
enough, a personalized seat belt extender
is available from your Toyota dealer free
of charge.
WARNING
Observe the following precautions to reduce the risk of injury in the event of
sudden braking, sudden swerving or an accident.
Failing to do so may cause death or serious injury.
■ Wearing a seat belt
● Ensure that all passengers wear a seat belt.
● Always wear a seat belt properly.
● Each seat belt should be used by one person only. Do not use a seat belt
for more than one person at once, including children.
● Toyota recommends that children be seated in the rear seat and always
use a seat belt and/or an appropriate child restraint system.
● To achieve a proper seating position, do not recline the seat more than
necessary. The seat belt is most effective when the occupants are sitting
up straight and well back in the seats.
● Do not wear the shoulder belt under your arm.
● Always wear your seat belt low and snug across your hips.

WARNING
■ Pregnant women
■ People suffering illness
Obtain medical advice and wear the seat belt in the proper way. (P. 30)
■ When children are in the vehicle
P. 69
■ Seat belt pretensioners
● Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents the sensor
from detecting the passenger’s weight properly. As a result, the seat belt
pretensioner for the front passenger’s seat may not activate in the event of
a collision.
● If the pretensioner has activated, the SRS warning light will come on. In
that case, the seat belt cannot be used again and must be replaced at
your Toyota dealer.
Obtain medical advice and wear the seat
belt in the proper way. (P. 30)
Women who are pregnant should posi-
tion the lap belt as low as possible over
the hips in the same manner as other
occupants, extending the shoulder belt
completely over the shoulder and avoid-
ing belt contact with the rounding of the
abdominal area.
If the seat belt is not worn properly, not
only the pregnant woman, but also the
fetus could suffer death or serious injury
as a result of sudden braking or a colli-
sion.

WARNING
■ Adjustable shoulder anchor
Always make sure the shoulder belt is positioned across the center of your
shoulder. The belt should be kept away from your neck, but not falling off
your shoulder. Failure to do so could reduce the amount of protection in an
accident and cause death or serious injuries in the event of a sudden stop,
sudden swerve or accident. (P. 31)
■ Seat belt damage and wear
● Do not damage the seat belts by allowing the belt, plate, or buckle to be
jammed in the door.
● Inspect the seat belt system periodically. Check for cuts, fraying, and loose
parts. Do not use a damaged seat belt until it is replaced. Damaged seat
belts cannot protect an occupant from death or serious injury.
● Ensure that the belt and plate are locked and the belt is not twisted.
If the seat belt does not function correctly, immediately contact your Toyota
dealer.
● Replace the seat assembly, including the belts, if your vehicle has been
involved in a serious accident, even if there is no obvious damage.
● Do not attempt to install, remove, modify, disassemble or dispose of the
seat belts. Have any necessary repairs carried out by your Toyota dealer.
Inappropriate handling may lead to incorrect operation.
■ Using a seat belt extender
● Do not wear the seat belt extender if you can fasten the seat belt without
the extender.
● Do not use the seat belt extender when installing a child restraint system
because the belt will not securely hold the child restraint system, increas-
ing the risk of death or serious injury in the event of an accident.
● The personalized extender may not be safe on another vehicle, when
used by another person, or at a different seating position other than the
one originally intended.

Your vehicle is equipped with ADVANCED AIRBAGS designed based
on the US motor vehicle safety standards (FMVSS208). The airbag
sensor assembly (ECU) controls airbag deployment based on infor-
mation obtained from the sensors etc. shown in the system compo-
nents diagram above. This information includes crash severity and
occupant information. As the airbags deploy, a chemical reaction in
the inflators quickly fills the airbags with non-toxic gas to help restrain
the motion of the occupants.

WARNING
■ SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury.
● The driver and all passengers in the vehicle must wear their seat belts
properly.
The SRS airbags are supplemental devices to be used with the seat belts.
● The SRS driver airbag deploys with considerable force, and can cause
death or serious injury especially if the driver is very close to the airbag.
The National Highway Traffic Safety Administration (NHTSA) advises:
Since the risk zone for the driver’s airbag is the first 2 - 3 in. (50 - 75 mm)
of inflation, placing yourself 10 in. (250 mm) from your driver airbag pro-
vides you with a clear margin of safety. This distance is measured from
the center of the steering wheel to your breastbone. If you sit less than 10
in. (250 mm) away now, you can change your driving position in several
ways:
• Move your seat to the rear as far as you can while still reaching the ped-
als comfortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many drivers can achieve the 10 in.
(250 mm) distance, even with the driver seat all the way forward, simply
by reclining the back of the seat somewhat. If reclining the back of your
seat makes it hard to see the road, raise yourself by using a firm, non-
slippery cushion, or raise the seat if your vehicle has that feature.
• If your steering wheel is adjustable, tilt it downward. This points the air-
bag toward your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA above, while
still maintaining control of the foot pedals, steering wheel, and your view
of the instrument panel controls.

PRIUS PRIME_OM_OM47C77U_(U)
WARNING
■ SRS airbag precautions
● The SRS front passenger airbag also deploys with considerable force, and
can cause death or serious injury especially if the front passenger is very
close to the airbag. The front passenger seat should be as far from the air-
bag as possible with the seatback adjusted, so the front passenger sits
upright.
● Improperly seated and/or restrained infants and children can be killed or
seriously injured by a deploying airbag. An infant or child who is too small
to use a seat belt should be properly secured using a child restraint sys-
tem. Toyota strongly recommends that all infants and children be placed in
the rear seats of the vehicle and properly restrained. The rear seats are
safer for infants and children than the front passenger seat. (P. 58)
● If the seat belt extender has been con-
nected to the front seat belt buckles but
the seat belt extender has not also been
fastened to the latch plate of the seat
belt, the SRS front airbags will judge
that the driver and front passenger are
wearing the seat belt even though the
seat belt has not been connected. In
this case, the SRS front airbags may
not activate correctly in a collision,
resulting in death or serious injury in the
event of a collision. Be sure to wear the
seat belt with the seat belt extender.

WARNING
■ SRS airbag precautions
● Do not sit on the edge of the seat or
lean against the dashboard.
● Do not allow a child to stand in front of
the SRS front passenger airbag unit or
sit on the knees of a front passenger.
● Do not allow the front seat occupants to
hold items on their knees.
● Do not lean against the door, the roof
side rail or the front, side and rear pil-
lars.
● Do not allow anyone to kneel on the
passenger seat toward the door or put
their head or hands outside the vehicle.

WARNING
■ SRS airbag precautions
● Do not hang coat hangers or other hard objects on the coat hooks. All of
these items could become projectiles and may cause death or serious
injury, should the SRS curtain shield airbags deploy.
● If a vinyl cover is put on the area where the SRS knee airbag will deploy,
be sure to remove it.
● Do not use seat accessories which cover the parts where the SRS side
airbags and SRS seat cushion airbag inflate as they may interfere with
inflation of the SRS airbags. Such accessories may prevent the side air-
bags and seat cushion airbag from activating correctly, disable the system
or cause the side airbags and seat cushion airbag to inflate accidentally,
resulting in death or serious injury.
● Do not strike or apply significant levels of force to the area of the SRS air-
bag components or the front doors.
Doing so can cause the SRS airbags to malfunction.
● Do not touch any of the component parts immediately after the SRS air-
bags have deployed (inflated) as they may be hot.
● Do not attach anything to or lean any-
thing against areas such as the dash-
board, steering wheel pad and lower
portion of the instrument panel.
These items can become projectiles
when the SRS driver, front passenger
and knee airbags deploy.
● Do not attach anything to areas such as
a door, windshield, side windows, front
or rear pillar, roof side rail and assist
grip.

door or side window to allow fresh air in, or leave the vehicle if it is safe to
do so. Wash off any residue as soon as possible to prevent skin irritation.
● If the areas where the SRS airbags are stored, such as the steering wheel
pad and front and rear pillar garnishes, are damaged or cracked, have
them replaced by your Toyota dealer.
● Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents the sensor
from detecting the passenger’s weight properly. As a result, the SRS front
airbags for the front passenger may not deploy in the event of a collision.
■ Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications
without consulting your Toyota dealer. The SRS airbags may malfunction or
deploy (inflate) accidentally, causing death or serious injury.
● Installation, removal, disassembly and repair of the SRS airbags
● Repairs, modifications, removal or replacement of the steering wheel,
instrument panel, dashboard, seats or seat upholstery, front, side and rear
pillars, roof side rails, front door panels, front door trims or front door
speakers
● Modifications to the front door panel (such as making a hole in it)
● Repairs or modifications of the front fender, front bumper, or side of the
occupant compartment
● Installation of a grille guard (bull bars, kangaroo bar, etc.), snow plows,
winches or roof luggage carrier
● Modifications to the vehicle’s suspension system
● Installation of electronic devices such as mobile two-way radios and CD
players
● Modifications to your vehicle for a person with a physical disability

■ If the SRS airbags deploy (inflate)
● Slight abrasions, burns, bruising etc., may be sustained from SRS airbags,
due to the extremely high speed deployment (inflation) by hot gases.
● A loud noise and white powder will be emitted.
● Parts of the airbag module (steering wheel hub, airbag cover and inflator) as
well as the front seats, parts of the front and rear pillars, and roof side rails,
may be hot for several minutes. The airbag itself may also be hot.
● The windshield may crack.
● The hybrid system will be stopped and fuel supply to the engine will be
stopped. (P. 99)
● The emergency flashers will turn on automatically. (P. 652)
● For Safety Connect subscribers, if any of the following situations occur, the
system is designed to send an emergency call to the response center, noti-
fying them of the vehicle’s location (without needing to push the “SOS” but-
ton) and an agent will attempt to speak with the occupants to ascertain the
level of emergency and assistance required. If the occupants are unable to
communicate, the agent automatically treats the call as an emergency and
helps to dispatch the necessary emergency services. (P. 76)
• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe rear-end collision.
■ SRS airbag deployment conditions (SRS front airbags)
● The SRS front airbags will deploy in the event of an impact that exceeds the
set threshold level (the level of force corresponding to an approximately 12 -
18 mph [20 - 30 km/h] frontal collision with a fixed wall that does not move or
deform).
However, this threshold velocity will be considerably higher in the following
situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole,
which can move or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a
truck
● Depending on the type of collision, it is possible that only the seat belt pre-
tensioners and seat cushion airbag will activate.
● The SRS front airbags for the front passenger will not activate if there is no
passenger sitting in the front passenger seat. However, the SRS front air-
bags for the front passenger may deploy if luggage is put in the seat, even if
the seat is unoccupied.
● The SRS seat cushion airbag on the front passenger seat will not operate if
the occupant is not wearing a seat belt.

■ SRS airbag deployment conditions (SRS side and curtain shield airbags)
● The SRS side and curtain shield airbags will deploy in the event of an
impact that exceeds the set threshold level (the level of force corresponding
to the impact force produced by an approximately 3300 lb. [1500 kg] vehicle
colliding with the vehicle cabin from a direction perpendicular to the vehicle
orientation at an approximate speed of 12 - 18 mph [20 - 30 km/h]).
● Both SRS curtain shield airbags will deploy in the event of vehicle rollover.
● Both SRS curtain shield airbags may also deploy in the event of a severe
frontal collision.
■ Conditions under which the SRS airbags may deploy (inflate), other than
a collision
The SRS front airbags and SRS curtain shield airbags may also deploy if a
serious impact occurs to the underside of your vehicle. Some examples are
shown in the illustration.
The SRS curtain shield airbags may also deploy under the situations shown
in the illustration.
● Hitting a curb, edge of pavement or hard
surface
● Falling into or jumping over a deep hole
● Landing hard or falling
● The angle of vehicle tip-up is marginal.
● The vehicle skids and hits a curb stone.

■ Types of collisions that may not deploy the SRS airbags (SRS front air-
bags)
The SRS front airbags do not generally inflate if the vehicle is involved in a
side or rear collision, if it rolls over, or if it is involved in a low-speed frontal
collision. But, whenever a collision of any type causes sufficient forward
deceleration of the vehicle, deployment of the SRS front airbags may occur.
● Collision from the side
● Collision from the rear
● Vehicle rollover

■ Types of collisions that may not deploy the SRS airbags
(SRS side and curtain shield airbags)
The SRS side and curtain shield airbags may not activate if the vehicle is
subjected to a collision from the side at certain angles, or a collision to the
side of the vehicle body other than the passenger compartment.
The SRS side airbags do not generally inflate if the vehicle is involved in a
frontal or rear collision, if it rolls over, or if it is involved in a low-speed side
collision.
The SRS curtain shield airbags do not generally inflate if the vehicle is
involved in a rear collision, if it pitches end over end, or if it is involved in a
low-speed side or low-speed frontal collision.
● Collision from the side to the vehicle
body other than the passenger compart-
ment
● Collision from the side at an angle

WARNING
■ Front passenger occupant classification system precautions
Observe the following precautions regarding front passenger occupant clas-
sification system.
Failure to do so may cause death or serious injury.
● Wear the seat belt properly.
● Make sure the front passenger’s seat belt plate has not been left inserted
into the buckle before someone sits in the front passenger seat.
● Make sure the “AIR BAG OFF” indicator light is not illuminated when using
the seat belt extender for the front passenger seat. If the “AIR BAG OFF”
indicator light is illuminated, disconnect the extender tongue from the seat
belt buckle, and reconnect the seat belt. Reconnect the seat belt extender
after making sure the “AIR BAG ON” indicator light is illuminated. If you
use the seat belt extender while the “AIR BAG OFF” indicator light is illumi-
nated, the SRS airbags for the front passenger will not activate, which
could cause death or serious injury in the event of a collision.
● Do not apply a heavy load to the front passenger seat or equipment (e.g.
seatback pocket).
● Do not put weight on the front passenger seat by putting your hands or
feet on the front passenger seat seatback from the rear passenger seat.
● Do not let a rear passenger lift the front passenger seat with their feet or
press on the seatback with their legs.
● Do not put objects under the front passenger seat.
● Do not recline the front passenger seatback so far that it touches a rear
seat. This may cause the “AIR BAG OFF” indicator light to be illuminated,
which indicates that the SRS airbags for the front passenger will not acti-
vate in the event of a severe accident. If the seatback touches the rear
seat, return the seatback to a position where it does not touch the rear
seat. Keep the front passenger seatback as upright as possible when the
vehicle is moving. Reclining the seatback excessively may lessen the
effectiveness of the seat belt system.

WARNING
■ Front passenger occupant classification system precautions
● If an adult sits in the front passenger seat, the “AIR BAG ON” indicator
light is illuminated. If the “AIR BAG OFF” indicator is illuminated, ask the
passenger to sit up straight, well back in the seat, feet on the floor, and
with the seat belt worn correctly. If the “AIR BAG OFF” indicator still
remains illuminated, either ask the passenger to move to the rear seat, or
if that is not possible, move the front passenger seat fully rearward.
● When it is unavoidable to install a forward-facing child restraint system on
the front passenger seat, install the child restraint system on the front pas-
senger seat in the proper order. (P. 58)
● Do not modify or remove the front seats.
● Do not kick the front passenger seat or subject it to severe impact. Other-
wise, the SRS warning light may come on to indicate a malfunction of the
front passenger occupant classification system. In this case, contact your
Toyota dealer immediately.
● Child restraint systems installed on the rear seat should not contact the
front seatbacks.
● Do not use a seat accessory, such as a cushion and seat cover, that cov-
ers the seat cushion surface.
● Do not modify or replace the upholstery of the front seat.
● Adjust the front passenger seat so that the head restraint does not touch
the ceiling. If the head restraint is left in contact with the ceiling, the system
may not detect the front passenger properly, leading to improper operation
of the airbags.

Exhaust gas precautions
Harmful substance to the human body is included in exhaust
gases if inhaled.
WARNING
Exhaust gases include harmful carbon monoxide (CO), which is colorless and
odorless. Observe the following precautions.
Failure to do so may cause exhaust gases enter the vehicle and may lead to
an accident caused by light-headedness, or may lead to death or a serious
health hazard.
■ Important points while driving
● Keep the back door closed.
● If you smell exhaust gases in the vehicle even when the back door is
closed, open the side windows and have the vehicle inspected at your
Toyota dealer as soon as possible.
■ When parking
● If the vehicle is in a poorly ventilated area or a closed area, such as a
garage, stop the hybrid system.
● Do not leave the vehicle with the hybrid system on for a long time.
If such a situation cannot be avoided, park the vehicle in an open space
and ensure that exhaust fumes do not enter the vehicle interior.
● Do not leave the hybrid system operating in an area with snow build-up, or
where it is snowing. If snowbanks build up around the vehicle while the
hybrid system is operating, exhaust gases may collect and enter the vehi-
cle.
■ Exhaust pipe
The exhaust system needs to be checked periodically. If there is a hole or
crack caused by corrosion, damage to a joint or abnormal exhaust noise, be
sure to have the vehicle inspected and repaired by your Toyota dealer.

Riding with children
● It is recommended that children sit in the rear seats to avoid acci-
dental contact with the shift lever, wiper switch etc.
● Use the rear door child-protector lock or the window lock switch to
avoid children opening the door while driving or operating the
power window accidentally. (P. 282, 312)
● Do not let small children operate equipment which may catch or
pinch body parts, such as the power window, hood, back door,
seats etc.
Observe the following precautions when children are in the vehi-
cle.
Use a child restraint system appropriate for the child, until the
child becomes large enough to properly wear the vehicle’s seat
belt.
WARNING
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral.
There is also a danger that children may injure themselves by playing with
the side windows or other features of the vehicle. In addition, heat build-up
or extremely cold temperatures inside the vehicle can be fatal to children.

WARNING
■ When a child is riding
Observe the following precautions.
Failure to do so may result in death or serious injury.
● For effective protection in automobile accidents and sudden stops, a child
must be properly restrained, using a seat belt or child restraint system
which is correctly installed. For installation details, refer to the operation
manual enclosed with the child restraint system. General installation
instructions are provided in this manual.
● Toyota strongly urges the use of a proper child restraint system that con-
forms to the weight and size of the child, installed on the rear seat. Accord-
ing to accident statistics, the child is safer when properly restrained in the
rear seat than in the front seat.
● Holding a child in your or someone else’s arms is not a substitute for a
child restraint system. In an accident, the child can be crushed against the
windshield or between the holder and the interior of the vehicle.
■ Handling the child restraint system
If the child restraint system is not properly fixed in place, the child or other
passengers may be seriously injured or even killed in the event of sudden
braking, sudden swerving, or an accident.
● If the vehicle were to receive a strong impact from an accident, etc., it is
possible that the child restraint system has damage that is not readily visi-
ble. In such cases, do not reuse the restraint system.
● Make sure you have complied with all installation instructions provided
with the child restraint system manufacturer and that the system is prop-
erly secured.
● Keep the child restraint system properly secured on the seat even if it is
not in use. Do not store the child restraint system unsecured in the pas-
senger compartment.
● If it is necessary to detach the child restraint system, remove it from the
vehicle or store it securely in the luggage compartment.

WARNING
■ When using a child restraint system
Observe the following precautions.
Failure to do so may result in death or serious injury.
● Never install a rear-facing child restraint system on the front passenger
seat even if the “AIR BAG OFF” indicator light is illuminated. In the event
of an accident, the force of the rapid inflation of the front passenger airbag
can cause death or serious injury to the child if the rear-facing child
restraint system is installed on the front passenger seat.
● A forward-facing child restraint system may be installed on the front pas-
senger seat only when it is unavoidable. A child restraint system that
requires a top tether strap should not be used in the front passenger seat
since there is no top tether strap anchor for the front passenger seat.
● When a booster seat is installed, always ensure that the shoulder belt is
positioned across the center of the child’s shoulder. The belt should be
kept away from the child’s neck, but not so that it could fall off the child’s
shoulder.
● A forward-facing child restraint system
may be installed on the front passenger
seat only when it is unavoidable. When
installing a forward-facing child restraint
system on the front passenger seat,
move the seat as far back as possible,
even if the “AIR BAG OFF” indicator
light is illuminated.
If the head restraint interferes with the
child restraint system installation and
the head restraint can be removed,
remove the head restraint.
● Do not allow the child to lean his/her
head or any part of his/her body against
the door or the area of the seat, front or
rear pillars, or roof side rails from which
the SRS side airbags or SRS curtain
shield airbags deploy even if the child is
seated in the child restraint system. It is
dangerous if the SRS side airbags and
curtain shield airbags inflate, and the
impact could cause death or serious
injury to the child.

WARNING
■ When installing a child restraint system
Observe the following precautions.
Failure to do so may result in death or serious injury.
● Do not allow children to play with the seat belt. If the seat belt becomes
twisted around a child’s neck, it may lead to choking or other serious inju-
ries that could result in death.
If this occurs and the buckle cannot be unfastened, scissors should be
used to cut the belt.
● Ensure that the belt and plate are securely locked and the seat belt is not
twisted.
● Shake the child restraint system left and right, and forward and backward
to ensure that it has been securely installed.
● After securing a child restraint system, never adjust the seat.
● When a booster seat is installed, always ensure that the shoulder belt is
positioned across the center of the child’s shoulder. The belt should be
kept away from the child’s neck, but not so that it could fall off the child’s
shoulder.
● Follow all installation instructions provided by the child restraint system
manufacturer.
● When securing some types of child restraint systems in rear seats, it may
not be possible to properly use the seat belts in positions next to the child
restraint without interfering with it or affecting seat belt effectiveness. Be
sure your seat belt fits snugly across your shoulder and low on your hips. If
it does not, or if it interferes with the child restraint, move to a different
position. Failure to do so may result in death or serious injury.
■ When installing a booster seat
To prevent the belt from going into ALR lock mode, do not fully extend the
shoulder belt. ALR mode causes the belt to tighten only. This could cause
injury or discomfort to the child. (P. 31)
■ Do not use a seat belt extender
If a seat belt extender is used when installing a child restraint system, the
seat belt will not securely hold the child restraint system, which could cause
death or serious injury to the child or other passengers in the event of sud-
den braking, sudden swerving or an accident.

■ Exposure to radio frequency signals
The Safety Connect system installed in your vehicle is a low-power
radio transmitter and receiver. It receives and also sends out radio
frequency (RF) signals.
In August 1996, the Federal Communications Commission (FCC)
adopted RF exposure guidelines with safety levels for mobile wire-
less phones. Those guidelines are consistent with the safety stan-
dards previously set by the following U.S. and international
standards bodies.
● ANSI (American National Standards Institute) C95.1 [1992]
● NCRP (National Council on Radiation Protection and Measure-
ment) Report 86 [1986]
● ICNIRP (International Commission on Non-Ionizing Radiation
Protection) [1996]
Those standards were based on comprehensive and periodic eval-
uations of the relevant scientific literature. Over 120 scientists, engi-
neers, and physicians from universities, and government health
agencies and industries reviewed the available body of research to
develop the ANSI Standard (C95.1).
The design of Safety Connect complies with the FCC guidelines in
addition to those standards.

Gasoline engine
Electric motor (traction motor)
The plug-in hybrid system is a system excellent in both econom-
ical efficiency of electric vehicles and practicality of hybrid vehi-
cles.
● EV driving can be performed using electricity charged from an
external power source.
*
● If the amount of electricity remaining in the hybrid battery (traction
battery) becomes low, the vehicle is automatically controlled in
such a way that it can be driven as a hybrid vehicle through the
joint use of the gasoline engine.
*: The EV driving range will vary in accordance with conditions such as
vehicle speed, the amount of charge remaining in the hybrid battery
(traction battery) and the usage of the air conditioning system. The gaso-
line engine may also be used simultaneously in accordance with driving
conditions.

operation mode will be switched to HV mode.
The hybrid battery (traction battery) charge mode will be canceled by
pressing EV/HV mode selection switch or EV auto mode switch.
*: The maximum charge amount in the hybrid battery (traction battery)
charge mode is approximately 80% of the fully charged capacity for the
charging from an external power source.
■ If the plug-in hybrid system operation mode cannot be changed
In the following situations, the plug-in hybrid system operation mode cannot
be changed even if the EV/HV mode selection switch or EV auto mode switch
is pressed. (In this case, the warning message is displayed on the multi-infor-
mation display when the switch is pressed.)
● When electricity needed for EV driving is not remaining (when in EV/EV
auto mode)
● When the traction battery is almost completely charged (hybrid battery [trac-
tion battery] charge mode)
■ When switching from EV mode to another mode using the switch
When the power switch is turned off, operation mode switching is canceled
and the system returns to EV mode the next time the vehicle is started.
■ Hybrid battery (traction battery) charge mode
● The following may occur to protect the system, etc.
• Cannot switch to hybrid battery (traction battery) charge mode or cannot
cancel it
• Gasoline engine does not start or stops even after switching to hybrid bat-
tery (traction battery) charge mode
● If a load to the system is large, such as when the power consumption of the
air conditioning system is large or when the temperature of the engine cool-
ant is high, it may take longer time than usual to charge using the hybrid bat-
tery (traction battery) charge mode, or charging to the hybrid battery
(traction battery) may not be performed.

PRIUS PRIME_OM_OM47C77U_(U)
2-1. Plug-in hybrid system
■ When in EV/EV auto mode
In EV/EV auto mode, EV driving (driving using only the electric
motor)
* is possible. However, depending on the situation, EV driv-
ing may be canceled and both gasoline engine and electric motor
are used (P. 95). Also, if a little electricity is remaining in the
hybrid battery (traction battery), HV mode is automatically selected.
To drive in EV/EV auto mode long, observe the followings.
● Avoid sudden acceleration and sudden deceleration, and be sure
to drive smoothly.
If you repeatedly accelerate, the hybrid battery (traction battery)
charge will deplete quickly. Also, EV driving may be canceled by
rapid acceleration or vehicle speed.
● Restrain your speed as much as possible. The distance that can
be driven in EV/EV auto mode will reduce considerably at high
speeds.
*: The EV driving range can be checked using the multi-information dis-
play etc. (P. 212, 228, 235, 252)
■
When in HV mode
The vehicle can be used in the same way as a standard hybrid
vehicle.
In HV mode, controls are primarily carried out as follows in accor-
dance with the driving conditions.
● The gasoline engine stops
* when the vehicle is stopped.
● During start off, the electric motor (traction motor) drives the vehi-
cle.
● During normal driving, the gasoline engine and electric motor
(traction motor) are controlled effectively, and the vehicle is
driven with optimum fuel efficiency. Also, when necessary, the
electric motor (traction motor) operates as an electrical generator
to charge the hybrid battery (traction battery).
● When the accelerator pedal is depressed heavily, drive force
from both the gasoline engine and the electric motor (traction
motor) is used to accelerate.
*: When the hybrid battery (traction battery) requires charging or the
engine is warming up, etc., the gasoline engine will not automatically
stop. (P. 95)

■ When braking (regenerative braking)
The electric motor (traction motor) charges the hybrid battery (trac-
tion battery).
The EV driving range can be extended by actively using this regen-
erative braking to store electricity in the hybrid battery (traction bat-
tery).
Moreover, as fuel consumption is also reduced when in HV mode,
the regenerative braking system can be used effectively.
In order to make EV/EV auto
mode available, charge the hybrid
battery (traction battery) from an
external power source before
using the vehicle.
Even if charging the hybrid battery
(traction battery) has not been
completed, the vehicle can be
driven. However, if there is not
enough charge remaining, it is pos-
sible that the vehicle cannot be
driven in EV/EV auto mode or the
EV driving range will become
shorter.
When driving with the gasoline engine stopped, a sound, which
changes in accordance with the driving speed, will be played in order
to warn people nearby of the vehicle’s approach. The sound will stop
when the vehicle speed exceeds approximately 15 mph (25 km/h).

■ Regenerative braking
In the following situations, kinetic energy is converted to electric energy and
deceleration force can be obtained in conjunction with the recharging of the
hybrid battery (traction battery).
● The accelerator pedal is released while driving with the shift position in D or
B.
● The brake pedal is depressed while driving with the shift position in D or B.
■ EV driving range
● The EV driving range is displayed on the multi-information display etc.
(P. 212, 228, 235, 252)
● The EV driving range changes in accordance with the charge status of the
hybrid battery (traction battery), the speed of the vehicle, etc.
● Even if there is enough charge remaining in the hybrid battery (traction bat-
tery), EV driving may be canceled and both gasoline engine and electric
motor are used depending on the situation. (P. 95)
■ After EV mode has switched to HV mode due to low hybrid battery (trac-
tion battery) charge
If the hybrid battery (traction battery) is regenerated by driving continuously
down a long slope, the EV driving range etc. will be displayed on the multi-
information display and EV mode will be automatically switched to.
If EV mode is not switched to even though EV driving range is being dis-
played, EV mode can be switched to by pressing the EV/HV mode selection
switch.
■ Refilling fuel
Plug-in hybrid vehicles can be driven using electricity charged from an exter-
nal power source. However, as the gasoline engine is used depending on the
situation even if in EV mode, and the gasoline engine is provided on board as
a power source for driving in HV mode, it is needed to refueling the vehicle.
Check the fuel amount and refill immediately when the fuel level becomes
low. (P. 368)

displayed on the multi-information display etc., EV driving (driving using only
the electric motor) may be canceled and both gasoline engine and electric
motor are used depending on the situation (EV driving will be returned to
automatically after EV driving becomes possible again).
EV driving may be canceled automatically in the following circumstances:
● When vehicle speed is more than approximately 84 mph (135 km/h).
● When power is needed temporarily, for example when the accelerator pedal
is depressed firmly or when accelerating suddenly.
*
● When the temperature of the hybrid system is high.
The vehicle has been left in the sun, driven on a hill, driven at high speeds,
etc.
● When the temperature of the hybrid system is low.
● When the heater is switched on when the outside temperature is below
about 14°F (-10°C).
● When the windshield defogger switch is pressed. (P. 504, 514)
● When the system determines that the gasoline engine needs to be started.
The gasoline engine may also operate in circumstances other than those
listed above, depending on conditions.
*: When traveling in the EV auto mode only
■ Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop
automatically in the following conditions
*:
● During gasoline engine warm-up
● During hybrid battery (traction battery) charging
● When the temperature of the hybrid battery (traction battery) is high or low
● When the windshield defogger switch is pressed. (P. 504, 514)
*: Depending on the circumstances, the gasoline engine may also not stop
automatically in situations other than those above.

■ If the vehicle is not used for a long time
● The 12-volt battery may discharge. In this event, charge the 12-volt battery.
(P. 595)
In order to prevent the hybrid battery (traction battery) from becoming
extremely low in charge, charge the hybrid battery (traction battery) from
external power source or start the hybrid system at least once every 2 or 3
months, and turn the power switch off after the gasoline engine has
stopped automatically. (If the gasoline engine does not start up even after
approximately 10 seconds have passed since the “READY” indicator came
on, the power switch can be turned to off without any further action.)
● When the vehicle is left with the charging cable connected, the electricity
consumption amount of the 12-volt battery increases due to controls, such
as the system checking, operating. When the charging cable is not needed,
immediately remove it from the vehicle.
■ Sounds and vibrations specific to a hybrid vehicle
There may be no engine sound or vibration even though the vehicle is able to
move with the “READY” indicator is illuminated. For safety, apply the parking
brake and make sure to shift the shift position to P when parked.
The following sounds or vibrations may occur when the hybrid system is
operating and are not a malfunction.
● Motor sounds may be heard from the engine compartment.
● Sounds may be heard from the hybrid battery (traction battery) when the
hybrid system starts or stops.
● Relay operating sounds such as a snap or soft clank will be emitted from the
hybrid battery (traction battery), behind the rear seats, when the hybrid sys-
tem is started or stopped.
● Sounds from the hybrid system may be heard when the back door is open.
● Sounds may be heard from the transmission when the gasoline engine
starts or stops, when driving at low speeds, or during idling.
● Engine sounds may be heard when accelerating sharply.
● Sounds may be heard due to regenerative braking when the brake pedal is
depressed or as the accelerator pedal is released.
● Vibration may be felt when the gasoline engine starts or stops.
● Cooling fan sounds may be heard from the air intake vent. (P. 99)
■ Vehicle proximity notification system
In the following cases, the vehicle proximity notification system may be diffi-
cult for surrounding people to hear.
● In very noisy areas
● In the wind or the rain
Also, as the vehicle proximity notification system is installed on the front of
the vehicle, it may be more difficult to hear from the rear of the vehicle com-
pared to the front.

There are air intake vents on both
sides of the rear seatback for the
purpose of cooling the hybrid bat-
tery (traction battery). If the vents
are blocked, charging/discharg-
ing of the hybrid battery (traction
battery) may become limited.
When a certain level of impact is detected by the impact sensor, the
emergency shut off system blocks off the high voltage current and
stops the fuel pump to minimize the risk of electrocution and fuel leak-
age. If the emergency shut off system activates, your vehicle will not
restart. To restart the hybrid system, contact your Toyota dealer.
A message is automatically displayed when a malfunction occurs in
the hybrid system or an improper operation is attempted.
If a warning message is shown on
the multi-information display, read
the message and follow the
instructions.

■ If a warning light comes on, a warning message is displayed or the 12-
volt battery is disconnected
The hybrid system may not start. In that case, try to start the system again. If
the “READY” indicator does not come on, contact your Toyota dealer.
■ Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started,
refuel the vehicle with at least enough gasoline to make the low fuel level
warning light (P. 664) go off. If there is only a small amount of fuel, the
hybrid system may not be able to start. (The standard amount of fuel is about
2.0 gal. [7.5 L, 1.7 Imp.gal.], when the vehicle is on a level surface. This value
may vary when the vehicle is on a slope. Add extra fuel when the vehicle is
inclined.)
■ Electromagnetic waves
● High voltage parts and cables on the hybrid vehicles incorporate electro-
magnetic shielding, and therefore emit approximately the same amount of
electromagnetic waves as conventional gasoline powered vehicles or home
electronic appliances.
● Your vehicle may cause sound interference in some third party-produced
radio parts.
■ Effect of magnetic forces
If objects that generate strong magnetic forces, such as large speakers, are
placed inside the luggage compartment or installed nearby, the generated
magnetic forces may negatively affect the hybrid system.
■ Hybrid battery (traction battery) (lithium-ion battery)
The hybrid battery (traction battery) has a limited service life.
The hybrid battery (traction battery) capacity (the ability to hold a charge)
reduces with time and use in the same way as other rechargeable batteries.
The extent at which capacity reduces changes drastically depending on the
environment (ambient temperature, etc.) and usage conditions, such as how
the vehicle is driven and how the hybrid battery (traction battery) is charged.
This is a natural characteristic of lithium-ion batteries, and is not a malfunc-
tion. Also, even though the distance that can be driven in EV mode decreases
when the hybrid battery (traction battery) capacity reduces, vehicle perfor-
mance does not significantly become worse.
In order to reduce the possibility of the capacity reducing, follow the directions
listed on P. 143, “Capacity reduction of the hybrid battery (traction battery)”.
■ Starting the hybrid system in an extremely cold environment
When the hybrid battery (traction battery) is extremely cold (below approxi-
mately -22F [-30C]) under the influence of the outside temperature, it may
not be possible to start the hybrid system. In this case, try to start the hybrid
system again after the temperature of the hybrid battery increases due to the
outside temperature increase etc.

WARNING
■ High voltage precautions
The vehicle has high voltage DC and AC systems as well as a 12-volt sys-
tem. DC and AC high voltage is very dangerous and can cause severe
burns and electric shock that may result in death or serious injury.
● Never touch, disassemble, remove or replace the high voltage parts,
cables or their connectors.
● The hybrid system will become hot after starting as the system uses high
voltage. Be careful of both the high voltage and the high temperature, and
always obey the caution labels attached to the vehicle.
● Never try to open the service plug
access hole located in the luggage
compartment. The service plug is used
only when the vehicle is serviced and is
subject to high voltage.

WARNING
■ Road accident cautions
Observe the following precautions to reduce the risk of death or serious
injury:
● Pull your vehicle off the road, apply the parking brake, shift the shift posi-
tion to P, and turn the hybrid system off.
● Do not touch the high voltage parts, cables and connectors.
● If electric wires are exposed inside or outside your vehicle, an electric
shock may occur. Never touch exposed electric wires.
● Do not touch the battery if liquid is leaking from or adhering to it.
If electrolyte (carbonic-based organic electrolyte) from the hybrid battery
(traction battery) comes into contact with the eyes or skin, it could cause
blindness or skin wounds. In the unlikely event that it comes into contact
with the eyes or skin, wash it off immediately with a large amount of water,
and seek immediate medical attention.
● If electrolyte is leaking from the hybrid battery (traction battery), do not
approach the vehicle.
Even in the unlikely event that the hybrid battery (traction battery) is dam-
aged, the internal construction of the battery will prevent a large amount of
electrolyte from leaking out. However, any electrolyte that does leak out
will give off a vapor. This vapor is an irritant to skin and eyes and could
cause acute poisoning if inhaled.
● Do not bring burning or high-temperature items close to the electrolyte.
The electrolyte may ignite and cause a fire.
● If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible.
Never use a fire extinguisher that is not meant for electric fires. Using even
a small amount of water may be dangerous.
● If your vehicle needs to be towed, do so with front wheels raised. If the
wheels connected to the electric motor (traction motor) are on the ground
when towing, the motor may continue to generate electricity. This may
cause a fire. (P. 655)
● Carefully inspect the ground under the vehicle. If you find that liquid has
leaked onto the ground, the fuel system may have been damaged. Leave
the vehicle as soon as possible.

WARNING
■ Hybrid battery (traction battery)
● Your vehicle contains a sealed lithium-ion battery.
● Never resell, hand over or modify the hybrid battery. To prevent accidents,
hybrid batteries that have been removed from a disposed vehicle are col-
lected through Toyota dealer. Do not dispose of the battery yourself.
Unless the battery is properly collected, the following may occur, resulting
in death or serious injury:
• The hybrid battery may be illegally disposed of or dumped, and it is haz-
ardous to the environment or someone may touch a high voltage part,
resulting in an electric shock.
• The hybrid battery is intended to be used exclusively with your hybrid
vehicle. If the hybrid battery is used outside of your vehicle or modified
in any way, accidents such as electric shock, heat generation, smoke
generation, an explosion and electrolyte leakage may occur.
When reselling or handing over your vehicle, the possibility of an acci-
dent is extremely high because the person receiving the vehicle may
not be aware of these dangers.
● If your vehicle is disposed of without the hybrid battery having been
removed, there is a danger of serious electric shock if high voltage parts,
cables and their connectors are touched. In the event that your vehicle
must be disposed of, the hybrid battery must be disposed of by your
Toyota dealer or a qualified service shop. If the hybrid battery is not dis-
posed of properly, it may cause electric shock that can result in death or
serious injury.

NOTICE
■ Hybrid battery (traction battery) air vents
● Make sure not to block the air intake vent with anything, such as a seat
cover, plastic cover, or luggage. If the vents are blocked, the charging/dis-
charging of the hybrid battery (traction battery) may become limited.
● When dust etc. has accumulated in the air intake vent, clean it with a vac-
uum cleaner to prevent the vent from clogging.
● Do not wet or allow foreign substances to enter the air vents as this may
cause a short circuit and damage the hybrid battery (traction battery).
● Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the hybrid battery (traction battery), the battery
may be damaged. Have the vehicle inspected by your Toyota dealer.
● A filter is installed to the air intake vent. When the filter remains noticeably
dirty even after cleaning the air intake vent, filter cleaning or replacement
is recommended. When cleaning the filter, refer to P. 570.
■ Notice about fuel
● For plug-in hybrid vehicles, fuel may remain in the tank for a long time and
undergo changes in quality depending on the how the vehicle is used.
Refuel at least 5.3 gal. (20 L, 4.4 Imp.gal.) of fuel every 12 months (refuel
a total of at least 5.3 gal. [20 L, 4.4 Imp.gal.] over a 12-month period), as
this may affect components of the fuel system or the gasoline engine.
● If the vehicle has not been refueled for a certain amount of time and it is
possible that the quality of the fuel remaining in the tank has changed, “No
new fuel has been added recently. Please refuel” is displayed on the multi-
information display when the power switch is turned to ON mode. If the
message is displayed, refuel the vehicle immediately.

Plug-in hybrid vehicle driving tips
◆ Using EV mode and HV mode effectively
Primarily using EV mode when driving in cities and using HV mode
when driving on highways (or freeways) can help conserve fuel and
electricity. (P. 90)
◆ Using Eco drive mode
When using Eco drive mode, the torque corresponding to the accel-
erator pedal depression amount can be generated more smoothly
than it is in normal conditions. In addition, the operation of the air
conditioning system (heating/cooling) will be minimized, improving
fuel and electricity economy. (P. 419)
◆ Use of Hybrid System Indicator
Eco-friendly driving is possible by keeping the Hybrid System Indi-
cator within Eco area. (P. 223)
◆ Shift position operation
Shift the shift position to D when stopped at a traffic light, or driving
in heavy traffic etc. Shift the shift position to P when parking. When
using the N, there is no positive effect on fuel consumption. In the
N, the gasoline engine operates but electricity cannot be gener-
ated. Also, when using the air conditioning system, etc., the hybrid
battery (traction battery) power is consumed.
For economical and ecological driving, pay attention to the fol-
lowing points:
106
PRIUS PRIME_OM_OM47C77U_(U)
2-1. Plug-in hybrid system
◆ Accelerator pedal/brake pedal operation
● Drive your vehicle smoothly. Avoid abrupt acceleration and
deceleration. Gradual acceleration and deceleration will make
more effective use of the electric motor (traction motor) without
having to use gasoline engine power.
● Avoid repeated acceleration. Repeated acceleration consumes
hybrid battery (traction battery) power, resulting in poor fuel con-
sumption. Battery power can be restored by driving with the
accelerator pedal slightly released.
◆ When braking
Make sure to operate the brakes gently and a timely manner. A
greater amount of electrical energy can be regenerated when slow-
ing down.
◆ Delays
Repeated acceleration and deceleration, as well as long waits at
traffic lights, will lead to high fuel and electricity consumption.
Check traffic reports before leaving and avoid delays as much as
possible. When driving in a traffic jam, gently release the brake
pedal to allow the vehicle to move forward slightly while avoiding
overuse of the accelerator pedal. Doing so can help control exces-
sive electricity and fuel consumption.
◆ Highway driving
● Control and maintain the vehicle at a constant speed. Before
stopping at a toll booth or similar, allow plenty of time to release
the accelerator and gently apply the brakes. A greater amount of
electrical energy can be regenerated when slowing down.
● Electricity consumption will increase significantly when driving at
high speeds in EV mode. If there will be a long distance to the
next external charging point after leaving a freeway, it is recom-
mended to drive in HV mode while on the freeway and change to
EV mode after leaving the freeway.
PRIUS PRIME_OM_OM47C77U_(U)
107
2-1. Plug-in hybrid system
2
Plug-in hybrid system
◆ Air conditioning
● Turn the “A/C” switch (
*
1
• *
2
) off when it is
not needed. Doing so can help reduce excessive electricity and
fuel consumption.
In summer: When the ambient temperature is high, use the recir-
culated air mode. Doing so will help to reduce the burden on the
air conditioning system and reduce electricity and fuel consump-
tion as well.
In winter: Avoid excessive and unnecessary use of the heater.
Usage of the heated steering wheel (if equipped) and seat heat-
ers is effective. (P. 526)
● Using the Remote Air Conditioning System (P. 522) while the
charging cable is connected to the vehicle can reduce electricity
consumption immediately after starting off by operating air condi-
tioning mainly using electricity from an external power source.
● When setting the timer, selecting the start time setting mode and
setting “Climate Prep” to “On” can reduce electricity consumption
immediately after starting off by operating air conditioning before
charging is completed. (P. 157)
*

*
2
: Vehicles with 11.6-inch display
◆ Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. If there is
improper tire inflation pressure in the tires, the EV driving range will
become shorter, and fuel consumption when in HV mode will
increase.
Also, as snow tires can cause large amounts of friction, their use on
dry roads can lead to increased fuel and electricity consumption.
◆ Luggage
Carrying heavy luggage will lead to poor fuel economy. Avoid carry-
ing unnecessary luggage. Installing a large roof rack will also cause
poor fuel economy.
◆ Warming up before driving
Since the gasoline engine starts up and cuts out automatically,
warming up is not necessary.

2-1. Plug-in hybrid system
EV driving range
The value displayed on the multi-information display etc. (P. 212,
228, 235, 252) is estimated from the following information.
● The amount of hybrid battery (traction battery) charge currently
remaining
● The electricity consumption (the estimated distance that can be
driven in EV mode per unit of electrical energy) based on the
recorded value
● Past air conditioning system electricity consumption amount
The electricity consumption varies depending on how the vehicle is
driven. The vehicle automatically records the electricity consumption
when being charged and uses the electricity consumption for estimat-
ing the EV driving range. Therefore, the EV driving range displayed
when the hybrid battery (traction battery) is fully charged may differ
from the previous EV driving range depending on how the vehicle was
driven.
The EV driving range may change significantly with each charging
until the electricity consumption based on the recorded value is stable
(for approximately the first month or two). However, this does not indi-
cate a malfunction.
When the air conditioning system is turned on, the EV driving range
(with using the air conditioning system) is estimated based on the past
air conditioning electricity consumption amount considering that the
electricity consumption may become higher.
The EV driving range displayed on the multi-information display
etc. shows the reference distance that EV driving (driving using
only the electric motor) is possible, and the actual distance that
can be driven may differ from that displayed.
Even if the EV driving range is displayed, EV driving may be can-
celed and both gasoline engine and electric motor are used depend-
ing on the situation. (P. 95)

The distance that can be driven in EV mode varies significantly
depending on how the vehicle is driven, road conditions, the weather,
the outside temperature, usage conditions of electrical components
and the number of occupants.
The distance that can be driven in EV mode can be extended if the fol-
lowing is performed:
● Maintain a safe distance from the vehicle in front and avoid unnec-
essary acceleration and deceleration
● Accelerate and decelerate the vehicle as smoothly as possible
● Drive at moderate speeds as much as possible and maintain a con-
stant speed
● Set the air conditioning to a moderate temperature and turn the “A/C”
switch (
*

• *
2
) off when it is not needed
● Use tires of the specified size and maintain the specified tire pres-
sure
● Use the EV/HV mode selection switch to drive in HV mode when
driving on a highway
Electricity consumption will increase substantially when driving on a
highway in EV mode.
● Do not add unnecessary weight to the vehicle

Things to know before charging
This vehicle has been designed to allow charging from an external
power source using a charging cable for exclusive use with standard
household AC outlets.
However, the vehicle differs greatly from standard household electri-
cal goods in the following ways, and incorrect usage could cause fire
or electric shock, possibly leading to death or serious injury.
● The charging operation is designed to operate at 12A continuously
for the charge duration (up to 5 hours 10 minutes). (P. 134)
● Charging can be conducted outdoors.
To charge properly, follow the procedure after reading the explanation
below. Charging is intended to be carried out by licensed drivers only
who properly understand the charging procedure.
● Charging should not be carried out by children.
● When charging with a charging equipment, follow the procedures
for using each equipment.
● When charging using a public charging facility, check the setting of
the charging timer function.
• When the charge schedule is registered, temporarily turn off the
function or turn “Charge Now” on. (P. 164, 166, 174, 175)
• When the charge schedule is set to ON, charging will not start
even if the charging cable is connected. Also, charging fee may
occur due to connection of the charging cable.
Make sure to read the following precautions before connecting
the charging cable to the vehicle and charging the hybrid battery
(traction battery).
Charging precautions
142
PRIUS PRIME_OM_OM47C77U_(U)
2-2. Charging
Before charging, always check the following items.
● The parking brake is applied. (P. 349)
● The headlights are switched off or set to AUTO, and lights such as
the emergency flashers and interior lights etc. are switched off.
If these light switches are turned ON, then these features will consume
electricity, and charging time will increase.
● The power switch is off. (P. 336)
Before charging, make sure that each part of the charging cable is in
good condition. (P. 120)
■ Safety functions
● The hybrid system will not start while the charging cable is attached to the
vehicle, even if the power switch is operated.
● If the charging cable is connected while the “READY” indicator is illumi-
nated, the hybrid system will stop automatically and driving will not be possi-
ble.
● When the charging cable is connected to the vehicle, the shift position can-
not be changed from P to another position.
■ During charging
The followings occur, however, it does not indicate a malfunction.
● The charging starting time may differ depending on the state of the vehicle.
● During charging, the sound of the fan may be heard from the charging
equipment cooling air intake vents. (P. 145)

■ Capacity reduction of the hybrid battery (traction battery)
The capacity of the hybrid battery (traction battery) will decline gradually
when the hybrid battery (traction battery) is in use. The rate at which it
declines will differ in accordance with environmental conditions and the way
in which the vehicle is used. Observing the following can help suppress bat-
tery capacity decline.
● Avoid parking the vehicle in areas with a high temperature under direct sun-
light when the hybrid battery (traction battery) is fully charged.
● Avoid accelerating and decelerating frequently and suddenly when EV driv-
ing.
● Avoid frequent driving near the top speed for EV driving. (P. 95)
● Leave a low level of charge in the hybrid battery (traction battery) when
leaving the vehicle undriven for a long period of time.
After confirming that EV mode has switched to HV mode, turn the power
switch off.
● Use the charging timer function as much as possible in order to fully
charge the hybrid battery (traction battery) immediately before starting
off. (P. 157)
Also, if the hybrid battery (traction battery) capacity reduces, the distance that
can be driven in EV mode decreases. However, vehicle performance does
not significantly become worse.
■ When the remaining charge of the hybrid battery (traction battery) is low
after charging
In the following situations, the remaining charge of the hybrid battery (traction
battery) after charging completes may be less than normal in order to protect
the system (the EV driving range after the battery is fully charged may be
shorter).
*
● Charging is carried out when the outside temperature is low or high
● Charging is carried out immediately after high-load driving or in extreme
heat
When none of the above situations apply and there is a drastic drop in the
remaining charge of the hybrid battery (traction battery) after charging com-
pletes, have the vehicle inspected by your Toyota dealer.
*: When this occurs, even if the remaining charge display of the hybrid battery
(traction battery) shows that it is fully charged, the remaining charge rapidly
decreases faster than normal.
■ When the charging amount sent to the hybrid battery (traction battery)
decreases
When the amount of power supplied by the charging equipment is low or
operation of the “Traction Battery Heater”, etc., reduces the charging power
sent to the hybrid battery (traction battery), the charging amount sent to the
hybrid battery (traction battery) may decrease.

● The charge schedule cannot be set while driving.
● A maximum of 15 charge schedules can be registered.
■ To make sure that the charging timer function operates correctly
Check the following items.
● Adjust the clock to the correct time (P. 197)
● The calendar is set to the correct date (P. 199)
● Check that the power switch is turned off
● After registering the charge schedule, connect the charging cable
The charging start time is determined based on the charge schedule at the
time that the charging cable was connected.
● After connecting the charging cable, check that the charging indicator
flashes (P. 114)
● Do not use an outlet that has a power cut off function (including a timer func-
tion)

power is cut off due to a timer function, etc., charging may not be carried
out according to plan if the power is cut off during the set time.
■ When the charging cable remains connected to the vehicle
Even if multiple consecutive charge schedules are registered, the next
charge will not be carried out according to the timer until the charging cable is
removed and reconnected after charging completes. Also, when the hybrid
battery (traction battery) is fully charged, charging according to the timer will
not be carried out.
■ “Climate Prep”
● When the air conditioning-linked setting is turned on, the air conditioning
operates until the set departure time. Therefore, the air conditioning will con-
sume electricity and charging may not complete by the set departure time.
● If the hybrid battery (traction battery) is fully charged, charging will not be
carried out, even if the charge schedule is set. However, if “Climate Prep” is
turned on, the air conditioning will operate only once when it nears the time
set in “Departure”. If this occurs, the air conditioning will consume electricity
and the remaining charge of the hybrid battery (traction battery) when
departing may be decreased.

driving is performed and equivalent to the fuel consumption for the gasoline
vehicles. For this vehicle, driven distance per kWh of electricity consumed
(“miles/kWh”) is displayed as electricity consumption on each screen.
When the unit is set to “km/h”:
Electricity consumption is the consumption rate of the electricity when EV
driving is performed and equivalent to the fuel consumption for the gasoline
vehicles. For this vehicle, electricity consumed per 100 km (“kWh/100 km”) is
displayed as electricity consumption on each screen.

• The shift position is not D or B.
● The Eco score and “ECO Accelerator Guidance” stop operating in the fol-
lowing situations.
• The Hybrid System Indicator is not operating.
• Dynamic radar cruise control with full-speed range is being used.
■ Display of the remaining hybrid battery (traction battery)
● The current amount of the remaining hybrid battery (traction battery) is dis-
played in the Hybrid System Indicator or the sub-screen on the main display.
(P. 215)
• The remaining battery for EV driving in EV mode is displayed in green,
and the remaining battery used in HV mode is displayed in blue.
• The amount of the remaining battery displayed decrease as the vehicle is
driven and increase when the hybrid battery (traction battery) is charged,
electrical energy is regenerated using the regenerative braking (P. 94)
or electricity is generated by the gasoline engine.
• If the remaining battery is not displayed in green, HV mode is automati-
cally selected and EV mode cannot be used. To enable EV driving,
charge the hybrid battery (traction battery). (P. 110)
● The amount of the hybrid battery (traction battery) in HV mode is automati-
cally controlled by the hybrid system. The amount of remaining hybrid battery
(traction battery) in HV mode may not reach the top line
* even if electrical
energy is regenerated using the regenerative braking (P. 94) or electricity
is generated by the gasoline engine. However, this does not indicate a mal-
function. Also, even if the display of the remaining hybrid battery (traction
battery) exceeds the top line, the display is shown in blue until the vehicle
returns to EV mode.
*: The position of the boundary line between EV mode and HV mode on the
display of the remaining hybrid battery (traction battery).
● Depending on the charging situation, when the display of the remaining
hybrid battery (traction battery) is shown during charging, charging contin-
ues even after the display of the remaining hybrid battery (traction battery)
shows a fully charged state. However, this does not indicate a malfunction.

■ Remaining charge amount warning of hybrid battery (traction battery)
● The buzzer sounds intermittently when the hybrid battery (traction battery)
remains without charging while the shift position is in N, or the remaining
charge amount drops below a certain level.
If the remaining charge amount drops further, the buzzer sounds continu-
ously.
● When a warning message is shown on the multi-information display and the
buzzer sounds, follow the instructions displayed on the screen to perform
troubleshooting.
■ About the Eco score
● After starting off, Eco score display does not start until the vehicle speed
exceeds approximately 12 mph (20 km/h).
● In addition to the vehicle driving status, the Eco score also evaluates the air
conditioning system usage condition (P. 241). The score displayed when
the hybrid system stops is the total result of the driving status after the
hybrid system starts and the air conditioning usage condition.
■ “EV Energy” and “EV Distance” display
The rate at which the “EV Energy” and “EV Distance” remaining amount
decreases depends on the driving conditions of the vehicle. Also, the “EV
Energy” and “EV Distance” remaining amount may decrease due to system
power consumption even though the vehicle is not being driven.
■ Predictive Efficient Drive (Predictive Deceleration Support)
(vehicles with 11.6-inch display)
When a predictive deceleration support point registered in the navigation sys-
tem is approached, the system turns off the Eco accelerator guide and
informs the driver of releasing the accelerator pedal early.

unlocked or locked by anyone.
● Even if the electronic key is not inside the vehicle, it may be possible to start
the hybrid system if the electronic key is near the window.
● The doors may unlock if a large amount of water splashes on the door han-
dle, such as in the rain or in a car wash when the electronic key is within the
effective range. (The door will automatically be locked after approximately
60 seconds if the doors are not opened and closed.)

tive range, the door may lock and unlock repeatedly. In this case, follow the
following correction procedures to wash the vehicle.
• Place the electronic key in a location 6 ft. (2 m) or more away from the
vehicle. (Take care to ensure that the key is not stolen.)
• Set electronic key to battery-saving mode to disable the smart key sys-
tem. (P. 292)
● If the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, a message may be shown on the multi-information dis-
play and a buzzer will sound outside the vehicle. To turn off the alarm, lock
all the doors.
● The lock sensor may not work properly if it comes into contact with ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again.
● A sudden approach to the effective range or door handle may prevent the
doors from being unlocked. In this case, return the door handle to the origi-
nal position and check that the doors unlock before pulling the door handle
again.
● If there is another electronic key in the detection area, it may take slightly
longer to unlock the doors after the door handle is gripped.

ventional vehicles, and it is necessary to refrain from activities such as sud-
den acceleration. Refer to “Plug-in hybrid vehicle driving tips” (P. 105).
■ Driving in the rain
● Drive carefully when it is raining, because visibility will be reduced, the win-
dows may become fogged-up, and the road will be slippery.
● Drive carefully when it starts to rain, because the road surface will be espe-
cially slippery.
● Refrain from high speeds when driving on an expressway in the rain,
because there may be a layer of water between the tires and the road sur-
face, preventing the steering and brakes from operating properly.

■ Restraining the hybrid system output (Brake Override System)
● When the accelerator and brake pedals are depressed at the same time, the
hybrid system output may be restrained.
● A warning message is displayed on the multi-information display while the
system is operating. (P. 677)
■ “ECO Accelerator Guidance” (P. 226)
It is easier to drive in an Eco-friendly manner by driving while referring to the
“ECO Accelerator Guidance” display. Also, by using the “ECO Accelerator
Guidance”, it is easier to increase the Eco score evaluation.
● When starting off:
While staying within the “ECO Accelerator Guidance” range, gradually
depress the accelerator pedal and accelerate to the desired speed. If exces-
sive acceleration is avoided, the “Eco-Start” score will increase.
● When driving:
After accelerating to the desired speed, release the accelerator pedal and
drive at a stable speed within the “ECO Accelerator Guidance” range. By
keeping the vehicle within the “ECO Accelerator Guidance” range, the “Eco-
Cruise” score will increase.
● When stopping:
When stopping the vehicle, early releasing the accelerator pedal will cause
the “Eco-Stop” score to increase.
■ Restraining sudden start (Drive-Start Control)
● When the following unusual operation is performed, the hybrid system out-
put may be restrained.
• When the shift position is shifted from R to D/B, D/B to R, N to R, P to D/
B
*, P to R* with the accelerator pedal depressed, a warning message
appears on the multi-information display. If a warning message is shown
on the multi-information display, read the message and follow the instruc-
tions.
• When the accelerator pedal is depressed too much while the vehicle is in
reverse.
● While Drive-Start Control is being activated, your vehicle may have trou-
ble escaping from the mud or fresh snow. In such case, deactivate TRAC
(P. 490) to cancel Drive Start Control so that the vehicle may become
able to escape from the mud or fresh snow.
*: Depending on the situation, the shift position may not be changed.

Driving
■ Breaking in your new Toyota
To extend the life of the vehicle, observing the following precautions is recom-
mended:
● For the first 200 miles (300 km):
Avoid sudden stops.
● For the first 600 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive at a constant speed for extended periods.
■ Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. (P. 720)
■ For efficient use
● Shift the shift position to D when driving.
In the N position, the gasoline engine operates but electricity cannot be gen-
erated. The hybrid battery (traction battery) will discharge, requiring unnec-
essary engine power to charge.
● Drive your vehicle smoothly.
Avoid abrupt acceleration and deceleration. Gradual acceleration and decel-
eration will make more effective use of the electric motor (traction motor)
without having to use gasoline engine power.
● Avoid repeated acceleration.
Repeated acceleration consumes hybrid battery (traction battery) power,
resulting in poor acceleration. Battery power can be restored by driving with
the accelerator pedal slightly released.
● Shift the shift position to P when parking.
In the N position, the hybrid battery (traction battery) does not charge. Leav-
ing the shift position in the N position for an extended period of time may
discharge the hybrid battery (traction battery). The vehicle cannot run if the
hybrid battery (traction battery) is discharged.

● Do not drive if you are unfamiliar with the location of the brake and accel-
erator pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake
pedal will result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to a diffi-
culty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the
vehicle only slightly. This allows you to depress the brake and accelera-
tor pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake
pedal using your left foot may delay response in an emergency, result-
ing in an accident.
● The driver should pay extra attention to pedestrians when the vehicle is
powered only by the electric motor (traction motor). As there is no engine
noise, the pedestrians may misjudge the vehicle’s movement. Even
though the vehicle is equipped with the vehicle proximity notification sys-
tem, drive with care as pedestrians in the vicinity may still not notice the
vehicle if the surrounding area is noisy.
● Do not drive the vehicle over or stop the vehicle near flammable materials
such as leaves, paper or rags.
The exhaust system and exhaust gases can be extremely hot. These hot
parts may cause a fire if there is any flammable material nearby.
● During normal driving, do not turn off the hybrid system. Turning the hybrid
system off while driving will not cause loss of steering or braking control,
however, power assist to the steering will be lost. This will make it more
difficult to steer smoothly, so you should pull over and stop the vehicle as
soon as it is safe to do so.
In the event of an emergency, such as if it becomes impossible to stop the
vehicle in the normal way: P. 653

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■ When driving the vehicle
● Use engine braking (shift position B instead of shift position D) to maintain
a safe speed when driving down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. (P. 343)
● Do not adjust the positions of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control.
● Always check that all passengers’ arms, head or other parts of their body
are not outside the vehicle.
● Do not drive across river crossings or through other bodies of water.
This may cause electric/electronic components to short circuit, damage
the hybrid system or cause other serious damage to the vehicle.
● Do not drive in excess of the speed limit. Even if the legal speed limit per-
mits it, do not drive over 85 mph (140 km/h) unless your vehicle has high-
speed capability tires. Driving over 85 mph (140 km/h) may result in tire
failure, loss of control and possible injury. Be sure to consult a tire dealer
to determine whether the tires on your vehicle are high-speed capability
tires or not before driving at such speeds.
■ When driving on slippery road surfaces
● Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle.
● Sudden acceleration, engine braking due to shifting, or changes in engine
speed could cause the vehicle to skid, resulting in an accident.
● After driving through a puddle, depress the brake pedal to make sure that
the brakes are functioning properly. Wet brake pads may prevent the
brakes from functioning properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■ When shifting the shift position
● Do not let the vehicle roll backward while a forward driving position is
selected, or roll forward while the shift position is in R.
Doing so may result in an accident or damage to the vehicle.
● Do not shift the shift position to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle
control.
● Do not shift the shift position to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
● Do not shift the shift position to a driving position while the vehicle is mov-
ing backward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
● Changing the shift position to N while the vehicle is moving will disengage
the hybrid system. Engine braking is not available with the hybrid system
disengaged.
● Be careful not to change the shift position with the accelerator pedal
depressed.
Changing the shift position to any position other than P or N may lead to
unexpected rapid acceleration of the vehicle that may cause an accident
and result in death or serious injury.
After changing the shift position, make sure to confirm the current shift
position displayed on the shift position indicator inside the meter.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■ If you hear a squealing or scraping noise (brake pad wear limit indica-
tors)
Have the brake pads checked and replaced by your Toyota dealer as soon
as possible.
Rotor damage may result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads
and/or those of the brake discs are exceeded.
■ When the vehicle is stopped
● Do not depress the accelerator pedal unnecessarily.
If the shift position is in any position other than P or N, the vehicle may
accelerate suddenly and unexpectedly, causing an accident.
● In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while stopped with the “READY” indicator is
illuminated, and apply the parking brake as necessary.
● If the vehicle is stopped on an incline, in order to prevent accidents caused
by the vehicle rolling forward or backward, always depress the brake pedal
and securely apply the parking brake as needed.
● Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause
the exhaust system to overheat, which could result in a fire if combustible
material is nearby.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■ When the vehicle is parked
● Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in
the vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and
plastic material of glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the
interior of the vehicle, and may also cause a short circuit in the vehicle’s
electrical components.
● Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a
place such as the glove box or on the floor, it may be lit accidentally when
luggage is loaded or the seat is adjusted, causing a fire.
● Do not attach adhesive discs to the windshield or windows. Do not place con-
tainers such as air fresheners on the instrument panel or dashboard. Adhe-
sive discs or containers may act as lenses, causing a fire in the vehicle.
● Do not leave a door or window open if the curved glass is coated with a
metallized film such as a silver-colored one. Reflected sunlight may cause
the glass to act as a lens, causing a fire.
● Always apply the parking brake, shift the shift position to P, stop the hybrid
system and lock the vehicle.
Do not leave the vehicle unattended while the “READY” indicator is illumi-
nated.
If the vehicle is parked with the shift position in P but the parking brake is
not set, the vehicle may start to move, possibly leading to an accident.
● Do not touch the exhaust pipe while the “READY” indicator is illuminated
or immediately after turning the hybrid system off.
Doing so may cause burns.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■ When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidentally move the
shift lever or depress the accelerator pedal, this could cause an accident or
fire due to hybrid system overheating. Additionally, if the vehicle is parked in
a poorly ventilated area, exhaust gases may collect and enter the vehicle,
leading to death or a serious health hazard.
■ When braking
● When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause
one side of the vehicle to brake differently than the other side. Also, the
parking brake may not securely hold the vehicle.
● If the electronically controlled assist function does not operate, do not fol-
low other vehicles closely and avoid downhill or sharp turns that require
braking.
In this case, braking is still possible, but the brake pedal should be
depressed more firmly than usual. Also, the braking distance will increase.
Have your brakes fixed immediately.
● The brake system consists of 2 or more individual hydraulic systems; if
one of the systems fails, the other(s) will still operate. In this case, the
brake pedal should be depressed more firmly than usual and the braking
distance will increase. Have your brakes fixed immediately.

■ When driving the vehicle
● Do not depress the accelerator and brake pedals at the same time during
driving, as this may restrain the hybrid system output.
● Do not use the accelerator pedal or depress the accelerator and brake
pedals at the same time to hold the vehicle on a hill.
■ When parking the vehicle
Always set the parking brake, and shift the shift position to P. Failure to do
so may cause the vehicle to move or the vehicle may accelerate suddenly if
the accelerator pedal is accidentally depressed.
■ Avoiding damage to vehicle parts
● Do not turn the steering wheel fully in either direction and hold it there for
an extended period of time.
Doing so may damage the power steering motor.
● When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.
■ If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehi-
cle.
● It may be difficult to control your vehicle.

■ When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage to the vehicle:
● Engine stalling
● Short in electrical components
● Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your Toyota dealer check the following:
● Brake function
● Changes in quantity and quality of oil and fluid used for the engine, hybrid
transmission, etc.
● Lubricant condition for the bearings and suspension joints (where possi-
ble), and the function of all joints, bearings, etc.
If the shift control system is damaged by flooding, it may not be possible to
shift the shift position to P, or from P to other positions. When the shift posi-
tion cannot be changed from P to any other position, the front wheels will
lock, and you will be unable to tow the vehicle with the front wheels on the
ground, as the front wheels may be locked. In this case, transport the vehi-
cle with both front wheels or all four wheels lifted. (P. 655)

Cargo and luggage
Cargo capacity depends on the total weight of the occupants.
(Cargo capacity) = (Total load capacity) — (Total weight of occupants)
Steps for Determining Correct Load Limit
(1) Locate the statement “The combined weight of occupants and
cargo should never exceed XXX kg or XXX lbs.” on your vehicle’s
placard.
(2) Determine the combined weight of the driver and passengers that
will be riding in your vehicle.
(3) Subtract the combined weight of the driver and passengers from
XXX kg or XXX lbs.
(4) The resulting figure equals the available amount of cargo and lug-
gage load capacity.
For example, if the “XXX” amount equals 1400 lbs. and there will be
five 150 lb passengers in your vehicle, the amount of available
cargo and luggage load capacity is 650 lbs. (1400 750 (5150) =
650 lbs.)
(5) Determine the combined weight of luggage and cargo being loaded
on the vehicle. That weight may not safely exceed the available
cargo and luggage load capacity calculated in Step 4.
(6) If your vehicle will be towing a trailer, load from your trailer will be
transferred to your vehicle. Consult this manual to determine how
this reduces the available cargo and luggage load capacity of your
vehicle. (P. 333)
Toyota does not recommend towing a trailer with your vehicle. Your
vehicle is not designed for trailer towing.
Take notice of the following information about storage precau-
tions, cargo capacity and load.

Cargo capacity
Total load capacity (vehicle
capacity weight) (P. 718)
When 2 people with the combined weight of A lb. (kg) are riding in
your vehicle, which has a total load capacity (vehicle capacity weight)
of B lb. (kg), the available amount of cargo and luggage load capacity
will be C lb. (kg) as follows:
B
*

lb. (kg) = C*
3
lb. (kg)
*
1
: A = Weight of people
*
2
: B = Total load capacity
*
3
: C = Available cargo and luggage load
In this condition, if 3 more passengers with the combined weight of
D lb. (kg) get on, the available cargo and luggage load will be reduced
E lb. (kg) as follows:
C lb. (kg) D*
4
lb. (kg) = E*
5
lb. (kg)
*
4
: D = Additional weight of people
*
5
: E = Available cargo and luggage load
As shown in the example above, if the number of occupants
increases, the cargo and luggage load will be reduced by an amount
that equals the increased weight due to the additional occupants. In
other words, if an increase in the number of occupants causes an
excess of the total load capacity (combined weight of occupants plus
cargo and luggage load), you must reduce the cargo and luggage on
your vehicle.

position is in R.
■ Restraining sudden start (Drive-Start Control)
P. 320
■ Automatic P position selection function
● If the power switch is on and the shift position is not already P, completely
stopping the vehicle and pressing the power switch causes the shift position
to automatically switch to P and the power switch to turn off.
*
● The shift position may also automatically switch to P if one of the following
conditions is detected while the vehicle is stopped by dynamic radar cruise
control with full-speed range.
• Driver’s seat belt is not fastened
• Driver’s door is opened
• Approximately 3 minutes elapse after the vehicle stopped
*: If the power switch is pressed when driving at very low speeds (for exam-
ple, just before the vehicle stops), the shift position may automatically
switch to P. Press the power switch after completely stopping the vehicle to
prevent unexpected sudden stopping of the vehicle.
■ If the shift position cannot be shifted from P
There is a possibility that the 12-volt battery is discharged. Check the 12-volt
battery in this situation. (P. 703)
■ About engine braking
When shift position B is selected, releasing the accelerator pedal will apply
engine braking.
● When the vehicle is driven at high speeds, compared to ordinary gasoline-
fueled vehicles, the engine braking deceleration is felt less than that of other
vehicles.
● The vehicle can be accelerated even when shift position B is selected.
If the vehicle is driven continuously in the B position, fuel efficiency will
become low. Usually, select the D position.

When the shift position does not switch due to a mistaken operation, system
conditions, etc., or when the attempted shift operation is invalid, a message
indicating the correct operation or the reason why switching cannot be per-
formed is shown on the multi-information display. In these cases, follow the
instructions and retry the operation.
■ Customization
Settings (e.g. reverse warning buzzer) can be changed.
(Customizable features: P. 741)
WARNING
■ When driving on slippery road surfaces
Do not accelerate or shift the shift position suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.
■ Shift lever and P position switch
● Do not remove the shift lever knob or use anything but a genuine Toyota
shift lever knob. Also, do not hang anything on the shift lever.
Doing so could prevent the shift lever from returning to position, causing
unexpected accidents to occur when the vehicle is in motion.
● Do not press the P position switch while the vehicle is moving.
If the P position switch is pressed when driving at very low speeds (for
example, just before the vehicle stops), the vehicle may stop suddenly
when the shift position switches to P, which could lead to an accident.
● In order to prevent the shift position from accidentally being changed, do
not touch the shift lever or P position switch when not using them.

WARNING
■ When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do
so may result in death or serious injury.
● After exiting the vehicle and before opening the fuel door, touch an
unpainted metal surface to discharge any static electricity. It is important to
discharge static electricity before refueling because sparks resulting from
static electricity can cause fuel vapors to ignite while refueling.
● Always hold the grips on the fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosened.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out of the filler neck and cause injury.
● Do not allow anyone that has not discharged static electricity from their
body to come close to an open fuel tank.
● Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
● Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
● Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition
hazard.
■ When refueling
Observe the following precautions to prevent fuel overflowing from the fuel
tank:
● Securely insert the fuel nozzle into the fuel filler neck.
● Stop filling the tank after the fuel nozzle automatically clicks off.
● Do not top off the fuel tank.

PCS (Pre-Collision System)
◆ Pre-collision warning
When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound and a warning message
will be displayed on the multi-
information display to urge the
driver to take evasive action.
The pre-collision system uses a radar sensor and camera sen-
sor to detect vehicles and pedestrians in front of your vehicle.
When the system determines that the possibility of a frontal col-
lision with a vehicle or pedestrian is high, a warning operates to
urge the driver to take evasive action and the potential brake
pressure is increased to help the driver avoid the collision. If the
system determines that the possibility of a frontal collision with
a vehicle or pedestrian is extremely high, the brakes are auto-
matically applied to help avoid the collision or help reduce the
impact of the collision.
The pre-collision system can be disabled/enabled and the warning
timing can be changed. (P. 385)
382
PRIUS PRIME_OM_OM47C77U_(U)
5-5. Using the driving support systems
◆ Pre-collision brake assist
When the system determines that the possibility of a frontal colli-
sion is high, the system applies greater braking force in relation to
how strongly the brake pedal is depressed.
◆ Pre-collision braking
When the system determines that the possibility of a frontal colli-
sion is high, the system warns the driver. If the system determines
that the possibility of a frontal collision is extremely high, the brakes
are automatically applied to help avoid the collision or reduce the
collision speed.

WARNING
■ Limitations of the pre-collision system
● The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
Do not use the pre-collision system instead of normal braking operations
under any circumstances. This system will not prevent collisions or lessen
collision damage or injury in every situation. Do not overly rely on this sys-
tem. Failure to do so may lead to an accident, resulting in death or serious
injury.
● Although this system is designed to help avoid a collision or help reduce
the impact of the collision, its effectiveness may change according to vari-
ous conditions, therefore the system may not always be able to achieve
the same level of performance.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• Conditions under which the system may operate even if there is no pos-
sibility of a collision: P. 387
• Conditions under which the system may not operate properly: P. 389
● Do not attempt to test the operation of the pre-collision system yourself.
Depending on the objects used for testing (dummies, cardboard objects
imitating detectable objects, etc.), the system may not operate properly,
possibly leading to an accident.
■ Pre-collision braking
● When the pre-collision braking function is operating, a large amount of
braking force will be applied.
● If the vehicle is stopped by the operation of the pre-collision braking func-
tion, the pre-collision braking function operation will be canceled after
approximately 2 seconds. Depress the brake pedal as necessary.
● The pre-collision braking function may not operate if certain operations are
performed by the driver. If the accelerator pedal is being depressed
strongly or the steering wheel is being turned, the system may determine
that the driver is taking evasive action and possibly prevent the pre-colli-
sion braking function from operating.
● In some situations, while the pre-collision braking function is operating,
operation of the function may be canceled if the accelerator pedal is
depressed strongly or the steering wheel is turned and the system deter-
mines that the driver is taking evasive action.
● If the brake pedal is being depressed, the system may determine that the
driver is taking evasive action and possibly delay the operation timing of
the pre-collision braking function.

● When your vehicle is towing another vehicle
● When transporting the vehicle via truck, boat, train or similar means of
transportation
● When the vehicle is raised on a lift with the hybrid system on and the tires
are allowed to rotate freely
● When inspecting the vehicle using a drum tester such as a chassis
dynamometer or speedometer tester, or when using an on vehicle wheel
balancer
● When a strong impact is applied to the front bumper or front grille, due to
an accident or other reasons
● If the vehicle cannot be driven in a stable manner, such as when the vehi-
cle has been in an accident or is malfunctioning
● When the vehicle is driven in a sporty manner or off-road
● When the tires are not properly inflated
● When the tires are very worn
● When tires of a size other than specified are installed

■ Operational conditions
The pre-collision system is enabled and the system determines that the pos-
sibility of a frontal collision with a vehicle or pedestrian is high.
Each function is operational at the following speeds:
● Pre-collision warning:
• Vehicle speed is between approximately 7 and 110 mph (10 and 180 km/h).
(For detecting a pedestrian, vehicle speed is between approximately 7 and
50 mph [10 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or pedestrian
ahead is approximately 7 mph (10 km/h) or more.
● Pre-collision brake assist:
• Vehicle speed is between approximately 20 and 110 mph (30 and 180 km/h).
(For detecting a pedestrian, vehicle speed is between approximately 20 and
50 mph [30 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or pedestrian
ahead is approximately 20 mph (30 km/h) or more.
● Pre-collision braking:
• Vehicle speed is between approximately 7 and 110 mph (10 and 180 km/h).
(For detecting a pedestrian, vehicle speed is between approximately 7 and
50 mph [10 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or pedestrian
ahead is approximately 7 mph (10 km/h) or more.
The system may not operate in the following situations:
● If a 12-volt battery terminal has been disconnected and reconnected and
then the vehicle has not been driven for a certain amount of time
● If the shift position is in R
● If VSC is disabled (only the pre-collision warning function will be opera-
tional)
■ Pedestrian detection function
■ Cancelation of the pre-collision braking
If either of the following occur while the pre-collision braking function is oper-
ating, it will be canceled:
● The accelerator pedal is depressed strongly.
● The steering wheel is turned sharply or abruptly.
The pre-collision system detects pedestri-
ans based on the size, profile, and motion
of a detected object. However, a pedes-
trian may not be detected depending on
the surrounding brightness and the
motion, posture, and angle of the
detected object, preventing the system
from operating properly. (P. 391)

WARNING
■ Before using LDA system
Do not rely solely upon the LDA system. The LDA system does not auto-
matically drive the vehicle or reduce the amount of attention that must be
paid to the area in front of the vehicle. The driver must always assume full
responsibility for driving safely by paying careful attention to the surround-
ing conditions and operating the steering wheel to correct the path of the
vehicle. Also, the driver must take adequate breaks when fatigued, such as
from driving for a long period of time.
Failure to perform appropriate driving operations and pay careful attention
may lead to an accident, resulting in death or serious injury.
■ To avoid operating LDA system by mistake
When not using the LDA system, use the LDA switch to turn the system off.
■ Situations unsuitable for LDA system

WARNING
■ Before using dynamic radar cruise control with full-speed range
● Driving safely is the sole responsibility of the driver. Do not rely solely on
the system, and drive safely by always paying careful attention to your sur-
roundings.
● The dynamic radar cruise control with full-speed range provides driving
assistance to reduce the driver’s burden. However, there are limitations to
the assistance provided.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• When the sensor may not be correctly detecting the vehicle ahead:
P. 417
• Conditions under which the vehicle-to-vehicle distance control mode
may not function correctly:P. 418
● Set the speed appropriately depending on the speed limit, traffic flow, road
conditions, weather conditions, etc. The driver is responsible for checking
the set speed.
● Even when the system is functioning normally, the condition of the preced-
ing vehicle as detected by the system may differ from the condition
observed by the driver. Therefore, the driver must always remain alert,
assess the danger of each situation and drive safely. Relying solely on this
system or assuming the system ensures safety while driving can lead to
an accident, resulting in death or serious injury.
● Switch the dynamic radar cruise control with full-speed range off using the
“ON-OFF” button when not in use.

WARNING
■ Cautions regarding the driving assist systems
Observe the following precautions, as there are limitations to the assistance
provided by the system.
Failure to do so may cause an accident resulting in death or serious injury.
● Assisting the driver to measure following distance
The dynamic radar cruise control with full-speed range is only intended to
help the driver in determining the following distance between the driver’s
own vehicle and a designated vehicle traveling ahead. It is not a mecha-
nism that allows careless or inattentive driving, and it is not a system that
can assist the driver in low-visibility conditions. It is still necessary for
driver to pay close attention to the vehicle’s surroundings.
● Assisting the driver to judge proper following distance
The dynamic radar cruise control with full-speed range determines
whether the following distance between the driver’s own vehicle and a
designated vehicle traveling ahead is within a set range. It is not capable
of making any other type of judgement. Therefore, it is absolutely neces-
sary for the driver to remain vigilant and to determine whether or not there
is a possibility of danger in any given situation.
● Assisting the driver to operate the vehicle
The dynamic radar cruise control with full-speed range does not include
functions which will prevent or avoid collisions with vehicles ahead of your
vehicle. Therefore, if there is ever any possibility of danger, the driver must
take immediate and direct control of the vehicle and act appropriately in
order to ensure the safety of all involved.

WARNING
■ Situations unsuitable for dynamic radar cruise control with full-speed
range
Do not use dynamic radar cruise control with full-speed range in any of the
following situations.
Doing so may result in inappropriate speed control and could cause an acci-
dent resulting in death or serious injury.
● Roads where there are pedestrians, cyclists, etc.
● In heavy traffic
● On roads with sharp bends
● On winding roads
● On slippery roads, such as those covered with rain, ice or snow
● On steep downhills, or where there are sudden changes between sharp up
and down gradients
Vehicle speed may exceed the set speed when driving down a steep hill.
● At entrances to freeways and highways
● When weather conditions are bad enough that they may prevent the sen-
sors from detecting correctly (fog, snow, sandstorm, heavy rain, etc.)
● When there is rain, snow, etc. on the front surface of the radar sensor or
camera sensor
● In traffic conditions that require frequent repeated acceleration and decel-
eration
● During emergency towing
● When an approach warning buzzer is heard often

This mode employs a radar sensor to detect the presence of vehicles
up to approximately 328 ft. (100 m) ahead, determines the current
vehicle-to-vehicle following distance, and operates to maintain a suit-
able following distance from the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on long
downhill slopes.

Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-
vehicle distance can also be set by operating the vehicle-to-vehicle dis-
tance switch.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system applies the brakes (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pushing the
cruise control lever up or depressing the accelerator pedal will resume fol-
low-up cruising.
Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.

WARNING
■ Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
The Blind Spot Monitor function is a supplementary function which alerts the
driver that a vehicle is present in the blind spot. Do not overly rely on the
Blind Spot Monitor function. The function cannot judge if it is safe to change
lanes, therefore over reliance could cause an accident resulting in death or
serious injury.
According to conditions, the system may not function correctly. Therefore
the driver’s own visual confirmation of safety is necessary.

■ Sensor detection information
● The sensor’s detection areas are limited to the areas around the vehicle’s
bumper.
● Depending on the shape of the obstacle and other factors, the detection dis-
tance may shorten, or detection may be impossible.
● Obstacles may not be detected if they are too close to the sensor.
● There will be a short delay between obstacle detection and display. Even
when traveling at a low speed, if you come too close to an obstacle before
the display and buzzer activate, the display and buzzer may not activate at
all.
● Thin posts or objects lower than the sensor may not be detected when
approached, even if they have been detected once.
● It might be difficult to hear beeps due to the volume of audio system or air
flow noise of the air conditioning system.
■ Obstacle warning function
When an obstacle in the side areas is within the vehicle course while the
vehicle is moving forward or backward, this function inform the driver by the
display and the buzzer. (P. 435, 436)
■ Obstacle detection in side areas
● Obstacles in the side areas are detected while driving by scanning the side
areas with the side sensors. Recognized obstacles are retained in memory
for up to approximately 2 minutes.
● Obstacles may not be detected in the side areas until the scan completes.
After the power switch is turned on, scanning completes after driving the
vehicle for a short period of time.
● When an obstacle such as another vehicle, pedestrian or animal is detected
by the side sensors, the obstacle may continue to be detected even after it
has left the side sensor detection area.

abnormal display, or obstacles may not be detected.
● The sensor is covered in any way.
● In harsh sunlight or intense cold weather
● On an extremely bumpy road, on an incline, on gravel, or on grass
● The vicinity of the vehicle is noisy due to vehicle horns, motorcycle
engines, air brakes of large vehicles, or other loud noises producing ultra-
sonic waves.
● The sensor is splashed with water or drenched with heavy rain.
● The sensor is drenched with water on a flooded road.
● The vehicle is leaning considerably to one side.
● The vehicle is equipped with a fender pole or wireless antenna.
● The vehicle is approaching a tall or curved curb.
● The area directly under the bumpers is not detected.
● If obstacles draw too close to the sensor.
● The bumper or sensor receives a strong impact.
● A non-genuine Toyota suspension (lowered suspension etc.) is installed.
● There is another vehicle equipped with parking assist sensors in the vicin-

WARNING
■ Side sensors
In the following situations, the intuitive parking assist may not operate nor-
mally and may result in an unexpected accident. Drive carefully.
● Obstacles may not be detected in the side areas until the vehicle is driven
for a short time and a scan of the side areas is completed. (P. 438)
● Even after the scan of the side areas is completed, obstacles such as
other vehicles, people or animals that approach from the sides cannot be
detected.
● Even after the scan of the side areas is completed, obstacles may not be
detected depending on the surrounding situation of the vehicle.
At that time, the side sensor operation displays (P. 434) temporary turn
off.
■ Obstacles which may not be properly detected
The shape of the obstacle may prevent the sensor from detecting it. Pay
particular attention to the following obstacles:
● Wires, fences, ropes, etc.
● Cotton, snow and other materials that absorb sound waves
● Sharply-angled objects
● Low obstacles
● Tall obstacles with upper sections projecting outwards in the direction of
your vehicle
● People may not be detected if they are wearing certain types of clothing.
● Moving objects such as people or animals

sensor malfunction etc. Have the vehicle checked by your Toyota dealer.
● Intuitive parking assist operation display flashes, and a beep sounds when
no obstacles are detected.
● If the area around a sensor collides with something, or is subjected to
strong impact.
● If the bumper collides with something.
● If the display shows up and remains on without a beep.
● If a display error occurs, first check the sensor.
If the error occurs even when there is no ice, snow or mud on the sensor, it
is likely that the sensor is malfunctioning.
■ Notes when washing the vehicle
● Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.
● When using steam to wash the vehicle, do not direct steam too close to
the sensors. The sensors may not function properly if subjected to steam.

The system operates in the following situations when an obstacle is
detected in the traveling direction of the vehicle.
◆ The vehicle is driven at low speeds and the brake pedal is not
depressed, or is depressed too late
◆ The accelerator pedal is depressed too far
: If equipped
When a collision may occur with an obstacle while parking or
traveling at low speeds, when the vehicle suddenly moves for-
ward due to mistaken accelerator pedal operation, or when the
vehicle moves due to the wrong shift position being selected,
the sensors detect obstacles to the front or rear in the traveling
direction of the vehicle, and the system operates to lessen
impact with obstacles such as walls, and reduce resulting dam-
age.

■ Sensor detection range
The detection range of the Parking Support Brake function differs from the
detection range of the intuitive parking assist. (P. 437)
Therefore, even if the intuitive parking assist detects an obstacle and pro-
vides a warning, the Parking Support Brake function may not start operating.
■ System operation
When the vehicle is stopped by system operation, the Parking Support Brake
function stops and the PKSB OFF indicator illuminates.
■ System recovery
When the Parking Support Brake function is stopped by system operation
and you would like to resume operation, either turn the Parking Support
Brake function on again (P. 444), or turn the power switch off and then back
on. Furthermore, when the vehicle moves with an obstacle no longer in the
traveling direction of the vehicle, or when the traveling direction of the vehicle
changes (such as when switching from moving forward to backing up, and
vice versa), system operation automatically resumes.
■ Obstacles not detected by the sensors
The following obstacles may not be detected by the sensors.
● Objects such as people, cloth and snow, that are difficult for sonic waves to
reflect off of. (In particular, people may also not be detected depending on
the type of clothing they are wearing.)
● Objects not perpendicular with the ground, objects not at a right angle to the
traveling direction of the vehicle, uneven objects or waving objects
● Low objects

■ Situations when the system may operate even though there is no possi-
bility of a collision
In the following situations, the system may operate even though there is no
possibility of a collision.
● Environmental influence
• The vehicle is driven toward a banner or flag, a low-hanging branch or a
boom barrier (such as those used at railroad crossings, toll gates and
parking lots).
• There is an obstacle on the shoulder of the road (when the vehicle is
driven in a narrow tunnel, on a narrow bridge or on a narrow road)
• The vehicle is being parallel parked
• There is a rut or hole in the surface of the road
• When the vehicle is driven on a metal cover (grating), such as those used
for drainage ditches
• The vehicle is driven on a steep slope
• The sensor is covered by water on a flooded road
● Influence from the weather
• Ice, snow, dirt, etc., has adhered to the sensor (if removed, the system
returns to normal)
• Heavy rain or water strikes the vehicle
• In severe weather such as fog, snow or a sand storm
● Influence from other sonic waves
• An ultrasonic wave source is nearby, such as the horn or parking assist
sensors of another vehicle, a vehicle detector, a motorcycle engine or the
air brake of a large vehicle
• Electronic components (such as a backlit license plate (especially fluo-
rescent types), fog lights, a fender pole or a wireless antenna) are
installed near the sensors
• The vehicle is driven on a narrow
road
• The vehicle is driven on a gravel road
or in an area with tall grass

● Changes in the vehicle
• The vehicle is tilted a large amount
• The height of the vehicle has drastically changed due to the carried load
(the nose tilts up or down)
• The direction of the sensor has deviated due to a collision or other impact
■ In the unlikely event that the Parking Support Brake function mistakenly
operates at a crossing or elsewhere
Even in the unlikely event that the Parking Support Brake function mistakenly
operates at a crossing or elsewhere, brake control is canceled after approxi-
mately 2 seconds, allowing you to proceed forward and leave the area. Fur-
thermore, brake control is also canceled when the brake pedal is depressed.
Depressing the accelerator pedal again allows you to proceed forward and
leave the area.
■ Situations in which the system may not operate normally
In the following situations, the system may not operate normally.
● Environmental influence
• There is an obstacle that cannot be detected between the vehicle and
another obstacle that can be detected
• An obstacle such as another vehicle, a motorcycle, a bicycle or a pedes-
trian cuts in front of the vehicle or jumps out from the side.
● Influence from the weather
• Ice, snow, dirt, etc., has adhered to the sensor (if removed, the system
returns to normal)
• Heavy rain or water strikes the vehicle
• In severe weather such as fog, snow or a sand storm
• The area around the sensor is
extremely hot or cold
• The wind is strong

■ When removing and installing the 12-volt battery
The system needs to be initialized.
The system can be initialized by driving the vehicle straight ahead for 5 sec-
onds or more at a speed of approximately 22 mph (35 km/h) or higher.
■ When “PKSB Unavailable” is displayed on the multi-information display
and the PKSB OFF indicator flashes
● Ice, snow, dirt, etc., may have adhered to the sensor. If this occurs, remove
the ice, snow, dirt, etc., from the sensor to return the system to normal.
Also, a warning message may be displayed at low temperatures due to ice
forming on the sensor, and the sensor may not detect obstacles. Once the
ice melts, the system will return to normal.
● If this message is shown even after removing dirt from the sensor, or shown
when the sensor was not dirty to begin with, have the vehicle inspected at
your Toyota dealer.
● System initialization may not have been performed after removal and instal-
lation of the 12-volt battery. Perform system initialization.
■ When “PKSB Malfunction Visit Your Dealer” is displayed on the multi-

WARNING
■ For safe use
Do not rely solely upon the system. Relying solely upon the system may
lead to an unexpected accident.
● Driving safely is the sole responsibility of the driver. Pay careful attention
to the surrounding conditions in order to ensure safe driving. The Parking
Support Brake function can provide support to lessen the severity of colli-
sions. However, it may not operate depending on the situation.
● The Parking Support Brake function is not a system designed to com-
pletely stop the vehicle. Furthermore, even if the Parking Support Brake
function is able to stop the vehicle, brake control is canceled after approxi-
mately 2 seconds, so depress the brake pedal immediately.
■ In order for the system to operate properly
Make sure to observe the following precautions regarding the sensors
(P. 444). Failure to observe these precautions may cause the sensors
not to operate properly, and may result in an unexpected accident.
● Do not perform work such as modification, disassembly or painting
● Only perform replacements using genuine parts
● Do not subject the area around the sensors to any impacts
● Do not damage the sensors, and always keep them clean
■ Handling the suspension
Do not modify the suspension, as changes to the height or incline of the
vehicle may prevent the sensors from correctly detecting obstacles, may
cause the system not operate, or may cause the system to operate unnec-
essarily.

NOTICE
■ Preventing sensor malfunctions
● If the area around a sensor is subjected to an impact, equipment may not
operate properly due to a sensor malfunction. Have the vehicle inspected
at your Toyota dealer.
● When using a high-pressure washer to wash the vehicle, do not spray
water directly on the sensors. The sensors may not function properly if
subjected to an impact from strong water pressure.
● When using steam to wash the vehicle, do not direct steam too close to
the sensors. The sensors may not function properly if subjected to steam.
■ Preventing unnecessary operation
In the following situations, turn the Parking Support Brake function off. The
system may operate even though there is no possibility of a collision.
● A chassis roller, chassis dynamo, free roller or similar equipment is being
used for an inspection, etc.
● The vehicle is being loaded onto a ship, truck or other transport vessel
● The suspension has been lowered or tires that have a different size than
the genuine tires are equipped

S-APGS (Simple Advanced Parking Guidance
System)
■ Function summary
The Simple Advanced Parking Guidance System automatically
operates the steering wheel to provide support when backing into
an area near a target parking spot, and when departing from a par-
allel parking spot. (Changing the shift position and speed adjust-
ment when moving forward or backing up are not performed
automatically.)
● The Simple Advanced Parking Guidance System does not park
the vehicle automatically. It is a system that provides support
when pulling out of a perpendicular or parallel parking spot.
● The Simple Advanced Parking Guidance System provides steer-
ing wheel operation assistance to guide the vehicle toward the
selected intended parking spot. The selected intended parking
spot may not always be reachable, depending on road and vehi-
cle conditions at the time of parking, and the distance to the
intended parking spot.
■ Linking with the Parking Support Brake function
While the Simple Advanced Parking Guidance System is operating,
if the system detects an obstacle that could result in a collision, the
emergency brakes operate, regardless of whether the Parking Sup-
port Brake function is on or off. (P. 457)

■ Parking Support Brake function while the Simple Advanced Parking
Guidance System is operating
While the Simple Advanced Parking Guidance System is operating, if the sys-
tem detects an obstacle that could result in a collision, hybrid system output
restriction control and brake control of the Parking Support Brake function are
operated, regardless of whether the Parking Support Brake function is on or
off. (P. 444)
● After the Parking Support Brake function operates, operation of the Simple
Advanced Parking Guidance System is temporarily stopped, and operation
of the Parking Support Brake function is indicated on the multi-information
display. (P. 448)
● When operation of the Simple Advanced Parking Guidance System is
stopped 3 times by operation of the Parking Support Brake function, the
Simple Advanced Parking Guidance System is canceled.
● Once the Simple Advanced Parking Guidance System becomes available
after the Parking Support Brake function is operated, a message prompting
you to shift is displayed on the multi-information display. Operation of the
Simple Advanced Parking Guidance System can be resumed by shifting
according to the prompt on the multi-information display and pressing the
S-APGS switch (P. 458) again.
■ Shifting while the Simple Advanced Parking Guidance System is operat-
ing

■ Tips for using the back-in parking assist mode
● Depending on the condition of the park-
ing space, if there is not enough space
in front of the vehicle required to perform
the parking operation, the target parking
spot may not be reachable.
Intended parking spot
Wall
● Leave a gap of approximately 3.3 ft. (1
m) from any parked vehicles and
approach the target parking spot. If the
gap between your vehicle and any
parked vehicles is too large, the front
side sensors and rear side sensors may
not be able to detect the parked vehi-
cles.
● Stop so that the center of the target
parking spot is perpendicular to the vehi-
cle. Furthermore, only push the S-APGS
switch when the vehicle is at a complete
stop.
NOTICE
● If the road surface has any dips or inclines, the target parking spot cannot
be correctly set. Therefore, the vehicle may be parked at an angle or may
deviate from the parking spot. In these cases, do not use the back-in park-
ing assist mode.
● When parking in a narrow space, the vehicle will come close to adjacent
vehicles. If it seems the vehicle may make contact, stop the vehicle by
depressing the brake pedal.
● It may not be possible to detect objects that are low to the ground. Directly
confirm the safety of your surroundings and, if it seems the vehicle may
make contact with an obstacle, stop the vehicle by depressing the brake
pedal.
● Depending on the surrounding environment, such as other parked vehi-
cles, the vehicle may be parked at an angle or may deviate from the park-
ing spot. Manually adjust vehicle alignment as necessary.

not operate effectively on steep inclines and roads covered with ice.
● Unlike the parking brake, hill-start assist control is not intended to hold the
vehicle stationary for an extended period of time. Do not attempt to use
hill-start assist control to hold the vehicle on an incline, as doing so may
lead to an accident.
■ When the TRAC/ABS/VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.

Winter driving tips
● Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine/power control unit coolant
• Washer fluid
● Have a service technician inspect the condition of the 12-volt bat-
tery.
● Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the front tires.
Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
Perform the following according to the driving conditions:
● Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing.
● To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
● Check for and remove any excess ice or snow that may have accu-
mulated on the exterior lights, vehicle’s roof, chassis, around the
tires or on the brakes.
● Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.

5-6. Driving tips
Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to road con-
ditions.
Park the vehicle and shift the shift position to P and block the wheel
under the vehicle without setting the parking brake. The parking brake
may freeze up, preventing it from being released. If the vehicle is
parked without setting the parking brake, make sure to block the
wheels.
Failure to do so may be dangerous because it may cause the vehicle
to move unexpectedly, possibly leading to an accident.
Use the correct tire chain size when mounting the tire chains. Chain
size is regulated for each tire size.
Side chain
0.12 in. (3.0 mm)
1.18 in. (30.0 mm)
0.39 in. (10.0 mm)
Cross chain
0.16 in. (4.0 mm)
0.98 in. (25.0 mm)
0.55 in. (14.0 mm)
Regulations regarding the use of tire chains vary depending on loca-
tion and type of road. Always check local regulations before installing
chains.

■ Tire chain installation
Observe the following precautions when installing and removing chains:
● Install and remove tire chains in a safe location.
● Install tire chains on the front tires only. Do not install tire chains on the rear
tires.
● Install tire chains on front tires as tightly as possible. Retighten chains after
driving 1/4 - 1/2 mile (0.5 - 1.0 km).
● Install tire chains following the instructions provided with the tire chains.
■ Consumption of fuel and electricity
In cold temperatures, resistance of the parts of a vehicle (transmission, tires,
etc.) generally increases, resulting in increase of energy consumption. As a
result, fuel economy is likely to decrease.
Consumption of fuel and electricity of this vehicle is also likely to become
worse in cold temperatures.
WARNING
■ Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
● Use tires of the specified size.
● Maintain the recommended level of air pressure.
● Do not drive in excess of 75 mph (120 km/h), regardless of the type of
snow tires being used.
● Use snow tires on all, not just some wheels.
■ Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
● Do not drive in excess of the speed limit specified for the tire chains being
used, or 30 mph (50 km/h), whichever is lower.
● Avoid driving on bumpy road surfaces or over potholes.
● Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
● Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
● Do not use LDA (Lane Departure Alert with steering control).
■ When parking the vehicle
When parking the vehicle without applying the parking brake, make sure to
chock the wheels. If you do not chock the wheels, the vehicle may move
unexpectedly, possibly resulting in an accident.

■ Heating
● In HV mode, the gasoline engine may operate in order to extract heat from
the engine coolant via the heater.
● In EV mode, heating is done by a heat pump system.
• When the outside temperature is low or it is snowing, compared to con-
ventional vehicles, heating may be less effective and warm air may not
come out.
• If frost has formed on the outside heat exchanger, the heating perfor-
mance will decline. The frost can be removed from the outside heat
exchanger by operating the Remote Air Conditioning System before driv-
ing (P. 522). When frosted over, the heating operation of the Remote
Air Conditioning System starts after defrosting.
• When is turned on, the heating is controlled optimally. Therefore,
the set heating performance may not be achieved even if the fan speed
setting is increased.
● In the following situations the gasoline engine may operate in order to
extract heat from the engine coolant via the heater even in EV mode.
• The outside temperature is approximately 14°F (-10°C) or low
• is operating
■ Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and
the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after is pressed.
■ Water droplets during air conditioning operation
• When the outside heat exchanger is
frosted over, fan speed declines and it
may become harder to heat the inte-
rior. However, it is not a malfunction.
In this situation, the air temperature
from the outlets may not change even
though the set temperature is raised.
The outside heat exchanger, accumulator
and air conditioning piping may incur con-
densation or frost may form. During or
after the air conditioning operation, water
droplets may fall from the vehicle. How-
ever, it is not a malfunction.

cle after closing the windows, it is recommended that the air intake mode be
set to outside air mode and the fan speed to any setting except off.
■ Outside/recirculated air mode
● Setting to the recirculated air mode temporarily is recommended in prevent-
ing dirty air from entering the vehicle interior and helping to cool the vehicle
when the outside air temperature is high.
● Outside/recirculated air mode may automatically switch depending on the
temperature setting or the inside temperature.
■ Fresh air intake system while parking
When parking, the system automatically switches to outside air mode to
encourage better air circulation throughout the vehicle, helping to reduce
odors that occur when starting the vehicle.
■ Operation of the air conditioning system in the air conditioning eco
mode
● In the air conditioning eco mode, the air conditioning system is controlled as
follows to prioritize fuel efficiency:
• Engine speed and compressor operation controlled to restrict heating/
cooling capacity
• Fan speed restricted when automatic mode is selected
● To improve air conditioning performance, perform the following operations:
• Adjust the fan speed

Close all windows. If dust thrown up by the vehicle is still drawn into the vehi-
cle after closing the windows, it is recommended that the air intake mode be
set to outside air mode and the fan speed to any setting except off.
■ Outside/recirculated air mode
● Setting to the recirculated air mode temporarily is recommended in prevent-
ing dirty air from entering the vehicle interior and helping to cool the vehicle
when the outside air temperature is high.
● Outside/recirculated air mode may automatically switch depending on the
temperature setting or the inside temperature.
■ Fresh air intake system while parking
When parking, the system automatically switches to outside air mode to
encourage better air circulation throughout the vehicle, helping to reduce
odors that occur when starting the vehicle.
■ Operation of the air conditioning system in the air conditioning eco
mode
● In the air conditioning eco mode, the air conditioning system is controlled as
follows to prioritize fuel efficiency:
• Engine speed and compressor operation controlled to restrict heating/
cooling capacity
• Fan speed restricted when automatic mode is selected
● To improve air conditioning performance, perform the following operations:
• Adjust the fan speed
• Adjust the temperature setting
• Turn off the air conditioning eco mode
● When the driving mode is set to Eco driving mode, the air conditioning eco
mode will be turned on automatically. Even in this case, the air conditioning
eco mode can be turned off by selecting . (P. 419)
■ When the outside temperature falls to nearly 32F (0C)
The dehumidification function may not operate even when is
selected.
■ Ventilation and air conditioning odors
● To let the fresh air in, set the air conditioning system to the outside air mode.
● During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.
● In order to suppress odors that occur when the air conditioning system
starts, fresh air is automatically taken in when parked.
● To reduce potential odors from occurring, the start timing of the blower may
be delayed for a short period of time immediately after the air conditioning
system is started in automatic mode.

WARNING
■ To prevent the windshield from fogging up
● Do not use during cool air operation in extremely humid weather. The
difference between the temperature of the outside air and that of the wind-
shield can cause the outer surface of the windshield to fog up, blocking
your vision.
■ To prevent burns
Do not touch the rear view mirror surfaces when the outside rear view mirror
defoggers are on.
● Do not place anything on the instrument
panel which may cover the air outlets.
Otherwise, air flow may be obstructed,
preventing the windshield defoggers
from defogging.

Remote Air Conditioning System
If the Remote Air Conditioning System is used while the charging
cable is connected to the vehicle, the reduction of charge in the hybrid
battery (traction battery) will be suppressed to allow you to use elec-
tricity from an external power source.
Charging will be conducted automatically after the Remote Air Condition-
ing System is stopped.
Check the temperature setting of the air conditioning system.
(P. 500, 512)
The Remote Air Conditioning System will operate in accordance with the
temperature settings of the air conditioning system.

Maintenance and care
Your vehicle is equipped with a tire pressure warning system that uses
tire pressure warning valves and transmitters to detect low tire infla-
tion pressure before serious problems arise.
If the tire pressure drops below a predetermined level, the driver is
warned by a warning light. (P. 665)
◆ Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new ID codes must be registered in the tire pressure
warning computer and the tire pressure warning system must be
initialized. Have tire pressure warning valve and transmitter ID
codes registered by your Toyota dealer. (P. 604)

Maintenance and care
■ When to replace your vehicle’s tires
Tires should be replaced if:
● The treadwear indicators are showing on a tire.
● You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric, and bulges indicating internal damage.
● A tire goes flat repeatedly or cannot be properly repaired due to the size
or location of a cut or other damage.
If you are not sure, consult with your Toyota dealer.
■ Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not reg-
istered, the tire pressure warning system will not work properly. After driv-
ing for about 20 minutes, the tire pressure warning light blinks for 1
minute and stays on to indicate a system malfunction.
■ Tire life
Any tire over 6 years old must be checked by a qualified technician even
if it has seldom or never been used or damage is not obvious.
■ Routine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation
pressure checks. Make sure to check tire inflation pressure as part of
your routine of daily vehicle checks.
■ Maximum load of tire
Check that the maximum load of the replacement tire is greater than 1/2
of the Gross Axle Weight Ratings (GAWR) of either the front axle or the
rear axle, whichever is greater.
For the GAWR, see the Certification
Label. For the maximum load of the tire,
see the load limit at maximum cold tire
inflation pressure mentioned on the
sidewall of the tire. (P. 730)

■ Tire types
● Summer tires
Summer tires are high-speed performance tires best suited to highway
driving under dry conditions. Since summer tires do not have the same
traction performance as snow tires, summer tires are inadequate for
driving on snow-covered or icy roads. For driving on snow-covered
roads or icy roads, the use of snow tires is recommended. When install-
ing snow tires, be sure to replace all four tires.
● All season tires
All season tires are designed to provide better traction in snow and to
be adequate for driving in most winter conditions as well as for use
year-round. All season tires, however, do not have adequate traction
performance compared with snow tires in heavy or loose snow. Also, all
season tires fall short in acceleration and handling performance com-
pared with summer tires in highway driving.
● Snow tires
For driving on snow-covered roads or icy roads, we recommend using
snow tires. If you need snow tires, select tires of the same size, con-
struction and load capacity as the originally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tires without
first checking local regulations for possible restrictions. Snow tires
should be installed on all wheels. (P. 495)
■ If the tread on snow tires wears down below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is lost.

electrical noise
• When carrying a portable radio, cellular phone, cordless phone or
other wireless communication device
● When the vehicle is parked, the time taken for the warning to start or go
off could be extended.
● When tire inflation pressure declines rapidly for example when a tire has
burst, the warning may not function.
■ The initialization operation
● Make sure to carry out initialization after adjusting the tire inflation pres-
sure.
Also, make sure the tires are cold before carrying out initialization or tire
inflation pressure adjustment.
● If you have accidentally turned the power switch off during initialization,
it is not necessary to press the reset switch again as initialization will
restart automatically when the power switch has been turned to ON
mode for the next time.
● If you accidentally press the reset switch when initialization is not neces-
sary, adjust the tire inflation pressure to the specified level when the
tires are cold, and conduct initialization again.

WARNING
■ When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as
dangerous handling characteristics, which may lead to an accident
resulting in death or serious injury.
● Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
● Do not use tire sizes other than those recommended by Toyota.
● Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
● Do not mix summer, all season and snow tires.
● Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
■ When initializing the tire pressure warning system
Do not initialize the tire pressure warning system without first adjusting
the tire inflation pressure to the specified level. Otherwise, the tire pres-
sure warning light may not come on even if the tire inflation pressure is
low, or it may come on when the tire inflation pressure is actually nor-
mal.

NOTICE
■ Repairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps
● When removing or fitting the wheels, tires or the tire pressure warning
valves and transmitters, contact your Toyota dealer as the tire pres-
sure warning valves and transmitters may be damaged if not handled
correctly.
● Make sure to install the tire valve caps. If the tire valve caps are not
installed, water could enter the tire pressure warning valves and the
tire pressure warning valves could be bound.
● When replacing tire valve caps, do not use tire valve caps other than
those specified. The cap may become stuck.
■ To avoid damage to the tire pressure warning valves and transmit-
ters
When a tire is repaired with liquid sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sealant is
used, contact your Toyota dealer or other qualified service shop as soon
as possible. After use of liquid sealant, make sure to replace the tire
pressure warning valve and transmitter when repairing or replacing the
tire. (P. 603)
■ Driving on rough roads
Take particular care when driving on roads with loose surfaces or pot-
holes.
These conditions may cause losses in tire inflation pressure, reducing
the cushioning ability of the tires. In addition, driving on rough roads
may cause damage to the tires themselves, as well as the vehicle’s
wheels and body.
■ If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Maintenance and care
■ Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
● Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours or has not been
driven for more than 1 mile or 1.5 km, you will get an accurate cold tire
inflation pressure reading.
● Always use a tire pressure gauge.
It is difficult to judge if a tire is properly inflated based only on its appear-
ance.
● It is normal for the tire inflation pressure to be higher after driving as
heat is generated in the tire. Do not reduce tire inflation pressure after
driving.
● Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is
balanced.
WARNING
■ Proper inflation is critical to save tire performance
Keep your tires properly inflated.
If the tires are not properly inflated, the following conditions may occur
which could lead to an accident resulting in death or serious injury:
● Excessive wear
● Uneven wear
● Poor handling
● Possibility of blowouts resulting from overheated tires
● Air leaking from between tire and wheel
● Wheel deformation and/or tire damage
● Greater possibility of tire damage while driving (due to road hazards,
expansion joints, sharp edges in the road, etc.)
NOTICE
■ When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.
If a valve cap is not installed, dirt or moisture may get into the valve and
cause an air leak, resulting in decreased tire inflation pressure.

Wheels
When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim width and
inset
*.
Replacement wheels are available at your Toyota dealer.
*: Conventionally referred to as “offset”.
Toyota does not recommend using the following:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
● Use only Toyota wheel nuts and wrenches designed for use with
your aluminum wheels.
● When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).
● Be careful not to damage the aluminum wheels when using tire
chains.
● Use only Toyota genuine balance weights or equivalent and a plas-
tic or rubber hammer when balancing your wheels.
If a wheel is bent, cracked or heavily corroded, it should be
replaced. Otherwise, the tire may separate from the wheel or
cause a loss of handling control.

Maintenance and care
■ When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning
valves and transmitters that allow the tire pressure warning system to
provide advance warning in the event of a loss in tire inflation pressure.
Whenever wheels are replaced, tire pressure warning valves and trans-
mitters must be installed. (P. 603)
WARNING
■ When replacing wheels
● Do not use wheels that are a different size from those recommended in
the Owner’s Manual, as this may result in a loss of handling control.
● Never use an inner tube in a leaking wheel which is designed for a
tubeless tire. Doing so may result in an accident, causing death or seri-
ous injury.
■ When installing the wheel nuts
● Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened,
leading to bolt or disc wheel damage. In addition, the oil or grease can
cause the wheel nuts to loosen and the wheel may fall off, causing an
accident and resulting in death or serious injury. Remove any oil or
grease from the wheel bolts or wheel nuts.
■ Use of defective wheels prohibited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possibly causing
an accident.
● Be sure to install the wheel nuts with
the tapered ends facing inward.
Installing the nuts with the tapered
ends facing outward can cause the
wheel to break and eventually cause
the wheel to come off while driving,
which could lead to an accident
resulting in death or serious injury.

● If the lights do not turn on even after the fuse has been replaced, a bulb may
need replacement. (P. 643)
● If the replaced fuse blows again, have the vehicle inspected by your Toyota
dealer.
■ If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
■ When replacing light bulbs
Toyota recommends that you use genuine Toyota products designed for this
vehicle. Because certain bulbs are connected to circuits designed to prevent
overload, nongenuine parts or parts not designed for this vehicle may be
unusable.
WARNING
■ To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure to do so may cause damage to the vehicle, and possibly a fire or
injury.
● Never use a fuse of a higher amperage rating than that indicated, or use
any other object in place of a fuse.
● Always use a genuine Toyota fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
● Do not modify the fuses or fuse boxes.
NOTICE
■ Before replacing fuses
Have the cause of electrical overload determined and repaired by your
Toyota dealer as soon as possible.

WARNING
■ Replacing light bulbs
● Be sure to stop the hybrid system and turn off the lights. Do not attempt to
replace the bulb immediately after turning off the lights.
The bulbs become very hot and may cause burns.
● Do not touch the glass portion of the light bulb with bare hands. When it is
unavoidable to hold the glass portion, use and hold with a clean dry cloth
to avoid getting moisture and oils on the bulb.
Also, if the bulb is scratched or dropped, it may blow out or crack.
● Fully install light bulbs and any parts used to secure them. Failure to do so
may result in heat damage, fire, or water entering the light unit. This may
damage the back-up lights or cause condensation to build up on the lens.
● Do not attempt to repair or disassemble light bulbs, connectors, electric
circuits or component parts.
Doing so may result in death or serious injury due to electric shock.
● Do not replace the right-hand back-up light immediately after the vehicle
has been driven.
After the vehicle has been driven the exhaust pipe will be extremely hot,
and touching the exhaust pipe may result in burns.
● Use gloves and other protection to prevent injuries on vehicle parts.
There is the danger of being injured on the edges of parts.
■ To prevent damage or fire
● Make sure bulbs are fully seated and locked.
● Check the wattage of the bulb before installing to prevent heat damage.

■ Electric power steering system warning light (warning buzzer)
When the 12-volt battery charge becomes insufficient or the voltage tempo-
rarily drops, the electric power steering system warning light may come on
and the warning buzzer may sound.
■ If the malfunction indicator lamp comes on while driving
First check the following:
● Is the fuel tank empty?
If it is, fill the fuel tank immediately.
● Is the fuel tank cap loose?
If it is, tighten it securely.
The malfunction indicator lamp will go off after several driving trips.
If the malfunction indicator lamp does not go off even after several trips, con-
tact your Toyota dealer as soon as possible.
■
When the tire pressure warning light comes on
Inspect the appearance of the tire to check that the tire is not punctured.
If the tire is punctured: P. 680
If the tire is not punctured:
Check the tire inflation pressure and adjust to the appropriate level. Initial-
izing the tire pressure warning system will not turn off the tire pressure
warning light.
■ The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such
as natural air leaks and tire inflation pressure changes caused by tem-
perature. In this case, adjusting the tire inflation pressure will turn off the
warning light (after a few minutes).

■ If the tire pressure warning light frequently comes on after blinking
for 1 minute
If the tire pressure warning light frequently comes on after blinking for
1 minute when the power switch is turned to ON mode, have it checked
by your Toyota dealer.
■ Warning buzzer
In some cases, the buzzer may not be heard due to being in a noisy location
or audio sound.
WARNING
■ When the electric power steering system warning light comes on
When the light comes on yellow, the assist to the power steering is
restricted. When the light comes on red, the assist to the power steering is
lost and handling operations of the steering wheel become extremely
heavy. When steering wheel operations are heavier than usual, grip the
steering wheel firmly and operate it using more force than usual.
■
If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could
cause a loss of vehicle control and result in death or serious injury.
● Stop your vehicle in a safe place as soon as possible. Adjust the tire
inflation pressure immediately.
● If the tire pressure warning light comes on even after tire inflation pres-
sure adjustment, it is probable that you have a flat tire. Check the tires.
If a tire is flat, repair the flat tire by using emergency tire puncture
repair kit.
● Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate,
you could lose control of the steering wheel or the brakes.
■ If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.

WARNING
■ Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pressure
label (tire and load information label). (If your vehicle has tires of a dif-
ferent size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine
the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS-tire pressure warning system) that
illuminates a low tire pressure telltale (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressure telltale (tire pressure warning light) illumi-
nates, you should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-inflation has not reached
the level to trigger illumination of the TPMS low tire pressure telltale (tire
pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warn-
ing system) malfunction indicator to indicate when the system is not
operating properly. The TPMS (tire pressure warning system) malfunc-
tion indicator is combined with the low tire pressure telltale (tire pressure
warning light). When the system detects a malfunction, the telltale will
flash for approximately one minute and then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle start-ups
as long as the malfunction exists. When the malfunction indicator is illu-
minated, the system may not be able to detect or signal low tire pres-
sure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a vari-
ety of reasons, including the installation of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure warning
system) from functioning properly. Always check the TPMS (tire pres-
sure warning system) malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS (tire pressure warning system) to
continue to function properly.

If you have a flat tire
Your vehicle is not equipped with a spare tire, but instead is
equipped with an emergency tire puncture repair kit.
A puncture caused by a nail or screw passing through the tire
tread can be repaired temporarily using the emergency tire
puncture repair kit. (The kit contains a bottle of sealant. The
sealant can be used only once to temporarily repair one tire
without removing the nail or screw from the tire.) After temporar-
ily repairing the tire with the kit, have the tire repaired or
replaced by your Toyota dealer.

kit impossible.
• To avoid sealant leakage, move the vehicle until the area of the
puncture, if known, is positioned at the top of the tire.
■ A flat tire that cannot be repaired with the emergency tire puncture
repair kit
In the following cases, the tire cannot be repaired with the emergency tire
puncture repair kit. Contact your Toyota dealer.
● When the tire is damaged due to driving without sufficient air pressure
● When there are any cracks or damage at any location on the tire, such
as on the side wall, except the tread
● When the tire is visibly separated from the wheel
● When the cut or damage to the tread is 0.16 in. (4 mm) long or more
● When the wheel is damaged
● When two or more tires have been punctured
● When more than one sharp objects such as nails or screws have passed

Emergency tire puncture repair kit
● The emergency tire puncture repair kit is for filling the car tire with air.
● The sealant has a limited life span. The expiry date is marked on the
bottle. The sealant should be replaced before the expiry date. Contact
your Toyota dealer for replacement.
● The sealant stored in the emergency tire puncture repair kit can be used
only once to temporarily repair a single tire. If the sealant in the bottle
and other parts of the kit have been used and need to be replaced, con-
tact your Toyota dealer.
● The compressor can be used repeatedly.
● The sealant can be used when the outside temperature is from -40°F
(-40°C) to 140°F (60°C).
● The kit is exclusively designed for size and type of tires originally
installed on your vehicle. Do not use it for tires that a different size than
the original ones, or for any other purposes.
● If the sealant gets on your clothes, it may stain.
● If the sealant adheres to a wheel or the surface of the vehicle body, the
stain may not be removable if it is not cleaned at once. Immediately wipe
away the sealant with a wet cloth.
● During operation of the repair kit, a loud operation noise is produced.
This does not indicate a malfunction.
● Do not use to check or to adjust the tire pressure.

When trouble arises
WARNING
■ Do not drive the vehicle with a flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the
wheel beyond repair.
Driving with a flat tire may cause a circumferential groove on the side
wall. In such a case, the tire may explode when using a repair kit.
■ Caution while driving
● Store the repair kit in the luggage compartment.
Injuries may result in the event of an accident or sudden braking.
● The repair kit is exclusively only for your vehicle.
Do not use repair kit on other vehicles, which could lead to an accident
causing death or serious injury.
● Do not use repair kit for tires that are different size than the original
ones, or for any other purpose. If the tires have not been completely
repaired, it could lead to an accident causing death or serious injury.
■ Precautions for use of the sealant
● Ingesting the sealant is hazardous to your health. If you ingest sealant,
consume as much water as possible, and then immediately consult a
doctor.
● If sealant gets in eyes or adheres to skin, immediately wash it off with
water. If discomfort persists, consult a doctor.

PRIUS PRIME_OM_OM47C77U_(U)
WARNING
■ When fixing the flat tire
● Stop your vehicle in a safe and flat area.
● Do not touch the wheels or the area around the brakes immediately
after the vehicle has been driven.
After the vehicle has been driven, the wheels and the area around the
brakes may be extremely hot. Touching these areas with hands, feet or
other body parts may result in burns.
● Connect the valve and hose securely with the tire installed on the vehi-
cle. If the hose is not properly connected to the valve, air leakage may
occur as sealant may be sprayed out.
● If the hose comes off the valve while inflating the tire, there is a risk
that the hose will move abruptly due to air pressure.
● After inflation of the tire has completed, the sealant may splatter when
the hose is disconnected or some air is let out of the tire.
● Follow the operation procedure to repair the tire. If the procedures not
followed, the sealant may spray out.
● Keep back from the tire while it is being repaired, as there is a chance
of it bursting while the repair operation is being performed. If you
notice any cracks or deformation of the tire, turn off the compressor
switch and stop the repair operation immediately.
● The repair kit may overheat if operated for a long period of time. Do not
operate the repair kit continuously for more than 40 minutes.
● Parts of the repair kit become hot during operation. Be careful handling
the repair kit during and after operation. Do not touch the metal part
connecting the bottle and the compressor. It will be extremely hot.
● Do not attach the vehicle speed warning sticker to an area other than
the one indicated. If the sticker is attached to an area where an SRS
airbag is located, such as the pad of the steering wheel, it may prevent
the SRS airbag from operating properly.

WARNING
■ Driving to spread the liquid sealant evenly
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death
or serious injury.
● Drive the vehicle carefully at a low speed. Be especially careful when
turning and cornering.
● If the vehicle does not drive straight or you feel a pull through the
steering wheel, stop the vehicle and check the following.
• Tire condition. The tire may have separated from the wheel.
• Tire inflation pressure. If the tire inflation pressure is 19 psi
(130 kPa, 1.3 kgf/cm
2
or bar) or less, the tire may be severely dam-
aged.
NOTICE
■ When performing an emergency repair
● A tire should only be repaired with the emergency tire puncture repair
kit if the damage is caused by a sharp object such as nail or screw
passing through the tire tread.
Do not remove the sharp object from the tire. Removing the object may
widen the opening and disenable emergency repair with the repair kit.
● The repair kit is not waterproof. Make sure that the repair kit is not
exposed to water, such as when it is being used in the rain.
● Do not put the repair kit directly onto dusty ground such as sand at the
side of the road. If the repair kit vacuums up dust etc., a malfunction
may occur.
■ Precautions for the emergency tire puncture repair kit
● The repair kit power source should be 12 V DC suitable for vehicle
use. Do not connect the repair kit to any other source.
● If fuel splatters on the repair kit, the repair kit may deteriorate. Take
care not to allow fuel to contact it.
● Place the repair kit in a storage to prevent it from being exposed to dirt
or water.
● Store the repair kit in the luggage compartment out of reach of chil-
dren.
● Do not disassemble or modify the repair kit. Do not subject parts such
as the air pressure indicator to impacts. This may cause a malfunction.

■ Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
■ To prevent 12-volt battery discharge
● Turn off the headlights and the audio system while the hybrid system is off.
● Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic.
■ When the 12-volt battery is removed or discharged
● Information stored in the ECU is cleared. When the 12-volt battery is
depleted, have the vehicle inspected at your Toyota dealer.
● Some systems may require initialization. (P. 752)
■ When removing the 12-volt battery terminals
When the 12-volt battery terminals are removed, the information stored in the
ECU is cleared. Before removing the 12-volt battery terminals, contact your
Toyota dealer.
■ Charging the 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even when
the vehicle is not in use, due to natural discharge and the draining effects of
certain electrical appliances. If the vehicle is left for a long time, the 12-volt
battery may discharge, and the hybrid system may be unable to start. (The
12-volt battery recharges automatically while the hybrid system is operating.)
706
8-2. Steps to take in an emergency
PRIUS PRIME_OM_OM47C77U_(U)
■ When recharging or replacing the 12-volt battery
● In some cases, it may not be possible to unlock the doors using the smart
key system when the 12-volt battery is discharged. Use the wireless remote
control or the mechanical key to lock or unlock the doors.
● The hybrid system may not start on the first attempt after the 12-volt battery
has recharged but will start normally after the second attempt. This is not a
malfunction.
● Vehicles with smart lid & connector locking system:
It may be impossible to unlock the charging port lid or locking and unlocking
the charging connector immediately after the 12-volt battery is reconnected.
In this case, carry the electronic key on your person and operate the
charging port lid or charging connector lock switch again.
● The power switch mode is memorized by the vehicle. When the 12-volt bat-
tery is reconnected, the system will return to the mode it was in before the
12-volt battery was discharged. Before disconnecting the 12-volt battery,
turn the power switch off.
If you are unsure what mode the power switch was in before the 12-volt bat-
tery discharged, be especially careful when reconnecting the 12-volt battery.
● If the 12-volt battery discharges while the shift position is in P, it may not be
possible to shift the shift position to other positions. In this case, the vehicle
cannot be towed without lifting both front wheels because the front wheels
will be locked. (P. 655)
■ When replacing the 12-volt battery
● Use a 12-volt battery that conforms to European regulations.
● Use a 12-volt battery that the case size is same as the previous one (LN1),
20 hour rate capacity (20HR) is equivalent (45Ah) or greater, and perfor-
mance rating (CCA) is equivalent (295A) or greater.
• If the sizes differ, the 12-volt battery cannot be properly secured.
• If the 20 hour rate capacity is low, even if the time period where the vehi-
cle is not used is a short time, the 12-volt battery may discharge and the
hybrid system may not be able to start.
● For details, consult your Toyota dealer.

and death or serious injury.
■ Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the 12-volt battery:
● Make sure each jumper cable is connected to the correct terminal and that
it is not unintentionally in contact with any other than the intended terminal.
● Do not allow the other end of the jumper cable connected to the “+” termi-
nal to come into contact with any other parts or metal surfaces in the area,
such as brackets or unpainted metal.
● Do not allow the + and - clamps of the jumper cables to come into contact
with each other.
● Do not smoke, use matches, cigarette lighters or allow open flame near
the 12-volt battery.
■ 12-volt battery precautions
The 12-volt battery contains poisonous and corrosive acidic electrolyte,
while related parts contain lead and lead compounds. Observe the following
precautions when handling the 12-volt battery:
● When working with the 12-volt battery, always wear safety glasses and
take care not to allow any battery fluids (acid) to come into contact with
skin, clothing or the vehicle body.

Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to satisfy
the following grade and viscosity.
Oil grade: API SN/RC multigrade engine oil
Recommended viscosity: SAE 0W-16
SAE 0W-16 is the best choice
for good fuel economy and
good starting in cold weather.
If SAE 0W-16 is not available,
SAE 0W-20 oil may be used.
However, it must be replaced
with SAE 0W-16 at the next oil
change.
Oil viscosity (0W-16 is explained here as an example):
• The 0W in 0W-16 indicates the characteristic of the oil which
allows cold startability. Oils with a lower value before the W allow
for easier starting of the engine in cold weather.
• The 16 in 0W-16 indicates the viscosity characteristic of the oil
when the oil is at high temperature. An oil with a higher viscosity
(one with a higher value) may be better suited if the vehicle is
operated at high speeds, or under extreme load conditions.

Fuel information
■ Gasoline quality
In very few cases, driveability problems may be caused by the brand of gaso-
line you are using. If driveability problems persist, try changing the brand of
gasoline. If this does not correct the problem, consult your Toyota dealer.
■ Recommendation of the use of gasoline containing detergent additives
● Toyota recommends the use of gasoline that contains detergent additives to
avoid the build-up of engine deposits.
● All gasoline sold in the U.S.A. contains minimum detergent additives to
clean and/or keep clean intake systems, per EPA’s lowest additives concen-
tration program.
● Toyota strongly recommends the use of Top Tier Detergent Gasoline. For
more information on Top Tier Detergent Gasoline and a list of marketers,
please go to the official website www.toptiergas.com.
You must only use unleaded gasoline.
Select octane rating 87 (Research Octane Number 91) or higher.
Use of unleaded gasoline with an octane rating lower than 87
may result in engine knocking. Persistent knocking can lead to
engine damage.
At minimum, the gasoline you use should meet the specifications of
ASTM D4814 in the U.S.A..

■ Recommendation of the use of low emissions gasoline
Gasolines containing oxygenates such as ethers and ethanol, as well as
reformulated gasolines, are available in some cities. These fuels are typically
acceptable for use, providing they meet other fuel requirements.
Toyota recommends these fuels, since the formulations allow for reduced
vehicle emissions.
■ Non-recommendation of the use of blended gasoline
● If you use gasohol in your vehicle, be sure that it has an octane rating no
lower than 87.
● Toyota does not recommend the use of gasoline containing methanol.
■ Non-recommendation of the use of gasoline containing MMT
Some gasoline contains an octane enhancing additive called MMT
(Methylcyclopentadienyl Manganese Tricarbonyl).
Toyota does not recommend the use of gasoline that contains MMT. If fuel
containing MMT is used, your emission control system may be adversely
affected.
The malfunction indicator lamp on the instrument cluster may come on. If this
happens, contact your Toyota dealer for service.
■ If your engine knocks
● Consult your Toyota dealer.
● You may occasionally notice light knocking for a short time while accelerat-
ing or driving uphill. This is normal and there is no need for concern.
● Use only gasoline containing up to 15%
ethanol.
DO NOT use any flex-fuel or gasoline
that could contain more than 15% etha-
nol, including from any pump labeled
E30, E50, E85 (which are only some
examples of fuel containing more than
15% ethanol).
DO NOT use gasoline
containing more than
15% ethanol.

NOTICE
■ Notice on fuel quality
● Do not use improper fuels. If improper fuels are used, the engine will be
damaged.
● Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three-way catalytic
converters causing the emission control system to malfunction.
● Do not use gasohol other than the type previously stated.
Other gasohol may cause fuel system damage or vehicle performance
problems.
● Using unleaded gasoline with an octane number or rating lower than the
level previously stated will cause persistent heavy knocking.
At worst, this will lead to engine damage.
■ Fuel-related poor driveability
If poor driveability (poor hot starting, vaporization, engine knocking, etc.) is
encountered after using a different type of fuel, discontinue the use of that
type of fuel.
■ When refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle’s paint.

This information has been prepared in accordance with regulations
issued by the National Highway Traffic Safety Administration of the
U.S. Department of Transportation.
It provides the purchasers and/or prospective purchasers of Toyota
vehicles with information on uniform tire quality grading.
Your Toyota dealer will help answer any questions you may have as
you read this information.
■ DOT quality grades
All passenger vehicle tires must conform to Federal Safety Require-
ments in addition to these grades. Quality grades can be found
where applicable on the tire sidewall between tread shoulder and
maximum section width.
For example: Treadwear 200 Traction AA Temperature A
■ Treadwear
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a speci-
fied government test course.
For example, a tire graded 150 would wear one and a half (1 - 1/2)
times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual condi-
tions of their use. Performance may differ significantly from the norm
due to variations in driving habits, service practices and differences
in road characteristics and climate.
■ Traction AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B and C,
and they represent the tire’s ability to stop on wet pavement as
measured under controlled conditions on specified government test
surfaces of asphalt and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on braking
(straight ahead) traction tests and does not include cornering (turn-
ing) traction.
Uniform Tire Quality Grading
734
PRIUS PRIME_OM_OM47C77U_(U)
9-1. Specifications
■ Temperature A, B, C
The temperature grades are A (the highest), B, and C, representing
the tire’s resistance to the generation of heat and its ability to dissi-
pate heat when tested under controlled conditions on a specified
indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure.
Grade C corresponds to a level of performance which all passenger
car tires must meet under the Federal Motor Vehicle Safety Stan-
dard No. 109.
Grades B and A represent higher levels of performance on the labo-
ratory test wheel than the minimum required by law.
Warning: The temperature grades of a tire assume that it is properly
inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either sepa-
rately or in combination, can cause heat buildup and possible tire
failure.

WARNING
■ Cautions during customization
As the hybrid system needs to be operating during customization, ensure
that the vehicle is parked in a place with adequate ventilation. In a closed
area such as a garage, exhaust gases including harmful carbon monoxide
(CO) may collect and enter the vehicle. This may lead to death or a serious
health hazard.
NOTICE
■ During customization
To prevent 12-volt battery discharge, ensure that the hybrid system is oper-
ating while customizing features.

Votre véhicule est doté de COUSSINS GONFLABLES ÉVOLUÉS
dont la conception s’appuie sur les normes de sécurité des véhicules
à moteur américains (FMVSS208). Le module de capteur de coussin
gonflable (ECU) contrôle le déploiement des coussins gonflables en
fonction des informations obtenues des capteurs et d’autres éléments
affichés dans le diagramme des composants du système ci-dessus.
Ces informations comprennent des données relatives à la gravité de
l’accident et aux occupants. Au moment du déploiement des coussins
gonflables, une réaction chimique se produit dans les gonfleurs de
coussin gonflable et les coussins gonflables se remplissent rapide-
ment d’un gaz non toxique pour aider à limiter le mouvement des
occupants.

AVERTISSEMENT
■ Précautions relatives aux coussins gonflables SRS
Observez les précautions suivantes en ce qui concerne les coussins gon-
flables SRS.
Les négliger pourrait occasionner des blessures graves, voire mortelles.
● Le conducteur et tous les passagers du véhicule doivent porter leur cein-
ture de sécurité de la manière appropriée.
Les coussins gonflables SRS sont des dispositifs supplémentaires qui
doivent être utilisés avec les ceintures de sécurité.
● Le coussin gonflable SRS du conducteur se déploie avec une force consi-
dérable et peut occasionner des blessures graves, voire mortelles, notam-
ment lorsque le conducteur se trouve très près du coussin gonflable. La
National Highway Traffic Safety Administration (NHTSA), aux États-Unis,
fait les recommandations suivantes :
La zone à risque du coussin gonflable du conducteur couvre 2 à 3 in. (50
à 75 mm) de la zone de déploiement du coussin gonflable. Pour assurer
une marge de sécurité suffisante, restez à 10 in. (250 mm) du coussin
gonflable. Cette distance est mesurée depuis le centre du volant jusqu’à
votre sternum. Si maintenant vous vous tenez assis à moins de 10 in.
(250 mm), vous pouvez changer votre position de conduite de plusieurs
manières :
• Reculez votre siège à la position maximale vous permettant d’atteindre
encore aisément les pédales.
• Inclinez légèrement le dossier du siège. Bien que les véhicules soient
conçus différemment, la plupart des conducteurs peuvent maintenir une
distance de 10 in. (250 mm), même si leur siège se trouve complète-
ment vers l’avant, simplement en inclinant un peu le dossier du siège
vers l’arrière. Si la visibilité avant est moindre après avoir incliné le dos-
sier de votre siège, utilisez un coussin ferme et non glissant pour être
assis plus haut ou relevez le siège si cette option est disponible sur
votre véhicule.
• Si votre volant est réglable en hauteur, inclinez-le vers le bas. Cela
vous permet d’orienter le coussin gonflable vers votre buste plutôt que
vers votre tête et vers votre cou.
Le siège doit être réglé de la manière recommandée ci-dessus par la
NHTSA, tout en gardant le contrôle des pédales et du volant, ainsi que la
vue sur les commandes du tableau de bord.
762
PRIUS PRIME_OM_OM47C77U_(U)
AVERTISSEMENT
■ Précautions relatives aux coussins gonflables SRS
● Le coussin gonflable SRS du passager avant se déploie également avec
une force considérable et peut occasionner des blessures graves, voire
mortelles, notamment lorsque le passager avant se trouve très près du
coussin gonflable. Le siège du passager avant doit se trouver le plus loin
possible du coussin gonflable et le dossier doit être réglé de manière à ce
que le passager avant soit assis bien droit.
● Le déploiement d’un coussin gonflable risque d’infliger des blessures
graves, voire mortelles, aux bébés et aux enfants mal assis et/ou mal atta-
chés. Un bébé ou un enfant trop petit pour utiliser une ceinture de sécurité
doit être correctement retenu à l’aide d’un dispositif de retenue pour
enfants. Toyota recommande vivement de placer et d’attacher correcte-
ment tous les bébés et tous les enfants sur les sièges arrière du véhicule à
l’aide de dispositifs de retenue adaptés. Les sièges arrière sont plus sécu-
ritaires pour les bébés et les enfants que le siège du passager avant.
● N’installez jamais un dispositif de retenue pour enfants de type dos à la
route sur le siège du passager avant, même si le voyant “AIR BAG OFF”
est allumé. En cas d’accident, la force et la vitesse de déploiement du
coussin gonflable du passager avant pourraient infliger à l’enfant des bles-
sures graves, voire mortelles, si le dispositif de retenue pour enfants de
type dos à la route était installé sur le siège du passager avant.
● Si la rallonge de ceinture de sécurité a
été reliée à la boucle des ceintures de
sécurité des sièges avant sans avoir
aussi été attachée à la plaque de blo-
cage des ceintures de sécurité, les
coussins gonflables SRS avant consi-
déreront que le conducteur et le passa-
ger avant portent tout de même leur
ceinture de sécurité même si les cein-
tures de sécurité ne sont pas attachées.
Les coussins gonflables SRS avant
peuvent alors ne pas s’activer correcte-
ment lors d’une collision, ce qui pourrait
occasionner des blessures graves,
voire mortelles, en cas de collision.
Assurez-vous de toujours porter la cein-
ture de sécurité avec la rallonge de
ceinture de sécurité.

■ Précautions relatives aux coussins gonflables SRS
● Ne vous asseyez pas sur le bord du
siège et ne vous appuyez pas sur la
planche de bord.
● Ne laissez pas un enfant se tenir face
au coussin gonflable SRS du passager
avant ni s’asseoir sur les genoux d’un
passager avant.
● Ne laissez pas les occupants des
sièges avant tenir des objets sur leurs
genoux.
● Ne vous appuyez pas sur la portière ou
sur le brancard de pavillon, ni sur les
montants avant, latéraux ou arrière.
● Ne laissez personne s’agenouiller face

■ Précautions relatives aux coussins gonflables SRS
● N’accrochez pas de cintres ni d’autres objets rigides sur les crochets
porte-vêtements. Tous ces objets pourraient se transformer en projectiles
et vous occasionner des blessures graves, voire mortelles, en cas de
déploiement des coussins gonflables SRS en rideau.
● Si un recouvrement de vinyle est placé sur la zone de déploiement du
coussin gonflable SRS de protection des genoux, veillez à le retirer.
● N’utilisez pas d’accessoires recouvrant les parties du siège où les cous-
sins gonflables SRS latéraux et le coussin gonflable SRS du coussin de
siège se déploient, car ces accessoires pourraient entraver le déploiement
des coussins SRS. De tels accessoires peuvent empêcher les coussins
gonflables latéraux et le coussin gonflable du coussin de siège de se
déployer correctement, rendre le système inopérant ou provoquer acci-
dentellement le déploiement des coussins gonflables latéraux et du cous-
sin gonflable du coussin de siège, occasionnant des blessures graves,
voire mortelles.
● Ne frappez pas et n’appliquez pas une pression importante à l’emplace-
ment des portières avant ou des composants des coussins gonflables
SRS.
Cela peut provoquer un mauvais fonctionnement des coussins gonflables
SRS.
● Ne touchez à aucun composant des coussins gonflables SRS immédiate-
ment après leur déploiement (gonflage), car ils pourraient être chauds.
● Ne fixez et n’appuyez rien sur des
zones telles que la planche de bord, le
tampon de volant ou encore la partie
inférieure du tableau de bord.
Ces objets peuvent se transformer en
projectiles lorsque les coussins gon-
flables SRS du conducteur, du passa-
ger avant et de protection des genoux
se déploient.
● Ne fixez rien sur des zones telles que
les portières, le pare-brise, les glaces
latérales, les montants avant ou arrière,
le brancard de pavillon et la poignée de
maintien.

AVERTISSEMENT
■ Précautions relatives aux coussins gonflables SRS
● Si vous avez de la difficulté à respirer après le déploiement des coussins
gonflables SRS, ouvrez une portière ou une glace latérale pour laisser
entrer l’air frais, ou quittez le véhicule si vous pouvez le faire en toute
sécurité. Dès que possible, nettoyez tous les résidus afin d’éviter les irrita-
tions cutanées.
● Si les emplacements de stockage des coussins gonflables SRS, tels que
le tampon de volant et les garnitures des montants avant et arrière, sont
endommagés ou fissurés, faites-les remplacer par votre concessionnaire
Toyota.
● Ne placez aucun objet, par exemple un coussin, sur le siège du passager
avant. Cela disperserait le poids du passager, ce qui empêcherait le cap-
teur de le détecter correctement. Cela pourrait empêcher le déploiement
des coussins gonflables SRS du passager avant en cas de collision.
■ Modification et mise au rebut des composants du système de coussins
gonflables SRS
Ne mettez pas votre véhicule au rebut et n’effectuez aucune des modifica-
tions suivantes sans d’abord consulter votre concessionnaire Toyota. Les
coussins gonflables SRS pourraient fonctionner de manière incorrecte ou
se déployer (gonfler) accidentellement, ce qui serait susceptible d’occasion-
ner des blessures graves, voire mortelles.
● Installation, retrait, démontage et réparation des coussins gonflables SRS
● Réparations, modifications, retrait ou remplacement du volant, du tableau
de bord, de la planche de bord, des sièges ou du capitonnage des sièges,
des montants avant, latéraux et arrière, des brancards de pavillon, des
panneaux des portières avant, des garnitures des portières avant ou des
hautparleurs des portières avant
● Modifications du panneau de la portière avant (comme le perforer)
● Réparations ou modifications de l’aile avant, du pare-chocs avant ou du

● Installation d’une protection de calandre (barre safari, barre kangourou,
etc.), de lames de déneigement, de treuils ou d’un porte-bagages de toit
● Modifications du système de suspension du véhicule
● Installation d’appareils électroniques tels qu’un émetteur-récepteur radio
