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 engine 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:
Multiport fuel injection system/sequential multiport fuel injection system
Anti-lock brake system
SRS airbag system
Seat belt pretensioner system
Toyota Safety Sense P
Be sure to check with your Toyota dealer for precautionary measures or spe-
cial instructions regarding installation of a mobile two-way radio system.

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 front camera (available only when certain safety sys-
tems are activated, which varies depending on the vehicle specifica-
tions).
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 this computer 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.
Scrapping of your Toyota
Perchlorate Material
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
vehicle. 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, the moon roof, 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 cause the driver’s floor mat to slip, possibly interfering
with the pedals while driving. An unexpectedly high speed may result or it may
become difficult to stop the vehicle. This could lead to an accident, resulting in
death or serious injury.
When installing the driver’s floor mat
Do not use floor mats designed for other models or different model year
vehicles, even if they are Toyota Genuine floor mats.
Only use floor mats designed for the driver’s seat.
Always install the floor mat securely using the retaining hooks (clips) pro-
vided.
Do not use two or more floor mats on top of each other.
Do not place the floor mat bottom-side up or upside-down.
Before driving

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.

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. (P. 62)
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. 5 8)
When the child becomes large enough to properly wear the vehicle’s seat
belt, follow the instructions regarding seat belt usage. (P. 3 0 )
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 severe 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.
Always wear the belt with the shoulder portion over the outside armrest
and the lap portion under the outside armrest.
Pregnant women
People suffering illness
Obtain medical advice and wear the seat belt in the proper way. (P. 3 0 )
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 a pregnant woman, but also the
fetus could suffer death or serious injury
as a result of sudden braking or a colli-
sion.

WARNING
When children are in the vehicle
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 injuries
that could result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used
to cut the belt.
Seat belt pretensioners (front seats)
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.
Adjustable shoulder anchor (front and second outside Tip-up seats)
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. 3 3)
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.

WARNING
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.
When using the third center seat belt
NOTICE
When using a seat belt extender
When releasing the seat belt, press on the buckle release button on the
extender, not on the seat belt.
This helps prevent damage to the vehicle interior and the extender itself.
Do not use the third center seat belt with
either buckle released. Fastening only
one of the buckles may result in death or
serious injury in case of sudden braking,
sudden swerving or an accident.

For safety and security
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
airbag toward your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA above, while

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
airbag 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
system. 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.

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

WARNING
SRS airbag precautions
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 driver’s knee airbags deploy.
Do not attach anything to areas such as
a door, windshield glass, side door
glass, front or rear pillar, roof side rail
and assist grip.
Vehicles without a smart key system:
Do not attach any heavy, sharp or hard
objects such as keys and accessories
to the key. The objects may restrict the
SRS knee airbag inflation or be thrust
into the driver’s seat area by the force
of the deploying airbag, thus causing a
danger.

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
airbags and seat cushion airbag from activating correctly, disable the
system or cause the side airbags and seat cushion airbag to inflate acci-
dentally, resulting in death or serious injury.
Do not strike or apply significant levels of force to the area of the SRS
airbag components.
Doing so can cause the SRS airbags to malfunction.
Do not touch any of the component parts immediately after the SRS
airbags have deployed (inflated) as they may be hot.
If breathing becomes difficult after the SRS airbags have deployed, open a
door or 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,

For safety and security
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.
Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
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 rail,
may be hot for several minutes. The airbag itself may also be hot.
The windshield may crack.
For Safety Connect subscribers, if the SRS airbags deploy or in the event of
a severe rear-end collision, the system is designed to send an emergency
call to the response center, notifying them of the vehicle’s location (without
needing to push the “SOS” button) 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. 385)
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 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. (P. 5 2 )
The SRS seat cushion airbag on the front passenger’s 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]).
The SRS curtain shield airbags will deploy in the event of vehicle rollover.
The SRS side and 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 side and 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 airbag (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.
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
rear collision, if it rolls over, or if it is involved in a low-speed side collision or
low-speed frontal collision.

WARNING
Front passenger occupant classification system precautions
Observe the following precautions regarding the front passenger occupant
classification system.
Failure to do so may cause death or serious injury.
Wear the seat belt properly.
Make sure the front passengers 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 or armrest).
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.

WARNING
Front passenger occupant classification system precautions
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.
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. 62)
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.

Safety information for 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 sliding door child-protector lock or the window lock switch
to avoid children opening the door while driving or operating the
power window accidentally. (P. 125, 184)
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
vehicle.
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 windows, the moon roof (if equipped) or other features of the vehicle. In
addition, heat build-up or extremely cold temperatures inside the vehicle
can be fatal to children.

Child restraint systems
Studies have shown that installing a child restraint system on a rear
seat is much safer than installing one on the front passenger seat.
Choose a child restraint system that suits your vehicle and is appro-
priate to the age and size of the child.
For installation details, follow the instructions provided with the child
restraint system.
General installation instructions are provided in this manual.
(P. 62)
A child restraint system for a small child or baby must itself be
properly restrained on the seat with the LATCH anchors or the
lap portion of the lap/shoulder belt.
The laws of all 50 states of U.S.A. and Canada now require the
use of child restraint systems.

Child restraint systems are classified into the following 3 types
according to the age and size of the child:
Selecting an appropriate child restraint system
Use a child restraint system appropriate for the child until the child becomes
large enough to properly wear the vehicle’s seat belt.
If the child is too large for a child restraint system, sit the child on a rear seat
and use the vehicle’s seat belt. (P. 30 )

WARNING
Child restraint precautions
For effective protection in automobile accidents and sudden stops, a child
must be properly restrained, using a seat belt or child restraint system
depending on the age and size of the child. Holding a child in your arms is
not a substitute for a child restraint system. In an accident, the child can be
crushed against the windshield, or between you and the vehicle’s interior.
Toyota strongly urges the use of a proper child restraint system that con-
forms to the size of the child, installed on the rear seat. According to acci-
dent statistics, the child is safer when properly restrained in the rear seat
than in the front seat.
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.
Adjust the seatback as upright as possible and always move the seat as
far back as possible even if the “AIR BAG OFF” indicator light is illumi-
nated, because the front passenger airbag could inflate with considerable
speed and force. Otherwise, the child may be killed or seriously injured.
Do not use the seat belt extender when installing a child restraint system
on the front or rear passenger seat. If installing a child restraint system
with the seat belt extender connected to the seat belt, the seat belt will not
securely hold the child restraint system, which could cause death or seri-
ous injury to the child or other passengers in the event of a sudden stop,
sudden swerve or an accident.

WARNING
Child restraint precautions
Do not allow the child to lean his/her head or any part of his/her body
against the side door or the area of the seat, front and side pillars or roof
side rail from which the SRS side airbags or 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.
Make sure you have complied with all installation instructions provided by
the child restraint manufacturer and that the system is properly secured. If
it is not secured properly, it may cause death or serious injury to the child
in the event of a sudden stop, sudden swerve or an accident.
When children are in the vehicle
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 injuries
that could result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used
to cut the belt.
When the child restraint system is not in use
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 passenger com-
partment.
If it is necessary to detach the child restraint system, remove it from the
vehicle or store it securely in the luggage compartment. This will prevent it
from injuring passengers in the event of a sudden stop, sudden swerve or
an accident.

Laws and regulations pertaining to anchorages
The LATCH system conforms to FMVSS225 or CMVSS210.2.
Child restraint systems conforming to FMVSS213 or CMVSS213 specifica-
tions can be used.
This vehicle is designed to conform to the SAE J1819.
WARNING
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. 34)
When installing a child restraint system
Follow the directions given in the child restraint system installation manual
and fix the child restraint system securely in place.
If the child restraint system is not correctly 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 driver’s seat interferes with the
child restraint system and prevents it
from being attached correctly, attach the
child restraint system to the right-hand
rear seat.
Adjust the front passenger seat or sec-
ond seats so that it does not interfere
with the child restraint system.
Only put a forward-facing child restraint
system on the front seat when unavoid-
able. When installing a forward-facing
child restraint system on the front pas-
senger seat, move the seat as far back
as possible even if the “AIR BAG OFF”
indicator light is illuminated. Failure to
do so may result in death or serious
injury if the airbags deploy (inflate).

WARNING
When installing a child restraint system
When installing a child restraint system on the third center seat, adjust
both seatbacks at the same angle. Otherwise, the child restraint system
cannot be securely restrained and this may cause death or serious injuries
in the event of sudden braking, sudden swerving or an accident.
When using the LATCH anchors for a child restraint system, move the seat
as far back as possible (second seat only), with the seatback close to the
child restraint system.
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. Failing to do so may result in death or serious injury in the event
of sudden braking, sudden swerving or an accident.
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.
Follow all installation instructions provided by the child restraint system
manufacturer.
When securing some types of child restraint systems in second (8-passen-
ger models) or third row 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 dose 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.

WARNING
When installing a child restraint system to the AUTO ACCESS SEAT
(if equipped)
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.
To correctly attach a child restraint system to the anchors
When using the LATCH anchors, be sure that there are no foreign objects
around the anchors and that the seat belt is not caught behind the child
restraint system. Make sure the child restraint system is securely attached,
or it may cause death or serious injury to the child or other passengers in
the event of a sudden braking, sudden swerving or an accident.
Do not operate the AUTO ACCESS
SEAT while a child restraint system is
fixed to the seat by the child restraint
lock function belt.
If you force the seat operation, the seat,
seat belt or child restraint system may
be damaged, or may cause an injury.
If a child restraint system is fixed to the
AUTO ACCESS SEAT by the LATCH
system, be careful that the child’s head,
hands and legs do not hit the body of
the vehicle when operating the seat.
Injuries may be caused.

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 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 engine.
Do not leave the vehicle with the engine 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 engine running in an area with snow build-up, or where it
is snowing. If snowbanks build up around the vehicle while the engine is
running, exhaust gases may collect and enter the vehicle.
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.

WARNING
The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal
information display. At extremely low temperatures, the display monitor may
respond slowly, and display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear
number appearing on the display. This lag could cause the driver to
downshift again, causing rapid and excessive engine braking and possibly
an accident resulting in death or injury.
Cautions during setting up the display
As the engine needs to be running during setting up the display, 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 setting up the display
To prevent battery discharge, ensure that the engine is running while setting
up the display features.

When the occupant’s lower back
presses against the seatback
during a rear-end collision, the
head restraint moves slightly for-
ward and upward to help reduce
the risk of whiplash on the seat
occupant.

WARNING
When adjusting the seat position
Take care when adjusting the seat position to ensure that other passen-
gers are not injured by the moving seat.
Do not put your hands under the seat or near the moving parts to avoid
injury.
Fingers or hands may become jammed in the seat mechanism.
Make sure to leave enough space around the feet so they do not get stuck.
Seat adjustment
Be careful that the seat does not hit passengers or luggage.
To reduce the risk of sliding under the lap belt during a collision, do not
recline the seat more than necessary.
If the seat is reclined too far, the lap belt may slide past the hips and apply
restraint forces directly to the abdomen or your neck may contact the
shoulder belt, increasing the risk of death or serious injury in the event of
an accident.
Adjustments should not be made while driving as the seat may unexpect-
edly move and cause the driver to lose control of the vehicle.
Manual seat: After adjusting the seat, make sure that the seat is locked in

SIENNA_OM_OM08035U_(U)
4-1. Before driving
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
When starting the vehicle
Always keep your foot on the brake pedal while stopped with the engine
running. This prevents the vehicle from creeping.
When driving the vehicle
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.
Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot
parts may cause a fire if there is any flammable material nearby.

Driving
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
When driving the vehicle
During normal driving, do not turn off the engine. Turning the engine off
while driving will not cause loss of steering or braking control, but the
power assist to these systems will be lost. This will make it more difficult to
steer and brake, so you should pull over and stop the vehicle as soon as it
is safe to do so.
However, in the event of an emergency, such as if it becomes impossible
to stop the vehicle in the normal way: P. 463
Use engine braking (downshift) 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. 233)
Do not adjust the position 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, heads or other parts of their body
are not outside the vehicle.
AWD models: Do not drive the vehicle off-road.
This is not an AWD vehicle designed for off-road driving. Proceed with all
due caution if it becomes unavoidable to drive off-road.
AWD models: Do not drive across a river or through other bodies of water.
This may cause electric/electronic components to short circuit, damage
the engine 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.

SIENNA_OM_OM08035U_(U)
4-1. Before driving
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
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.
After driving through a puddle, lightly 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.
When shifting the shift lever
Do not let the vehicle roll backward while the shift lever is in a driving posi-
tion, or roll forward while the shift lever is in R. Doing so may cause the
engine to stall or lead to poor brake and steering performance, resulting in
an accident or damage to the vehicle.
Do not shift the shift lever 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 lever 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 lever to a driving position while the vehicle is moving
backward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
Moving the shift lever to N while the vehicle is moving will disengage the
engine from the transmission. Engine braking is not available when N is
selected.
Be careful not to shift the shift lever with the accelerator pedal depressed.
Shifting the shift lever to a gear 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. Doing so can damage the transmission and may
result in a loss of vehicle control.

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
indicators)
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 race the engine.
If the vehicle is in any gear 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 the engine is running, 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.
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.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
When the vehicle is parked
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
containers such as air fresheners on the instrument panel or dashboard.
Adhesive 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 lever to P, stop the engine
and lock the vehicle.
Do not leave the vehicle unattended while the engine is running.
If the vehicle is parked with the shift lever 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 engine is running or immediately
after turning the engine off.
Doing so may cause burns.
When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift
lever or depress the accelerator pedal, this could cause an accident or fire
due to engine 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.

Driving
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
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 brake booster device does not operate, do not follow other vehicles
closely and avoid hills 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.
Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted
brakes.
The brake system consists of 2 individual hydraulic systems: If one of the
systems fails, the other 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.
If the vehicle becomes stuck (AWD models)
Do not spin the wheels excessively when any of the tires is up in the air, or
the vehicle is stuck in sand or mud, etc. This may damage the driveline
components or unexpectedly propel the vehicle forward or backward, caus-
ing an accident.

NOTICE
When driving the vehicle
Do not depress the accelerator and brake pedals at the same time during
driving, as this may restrain the engine 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 lever 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.
It may be difficult to control your vehicle.
The vehicle will make abnormal sounds or vibrations.

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,
transaxle, transfer (AWD models), rear differential (AWD models), etc.
Lubricant condition for the bearings and suspension joints (where possi-
ble) and the function of all joints, bearings, etc.

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 (5150) =
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. 516)
Take notice of the following information about storage
precautions, cargo capacity and load:

Cargo capacity
Total load capacity (vehicle
capacity weight) (P. 516)
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
*
2
lb. (kg) - A*
1
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.

WARNING
Things that must not be carried in the luggage compartment
The following things may cause a fire if loaded in the luggage compart-
ment:
Receptacles containing gasoline
Aerosol cans
Storage precautions
Observe the following precautions.
Failure to do so may prevent the pedals from being depressed properly,
may block the driver’s vision, or may result in items hitting the driver or
passengers, possibly causing an accident.
Stow cargo and luggage in the luggage compartment whenever possi-
ble.
Do not stack cargo and luggage in the luggage compartment higher
than the seatbacks.
Do not place cargo or luggage in or on the following locations.
Driver’s feet
Front passenger or rear seats (when stacking items)
Instrument panel
Dashboard
Auxiliary box or tray that has no lid
Secure all items in the occupant compartment.
When you fold down the rear seats, long items should not be placed
directly behind the front seats.
Never allow anyone to ride in the luggage compartment. It is not
designed for passengers. They should ride in their seats with their seat
belts properly fastened. Otherwise, they are much more likely to suffer
death or serious bodily injury, in the event of sudden braking, sudden
swerving or an accident.
Capacity and distribution
Do not exceed the maximum axle weight rating or the total vehicle
weight rating.
Even if the total load of occupant’s weight and the cargo load is less
than the total load capacity, do not apply the load unevenly.
Improper loading may cause deterioration of steering or braking con-
trol which may cause death or serious injury.

WARNING
Cross rail adjustment
Make sure the cross rails are locked securely by pushing forward and
rearward on them.
Failure to do so may cause an unexpected accident.
When loading cargo
To use the roof rails as a roof luggage carrier, you must fit the roof rails
with two or more genuine Toyota cross rails or their equivalent.
When you load cargo on the roof luggage carrier, observe the following:
Place the cargo so that its weight is distributed evenly between the
front and rear axles.
If loading long or wide cargo, never exceed the vehicle overall length
or width. (P. 516)
Before driving, make sure the cargo is securely fastened on the roof
luggage carrier.
Loading cargo on the roof luggage carrier will make the center of grav-
ity of the vehicle higher. Avoid high speeds, sudden starts, sharp turns,
sudden braking or abrupt maneuvers, otherwise it may result in loss of
control or vehicle rollover due to failure to operate this vehicle correctly
and result in death or serious injury.
If driving for a long distance, on rough roads, or at high speeds, stop
the vehicle now and then during the trip to make sure the cargo
remains in its place.
Do not exceed 150 lb. (68 kg) cargo weight on the roof luggage carrier.

(including the cargo in the
trailer).
Your vehicle is designed primarily as a passenger-and-load-car-
rying vehicle. Towing a trailer can have an adverse impact on
handling, performance, braking, durability, and fuel
consumption. For your safety and the safety of others, you must
not overload your vehicle or trailer. You must also ensure that
you are using appropriate towing equipment, that the towing
equipment has been installed correctly and used properly, and
that you employ the requisite driving habits.
Vehicle-trailer stability and braking performance are affected by
trailer stability, brake performance and setting, trailer brakes,
the hitch and hitch systems (if equipped).
To tow a trailer safely, use extreme care and drive the vehicle in
accordance with your trailer’s characteristics and operating
conditions.

care to comply with your state’s laws when installing trailer lights.
Your vehicle will handle differently when towing a trailer. Help to avoid
an accident, death or serious injury, keep the following in mind when
towing:
Speed limits for towing a trailer vary by state or province. Do not
exceed the posted towing speed limit.
Toyota recommends that the vehicle-trailer speed limit is 65 mph
(104 km/h) on a flat, straight, dry road. Do not exceed this limit, the
posted towing speed limit or the speed limit for your trailer as set
forth in your trailer owner’s manual, whichever is lowest. Instability
of the towing vehicle-trailer combination (trailer sway) increases as
speed increases. Exceeding speed limits may cause loss of control.
Before starting out, check the trailer lights, tires and the vehicle-
trailer connections. Recheck after driving a short distance.
Practice turning, stopping and reversing with the trailer attached in
an area away from traffic until you become accustomed to the feel
of the vehicle-trailer combination.

4-1. Before driving
Reversing with a trailer attached is difficult and requires practice.
Grip the bottom of the steering wheel and move your hand to the
left to move the trailer to the left. Move your hand to the right to
move the trailer to the right. (This is generally opposite to reversing
without a trailer attached.) Avoid sharp or prolonged turning. Have
someone guide you when reversing to reduce the risk of an acci-
dent.
As stopping distance is increased when towing a trailer, vehicle-to-
vehicle distance should be increased. For each 10 mph (16 km/h)
of speed, allow at least one vehicle and trailer length.
Avoid sudden braking as you may skid, resulting in the trailer jack-
knifing and a loss of vehicle control. This is especially true on wet or
slippery surfaces.
Avoid jerky starts or sudden acceleration.
Avoid jerky steering and sharp turns, and slow down before making
a turn.
Note that when making a turn, the trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by making
a wider than normal turning radius.
Slow down before making a turn, in crosswinds, on wet or slippery
surfaces, etc.
Increasing vehicle speed can destabilize the trailer.
Take care when passing other vehicles. Passing requires consider-
able distance. After passing a vehicle, do not forget the length of
your trailer, and be sure you have plenty of room before changing
lanes.
To maintain engine braking efficiency and charging system perfor-
mance when using engine braking, do not put the transmission in
D. If in the S mode, transmission shift range position must be in 6 or
lower.
Instability happens more frequently when descending steep or long
downhill grades. Before descending, slow down and downshift. Do
not make sudden downshifts while descending steep or long down-
hill grades.
Avoid holding the brake pedal down too long or applying the brakes
too frequently. This could cause the brakes to overheat and result in
reduced braking efficiency.

Driving
Due to the added load of the trailer, your vehicle’s engine may over-
heat on hot days (at temperatures over 85°F [30°C]) when driving
up a long or steep grade. If the Engine coolant temperature gauge
overheating, immediately turn off the air conditioning (if in use), pull
your vehicle off the road and stop in a safe spot. (P. 509)
Always place wheel blocks under both the vehicle’s and the trailer’s
wheels when parking. Apply the parking brake firmly, and put the
transmission in P. Avoid parking on a slope, but if unavoidable, do
so only after performing the following:
Apply the brakes and keep them applied.
Have someone place wheel blocks under both the vehicle’s and
trailer’s wheels.
When the wheel blocks are in place, release the brakes slowly
until the blocks absorb the load.
Apply the parking brake firmly.
Shift into P and turn off the engine.
When restarting after parking on a slope:
With the transmission in P, start the engine. Be sure to keep the
brake pedal pressed.
Shift into a forward gear. If reversing, shift into R.
Release the parking brake and brake pedal, and slowly pull or
back away from the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks.

Check that the following conditions are met:
Ensure that your vehicle’s tires are properly inflated. (P. 522)
Trailer tires are inflated according to the trailer manufacturer’s recommen-
dation.
All trailer lights work as required by law.
All lights work each time you connect them.
The trailer ball is set at the proper height for the coupler on the trailer.
The trailer is level when it is hitched.
Do not drive if the trailer is not level, and check for improper tongue weight,
overloading, worn suspension, or other possible causes.
The trailer cargo is securely loaded.
The rear view mirrors conform to all applicable federal, state/provincial or
local regulations. If they do not, install rear view mirrors appropriate for tow-
ing purposes.
Break-in schedule
If your vehicle is new or equipped with any new power train components
(such as an engine, transmission, differential or wheel bearing), Toyota rec-
ommends that you do not tow a trailer until the vehicle has been driven for
over 500 miles (800 km).
After the vehicle has been driven for over 500 miles (800 km), you can start
towing. However, for the next 500 miles (800 km), drive the vehicle at a speed
of less than 50 mph (80 km/h) when towing a trailer, and avoid full throttle
acceleration.

Maintenance
If you tow a trailer, your vehicle will require more frequent maintenance due
to the additional load. (See “Scheduled Maintenance Guide” or “Owner’s
Manual Supplement”.)
Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.
If trailer sway occurs
One or more factors (crosswinds, passing vehicles, rough roads, etc.) can
adversely affect handling of your vehicle and trailer, causing instability.
If trailer swaying occurs:
Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering wheel.
Begin releasing the accelerator pedal immediately but very gradually to
reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle
and trailer should stabilize.
After the trailer swaying has stopped:
Stop in a safe place. Get all occupants out of the vehicle.
Check the tires of the vehicle and the trailer.
Check the load in the trailer.
Make sure the load has not shifted.
Make sure the tongue weight is appropriate, if possible.
Check the load in the vehicle.
Make sure the vehicle is not overloaded after occupants get in.
If you cannot find any problems, the speed at which trailer swaying occurred
is beyond the limit of your particular vehicle-trailer combination.
Drive at a lower speed to prevent instability. Remember that swaying of the
towing vehicle-trailer increases as speed increases.

WARNING
Trailer towing precautions
To tow a trailer safely, use extreme care and drive the vehicle in accordance
with the trailer’s characteristics and operating conditions. Failure to do so
could cause an accident resulting in death or serious injury. Vehicle stability
and braking performance are affected by trailer stability, brake setting and
performance, and the hitch. Your vehicle will handle differently when towing
a trailer.
To avoid accident or injury
Do not exceed the TWR, unbraked TWR, GCWR, GVWR or GAWR.
If the gross trailer weight is over 2000 lb. (907 kg), a sway control device
with sufficient capacity is required.
Adjust the tongue weight within the appropriate range. Place heavier loads
as close to the trailer axle as possible.
Do not exceed 65 mph (104 km/h), the posted towing speed limit or the
speed limit for your trailer as set forth in your trailer owner’s manual,
whichever is lowest. Slow down sufficiently before making a turn, in cross-
winds, on wet or slippery surface, etc. to help avoid an accident. If you
experience a vehicle-trailer instability from reducing a certain speed, slow
down and make sure you keep your vehicle speed under the speed of
which you experience the instability.
Do not make jerky, abrupt or sharp turns.
Do not apply the brakes suddenly as you may skid, resulting in jackknifing
and loss of vehicle control. This is especially true on wet or slippery sur-
faces.
Do not exceed the trailer hitch assembly weight, gross vehicle weight,
gross axle weight and trailer tongue weight capacities.

WARNING
To avoid accident or injury
Do not use cruise control when towing.
Slow down and downshift before descending steep or long downhill
grades. Do not make sudden downshifts while descending steep or long
downhill grades.
Vehicle-trailer instability is more likely on steep long downhills. Before
descending steep or long downhill grades, slow down and downshift. Do
not make sudden downshifts when descending steep or long downhill
grades. Avoid holding the brake pedal down too long or applying the
brakes too frequently. This could cause the brakes to overheat and result
in reduced braking efficiency.
Vehicles with compact spare tire: Do not tow a trailer when the compact
spare tire is installed on your vehicle.
Hitch
Trailer hitch assemblies have different weight capacities established by the
hitch manufacturer. Even though the vehicle may be physically capable of
towing a higher weight, the operator must determine the maximum weight
rating of the particular hitch assembly and never exceed the maximum
weight rating specified for the trailer-hitch. Exceeding the maximum weight
rating set by the trailer-hitch manufacturer can cause an accident resulting
in death or serious personal injuries.
When towing a trailer
Toyota recommends trailers with brakes that conform to any applicable fed-
eral and state/provincial regulations.
If the gross trailer weight exceeds unbraked TWR, trailer brakes are
required. Toyota recommends trailers with brakes that conform to all appli-
cable federal and state/provincial regulations.
Never tap into your vehicle’s hydraulic system, as this will lower the
vehicle’s braking effectiveness.
Never tow a trailer without using a safety chain securely attached to both
the trailer and the vehicle. If damage occurs to the coupling unit or hitch
ball, there is danger of the trailer wandering into another lane.
NOTICE
When installing a trailer hitch
Use only the position recommended by your Toyota dealer. Do not install
the trailer hitch on the bumper; this may cause body damage.
Do not directly splice trailer lights
Do not directly splice trailer lights. Directly splicing trailer lights may damage

WARNING
When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
Caution while driving
If the vehicle begins to slide due to engine failure or other circumstances, do
not lock or open the doors until the vehicle reaches a safe and complete
stop. Activation of the steering lock in this circumstance may lead to an
accident, resulting in death or serious injury.
Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving the vehicle,
press and hold the engine switch for more than 2 seconds, or press it briefly
3 times or more in succession. (P. 463)
However, do not touch the engine switch while driving except in an emer-
gency. Turning the engine off while driving will not cause loss of steering or
braking control, but the power assist to these systems will be lost. This will
make it more difficult to steer and brake, so you should pull over and stop
the vehicle as soon as it is safe to do so.
NOTICE
To prevent battery discharge
Do not leave the engine switch in ACCESSORY or IGNITION ON mode
for long periods of time without the engine running.
If the indicator on the engine switch is illuminated, the engine switch is not
off. When exiting the vehicle, always check that the engine switch is off.
Do not stop the engine when the shift lever is in a position other than P. If
the engine is stopped in another shift lever position, the engine switch will
not be turned off but instead be turned to ACCESSORY mode. If the
vehicle is left in ACCESSORY mode, battery discharge may occur.
When starting the engine
Do not race a cold engine.
If the engine becomes difficult to start or stalls frequently, have the engine
checked immediately.
Symptoms indicating a malfunction with the engine switch
If the engine switch seems to be operating somewhat differently than usual,
such as the switch sticking slightly, there may be a malfunction.

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.

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.
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.
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. 269)

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
system. Failure to do so may lead to an accident, resulting in death or seri-
ous 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. 272
Conditions under which the system may not operate properly: P. 274
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.

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.

WARNING
Before using dynamic radar cruise control
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 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. 299
Conditions under which the vehicle-to-vehicle distance control mode
may not function correctly: P. 3 01
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 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 is only intended to help the driver in
determining the following distance between the drivers own vehicle and a
designated vehicle traveling ahead. It is not a mechanism that allows care-
less 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 determines whether the following dis-
tance 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 necessary 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 does not include functions which will pre-
vent 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
Do not use dynamic radar cruise control 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
When your vehicle is towing a trailer or during emergency towing
When an approach warning buzzer is heard often
background

SIENNA_OM_OM08035U_(U)
4-5. Using the driving support systems
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 down-
hill 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.
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
Handling the radar sensor
One Blind Spot Monitor sensor is installed inside the left and right side of
the vehicle rear bumper respectively. Observe the following to ensure the
Blind Spot Monitor can function correctly.
Do not subject the sensor or surrounding area on the bumper to a strong
impact. If the sensor moves even slightly off position, the system may mal-
function and vehicles that enter the detection area may not be detected. If
the sensor or surrounding area is subject to a strong impact, always have
the area inspected by your Toyota dealer.
Do not disassemble the sensor.
Do not attach accessories or stickers to the sensor or surrounding area on
the bumper.
Do not modify the sensor or surrounding area on the bumper.
Do not paint the rear bumper any color other than an official Toyota color.
Keep the sensor and its surrounding area
on the bumper clean at all times.
If a sensor or its surrounding area on the
rear bumper is dirty or covered with snow,
the Blind Spot Monitor may not operate
and a warning message (P. 303) will be
displayed. In this situation, clear off the
dirt or snow and drive the vehicle with the
operation conditions of the BSM function
(P. 307) satisfied for approximately 10
minutes. If the warning message does not
disappear, have the vehicle inspected by
your Toyota dealer.

The BSM function uses radar sensors to detect vehicles that are trav-
eling in an adjacent lane in the area that is not reflected in the outside
rear view mirror (the blind spot), and advises the driver of the vehicles
existence via the outside rear view mirror indicator.
The areas that vehicles can be detected in are outlined below.
The range of the detection area
extends to:
Approximately 11.5 ft. (3.5 m)
from the side of the vehicle
The first 1.6 ft. (0.5 m) from the

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 BSM function is a supplementary function which alerts the driver that a
vehicle is present in the blind spot. Do not overly rely on the BSM function.
The function cannot judge if it is safe to change lanes, therefore over reli-
ance 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.

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 at
slow speeds, there is a possibility that the obstacle will come within the sen-
sor’s detection.
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/visual system
or air flow noise of the air conditioning system.

Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect an obstacle. Particular instances where
this may occur are listed below.
There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve
this problem.)
The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen may show an
abnormal display, or obstacles may not be detected.
The sensor is covered in any way.
The vehicle is leaning considerably to one side.
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.
There is another vehicle equipped with parking assist sensors in the vicin-
ity.
The sensor is coated with a sheet of spray or heavy rain.
The sensor is drenched with water on a flooded road.
The vehicle is equipped with a fender pole or wireless antenna.
Towing eyelets are installed.
The bumper or sensor receives a strong impact.
The vehicle is approaching a tall or curved curb.
The detection range is reduced due to an object such as a sign.
In harsh sunlight or intense cold weather.
The area directly under the bumpers is not detected.
If obstacles draw too close to the sensor.
A non-genuine Toyota suspension (lowered suspension, etc.) is installed.
A backlit license plate is installed.
In addition to the examples above, there are instances in which, because of
their shape, signs and other objects may be judged by a sensor to be closer
than they are.

4-6. 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 move the shift lever to P 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 block the wheels.
Failure to do so may be dangerous because it may cause the vehi-
cle to move unexpectedly, possibly leading to an accident.
If the vehicle is parked without setting the parking brake, confirm
that the shift lever cannot be moved out of P
*.
*: The shift lever will be locked if it is attempted to be shifted from P to any
other position without depressing the brake pedal. If the shift lever can be
shifted from P, there may be a problem with the shift lock system. Have the
vehicle inspected by your Toyota dealer immediately.
Use the tire chains of correct size and type.
Use SAE Class “S” type radial tire chains, with the exception of radial
cable chains or V-bar type chains.
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.

Driving
WARNING
Driving with snow tires
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.
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.
Failing 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.
NOTICE
Repairing or replacing snow tires
Request repairs or replacement of snow tires from Toyota dealers or legiti-
mate tire retailers.
This is because the removal and attachment of snow tires affects the opera-
tion of the tire pressure warning valves and transmitters.
Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.

When the outside temperature exceeds 75°F (24°C) and the air condition-
ing system is on
In order to reduce the air conditioning power consumption, the air condition-
ing system may switch to recirculated air mode automatically.
This may also reduce fuel consumption.
Recirculated air mode is selected as a default mode when the engine switch
is turned to the “ON” position (vehicles without a smart key system) or
IGNITION ON mode (vehicles with a smart key system).
It is possible to switch to outside air mode at any time by pressing .

When driving on dusty roads such as tunnels or in heavy traffic, set
to the recirculated air mode. This is effective in preventing outside air from
entering the vehicle interior. During cooling operation, setting the recircu-
lated air mode will also cool the vehicle interior effectively.

Automatic Collision Notification
In case of either airbag deployment or severe rear-end collision, the
system is designed to automatically call the response center. The
responding agent receives the vehicle’s location and attempts to
speak with the vehicle occupants to assess the level of emergency.
If the occupants are unable to communicate, the agent automati-
cally treats the call as an emergency, contacts the nearest emer-
gency services provider to describe the situation, and requests that
assistance be sent to the location.
Stolen Vehicle Location
If your vehicle is stolen, Safety Connect can work with local author-
ities to assist them in locating and recovering the vehicle. After filing
a police report, call the Safety Connect response center at 1-855-
405-6500 in the United States, 1-877-855-8377 in Puerto Rico or 1-
888-869-6828 in Canada, and follow the prompts for Safety Con-
nect to initiate this service.
In addition to assisting law enforcement with recovery of a stolen
vehicle, Safety-Connect-equipped vehicle location data may, under
certain circumstances, be shared with third parties to locate your
vehicle. Further information is available at Toyota.com in the United
States, Toyotapr.com in Puerto Rico and Toyota.ca in Canada.

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.

6-1. Maintenance and care
Cleaning and protecting the vehicle exterior
Working from top to bottom, liberally apply water to the vehicle
body, wheel wells and underside of the vehicle to remove any dirt
and dust.
Wash the vehicle body using a sponge or soft cloth, such as a
chamois.
For hard-to-remove marks, use car wash soap and rinse thoroughly
with water.
Wipe away any water.
Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle
body is cool.
Automatic car washes
Before washing the vehicle:
Fold the mirrors.
Turn off the power back door system. (if equipped)
Turn off the power sliding door system. (if equipped)
Start washing from the front of the vehicle. Make sure to extend the mirrors
before driving.
Brushes used in automatic car washes may scratch the vehicle surface and
harm your vehicle’s paint.
High pressure car washes
Do not allow the nozzles of the car wash to come within close proximity of
the windows.
Before using the car wash, check that the fuel filler door on your vehicle is
closed properly.
When using a car wash (vehicles with a smart key system)
If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. Place the key in a posi-

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. (P. 474)
Vehicles with compact spare tire: The compact spare tire is not
equipped with the tire pressure warning valve and transmitters.
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. 422)
Initializing the tire pressure warning system
When the tire size is changed, the tire pressure warning system
must be initialized.
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.
How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn the engine switch off.
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. (P. 522)
Make sure to adjust the tire pressure to the specified cold tire infla-
tion pressure level. The tire pressure warning system will operate
based on this pressure level.
Turn the engine switch to the “ON” position (vehicles without a
smart key system) or IGNITION ON mode (vehicles with a smart
key system).

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 number given by dividing the maximum load by 1.10 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. 529)

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 restriction. Snow tires
should be installed on all wheels. (P. 327)
If the tread on snow tires wears down below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is lost.

higher.
The tire pressure warning system may be disabled in the following condi-
tions:
(When the condition becomes normal, the system will work properly.)
If electronic devices or facilities using similar radio wave frequencies are
nearby.
If a radio set at similar frequencies is in use in the vehicle.
If a window tint that affects the radio wave signals is installed.
If there is a lot of snow or ice on the vehicle, in particular around the
wheels or wheel housings.
If non-genuine Toyota wheels are used. (Even if you use Toyota wheels,
the tire pressure warning system may not work properly with some types
of tires.)
If tire chains are used.
Initializing the tire pressure warning system
Initialize the system with the tire inflation pressure adjusted to the speci-
fied level.
If you press the tire pressure warning reset switch accidentally
If initialization is performed, adjust the tire inflation pressure to the speci-
fied level and initialize the tire pressure warning system again.
When the initialization of the tire pressure warning system has failed
Initialization can be completed in a few minutes. However, in the following
cases, the settings have not been recorded and the system will not oper-
ate properly. If repeated attempts to record tire inflation pressure settings
are unsuccessful, have the vehicle inspected by your Toyota dealer.

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. Make sure to replace the tire pressure warning valve and
transmitter when replacing the tire. (P. 421)
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.

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.
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 advanced 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. 421)
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
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.
NOTICE
Replacing tire pressure warning valves and transmitters
Because tire repair or replacement may affect the tire pressure warn-
ing valves and transmitters, make sure to have tires serviced by your
Toyota dealer or other qualified service shop. In addition, make sure to
purchase your tire pressure warning valves and transmitters at your
Toyota dealer.
Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly
with non-genuine wheels.
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.

WARNING
Replacing light bulbs
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 headlight unit. This
may damage the headlights or cause condensation to build up on the lens.
Do not attempt to repair or disassemble the bulb, socket, electrical wiring,
or sub components. This may cause serious injury due to electric shock.
Vehicles with discharge headlights:
While the low beam headlights are
turned on, and for a short time after they
have been turned off, metal compo-
nents at the rear of the headlight
assembly will be extremely hot. To pre-
vent burns, do not touch these metal
components until you are certain they
have cooled down.

WARNING
If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact your Toyota
dealer. The vehicle will become extremely unstable during braking, and the
ABS system may fail, which could cause an accident resulting in death or
serious injury.
When the electric power steering system warning light comes on
The steering wheel may 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.
Vehicles with standard tires:
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, change it with the spare tire and have the flat tire
repaired by the nearest Toyota dealer.
Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate,
you could lose control of the steering wheel or the brakes.
Vehicles with run-flat tires:
Decelerate to the lowest appropriate speed as soon as possible. Do
not drive over 50 mph (80 km/h).
Check and 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. Have the tire
replaced by the nearest Toyota dealer.
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.

When trouble arises
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.

WARNING
Replacing a flat tire
Observe the following precautions.
Failure to do so may result in serious injury:
Do not touch the disc wheels or the area around the brakes immedi-
ately after the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area
around the brakes will be extremely hot. Touching these areas with
hands, feet or other body parts while changing a tire, etc. may result
in burns.
Remove the spare tire before jacking up the vehicle. If the spare tire
is removed after jacking up the vehicle, the tire carrier and the spare
tire may interfere with the jack and cause a serious accident.
Failure to follow these precautions could cause the wheel nuts to
loosen and the tire to fall off, resulting in death or serious injury.
Have the wheel nuts tightened with a torque wrench to 76 ft•lbf
(103 N•m, 10.5 kgf•m) as soon as possible after changing wheels.
When installing a tire, only use wheel nuts that have been specifi-
cally designed for that wheel.
If there are any cracks or deformations in the bolt screws, nut
threads or bolt holes of the wheel, have the vehicle inspected by
your Toyota dealer.
When installing the wheel nuts, be sure to install them with the
tapered end facing inward. (P. 433)
For vehicles with power sliding door and/or power back door: In cases
such as when replacing tires, make sure to turn off the power sliding
door main switch (P. 124) and/or the power back door main switch
(P. 136). Failure to do so may cause the sliding door and/or the back
door to operate unintentionally if the power sliding door switch and/or
the power back door switch is accidentally touched, resulting in hands
and fingers being caught and injured.

Water can be used in an emer-
gency if coolant is unavailable.
Start the engine and turn the air conditioning system on to check
that the radiator cooling fans operate and to check for coolant leaks
from the radiator or hoses.
The fans operate when the air conditioning system is turned on immedi-
ately after a cold start. Confirm that the fans are operating by checking the
fan sound and air flow. If it is difficult to check these, turn the air condition-
ing system on and off repeatedly. (The fans may not operate in freezing
temperatures.)
If the fans are not operating:
Stop the engine immediately and contact your Toyota dealer.
If the fans are operating:
Have the vehicle inspected at the nearest Toyota dealer.

When trouble arises
WARNING
When inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot.
Keep hands and clothing (especially a tie, a scarf or a muffler) away from
the fan and belts. Failure to do so may cause the hands or clothing to be
caught.
Do not loosen the radiator cap or the coolant reservoir cap while the
engine and radiator are hot. High temperature steam or coolant could
spray out.
NOTICE
When adding engine coolant
Add coolant slowly after the engine has cooled down sufficiently. Adding
cool coolant to a hot engine too quickly can cause damage to the engine.
To prevent damage to the cooling system
Observe the following precautions:
Avoid contaminating the coolant with foreign matter (such as sand or dust
etc.).
Do not use any coolant additive.

When trouble arises
WARNING
When attempting to free a stuck vehicle
If you choose to push the vehicle back and forth to free it, make sure the
surrounding area is clear to avoid striking other vehicles, objects or people.
The vehicle may also lunge forward or lunge back suddenly as it becomes
free. Use extreme caution.
When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may
cause an accident resulting in death or serious injury.
NOTICE
To avoid damaging the transaxle and other components
Avoid spinning the wheels and pressing the accelerator pedal more than
necessary.
If the vehicle remains stuck even after these procedures are performed,
the vehicle may require towing to be freed.

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: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice
for good fuel economy and
good starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced
with SAE 0W-20 at the next oil
change.
Oil viscosity (0W-20 is explained here as an example):
The 0W in 0W-20 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 20 in 0W-20 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.
How to read oil container label:
The International Lubricant
Specification Advisory Commit-
tee (ILSAC) Certification Mark
is added to some oil containers
to help you select the oil you
should use.

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 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, EPAs lowest additives concentra-
tion 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 in your vehicle.
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 panel 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 gaso-
line 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 catalytic converters
causing the emission control system to malfunction.
Do not use gasohol other than that stated here.
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.

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.
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
Standard 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.

When the speed-detecting automatic door lock and shift-linked automatic
door lock are both on, the door lock operates as follows:
When shifting the shift position to any position other than P, all the doors
will be locked.
If the vehicle is started with all the doors locked, the Speed linked door
locking function would not operate.
If the vehicle is started with any door unlocked, the Speed linked door
locking function will operate.
When the smart key system is off, the entry unlock function cannot be cus-
tomized.
When the doors remain closed after unlocking the doors and the timer acti-
vated automatic door lock function activates, signals will be generated in
accordance with the operation buzzer volume and operational signal
(Emergency flashers) function settings.
When customizing on the audio/visual system screen
Stop the vehicle in a safe place, apply the parking brake, and shift the shift
lever to P. Also, to prevent battery discharge, leave the engine running while
customizing the features.
WARNING
During customization
As the engine needs to be running 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.

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.
Même si les véhicules sont conçus différemment, la plupart des
conducteurs peuvent maintenir une distance de 10 in. (250 mm), même
si leur siège se trouve complètement vers l’avant, simplement en incli-
nant un peu le dossier du siège vers l’arrière. Si la visibilité avant est
moindre après avoir incliné le dossier 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.

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
sécuritaires 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
à la portière sur le siège du passager ni
sortir la tête ou les mains à l’extérieur
du véhicule.

AVERTISSEMENT
Précautions relatives aux coussins gonflables SRS
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
du conducteur se déploient.
Ne fixez rien sur des zones telles que
les portières, le pare-brise, les glaces
de portières, les montants avant ou
arrière, le brancard de pavillon et la poi-
gnée de maintien.
Véhicules non dotés du système Smart
key : N’accrochez pas d’objets lourds,
pointus ou durs, par exemple des clés
ou des accessoires, à la clé. Ces objets
pourraient empêcher le déploiement du
coussin gonflable SRS de protection
des genoux ou être projetés violem-
ment dans l’assise du siège du conduc-
teur par la force du déploiement, et
donc présenter un danger.

AVERTISSEMENT
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 composants de 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.
Si vous avez de la difficulté à respirer après le déploiement des coussins
gonflables SRS, ouvrez une portière ou une glace pour laisser entrer l’air,
ou quittez le véhicule si vous pouvez le faire en toute sécurité. Dès que
possible, nettoyez tous les résidus afin d’éviter les irritations 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.
