The installation of a mobile two-way radio system in your vehicle could affect
electronic systems such as:
● Fuel cell system
● Anti-lock brake system
● SRS airbag system
● Seat belt pretensioner system
● Toyota Safety Sense 2.0
Be sure to check with your Toyota dealer for precautionary measures or spe-
cial instructions regarding installation of a mobile two-way radio system.
High voltage parts and cables on the fuel cell vehicles emit approximately the
same amount of electromagnetic waves as the conventional gasoline pow-
ered vehicles or home electronic appliances despite of their electromagnetic
shielding.
Unwanted noise may occur in the reception of the mobile two-way radio.

The vehicle is equipped with sophisticated computers that will record certain
data, such as:
The recorded data varies according to the vehicle grade level and options
with which it is equipped. These computers do not record conversations or
sounds, and only record images outside of the vehicle in certain situations.
• Engine speed /Electric motor speed (traction motor speed)
• Accelerator status
• Brake status
• Vehicle speed
• Operation status of the driving assist systems, such as the ABS and pre-
collision system
• Images from the 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.

WARNING
■ General precautions while driving
Driving under the influence: Never drive your vehicle when under the influ-
ence of alcohol or drugs that have impaired your ability to operate your vehi-
cle. Alcohol and certain drugs delay reaction time, impair judgment and
reduce coordination, which could lead to an accident that could result in
death or serious injury.
Defensive driving: Always drive defensively. Anticipate mistakes that other
drivers or pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full attention to driving. Anything that
distracts the driver, such as adjusting controls, talking on a cellular phone or
reading can result in a collision with resulting death or serious injury to you,
your occupants or others.
■ General precaution regarding children’s safety
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral.
There is also a danger that children may injure themselves by playing with
the windows, 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 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.
■ 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 6)
● 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.
Failure to do so may cause death or serious injury.
■ Wearing a seat belt
● Ensure that all passengers wear a seat belt.
● Always wear a seat belt properly.
● Each seat belt should be used by one person only. Do not use a seat belt
for more than one person at once, including children.
● Toyota recommends that children be seated in the rear seat and always
use a seat belt and/or an appropriate child restraint system.
● To achieve a proper seating position, do not recline the seat more than
necessary. The seat belt is most effective when the occupants are sitting
up straight and well back in the seats.
● Do not wear the shoulder belt under your arm.
● Always wear your seat belt low and snug across your hips.
■ 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 the 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
● 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 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 1)
■ 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.
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.

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 sev-
eral 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
still maintaining control of the foot pedals, steering wheel, and your view
of the instrument panel controls.

MIRAI_OM_USA_OM62054U(18MY)_O
M62048U(19MY)
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 sys-
tem. Toyota strongly recommends that all infants and children be placed in
the rear seats of the vehicle and properly restrained. The rear seats are
safer for infants and children than the front passenger seat. (P. 56)
● If the seat belt extender has been con-
nected to the front seat belt buckles but
the seat belt extender has not also been
fastened to the latch plate of the seat
belt, the SRS front airbags will judge
that the driver and front passenger are
wearing the seat belt even though the
seat belt has not been connected. In
this case, the SRS front airbags may
not activate correctly in a collision,
resulting in death or serious injury in the
event of a collision. Be sure to wear the
seat belt with the seat belt extender.

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

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 SRS seat cushion airbag from activating correctly, disable the
system or cause the side airbags and SRS seat cushion airbag to inflate
accidentally, resulting in death or serious injury.
● Do not attach anything to or lean any-
thing against areas such as the dash-
board, steering wheel pad and lower
portion of the instrument panel.
These items can become projectiles
when the SRS driver, front passenger
and knee airbags deploy.
● Do not attach anything to areas such as
a door, windshield, side windows, front
or rear pillar, roof side rail and assist
grip.

WARNING
■ SRS airbag precautions
● 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 pillars garnishes, are damaged or cracked, have
them replaced by your Toyota dealer.
● Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents the sensor
from detecting the passenger’s weight properly. As a result, the SRS front
airbags for the front passenger may not deploy in the event of a collision.
■ Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications
without consulting your Toyota dealer. The SRS airbags may malfunction or
deploy (inflate) accidentally, causing death or serious injury.
● Installation, removal, disassembly and repair of the SRS airbags
● Repairs, modifications, removal or replacement of the steering wheel,
instrument panel, dashboard, seats or seat upholstery, front, side and rear
pillars or roof side rails
● Repairs or modifications of the front fender, front bumper, or side of the
occupant compartment
● Installation of a grille guard (bull bars, kangaroo bar, etc.), snow plows,
winches, or roof luggage carrier
● Modifications to the vehicle’s suspension system
● Installation of electronic devices such as mobile two-way radios and CD
players
● Modifications to your vehicle for a person with a physical disability

■ If the SRS airbags deploy (inflate)
● Slight abrasions, burns, bruising, etc., may be sustained from SRS airbags,
due to the extremely high speed deployment (inflation) by hot gases.
● A loud noise and white powder will be emitted.
● Parts of the airbag module (steering wheel hub, airbag cover and inflator) as
well as the front seats, parts of the front and rear pillars, and roof side rails,
may be hot for several minutes. The airbag itself may also be hot.
● The windshield may crack.
● 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. 72 )
■ 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.
● The SRS seat cushion airbag on the front passenger seat will not operate if
the occupant is not wearing a seat belt.

■ SRS airbag deployment conditions (SRS side and curtain shield airbags)
● The SRS side and curtain shield airbags will deploy in the event of an
impact that exceeds the set threshold level (the level of force corresponding
to the impact force produced by an approximately 3300 lb. [1500 kg] vehicle
colliding with the vehicle cabin from a direction perpendicular to the vehicle
orientation at an approximate speed of 12 - 18 mph [20 - 30 km/h]).
● 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 airbags
(SRS front airbags)
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 or low-
speed frontal collision.
● Collision from the side
● Collision from the rear
● Vehicle rollover
● Collision from the side to the vehicle
body other than the passenger compart-
ment
● Collision from the side at an angle
● Collision from the rear
● Vehicle rollover

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 passenger’s seat belt plate has not been left inserted
into the buckle before someone sits in the front passenger seat.
● Make sure the “AIR BAG OFF” indicator light is not illuminated when using
the seat belt extender for the front passenger seat. If the “AIR BAG OFF”
indicator light is illuminated, disconnect the extender tongue from the seat
belt buckle, and reconnect the seat belt. Reconnect the seat belt extender
after making sure the “AIR BAG ON” indicator light is illuminated. If you
use the seat belt extender while the “AIR BAG OFF” indicator light is illumi-
nated, the SRS airbags for the front passenger will not activate, which
could cause death or serious injury in the event of a collision.
● Do not apply a heavy load to the front passenger seat or equipment (e.g.
seatback pocket).
● Do not put weight on the front passenger seat by putting your hands or
feet on the front passenger seat seatback from the rear passenger seat.
● Do not let a rear passenger lift the front passenger seat with their feet or
press on the seatback with their legs.
● Do not put objects under the front passenger seat.

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. 59)
● 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 rear door child-protector lock or the window lock switch to
avoid children opening the door while driving or operating the
power window accidentally. (P. 135, 167)
● Do not let small children operate equipment which may catch or
pinch body parts, such as the power window, hood, trunk, seats,
etc.
Observe the following precautions when children are in the vehi-
cle.
Use a child restraint system appropriate for the child, until the
child becomes large enough to properly wear the vehicle’s seat
belt.
WARNING
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral.
There is also a danger that children may injure themselves by playing with
the windows or other features of the vehicle. In addition, heat build-up or
extremely cold temperatures inside the vehicle can be fatal to children.

WARNING
■ When a child is riding
Observe the following precautions.
Failure to do so may result in death or serious injury.
● For effective protection in automobile accidents and sudden stops, a child
must be properly restrained, using a seat belt or child restraint system
depending on the age and size of the child.
● 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.
● Holding a child in your or someone else’s arms is not a substitute for a
child restraint system. In an accident, the child can be crushed against the
windshield or between the holder and the interior of the vehicle.
● Place one child to a child restraint system and then secure the child with
the harness of the child restraint system.
■ Handling the child restraint system
If the child restraint system is not properly fixed in place, the child or other
passengers may be seriously injured or even killed in the event of sudden
braking, sudden swerving, or an accident.
● If the vehicle were to receive a strong impact from an accident, etc., it is
possible that the child restraint system has damage that is not readily visi-
ble. In such cases, do not reuse the restraint system.
● Make sure you have complied with all installation instructions provided
with the child restraint system manufacturer and that the system is prop-
erly secured.
● Keep the child restraint system properly secured on the seat even if it is
not in use. Do not store the child restraint system unsecured in the pas-
senger compartment.
● If it is necessary to detach the child restraint system, remove it from the
vehicle or store it securely in the trunk.

WARNING
■ When installing a child restraint system
Observe the following when installing child restraint system to the front pas-
senger seat if it is unavoidable. The front passenger SRS airbag inflates
with considerable speed and force that if not observed may lead to death or
serious injury to the child.
● 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.
If the head restraint interferes with the child restraint system installation
and the head restraint can be removed, remove the head restraint.
● Do not allow the child to lean his/her head or any part of his/her body
against the door or the area of the seat, front pillars or roof side rails from
which the SRS side airbags or SRS curtain shield airbags deploy even if
the child is seated in the child restraint system. It is dangerous if the SRS
side and curtain shield airbags inflate, and the impact could cause death
or serious injury to the child.
● When a booster seat is installed, always ensure that the shoulder belt is
positioned across the center of the child’s shoulder. The belt should be
kept away from the child’s neck, but not so that it could fall off the child’s
shoulder.
● A forward-facing child restraint system
may be installed on the front passenger
seat only when it is unavoidable. When
installing a forward-facing child restraint
system on the front passenger seat,
move the seat as far back as possible,
and raise the seat to the upper most
position, even if the “AIR BAG OFF”
indicator light is illuminated.

WARNING
■ When installing a child restraint system
Observe the following precautions.
Failure to do so may result in death or serious injury.
● Do not allow children to play with the seat belt. If the seat belt becomes
twisted around a child’s neck, it may lead to choking or other serious inju-
ries that could result in death.
If this occurs and the buckle cannot be unfastened, scissors should be
used to cut the belt.
● Ensure that the belt and plate are securely locked and the seat belt is not
twisted.
● Shake the child restraint system left and right, and forward and backward
to ensure that it has been securely installed.
● After securing a child restraint system, never adjust the seat.
● When a booster seat is installed, always ensure that the shoulder belt is
positioned across the center of the child’s shoulder. The belt should be
kept away from the child’s neck, but not so that it could fall off the child’s
shoulder.
● Follow all installation instructions provided by the child restraint system
manufacturer.
■ When 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. 32)
■ Do not use a seat belt extender
If a seat belt extender is used when installing a child restraint system, the
seat belt will not securely hold the child restraint system, which could cause
death or serious injury to the child or other passengers in the event of sud-
den braking, sudden swerving or an accident.

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

Fuel cell vehicle characteristics
This diagram is for illustrative purposes only and may differ from the
actual vehicle.
Fuel cell vehicles efficiently use electricity, which is generated
by a chemical reaction between hydrogen and oxygen in a fuel
cell stack, and electricity charged in a traction battery to drive
the electric motor (traction motor).
The fuel is H
2
(compressed hydrogen gas), so the exhaust is
only water and water vapor. As they do not release emissions
such as CO
2
(Carbon Dioxide) and NOx (Nitrogen Oxides), fuel
cell vehicles are environmentally friendly vehicles.

The electric motor (traction motor) allows smooth, powerful takeoff
and acceleration. This vehicle drives similarly to a gasoline vehicle
without any special actions by the driver. (P. 172) As there are no
engine sounds and the vehicle is quiet, operation noises unique to
fuel cell vehicle components may be heard. (P. 88 )
The system may behave differently on cold days. It is performing a
special cold-start process to improve start-up performance. (P. 189)
Operation noises (P. 88), purge process (P. 189), etc., differ from
usual. However, this is not a malfunction.
Compressed hydrogen gas fuel can be filled at hydrogen stations.

■ Sounds unique to the fuel cell vehicle
Due to the design of your fuel cell vehicle, there are various relays, valves
and pumps which under normal driving conditions will produce sounds. This
is a normal characteristic of the vehicle and does not indicate a malfunction.
Furthermore, way of hearing may differ based on usage environment or con-
dition.
Noticeable sounds Source of the sounds
Clunking, clicking and clack-
ing
Operation of relays and hydrogen tank
valves
Sounds may come from under the floor or
behind the rear seats.
(Sounds may be heard when starting the
fuel cell system.)
Knocking The parking lock is engaged
Sounds may come from the motor
compartment.
(Sounds may be heard when press the P
position switch or stopping the fuel cell
system.)
Whooshing, squealing Gas is flowing through the nozzle and
valves
Sounds may come from behind the rear
seats, or from the dispenser hose/nozzle.
(Sounds may be heard when filling the
fuel.)
• High pitch sound
• Gurgle sound
• Pulsing sound
Operation of the pumps
Sounds may come from the motor com-
partment or under the front seats.
(In particular, sounds may be heard when
starting the fuel cell system, accelerating
from a stop, or press the H
2
O switch. The
sound may be louder when in Br mode or
when the vehicle decelerates during
dynamic radar cruise control.)
Humming sound Operation of the pumps are speeding up
Sounds may come from the motor com-
partment or under the front seats.
(In particular, sounds may be heard when
accelerating or decelerating.)
Whooshing sound Operation of the hydrogen injector
Sounds may come from under the front
seats or behind the rear seats.
(In particular, sounds may be heard when

■ Regenerative braking
In the following situations, the vehicle generates electricity from the decelera-
tion of the vehicle while driving.
● The accelerator pedal is released while driving with the shift position in D.
● The brake pedal is depressed while driving with the shift position in D.
■ Charging the traction battery
Because electricity generated by the fuel cell stack and regenerative braking
charges the traction battery, the battery does not need to be charged from an
outside source. However, if the vehicle is left parked for a long time, the trac-
tion battery will slowly discharge. For this reason, be sure to drive the vehicle
at least once every few months for at least 30 minutes or 10 miles (16 km).
If the traction battery becomes fully discharged and you are unable to start
the fuel cell system, contact your Toyota dealer.
■ Charging the 12-volt battery
P. 454
■ Parking
Because there is no engine sound or vibration, it is easy to mistake the fuel
cell vehicle for being off when it is actually still running, as indicated by the
“READY” indicator being illuminated. For safety, make sure to always shift the
shift position to P and apply the parking brake when parked.
■ Maintenance, repair, recycling, and disposal
Contact your Toyota dealer regarding maintenance, repair, recycling, and dis-
posal. Do not dispose of the vehicle or any of its components yourself.
• Humming sound
• High pitch sound
Operation of the motor
Sounds may come from the motor com-
partment.
(In particular, sounds may be heard when
accelerating or decelerating.)
Blowing and draining sound Exhaust water or air is being purged
Sounds may come from the rear of the
vehicle.
May also occur periodically while parked
when it is cold to prevent freezing.
(Sounds may be heard when vehicle is
stopped, fuel cell system is stopped, park-
ing.)

When a certain level of impact from an accident is detected, the fuel
cell system is shut down and the system shuts out the high voltage.
Also, the fuel supply is stopped from the hydrogen tank valves. If the
emergency shut off system activates, your vehicle will not restart. To
restart the fuel cell system, contact your Toyota dealer.
A message is automatically displayed when a malfunction occurs in
the fuel cell system or an improper operation is attempted.
If a warning message is shown on
the multi-information display, read
the message and follow the
instructions. (P. 426)
Fuel cell vehicles do not have engine sounds like gasoline vehicles.
Therefore, it makes an artificial noise at low speeds to notify pedestri-
ans and nearby vehicles that it is approaching. The sound varies with
speed and will stop when the vehicle exceeds approximately 15 mph
(25 km/h).

There is an air intake vent beside
the rear left seat for the purpose
of cooling the traction battery. If
the air intake vent is blocked, it
could lead to a reduction in trac-
tion battery output.
■ If a warning light comes on, a warning message is displayed, or the
12-volt battery connection is disconnected
The fuel cell system may not be able to restart.
If the “READY” indicator does not come on, even when the start procedure is
repeated, contact your Toyota dealer.
■ If “Hydrogen Leakage Detected Visit Your Dealer” is displayed on the
multi-information display
A small amount of hydrogen gas may be leaking. Have the vehicle inspected
immediately at the nearest Toyota dealer.
■ If “FC System Shutdown due to Hydrogen Leakage Stop Your Vehicle in
a Safe Place and Contact Your Dealer” is displayed on the multi-informa-
tion display
● Hydrogen gas may be leaking.
When hydrogen gas is leaking or some other malfunction is detected:
P. 98
● The air conditioning system will shut off automatically.
■ Running out of fuel
When the vehicle has run out of fuel and the fuel cell system cannot be
started, refuel the vehicle until the low fuel level warning light (P. 420) turns
off before trying to restart. It may not be able to restart if the refueled amount
is too low (less than about 2.7 lb. [1.2 kg]).

■ Fuel cell stack
● Depending on the usage environment, the fuel cell power output may
decline over the life of the vehicle. However, this will have almost no effect
on driving performance.
● In the following situations, the fuel cell power output may decline faster than
normal driving:
• Extended use in areas with high amounts of dust
• Extended use in areas with high levels of sulfur (such as volcanoes or hot
springs).
• Extended use in areas with high concentrations of the following
substances:
-Organic solvents, such as paint and thinner
-Amine-related materials such as ammonia
-Chlorinated substances such as salt air and snow-melting agent
However, upon returning to normal environment, the fuel cell power output
will recover over time.
• Salt water gets into the air cleaner filter
It is recommended to replace the air cleaner filter and clean the surround-
ing components. Have the vehicle inspected at your Toyota dealer
• The number of times the fuel cell system is started and stopped is exces-
sively high
• Extended use in freezing temperatures
■ Hydrogen tanks
● The hydrogen tanks are the high-pressure storage containers that are filled
with compressed hydrogen gas. The vehicle can be refueled at hydrogen
stations.
● The hydrogen tanks have an expiration date. Vehicles with expired hydro-
gen tanks must not be driven or refueled until the hydrogen tanks are
replaced. The expiration date is written on the inside of the fuel door. Con-
sult your Toyota dealer.
● When disposing of the hydrogen tanks or the hydrogen tank valves, consult
your Toyota dealer for details.

■ Fuel cell stack coolant
● Fuel cell stack coolant uses a specifically-designed fluid with high electrical
insulation properties, in order to safely cool the high-voltage fuel cell stack.
● Never add water or other coolants to the fuel cell stack cooling system, as
they will cause permanent damage.
● Consult your Toyota dealer for replenishing or changing the fuel cell stack
coolant.
■ Ion filter
● An ion filter is installed in the coolant lines for the fuel cell stack, in order to
maintain the normal insulation properties of the coolant.
● It is necessary to periodically change the ion filter. (P. 428) Contact your
Toyota dealer for this periodic maintenance.
■ Tailpipe
● When the power switch is turned off and the fuel cell system is stopped
(P. 187) after driving, exhaust water is discharged. Be careful when stand-
ing behind the vehicle to avoid dripping or spraying.
● It is possible to manually purge the exhaust. This may be desirable, for
instance, before parking in a garage. This is done by pressing the H
2
O
switch. (P. 187)
● On cold days, water vapor in the exhaust may appear as a white mist emit-
ted from the tailpipe. This is not a malfunction.
● If the tailpipe is blocked, the fuel cell system will stop.
■ Hydrogen detectors
When the power switch is turned to ON mode, the hydrogen detectors are
activated.
96
2. Fuel cell vehicle
MIRAI_OM_USA_OM62054U(18MY)_O

■ Power output restriction
When the power output is restricted, the vehicle may fail to accelerate or even
decelerate, even though the accelerator pedal is depressed. If a safe driving
speed cannot be maintained, stop the vehicle in a safe place away from the
traffic. This may be caused by the following conditions:
● The coolant temperature may be too high. This can be caused by driving
conditions such as repeated sudden acceleration and deceleration, continu-
ous driving on an incline, continuous driving at high altitudes with a high
load, etc. In such situations, the power output restriction indicator (amber) is
displayed on the main display, “High FC Temperature Reduced Power” is
displayed on the multi-information display, and the power output is
restricted. Once the coolant returns to normal temperature, the power out-
put will return to normal. (P. 428)
● The remaining fuel may be low. After the low fuel warning indicator comes
on, the output power will be gradually restricted in order to extend the possi-
ble driving distance. Once getting to this point, the remaining driving dis-
tance possible is short. Immediately refill the vehicle with hydrogen.
● On cold days, the low fuel warning indicator comes on faster than usual and
the output power is restricted.
■ Vehicle proximity notification system
In the following cases, the vehicle proximity notification system may be diffi-
cult to hear for people around.
● In very noisy areas
● In wind or rain
Also, because the vehicle proximity notification system is located in the front
of the vehicle, it may be more difficult to hear from the rear of the vehicle
compared to the front.
■ Electromagnetic waves (EMF)
● High-voltage parts and cables in fuel cell vehicles have an electromagnetic
shielding configuration, and therefore emit approximately the same amount
of electromagnetic waves as conventional gasoline-powered vehicles or
home electronic appliances.
● Your vehicle may cause sound interference in some third party-produced
radio parts.
■ Traction battery
The traction battery has a limited service life. The lifespan of the traction bat-
tery can change according to driving style and driving conditions.

■ Hydrogen Gas Characteristics
● Hydrogen gas ignites more easily than gasoline. However, it is lighter than
air and disperses quickly. So even if hydrogen were to leak from the system,
it would quickly dilute until it is no longer flammable.
● As with gasoline and natural gas, hydrogen gas is not dangerous if it is han-
dled properly. Thoroughly read and understand the characteristics shown in
the table below.

■ Basic concepts of hydrogen safety
● Prevent leakage
The pipe joints of the hydrogen pipelines are designed to prevent leaks.
The joints are checked for gas leakage at every official vehicle inspection.
● Detect to stop leakage
• The vehicle is equipped with hydrogen detectors. If the hydrogen detec-
tors detect a leak, the hydrogen tank valves automatically close to pre-
vent more hydrogen from escaping.
• The vehicle is equipped with a collision sensor. If the collision sensor
detects a collision, the hydrogen tank valves automatically close to pre-
vent hydrogen gas from leaking from any damaged components.
● Disperse the leaked hydrogen gas
The hydrogen tanks and pipelines are located outside of the passenger
compartment, so any leaked gas will disperse into the atmosphere by
design.
● Eliminate sources of fire
No source of fire is located near the hydrogen pipelines by design.
WARNING
■ Hydrogen-related components
● Never alter, customize, or disassemble any hydrogen-related parts.
● The hydrogen tanks, fuel cell stack, hydrogen pipelines, and connecting
components are filled with hydrogen gas. Do not remove or disassemble
these parts. Doing so can cause a hydrogen gas leak, resulting in fire or
explosion of the vehicle, which may result in death or serious injury.
■ When hydrogen gas leak or other malfunction is detected
● If a large amount of hydrogen gas leaking is noticed, turn off the power
switch, exit the vehicle, and stay far away from it. Display warning signs
and keep sources of fire away from the vehicle. If possible, get assistance.
When the above is done, immediately contact your Toyota dealer.
● If you notice gas leaking or any other malfunction, immediately stop the
vehicle in a safe and well-ventilated place, exit the vehicle, and stay far
away from it.
● If a warning message is shown on the multi-information display, immedi-
ately stop the vehicle in a safe, well-ventilated place.

WARNING
■ Tailpipe
● Do not directly touch the water or steam coming out of the tailpipe. Doing
so may cause low-temperature burns.
● The fuel cell vehicle generates water during power generation. The gener-
ated water discharged from the tailpipe is not suitable for drinking. Never
drink the water coming out of the tailpipe.
● You may notice a strange odor from the tailpipe for a while after the pur-
chase of a new vehicle or after an extended period of non-use, but this is
not a malfunction. Also, the odor is harmless but it may be unpleasant, so
do not breathe in the exhaust.
■ High-voltage and high-temperature precautions
This vehicle is equipped with a high-voltage system. Follow the instructions
below as high-voltages can cause severe burns and electric shock that may
result in death or serious injury.
● Never touch, disassemble, remove, or replace the high-voltage parts,
cables (orange), or connectors.
● The components inside the motor compartment will become hot during
operation. Be careful of both the high-voltage and high-temperature, and
always obey the warning labels on the vehicle.
● Never touch the service plugs that are
installed on the fuel cell stack and the
traction battery. The service plugs are
used to block high-voltages from the
fuel cell stack and the traction battery
during maintenance or repair at your
Toyota dealer.

WARNING
■ Precautions in case of an accident
In the event of an accident, observe the following precautions. Failure to do
so can cause fire or electric shocks, resulting in death or serious injury.
● Stop the vehicle in a safe place to prevent subsequent accidents. Shift the
shift position to P and apply the parking brake.
● Check for hydrogen gas leakage.
Hydrogen leaks will cause a warning message to be shown on the multi-
information display. Larger leaks may also be audible.
● If a large amount of hydrogen gas leaking is noticed, turn off the power
switch, exit the vehicle, and stay far away from it. Display warning signs
and keep sources of fire away from the vehicle. If possible, get assistance.
When the above is done, immediately contact your Toyota dealer.
● Do not touch the high-voltage parts, cables (orange), or connectors.
● If electric wires are exposed inside or outside your vehicle, an electric
shock may occur. Never touch exposed electric wires.
● If a fluid leak occurs, do not touch the fluid as it may be the strong alkaline
electrolyte from the traction battery. If it comes into contact with your skin
or eyes, wash it off immediately with a large amount of water, and seek
immediate medical attention.
● In case of a vehicle fire, the hydrogen gas in the hydrogen tanks is
released via the hydrogen tank valves toward the rear of the vehicle
angled downward, in order to reduce the damage to the hydrogen tanks.
Keep away from the vehicle.
● If a vehicle fire occurs, it can be extinguished with a Class A, B, or C fire
extinguisher. If using water, apply a large amount from a hydrant.
● If your vehicle needs to be towed, do so with the front wheels lifted. If the
wheels are touching the ground, the electric motor (traction motor) may
continue to generate electricity. This may cause a fire.

WARNING
■ Traction battery
● Never resell, transfer, or modify the traction battery. To prevent accidents,
traction batteries that have been removed from disposed vehicle are col-
lected through Toyota dealers. Do not dispose of the traction battery your-
self.
If the traction battery is not properly collected, the following may occur,
resulting in death or serious injury:
• The traction battery may be illegally disposed or dumped, and it is haz-
ardous to the environment. Additionally, someone may touch a high-volt-
age part, resulting in an electric shock.
• The traction battery is intended to be used exclusively with your fuel cell
vehicle. If the traction battery is used outside of your vehicle or modified
in any way, accidents, such as electric shock, heat generation, smoke
generation, ignition, explosion and electrolyte leakage may occur.
In particular, reselling or transferring the traction battery exposes the
receiving party to risks of accidents as they may not be aware of these
dangers. Make sure to inform them of the contents of this Owner’s Man-
ual.
● If your vehicle is disposed without the traction battery having been
removed, there is a danger of serious electric shock in case high-voltage
parts, cables, or their connectors are touched. When disposing of your
vehicle, the traction battery must be disposed by your Toyota dealer, or a
qualified service shop. If the traction battery is not disposed of properly, it
may cause electric shock that can result in death or serious injury.
NOTICE
■ Traction battery air intake vent
● If the traction battery output decreases due to the entry of dust or debris,
foreign material, a warning message is shown on the multi-information dis-
play. Have the vehicle inspected at your Toyota dealer.
● Do not place objects where the air intake vent will be obstructed. This may
lead to a reduction in traction battery power output and damage.
● Clean the air intake vent regularly to prevent clogging.
● Do not allow water or objects to enter the air intake vent, as this may dam-
age the traction battery.
■ Traction Battery
Do not spill a large amount of water near the traction battery in the vehicle.
If water spills onto the traction battery, have the vehicle inspected at your
Toyota dealer.

Advice for driving fuel cell vehicles
◆ Fuel cell system indicator usage
Maintaining the fuel cell system indicator to Eco area on the
multi-information display can extend your driving range. (P. 120)
◆ Accelerator pedal/brake pedal operation
Drive the vehicle smoothly. Avoid abrupt acceleration and decelera-
tion.
Mild acceleration and deceleration can help curb wasteful fuel con-
sumption.
◆ When braking
Make sure to depress the brake gently and allow for a long stopping
distance. This enables collection of more electrical energy gener-
ated during deceleration.
◆ Heavy traffic
Repeated acceleration and deceleration as well as long stops at
traffic lights, will decrease fuel economy. Check traffic reports
ahead of time and avoid traffic jams as much as possible. If caught
in a traffic jam, gently release the brake pedal to allow the vehicle to
move forward slowly while avoiding overuse of the accelerator
pedal to help curb wasteful fuel consumption.
◆ Driving with high power output
Similar to an electric vehicle, a fuel cell vehicle uses the most fuel in
high output driving such as driving on a steep uphill or at high
speeds. Moderate the vehicle speed and maintain a steady speed.
To maximize fuel economy and range, pay attention to the fol-
lowing:
103
2. Fuel cell vehicle

Fuel cell system
MIRAI_OM_USA_OM62054U(18MY)_O
M62048U(19MY)
◆ Using Eco drive mode
Using Eco drive mode (P. 195) makes torque generation less
aggressive than normal when stepping on the accelerator pedal,
leading to improvement in fuel economy.
Also, is displayed on the air conditioning screen, indicating
the switch to ECO HEAT/COOL mode (P. 308).
◆ Air conditioning system on/off
● Turn off the air conditioning system operation switch except
when necessary to help curb fuel consumption.
In summer: When the ambient temperature is high, use the recircu-
lated air mode. This decreases the load on the air con-
ditioning system.
In winter: Avoid excess heating. Use the seat heater to minimize
the need for cabin heating (P. 316).
● By pushing , ECO HEAT/COOL mode is turned on. This
helps curb fuel consumption even with the air conditioning system
turned on.
◆ Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. Improper
tire inflation pressure can cause poor fuel economy.
Additionally, snow tires have more rolling friction and their use on
dry roads lead to poor fuel economy. Use tires that are appropriate
for the season.
◆ Luggage
Avoid carrying unnecessary luggage and unload excess weight in
order avoid poor fuel economy. Installing a large roof rack will also
reduce fuel economy.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■ Before driving
● Make sure that the trunk lid is fully closed. If the trunk lid is not fully closed,
it may open unexpectedly while driving and hit near-by objects or luggage
in the trunk may be thrown out, causing an accident.
● Do not allow children to play in the trunk.
If a child is accidentally locked in the trunk, they could suffer from heat
exhaustion, suffocation or other injuries.
● Do not allow a child to open or close the trunk lid.
Doing so may cause the trunk lid to open unexpectedly, or cause the
child’s hands, head, or neck to be caught by the closing trunk lid.
■ Important points while driving
Never let anyone sit in the trunk. In the event of sudden braking or a colli-
sion, they are susceptible to death or serious injury.

WARNING
■ Using the trunk
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in seri-
ous injury.
● Remove any heavy loads, such as snow and ice, from the trunk lid before
opening it. Failure to do so may cause the trunk lid to suddenly shut again
after it is opened.
● When opening or closing the trunk lid, thoroughly check to make sure the
surrounding area is safe.
● If anyone is in the vicinity, make sure they are safe and let them know that
the trunk is about to open or close.
● Use caution when opening or closing the trunk lid in windy weather as it
may move abruptly in strong wind.
● Do not attach any accessories other than genuine Toyota parts to the trunk
lid. Such additional weight on the trunk lid may cause the lid to suddenly
shut again after it is opened.
● The trunk lid may suddenly shut if it is
not opened fully. It is more difficult to
open or close the trunk lid on an incline
than on a level surface, so beware of
the trunk lid unexpectedly opening or
closing by itself. Make sure that the
trunk lid is fully open and secure before
using the trunk.
● When closing the trunk lid, take extra
care to prevent your fingers, etc., from
being caught.
● When closing the trunk lid, make sure to
press it lightly on its outer surface. If the
trunk handle is used to fully close the
trunk lid, it may result in hands or arms
being caught.

■ Note for the entry function
● Even when the electronic key is within the effective range (detection areas),
the system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle, near
the ground, or in a high place when the doors are locked or unlocked.
• The electronic key is near the ground or in a high place, or too close to
the rear bumper center when the trunk is opened.
• The electronic key is on the instrument panel, rear package tray or floor,
or in the door pockets or glove box when the fuel cell system is started or
power switch modes are changed.
● Do not leave the electronic key on top of the instrument panel or near the
door pockets when exiting the vehicle. Depending on the radio wave recep-
tion conditions, it may be detected by the antenna outside the cabin and the
door will become lockable from the outside, possibly trapping the electronic
key inside the vehicle.
● As long as the electronic key is within the effective range, the doors may be
locked or unlocked by anyone. However, only the doors detecting the elec-
tronic key can be used to unlock the vehicle.
● Even if the electronic key is not inside the vehicle, it may be possible to start
the fuel cell system if the electronic key is near the window.
● The doors may unlock or lock if a large amount of water splashes on the
door handle, such as in the rain or in a car wash when the electronic key is
within the effective range. (The doors will automatically be locked after
approximately 60 seconds if the doors are not opened and closed.)
● If the wireless remote control is used to lock the doors when the electronic
key is near the vehicle, there is a possibility that the door may not be
unlocked by the entry function. (Use the wireless remote control to unlock
the doors.)
● Touching the door lock or unlock sensor while wearing gloves may prevent
lock or unlock operation.
● When the lock operation is performed using the lock sensor, recognition sig-
nals will be shown up to two consecutive times. After this, no recognition
signals will be given.
● If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In this case, follow the
following correction procedures to wash the vehicle:
• Place the electronic key in a location 6 ft. (2 m) or more away from the
vehicle. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart key
system. (P. 145)
● If the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, a message may be shown on the multi-information dis-
play and a buzzer will sound outside the vehicle. To turn off the alarm, lock
all the doors.

● The lock sensor may not work properly if it comes into contact with ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again.
● A sudden approach to the effective range or door handle may prevent the
doors from being unlocked. In this case, return the door handle to the origi-
nal position and check that the doors unlock before pulling the door handle
again.
● If there is another electronic key in the detection area, it may take slightly
longer to unlock the doors after the door handle is gripped.
■ When the vehicle is not driven for extended periods
● To prevent theft of the vehicle, do not leave the electronic key within 6 ft. (2 m)
of the vehicle.
● The smart key system can be deactivated in advance. (P. 486)
■ To operate the system properly
● Make sure to carry the electronic key when operating the system. Do not get
the electronic key too close to the vehicle when operating the system from the
outside of the vehicle.
Depending on the position and holding condition of the electronic key, the key
may not be detected correctly and the system may not operate properly. (The
alarm may go off accidentally, or the door lock prevention function may not
operate.)
● Do not leave the electronic key inside the trunk.
The key confinement prevention function may not operate, depending on
the location of the key (close to the emergency tire puncture repair kit, the
inside edge of the trunk), conditions (inside a metal bag, close to metallic
objects) and the radio waves in the surrounding area. (P. 140)
■ If the smart key system does not operate properly
● Locking and unlocking the doors and opening the trunk:
Use the mechanical key. (P. 449)

When the mirror select switch is in the “L” or “R” position, the outside
rear view mirrors will automatically angle downwards when the vehicle
is reversing in order to give a better view of the ground.
To disable this function, move the mirror select switch to the neutral
position (between “L” or “R”)
■ Adjusting the mirror angle when the vehicle is reversing
With the shift position in R, adjust the mirror angle at a desired posi-
tion.
The adjusted angle will be memorized and the mirror will automati-
cally tilt to the memorized angle whenever the shift position is
shifted to R from next time.
The memorized downward tilt position of the mirror is linked to the nor-
mal position (angle adjusted with the shift position in other than R).
Therefore, if the normal position is changed after adjustment, the tilt
position will also change.
When the normal position is changed, readjust the angle in reversing.
■ Mirror angle can be adjusted when
The power switch is in ACCESSORY or ON mode.
■ Rain clearing mirrors
The coating on the mirror has the rain clearing (hydrophilic) effect to make the
rear view clearer in raining. When water droplets collect on the mirror surface,
this effect causes the droplets to be spread out into a film.
● The rain clearing effect will be reduced temporarily, when the dirt is adhered
to the mirror or after your vehicle is parked for a long time in underground or
indoor parking lots, etc., where there is no direct sunlight.
However, the effect will gradually recover after 1- or 2-day exposure to direct
sunlight.
● If you want to restore the rain clearing effect immediately, conduct the resto-
ration work. (P. 353)
■ When the mirrors are fogged up
The outside rear view mirrors can be cleared using the mirror defoggers. Turn
on the rear window defogger to turn on the outside rear view mirror defog-
gers. (P. 309)

WARNING
■ Important points while driving
Observe the following precautions while driving.
Failure to do so may result in loss of control of the vehicle and cause an
accident, resulting in death or serious injury.
● Do not adjust the mirrors while driving.
● Do not drive with the mirrors folded.
● Both the driver and passenger side mirrors must be extended and properly
adjusted before driving.
■ When a mirror is moving
To avoid personal injury and mirror malfunction, be careful not to get your
hand caught by the moving mirror.
■ When the mirror defoggers are operating
Do not touch the rear view mirror surfaces, as they can become very hot
and burn you.
NOTICE
■ Handling the rain clearing mirror
The rain clearing effect is finite. Observe the following precautions in order
to retain the rain-clearing properties of the mirrors:
● When using water repellent, oil film remover, wax, or any other car mainte-
nance product that contains silicone, pay full attention not to adhere it to
the mirror surface.
● Do not wipe the mirror surface by using any cloth smeared with sand, oil
film remover, abrasive agent, or any other thing that may scratch the mir-
ror surface.
● When the mirrors become iced up, remove the ice by applying warm
water, or operating the outside rear view mirror defoggers.
But, do not attempt to scrape the ice off by using the plastic plate, etc.
● When washing your vehicle using car shampoo with water repellent effect,
rinse the mirror surface with a lot of water, and remove the water drops by
using a clean and soft cloth.

■ When starting off on an uphill
The hill-start assist control will activate. (P. 295)
■ For fuel-efficient driving
Keep in mind that fuel cell vehicles are similar to conventional vehicles, and it
is necessary to refrain from activities such as sudden acceleration. (P. 102)
■ Driving in the rain
● Drive carefully when it is raining, because visibility will be reduced, the win-
dows may become fogged-up, and the road will be slippery.
● Drive carefully when it starts to rain, because the road surface will be espe-
cially slippery.
● Refrain from high speeds when driving on an expressway in the rain,
because there may be a layer of water between the tires and the road sur-
face, preventing the steering and brakes from operating properly.
■ Restraining the fuel cell system output (Brake Override System)
● When the accelerator and brake pedals are depressed at the same time, the
fuel cell system output may be restrained.
● A warning message is displayed on the multi-information display while the
system is operating. If a warning message is shown on the multi-information
display, read the message and follow the instructions.
■ Restraining sudden start (Drive-Start Control)
● When the following unusual operation is performed, the fuel cell system out-
put may be restrained.
• When the shift lever is shifted from R to D, D to R, N to R, P to D, or P to
R with the accelerator pedal depressed, a warning message appears on
the multi-information display. If a warning message is shown on the multi-
information display, read the message and follow the instructions.
• When the accelerator pedal is depressed too while the vehicle is in
reverse.
● While Drive-Start Control is being activated, your vehicle may have trou-
ble escaping from the mud or fresh snow. In such case, deactivate TRAC
(P. 296) to cancel Drive-Start Control so that the vehicle may become
able to escape from the mud or fresh snow.

■ Breaking in your new Toyota
To extend the life of the vehicle, observing the following precautions is recom-
mended:
● For the first 200 miles (300 km):
Avoid sudden stops.
● For the first 1000 miles (1600 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive at a constant speed for extended periods.
■ Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of brake
system needs bedding-down of the brake shoes periodically or whenever the
parking brake shoes and/or drum are replaced. Have your Toyota dealer per-
form the bedding down operation.
■ Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. (P. 468)

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 “READY”
indicator is illuminated. 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 difficulty
in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the
vehicle only slightly. This allows you to depress the brake and accelera-
tor pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake
pedal using your left foot may delay response in an emergency, result-
ing in an accident.
● The driver should pay extra attention to pedestrians when the fuel cell sys-
tem is on. As there are no engine sounds, pedestrians may misjudge the
vehicle’s movement.
● During normal driving, do not turn off the fuel cell system. Turning the fuel
cell system off while driving will not cause loss of steering or braking con-
trol, however, power assist to the steering will be lost. This will make it
more difficult to steer smoothly, so you should pull over and stop the vehi-
cle as soon as it is safe to do so.
In the event of an emergency, such as if it becomes impossible to stop the
vehicle in the normal way: P. 409
● Do not adjust the positions of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control.
● Always check that all passengers’ arms, heads or other parts of their body
are not outside the vehicle.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■ When driving the vehicle
● Do not drive in excess of the speed limit. Even if the legal speed limit per-
mits it, do not drive over 85 mph (140 km/h) unless your vehicle has high-
speed capability tires. Driving over 85 mph (140 km/h) may result in tire
failure, loss of control and possible injury. Be sure to consult a tire dealer
to determine whether the tires on your vehicle are high-speed capability
tires or not before driving at such speeds.
■ When driving on slippery road surfaces
● Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle.
● Sudden acceleration or regenerative braking due to shifting 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 changing the shift position
● Do not let the vehicle roll backward while a forward driving position is
selected, or roll forward while the shift position is in R.
Doing so may result in an accident or damage to the vehicle.
● Do not shift the shift position to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle
control.
● Do not shift the shift position to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
● Do not shift the shift position to a driving position while the vehicle is mov-
ing backward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
● Shifting the shift position to N while the vehicle is moving will disengage
the fuel cell system. Regenerative braking is not available with the fuel cell
system disengaged.
● Be careful not to shift the shift position with the accelerator pedal
depressed. Shifting the shift position to any position other than P or N may
lead to unexpected rapid acceleration of the vehicle that may cause an
accident and result in death or serious injury.
After shifting the shift position, make sure to check the current shift posi-
tion using the shift position indicator. (P. 193)

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■ If you hear a squealing or scraping noise (brake pad wear limit indica-
tors)
Have the brake pads checked and replaced by your Toyota dealer as soon
as possible.
Rotor damage may result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads
and/or those of the brake discs are exceeded.
■ When the vehicle is stopped
● Do not depress the accelerator pedal unnecessarily.
If the shift position is in any position other than P or N, the vehicle may
accelerate suddenly and unexpectedly, causing an accident.
● In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while stopped with the “READY” indicator is
illuminated, and apply the parking brake as necessary.
● If the vehicle is stopped on an incline, in order to prevent accidents caused
by the vehicle rolling forward or backward, always depress the brake pedal
and securely apply the parking brake as needed.
■ 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 rupture, causing the contents to spray over the
interior of the vehicle, and may also cause a short circuit in the vehicle’s
electrical components.
● Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a
place such as the glove box or on the floor, it may be lit accidentally when
luggage is loaded or the seat is adjusted, causing a fire.
● Do not attach adhesive discs to the windshield or windows. Do not place
containers such as air fresheners on the instrument panel or dashboard.
Adhesive discs or containers may act as lenses, causing a fire in the vehi-
cle.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■ When the vehicle is parked
● Do not leave a door or window open if the curved glass is coated with a
metallized film such as a silver-colored one. Reflected sunlight may cause
the glass to act as a lens, causing a fire.
● Always apply the parking brake, shift the shift position to P, stop the fuel
cell system and lock the vehicle.
Do not leave the vehicle unattended while the “READY” indicator is illumi-
nated.
If the vehicle is parked with the shift position in P but the parking brake is
not set, the vehicle may start to move, possibly leading to an accident.
■ When taking a nap in the vehicle
Always turn the fuel cell system off. Otherwise, if you accidentally move the
shift lever or depress the accelerator pedal, causing the vehicle to uninten-
tionally move, which can lead to an accident, resulting 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 electronically controlled brake system does not operate, do not fol-
low other vehicles closely and avoid hills or sharp turns that require brak-
ing.
In this case, braking is still possible, but the brake pedal should be
depressed more firmly than usual. Also, the braking distance will increase.
Have your brakes fixed immediately.
● The brake system consists of 2 or more individual hydraulic systems; if
one of the systems fails, the other(s) will still operate. In this case, the
brake pedal should be depressed more firmly than usual and the braking
distance will increase. Have your brakes fixed immediately.
NOTICE
■ When driving the vehicle
● Do not depress the accelerator and brake pedals at the same time during
driving, as this may restrain the fuel cell system output.
● Do not use the accelerator pedal or depress the accelerator and brake
pedals at the same time to hold the vehicle on a hill.
■ When parking the vehicle
Always set the parking brake, and shift the shift position to P. Failure to do
so may cause the vehicle to move or the vehicle may accelerate suddenly if
the accelerator pedal is accidentally depressed.

NOTICE
■ Avoiding damage to vehicle parts
● Do not turn the steering wheel fully in either direction and hold it there for
an extended period of time.
Doing so may damage the power steering motor.
● When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.
■ If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehi-
cle.
● It may be difficult to control your vehicle.
● The vehicle will make abnormal sounds or vibrations.
● The vehicle will lean abnormally.
Information on what to do in case of a flat tire (P. 432)
■ 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:
● Fuel cell system stalling
● Short in electrical components
● Fuel cell system 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:
● Fuel cell system
● Brake function
● Changes in quantity and quality of transmission fluid, etc.
● Lubricant condition for the bearings and suspension joints (where possi-
ble), and the function of all joints, bearings, etc.
If the shift control system is damaged by flooding, it may not be possible to
shift the shift position to P, or from P to other positions. When the shift posi-
tion cannot be changed from P to any other position, the front wheels will
lock, and you will be unable to tow the vehicle with the front wheels on the
ground, as the front wheels may be locked. In this case, transport the vehi-
cle with both front wheels or all four wheels lifted.
■ If the vehicle will not shift out of the P position
There is a possibility that the 12-volt battery is discharged. Check the
12-volt battery in this situation.

Cargo and luggage
Cargo capacity depends on the total weight of the occupants.
(Cargo capacity) = (Total load capacity) — (Total weight of occupants)
Steps for Determining Correct Load Limit —
(1) Locate the statement “The combined weight of occupants and
cargo should never exceed XXX kg or XXX lbs.” on your vehicle’s
placard.
(2) Determine the combined weight of the driver and passengers that
will be riding in your vehicle.
(3) Subtract the combined weight of the driver and passengers from
XXX kg or XXX lbs.
(4) The resulting figure equals the available amount of cargo and lug-
gage load capacity.
For example, if the “XXX” amount equals 1400 lbs. and there will be
five 150 lb passengers in your vehicle, the amount of available
cargo and luggage load capacity is 650 lbs. (1400 750 (5150) =
650 lbs.)
(5) Determine the combined weight of luggage and cargo being loaded
on the vehicle. That weight may not safely exceed the available
cargo and luggage load capacity calculated in Step 4.
(6) If your vehicle will be towing a trailer, load from your trailer will be
transferred to your vehicle. Consult this manual to determine how
this reduces the available cargo and luggage load capacity of your
vehicle.
(P. 183)
Toyota does not recommend towing a trailer with your vehicle. Your
vehicle is not designed for trailer towing.
Take notice of the following information about storage precau-
tions, cargo capacity and load.

Cargo capacity
Total load capacity (vehicle
capacity weight) (P. 466)
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
■ Caution regarding the use of windshield wipers in “AUTO” mode
The windshield wipers may operate unexpectedly if the sensor is touched or
the windshield is subject to vibration in “AUTO” mode. Take care that your
fingers, etc., do not become caught in the windshield wipers.
■ Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes
warm. The fluid may freeze on the windshield and cause low visibility. This
may lead to an accident, resulting in death or serious injury.

● Turn the power switch off.
● Turn off the headlights.
■ Fuel Type
Compressed hydrogen gas
■ Notes on fueling
● Fueling will not be possible if the pressure inside the vehicle’s hydrogen tanks
is higher than the supply pressure of the hydrogen station. If the hydrogen
tanks are more than half full, the vehicle will be unable to fuel at a H35 dis-
penser.
A hydrogen station with a H70 dispenser (supply pressure of 10150 psi
[70 MPa, 714 kgf/cm
2
, 700 bar] is necessary to completely fill hydrogen tanks.
● If the fueling cannot be completed due to trouble with the station equipment,
call the number indicated on the equipment.
● Fuel with compressed hydrogen gas only at hydrogen stations.
● Fuel at hydrogen stations conforming with the Society of Automo-
tive Engineers (SAE) J2601 fueling protocol or laws that may
supersede such SAE protocols.
●
Refer to the Mirai Station Finder Application in Entune,
www.toyota.com
(for U.S. owners) or www.toyota.ca (for
Canadian owners), or call 1-800-331-4331 (for U.S. owners)
or 1-888-869-6828 (for Canadian owners).
● Observe any notices or instructions shown at hydrogen stations.
● The filling time and amount of fuel may depend on outside tem-
perature and the equipment at that hydrogen station.
● Vehicles with expired hydrogen tanks must not be used. (P. 9 4 )
Consult your Toyota dealer.

WARNING
■ When filling
Observe the following precautions while fueling the vehicle.
Failure to do so may result in death or serious injury.
● Turn the power switch off before fueling.
● Ensure the hydrogen gas nozzle is locked onto the vehicle receptacle
before filling. This can be done by pulling on the hydrogen gas nozzle to
check that it cannot be pulled off.
Failure to do so may result in injury or damage to the hydrogen gas nozzle
or vehicle.
● Do not smoke while fueling.
● Because the fuel is cold, the hydrogen gas nozzle and vehicle receptacle
surface will become cold, and frost may develop. After fueling is com-
pleted, remove the hydrogen gas nozzle by the plastic handle only. Do not
touch any other parts of the hydrogen gas nozzle or vehicle receptacle
with bare hands immediately after fueling, as frostbite may occur.
NOTICE
■ When filling
● Fuel only with compressed hydrogen gas at stations compliant with the
Society of Automotive Engineers (SAE) J2601 fueling protocol or laws that
may supersede such SAE protocols.
If improper fuels are used, the fuel cell stack will be damaged.
● Do not swing or drop the hydrogen gas nozzle, or subject it to a large
amount of force. Doing so may cause damage.
● If the hydrogen gas nozzle cannot be removed after fueling, it may be fro-
zen to the vehicle receptacle. Wait for the hydrogen gas nozzle to thaw
before attempting to remove. Do not pull or rotate the hydrogen gas nozzle
forcibly. Failure to follow these precautions may cause damage.
● Be sure to replace the cap after filling. If foreign material gets in the vehicle
receptacle, it may cause damage.
● Do not put anything sharp, such as a screwdriver, blade, or any foreign
object into the mouth of the vehicle receptacle. If the vehicle receptacle is
damaged, hydrogen gas may leak during fueling.
● If you notice anything unusual about the vehicle receptacle, please notify
your Toyota dealer.
● If you notice anything unusual with the hydrogen dispenser or hydrogen
gas nozzle, please notify the hydrogen station operator. Contact informa-
tion is usually displayed on the dispenser.

Situation Actions
When the area around a sensor is
covered with dirt, moisture (fogged
up, covered with condensation, ice,
etc.), or other foreign matter
To clean the part of the windshield in
front of the front camera, use the
windshield wipers or the windshield
defogger of the air conditioning sys-
tem (P. 309)
When the temperature around the
front camera is outside of the opera-
tional range, such as when the vehi-
cle is in the sun or in an extremely
cold environment
If the front camera is hot, such as
after the vehicle had been parked in
the sun, use the air conditioning sys-
tem to decrease the temperature
around the front camera.
If a sunshade was used when the
vehicle was parked, depending on its
type, the sunlight reflected from the
surface of the sunshade may cause
the temperature of the front camera
to become excessively high.
If the front camera is cold, such after
the vehicle is parked in an extremely
cold environment, use the air condi-
tioning system to increase the tem-
perature around the front camera.
The area in front of the front camera
is obstructed, such as when the hood
is open or a sticker is attached to the

PCS (Pre-Collision system)
The system can detect the following:
● Vehicles
● Bicyclists
● Pedestrians
The pre-collision system uses a radar sensor and front camera
to detect objects (P. 226) in front of the vehicle. When the sys-
tem determines that the possibility of a frontal collision with an
object is high, a warning operates to urge the driver to take eva-
sive 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 an object is extremely high,
the brakes are automatically 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. 230)

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
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 impact of the collision.

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 sys-
tem 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 serious injury.
● Although this system is designed to help avoid a collision or help reduce
the impact of the collision, its effectiveness may change according to vari-
ous conditions, therefore the system may not always be able to achieve
the same level of performance.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• Conditions under which the system may operate even if there is no pos-
sibility of a collision: P. 233
• Conditions under which the system may not operate properly: P. 235
● 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.

LDA (Lane Departure Alert with steering
control)
When driving on highways and freeways with white (yellow) lane
lines, this function alerts the driver when the vehicle might depart from
its lane or course
* and provides assistance by operating the steering
wheel to keep the vehicle in its lane or course
*.
The LDA system recognizes white
(yellow) lane lines or a course
*
using the front camera. Addition-
ally, it detects preceding vehicles
using the front camera and radar.
*: Boundary between asphalt and the
side of the road, such as grass, soil,

Summary of functions
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.
● When not using the LDA system, use the LDA switch to turn the system
off.
■ Situations unsuitable for LDA system
In the following situations, use the LDA switch to turn the system off. Failure
to do so may lead to an accident, resulting in death or serious injury.

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. 263
• Conditions under which the vehicle-to-vehicle distance control mode
may not function correctly: P. 2 64
● 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 setting to off, using the “ON-OFF”
button when not in use.
■ 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 driver’s own vehicle and a
designated vehicle traveling ahead. It is not a mechanism that allows
careless or inattentive driving, and it is not a system that can assist the
driver in low-visibility conditions.
It is still necessary for driver to pay close attention to the vehicle’s sur-
roundings.

WARNING
● 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
prevent or avoid collisions with vehicles ahead of your vehicle. Therefore,
if there is ever any possibility of danger, the driver must take immediate
and direct control of the vehicle and act appropriately in order to ensure
the safety of all involved.
■ 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 or front
camera
● In traffic conditions that require frequent repeated acceleration and decel-
eration
● During emergency towing
● When an approach warning buzzer is heard often

This mode employs a radar 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 suitable fol-
lowing distance from the vehicle ahead. The desired vehicle-to-vehi-
cle distance can also be set by operating the vehicle-to-vehicle
distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distance may
become shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system applies the brakes (the stop lights will come on at
this time).
The system will respond to changes in the speed of the vehicle ahead in
order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the turn signal lever is operated and your vehicle moves to a left
lane while driving at 50 mph (80 km/h) or more, the vehicle will quickly

■ Sensor detection information
● The sensor’s detection areas are limited to the areas around the vehicle’s
bumper.
● 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
vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• A backlit license plate, license plate holder, etc., are installed.
• The vehicle is approaching a tall or curved curb.
• 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.
• People may not be detected if they are wearing certain types of clothing.
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.
● The shape of the obstacle may prevent a sensor from detecting it. Pay par-
ticular attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of
your vehicle
271
5-5. Using the driving support systems

Driving
MIRAI_OM_USA_OM62054U(18MY)_O
M62048U(19MY)
● The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection
distance 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
sensor’s detection areas before the display is shown and the buzzer
sounds.
• Thin posts or objects lower than the sensor may not be detected when
approached, even if they have been detected once.
• It might be difficult to hear beeps due to the volume of audio system or air
flow noise of the air conditioning system.
■ Muting the buzzer sound
● To mute the buzzer sound
The buzzer can be temporarily muted by pressing of the meter control
switches while an obstacle detection display is shown on the multi-informa-
tion display.
● To cancel the mute
Mute will be automatically canceled in the following situations.
• When the shift position is changed
• When the vehicle speed has reached or exceeded approximately 6 mph
(10 km/h)
• When the intuitive parking assist is turned off once and turned on again
• When the power switch is turned off once and turned to ON mode again
• When a sensor is malfunctioning
■ If “Parking Assist Unavailable Clean Parking Assist Sensor” is displayed
on the multi-information display
A sensor may be dirty or covered with snow or ice. In such cases, if it is
removed from the sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a malfunction dis-
play may appear or an obstacle may not be detected. If the sensor thaws out,
the system should return to normal.
■ If “Parking Assist Malfunction Visit Your Dealer” is displayed on the
multi-information display
Depending on the malfunction of the sensor, the device may not be working
normally.
Have the vehicle inspected by your Toyota dealer.

WARNING
■ When using the intuitive parking assist
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be driven safely
and possibly cause an accident.
● Do not use the sensor at speeds in excess of 6 mph (10 km/h).
● The sensors’ detection areas and reaction times are limited. When moving
forward or reversing, check the areas surrounding the vehicle (especially
the sides of the vehicle) for safety, and drive slowly, using the brake to
control the vehicle’s speed.
● Do not install accessories within the sensors’ detection areas.
NOTICE
■ When using intuitive parking assist
In the following situations, the system may not function correctly due to a
sensor malfunction, etc. Have the vehicle checked by your Toyota dealer.
● The intuitive parking assist operation display flashes, and a buzzer sounds
when no obstacles are detected.
● If the area around a sensor collides with something, or is subjected to
strong impact.
● If the bumper collides with something.
● If the display shows continuously without beeping, except when the buzzer
mute switch has been turned on.
● If a display error occurs, first check the sensor.
If the error occurs even if there is no ice, snow or mud on the sensor, it is
likely that the sensor is malfunctioning.

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

■ Sensor detection range
The detection range of the Parking Support Brake function (for static objects)
differs from the detection range of the intuitive parking assist (P. 269).
Therefore, even if the intuitive parking assist detects and provides a warning
for an approaching obstacle, the Parking Support Brake function (for static
objects) may not start operating.
■ System operation
When the vehicle is stopped by system operation, the Parking Support Brake
function (for static objects) stops and the PKSB OFF indicator illuminates.
Even if operated, the brake control is released after 2 seconds, so the vehicle
can start moving in that state. Also, depressing the brake pedal releases the
brake control, so if the accelerator pedal is depressed again, the vehicle can
start moving.
■ System recovery
When the Parking Support Brake function (for static objects) is stopped by the
system operation and you would like to resume operation, turn the Parking
Support Brake function (for static objects) ON again and resume operation
(P. 276), or after briefly turning the power switch OFF turn it ON again.
Furthermore, when the vehicle moves with an obstacle no longer in the trav-
eling direction of the vehicle, or when the traveling direction of the vehicle
changes (such as when switching from moving forward to reverse, and vice
versa), the system operation automatically resumes.
■ Obstacles not detected by the sensors
The following obstacles may not be detected by the sensors.
● Objects such as people, cloth and snow, that are difficult for sonic waves to
reflect off of. (In particular, people may also not be detected depending on
the type of clothing they are wearing.)
● Objects not perpendicular with the ground, objects not at a right angle to the
traveling direction of the vehicle, uneven objects or waving objects
● Low objects
● Thin objects such as wires, fences, ropes and signposts
● Objects that are extremely close to the bumper
● Non-static obstacles
■ Intuitive parking assist buzzer
Regardless of whether the intuitive parking assist is on or off (P. 266), if the
Parking Support Brake function (for static objects) is not stopped (P. 276),
when the front or rear sensors detect an obstacle and brake control is per-
formed, the intuitive parking assist buzzer sounds and a notification of the
approximate distance to the object is provided.

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

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

WARNING
■ For safe use
Do not rely solely upon the system. Relying solely upon the system may
lead to an unexpected accident.
● Driving safely is the sole responsibility of the driver. Pay careful attention
to the surrounding conditions in order to ensure safe driving. The Parking
Support Brake function (for static objects) can provide support to lessen
the severity of collisions. However, it may not operate depending on the
situation.
● The Parking Support Brake function (for static objects) is not a system
designed to completely stop the vehicle. Furthermore, even if the brake
control is able to stop the vehicle, brake control is canceled after approxi-
mately 2 seconds, so depress the brake pedal immediately.
■ In order for the system to operate properly
Make sure to observe the following precautions regarding the sensors
(P. 265). Failure to observe these precautions may cause the sensors
not to operate properly, and may result in an unexpected accident.
● Do not perform work such as modification, disassembly or painting
● Only perform replacements using genuine parts
● Do not subject the area around the sensors to any impacts
● Do not damage the sensors, and always keep them clean
■ Handling the suspension
Do not modify the suspension, as changes to the height or incline of the
vehicle may prevent the sensors from correctly detecting obstacles, may
cause the system not operate, or may cause the system to operate unnec-
essarily.

Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to road con-
ditions.
Park the vehicle and shift the shift position to P without setting the
parking brake. The parking brake may freeze up, preventing it from
being released. If the vehicle is parked without setting the parking
brake, make sure to block the wheels.
Failure to do so may be dangerous because it may cause the vehicle
to move unexpectedly, possibly leading to an accident.
Use the correct tire chain size when mounting the tire chains.
Chain size is regulated for each tire size.
Side chain:
0.12 in. (3 mm) in diameter
0.39 in. (10 mm) in width
1.18 in. (30 mm) in length
Cross chain:
0.16 in. (4 mm) in diameter
0.55 in. (14 mm) in width
0.98 in. (25 mm) in length
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.

WARNING
■ Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
● Use tires of the specified size.
● Maintain the recommended level of air pressure.
● Do not drive in excess of 75 mph (120 km/h), regardless of the type of
snow tires being used.
● Use snow tires on all, not just some wheels.
■ Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
● Do not drive in excess of the speed limit specified for the tire chains being
used, or 30 mph (50 km/h), whichever is lower.
● Avoid driving on bumpy road surfaces or over potholes.
● Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden regenerative braking.
● Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
● Do not use LDA (Lane Departure Alert with steering control) system.
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

■ Fogging up of the windows
● The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the wind-
shield effectively.
● If you turn off, the windows may fog up more easily.
● The windows may fog up if the recirculated air mode is used.
■ Windshield fog detection function
When automatic mode is set, the humidity sensor (P. 314) detects fog on
the windshield and controls the air conditioning system to prevent fog.
■ Outside/recirculated air mode
● When driving on dusty roads such as tunnels or in heavy traffic, set the out-
side/recirculated air mode button to recirculated air mode. This is effective in
preventing outside air from entering the vehicle interior. During cooling oper-
ation, setting the recirculated air mode will also cool the vehicle interior
effectively.
● Outside/recirculated air mode may automatically switch depending on the
temperature setting or the inside temperature.
■ Operation of the air conditioning system in ECO HEAT/COOL mode
● In ECO HEAT/COOL mode, the air conditioning system is controlled as fol-
lows to prioritize fuel efficiency:
• Fluid (heating) heater and compressor operation controlled to restrict
heating/cooling capacity
• Fan speed restricted when automatic mode is selected
● To improve air conditioning performance, perform the following operations:
• Adjust the temperature settings and fan speed
• Touch while in , and is set
• Touch while in , and ECO HEAT/COOL mode is canceled
■ Operation of the air conditioning system in Eco drive mode
When “ECO MODE” switch is pressed, operations switch over to ECO HEAT/
COOL mode. (P. 197)
■ 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 power switch
is turned to ON mode.
● It is possible to switch to outside air mode at any time by pressing .

■ Ventilation and air conditioning odors
● To let fresh air in, set the air conditioning system to the outside air mode.
● During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.
● To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic

Maintenance and care
Your vehicle is equipped with a tire pressure warning system that uses
tire pressure warning valves and transmitters to detect low tire infla-
tion pressure before serious problems arise.
If the tire pressure drops below a predetermined level, the driver is
warned by a warning light. (P. 421)
◆ 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 valves and transmitter ID
codes registered by your Toyota dealer. (P. 379)
◆ Registering ID codes
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to register the ID code. Have the ID code
registered by your Toyota dealer.

■ When to replace your vehicle’s tires
Tires should be replaced if:
● The treadwear indicators are showing on a tire.
● You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric, and bulges indicating internal damage
● A tire goes flat repeatedly or cannot be properly repaired due to the size
or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
■ Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not reg-
istered, the tire pressure warning system will not work properly. After driv-
ing for about 20 minutes, the tire pressure warning light blinks for 1
minute and stays on to indicate a system malfunction.
■ Tire life
Any tire over 6 years old must be checked by a qualified technician even
if it has seldom or never been used or damage is not obvious.
■ Routine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation
pressure checks. Make sure to check tire inflation pressure as part of
your routine of daily vehicle checks.
■ Maximum load of tire
Check that the maximum load of the replacement tire is greater than 1/2
of the Gross Axle Weight Ratings (GAWR) of either the front axle or the
rear axle, whichever is greater.
For the GAWR, see the Certification
Label. For the maximum load of the tire,
see the load limit at maximum cold tire
inflation pressure mentioned on the
sidewall of the tire. (P. 472)

Maintenance and care
■ Tire types
● Summer tires
Summer tires are high-speed performance tires best suited to highway
driving under dry conditions. Since summer tires do not have the same
traction performance as snow tires, summer tires are inadequate for
driving on snow-covered or icy roads. For driving on snow-covered
roads or icy roads, the use of snow tires is recommended. When install-
ing snow tires, be sure to replace all four tires.
● All season tires
All season tires are designed to provide better traction in snow and to
be adequate for driving in most winter conditions as well as for use
year-round. All season tires, however, do not have adequate traction
performance compared with snow tires in heavy or loose snow. Also, all
season tires fall short in acceleration and handling performance com-
pared with summer tires in highway driving.
● Snow tires
For driving on snow-covered roads or icy roads, we recommend using
snow tires. If you need snow tires, select tires of the same size, con-
struction and load capacity as the originally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tires without
first checking local regulations for possible restrictions. Snow tires
should be installed on all wheels. (P. 301)
■ If the tread on snow tires wears down below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is lost.

WARNING
■ Replacing a 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.
● 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 the wheel nuts with
the tapered ends facing inward. (P. 397)

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

Wheels
When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim width and
inset
*.
Replacement wheels are available at your Toyota dealer.
*: Conventionally referred to as “offset”.
Toyota does not recommend using the following:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
● Use only Toyota wheel nuts and wrenches designed for use with
your aluminum wheels.
● When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).
● Be careful not to damage the aluminum wheels when using tire
chains.
● Use only Toyota genuine balance weights or equivalent and a plas-
tic or rubber hammer when balancing your wheels.
■ When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning
valves and transmitters that allow the tire pressure warning system to
provide advance warning in the event of a loss in tire inflation pressure.
Whenever wheels are replaced, tire pressure warning valves and trans-
mitters must be installed. (P. 379)
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.

When trouble arises
If your vehicle is transported by a
flatbed truck, it should be tied
down at the locations shown in the
illustration.
If you use chains or cables to tie
down your vehicle, the angles
shaded in black must be 45.
Do not overly tighten the tie
downs or the vehicle may be dam-
aged.
If a tow truck is not available in an emergency, your vehicle may be
temporarily towed using cables or chains secured to the emergency
towing eyelets. This should only be attempted on hard surfaced roads
for a short distance at under 18 mph (30 km/h).
A driver must be in the vehicle to steer and operate the brakes. The
vehicle’s wheels, drivetrain, axles, steering and brakes must be in
good condition.

When trouble arises
■ While towing
If the fuel cell system is off, the power assist for the brakes and steering will
not function, making steering and braking more difficult.
■ Wheel nut wrench
Wheel nut wrench is installed in trunk. (P. 386434)
■ Before transporting or towing in frozen areas
Operate the water release function. Otherwise, the fuel cell system may
freeze and the vehicle may not be able to be started. (P. 190)
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■ When towing the vehicle
■ While towing
● When towing using cables or chains, avoid sudden starts, etc., which
place excessive stress on the towing eyelets, cables or chains. The towing
eyelets, cables or chains may become damaged, broken debris may hit
people, and cause serious damage.
● Do not turn the power switch off.
This may lead to an accident as the front wheels will be locked by the
parking lock.
■ Installing towing eyelets to the vehicle
Make sure that towing eyelets are installed securely.
If not securely installed, towing eyelets may come loose during towing.
Be sure to transport the vehicle with the
front wheels raised or with all four wheels
raised off the ground. If the vehicle is
towed with the front wheels contacting
the ground, the drivetrain and related
parts may be damaged or electricity gen-
erated by the operation of the motor may
cause a fire to occur depending on the
nature of the damage or malfunction.

■ Warning buzzer
In some cases, the buzzer may not be heard due to being in a noisy location
or audio sound.
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
When the light comes on yellow, the assist to the power steering is
restricted. When the light comes on red, the assist to the power steering is
lost and handling operations of the steering wheel become extremely

■
If the tire pressure warning light comes on
Handling method (P. 423)
Be sure to observe the following precautions. Failure to do so could
cause a loss of vehicle control and result in death or serious injury.
● Stop your vehicle in a safe place as soon as possible. Adjust the tire
inflation pressure immediately.
● If the tire pressure warning light comes on even after tire inflation pres-
sure adjustment, it is probable that you have a flat tire. Check the tires.
If a tire is flat, repair the flat tire by using emergency tire puncture
repair kit.
● Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate,
you could lose control of the steering wheel or the brakes.
■ If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.

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.

If you have a flat tire
Your vehicle is not equipped with a spare tire, but instead is
equipped with an emergency tire puncture repair kit.
A puncture caused by a nail or screw passing through the tire
tread can be repaired temporarily using the emergency tire
puncture repair kit. (The kit contains a bottle of sealant. The
sealant can be used only once to temporarily repair one tire
without removing the nail or screw from the tire.)
After temporarily repairing the tire with the repair kit, have the
tire repaired or replaced by your Toyota dealer.
WARNING
■ If you have a flat tire
Do not continue driving with a flat tire.
Driving, even a short distance, with a flat tire can damage the tire, the
wheel, and other parts beyond repair, which could result in an accident.

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

● In some cases, it may not be possible to unlock the doors using the smart
key system when the 12-volt battery is discharged. Use the wireless remote
control or the mechanical key to lock or unlock the doors.
● The fuel cell system may not start on the first attempt after the 12-volt bat-
tery has recharged but will start normally after the second attempt. This is
not a malfunction.
● The power switch mode is memorized by the vehicle. When the 12-volt bat-
tery is reconnected, the system will return to the mode it was in before the
12-volt battery was discharged. Before disconnecting the 12-volt battery,
turn the power switch off.
If you are unsure what mode the power switch was in before the 12-volt bat-
tery discharged, be especially careful when reconnecting the 12-volt battery.
● If the 12-volt battery is depleted with the shift position in P, it will not be pos-
sible to shift the shift position other than P. In this case, the vehicle cannot
be towed without lifting both front wheels because the front wheels are
locked by the parking lock. (P. 412)

When trouble arises
● When the 12-volt battery is reconnected, start the fuel cell system, depress
the brake pedal, and confirm that it is possible to shift into each shift posi-
tion.
● If the battery is removed or the terminals disconnected without operating the
water release function during cold weather, the vehicle may not start due to
the fuel cell system being frozen. To prevent this, operate the water release
function before removing the battery or disconnecting the terminals.
(P. 190)
■ When exchanging the 12-volt battery
Use a Central Degassing type 12-volt battery (Japanese Industrial Stan-
dards). Also, use 12-volt batteries with case sizes similar to one prior the
exchange and an equivalent 20 hour rate capacity (20HR) or greater.
• If the sizes differ, the 12-volt battery cannot be properly secured.
• If the 20 hour rate capacity is low, even if the time period where the vehicle
is not used is a short time, the 12-volt battery may discharge and fuel cell
system may not be able to start.
For details, consult your Toyota dealer.
WARNING
■ Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the 12-volt battery:
● Make sure each jumper cable is connected to the correct terminal and that
it is not unintentionally in contact with any other than the intended terminal.
● Do not allow the other end of the jumper cable connected to the “+” termi-
nal to come into contact with any other parts or metal surfaces in the area,
such as brackets or unpainted metal.
● Do not allow the + and - clamps of the jumper cables to come into contact
with each other.
● Do not smoke, use matches, cigarette lighters or allow open flame near
the 12-volt battery.

WARNING
■ 12-volt battery precautions
The 12-volt battery contains poisonous and corrosive acidic electrolyte,
while related parts contain lead and lead compounds. Observe the following
precautions when handling the 12-volt battery:
● When working with the 12-volt battery, always wear safety glasses and
take care not to allow any 12-volt battery fluids (acid) to come into contact
with skin, clothing or the vehicle body.
● Do not lean over the 12-volt battery.
● In the event that 12-volt battery fluid comes into contact with the skin or
eyes, immediately wash the affected area with water and seek medical
attention.
Place a wet sponge or cloth over the affected area until medical attention
can be received.
● Always wash your hands after handling the 12-volt battery support, termi-
nals, and other battery-related parts.
● Do not allow children near the 12-volt battery.
■ After recharging the 12-volt battery
Have the 12-volt battery inspected at your Toyota dealer as soon as possi-
ble.
If the 12-volt battery is deteriorating, continued use may cause the 12-volt
battery to emit a malodorous gas, which may be detrimental to the health of
passengers.
■ When exchanging the 12-volt battery
After exchanging, securely attach the exhaust hose and exhaust hole plug
to the exhaust hole of the exchanged 12-volt battery. If not properly
installed, gases (hydrogen) may leak into the vehicle interior, and there is
the possible danger of the gas igniting and exploding.
■ When replacing the 12-volt battery
P. 376
NOTICE
■ To prevent damaging the vehicle
The exclusive jump starting terminal is to be used when charging the 12-volt
battery from another vehicle in an emergency. It cannot be used to jump
start another vehicle.
■ When handling jumper cables
When connecting the jumper cables, ensure that they do not become entan-
gled in the cooling fans.

This information has been prepared in accordance with regulations
issued by the National Highway Traffic Safety Administration of the
U.S. Department of Transportation.
It provides the purchasers and/or prospective purchasers of Toyota
vehicles with information on uniform tire quality grading.
Your Toyota dealer will help answer any questions you may have as
you read this information.
■ DOT quality grades
All passenger vehicle tires must conform to Federal Safety Require-
ments in addition to these grades. Quality grades can be found
where applicable on the tire sidewall between tread shoulder and
maximum section width.
For example: Treadwear 200 Traction AA Temperature A
■ Treadwear
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a speci-
fied government test course.
For example, a tire graded 150 would wear one and a half (1 - 1/2)
times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual condi-
tions of their use. Performance may differ significantly from the norm
due to variations in driving habits, service practices and differences
in road characteristics and climate.
■ Traction AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B and C,
and they represent the tire’s ability to stop on wet pavement as
measured under controlled conditions on specified government test
surfaces of asphalt and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on braking
(straight ahead) traction tests and does not include cornering (turn-
ing) traction.

Vehicle specifications
■ Temperature A, B, C
The temperature grades are A (the highest), B, and C, representing
the tire’s resistance to the generation of heat and its ability to dissi-
pate heat when tested under controlled conditions on a specified
indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure.
Grade C corresponds to a level of performance which all passenger
car tires must meet under the Federal Motor Vehicle Safety Stan-
dard No. 109.
Grades B and A represent higher levels of performance on the labo-
ratory test wheel than the minimum required by law.
Warning: The temperature grades of a tire assume that it is properly
inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either sepa-
rately or in combination, can cause heat buildup and possible tire
failure.

AVERTISSEMENT
■ Précautions avec les coussins gonflables SRS
Respectez les précautions suivantes concernant les coussins gonflables
SRS.
À défaut, des blessures graves, voire mortelles, pourraient s’ensuivre.
● Le conducteur et tous les passagers à bord du véhicule doivent porter leur
ceinture de sécurité correctement.
Les coussins gonflables SRS sont des dispositifs de protection complé-
mentaires aux ceintures de sécurité.
● Le coussin gonflable SRS conducteur se déploie avec une puissance con-
sidérable et peut occasionner des blessures graves, voire mortelles, nota-
mment lorsque le conducteur se trouve très près du coussin gonflable.
L’autorité fédérale chargée de la sécurité routière aux États-Unis, la
NHTSA (National Highway Traffic Safety Administration) conseille:
Sachant que la zone de danger pour le coussin gonflable conducteur se
trouve dans les premiers 2 à 3 in. (50 à 75 mm) du déploiement, placez-
vous à 10 in. (250 mm) du coussin gonflable conducteur pour garantir
une marge de sécurité suffisante. Cette distance est à mesurer entre le
moyeu du volant de direction et le sternum. Si vous êtes assis à moins de
10 in. (250 mm), vous pouvez changer votre position de conduite de plu-
sieurs façons:
• Reculez votre siège le plus possible, tout en continuant à pouvoir
atteindre confortablement les pédales.
• Inclinez légèrement le dossier du siège.
Bien que la conception des véhicules varie, de nombreux conducteurs
peuvent atteindre la distance de 10 in. (250 mm), même avec le siège
du conducteur tout en avant, simplement en inclinant légèrement le
dossier du siège. Si vous avez des difficultés à voir la route après avoir
incliné votre siège, utilisez un coussin ferme et antidérapant pour vous
rehausser ou, si votre véhicule est équipé du réglage en hauteur du
siège, remontez-le.
• Si votre volant de direction est réglable, inclinez-le vers le bas. Cela
vous permet d’orienter le coussin gonflable vers votre buste plutôt que
vers la tête et le cou.
Le siège doit être réglé selon les recommandations de la NHTSA ci-des-
sus, tout en conservant le contrôle des pédales et du volant, et la vue des
commandes au tableau de bord.
504
MIRAI_OM_USA_OM62054U(18MY)_O
M62048U(19MY)
AVERTISSEMENT
■ Précautions avec les coussins gonflables SRS
● Le coussin gonflable SRS passager avant se déploie également avec une
puissance 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 peut infliger des blessures graves,
voire mortelles, aux nourrissons et aux enfants mal assis et/ou mal
attachés. Installez dans un siège de sécurité enfant les enfants trop jeunes
pour pouvoir utiliser la ceinture de sécurité. Toyota recommande vivement
que tous les nourrissons et enfants soient installés dans les sièges arrière
du véhicule et convenablement attachés. Les sièges arrière sont plus sûrs
pour les nourrissons et les enfants que le siège passager avant.
● N’installez jamais un siège de sécurité enfant type dos à la route sur le
siège passager avant, même si le témoin indicateur “AIR BAG OFF” est
allumé. En cas d’accident, la force exercée par le déploiement rapide du
coussin gonflable passager avant peut causer des blessures graves, voire
mortelles à un enfant, si le siège de sécurité enfant type dos à la route est
installé sur le siège passager avant.
● Si vous attachez une rallonge de cein-
ture de sécurité aux boucles des cein-
tures de sièges avant, mais pas au
pêne de la ceinture de sécurité propre-
ment dite, les coussins gonflables SRS
frontaux déterminent que le conducteur
et le passager avant portent leur cein-
ture de sécurité, alors même qu’elle
n’est pas attachée. Dans ce cas, les
coussins gonflables SRS frontaux ris-
quent de ne pas se déployer correcte-
ment en cas de collision, causant des
blessures graves, voire mortelles.
Veillez à porter la ceinture de sécurité
avec la rallonge de ceinture de sécurité.

sager avant ni assis sur les genoux du

■ Précautions avec les coussins gonflables SRS
● Ne pas suspendre aux crochets à vêtements un cintre nu ni aucun objet
dur ou tranchant. En cas de déploiement des coussins gonflables SRS
rideau, tous ces objets pourraient se transformer en projectiles et causer
des blessures graves, voire mortelles.
● Si une housse en vinyle recouvre la partie où le coussins gonflable SRS
de genoux se déploie, veillez à l’enlever.
● N’utilisez pour les sièges aucun accessoire venant recouvrir les parties où
se déploient les coussins gonflables SRS latéraux et le coussin gonflable
SRS d’assise de siège, car il risquerait de gêner le déploiement des cous-
sins gonflables SRS. De tels accessoires peuvent empêcher les coussins
gonflables SRS latéraux et d’assise de siège de s’activer correctement,
neutraliser le système ou provoquer le déploiement accidentel des couss-
ins gonflables SRS latéraux et d’assise de siège, provoquant ainsi des
blessures graves, voire mortelles.
● Ne rien fixer ou disposer sur la planche
de bord, la garniture centrale du moyeu
de volant de direction et la partie
inférieure du tableau de bord.
Lors du déploiement des coussins gon-
flables SRS conducteur, passager
avant et de genoux, tout objet risque de
se transformer en projectile.
● Ne rien fixer sur les parties telles que
les portes, la vitre de pare-brise, les vit-
res latérales, les montants avant et
arrière, les rails latéraux de toit et les
poignées de maintien.
(Sauf l’autocollant de limitation de
vitesse)

For owners
AVERTISSEMENT
■ Précautions avec les coussins gonflables SRS
● Évitez de faire subir des chocs ou des pressions excessives aux parties
renfermant les composants des coussins gonflables SRS.
En effet, cela pourrait entraîner un mauvais fonctionnement des coussins
gonflables SRS.
● Ne touchez aucun composant du système immédiatement après le
déclenchement (déploiement) des coussins gonflables SRS, car ils sont
alors encore très chauds.
● Si vous avez des difficultés à respirer après le déploiement des coussins
gonflables SRS, ouvrez une porte ou une vitre pour faire entrer de l’air
frais, ou bien descendez du véhicule si cela ne présente pas de danger.
Retirez tout résidu dès que possible afin d’éviter d’éventuelles irritations
de la peau.
● Si les parties renfermant les coussins gonflables SRS, telles que la garni-
ture centrale du volant de direction et les garnitures de montants avant et
arrière, apparaissent abîmées ou craquelées, faites-les remplacer par
votre concessionnaire Toyota.
● Ne rien poser sur le siège du passager avant, comme un coussin par
exemple. Cela a pour conséquence de répartir le poids du passager sur
toute la surface du siège, ce qui empêche le capteur de détecter normale-
ment le poids du passager. En conséquence, les coussins gonflables SRS
frontaux du passager avant peuvent ne pas se déployer en cas de colli-
sion.
