WARNING
■SRS airbag precautions
● The SRS front passenger airbag also deploys with considerable force, and
can cause death or serious injury especially if the front passenger is very
close to the airbag. The front passenger seat should be as far from the air-
bag as possible with the seatback adjusted, so the front passenger sits
upright.
● Improperly seated and/or restrained infants and children can be killed or
seriously injured by a deploying airbag. An infant or child who is too small
to use a seat belt should be properly secured using a child restraint sys-
tem. Toyota strongly recommends that all infants and children be placed in
the rear seats of the vehicle and proper ly restrained. The rear seats are
safer for infants and children than the front passenger seat. ( P. 52)
●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.
● Vehicles without SRS curtain shield air-
bags: Do not lean against the front door.
● Vehicles with SRS curtain shield air-
bags: Do not lean against the door, the
roof side rail or the front, side and rear
pillars.

WARNING
■SRS airbag precautions
● Do not use seat accessories which cover the parts where the SRS side
airbags inflate as they may interfere with inflation of the airbags. Such
accessories may prevent the side airbags from activating correctly, disable
the system or cause the side airbags to inflate accidentally, resulting in
death or serious injury.
● Do not strike or apply significant levels of force to the area of the SRS air-
bag components.
Doing so can cause the SRS airbags to malfunction.
● Do not allow anyone to kneel on the
passenger seat toward the door or put
their head or hands outside the vehicle.
● Do not attach anything to or lean any-
thing against areas such as the dash-
board, steering wheel pad.
These items can become projectiles
when the SRS driver and front passen-
ger airbags deploy.
● Vehicles without SRS curtain shield air-
bags: Do not attach anything to areas
such as a door, windshield and side
window.
● Vehicles with SRS curtain shield air-
bags: Do not attach anything to areas
such as a door, windshield, side win-
dow, front or rear pillar and roof side
rail. (Except for the speed limit label
 P. 465)

■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.
● Vehicles without SRS curtain shield airbags: Parts of the airbag module
(steering wheel hub, airbag cover and inflator) as well as the front seats may
be hot for several minutes. The airbag itself may also be hot.
● Vehicles with SRS curtain shield airbags: Parts of the airbag module (steer-
ing 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.
■ 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
20 - 30 km/h [12 - 18 mph] 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.

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

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

●Prioritize and observe the warnings, as well as the laws and regula-
tions for child restraint systems.
● Use a child restraint system until the child becomes large enough to
properly wear the vehicle’s seat belt.
● Choose a child restraint system appropriate to the age and size of
the child.
● Note that not all child restraint systems can fit in all vehicles.
Before using or purchasing a child restraint system, check the com-
patibility of the child restraint system with seat positions. ( P. 5 9 )
Points to remember
WARNING
■When a child is riding
Observe the following precautions.
Failure to do so may result in death or serious injury.
● For effective protection in automobile accidents and sudden stops, a child
must be properly restrained, using a seat belt or child restraint system
which is correctly installed. For inst allation details, refer to the operation
manual enclosed with the child restraint system. General installation
instruction is provided in this manual.
● Toyota strongly urges the use of a proper child restraint system that con-
forms to the weight and size of the child, installed on the rear seat. Accord-
ing to accident statistics, the child is safer when properly restrained in the
rear seat than in the front seat.
● Holding a child in your or someone else’s arms is not a substitute for a
child restraint system. In an accident, the child can be crushed against the
windshield or between the holder and the interior of the vehicle.

WARNING
■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.
● Depending on the child restraint system, installation may be difficult or
impossible. In those cases, check whether the child restraint system is
suitable for installment in the vehicle. ( P. 59) Be sure to install and
observe the usage rules after carefully reading the child restraint system
fixing method in this manual, as well as the operation manual enclosed
with the child restraint system.
● Keep the child restraint system properly secured on the seat even if it is
not in use. Do not store the child restraint system unsecured in the pas-
senger compartment.
● If it is necessary to detach the child restraint system, remove it from the
vehicle or store it securely in the luggage compartment.

■When installing a child restraint system to a front passenger
seat
For the safety of a child, install a child restraint system to a rear
seat. When installing a child restraint system to a front passenger
seat is unavoidable, adjust the seat as follows and install the child
restraint system.
● Move the front seat fully rear-
ward.
● Adjust the seatback angle to
the most upright position.
When installing a forward-
facing child seat, if there is a
gap between the child seat
and the seatback, adjust the
seatback angle until good
contact is achieved.
● Not suitable for child restraint
systems with support leg.
