■There is a malfunction in the system
*1: The system judges a person of adult size as an adult. When a smaller
adult sits in the front passenger seat, the system may recognize him/her
as a child depending on his/her physique and posture.
*2: In the event the front passenger is wearing a seat belt.
*3: In the event the front passenger does not wear a seat belt.
*4: When a larger child who has outgrown a child restraint system sits in the
front passenger seat, the system may recognize him/her as an adult
depending on his/her physique or posture.
*5: For the child’s safety, install the child restraint system to a rear seat.
When it is unavoidable, a child restraint system can be installed on the
front passenger seat. A rear-facing child restraint system should be
installed when “OFF” of the “PASSENGER AIR BAG” indicator is illumi-
nated. ( P. 6 7 )
*6: In case the indicator light is not illuminated, consult this manual on how to
install the child restraint system properly. ( P. 67)
*7: In the event of a side collision.
*8: In the event of a frontal collision.

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 “OFF” of the “PASSENGER AIR BAG” indicator to
be illuminated, which indicates that the SRS airbags for the front passen-
ger will not activate 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 pos-
sible 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, “ON” of the “PASSENGER AIR
BAG” indicator is illuminated. If “OFF ” of the “PASSENGER AIR BAG” indi-
cator 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 “OFF” of the
“PASSENGER AIR BAG” indicator still re mains 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. 6 7 )
● 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 any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer 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.
● When it is unavoidable to install a rear-facing child restraint system on the
front passenger seat, do not release the seat belt while the vehicle is mov-
ing. Doing so may cause the airbag system to be on.

WARNING
■ When installing a child restraint system
For safety reasons, always install the child restraint system in a rear seat. In
the event that the rear seat cannot be used, the front seat can be used as
long as the airbag manual on-off system is set to “OFF”.
If the airbag manual on-off system is left on, the strong impact of the airbag
deployment (inflation) may cause serious injury or even death.
■ When a child restraint system is not installed on the front passenger
seat
Ensure that the airbag manual on-off system is set to “ON”.
If it is left off, the airbag may not deploy in the event of an accident, which
may result in serious injury or even death.

Before installing a child restraint system in the vehicle, there are
precautions that need to be observed, different types of child
restraint systems, as well as installation methods, etc., written in
this manual.
● Use a child restraint system when riding with a small child that
cannot properly use a seat belt. For the child’s safety, install the
child restraint system to a rear seat. Be sure to follow the installa-
tion method that is in the operation manual enclosed with the
restraint system.
● The use of a Toyota genuine child restraint system is recom-
mended, as it is safer to use in this vehicle. Toyota genuine child
restraint systems are made specifically for Toyota vehicles. They
can be purchased at a Toyota dealer.

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.
■ 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. 74) 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.

WARNING
■When using a child restraint system
Observe the following precautions.
Failure to do so may result in death or serious injury.
● Vehicles with front passenger occupant classification system: Never use a
rear-facing child restraint system on the front passenger seat when “ON”
of the “PASSENGER AIR BAG” indicator is illuminated. ( P. 59)
The force of the rapid inflation of the front passenger airbag can cause
death or serious injury to children in the event of an accident.
● Vehicles without front passenger
occupant classification system or airbag
manual on-off switch: Never use a rear-
facing child restraint system on the front
passenger seat.
The force of the rapid inflation of the
front passenger airbag can cause death
or serious injury to children in the event
of an accident.
● Vehicles with airbag manual on-off
switch: Never use a rear-facing child
restraint system on the front passenger
seat when the airbag manual on-off
switch is on. ( P. 64)
The force of the rapid inflation of the
front passenger airbag can cause death
or serious injury to children in the event
of an accident.
● There is a label(s) on the passenger
side sun visor, indicating it is forbidden
to attach a rear-facing child restraint
system to the front passenger seat.
Details of the label(s) are shown in the
illustration below.

WARNING
■When using a child restraint system
● When a junior 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.
● Use child restraint system suitable to the age and size of the child and
install it to the rear seat.
● Only put a forward-facing child restraint
system on the front seat when unavoid-
able. When installing a forward-facing
child restraint on the front passenger
seat, move the seat as far back as pos-
sible. Failing to do so may result in
death or serious injury if the airbags
deploy (inflate).
● Vehicles with SRS side and curtain
shield airbags: Do not allow the child to
lean his/her head or any part of his/her
body against the door or the area of the
seat, front or rear pi llars, or roof side
rails from which the SRS side airbags or
SRS curtain shield airbags deploy even
if the child is seated in the child restraint
system. It is dangerous if the SRS side
airbags and curtain shield airbags
inflate, and the impact could cause
death or serious injury to the child.
● Double-cab models: If the driver’s seat
interferes with the child restraint system
and prevents it from being attached cor-
rectly, attach the child restraint system
to the right-hand rear seat (left-hand
drive vehicles) or the left-hand rear seat
(right-hand drive vehicles). ( P. 9 0 )
