There is a malfunction in the system
*1: The system judges a person of adult size as an adult. When a s
maller
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 ad ult
depending on his/her physique or posture.
*5: Never install a rear-facing child restraint system on the front passenger seat. A forward-facing child restraint system should only be installed on
the front passenger seat when it is unavoidable. ( P. 58)
*6: In case the indicator light is not illuminated, consult this manual on how
to install the child restraint system properly. ( P. 62)
*7: In the event of a side collision.
*8: In the event of a frontal collision or 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 le ft 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 “AI R BAG OFF”
indicator light is illuminated, disconnect the extender tongue from the seat
belt buckle, and reconnect the seat belt. Reconnect the seat be lt extender
after making sure the “AIR BAG ON” indicator light is illuminat ed. If you
use the seat belt extender while the “AIR BAG OFF” indicator li ght 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 equipm ent (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 passeng er 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 touc hes a rear
seat. This may cause the “AIR BAG OFF” indicator light to be il luminated,
which indicates that the SRS airbags for the front passenger wi ll 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 lesse n 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” indicat or still
remains illuminated, either ask the passenger to move to the re ar seat, or
if that is not possible, move the front passenger seat fully re arward.
● When it is unavoidable to install a forward-facing child restra int system on
the front passenger seat, install the child restraint system on the front pas-
senger seat in the proper order. ( P. 62)
● Do not modify or remove the front seats.
● Do not kick the front passenger seat or subject it to severe im pact. Other-
wise, the SRS warning light may come on to indicate a malfuncti on of the
front passenger occupant classification system. In this case, contact your
Toyota dealer immediately.
● Child restraint systems installed on the second 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 wit h the shift lever, wiper lever, etc.
● Use the rear door child-protector lock or the window lock switc h to
avoid children opening the door while driving or operating the
power window accidentally.
● 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 app ropriate 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 p laying 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.

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

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

vertible seatForward facing  Convertible
seat

WARNING
■Child restraint precautions
● For effective protection in automobile accidents and sudden sto ps, a child
must be properly restrained, using a seat belt or child restrai nt system
depending on the age and size of the child. 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.
● Toyota strongly urges the use of a proper child restraint syste m that con-
forms to the size of the child, installed on the rear seat. According to acci-
dent statistics, the child is safer when properly restrained in the rear seat
than in the front seat.
● Never install a rear-facing child restraint system on the front passenger
seat even if the “AIR BAG OFF” i ndicator light is illuminated.
In the event of an accident, the force of the rapid inflation o f the front pas-
senger airbag can cause death or serious injury to the child if the rear-fac-
ing child restraint system is installed on the front passenger seat.
● A forward-facing child restraint system may be installed on the front pas-
senger seat only when it is unavoidable. A child restraint system that
requires a top tether strap should not be used in the front passenger seat
since there is no top tether strap anchor for the front passenger seat.
Adjust the seatback as upright as possible and always move the seat as
far back as possible even if the “AIR BAG OFF” indicator light is illumi-
nated, because the front passenger airbag could inflate with considerable
speed and force. Otherwise, the child may be killed or seriously injured.
● Do not use the seat belt extender when installing a child restr aint system
on the front or rear passenger seat. If installing a child rest raint system
with the seat belt extender connected to the seat belt, the seat belt will not
securely hold the child restraint system, which could cause dea th or seri-
ous injury to the child or other passengers in the event of an accident.
