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 pa ssenger seat, the system may rec-
ognize him/her as a child depending on his/her physique and pos-
ture.
*2: In the event the front passenge r does not wear a seat belt.
*3: When a large 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.
*4: Never install a rear-facing child restraint system on the front pas- senger seat. A forward-facing chil d restraint system should only
be installed on the front passenger seat when it is unavoidable.
(  P. 132)
*5: In case the indicator is not illumin ated, consult this manual as for
installing the child restraint system properly. ( P. 137)

CAUTION
■Front passenger occupant cl assification system precautions
Observe the following precautions regarding front passenger occupant clas-
sification system. 
Failure to do so may cause death or serious injury.
● Wear the seat belt properly.
● Make sure the front passenger’s seat belt tab 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, then 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 front passenger airbag on the front passenger side may not
activate correctly, which could cause death or serious injury in the event of
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 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.
● 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 passenger’s airbags will not deploy in the event of
a severe accident. If the seatback touches the rear seat, return the seat-
back 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.

Front passenger occupant cl assification system precautions
● If an adult sits in the front passenger seat, the “AIR BAG ON” indicator
light is illuminated. If the “AIR BAG OFF” indicator light 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 light still
remain 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 the forward-facing child restraint system
on the front passenger seat, install the child restraint system on the front
passenger seat in the proper order. ( P. 137)
● 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 on the
detection 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 or seat cover, that covers
the seat cushion surface.
● Do not modify or replace the upholstery of the front seat.

Child restraint systems
Points to rememberStudies have shown that installing a child restraint system on a rear
seat is much safer than installing one to the front passenger seat.
● Choose a child restraint system th at suits your vehicle and is
appropriate to the age and size of the child.
● For installation details, follow the instructions provided with the
child restraint system. 
General installation instructions are provided in this manual. 
(  P. 137)
Types of child restraints
Child restraint systems are classi fied into the following 3 types
according to the age and size of the child.
Rear facing  Infant seat/convertible seat
A child restraint system for a small ch ild or baby must itself be prop-
erly restrained on the seat with th e lap portion of the lap/shoulder
belt.
The laws of all 50 states of the U.S.A. and Canada now require the
use of child restraint systems.

■When installing the child restrain t system on the front passenger seat
■ Selecting an appropriat e child restraint system
● Use a child restraint system appropriate for the child until the child
becomes large enough to properly w ear the vehicle’s seat belt.
● If a child is too large for a child restraint system, sit the child on a rear
seat and use the vehicle’s seat belt. ( P. 85)
When you have to use a child restraint
system on the front passenger seat,
adjust the following:
●The seatback to the most upright
position
● The seat cushion to the fully rear-
ward position

Child restraint precautions
● For effective protection in automobile accidents and sudden stops, a child
must be properly restrained, using a seat belt or child restraint system
depending on the age and size of the child. Holding a child in your arms is
not a substitute for a child restraint system. In an accident, the child can be
crushed against the windshield, or between you and the vehicle’s interior.
● Toyota strongly urges the use of a proper child restraint system that con-
forms to the size of the child, installed on the rear seat. According to acci-
dent statistics, the child is safer when properly restrained in the rear seat
than in the front seat.
● Never install a rear-facing child restraint system on the front passenger
seat even if “AIR BAG OFF” indicator light is illuminated. In the event of an
accident, the force of the rapid inflation of the front passenger airbag can
cause death or serious injury to the child if the rear-facing child restraint
system is installed on the front passenger seat.
● A forward-facing child restraint system may be installed on the front pas-
senger seat only when it is unavoidable. A child restraint system that
requires a top tether strap should not be used in the front passenger seat
since there is no top tether strap anchor for the front passenger seat.
Adjust the seatback as upright as possible and always move the seat as
far back as possible even if “AIR BAG OFF” indicator light is illuminated,
because the front passenger airbag could inflate with considerable speed
and force. Failing to do so may cause death or serious injury to the child.
● Do not use the seat belt extender when installing a child restraint system
on the front or rear passenger seat. If installing a child restraint system
with the seat belt extender connected to the seat belt, the seat belt will not
securely hold the child restraint system, which could cause death or seri-
ous injury to the child or other passengers in the event of a sudden stop,
sudden swerve or accident.

CAUTION
■Child restraint precautions
● 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, center and rear pillars or
roof side rail from which the side airbags or curtain shield airbags deploy
even if the child is seated in the child restraint system. It is dangerous if
the side airbags and curtain shield airbags inflate, and the impact could
cause death or serious injury to the child.
● Make sure you have complied with all installation instructions provided by
the child restraint manufacturer and that the system is properly secured. If
it is not secured properly, it may cause death or serious injury to the child
in the event of a sudden stop, sudden swerve or an accident.
■ Child restraint lock function belt precaution
Do not allow children to play with the child restraint lock function belt. If the
belt becomes twisted around a child’s neck, it will not be possible to pull the
belt out leading to choking or other serious injuries that could result in death. 
If this occurs and the buckle cannot be unfastened, scissors should be used
to cut the belt.
■ When the child restrain t system is not in use
● Keep the child restraint system properly secured on the seat even if it is
not in use. Do not store the restraint unsecured in the passenger compart-
ment.
● If it is necessary to detach the child restraint system, remove it from the
vehicle or store it securely in the luggage compartment. This will prevent it
from injuring passengers in the event of a sudden stop, sudden swerve or
an accident.
