*1: The system judges a person of adult size as an adult. When asmaller adult sits in the front passenger 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 passenger does not wear a seat belt.
*3: When a larger child who has outgrown a child restraint systemsits in the front passenger seat, the system may recognize him/
her as an adult depending on hi s/her physique or posture.
*4: Never install a rear-facing child restraint system on the front pas-
senger seat. A forward-facing ch ild restraint system should only
be installed on the front passenger seat when it is unavoidable.
(  P.190)
*5: In case the indicator light is not illuminated, consult this manual
on how to install the child restraint system properly. ( P.194)

Front passenger occupant cl assification 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, 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 SRS airbags for the passenger will 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 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.

CAUTION
■Front passenger occupant cl assification 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 passenger will not deploy 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 vehi-
cle is moving. Reclining the seatback excessively may lessen the effec-
tiveness 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 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.194)
● 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 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 on 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.194)
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 U.S.A. and Canada now require the use of
child restraint systems.

190 1-7. Safety information

■
Selecting an appropriat e 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. 128)
CAUTION
■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 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.
Adjust the seatback as uprights 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.

192 1-7. Safety information
SIENNA_OM_OM45472U_(U)
CAUTION
■Child restraint precautions
● 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 an accident.
● Do not allow the child to lean his/her head or any part of his/her body
against the side door or the area of the seat, front and side pillars or roof
side rail from which the SRS side airbags or 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.
● 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.
