1-7. Safety information
Front passenger occupant classification system
Your vehicle is equipped with a front passenger occupant classifica-
tion system. Using the sensors installed under the seat cover, the
system detects the conditions of the front passenger seat and acti-
vates or deactivates the frontal airbag for front passenger seat. The
occupant classification system m ay not inflate the front passenger’s
SRS frontal airbag even when the driver’s SRS frontal airbag
deploys. This is not a malfuncti on. If the seat belt buckle switch and/
or front passenger’s occupant classification system have failed , the
SRS warning light will illuminate. Have the system inspected by your
Toyota dealer immediately if the SRS warning light illuminates.
If your vehicle has sustained im pact, this may affect the proper func-
tion of the Toyota advanced frontal airbag system. Immediately con-
tact your Toyota dealer and have your vehicle inspected. Do not use
the front passenger seat while drivi ng to your Toyota dealer.

WARNING
■
Front passenger occupant classification system precautions
Observe the following precautions regarding front passenger occ upant clas-
sification system.
Failure to do so may cause the occupant classification system t o not function
correctly, resulting in death or serious injury.
● Wear the seat belt properly.
● Do not apply excessive force to the seat.
● Do not put sharp object(s) on the seat or pierce the seat uphol stery.
● Do not put objects under the front passenger seat.
● Do not use a seat accessory, such as a cushion or seat cover, t hat covers
the seat cushion surface.
● Do not spill liquid on the front passenger seat. If liquid is spilled, wipe it off
immediately and dry the seat. If the airbag warning light illum inates, dry
the seat until the warning light turns off. If the airbag warni ng light stays on
even when the seat has dried, do not allow anyone to sit on the front pas-
senger seat and have the system checked by your Toyota dealer. If the air-
bag warning light does not illuminate, check that the airbag ON /OFF
indicator light works properly. If the indicator light does not work properly,
do not allow anyone to sit in the front passenger’s seat and ha ve the sys-
tem inspected by your Toyota dealer.
● Do not remove or disassemble the front passenger seat. Also, do not
replace or modify the seat upholstery or foam inside the seat.
● Do not install any accessory (such as an audio amplifier) other than a gen-

WARNING
■Front passenger occupant classification system precautions
●Never install a rearward facing child seat in the front passeng er’s seat
even if the front passenger’s SRS frontal airbag is deactivated . Be sure to
install it in the rear seat in a correct manner. Also, it is strongly recom-
mended that any forward facing child seat or booster seat be in stalled in
the rear seat, and that even children who have outgrown a child restraint
system be also seated in the rear seat. This is because childre n sitting in
the front passenger’s seat may be killed or severely injured should the
front passenger’s SRS frontal airbag deploy. Toyota believes th at the rear
seats are the safest place for children
● If luggage or electronic devices are placed on the front passen ger seat,
the OFF indicator may turn off and the ON indicator may illumin ate. If this
occurs, the front passenger’s airbag may deploy during a collision. If this is
not desirable, remove the luggage or electronic devices from th e front pas-
senger seat.
● Modifications for persons with disabilities that may affect the front passen-
ger occupant classification system. (U.S. only) Removing, repla cing or
modifying any parts of the front seats, seat belts, front bumpe r, front side
frame, instrument panel, combination meter, steering wheel, ste ering col-
umn, tires, suspension or floor panel can affect the operation of the Toyota
front passenger occupant classification system.

Child restraint systems
Points to rememberStudies have shown that installin g a child restraint on a rear seat is
much safer than installing one to the front passenger seat.
● Choose a child restraint system that 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. 141)
Types of child restraints
Child restraint systems are classified into the following 3 typ es
according to the age an d size of the child.
Rear facing  Infant seat/convertible seat
A child restraint system for a sma ll child or baby must itself be prop-
erly restrained on the seat with the LATCH anchors or the 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.
