door or window to allow fresh air in, or leave the vehicle if it is safe to do
so. Wash off any residue as soon as possible to prevent skin irritation.

pad and front and rear pillar garnishes, are damaged or cracked, have
them replaced by your Toyota dealer.

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, side 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 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 except for putting them
in the tray.
● 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.

CAUTION
■
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 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. 140)
● 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
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.

1-7. Safety information
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 that suits your vehicle and appro-
priate 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. 140)
A child restraint system for a small child or baby must be properly
restrained on the seat with the 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.
