Before driving
Your vehicle is equipped with
ADVANCED AIRBAGS designed based
on US motor vehicle safety standards (FMVSS208). The airbag sys-
tem controls airbag deployment po wer for the driver and front pas-
senger. The driver airbag system consists of the driver seat’s position
sensor etc. The front passenger’s airbag system consists of the front
passenger occupant classification sensor etc.
The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag sensor assembly. The
airbag sensor assembly consists of a safing sensor and an airbag
sensor.
In certain types of severe frontal or side impacts, the SRS airbag sys-
tem triggers the airbag inflators. A chemical reaction in the inflators
quickly fills the airbags with non-toxic gas to help rest rain the motion
of the occupants.

smaller adult sits in the front pa ssenger seat, the system may rec-
ognize him/her as a child dependi ng on his/her physique and pos-
ture.
*2:In the event the front passenge r does not wear a seat belt.
*3: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 adult depending on his/her physique or posture.

Front passenger occupant cl assification system precautions
l 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 passen-
ger 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 remain illumi-
nated, either ask the passenger to move to the rear seat, or if that is not
possible, move the front passenger seat fully rearward.
l 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. 92)
l Do not modify or remove the front seats.
l 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.
