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 power
for the driver and front pas-
senger. The driver airbag system consists of the driver seat’s position
se
nsor 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 imp
acts, the SRS airbag sys-
tem triggers the airbag inflators. A chemical rea
ction in the inflators
quickly fills the airbags with non-toxic gas to help restrain the motion
of the occupants.

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

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. ( →
