Advanced Airbag System components
The front passenger seat in your vehicle has a
lot of very important parts of the Advanced
Airbag System in it. These parts include the
weight-sens ing mat, sensors, wiring, brack-
ets, and more . The fu nction of the system in
the front passenger seat is checked by the
e lectronic control unit when the ignit ion is on.
The control unit mo nitors the Advanced Air-
bag Syst em a nd tu rns t he airbag indicator
light on when a ma lfunction in the system
components is detected . The function of the
airbag ind icator light is described in greater
detai l below. Because the front passenger
seat contains important parts of the Ad-
vanced Airbag System, you must take care to
prevent it from be ing damaged . Damage to
the seat may prevent the Advanced Airbag for
the front passenger seat from doing its job in
a crash .
The front Advanced Airbag System
consists of the following:
- Crash senso rs in the front of the veh icle that
measu re vehicle accelera t ion/de cele rati on
to provide info rmation to the Advanced Air-
bag System abo ut the severity of the crash .
- An elect ronic contro l unit, with integrated
crash sensors for front and side impacts .
The control un it "decides" whether to fire
the front a irbags based on the informat ion
received from the crash sensors. The contro l
un it also "decides" whether the safety belt
prete ns ioners shou ld be act ivated .
- An Advanced Airbag w ith gas generator for
the dr iver inside the stee ring wheel hub .
- An Advanced Airbag w ith gas generator in-
side the instrument panel for the front pas-
senge r.
- A we ight-sensing mat under the up ho lstery
padding of the front passenger seat cushion
that measures the total weight on the seat .
The informat io n registe red is sent continu-
ou sly to the elec t roni c con t rol unit to regu -
lat e d eployment of the front Advanced Air-
bag on the passenger side .

- A sensor below the safety be lt latch for the
front seat passenger to meas ure the tension

be lt and the weight registered by the
weight-sensing
mat he lp the control unit
"decide" whether the front airbag for the
front passenger seat should be turned off or
not
