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 function of the system in
the front passenger seat is checked by the
electronic 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 indicator 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 celeration
to provide information 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 with gas generator and
cont rol valve for the driver ins ide the steer -
ing wheel hub .
- An Advanced Airbag with gas generator and
cont rol valve inside the inst rument panel for
the front passenger .
- A we ight-sensing mat under the up holstery
padding of the front passenge r seat cushion
that measures the total weight on the seat.
The info rmation reg iste red is sent continu-
ously to the elec tr onic control un it to regu-
lat e deployment of the front Advanced Air-
bag on the passenger side .
- An airbag monitor ing syst em and indicator
light in t he instr ument cluster ¢
