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 ignition is on.
The control unit monitors the Advanced Air-
bag System and turns the airbag indicator
light on when a malfunction in the system
components is detected. The function of the
airbag indicator light is described in greater
deta il below. Because the front passenger
seat contains impo rtant parts of the Ad-
vanced Airbag System, you must take care to
prevent it from being 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 sensors in the front of the vehicle that
measure vehicle acceleration/deceleration
to provide information to the Advanced Air-
bag System about the severity of the crash.
-An electronic control unit, with integrated
crash sensors for front and side impacts .
The cont rol unit "decides" whether to fire
the front airbags based on the information
received from the crash sensors. The control
unit also "dec ides" whet her the safety belt
pretensione rs should be activated.
- An Advanced Airbag with gas generator for
the driver inside the steer ing whee l hub.
- An Advanced Airbag with gas generator in-
side t he instr ument pane l for the front pas-
senger.

- A weight-sensing mat under the upho lstery
padding of the front passenger seat cushion
that measures the total weight on the seat .
The informat ion registered is sent continu-
ously to the electron ic control unit to regu-
late deployment of the front Advanced Air-
bag on the passenger side.

light in the instrument cluster

- The PASSENGER AIR BAG OFF light comes
on and stays on in the center of the instru-
ment panel
c:::> page 133, fig. 134 and tells
you when the front Advanced Airbag on the
passe nger side has been tu rned off.
- A senso r below the safety belt latch for the
front seat passenger to measure the tension
on the safety be lt. The ten sion on the safety
be lt and the weight regis tered by the
weight -sensing mat help the control unit
"decide" whether the front airbag for the
front passenger seat should be turned off or
not
¢ page 123, Child restraints on the
front seat - some important things to
know.
-A sensor in the safety belt latch for the driv-
er and for the front seat passenger that
senses whether that safety belt is latched or
not and transmits this information to the
electronic contro l un it .
A WARNING

prevent the front airbag from wor king
properly.
- Imp roper repai r or disassembly of the
front passenge r and driver seat will pre-
vent the Advanced Airbag System from
functioning properly.

be pe rformed by qualified and properly
trained workshop personne l.
