Advanced Airbag System components
The front passenger seat in your vehicle has a
lo t 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
detail below. Because the front passenger
seat contains important 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 control unit "decides" whether to fire
the front airbags based on the information
r eceived from the crash sensors. The control
Airbag system 115
unit also "decides" whether the safety belt
pretensioners should be activated.
- An Advanced Airbag with gas generator for
the driver inside the steering wheel hub.
- An Advanced Airbag with gas generator in­
side the instrument panel for the front pas­
senger.
- A weight-sensing mat under the upholstery
padding of the front passenger seat cushion
that measures the total weight on the seat.
The inform ation registered is sent continu­
ously to the electronic control unit to regu­
late deployment of the front Advanced Air­
bag on the passenger side.
- An airbag monitoring system and indicator
light in the instrument cluster
c:;. page 119.
-The PASSENGER AIR BAG OFF light comes
on and stays on in the center of the instru­
ment panel
c:;. page 119, fig. 107 and tells
you when the front Advanced Airbag on the
passenger side has been turned off.
- A sensor below the safety belt latch for the
front seat passenger to measure the tension
on the safety belt. The tension on the safety
belt and the weight registered 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
c:;. page 110, 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 control unit .
.&_ WARNING
Damage to the front passenger seat can
prevent the front airbag from working
properly.
- Improper repair or disassembly of the
front passenger and driver seat will pre­
vent the Advanced Airbag System from
functioning properly.
- Repairs to the front passenger seat must
be performed by qualified and properly
-
trained workshop personnel. 111>
