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-sensing mat, sensors, wiring, brack-
ets, and more. The function of the system in
the front passenger seat is checked by the
electronic control un it when the ignit ion is on .
The control unit mon itors the Advanced Air-
bag System and turns the airbag indicator
light on whe n a malfunction in the system
components is det ected. The function of the
airbag indicator light is described in greater
detai l be low. 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 f ront Advanced Airbag System
consists of the following:
- Crash sensors in the front of the veh icle that
measure veh icle acceleration/deceleration
to provide information to the Advanced Air-
bag System about the seve rity of the crash.
- An electron ic contro l unit, with integ rated
crash sensors for fron t and side impacts.
The contro l unit "dec ides " whether to fire
the front airbags based on the information
received from the crash sensors . The contro l
unit also "decides" whether the safety be lt
pretensioners shou ld be activated.
- An Advanced Airbag with gas generato r and
contro l valve for the driver inside the steer-
ing wheel hub.
- An Advanced Airbag with gas gene rator and
contro l valve inside the instrument panel for
the front passenger .
- 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 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 ~
page 161 .
- A sensor in each front seat registers the dis-
tance betwee n the respective seat a nd the
steer ing whee l or inst rument panel. The in-
formation registered is sent cont inuous ly to
t he ele ctron ic contro l unit to regula t e de-
ployment of the front Advanced Airbags .
- The PASSENGER AIR BAG OFF light comes
on and st ays on in the center of the instr u-
ment pa nel
~page 162, fig. 168 an d t ells
you when the front Advanced Airbag on the
passenger side has been turned off.
- A sensor below the safety be lt latch for the
front seat passenger to measure the tension
on t he safety be lt . The tension on the safety
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
~ page 153, Child restraints on the
front seat - some important things to
know.
- A sensor in the safety belt latch fo r the driv-
er and fo r the fro nt seat passenger that
senses whether that safety belt is latched or
not and transmi t s this information to t he
electronic control unit.
A WARNING
~
-
Damage to the front passenger seat can
prevent the front airbag from work ing
properly.
