Advanced Airbag System components
The fron t passenger seat in your vehi cle has a
l ot of very important par ts of the Advanced
Airbag System in it. These parts include t he
weight -sens ing mat, sensors, wiring, brack­
ets, and mo re. The function of the system in
the front passenger seat is checked by the e lectronic control un it when the ignit ion is on.
The control unit mon itors the Advanced Air­
bag System and tur ns the a irbag indicator
light on when a ma lfu nction in t he system
components is de tected. The func tion of the
a ir bag ind icator light is described in greater
detai l below . Because t he front passenge r
Airbag sys tem 119
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 do ing its job in
a crash.
The front Advanced Air bag System
consists of the following:
- Cras h sensors in the front of the vehicle that
measure vehicle acceleration/deceleration
to prov ide info rmat ion to the Adva nced Ai r­
bag System about the sev erity of the crash .
- An elect ronic control unit, with integrated
crash sensors fo r front and s ide impacts.
The control u nit "decides" whether to fi re
t he front a irbags based on t he informat io n
received from t he crash sensors. The con trol
unit also "decides" whe ther the sa fety belt
pretensioners sho uld be activated.
- An Adv anced A irbag w it h gas gene ra tor and
cont ro l valve fo r the d river inside the steer ­
ing wheel h ub.
- An Advance d Airbag w ith gas generator and
contro l valve inside the inst rument pane l for
the front passenger .
- A wei ght -sensing mat unde r the upho ls tery
padding of the front passenge r seat cushion
that measures the total weight on the seat .
The informat ion reg istered is sent continu­
ously to the electronic control unit to regu­
late deployment of the front Advanced Air­
bag on t he passenger side.
- An airbag monitoring system and ind icator
light in the instr ument cluster¢
page 123.
-A sensor in each front seat registers the dis­
tance between the respective seat and the
steer ing whee l or inst rument panel. The i n­
formation register ed is sent cont inuo usly to
t he ele ct ron ic cont ro l unit to regula te de­
ployment o f th e front Adva nced A irbags .
