Airb a g sys t e m
the front passenger seat is checked by t he
e lectronic control unit when the ig nition is on .
The control unit mon itors 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
a irbag ind icator light is described in greater
deta il be low. Because the front passenger
seat conta ins impo rtant parts of t he Ad-
va nce d Airbag System, you m ust ta ke 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
consist s of th e following :
- Crash sensors in the front of the veh icle that
measure veh icle acceleration/dece leration
to provide information to the Advanced Air-
bag System about the severity of the crash.
- An electronic contro l unit, with integrated
crash sensors for front and side impacts.
The contro l unit "decides" whether to fire
the front airbags based on the information
received from the crash sensors. The contro l
unit a lso "dec ides" w hethe r t he safety be lt
pretensioners should be activated.
- An Advanced Airbag with gas generator for
