Airb a g sys t e m
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the a irbag as poss ible, before insta lling
the forward-facing child restraint. The
backrest must be adjusted to an upr ight

Advanced Airbag System components
The fron t passenger sea t in your vehicle has a
lot of very important par t s of the Advanced
Airbag System in it. These parts include t he
weight -sensing mat, sensors, wiring, brack-
ets, and more. 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 turns the airbag indicator
light on when a ma lfunction in t he system
components is det ected. The func t ion of t he
a irbag ind icator 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 front 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 abou t the seve rity of the crash.
- An electron ic control unit, with integ rated
crash sensors for front and side impacts .
The cont rol unit "dec ides " whet her to fire
the front airbags based on t he information
received from the crash senso rs. The contro l
unit a lso "decides" whethe r the safety be lt
pretensioners should be activated .
- An Advanced Airbag with gas generator for
the driver inside the steering wheel hub.
- An Advanced Airbag with gas generato r in-
side the inst rument panel for the front pas-
senger.
- A we ight -sensing mat unde r t he upho lst ery
pa dding 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 .

light in t he instrument cluster
