Advanced Airbag System components
The fron t passenger sea t in your vehicle h as a
lot of very important par ts 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 u nit when the ignit ion is on.
The control unit mon itors the Advanced Air­
bag System and turns the airbag indicator
l ight on when a ma lfunction in t he system
components is detected. The func tion of the
a ir bag ind icator light is described in greater
detai l be low . Because the fro nt passenger
seat contains important parts of the Ad­
vanced A irbag System, you m ust 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 Airb ag System
consists of the following:
- Crash sensors in the front of the veh icle that
measure veh icle acceleration/decele ration
to provide information to the Advanced Air­
bag System abou t the seve rity of the crash.
- An e lectron ic co ntrol unit, with integ rated
c rash sensors for front and side impacts .
T he cont rol unit "dec ides " w het her to fire
the front airbags based on the 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 Ai rbag w ith gas generator for
the driver inside the steering w heel hub.

Monitoring the
Advanced Airbag
System
I Airbag monitoring indicator light
Two separate indicators monitor the function
of the Advanced Airbag System: the airbag
monitoring indicator light and the
PASSEN­
GER AIR BAG
OFF light.
The Advanced Airbag System (includ ing the
electronic control unit, sensor circuits and sys­
tem wiring) is monitored continuously to
make sure that it is functioning properly
whenever the ignit ion is on. Each time you
turn on the ignition, the airbag monitoring in­
dicator light
I will come on for a few seconds
(self diagnostics) .
The system must be inspected when the
indicator light
I :
- does not come on when the ignit ion is
switched on,
- does not go out a few seconds after you
have switched on the ignition, or
- comes on while driving.
If an airbag system malfunction is detected,
the indicator light will first start flashing to
catch the driver's attention and then stay on
continuously to serve as a constant reminder
to have the system inspected immediately.
If a malfunction occurs that turns the front
a ir bag on the passenger side off, the
PASSEN­
GER AIR BAG
OFF light will come on and stay
on whenever the ignition is on.
_& WARNING
An airbag system that is not funct ioning
properly cannot provide supplemental pro­
tection in a frontal crash.
-If the airbag indicator light comes on, it
means that there may be something
wrong with the Advanced Airbag System.
It is possible that the airbag will inflate
when it is not supposed to, or will not in­
flate when it should.
-
- Have the airbag system inspected imme­
diately by your authorized Audi dea ler.
