Airbag system


fore and aft adjustment range, as far away
from the airbag as possible. The backrest
must be adjusted to an upright position.
Make sure that the PASSENGER AIR BAG
OFF light comes on and stays on all the time
whenever the ignition is switched on.

ZA WARNING
— If the PASSENGER AIR BAG OFF light does
not go out when an adult is sitting on the
front passenger seat after taking the steps
described above, make sure the adult is
properly seated and restrained at one of the
rear seating positions.
— Have the airbag system inspected by your
Audi dealer before transporting anyone on
the front passenger seat.
@) Tips
If the capacitive passenger detection system
determines that the front passenger seat is
empty, the frontal airbag on the passenger
side will be turned off, and the PASSENGER
AIR BAG OFF light will stay on.
Repair, care and disposal of the airbags
Parts of the airbag system are installed at many
different places on your Audi. Installing, remov-
ing, servicing or repairing a part in an area of the
vehicle can damage a part of an airbag system
and prevent that system from working properly
in a collision.

There are some important things you have to
know to make sure that the effectiveness of the
system will not be impaired and that discarded
components do not cause injury or pollute the
environment.

ZA WARNING
Improper care, servicing and repair proce-
dures can increase the risk of personal injury
and death by preventing an airbag from de-
ploying when needed or deploying an airbag
unexpectedly:

268

— Never cover, obstruct, or change the steer-
ing wheel horn pad or airbag cover or the in-
strument panel or modify them in any way.
— Never attach any objects such as cup holders
or telephone mountings to the surfaces cov-
ering the airbag units.
— For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one mois-
tened with plain water. Solvents or cleaners
could damage the airbag cover or change
the stiffness or strength of the material so
that the airbag cannot deploy and protect
properly.
— Never repair, adjust, or change any parts of
the airbag system.
— All work on the steering wheel, instrument
panel, front seats or electrical system (in-
cluding the installation of audio equipment,
cellular telephones and CB radios, etc.)
must be performed by a qualified technician
who has the training and special equipment
necessary.
— For any work on the airbag system, we
strongly recommend that you see your au-
thorized Audi dealer or qualified workshop.
— Never modify the front bumper or parts of
the vehicle body.
— Always make sure that the side airbag can
inflate
without interference:
— Never install seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
Audi.
— Never use additional seat cushions that
cover the areas where the side airbags in-
flate.
— Damage to the original seat covers or to
the seam in the area of the side airbag
module must always be repaired immedi-
ately by an authorized Audi dealer.
— The airbag system can deploy only once. Af-
ter an airbag has been deployed, it must be
replaced with new replacement parts de-
signed and approved especially for your Audi
model version. Replacement of complete
airbag systems or airbag components must
be performed by qualified workshops only.
Make sure that any airbag service action is

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you.
It is becoming increasingly more and more diffi-
cult to replace vehicle light bulbs since in many
cases, other parts of the car must first be re-
moved before you are able to get to the bulb.
This applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment.
Sheet metal and bulb holders can have sharp
edges that can cause serious cuts, parts must be
correctly taken apart and then properly put back
together to help prevent breakage of parts and >
