166 Airbag sys te m
removing, servicing or repairing a part in an
area of the vehicle can damage a part of an
a ir bag system and prevent that system from
working properly in a co llision.
There are some important things you have to know to make sure that the effectiveness of
the system will not be impa ired and that dis­
carded components do not cause injury or pol­ lute the env ironment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an airbag from deploy ing when needed or deploying
an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel horn pad or airbag cover
or the instrument pane l or modify them
in any way.
- Never attach any objects such as cup
holders or telephone mountings to the
surfaces covering the airbag units.
- For deaning the horn pad or instrument
pane l, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners cou ld damage the airbag cover
or change the stiffness or strength of the
material so that the airbag cannot de­
ploy and protect properly.
- Never repa ir, adjust, or change any parts
of the airbag system .
- All work on the steering wheel, instru­
ment pane l, front seats or electrical sys­
tem (including 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
authorized Audi dealer or qualified work­ shop.
- Never modify the front bumper or parts
of the veh icle body.
- Always make su re that the side airbag
can inflate without interference: -
Never install seat covers or rep lace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the orig inal seat covers or
to the seam in the area of the side air­
bag module must a lways be repaired
immediately by an author ized Audi
dealer.
- The airbag system can be activated only
once. After an airbag has inflated, it
must be replaced by an authorized Aud i
dealer or qualified technician who has
the technical information, training and
specia l equipment necessary .
- The airbag system can be deployed only
once. After an airbag has been deployed,
it must be replaced with new replace­
ment parts designed and approved espe­
cially for your Audi model version. Re­
placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only. Make sure that any airbag serv ice action
is entered in your Audi Warranty
& Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD.
- For safety reasons in severe accidents,
the alternator and starter are separated
from the vehicle battery with a pyrotech­
nic circuit interrupter.
- Work on the pyrotechnic c ircuit inter­
rupter must only be performed by a
qualified dea ler -risk of an accident!
- If the vehicle or the circuit interrupter
