Repair, care and disposal of the airbags
Parts of the a irbag system are installed at many
d ifferent p laces on your Aud i. Install ing, remov­
i n g, servic ing o r repa iring a part in an area of the
ve hicle can damage a pa rt of an airbag system
and prevent that system from working properly
in a co llision .
There are some important t hings yo u have to
know to make sure th at the effect iveness of the
system wi ll not be impaired and that dis carded
components do not cause injury or pollute the
environment .
A WARNING
Improper care, serv icing and repair proce­
dures can increase the r isk of personal injury
and death by preventing an airbag from de­
ploying when needed or deploying an airbag
unexpectedly:
-
-Never cover, obstruct, or change the steer­
i ng wheel horn pad or a irbag cover or the in­
strument pa ne l or mod ify them in any way.
-Never attach any objects such as cup holders
o r te lephone mount ings to the surfaces cov­
er ing the ai rbag units.
-For cleaning the horn pad or instrument
pane l, use on ly a soft, dry cloth or one mois­
tened with plain water. Solvents or cleaners cou ld damage the airbag cover or change
the stiffness or st rengt h of the materia l so
t h at the airbag cannot dep loy and protect
properly.
-Never repair, adjust, or change any parts of
the airbag system.
-All work on the stee ring wheel, i nstr ument
pane l, front seats or electrical system (in ­
cluding the installation of audio equipment,
ce llular telephones and CB rad ios, etc.)
must be performed by a qualified technician
240
who has the training and specia l equipment
necessary.
-F or any work on the airbag system, we
strong ly recommend that you see yo ur au­
thorized Audi dealer or qualified workshop.
-Never modify the front b umper or parts of
the vehicle body.
- Always make sure that the side airbag can
inflate w ithout interference:
-Never install seat covers or replaceme nt
upholstery ove r the front seatbacks that
have not bee n specific ally app roved by
A udi.
-Neve r use additional seat c ushi ons that
cover the areas where the side airbags in ­
flate.
-Damage to the orig inal seat cove rs o r to
t h e seam in the area of the s ide airb ag
module mus t always be repai red immedi ­
ate ly by an authorized Audi dealer.
-The airb ag sys tem can be act iv a ted only
once . A fter an airbag has in flated, it must
be replaced by an authorized Audi dealer or
qua lified tech nic ian who has the technical
information, train ing and spec ial equ ipment
necessary.
-The airbag system can be deployed only
once. After an airbag has been deployed, it
must be replaced with new rep lacement
parts des igned and approved espec ially for
your Aud i model version. Replacement of
comp lete airbag systems or airbag compo­
nents must be perfo rmed by qualified work­
shops only. M ake sure that any a irb ag se rv ­
ice act ion is entered in your Audi Warranty
& Maintenance booklet under AIRBAG RE ­
PLACEMENT RECORD.
-For safety reasons in severe accidents, the
a lter nator and starter a re separated from
the vehicle battery with a pyrotechnic circu it
interrupter.
-Wo rk on the pyrotechnic c ircuit inte rrupt­
e r must o nly be perfo rmed by a qua lified

A pp lies to: ve hicles w ith gasoline engines
The vehicle may on ly be driven with unleaded
gasoline, otherwise the catalyt ic converter will be
destroyed.
Never d rive until the tank is comp letely empty .
The irregular supp ly of f uel that results from that
can cause engine m isfires. Uncombusted fuel will
enter the exhaust system , w hich can cause over­
heating and damage to the catalyt ic converter .
A WARNING

be burned. Wait unt il no steam or coolant is
escaping.
- Keep children away from the eng ine com­
pa rtment.
- Never sp ill fluids on a hot engine. These flu­
ids (such as the anti-freezing agent con­
tained in the coolant) can ignite .
- Avoid short c ircuits in the electrical system.
- When working in the engine compa rtment,
remember that the radiator fan can switch
on even if the ignition is switched off, wh ich
increases the r isk of persona l injury.

- Do not remove the engine cove r under any
circumstances . T his increases the risk of
burns.
- If tests need to be perfo rmed with the en­
gine running, there is add itiona l danger due
to mov ing components (such as the r ibbed
be lt, alterna tor and rad iator fan) and from
the high-voltage ignition system.
- Do not unde r any circ ums tances activate the

_& WARNING
-The cooling system is under pressure. Do
not open the coolant expansion tank cap
when the engine is hot. This increases the
risk of burns .
- The coolant additive and the coolant can be dangerous to your health. For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
CD Note
Do not add coolant if the expansion tank is
empty. Air could enter the cooling system and
damage the engine. If this is the case, do not
continue driving. See an authorized Audi deal­

-
- If the brake fluid level is below the MIN
marking, it can impair the braking effect
and driving safety, which increase the risk of
an accident . Do not continue driving . See an
authorized Audi dealer or authorized Audi
Service Facility for assistance.
- If the brake fluid is old, bubbles may form
in the brake system during heavy braking.
This would impair braking performance and
driving safety, which increases the risk of an
