- If the PASSENGER AIR BAG OFF light does

(D Tips
If the capacitive passenge r detection system
determines that the front passenger seat is

AIR BAG OFF light will stay on.
Repair , care and disposal of the airbags
Parts of the a irbag system are installed at many
d ifferent places on your Aud i. Install ing , remov­
ing, servic ing or repa iring a part in an area of the
ve hicle can damage a pa rt of an airbag system
and p revent that system from working properly
in a co llision .
There are some important th ings you have to
know to make sure that the effect iveness of the
system w ill not be impaired and th at discarded
components do not cause injury or pollute the
environment .
A WARNING
Improper care, servicing and repair proce ­
dures can increase the r isk of personal injury
and death by preventing an airbag from de­
ploying when needed or dep loying an airbag
unexpectedly:
284
-
- 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 ho lders
or telephone mountings to the surfaces cov­
ering the a irbag un its .
- For cleaning the horn pad or instrument panel, use only a soft, dry cloth or one mois­
tened w it h plai n water . Solvents or cleaners
could damage the airbag cover or change
the st iffness or strength of the material so
that the ai rbag cannot deploy and p rotect
p roperly.
- Never repair, ad just, o r change any parts of
the airbag system.
- All work on the steer ing wheel, inst rument
pa nel, front seats o r electr ica l system ( in­
cl uding the insta llation of a udio eq uipment,
cell ular te lephones and CB radios, etc.)
m ust be performed by a qualified techn ician
who has the training and specia l equipment
necessary.
- For any work on the airbag system, we
strong ly recommend that you see yo ur a u­
thorized A udi dealer or qualified workshop .
- Never modify the front b umper or parts of
the vehicle body.
-Always make sure that the side airbag can inf late wit hout interference:
- Never install seat covers or replacement upholstery ove r the front seatbacks that
have not bee n specifica lly approved by
A udi .
- Never use additional seat c ushi ons that
cover the areas where the side airbags in­
flate.
- Damage to the orig inal seat cove rs or to
t h e seam in the area of the s ide a irbag
module mus t always be repai red immedi ­
ate ly by an authorized Aud i dealer.
- The airba g sys tem can deploy o nly on ce. Af ­
t er an airbag has been dep loyed, i t m ust be
replaced with new replaceme nt parts de ­
signed and approved especia lly for your
Aud i mode l version . Rep lacement of com­
plete airbag systems or airbag components
must be performed by qua lified workshops
only . Make sure t hat any airbag service

Checking and Filling
~ After the fuel pump has switched off, wait five seconds before removing it to allow the rest of
the fuel to finish dripping into the fuel tank.
~ Turn the fue l cap clockwise until you hear it
lock.
~ Close the fuel filler door and then press on the
left side until it latches .
The correct fuel type for your vehicle can be
found on a label located on the inside of the fuel
filler door. For additional information on fuel,
see
Qpage 314 .
For the tank capacity in your vehicle, refer to the
Technical Data
Qpage 382.
To reduce the risk of fuel leaking out or vapors
escaping, make sure that the fuel tank is closed
correctly. Otherwise
thP ¢..iff indicator light will
turn on.
If the centra l locking system malfunctions, the
fuel filler door may emergency release
Qpage317.
A WARNING
An improper fueling procedure and improper
handling of fuel can lead to explosions, fires,
severe burns and other injuries.
-Do not smoke and keep away from open
flames.
-The ignition must be switched off when re­
fueling.
-Cell phones, radio devices and other radio
equipment should always be switched off
when refueling. Electromagnetic rays could cause sparks and start a fire.
-If you do not insert the fuel pump nozzle all
the way into the filler tube, then fuel can
leak out. Spilled fuel can ignite and start a
fire.
-Never get into the vehicle when refueling. If
there is an exceptional situation where the
vehicle must be entered, close the door and
touch a metal surface before touching the
fuel pump nozzle again. This will reduce the
risk of electrostatic discharge that can cause
flying sparks. Sparks can start a fire when
refueling.
316
A WARNING
We recommend that you do not transport any
fuel containers in the vehicle. Fuel could leak
out of the container and ignite, especially dur­
ing an accident. This can cause explosions,
fires and injuries.
-If you must transport fuel in a fuel contain­
er, please note the following:
-Always place a fuel container on the
ground before filling. Never fill the fuel
container with fuel while it is in or on the
vehicle. Electrostatic charge can occur
while refueling and the fuel vapors could
ignite .
-For fuel containers made of metal, the
fuel pump nozzle must always maintain
contact with the container to reduce the
risk of static charge.
-Insert the fuel pump nozzle as far as pos­
sible into the filler opening while refuel­
ing.
-Follow legal requirements when using,
storing and transporting fuel containers.
-Make sure that the fuel container meets
the industry standards, for example ANSI
or ASTM F852-86.
@ Note
-Remove fuel that has overflowed onto any
vehicle components immediately to reduce
the risk of damage to the vehicle.
-Never drive until the fuel tank is completely
empty. The irregular supply of fuel that re­
sults from that can cause engine misfires.
Uncombusted fuel will enter the exhaust
system and increase the risk of damage to
the catalytic converter.
@I For the sake of the environment
Do not overfill the fuel tank, otherwise fuel
can leak out when the vehicle is warming up.
© Tips
The fuel filler door on your vehicle does not lock if you lock the vehicle from the inside us-
ing the central locking switch.
