Repair, care and disposal of the airbags
P arts of the airbag system are installed at many different p laces on
you r Aud i. Insta ll ing, r emoving, servic ing or repa iring a pa rt in an
area of the vehicle can damage a part of an airbag system and
p revent that sys tem from working pr operly in a c ollisi on.
There are some important things you have to know to ma ke sure
t h at the effective ness of the system will not be impai red and that
discarded co mponents do not cause injury or po llute the env iro n­
ment .
& WARNING
Improper care , servicing and repair procedures can increase the
risk of personal injury and death by pre venting an airbag from
deploying when needed or deploying an airbag unexpectedly:
• Never cover , obstruct , or change the steering wheel horn pad
or airbag cover or the instrument panel or modify them in any way .
• Never attach any objects such as cupholders or telephone
mountings to the surfaces covering the airbag units .
• For cleaning the horn pad or instrument panel , use only a soft,
dry cloth or one moistened with plain water. Solvents or cleaner s
c ould damage the airbag cover or change the stiffness or strength
of the material so that the airbag cannot deploy and protect prop ­
erly .
• Never repair , adju st, or change any parts of the airbag sy stem .
• All work on the steering wheel , instrument panel , front seats or
electrical system (including the installation of audio equipment ,
cellular telephones and CB radios , etc .I 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 author ized Audi dealer or qual ified workshop .
• Never modify the front bumper or parts of the vehicle body .

& W ARNING (continued )
• Always make sure that the side airbag can inflate without inter­
ference :
- 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 inflate.
- Damage to the or iginal 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 be activated only once. After an airbag
has inf lated , it must be replaced by an authorized Audi dealer or
qualified technician who has the technical information , training
and special equipment necessary .
• The airbag system can be deployed only once . After an airbag
has been deployed, it must be replaced with new replacement
parts designed 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 entered in you r Audi

Side airbags
Description of side airbags
The airbag system can provide supplemental protection
to properly restrained occupants.
Fig. 207 Side airbag
location in the driver 's
seat
The side airbags are located in the sides of the front seat backrests
~ fig. 207 and the rear backrest * facing the doors. They are identi ­
fied by the word "AIRBAG" .
The side airbag system basically consists of :
• the electronic control module and external side impact sensors
• the two side airbags located in the sides of the front backrests
• two rear side airbags (as an ordered
option)
• the airbag warning light in the instrument cluster .
The airbag system is monitored electronically to make certain that
it is functioning properly at all times. Each time you turn on the igni ­
tion, the airbag system indicator light will come on for a few
seconds (self diagnostics).
The side airbag system supplements the safety belts and can help
to reduce the risk of injury to the driver's , front and rear*
passenger's upper torso on the side of the vehicle that is struck in a
side collision . The airbag deploys only in side impacts and only
when the vehicle acceleration registered by the control unit is high
~

enough. If this rate is be low the reference value programmed into
the control unit, the side airbags will not be triggered, even though
the car may be badly damaged as a result of the collision . It is not
possible to define an airbag triggering range that wi ll cover every
possible angle of impact, since the circumstances will vary consid­
erably between one collision and another . Important factors
include, for example, the nature (hard or soft) of the impacting
object, the angle of impact, vehicle speed, etc.~
page 230, "Impor ­
t ant safety instructions on the side a irbag syste m".
Aside from their norma l safety function, safety be lts work to help
keep the driver or front passenger in pos it ion in the event of a side
col lision so that the side airbags can provide protection .
T he airbag system is
not a substitute fo r your safety belt . Rather, it
is part of the overall occupant res tra in t system in your veh icle .
Always remember that the side airbag system can only help to
p rotec t you if you are wearing your safety be lt and wear ing it prop­
erly. This is another reason why you should a lways wear your safety
belts, not just because the law requires you to do so ~
page 202,
"General notes" .
I t is important to remember that while the supp lemental s ide airbag
system is designed to reduce the like lihood of ser ious injuries, other
injuries, for example, swelling, bruising, and minor abrasions can
also be assoc iated with deployed side airbags. Remember too, side
airbags wil l deploy only once and on ly in certain kinds of accidents
- your safety belts are a lways there to offer protec tion .
Vehicle damage, repair costs or even the lack of vehic le damage are
not necessarily an indicati on of over -sensitive or failed ai rbag acti ­
vation. In some collisions , both front and side airbags may inflate.
Remember too, that airbags will dep loy only once and only in
certain kinds of collisions -your safety belts are always there to
offer protection in those accidents in which airbags are not
supposed to deploy or whe n they have already deployed.
The side airbag system will not deploy :
• when the ignition is turned o ff
Safety first
Airbag sy ste m
• in side collisions when the acceleration measured by the sensor
is too low
• in front -end collisions
• in rear -end co llisions
• in ro llovers .
I n some types o f accidents the front airbags, side curtain airbags
and side airbags may be triggered together .
& WARNING
• Safety belts and the airbag system will only prov ide protect ion
when occ upants are in the proper seating position
~ page 230 .
• If the airbag indicator light come s on when the vehicle i s being
used , ha ve the sy stem inspected immediately by your authorized
Audi dealer . The airbag may not work properly when the vehicle
acceleration in a side collision is high enough to act ivate the
airbag .•
How supplemental side airbags work
Side airbags deploy instantly and c an help reduce the risk
of upper to rso injuries for occupants who are properly
restrained.

passengers to travel in this posit ion .
• Always use the built -in coat hook s only for lightweight
c lothing. Never le ave any heavy or sharp-edged objects in the
pockets that may interfere with side airbag deployment and can
c ause personal injury in an accident .
• Always prevent the side airbags from being damaged by heavy
objects knocking against or hitting the sides of the seatbacks .
• The airbag system can only be triggered once . If the airbag has
been triggered , the system must be replaced by an authorized
Audi deale rship .
• Damage (cracks , deep scratches etc .) to the original seat covers
or to the seam in the area of the side airbag module must always
be repaired immediately by an authorized Audi dealer.
• If children are seated improperly , their risk of injury incre ases
in the case of an accident=:>
page 234, "Child Safety".
• Never attempt to modify any components of the airbag system
in anyway.
• In a side collision , side airbags will not function properly if
sensors cannot correctly measure increasing air pressure inside
the doors when air escapes through larger , unclosed openings in
the door panel .
- Never drive with inter ior door tr im panels removed .
- Never drive when parts have been removed from the inside
door panel and the openings they leave have not been properly
closed.
- Never drive when loudspeakers in the doors have been
removed unless the speaker holes have been properly closed .
- Always make certain that openings are covered or filled if
additional speakers or other equipment is installed in the
