Repair , care and disposal of the airbags
Parts of the airbag 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
veh icle can damage a pa rt of an airbag 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 w ill not be impaired and that discarded
components do not cause injury or pollute the
environment .
,& 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 deploying an airbag
unexpectedly:
282
- 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 a irbag un its.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one mois
tened w ith plain water. Solvents or cleaners
could damage the airbag cover or change
the st iffness 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, inst rument
panel, front seats or e lectr ica l system ( in
cluding the instal lation of a udio eq uipment,
cellular telephones and CB radios, etc.)
m ust be performed by a qualified technician
who has the training and specia l equipment
necessary.
- For any work on the airbag system, we strong ly 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 specif ica lly approved by
A udi.
- Never use additional seat c ushions that
cover the areas where the side airbags in
flate.
- Damage to the orig inal seat cove rs or to
the seam in the area of the s ide airbag
module mus t always be repai red immedi
ate ly by an authorized Audi dealer.
- The a irbag sys tem can deploy on ly once. Af
ter an airbag has been deployed, it m ust be
replaced with new replacement parts de
signed and approved especia lly for your
Audi model version . Replacement of com
plete airbag systems or airbag components
must be performed by qua lified workshops
only . Make sure that any airbag service

safety belts with pre tensioners are scrapped,
all applicable laws and regulations must be
observed. Your authorized Audi dealer is fa
miliar with these requirements and we recom
mend that you have your dealer perform this
service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys tem
performs in a crash. For examp le, using tire-r im
combinations not approved by Audi, lowering the
vehicle, changing the stiffness of the suspension, including the springs , suspension struts, shock
absorbers etc. can change the forces that are
measured by the airbag sensors and sent to the
electronic control unit . Some suspens ion changes
can, for example, increase the force levels meas
ured by the sensors and make the airbag system
deploy in crashes in wh ich it would not dep loy if
t he changes had no t been made. Other kinds of
changes may reduce the force levels meas ured by
the sensors and prevent the airbag from deploy ing when it should.
.&_ WARNING
Changing the vehicle 's s uspension incl uding
use of unapproved tire-rim combinations can
change Advanced A irbag performance and in-
Airb ag sys tem
crease the risk of serious personal injury in a
crash.
- Never install suspension components that
do not have the same performance charac
ter istics as the components originally instal
led on your vehicle.
- Never use tire-rim combinations that have
not been approved by Audi.

Airbag syste m
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overa ll occu
pant restraint system in your vehicle. Always re member that the airbag system can only help to
protect you if you are wearing your safety belt
and wearing it properly . This is why you should
always wear your safety belt, not just because
the law requires you to do
so ¢ page 258, Gener
al notes.
Remember too, airbags will deploy only once and
only in certain k inds of accidents
-your safety
be lts are always there to offer protection in those
accidents in wh ich airbags a re not supposed to
deploy or when they have already deployed, for
examp le when your vehicle str ikes or is struck by
another after the first collision .
This is just one of the reasons why an airbag is
not a substi tute for the safety belt. The a irbag
system works most effectively when used with
the safety belts. Therefore, a lways wear your
safety belts correct ly.
It is important to remember that whi le the sup
p lemental knee a irbag system is des igned to re

How knee airbags work
Applies to: vehicles with knee airbags
The risk of injury to the leg area can be reduced
by fully inflated knee airbags.
F ig . 246 Inflated a irbags protec ting in a fro nta l co llis io n
The knee airbag system has been designed so
that the airbags for the driver and front passen
ger dep loy in certain but not all frontal collisions .
If the front airbags deploy, the knee airbags also
deploy in frontal collisions when the dep loyment
threshold stored in the control unit is met.
When the system deploys, the a irbags f ill with a
compressed propellant gas, and inf late between
the lower part of the instrument panel and the
driver and the lower part of the instrument panel
and the front

Important safety instructions on the knee
airbag system
A ppl ies to: ve hicles with knee a irbags
Airbags are only supplemental restraints. Always
wear safety belts correctly and ride in a proper
seating position.
There is a lot that you and your passengers must
know and do to help the safety belts and airbags
to provide supplemental protection .
A WARNING
An inflating knee airbag can cause ser ious in
jury. Wearing safety belts incorrectly and im
proper seating posit ions increase the r isk of
ser ious personal inj ury and death whenever a
vehicle is being used .
- The knee airbag system cannot protect you
prope rly if you are seated too close to any of
the a irbag lo cat ions. When ad justing thei r
seat positions, it is important that both the
dr iver and the front passenger keep their
upper bodies and knees at the following
min imum safe distances:
- at least 10 inches (25 cm) between the
chest and the steer ing wheel/ins trument
panel.
- at least 4 inches (10 cm) between the
knees a nd the lower pa rt of the instru
ment panel.
- T he risk of persona l injury inc reases if you
lean forward or to the s ide, or if the sea t is
imp roperly posi tioned and you are not wear
ing your safety belt . The risk increases even
more should the airbag deploy .
- Always make sure tha t the knee airbag can
inflate without interference. Objects be
tween you and the airbag can increase the risk of inj ury in an accident by inter fer ing
-
Airb ag sys tem
with the way the airbag deploys or by being
pushed into yo u as the a irbag deploys.
- Neve r let anybody, especia lly children or
anima ls r ide in the footwell in front of the
passenger seat. If the airbag deploys, this
can result in serious or fatal i njuries.
- Neve r carry objects of any kind in the foot
well a rea in front of the driver's or pas
senger 's seat . Bulky objects (shopp ing
bags, for example) can i nterfere with or
prevent proper dep loyment of the airbag .
Small objects can be thrown through the
vehicle if the airbag deploys and injure you
or your passengers.
- Make sure there are no cracks, deep scratch

rate is below the reference value programmed in
to the control un it, the side airbags w ill not be
tr iggered , even though the car may be bad ly
damaged as a result of the collision.
It is not pos
sib le to define an a irbag tr igger ing range that
will cover every possible ang le of impact , since
