Repair , care and disposal of the airbags
Parts of the airbag system are installed at many
different places on your Audi. Installing , remov
ing, servicing or repairing a part in an area of the
vehicle can damage a part of an airbag system
and prevent that system from working properly
in a collision .
There are some important things you have to
know to make sure that the effectiveness of the
system will not be impaired and that discarded
components do not cause injury or pollute the
environment.
A WARNING
Improper care, servicing and repair proce
dures can increase the risk of personal injury
and death by preventing an airbag from de-
162
ploying when needed or deploying an airbag
unexpectedly :
- 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 airbag units .
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one mois
tened with plain water. Solvents or cleaners could damage the airbag cover or change
the stiffness 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, instrument
panel, front seats or electrical system (in
cluding 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 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 specifically approved by
Audi .
- Never use additional seat cushions that
cover the areas where the side airbags in
flate.
- Damage to the original 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 deploy only once. Af
ter an airbag has been deployed, it must be
replaced with new replacement parts de
signed and approved especially for your
Audi model version. Replacement of com
plete airbag systems or airbag components

&
Maintenance booklet under AIRBAG RE
PLACEMENT RECORD.
- For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechn ic circuit
interrupter.
- Work on the pyrotechnic circ uit interrupt
er must only be performed by a qualified
technicians who have the experience, in
formation and special tools necessary to
perform the work safely.
- If the veh icle or the c ircuit interrupter is

safety bel ts wit h pretensione rs are scrapped,
all a ppli cable laws and regulations mus t be
observed. Your a uthorized Audi dealer is fa
m iliar 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 t he Advanced Airbag System
pe rforms in a crash. For examp le, using tire-r im
comb inat ions no t approved by Audi, lowering the
ve hicle, changing the s tiffness of the suspens ion,
includ ing the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
e lectronic contro l 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
the changes had no t been made. Other kinds of
Airb ag sys tem
changes may red uce the force levels measured by
the sensors and prevent the airbag from deploy
i ng when it sho uld.
A WARNING
=
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance a nd in
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 origina lly instal
led on you r vehi cle.
- Never use tire-rim combinations that have
not been approved by Audi.

page 157 , More important things to know
about front airbags .
In addition to their normal safety function, safe
ty belts help keep the driver or front passenger in
position in a frontal collision so that the airbags
can prov ide supplemental protect ion .
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overall 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 soc::>
page 139, Gener
al information .
Remember too, airbags will deploy only once and
only in certain kinds of accidents -your safety
belts are always there to offer protect ion in those
accidents in which airbags are not supposed to
deploy or when they have already deployed, for
example when your vehicle strikes or is struck by
another after the first collis ion .
This is just one of the reasons why an airbag is
not a substitute for the safety belt. The airbag
system works most effectively when used with
the safety belts. Therefore, always wear your
safety belts correct ly.
It is important to remember that whi le the sup
p lemental knee airbag system is designed to re
duce the likelihood of serious injuries, other inju
ries, for example, swelling, bruising and minor
abras ions and friction burns can also occur when
an airbag inflates .
The knee airbag system basically consists of:
-The electronic control module
- Two inflatab le airbags (airbag and gas genera-
tor), one for the driver and one for the front
passenger
- The airbag indicator light in the instrument
panel
The knee airbag system will not deploy:
- when the ignition is switched off
164 - in frontal
collisions when the deceleration
measured by the contro l unit is too low
- in side collisions
- in rear-end collisions
- in rollovers
- in the event of a system malfunction (warning/
ind icator light is on)
<=:>page 17.
.&_ WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
th e proper seating position
c::> page 157 .
-If the airbag indicator light c::> page 17
comes when the vehicle is being used, have
the system inspected immediately by your
authorized Audi dealer.
It is possible that
the airbag will inflate when it is not sup
posed to, or will not inf late when it should.
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.
Fig. 158 Inflated a irbags protect ing in a frontal coll is io n
The knee airbag system has been designed so
that the airbags for the driver and front passen

If the front airbags deploy, the knee airbags also
deploy in frontal coll isions when the deployment
threshold stored in the control unit is met.
When the system deploys, the airbags f ill with a
prope llant gas, and inflate between the lower
part of the instrument panel and the driver and

Although they are not a soft pillow, they can
"cushion" the impact and in this way they can
help to reduce the risk of injury to the lower ex
tremities .
All of this takes place in the blink of an eye, so
fast that many people don't even realize that the
airbags have deployed . The airbags also inflate
wi th a great deal of force and it is important for
occupant safety that nothing should be in their
way when they deploy .
Fully inflated airbags in comb ination with proper
ly worn safety belts slow down and limit the o c
cupant 's forward movement and help to reduce
the r isk of injury .
Important safety instructions on the knee
airbag system
Applies to: veh icles wit h knee airbags
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 p rovide supplemental protection .
& WARNING
An inflating knee airbag can cause ser ious in
jury. Wearing safety bel ts incorrec tly and im
proper sea ting positions increase the r isk o f
serious personal injury and death whenever a
vehicle is being used.
- The knee airbag system cannot protect you
properly if you are seated too close to any of
the airbag locat ions. When ad justing their
seat positions, it is important that both the
driver and the front passenger keep their
upper bod ies a nd knees at the following
min imum safe distances :
- at least 10 inches (25 cm) between the
chest and the steering wheel/instrument
panel.
- at least 4 inc hes (10 cm) between the
knees and the lower part of the instru
ment panel.
- The risk of persona l injury inc reases if you
lean forward or to the side, or if the seat is
-
Airb ag sys tem
improperly positioned and you are not wear
ing your safety belt. The risk increases even
more should the airbag deploy.
- Always make sure that the knee a irbag can
inflate w ithout interference . Objects be
tween you and the airbag can increase the risk of injury in an acc ident by interfering
with the way the airbag deploys or by being
pushed into yo u as the a irbag deploys.
- Never let anybody, especia lly children or
anima ls ride in the footwell in front of the
passenger seat. If the airbag deploys, this
can result in serious or fatal inj uries.
- Never carry objects of any kind in the foot
well area in front of the driver's or pas
senger's seat. Bulky objects (shopp ing
bags, fo r example) can interfere with or
prevent proper dep loyment of the airbag .
Small objects ca n be thrown th rough the
vehicle if the airbag deploys and injure you
o r your passengers .
- M ake sure the re are no c rac ks, deep scratch
es or othe r damage in the area of the inst ru

Airbag system
The side airbags are located in the sides of the
front seat backrests¢
fig. 159 and the rear back
rest facing the doors. They are identified by the
word "AIRBAG".
The side airbags installed for the front seating
positions have been designed and certified to
he lp reduce the risk of injury that can be caused
by airbags when they inflate, particularly when
the occupant sitting next to it is not seated prop
erly. The side a irbag for the front passenger seat
can be used with properly installed child re
stra ints . Please be sure to read the important in
formation and warnings whenever using a child
rest raint in a veh icle: Safety belts¢
page 139,
Airbag system ¢page 147, Child safety
¢ page 171.
The side airbag system basically consists of:
-the electronic control modu le and external side
impact sensors
- the two airbags located in the sides of the front
backrests and the two airbags* located in the
rear backrest
- the a irbag warning light in the instrument clus-
ter.
The airbag system is monitored electronically to make certain that it is functioning properly at all
times. Each time you switch on the ign ition, the
airbag system indicator light will come on for a
few seconds (self diagnostics).
The s ide air bag system supplements the safety
belts and can help to reduce the risk of injury to
the dr iver's, front and rear passenger's upper tor
so on the side of the vehicle that is struck in a
side collision. The a irbag dep loys only in side im
pacts and only when the vehicle acceleration reg
istered by the control unit is high enough. If this
rate is below the reference value programmed in
to the control unit, the side airbags wi ll not be
triggered, even though the car may be bad ly
damaged as a result of the collision. It is not pos
sible to def ine an airbag tr igger ing range that
will cover every possible angle of impact, since
the circumstances will vary cons iderably between
one collision and another. Important factors in
clude, for example, the nature (h ard or soft) of
the impacti ng object, the angle of impact, vehicle
166
speed, etc. ¢ page 167, Important safety in
structions on the side airbag system .
Aside from their normal safety function, safety
belts work to help keep the driver or front pas
senger in position in the event of a side collision
so that the side airbags can provide protection .
The airbag system is
not a substitute for your
safety belt . Rather, it i s part of the overall occu
pant res traint system in your vehicle . Always re
member that the side airbag system can only
help to protect you if you are wear ing your safety
belt and wearing it properly. This is another rea
son why you should a lways wear your safety
belts, not just because the law requires you to do
so¢
page 139, General information .
It is important to remember that while the sup
plemental side airbag system is designed to re
duce the likelihood of ser ious injuries, other inju
ries, for example, swelling, bru is ing, friction
burns and minor abrasions can also be assoc iated
with deployed side airbags. Remember too, side
a irbags w ill deploy only once and only in certa in
kinds of accidents -your safety belts are always
there to offer protection.
Vehicle damage, repair costs o r even the lack of
vehicle damage are not necessarily an ind icat ion
of over-sens itive or fa iled airbag activation. In
some collisions, both front and side airbags may
inflat e. Remember too, that airbags w ill deploy
on ly once and only in certain kinds of collisions -
your safety be lts are always there to offer protec
tion in those accidents in which airbags are not
supposed to deploy or when they have already
deployed .
The side airbag system will not deploy:
- when the ignition is switched off
- in side co llisions when the acceleration meas -
ured by the sensor is too low
- in front-end collisions
- in rea r-end collisions
- in rollovers.
In some types of accidents the front airbags, side
curta in airbags and side a irbags may be triggered
together .
