Repair, care and disposal of the airbags
Parts of the a irbag system are installed at many
d iffe rent p laces on your Audi. Insta lling, remov
ing, servicing or repa iring a part in an area of the
veh icle can damage a part of an ai rbag system
and prevent that system from working properly
in a co llision.
There are some important thi ngs you have to
know to make sure that the effect iveness of the
system w ill not be impaired and that d isca rded
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 a irbag from de
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 pane l or modify them in any way.
- Never attach any objects such as cup holders or te lephone mountings to the surfaces cov
ering the airbag units.
- For cleaning the ho rn pad or instrument
panel, use only a soft, dry cloth or one mois
tened with plain water. So lvents or cleaners
c ould damage the a irbag cover or change
the stiffness o r strength of the ma ter ial so
that the airbag cannot dep loy and protect
properly .
- Never repa ir, adjust, or change any parts of
the a irbag system.
- All work on the stee ring wheel, inst rument
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
158
who has the training and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that yo u 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 w ithout interference:
- Never install seat covers or rep lacement
u pholstery over the front seatbacks that
have not been specifically approved by
A udi.
- Never use additional seat c ushions that
cover the areas where the side a irbags in
flate.
- Damage to the orig inal seat cove rs or to
the seam in the are a of the side ai rbag
module mus t always be repaired immedi
ate ly by an autho rized Aud i dealer.
- The a irb ag sys tem can deploy on ly on ce. Af

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced A irbag System
performs in a crash. For example, using tire-rim
comb inat ions not approved by Audi, lowering the
vehicle, changing the stiffness of the su spension,
including the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
e lectronic control un it. Some suspension changes
can, for example, increase the force levels meas
ured by the sensors and make the airbag system
deploy in crashes in which it would not deploy if
the changes had not been made . Other kinds of
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy
ing when it should.
_& WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in
crease the risk of ser ious personal injury in a
crash.
- Never install suspens ion components that
do not have the same performance charac
teristics as the components originally instal
led on your veh icle.
- Never use tire-rim combinations that have
not been approved by Audi.
Airbag system
Knee airbags
Description of knee a irbags
Applies to vehicles: with knee airbags
The knee airbag system can provide supplemen
tal protection to properly restrained front seat
occupants .
Fig. 161 D river 's knee a irbag
T he driver knee airbag is in the instrument panel
underneath the steering wheel
¢fig.161, the
airbag for the passenger is at about the same
height in the instrument panel underneath the
glove compartment.
The knee airbag offers additional protection to
the driver's and passenger's knees and upper and
lower thigh areas and supplements the protec
tion provided by the safety belts.
If the front airbags dep loy, the knee airbags also
deploy in frontal collisions when the dep loyment
threshold stored in the control unit is met
¢ page 152 , 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 provide supplemental protection .
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 a l
ways wear your safety belt, not just because the
law requires you to do so¢

Airbag system
Remember too, airbags will deploy only once and
only in certain kinds of accidents -your safety
be lts are always there to offer protection in those
accidents in which airbags are not supposed to
deploy or when they have already deployed, for
examp le when your vehicle strikes or is struck by
another after the first collision .
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 correctly .
It is important to remember that while the sup
plemental knee airbag system is des igned to re
duce the likelihood of serious injuries, other inju
ries, for example, swelling, bruising and minor
abrasions and friction burns can also occur when
an airbag inflates.
The knee airbag system basically consists of:
-The electronic control modu le
- Two inflatable 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
- in frontal collisions when the deceleration
measured by the control unit is too low
- in s ide collisions
- in rear-end collisions
- in rollovers
- in the event of a system malfunct ion (warning/
indicator light is on) ¢
page 18.
.&, WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
the proper seating position
¢page 152.
-If the airbag indica tor lig ht ¢page 18
comes when the vehicle is being used, have
the system inspected immediate ly by your
authorized Audi dealer. It is possible that
the airbag will inf late when it is not sup
posed to, or w ill not inflate when it should.

How knee airbags work
App lies to vehicles: wi th kne e airbags
The risk of injury to the leg area can be reduced
by fully inflated knee airbags .
Fig. 162 Inflated airbags protect ing in a frontal collis ion
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 fronta l co llisions .
If the front airbags deploy, the knee airbags also
deploy in frontal collisions when the deployment
threshold stored in the control unit is met.
When the system deploys, the airbags fill with a
propellant gas, and inflate between the lower
part of the instrument panel and the driver and
the lowe r part of the instrument panel and the
front passenger ¢
page 152, fig. 159.
Although they are not a soft pillow, they can
"c ushion" the impact and in this way they can
help to reduce the risk of injury to the lower ex
tremities .
A ll 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
with a great deal of force and it is important for
occupant safety that nothing should be in their
way when they dep loy .
F ull y inflated airbags in combination with proper
l y worn safety belts s low down and limit the oc
cupant's forward movement and help to reduce
the risk of injury .

Airbag syste m
-the e lectronic control module 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 ai rbag warning light in the inst rument cl us-
ter .
The a irbag system is monitored electron ica lly to
make certa in that it is function ing properly at a ll
times. Each time you switch on the ignition, the
airbag system indicator light will come on for a
few seconds (self diagnostics).
The s ide a irbag system supplements the safety
be lts and can he lp to reduce the risk of injury to
the driver 's, front and rear passenger 's upper tor
so on the side of the vehicle that is struck in a
side collision. The airbag deploys only in side im
pacts and on ly when the vehicle accelera tion reg
istered by the control unit is high enough . If this
rate is below the reference value programmed in
to the contro l unit , the side airbags will not be
tr iggered, even though the car may be badly
damaged as a result of the co llision.
It is not pos
sible to def ine an a irbag tr igger ing range that
will cover every possible angle of impact, since
the circumstances wi ll vary considerably between
one co llision and another. Important factors in
clude, for example, the nature (hard or soft) of
t he impacting object, the angle of impact, vehicle
speed, etc. ¢
