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
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
150
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
must be performed by qualified workshops
only . Make sure that any airbag service ac
tion is entered in your Audi Warranty
&
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 pyrotechnic circuit
interrupter.
- Work on the pyrotechnic circuit 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 vehicle or the circuit interrupter is
scrapped, all applicable safety precautions must be followed.

rate . When the veh icle or parts of the re
straint system including airbag modules and
safety belts with pretensioners 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 System
pe rforms in a crash. For examp le, using tire-rim
comb inat ions not approved by Audi, lowering the
veh icle, 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
e lectronic control unit . Some suspension 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 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 serious 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 vehicle.
- Never use tire-rim combinations that have
not been approved by Audi.
Airbag system
Knee airbags
Description of knee a irbags
Applies to: vehicles wit h knee airbags
The knee airbag system can provide supplemen
tal protection to properly restrained front seat
occupants .
Fig. 158 Driver 's knee air bag
The driver knee airbag is in the inst rument panel
u nderneath the steering wheel¢
fig. 158, the
airbag for the passenger is at about the same
height in the instrument pane l 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 deploy, the knee airbags also
deploy in frontal collisions when the deployment
threshold stored in the control unit is met
¢ page 144, More important things to know
about front airbags .
In addition to their normal safety function, safe
ty belts help keep the dr iver or front passenger in
pos ition 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 wear ing your safety be lt
and wea ring it properly. This is why you shou ld
always wea r your safety belt, not just because
t h e law requires you to do so ¢

151
Airbag system
Remember too, airbags will deploy only once and
only in certain kinds of accidents -your safety
belts are always there to offer protection 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 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
ab rasions and friction burns can also occur when
an airbag inflates.
The knee airbag system basically consists of:
-The electronic control module
- 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 side collisions
- in rear-end collisions
- in rollovers
- in the event of a system malfunct ion (warning/
indicator light is on) ¢
page 17 .
_&, WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
the proper seating position¢
page 144.
-If the airbag indicator light ~ page 17
comes when the vehicle is be ing 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 will not inflate when it should.

How knee airbags work
Applies to : vehicles wit h knee airbags
The risk of injury to the leg area can be reduced
by fully inflated knee airbags .
Fig. 159 Inflated airbags protec ting in a fronta 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 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 fi ll with a
prope llant gas , and infla te between the lower
part of the instrument panel and the d river and
the lower part of the instrument panel and the
front passenger ¢
page 144, fig. 156.
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 th is takes pla ce 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 deploy .
Fully inflated airbags in combination with proper
ly worn safety be lts s low down and limit the oc
cupant's forward movement and help to reduce
the risk of injury.
Important safety instructions on the knee
airbag system
App lies to: ve hicles with k nee 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 be lts and airbags
to provide supplemen tal protection .
A WARNING
An inflating knee airbag can cause serious in
jury . Wearing safety belts incorrectly and im
proper seating positions increase the risk of
ser ious 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 a irbag locat ions. When adjusting their
seat positions , it is important that both the
driver and the front passenger keep their
upper bod ies a nd knees at the followi ng
min imum safe distances :
- at least 10 inches (25 cm) between the
chest and the steering wheel/instrument
panel.
- at least 4 inches (10 cm) between the
knees and the lower part of the instru
ment panel.
- The risk of personal injury increases if you
lean forward or to the s ide, or if the seat is
improperly positioned and you are not wear
ing your safety belt . The risk increases even
more should the a irbag deploy.
- Always make sure that the knee airbag can
inflate without inte rference . Objects be
tween you and the a irbag can increase the
risk of i nju ry in an accident by interfer ing
w ith the way t he a irbag deploys o r by being
pushed into you as the airbag deploys .
- Never let anybody, especially chi ldren or
animals ride in the footwell in front of the
passe nger seat. If the airbag deploys, this
can resu lt in se rious or fatal injur ies.
- Never carry objects of any k ind in the foot
well area in front of the driver's or pas
senger's seat . Bu lky objects (shopping
-
Airb ag sys tem
bags, for example) can interfere 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
es or other damage in the area of the instru
ment panel where the knee airbags are lo
cated.
- If c hildren are incorrectly seated, their risk
of injury inc reases in a coll is ion

Fi g. 160 Side airb ag locat io n in t he drive r's sea t
The side airbags are located in the s ides of the
front seat backrests ¢
fig. 160 and the rear back
rest fac ing the doors . They a re identified by the
word "AIRBAG".
The side airbags installed for the fro nt seating
pos it ions have been des igned and certified to
help reduce the risk of inju ry that can be caused
by a irbags when they inflate, pa rtic ularly when
t h e occ upant sitting next to it is not seated prop

-the e lectronic contro l 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 airbag warning light in the instrument cl us-
ter.
The airbag system is monitored electronically to make certa in that it is functioning properly at all
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 help 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 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 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
sible to def ine an airbag tr iggering range that
will cover every possible ang le of impact , since
the circumstances wi ll vary considerably betw een
one co llision and another. Important factors in
clude, for example, the nature (hard or soft) of
the impacting object , the angle of impact , vehicle
speed, etc.¢
page 155, 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

so that the side a irbags can provide protection .
The airbag system is
not a substitute for your
safety belt. Rather, it is part of the overall occu

burns and m inor abras ions can also be assoc iated
with deployed side airbags. Remember too, side
airbags will dep loy only once and only in certain
k inds of acc idents -your safety belts are always
there to offer protection .
Vehicle damage, repair costs or even the lack of
vehicle damage are not necessar ily an ind ication
of over -sens itive or fa iled airbag activat ion. In
some collisions, both front and side airbags may
i nflate . Remember too, that a irbags w ill dep loy
o nl y once and on ly in certain kinds of collisions -
you r 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 a lready

The s ide airbag system will not deploy:
- when the ignit io n is switched off
- in side co llisions when the acceleration meas-
ured by the sensor is too low
- in front-end coll is ions
- in rear-end collisions
-in rollovers .
In some types of accidents the front ai rbags, side
curtain airbags and side airbags may be triggered
together .
A WARNING
-Safety belts and the airbag system will only
provide protect ion when occupants are in
the proper seating position ¢
page 155 .
-If the airbag ind icator light¢ page 17
comes when the veh icle is being used, have
the system inspected immediately by your
author ized Audi dealer . It is possible that
the airbag will inflate when i t is not sup
posed to, or wi ll not inflate when it should.
How supplemental side airbags work
Side airbags deploy instantly and can help reduce the risk of upper torso injuries for occu
pants who are properly restrained.
F ig . 161 In fla ted side airbags o n left s ide of v ehicle , rea r
side a irbag
When the system is triggered, the a irbag is filled
with propellant gas and breaks through a seam in the seat surface area marked "AIRBAG ". It ex
pands between the s ide trim pane l and the pas
senger. In order to he lp prov ide this add itiona l
p rotection, the side airbag must inflate within a
fraction of a second at very high speed and with great force . The supplemental side airbag could
injure you if your seating position is not proper or
upright or if items are located in the area where
the supplemental side airbag expands . This ap
p lies especially to children
