Repair, care and disposal of the airbags
Parts of the a irbag system are installed at
many different places on your Audi. Installing,
removing, servicing or repairing a part in an
a rea of the vehicle can damage a part 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 effect iveness of
the system will not be impaired and that dis
carded components do not cause injury or po l
lute the environment.
A WARNING
Improper care, servicing and repair proce
dures can increase the risk of personal in
jury and death by preventing an airbag from deploy ing when needed or deploying
an airbag unexpectedly:
- Never cover, obstruct, or change the steering wheel ho rn pad or airbag cover
or the instrument pane l or modify them
in any way .
- Never attach any objects such as cup
holders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
pane l, use only a soft, dry cloth or one
moistened w ith plain water. Solvents or
cleaners cou ld damage the airbag cover
or change the stiffness or strength of the material so that the airbag cannot de
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system.
- All work on the steering wheel, instru
ment panel, front seats or electr ica l sys
tem (including the installation of audio
equ ipment, cellu lar telephones and CB
radios, etc .) must be performed by a
qualified technic ian who has the training
and specia l equipment necessary.
- For any work on the airbag system, we strongly recommend that yo u see your
author ized Audi dealer or qualif ied work
shop.
- Never modify the front b umper or parts
of the vehicle body.
- Always make sure that the s ide airbag
can inflate without inte rfe rence:
- Never install seat covers or rep lace
ment upholstery over the front seat
backs that have not been specifically
approved by Audi.
- Never use additional seat c ushions that
cover the areas where the side airbags
inflate.
- Damage to the orig inal seat covers or
to the seam in the area of the side a ir
bag module must a lways be repaired
immediately by an author ized Audi
dealer .
- The airbag system can deploy on ly once.
After an a irbag has been deployed, it
must be replaced w ith new replacement
pa rts des igned and app roved especially
for your Aud i model version. Replace
men t of comple te airbag systems or air
bag components must be performed by
qua lified wor kshops only . Make sure that
any airbag service action is entered in
your Aud i Warranty

The knee airbag offers additiona l protect ion
to the driver's and passenger's knees and up per and lower thigh areas and supp lements
the protect ion provided by the safety belts.
I f the front airbags deploy, the knee airbags
a lso deploy in frontal co llisions when the de
p loyment threshold stored in the contro l unit
is met
c:> page 152, More important things to
know about front airbags.
In addition to their normal safety function,
safety belts he lp keep the driver or front pas
senger in posit ion in a frontal collis ion so that
the airbags can prov ide supplemental protec
tion .
The airbag system is not a subst itute for your
safety belt. Rather, it is part of the overall oc
cupant restraint system in your veh icle. Al
ways remember that the airbag system can
only help to protect you if you are wearing
your safety be lt and wear ing it properly . Th is
is why you shou ld always wear your safety
be lt, not just because the law requires yo u to
do so
<:> page 133, General notes.
The safety belt buck le for the dr iver and front
seat passenge r have switches that te ll t he a ir
bag control mod ule if the safe ty belt is being
used or no t. If the safety be lt is being used,
the knee airbag will deploy at a slightly higher rate of deceleration than if the belt is not be
ing used. Therefore, in a partic ular collision, it
is possible that an airbag will not deploy at a
seating position where the safety belt is being used but will inflate at the position where the
safety belt is not be ing used.
Remember too, airbags will deploy only once
and only in certain kinds of accidents -your
safety be lts are always there to offer protec
tion in those acc idents in which a irbags a re
not supposed to deploy or when they have a l
r eady deployed, fo r example whe n your veh i
cle strikes or is str uck by another after the
first coll is ion .
This is just one of the reasons why an a irbag is
n ot a substitute for the safety belt. The airbag
sys tem works mos t effective ly when used wi th the safety be
lts. Therefore, always wear yo ur
safety be lts correct ly .
It is important to remembe r that w hile the
s u pplement al knee airbag system is designed
to reduce the likelihood of ser ious inju ries,
other injuries, for example, swelling, bruising,
minor ab rasions and friction b urns can a lso
occur when an airbag inflates.
The knee airbag sy stem basically consist s
of:
-The e lectronic control module
- Two inflatable ai rbags (airbag and gas gen -
erator), one for the driver and one for the
front passenger
- The airbag indicator lig ht in the instrument
pane l
The knee airbag system will not deploy:
-when the ignit ion is swit ched off
- in frontal collisions when the deceleration
measured by t he control un it is too low
- in side co llisions
- in rear-end col lisions
- in rollovers
- in the event of a system malfunction (warn-
ing/ind icator light is on)
<:> page 18.
A WARNING
-Safety belts and the airbag system can
only provide protection when occupa nts
are in the proper seating position
<:>pag e 152 .
- If the airbag ind icator light comes when
the vehicle is be ing used, have the sys
tem inspected immediate ly by you r au
thori zed A udi dealer. The airbag may not

It is important to remember that while the
supp lemental s ide airbag system is designed
to reduce the like lihood of serious injur ies,
other i njuries, for example, swel ling, b ruising,
frict ion bu rns and minor ab rasions can also be
assoc ia ted with deployed side airbags. Re
member too, side airbags will deploy only
once and only in certain kinds of accidents -
your safety belts are always there to offer pro
tection.
Vehicle damage, repa ir costs or even the lack
of vehicle damage are not necessar ily an indi
cation of over-sensitive or failed airbag activa
tion. In some co llisions, both front and side
airbags may inflate. Remember too, that air
bags will dep loy only once and only in certain
kinds of collisions -your safety belts are al
ways there to offer protection in those acci
dents in wh ic h airbags are not supposed to
deploy or when they have already deployed.
The side airbag sy stem will not deploy :
-when the ign ition is switched off
- in s ide collisions when the acceleration
measured by the sensor is too low
- in front-end collisions
- in rear -end collisions
- in ro llovers.
In some types of acc idents the front airbags,
side curta in a irbags and side airbags may b e
tr iggered toge ther.
_& WARNING
- Saf ety belts and the a irbag system will
only prov ide protection when occ upan ts
are in the proper seating posit ion

Side curtain airbags
Description of side curtain airbags
The side curtain airbag system can provide
supplemental protection to properly restrain
ed occupants.
Fi g. 152 Side curtai n airbags, dri ver 's s ide: side cu rtai n
ai rbag locat ion
The side curtain airbags are located on both
sides of the interior above the front and rear
side windows ¢
fig. 152 . They are identified
by the word "AIRBAG" on the windshie ld
frame and the center roof pillar.
The s ide curtain airbag system supplements
the safety belts and can help to reduce the
risk of injury for occupa nts' heads and upper
torso on the side of the veh icle tha t is struc k
Airba g system 165
in a side collision. The side cu rtain airbag in
flates in side impacts and only when the vehi
cle acceleration registered by the control un it
is h igh eno ugh. If this rate is below the refer
ence value programmed into the control unit,
the side airbags will not be triggered, even
though the car may be badly damaged as a re
sult of the co llision . It is not possib le to de
fine an airbag triggering range that will cover every possib le ang le of impa ct, sin ce the cir
c u mstances will vary cons iderably be tween
one collision and anothe r. Important factors
incl ude , for example, the nature (hard or soft)
of the impacting object, the ang le of impact,
vehicle speed, etc. ¢
page 166, How side cur
tain airbags work.
Aside from their normal safety function, safe
ty belts work to help keep the driver or front passenger in position in the event of a colli
s ion so that the side curtain airbags can pro
vide protection .
The airbag system is not a substit ute for your
safety belt. Rather, it is part of the overall oc
cupant restraint system in your vehicle. Al
ways remember that the a irbag system can
o nly help to protect you if you are wear ing
you r safety be lt and wearing it proper ly. This
i s a nothe r reason why you should a lways wear
your sa fe ty be lts, no t ju st because the law re
quires you to do so ¢
page 133, General
notes .
It is important to remember that wh ile the
s ide cu rtain air bag system is desig ned to help
reduce the likelihood of serious injuries, other
injur ies, for examp le, swelling, bruising, fric
tion burns and minor abrasions can also be as
sociated w ith these airbags upon dep loyment.
Remember too, these airbags will deploy only
once and only in certain kinds of accidents -
your safety belts a re always there to offer pro
tection .
The side curtain airbag sy stem basic ally
consists of :
- The electronic control module and external
side impact sensors
ll>-
166 Airbag system
-The side curtain ai rbags above the front and
rear s ide windows
- The airbag indicator light in the instrument
panel
The airbag system is monitored electron ica lly
to make certain it is f unct io ning 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 side curtain airbag is not activated:
- if the ignit io n is switched off,
- in s ide coll isions when the accelerat ion
measured by the sensor is too low,
- in rear-end collisions .
A WARNING
-Safety belts and the a irbag system w ill

¢ page 50, General recommendations.
- If the airbag indica tor ligh t comes on
when the veh icle is being used, have the
system inspected immediately by your
authorized Audi dealer. The side curtain
airbag may not work properly even when
the vehicle acceleration in a side coll is ion
is h igh enough to activate the airbag .
How side curtain airbags work
Side curtain airbags can work togeth er with
side airbags to help reduce the risk of head and upper torso injurie s for occupants who
are properly res trained.

When the system is triggered, the side curtain
airbag is filled with prope llant gas and breaks
through a seam above the front and rear side
windows identified by the AIRBAG label. In or
der to he lp provide this additional protec tion,
the side curta in a irbag must inflate within the
blink of an eye at ve ry high speed and with
great fo rce . The side curta in a irbag could in
jure you if your seating posit ion is not prope r
