adult is properly seated and restrained at
one of the rear seating positions.
- Have the airbag system inspected by
yo ur Audi dealer before transporting
anyone on the front passenger seat.
(D Tips
If the capacitive passenger detection sys ­
tem determines that the front passenger
seat is empty, the frontal airbag on the
passenger side will be turned off, and the
P ASS ENGER AIR B AG OFF light will stay
on.
Repair, care and disposal of the airbags
Parts of the a irbag system are installed at
many different places on your Audi. Installing,
removing, servic ing or repairing a part in an
area of the vehicle can damage a part o f 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 tha t dis ­
carded components do not cause injury or po l­
l ute the env ironment.
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 o r deploying
an airbag unexpected ly:
- Never cover, obstruct, o r change the
steering wheel ho rn pad or airbag cover
o r th e 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 ho rn pad or instrumen t
pane l, use only a soft, d ry cloth or one
mois tened w ith plain wate r. Solven ts or
cleaners co uld damage the airbag cover
or change the stiffness o r strength of the
A irbag sys tem 153
material so that the airbag cannot de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the a irbag system.
- All work on the steering wheel, instru­
ment panel, front seats or e lectr 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 bumper or pa rts
of the vehicle body.
- Always make sure that the s ide a irbag
can inflate without inte rfe rence:
- Never in.stall 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 a irbags
i nflate.
- Damage to the orig inal seat cove rs or
to the seam in the area of the side a ir­
bag module must a lways be repaired
i mmediately by an author ized Audi
dealer.
- The airbag system can deploy on ly once.
After an a irbag has been deployed, it
m ust be replaced with new replacement
pa rts des igned and app roved espec ially
for your Aud i mo del ve rsion. Replace­
men t of comple te airbag systems or air­
bag components must be performed by
qualified workshops only . Make sure that
any airbag service action is entered in
your Audi Warranty
& Maintenance book­
let under
AIRBAG REPLACEMENT RE­
CORD.
- For safety reasons in severe accidents,
the alternator and starter are separated from the veh icle battery with a pyrotech-
nic circuit inte rrupte r. .,.. •

-Work on the pyrotechnic circu it inter­
rupter must on ly be performed by a
qua lified technicians who have the ex­
perience, information and special tools necessary to perform the work safely .
- If the vehicle or the c ircuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.
@ For the sake of the environment
Undeployed airbag modules and preten­
sioners might be classified as Perchlorate Material -special handling may apply, see
www .dtsc.ca .gov/hazardouswaste/per­
chlora te. When th e vehicle o r parts of the
restraint system including airbag modules
a nd safety bel ts w ith p retens ioners are
scrapped, all applicable laws and regula­
tions must be observed. Your authorized
Audi dea ler is familiar wit h these requ ire­
ments and we recommend that you have
your dealer perform this serv ice for you .
Other things that can affect Advanced
Airbag performance
C hanging the vehicle's suspension system can
ch ange the way th at the Advanced A irbag Sys ­
tem pe rforms in a crash. For example, using
tire -rim combinations not app roved by Audi,
lowering the vehicle, changing the stiffness of
the suspension, incl uding the springs, s uspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the a irbag
sensors and se nt to the electron ic control
u ni t. Some suspension changes ca n, for exam­
p le, increase th e forc e levels meas ure d by t he
se nsors a nd make the airbag system deploy in
crashes in w hich it would not dep loy if the
cha nges had not been ma de. Ot her kinds of
cha nges may reduce the force levels meas ­
ured by the sensors and prevent the airbag
from deploy ing when it sho uld.
The sen so rs in the safety belt buckle fo r th e
driver an d front passenger seat tell the elec ­
tronic control module if the safety belt is
latched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high- er rate of ve
hicle deceleration than i f the safe ­
ty belt is not being used. Therefore, in a par­
t icu lar coll is ion, it is possible that an airbag
will not deploy at a seat ing pos ition w here the
safety belt is be ing used but will inflate at the
pos ition where t he safety belt is not be ing
u sed. It is important that noth ing interfere
with the safety be lt buckles so that the s en­
sors can send the correct info rmation abou t
sa fe ty belt use to the elec troni c con trol un it .
A WARNING
-Changi ng the vehicle's suspension includ ­
ing use of unapp roved tire -rim combina ­
tions can change Advanced Airbag per­
formance and increase the r isk o f serious
personal injury in a crash.
- Never install suspension components
that do not have the same performance
characterist ics as the components orig i­
na lly installed on your vehicle .
- Never use tire-rim combinations that
have not been approved by Audi.
Knee airbags
Description of knee airbags
Applies to vehicles : wi th knee airbags
The knee airbag system can provide supple­
mental prot ection to properly restrained
front seat occupants.
Fi g. 14 5 Driver"s air bag
The driver knee airbag is in the instrument
panel underneath t he steering wheel
Q fig . 145, the airbag for the passenger is at
about the same height in the instrument pan-
el underneat h the glove compartment . ...,

The knee airbag offers additional 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
also deploy in fronta l collisions when the de ­
p loyment threshold stored in the control unit
is met c>
page 147, More important things to
know about front airbags.
In addition to their normal safety function,
safety be lts he lp keep the driver or front pas ­
senger in posit ion in a frontal coll is ion so that
the airbags can prov ide supplemental protec­
tion .
The airbag system is not a subst itute for yo ur
safety be lt. 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 wea ring
your safety belt and wear ing it prope rly . T hi s
i s why you shou ld always wear you r safety
be lt, not just because the law requires yo u to
do soc>
page 128, General notes.
The safety belt buck le for the dr iver and front
seat passenge r have switc hes that tell the a ir­
bag con trol mod ule if the safety belt is be ing
used or not . If the safety belt 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 particu lar collision, it
is poss ible that an airbag will not deploy at a
seating position where the safety belt is being
used but will inflate at the position whe re the
safety belt is not be ing used.
Remember too, airbags will deploy only once
and only in certain kinds of accidents -your
safety belts 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 s truck by another afte r the
fi rst coll is ion .
This is just one of the reasons why an a irbag is
n ot a substi tute fo r the safety belt. The airbag
sys tem works most effective ly when used with
A irbag system 15 5
the safety belts. Therefore, always wear yo ur
safety belts correct ly .
I t i s important to remembe r that w hile the
s u pplementa l knee airbag system is designed
to reduce the likelihood of ser ious injuries,
other injuries, for example, swelling, bruising,
minor abrasions and friction b urns can a lso
occur when an airbag inflates.
The knee airbag system basically consists
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 ai rbag indicator lig ht in the i nstrument
pane l
The knee airbag system will not deploy:
-when the ignit io n is switched off
- in frontal collisions when the deceleration
measu red by t he con trol un it is too low
- in side co llisions
- in rear-end collisions
- in rollovers
- in the event of a system malfunction (warn-
ing/ind icator light is on)
c> page 17.
A WARNING
- Safety belts and the airbag system can
only provide protection when occupants
are in the proper seating position
i=>page 147.
- 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
wo rk properly when the vehicle acce le ra­
tion in a side co llision is high enough to
deploy the airbag . See also

of the passenger seat. If the airbag de­
p loys, this can resu lt in serious or fata l
injuries.
- Never carry objects of any kind in the
footwell area in front of the driver's or passenger's seat. Bulky objects (shop­
p ing bags, for e xample) ca n interfere
with or prevent proper dep loyment of
the airbag . Small objects can be
thrown throug h the vehicle if the ai r­
b ag deploys and injure you o r yo ur pas­
sengers.
- Make su re there are no crac ks, deep
scratches or other damage in the area of
the instrument pane l where the knee air­
bags are located.
- If children are incorrect ly sea ted, their
risk of i njury increases in a collision

The s ide a irbags installed for the front seating
positions have been designed and cer tified to
he lp red uce the risk of i nju ry that can be
caused by airbags when they inflate, particu ­
l arly when the occupant sitting next to it is
not seated proper ly . The side airbag for the
front passenger seat can be used with proper-

The side airbag sy stem basically consi st s of:
- t he electro nic cont ro l modu le and external
side impact sensors
- t he two a irbags located in the s ides of the
front backrests and the two a irbags* loc ated
in the rear backrest
- t he airbag warning light in the ins trumen t
cl uste r.
T he airbag system is mon itored e lec tronically
to make ce rtain that it is f unction ing p roperly
at all times. Each time you sw itch o n the igni­
tion, the airbag system ind icator light will
come on for a few seconds (self diagnostics) .
T he side airbag system supplements the safe ­
t y bel ts a nd can help to red uce the risk of in­
j u ry to the dr iver's, fron t and re ar passenger's
u pper torso on the side of the veh icle t hat is
str uck in a side collision . The airbag dep loys
only in side impacts and only when the vehicle
acce lerat ion reg istered by the control unit is
high enough. If this rate is below the refer­
ence value programmed into the co ntrol unit,
the side airbags w ill not be triggered, even
though the car may be bad ly damaged as a re­
su lt 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 impact, s ince the cir­
cumstances will vary considerably be tween
one collisio n and another . Important factors
include, for example , the nature (hard or soft)
of the impacting objec t, the angle of impact,
vehicle speed, etc .
¢ page 159, Impor tan t
safety instructions on the side airbag system .
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 side
collision so that the side airbags can provide protection .
The airbag system is
no t a substitute for your
safety belt. Ra ther, it is part of the overall oc-
cupant restra int system in your vehicle .

158 Airbag system
A lways remember that the side airbag system
can only help to protect you if you are wearing
your safety belt and wear ing it properly. This
is another reason w hy you should always wear
your safety belts, not just because the law re­
qu ires you to do so
Q page 128, General
notes.
It is important to remember that while the
supplemental side a irbag system is designed
to reduce the likelihood of serious injur ies,
other inju ries, fo r example, swell ing, b ruising,
frictio n burns and mi nor abrasions can also be
associa ted with deployed side airbags. Re ­
member too, side air bags will deploy only
once and only in certain k inds of accidents -
your safety be lts 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
a irbags 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 air bags are not supposed to
deploy or when they have already deployed.
The side airbag syst em 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 col lisions
- 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 be
tr iggered together.
.&_ WARNING
- Sa fety belts and t he ai rbag sys tem w ill
only prov ide p rotec tion when occ upants
are in t he proper seating posit ion
Qpage 159.
- If the airbag indicator light comes on
when the vehicle is being used, have the
-
system inspected immediately by your
author ized Audi dealer. The airbag may
not work proper ly when the vehicle ac­
celeration in a side coll is ion is high
enough to activate the a irbag.
How supplemental side airbags work
Side airbags deploy instantly and can help re­
duce the risk of upper torso injuries for occu­
pants who are properly restrained .
Fig. 148 In flated side airbags on left s ide of vehicle,
r ear side a irbag
When the system is triggered, the airbag is
filled with propellant gas and breaks through
a seam in the seat su rface area marked "AIR­
BAG". It expands between the side trim panel
and the passenger. In order to help provide
t hi s addit ional protect ion, the side airbag
mus t inflate with in a fra ction of a second a t
very h igh speed and with great force. The sup­
pleme nta l side airbag could injure you if your
seat ing position is not proper or up right or if
items are located in the area where the sup­
plementa l side airbag expands. This applies
especially to children

ty .
Supplemental side airbags inflate between
the occupant and the door panel on the s ide

Although they are not a soft pillow, they can
"cushion" the impact and in this way they can
help to reduc e the risk of inju ry to the upp er
part of the body.
A fine dust may deve lop when the airbag de­
ploys . This is normal and does not mean there
is a fi re in th e vehicle.

Important safety instructions on the
side airbag system
Airbags are only supplemental restraints. Al­
ways properly wear safety belts and ride in a
proper seating position.
There is a lot that you and your passengers
must know and act accordingly to help the
safety belts and airbags do their job to pro­
vide supplemental protection .
A WARNING
An inflating side airbag can cause serious
or fatal injury. Improperly wearing safety
belts and improper seating positions in­
crease the risk of serious personal injury
and death whenever a vehicle is being
used .
- In order to reduce the risk of injury when
the supplemental side airbag inflates:
-Always sit in an upright position and
never lean against the area where the
supplemental side airbag is located.
- Never let a child or anyone else rest
their head against the side trim panel
in the area where the supplemental
side airbag inflates.
- Always make sure that safety belts are worn correctly,
- Do not let anyone sitting in the front
seat put their hand or any other parts
of their body out of the window.
- Always make sure that the side airbag can inflate without interference.
- Never install seat covers or replace ­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
deploy.
- Damage to the original seat covers or
to the seam in the area of the side air­ bag module must always be repaired
immediately by an authorized Audi
dealer.
Airbag system 159
- Objects between you and the airbag can
increase the risk of injury in an accident
by interfering with the way the airbag
unfolds or by being pushed into you as
the airbag inflates.
- Never place or attach accessories or
other objects (such as cup holders, tel­
ephone brackets, or even large, bulky
objects) on the doors, over or near the
area marked "AIRBAG" on the seat backrests .
- Such objects and accessories can be­ come dangerous projectiles and cause
injury when the supplemental side air­
bag deploys.
- Never carry any objects or pets in the
deployment space between them and
the airbags or allow children or other passengers to travel in this position .
- Always use the built -in coat hooks only
for lightweight clothing . Never leave any
heavy or sharp-edged objects in the
pockets that may interfere with side air­
bag deployment and can cause personal
injury in an accident.
- Always prevent the side airbags from be­
ing damaged by heavy objects knocking
against or hitting the sides of the seat­
backs.
- The airbag system can only be triggered
once. If the airbag has been triggered,
the system must be replaced by an au­
thorized Audi dealership.
- Damage (cracks, deep scratches etc .) to
the original seat covers or to the seam in
the area of the side airbag module must always be repaired immediately by an au­
thorized Audi dealer .
- If children are seated improperly, their
risk of injury increases in the case of an
accident
~ page 163, Child Safety.
- Never attempt to modify any compo­
nents of the airbag system in any way .
- In a side collision, side airbags will not
function properly if sensors cannot cor­ rectly measure increasing air pressure in-
side the doors when air escapes through .,.. •

- Only use factory-installed sun shades or,
if shades installed after the vehicle
leaves the factory, use only genuine Audi
sun shades.
- Never swing the sun viso rs ove r to the
side windows if things such as pens, ga­
rage door openers, hands-free speake rs,
etc. are a ttached to the sun visors. They
cou ld come loose and cause se rious in­
