the vehicle. This dust is made up most ly of a
powder used to lubricate the airbags as they
deploy . It cou ld irritate skin .
It is importan t to remember that while the
supplemental airbag system is designed to re
duce the likelihood of serious injuries , other
in ju ries, for example swell ing, bruising and
minor abrasions, can also happen when air
bags inflate. Airbags do not protect the arms
or the lower parts of the body . Front airbags
supplement the three-poi nt safety belts only
i n some frontal collisions in which the vehicle
decelerat ion is high enough to deploy the air
bags.
Front airbags will not deploy:
- if the ignit ion is switched off when a crash
occurs,
- in s ide collisions,
- in rear-end collisions,
- in ro llovers,
- when the crash deceleration measured by
the airbag system is less than the minimum
threshold needed for airbag deployment as
registered by the electronic control unit.
Th e front pa sseng er airbag al so will not
d e plo y:
-when the front passenger seat is not occu
pied,
- when the electrical capacitance measured by
the capacitive passenger detect ion system
for the front passenger seat indicates that
the passenger side frontal airbag must be
switched off by the electronic control unit (the
P ASSENGER AIR BAG OFF light
¢ page 155 and how they wo rk comes on
and stays on).
A WARNING
Sitting in the wrong position can increase
the risk of serious injury in crashes .
- To reduce the r isk o f injury when the air
bags inflate, the driver and passengers
must a lways sit in an upright position,
must not lean against or place any part
A irbag system 153
of their body too close to the area where
the airbags are located.
- Occupants who are unbelted, out of posi
tion or too close to the airbag can be se
riously injured by an airbag as it unfolds
with great force in the blink of an eye
¢page 144.
A WARNING
A child in a rearward-fac ing ch ild seat in
stalled on the front passenger seat will be
se riously injured and can be killed if the
front airbag inflates - even w ith an Ad
vanced A irbag System.
- The inflating airbag will h it the ch ild seat
or infant carrier with great fo rce and will
smash the child seat and child against
the backrest, center armrest, doo r or
roof.
- Always install rear -facing chi ld seats on
the rear seat.
- If you must install a rearward fac ing
child seat on the front passenger seat
because of exceptional circumstances
and the PASS ENG ER AIR BAG OFF light
does not come on and stay on, immed i
ately insta ll the rear-facing child seat in a
rea r seat ing pos ition and have the airbag
system inspected by your Audi dealer .
A WARNING
Objects between you and the airbag will
increase the r isk of injury in a crash by in
terfering with the way the ai rbag unfolds
or by be ing p ushed into you as the airbag
inflates.
- Neve r hold things in yo ur hands o r on
your lap when the veh icle is in use.
- Never transpo rt items on or in the a rea
of the front passenger seat. Objects
co uld move into the area of the front air
bags during braking or other sudden ma
neuvers and become dangero us projec
tiles that can cause ser ious personal in
jury if the a irbags inf late.

- Never place or attach accessories or o th
er objects (such as cup holders, tele
phone brackets, large, heavy or bulky ob
jects) on the doors, over or near the area marked "AIRBAG" on the stee ring wheel,
instrument panel, seat backrests or be
tween those a reas and yourself. These
objects co uld cause injury in a crash, es
pecially when the airbags inflate .
- Never recline the front passenger's seat
to transport objec ts. Items can also
move into the area o f the side airbag or
the front airbag during braking or in a sudden maneuver . Objects near the air
bags can become project iles and cause
injury, part icularly when the seat is re
cl ined .
- Never place or transport ob jects on the
front passenger seat. Objects on the
front passenger seat could cause the ca pacitive senso r in the seat to s ignal to
airbag system that the seat is occupied
by a person whe n it in fa ct is not, o r that
the person on the se at is heavie r than he
or she actually is. The change in electric
capacitance because of such objects can
cause the passenger front airbag to be
t u rned on when it sho uld be
off, or can
cause the airbag to work in a way that is
different from the way it wou ld have
wor ked w ithout ob jects on the seat .
- Always make sure that there is nothing
on the front passenger seat that will
cause the capacitive passenge r detection
system in the s eat to s ignal to the A irbag
System that the seat is occupied by a
person when it is not, or to signa l th at it
is occupied by someone who is heavier
than the pe rson actually s itting on the

off, or co uld
cause the airbag to work in a way t hat is
different from the way it wou ld have
worked w ithout the object on the seat.
A WARNING
The fine dust created when airbags deploy
ca n cause breathing p rob lems for people
with a history of asthma or ot her breath
i ng cond itions .
- To reduce the risk of breath ing problems ,
those wi th asthma o r othe r respiratory
conditions s hou ld get fresh air right
away by getting o ut of th e veh icle or

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
& Maintenance book
let under
AIRBAG REPLACEMENT RE
CORD.

Other things that can affect Advanced
Airbag performance
C hanging the vehicle's suspension system can
ch ange the way that the Advanced A irbag Sys
tem pe rforms in a crash. For example, us ing
tire-rim combinations not app rove d by Audi,
lowe ring the vehicle, changing the stiffness of
the suspension, incl uding the springs, suspen
sion struts, shock absorbers etc. can change
the forces that are measured by the a irbag
se nsors and sent to the electron ic control
un it . Some suspension changes can, for exam
p le, increase the force levels measured by the
se nsors and make the airbag system deploy in
crashes i n w hich it would not dep loy if the
ch an ges had not been made. Ot her kinds of
cha nges may reduce the force levels meas
ured by the sensors and prevent the airbag
from deploying when it shou ld.
The senso rs in the safety belt buckle fo r th e
d river and front passenger seat tell the elec
tronic control module if the safety belt is
l atched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high-
A irba g sy stem 159
er rate of vehicle deceleration than i f the safe
ty belt is not being used. Therefore, in a par
ticu lar collis ion, it is possible t hat an airbag
will not deploy at a seating pos ition where the
safety belt is be ing used but w ill inflate at the
position w here the safety belt is not be ing
used. It is impo rtant that noth ing interfere
with the safety be lt b uckles so that the sen
sors can send the cor rec t info rmation abou t
sa fe ty belt use to the elec tronic con trol un it.
_&. WARNING ~-
Changing the vehicle's suspension includ-
ing use of unapprove d tire -rim combina
tions can change Advanced Airbag per
formance and increase the risk o f serious
personal injury in a crash.
- Never install s uspension components
that do not have the same performance
characteristics as the components origi
na lly installed on your vehicle .
- Never use tire-rim combinations that
have not been approved by Audi.
Knee airbags
Description of knee airbags
Appl ies to vehicles: wi th knee airbags
The knee airbag system can provide supple
mental prot ection to properly r estrain ed
front seat occupants.
Fi g. 14 8 Drive r's airbag
T he driver knee airbag is i n the instrument
panel underneath the steering wheel
i=> fig . 148, the airbag for the passenger is at
about the same height in the instrument pan-
el underneath the glove compartment . ..,_
160 Airbag sys te m
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
wo rk p roperly when the vehicle a ccele ra
tion in a side col lision is high enough to

How knee airbags work
Applies to vehicles: with knee airb ags
The risk of injury to the leg area can be re
duced by fully inflated knee airbags.
Fig. 149 Inflated airbags protecting in a frontal coll i
sio n
The knee airbag system has been designed so
that the airbags for the driver and front pas
senger deploy in certain but not all frontal
collisions .
If the front airbags deploy, the knee airbags
also deploy in frontal collisions when the de ployment 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 lower part of the instrument panel and the front passenger¢
page 152,
fig. 146.
Although they are not a soft pillow, they can
"cush ion" the impact and in this way they can
help to reduce the risk of injury to the lower
extremities.
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 with a great deal of force and it is im
portant for occupant safety that nothing
should be in their way when they deploy.
Fully inflated airbags in combination with
properly worn safety belts slow down and lim
it the occupant's forward movement and help
to reduce the risk of injury.
Airbag system 161
Important safety instructions on the
knee airbag system
Applies to vehicles: wit h knee airbags
Airbags are only supplemental restraints . Al
ways 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 provide supplemental protection.
_&. WARNING .. -
An inflating knee airbag can cause serious injury. Wearing safety belts incorrectly and
imprope r seating positions increase the
risk of serious personal injury and death
whenever a vehicle is being used.
- The knee airbag system cannot protect
you properly if you a re seated too close
to any of the airbag locations. When ad
justing their seat positions, it is impor
tant that both the driver and the front passenger keep their upper bodies and
knees at the following minimum safe
distances:
- at least 10 inches (25 cm) between the
chest and the steering wheel/instru
ment 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 side, or if the seat is improperly positioned and you are
not wearing your safety belt . The risk in
creases even more should the airbag de
ploy.
- Always make sure that the knee airbag
can inflate without interference. Objects
between you and the airbag can increase
the risk of injury in an accident by inter
fering with the way the airbag deploys or
by being pushed into you as the airbag
deploys.
- Never let anybody, especially children
or animals ride in the footwell in front
