switched on and turns the airbag indicator light
on when a malfunction in the one of the system
components is detected
c::> page 155. Because
the front passenger seat contains important
parts of the Advanced Airbag System, you must
take care to prevent it from being damaged .
Damage to the seat may prevent the Advanced
Airbag System for the front passenger seat from
doing its job in a crash.
The front Advanced Airbag System consists
of the following:
-Crash sensors in the front of the vehicle that
measure vehicle acceleration/ deceleration to
provide information to the Advanced Airbag
System about the severity of the crash.
- An electronic control unit, with integrated
crash sensors for front and side impacts. The
control unit "decides" whether to fire the front
airbags based on the information received from
the crash sensors. The control unit also "de­
cides" whether the safety belt pretensioners
should be activated .
- An Advanced Airbag with gas generator for the
driver inside the steering wheel hub.
- An Advanced Airbag with gas generator inside
the instrument panel for the front passenger.
- A capacitive passenger detection system under­
neath the front passenger seat cover. This sys­
tem measures the electrical capacitance of the person in the seat. The information registered
is sent continuously to the electronic control
unit to regulate deployment of the front Ad­
vanced Airbag on the passenger side .
- An airbag monitoring system and indicator
light in the instrument cluster
c::> page 155 .
-A sensor in each front seat registers the dis­
tance between the respective seat and the
steering wheel or instrument panel. The infor­
mation registered is sent continuously to the
electronic control unit to regulate deployment
of the front Adv a need Airbags.
- The
PASSENGER AIR BAG OFF light comes on
and stays on in the center of the instrument
panel
c::> page 188 and tells you when the front
Advanced Airbag on the passenger side has been turned off.
Airbag system
-A sensor in the safety belt latch for the driver
and for the front seat passenger that senses
whether that safety belt is latched or not and
transmits this information to the electronic control unit.
A WARNING ,.__
Damage to the front passenger seat can pre­
vent the front airbag from working properly .
- Improper repair or disassembly of the front
passenger and driver seat will prevent the
Advanced Airbag System from functioning properly.
- Repairs to the front passenger seat must be
performed by qualified and properly trained
workshop personnel.
- Never remove the front passenger or driver
seat from the vehicle .
- Never remove the upholstery from the front
passenger seat.
- Never disassemble or remove parts from the
seat or disconnect wires from it.
- Never carry sharp objects in your pockets or
put them on the seat. The capacitive pas­
senger detection mat in the front passenger
seat will not function properly if it is punc­
tured.
- Never carry things on your lap or carry ob­
jects on the front passenger seat. Such ob­
jects can influence the capacitance regis­
tered by the capacitive passenger detection
system, so that incorrect information is pro­
vided to the airbag control unit.
- Never store items under the front passenger
seat. Parts of the Advanced Airbag System
under the passenger seat could be dam­
aged, preventing them and the airbag sys­
tem from working properly.
- Never place seat covers or replacement up­
holstery that have not been specifically ap­
proved by Audi on the front seats.
- Seat covers can prevent the Advanced Air­
bag System from recognizing child re­
straints or occupants on the front passenger
seat and prevent the side airbag in the seat
backrest from deploying properly .
151

Airbag syste m
-If a seat heater has been retrofitted or oth­
erwise added to the front passenger seat,
never install any child restraint system on
this seat .
- Never use cushions, pillows, blankets, or
similar items on the front passenger seat.
The additional layers prevent the capacitive
passenger detection system from accurately
measuring the capac itance of the ch ild safe­
ty seat and/or the person on the seat and
th us keep the Advanced Airbag System from
working properly .
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat heater
for child seats) on the front passenger seat if the device is connected to the 12-volt
socket or the cigarette lighter socket. Such devices can influence the capacitance reg is­
tered by the capac itive passenger detection
system, so that incorrect information is pro­
vided to the airbag control unit.
- If you must use a child restraint on the front passenger seat and the child restraint man­
ufacturer's instructions require the use of a
towel, foam cushion or something else to properly position the ch ild rest raint, make
certain that the
PASSENGER AIR BAG OFF
light comes on and stays on whenever the
child restraint is insta lled on the front pas­
senger seat.
- If the
PASSENGER AIR BAG OFF light does
not come on and stay on, immediately in­
stall child restraint in a rear seating position
and have the airbag system inspected by
your Audi dealer.
A WARNING
If the front passenger seat gets wet, dry it im­
mediately.
- If liquid soaks into the front passenger seat,
this can keep the a irbag system from work­
ing properly and may, for instance, deact i­
vate the passenger frontal airbag. If this
happens, the
PASSENGER AIR BAG OFF
ligh t will come on and stay on togethe r with
the airbag indicator light
II (USA models) I
152
E,I (Canada mode ls) in the instr ument clus­
ter.
- If liq uid is pooled on the seat, but has not
soaked in, th is may also keep the airbag sys­
tem from working proper ly and cause the
passenger frontal airbag to be enabled
(turned on), even though there is a p roperly
installed child restraint system on the seat.
Wet towels or other wet things on the seat
cushion can have the same effect. If the
front p assenger front al airbag is turned on,
the
PASSENGER AIR BAG OFF light will go
out .
How the Advanced Airbag System
components work together
The front Advanced A irbag System and the side
airbags supp lement the protection offered by the
front th ree-point safety belts with pretens ioners
and load lim ite rs and the adj ustab le head re­
straints* to help reduce the risk of i njury in a
wide range of accident and cras h situations. Be
s ur e to read the impo rtant informat ion about
sa fety and heed the WARNINGS in this chapter.
Deployment of the Advanced A irbag System and
the activa tion of the safety belt pretens ioners de­
pend on the dece lera tion measured by the crash
senso rs and registered by the electronic contro l
unit . Crash severity depends on speed and decel­
eration as well as the mass and stiffness of the
vehicle or object involved in the crash.
On the passenger side, regard less o f safety be lt
use, the front passenger frontal airbag will be
turned off if the e lectrica l capacitance measured
by the capacitive passenger detection system on
the front passenger seat is less than the amount
programmed in t he e lectronic contro l unit . The
front passenger frontal a irbag w ill also be tur ned
off if the capacitance measured by the system for
t h e front passenger seat equals that of an infant
of about o ne yea r of age in one o f the ch ild sea ts
that was used to certify the Advanced Airbag Sys­
tem under Federa l Motor Vehicle Safety Standard
208. The
PASSENGER AIR BAG OFF light comes
on and stays on to tell you when the front Ad­
vanced Airbag System on the passenger side has been turned off

A WARNING
To reduce the risk of injury when an a irbag in­
flates, always wear safety belts properly.
- If you are unrestrained, lean ing forward, sit­
t in g s ideways or out of pos ition in anyway,
your risk of injury is much higher.
- You will also receive serious injur ies and
could even be killed if you are up aga inst the
airbag or too close to it when it inflates -
even with an Advanced Airbag¢

More important things to know about front
airbags
F ig. 139 Inflated front airbags
Safety belts are important to help keep front
seat occupants in the p roper seated position so
that airbags can unfold properly and provide sup­
p lemental protection in a frontal collision.
The front airbags are designed to provide addi­
tional protection for the chest and face of the
driver and the front seat passenger when:
- safety belts are worn properly,
- the seats have been positioned so that the oc-
cupant is properly seated as far as possible
from the airbag,
- and for adjustable head restraints: the head re-
straints have been properly adjusted.
Because airbags inflate in the blink of an eye with
great force, things you have on your lap or have placed on the seat could become dangerous pro­
jectiles , and be pushed into you if the airbag in­
flates .
When an a irbag deploys, fine dust is released .
This is normal and is not caused by a fire in the
veh icle. This dust is made up mostly of a powder
Airbag system
used to lubricate the airbags as they deploy. It
could irritate skin.
It is important to remember that while the sup­
plementa l airbag system is designed to red uce
the likelihood of serious injuries, other injuries,
for example swelling, bruising and minor abra­
s ions, can also happen when airbags inflate. Air­
bags do not protect the arms or the lower parts
of the body. Front airbags supplement the three­
point safety belts on ly in some frontal collisions
in which the vehicle deceleration is high e nough
to deploy the airbags .
Front airbags will not deploy:
- if the ignition is switched off when a crash oc-
curs,
- in side collisions,
- in rear-end collisions,
- in rollovers,
- when the crash deceleration measured by the
airbag system is less than the m inimum thresh­
old needed for airbag deployment as registe red
by the electronic control unit.
The front passenger airbag also will not
deploy:
- when the front passenger seat is not occupied,
- when the electr ica l capacitance measured by
the capacitive passenger detection system for
the front passenger seat indicates that the pas­
senger side frontal a irbag must be switched off
by the electronic control unit (the
PASSENGER
AIR BAG OFF
light¢ page 155 and how they
work comes on and stays on).
A WARNING
-Sitt ing in the wrong position can increase the
risk of ser ious injury in crashes.
- To reduce the risk of injury when the airbags
inflate, the drive r and passengers must al­
ways sit in an up right position, must not
lea n against or place any part of their body
too close to the area where the airbags are
located .
- Occupants who are unbelted, out of position
or too close to the airbag can be seriously
injured by an airbag as it unfolds with great
force in the blink of an eye¢

Airbag system
A WARNING
A child in a rearward-facing child seat instal­
led on the front passenger seat will be seri ­
ously injured and can be killed if the front air­
bag inflates - even with an Advanced Airbag
System.
- The inflating airbag will hit the child seat or
infant carrier with great force and will
smash the child seat and child against the backrest, center armrest, door or roof.
- Always install rear-facing child seats on the
rear seat.
- If you must install a rearward facing child
seat on the front passenger seat because of exceptional circumstances and the
PASSEN­
GER AIR BAG OFF
light does not come on
and stay on, immediately install the rear­
facing child seat in a rear seating position
and have the airbag system inspected by
your Audi dealer.
A WARNING
Objects between you and the airbag will in­
crease the risk of injury in a crash by interfer­
ing with the way the airbag unfolds or by be­
ing pushed into you as the airbag inflates .
- Never hold things in your hands or on your
lap when the vehicle is in use .
- Never transport items on or in the area of
the front passenger seat . Objects could
move into the area of the front airbags dur­
ing braking or other sudden maneuvers and
become dangerous projectiles that can
cause serious personal injury if the airbags
inflate.
- Never place or attach accessories or other
objects (such as cup holders, telephone
brackets , large, heavy or bulky objects) on
the doors, over or near the area marked "A IRBAG" on the steering wheel, instru­
ment panel, seat backrests or between
those areas and yourself. These objects
could cause injury in a crash, especially
when the airbags inflate .
- Never recline the front passenger 's seat to
transport objects. Items can also move into
the area of the side airbag or the front air-
154
-
bag during braking or in a sudden maneu­
ver. Objects near the airbags can become
projectiles and cause injury, particularly
when the seat is reclined.
- Never place or transport objects on the
front passenger seat. Objects on the front passenger seat could cause the capacitive
sensor in the seat to signal to airbag system
that the seat is occupied by a person when it
in fact is not , or that the person on the seat
is heavier than he or she actually is. The
change in electric capacitance because of
such objects can cause the passenger front
airbag to be turned on when it should be
off, or can cause the airbag to work in a way
that is different from the way it would have
worked without objects on the seat.
- Always make sure that there is nothing on
the front passenger seat that will cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that
the seat is occupied by a person when it is not, or to signal that it is occupied by some­
one who is heavier than the person actually
sitting on the seat. The presence of an ob­
ject could cause the passenger front airbag to be turned on when it should be off, or
could cause the airbag to work in a way that is different from the way it would have
worked without the object on the seat.
A WARNING
The fine dust created when airbags deploy can
cause breathing problems for people with a history of asthma or other breathing condi­
tions .
- To reduce the risk of breathing problems,
those with asthma or other respiratory con­
ditions should get fresh air right away by
getting out of the vehicle or opening win­
dows or doors .
- If you are in a collision in which airbags de­
ploy , wash your hands and face with mild
soap and water before eating.
- Be careful not to get the dust into your eyes,
or into any cuts or scratches.
- If the residue should get into your eyes,
flush them with water .

veh icle can damage a part of an airbag system
and p revent that system from working properly
in a co llision .
There are some important things you have to
know to make sure that the effectiveness of the
system wi ll not be impaired and that discarded
components do not cause injury or poll ute the
env ironment.

-
p loying when needed or deploy ing an a irbag
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 s uch as c up ho lders
or telephone mountings to the surfaces cov­
ering the a irbag un its .
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one mois­
tened w ith plain water. Solvents or cleaners
could damage the airbag cover or change
the st iffness o r streng th of the material so
that the airbag cannot deploy and p rotect
prope rly.
- Never repair, ad just, or change any parts of
the airbag system.
- All work on the steering wheel, inst rument
panel, front seats or e lectr ica l system ( in­
cluding the installation of a udio eq uipment,
cellular tele phones and C B radios, etc.)
m ust be perfo rmed by a qu alified techn ician
who has the training and specia l equipment
necessary.
- For any work on the airbag system, we
strong ly recommend that you see your au­
thorized A udi dealer or qualified wo rkshop.
- Never modify the front b umper or parts of
the vehicle body.
- Always make sure that the side a irbag can
inflate w ithout interference:
- Never install seat covers or replacement
upholstery ove r the front seatbacks that
have not been specifically approved by
A udi .
- Never use addi tional seat c ushions that
cover the areas where the side airbags in­
flate .
- Damage to the orig inal seat cove rs or to
the seam in the area of the s ide airbag
module mus t always be repaired immedi­
ate ly by an autho riz e d Au di dealer .
- The a irbag sys tem can deploy only once. Af­

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that t he Advanced Airbag System
pe rforms in a crash. For examp le, using tire-r im
comb inat ions no t approved by Audi, lowering the
ve hicle, changing the s tiffness of the suspens ion,
includ ing the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
e lectronic contro l unit . Some suspens ion 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 dep loy if
the changes had no t been made. Other kinds of
Airb ag sys tem
changes may red uce the force levels measured by
the sensors and prevent the airbag from deploy­
i ng when it sho uld.
A WARNING
=
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance a nd in­
crease the risk of serious personal injury in a
crash.
- Never install suspension components that do not have the same performance charac­
ter istics as the components origina lly instal­
led on you r vehi cle.
- 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 supplemen­
tal protection to properly restrained front seat
occupants .
Fig. 14 1 Driver 's k nee a irbag
The driver knee airbag is in the instrument panel
underneath the s teer ing whee l
~fig. 141, the
airbag fo r the passenger is at abou t the same
heig ht in the i nstr ume nt p ane l underneath the
glove compa rtment.
The knee airbag offers add itiona l protection to
t h e d river's and passenge r's knees and uppe r and
l ower thigh areas a nd supplements the p rotec­
t ion prov ided by the safety bel ts .
If the front airbags deploy, the knee a irbags also
deploy in frontal coll is ions when the deploymen t

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 prov ide supplemental protect ion .
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
always wear your safety belt, not just because
the law requires you to do soc::>
page 135, Gener­
al notes .
Remember too, airbags will deploy only once and
only in certain kinds of accidents -your safety
belts are always there to offer protect ion 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 correct ly.
It is important to remember that whi le the sup­
p lemental knee airbag system is designed to re­
duce the likelihood of serious injuries, other inju­
ries, for example, swelling, bruising and minor
abras ions and friction burns can also occur when
an airbag inflates .
The knee airbag system basically consists of:
-The electronic control module
- Two inflatab le 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
160
- in frontal collisions when the deceleration
measured by the contro l unit is too low
- in side collisions
- in rear-end collisions
- in rollovers
- in the event of a system malfunction (warning/
ind icator light is on)
<=:>page 17.
.&_ WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
th e proper seating position
r:!> page 153 .
-If the airbag indicator light c::> page 17
comes when the vehicle is being used, have
the system inspected immediately by your
authorized Audi dealer.
It is possible that
the airbag will inflate when it is not sup ­
posed to, or will not inf late when it should.
How knee airbags work
Applies to: vehicles with knee airbags
The risk of injury to the leg area can be reduced
by fully inflated knee airbags.
Fig. 142 Inflated a irbags protect ing in a frontal coll is io n
The knee airbag system has been designed so
that the airbags for the driver and front passen­
ger dep loy in certain bu t not all fronta l co llisions.
If the front airbags deploy, the knee airbags also
deploy in frontal coll isions when the deployment
threshold stored in the control unit is met.
When the system deploys, the airbags f ill with a
compressed propellant gas, and inf late between
the lower part of the instrument panel and the
driver and the lower part of the instrument panel
and the front passenger c::>
