- Never place or use any electrical device
(suc h as a laptop, CD player, electronic
games dev ice, power inverte r or seat heater
for child seats) on the front passenger seat
if the devi ce is conne cted to the 12-volt
socket o r the cigarette lighter socket. Such
devices can in fluence the capacitance regis ­
tered by the capacitive 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
passenge r seat and the child restraint man­
ufact urer 's instructions require the use of a
towel, foam cushion or something else to
properly pos ition the ch ild restraint, make
certain tha t the

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 airbag system from work­
ing properly and may, for instance, deact i­
vate the passenger frontal airbag. If this
happens, the
PASSENGER AIR BAG OFF
light will come on and stay on togethe r with
the a irbag indicator light
II (USA models)/
El (Canada models) in the instrument clus­
ter.
- If liquid is poo led on the seat, bu t has not
soa ked in, this may also keep the airbag sys­
tem from wo rking pro perly and ca use the
passenge r frontal airb ag to be enabled
(tu rned on), even though the re is a properly
Airbag syste m
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 passenger fronta l airbag is turned on,
the
PASSENGER AIR BAG OFF light will
turn off.
How the Advanced Airbag System
components work together
T he front Advance d Airb ag Sys tem and the side
airbags supp lement the protection offered by the
front t hree-point safety be lts and the adjustable

More important things to know about front
airbags
Fig. 153 I nf lated front airbags
Safety belts are important to help keep front
seat occupants in the proper seated position so
that airbags can unfold properly and provide sup­ plemental 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 airbag deploys, fine dust is released.
This is normal and is not caused by a fire in the
vehicle. This dust is made up mostly of a powder
used to lubricate the airbags as they deploy. It
could irritate skin.
It is important to remember that while the sup ­
plemental airbag system is designed to reduce
the likelihood of serious injuries, other injuries,
for example swelling, bruising and minor abra -
152
sions, 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 belt s only in some frontal collisions
in which the vehicle deceleration is high enough
to deploy the airbags .
Front airbags will not deploy :
-if the ignition is switched off when a crash oc-
curs,
-in side co llisions,
- in rear-end collisions,
- in rollovers,
- when the crash deceleration measured by the
airbag system is less than the minimum thresh­
old needed for airbag deployment as reg iste red
by the electron ic cont rol un it.
The front passenger airbag also will not
deploy:
- when the front passenger seat is not occupied,
- when the e lectrical capacitance measured by
the capacitive passenger detection system for
the front passenger seat indicat es that the pas­
senger side frontal a irbag must be switched off
by the electronic control unit (the
PASSENGER
AIR BAG OFF
light r=;, page 154 and how they
work comes on and stays on).
A WARNING
, -
Sitting in the wrong position can increase the
risk of serious injury in crashes.
-To reduce the risk of injury when the airbags
inflate, the driver and passengers must al­
ways sit in an upright posit ion, must not
lean aga inst or place any part of their body
too close to the area where the airbags are
located.
- Occupants who are unbe lted, out of posit ion
or too close to the airbag can be serious ly
inju red by an airbag as it unfolds with g reat
force in the blink of an eye

" N .... 0 0 \,;J ' 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
"AIRBAG" 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-
-
Airbag system
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.

light will stay on.
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-
-
Airbag system
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
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

¢ page 152, More important things to know
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 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 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
so ¢ page 134, Gener­
al information.
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 collision.
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 designed to re­
duce the likelihood of serious injuries, other inju­
ries, for example, swelling, bruising and minor
abrasions 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
Airbag system
- 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 malfunction (warning/
indicator light is on)
¢ page 16 .
.&_ WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
the proper seating position
¢page 152.
- If the airbag indicator light ¢page 16
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 inflate when it should.
How knee airbags work
App lies to: vehicles wi th knee airbags
The risk of injury to the leg area can be reduced
by fully inflated knee airbags.
Fig. 156 Inflated airbags protecting in a fro ntal coll is ion
The knee airbag system has been designed so
that the airbags for the driver and front passen­
ger deploy in certain but not all frontal collisions .
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 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. 153. .,.
