Airbag system
A WARNING
A child in a rearward-facing child safety seat
installed on the front passenger seat will be
seriously injured and can be killed if the front
airbag inflates - even with an Advanced Airbag
System.
- The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the child safety seat and child against the backrest, center armrest, door
or roof.
-Always install rear-facing child safety seats on the rear seat.
- If you must install a rearward facing child
safety seat on the front passenger seat be cause of exceptional circumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immediately install
the rear -facing child safety 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
278
the area of the side airbag or the front air
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.

Repair , care and disposal of the airbags
Parts of the airbag system are installed at many
d ifferent places on your Aud i. Install ing, remov
ing, servic ing or repa iring a part in an area of the
veh icle can damage a pa rt 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 effectiveness of the
system w ill not be impaired and that discarded
components do not cause injury or pollute the
environment .
,& WARNING
Improper care, servicing and repair proce
dures can increase the r isk of personal injury
and death by preventing an airbag from de
ploying when needed or deploying an airbag
unexpectedly:
282
- 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 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 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, inst rument
panel, front seats or e lectr ica l system ( in
cluding the instal lation of a udio eq uipment,
cellular telephones and CB radios, etc.)
m ust be performed by a qualified technician
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 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 specif ica lly approved by
A udi.
- Never use additional 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 repai red immedi
ate ly by an authorized Audi dealer.
- The a irbag sys tem can deploy on ly once. Af
ter an airbag has been deployed, it m ust be
replaced with new replacement parts de
signed and approved especia lly for your
Audi model version . Replacement of com
plete airbag systems or airbag components
must be performed by qua lified workshops
only . Make sure that any airbag service

action is entered in your Audi Warranty &
Maintenance booklet under
AIRBAG RE
PLACEMENT RECORD.
- Applies to plug-in hybrid* vehicles: In the
event of a co llision where the a irbags de
ploy, the electrical connection to the high
voltage battery is automatically disconnect
ed. This prevents a short c ircuit.

rate. When the veh icle or parts of the re
straint system incl uding airbag modules and
safety belts with pre tensioners are scrapped,
all applicable laws and regulations must be
observed. Your authorized Audi dealer is fa
miliar with these requirements and we recom
mend that you have your dealer perform this
service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys tem
performs in a crash. For examp le, using tire-r im
combinations not approved by Audi, lowering the
vehicle, changing the stiffness of the suspension, including the springs , suspension struts, shock
absorbers etc. can change the forces that are
measured by the airbag sensors and sent to the
electronic control 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
t he changes had no t been made. Other kinds of
changes may reduce the force levels meas ured by
the sensors and prevent the airbag from deploy ing when it should.
.&_ WARNING
Changing the vehicle 's s uspension incl uding
use of unapproved tire-rim combinations can
change Advanced A irbag performance and in-
Airb ag sys tem
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 originally instal
led on your vehicle.
- Never use tire-rim combinations that have
not been approved by Audi.
Knee airbags
Description of knee airbags

Airbag syste m
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overa ll 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 258, Gener
al notes.
Remember too, airbags will deploy only once and
only in certain k inds of accidents
-your safety
be lts are always there to offer protection in those
accidents in wh ich airbags a re not supposed to
deploy or when they have already deployed, for
examp le when your vehicle str ikes or is struck by
another after the first collision .
This is just one of the reasons why an airbag is
not a substi tute for the safety belt. The a irbag
system works most effectively when used with
the safety belts. Therefore, a lways wear your
safety belts correct ly.
It is important to remember that whi le the sup

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.
F ig . 246 Inflated a irbags protec ting in a fro nta l co llis io n
The knee airbag system has been designed so
that the airbags for the driver and front passen
ger dep loy in certain but not all frontal collisions .
If the front airbags deploy, the knee airbags also
deploy in frontal collisions when the dep loyment
threshold stored in the control unit is met.
When the system deploys, the a irbags 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
