Airbag system
Front airbags
Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat occu­
pants.
Fig. 161 location of driver airbag: in steering wheel
Fig. 162 location of front passenger's airbag: in the in­
strument panel
Your vehicle is equipped with an "Advanced Air­
bag System" in compliance with Un ited States
Federal Motor Vehicle Safety Standard
(FMVSS) 208, as well as Canada Motor Vehicle
Safety Standard (CMVSS) 208 as applicable at
the time your vehicle was manufactured.
The airbag for the driver is in the steer ing whee l
hub
~ fig. 161 and the airbag for the front pas­
senger is in the instrument panel
~fig. 162. The
general location of the airbags is marked "AIR­
BAG" .
There is a lot you need to know about the airbags
in your vehicle. We urge you to read th e detailed
information about airbags, safety belts and child
safety in this and the other chapters that make
up the owner's literature. Please be sure to heed
the WARNINGS - they are extremely important
198
for your safety and the safety of your passengers,
especially infants and small children.
A WARNING -
Never rely on airbags alone for protection.
- Even when they deploy, airbags provide only
supplemental protection.
- Airbag work most effectively when used with proper ly worn safety belts.
- Therefore, always wear your safety be lts and
make sure that everybody in your veh icle is
properly restrained.
- Always hold the steering wheel with both hands on the outside of the steering wheel
rim at the 9:00 o'clock and 3:00 o'clock po­
sitions to help reduce the risk of personal in­
jury if the driver's airbag inflates.
- Never hold the steering wheel at the 12
o'clock position or with your hands any­
where inside the steering wheel or on the
steering wheel hub. Holding the steering
wheel the wrong way increases the risk of
severe injury to the arms, hands, and head if
the dr iver airbag deploys .
.&_ WARNING
Objects between you and the airbag will in­
crease the r isk of injury in a crash by interfer­
ing with the way the airbag unfolds and/or by
being pushed into you as the airbag inflates.
-Always make sure nothing is in the front air-
bag deployment zone that cou ld be struck
by the airbag when it inflates.
-
- Objects in the zone of a deploying airbag
can become projectiles when the airbag de­
ploys and cause serious personal injury.
- Never hold things in your hands or on your
lap when the vehicle is in use.
- Never p lace accessories or other objects
(such as cup holders, telephone brackets,
note pads, navigation systems, or things
that are large, heavy, or bulky) on the doors;
never attach then to the doors or the wind­
shield; never place them over or near or at­
tach them to the area marked ,,AIRBAG" on the steering wheel, instrument panel or the
.,..

Airbag syste m
Front airbag s will not d eploy:
- i f the ig nition is switched off whe n a cr ash oc-
cu rs,
- i n s ide collisions,
- in rear-end collisions,
- in rollovers,
- when the crash decelerat ion measured by the
airbag system is less than the minimum thresh ­
old needed for airbag deployment as registered
by the electronic contro l unit .
The front p assenger airb ag will also not
deploy:
- when the front passenger seat is not occup ied,
- whe n the electrical capac itance measured by
the capacitive passenger detect ion system for
the front passenger seat indicates that the pas­
senger side frontal airbag must be switched off
by the electronic contro l unit (the
PASSENGER
A IR BAG
OFF ~; ligh t~ page 206 and how
they work comes on and stays on) .
.&_ 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 position, must not
lean against or p lace 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 a irbag can be seriously
injured by an airbag as it unfolds with great
force in the b link of an
eye <=;> page 195.
.&_ WARNING
A child in a rearward-facing chi ld seat insta l­
led on the front passenger seat will be ser i­
ously inju red and can be killed if the front air­
bag inflates
-even with an Advanced Airbag
System.
- T he inflating a irbag w ill hit the child seat or
infant carrier with great force and will
smash the chi ld seat and child against the
backrest, center armrest, door or roof.

-
- Never install a rearward facing chi ld safety
seat on the front passenger seat unless the
PAS SEN GER AIR B AG OFF ~; light comes
on and stays on . If the
PA SSENGER AIR
BAG
OFF ~; light does not come on and stay
on, the inflat ing airbag will hit the chi ld
safety seat or infant carrie r wi th great force
and will smash the child safety seat and
child against the bac krest, door or roof .
Have the airbag system inspected immedi­
ately by your authorized Audi dealer .
.&_ WARNING
Objects between you and the airbag will in­
crease the r isk 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 veh icle 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 maneuver and
become dangerous projectiles that can
cause serious persona l injury if the airbags
inflate.
- Never place or attach accesso ries o r othe r
objects (such as cup holders, telephone brackets, large, heavy or bulky ob jects) on
the doo rs, ove r or near the area ma rked
"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 a irbags inflate.
- Never recl ine the front passenger's seat to
transport objects. Items can also move into
the area of the side a irbag or the front air­
bag during brak ing or in a sudden maneu­
ver. Objects near the airbags can become projecti les and cause injury, part icularly
when the seat is reclined.
- Never p lace or t ransport objects on the
-
front passenger seat. Objects on the front
passenger seat could ca use the capaci tive
sensor in the seat to signal to airbag system
that the seat is occ upied by a person when it

authorized Aud i dealer. It is possible that
the a irbag will inflate when it is not sup­
posed to, or will not inflate when it should.
A WARNING
If the front airbag inflates, a child without a
child restra int, or in a rearward-facing child
safety seat, or in a forward-facing child re­
st raint that has not been p roperly installed
w ill be seriously injured and can be killed.
- If you must install a rearward-fac ing child
seat on the front passenger seat because of
exceptional c ircumstances and the

Repair , care and disposal of the airbags
Parts of the a irbag system are installed at many
d ifferent p laces on your Aud i. Insta lling, remov-
208
ing, servicing or repair ing a part in an area of the
vehicle can damage a part of an airbag system
and prevent that system from work ing properly
i n a coll is ion.
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
du res can increase the risk of personal in jury
and death by p reventing an airbag from de­
p loying when needed or deploy ing an a irbag
unexpectedly:
-
- Never cover, obstruct, or change the steer­
ing wheel ho rn pad or airbag cover or the in­
s trumen t panel or modify them in any way.
- Never attach any objects s uch as c up ho lde rs
or telephone mountings to the surfaces cov­
ering the a irbag un its.
- For cleaning the horn p ad or instr ument
panel, use only a soft, dry doth or one mois­
tened w ith plain water . Solvents or cleaners
could damage the airbag cover or change
the stiffness o r strength of the material so
that the airbag cannot deploy and protect properly.
- Never repair, ad just, or change any parts o f
the airbag system.
- All work on the steering wheel, instrument
panel, front seats or e lectr ica l system ( in­
cluding the installation of a udio eq uipment,
cellular te lephones and CB radios, etc.)
m ust be performed by a qualified techn ician
who has the training and spec ial equipment
necessary.
- For any work on the airbag system, we
strong ly recommend tha t you see you r au­
thori zed A udi dealer or qualified wo rkshop.
- Never modify the front bumper or pa rts of
the vehicle body.
- Always make sure that the side a irbag can
inflate w ithout interfe rence:

Important safety instructions on the side
airbag system
Airbags are only supplemental restraints. Always
p roperly wear safety belts and ride in a proper
seating position.
There is a lot that you and your passengers must
know and act accord ingly to help t he safety be lts
and a irbags do the ir job to provide supplemental
protection.
A WARNING
An inflating side airbag can cause serious or
fatal injury . Improperly wearing safety belts
and improper seating positions increase the
r isk of serious personal injury and death
whenever a vehicle is being used .
- In order to reduce the risk of injury when
the supplemental s ide airbag inflates:
- Always sit in an up right posit ion and never
lean ag ainst the area where the s upple­
mental side airbag is located.
-
- Never let a chi ld or anyone else rest the ir
head agains t the side t rim p anel in the
area whe re the supp lemental s ide a irbag
inflates.
- Always make sure that safety belts are
worn correctly,
- Do not let anyone sitting in the fron t seat
put their hand or any other parts o f the ir
body out of the window .
- Always make sure tha t the side airbag can
inflate without inter ference.
- Never install seat covers or rep lacement
upho lstery over the front seatbacks that
have not been specifically approved by
Aud i.
- Never use add itiona l seat cushions that
cover the areas where the s ide airbags de­
ploy .
- Damage to the origina l seat covers or to
the seam in the area of the side airbag
mod ule m ust always be repaired immed i­
ately by an authorized Audi dealer.
- Objects between you and the airbag can in­
cr ease t he risk of inju ry in an accident by in­
te rfe ring w ith the way the airb ag unfo lds or
214 by being pushed

"A IRBAG" on the seat backrests .
- Such objec ts and accessories can become
dange ro us projecti les and cause injury
when the supplemental side airbag de­ ploys.
- Never carry any objects or pets in the de ­
ployment space between them and the
airbags or allow children or other passen­
gers to trave l in this position .
- Always prevent the side airbags from being
damaged by heavy objects knocking against
or hitting the sides of the seatbacks.
- The a irbag system can only be triggered
once . If the airbag has been triggered, the
system must be replaced by an authorized
Aud i dealership.
- Damage (cracks, deep scratches etc.) to the
or iginal seat covers or to the seam in the
area of the side airbag module must always
be repaired immediately by an authorized
Aud i dea le r.
- If ch ildren are seated imprope rly, thei r risk
of injury increases in the case of an accident
~ page 216, Child safety .
-Never attempt to mod ify any components of
the airbag system in any way.
- In a side collision, side airbags will not func­
tion properly if sensors cannot correctly measure increasing air press ure inside the
doors when a ir e scapes th rough large r, un­
closed openings in the door p anel.
- Never dr ive with interior door t rim panels
removed.
- Never dr ive when parts have been re­
moved from the inside door panel and the

d icator light also blinks for approximate ly one
minute and t hen stays on, there is system ma l­
function. The following are examples of sit ua­
tions that cou ld cause a malfunction:
-If the message appears at the end o f the adap ­
tation phase, the system may not detect one or
severa l of the wheel senso rs necessa ry for pres ­
s ur e monitoring. This may result from one or
more wheels being installed without wheel sen­
sors or with incompatible wheel sensors .
- A wheel sensor o r another component has
failed.
- Using snow cha ins can affect the f unction of
the system because of the shie lding effect of
the cha ins.
- The tire pressure monitor ing system is not
available due to a malfunction.
- Transmitters with the same frequency, such as
headphones or remote-controlled dev ices, may
cause a temporary system malfunction due to
the strong electromagnetic field .
