More important things to know about front
airbags
Fig. 162 Inflated front a irbags
Safety bel ts a re 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 p rovide addi­
tional protect ion for the chest a nd face of the
d river 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 .
Because airbags inflate in the blink of an eye w ith
great force, things you have on your lap or have placed on the seat cou ld 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. Th is 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
p lemental a irbag system is designed to reduce
the likel ihood of ser ious injuries, o ther inj uries,
for example swe lling, b ruising and mino r abra­
sions, c an a lso happe n when airbags inflate. Ai r­
bags do not protect the arms o r the lowe r parts
of the body . Front airbags supplement the three
point safety belts only in some frontal collisions

Airb ag sys tem
Front a irbags will not deploy :
-if the ignition is sw itched off when a crash oc-
curs,
- in side co llisions,
- in rear-end col lisions,
- in rollovers,
- when the crash deceleration measured by the
ai rbag system is less than the m inimum thresh ­
old needed for airbag deployment as registered
by the electron ic con trol un it.
The front pa ssen ger airbag will als o not
deploy:
- when the fron t passenger seat is not occupied,
- when the e lectr ica l capacitance measured by
the capacit ive passenger detection system for
the front passenger seat ind icates that the pas­
senger side frontal airbag must be switched off
by the ele ctro nic con trol un it ( the

A WARNING
Sitting in the wrong position can increase the
risk of ser ious injury in crashes .
- To reduce the risk of injury when the airbags in flate, the driver and passengers must al ­
ways sit in an upright posit ion, m ust not
lean aga inst or place any part of their body
too close to the area where the airbags are
located.
- Occupants who are unbelted, out of positio n
or too close to the airbag can be serio usly
i nju red by an airbag as it unfolds with great
force in the blink of an eye~

A WARNING
-A child in a rearward-facing child seat ins tal­
l ed on the front passenger seat will be se ri­
ously injured a nd ca n be killed i f the front air­
bag inflates -
even with an Advanced Airbag
System .
- The infla ting airbag will h it the chi ld s eat o r

Repair , care and disposal of the airbags
Parts of the a irbag system are installed at many
different places on your Audi. Installing, remov­ ing, servic ing or repa iring a part in an area of the
ve hicle can damage a part of an airbag system
and prevent that system from working properly
i n a collision .
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
env ironment.
A WARNING
Improper care, serv icing and repai r proce­
dures can increase the r is k of personal injury
and death by preventing an airbag from de­
ploying when needed or dep loying an airbag
unexpectedly:
-
- Never cover, obstruct, or change the stee r­
ing wheel horn pad or airbag cover or the in­
strument pane l or modify them in any way.
212
- 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 or strength of the material so
that the airbag canno t deploy and p rotect
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 installation of a udio eq uipment,
cellular telephones and C B radios, etc.)
m ust be perfo rmed by a qualified 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 workshop.
- 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 over the front seatbacks that
have not been specifically 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 alway s be repaired immedi­
ate ly by an autho riz ed Au di dealer.
- The a irbag system can deploy on ly once. Af­
ter an airbag h as been deployed, i t m ust be
repla ced with new replacement parts de­
signed and approved espec ia lly for your
Audi model version . Replacement of com­
plete airbag systems or airbag components
must be perfo rmed by qua lified workshops
only. Make su re that any airbag service ac­
tion is entered in your A udi Warranty

Airbag system
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 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 189, Gener­
al notes.
Remember too, airbags will deploy only once and
only in certain k inds 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
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 substitute for the safety belt. The a irbag
system works most effectively when used with
the safety belts. Therefore, always wear your
safety belts correct ly.
It is important to remember that while the sup­
p lemental knee airbag system is designed to re­
duce the likelihood of serious injuries, other inju ­
ries, for example, swe lling, bruising and minor
abrasions and friction burns can also occur when
an airbag inflates .
The knee airbag system basically consists of:
- T he electronic control module
- T wo inflatab le airbags (airbag and gas genera-
tor), one for the driver and one for the front
passenger
- The airbag warning light in the instr ument clus­
ter
The knee airbag system will not deploy:
-whe n the ignition is switched off
- in frontal collisions when the deceleration
measured by the control un it is too low
- in side collisions
- in rear-end collisions
214
- in rollovers
-in the event of a system malfunction (warning/
indicator light is on)
¢ page 15.
A WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
the proper seating position¢
page 207 .
-If the airbag indicator light¢ page 15
comes when the veh icle 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
The risk of injury to the leg area con be reduced
by fully inflated knee airbags.
Fig. 165 I n flated a irbags protect ing in a fro nta l coll ision
The knee airbag system has been designed so
that the airbags for the dr iver and front passen­
ger dep loy in certain but not all fronta l 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
prope llant 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 207, fig. 162 .
Although they are not a soft pillow, they can
"cushion" the impact and in this way they can
help to reduce the risk of injury to the lower ex­
tremities.

Airbag system
the occupant sitting next to it is not seated prop­
erly. The side airbag for the front passenger seat
can be used with properly installed child re­
straints. Please be sure to read the important in­
formation and warnings whenever using a child
restraint in a vehicle: Safety belts
Qpage 189,
Airbag system Qpage 197, Child safety
c::;, page 2 21 .
The side airbag system basically consists of:
-the e lectronic control modu le and externa l side
impact sensors
- the two side airbags located in the sides of the
front backrests
- the airbag warning light in the instrument clus-
ter.
The airbag system is monitored electronically to
make certa in that it is functioning properly at all
times. Each time you turn on the ignition, the air­
bag system indicator light will come on for a few
seconds (self diagnost ics).
The side airbag system supplements the safety
be lts and can help to reduce the risk of injury to
the driver 's and front passenger's upper torso on
the side of the vehicle that is struck in a side col­
lision . The airbag deploys in side impacts and on­
ly when the vehicle acceleration registered by the
control unit is high enough. If this rate is below
the reference value programmed into the control
un it, the side a irbags w ill not be triggered, even
though the car may be badly damaged as a res ult
of the collision.
It is not possible to define an air­
bag tr igger ing range that will cover every poss i­
b le ang le of impact, since the circumstances will
vary considerably between one collision and an­
other. Important factors include, for example,
the nature (hard or soft) of the impacting object,
the angle of impact, vehicle speed, etc.
Q page 217, Important safety instructions on
the side airbag system .
Aside from their normal safety function, safety
belts work to help keep the driver or front pas­
senger in pos it ion in the event of a s ide collision
so that the side a irbags can provide protection .
The airbag system is
not a subst itute for your
safety belt. Rather, it is part of the overall occu­
pant restraint system in your vehicle . Always re-
216
member that the side airbag system can only
help to protect you if you are wearing your safety
belt and wearing it properly. This is another rea­
son why you should a lways wear your safety
belts, not just because the law requires you to do
so
Q page 189, General notes.
It is important to remember that while the sup­
plemental side airbag system is designed to re­
duce the likelihood of ser ious injuries, other inju­
ries, for example, swelling, bru is in g, friction
burns and minor abrasions can also be assoc iated
with deployed side airbags. Remember too, side
airbags will dep loy only once and only in certa in
kinds of accidents - your safety belts are always
there to offer protection.
Vehicle damage, repair costs or even the lack of
vehicle damage are not necessarily an ind ication
of over -sens itive or fa iled airbag activation. In
some collisions, both front and side airbags may
inflate. Remember too, that airbags wi ll dep loy
on ly once and on ly in certain kinds of collisions -
your safety be lts are always there to offer protec­
tion in those accidents in which airbags are not
supposed to deploy or when they have already
deployed .
The side airbag system will not deploy:
-when the ignition is switched off
- in side collisions when the acceleration meas -
ured by the sensor is too low
- in front-end collisions
- in rea r-end collisions
- in rollovers .
In some types of accidents the front airbags, side
curtain airbags and side a irbags may be triggered
together .
A WARNING
-Safety belts and the airbag system will only
provide protect ion when occupants are in
the proper seating position
c::;, page 217.
- If the airbag ind icator light Qpage 15

the airbag will inflate when it is not sup­
posed to, or wi ll not inflate when it should .

below the reference value programmed into the
control unit, the side curtain airbag will not be
tr iggered, even though the car may be bad ly
damaged as a result of the collision. It is not pos­
sible to define an airbag triggering range that
will cover every possib le angle of impact, since
the circumstances will vary considerably between one co llision and another. Important factors in­
clude, for example, the nature (hard or soft) of
the impacting object, the angle of impact, vehicle speed, etc.¢
page 219, How side curtain air­
bags work.
Aside from their normal safety function, safety
be lts work to help keep the d river or fron t pas­
senger in posit ion in the event of a co llision so
that the side curtain airbags can provide protec ­
tion.
The airbag system is not a s ubst itu te for yo ur

protect you if you are wearing your safety belt
and wear ing it properly . This is another reason
why you should always wear your safety belts,
not just because the law requires you to do so
¢ page 189, General notes.
It is important to remember that while the side
curtain airbag system is des igned to help reduce
the likelihood of serious injuries, other injuries,
for example, swelli ng, bruising, fr iction burns
and minor abrasions can also be associated with
these airbags upon deployment . Remember too,
these airbags will deploy only once and only in certa in kinds of acc idents - you r safety belts are
always there to offer protection.
The side curtain airbag system basically
consists of:
- T he elec tronic contro l module and external side
impact sensors
- T he side c urtain airbags above the front and
rea r side windows with ejection mitigation fea ­
tures
- T he airbag indicator light in the instrument
panel
The airbag system is monitored elec tronically to
make certain it is f unct ion ing properly at all
Airb ag sys tem
times. Each time you switch on the ignition, the
airbag system indicator light wi ll come on for a
few seconds (self d iagnostics).
Th e side curtain airbag is not activ ated:
- if the igni tion is sw itched off,
- in side co llisions when the accele ration meas-
ured by the sensor is too low,
- in rear-end co llisions.
A WARNING
- Safety belts an d the airbag system will only
p rovide protect ion when occup ants are in
the proper seat ing position ¢
page 44,
Seats and storage .
- If the airbag ind ic a tor light~ page 15
comes when the veh icle is being used, have
the system inspected immediately by your
authorized Audi dealer . It is possib le that
the airbag will inflate when it is not sup­
posed to, or w ill not inf late when it should.
How side curtain airbags work
Side curtain airbags con work together with side
airbags to help reduce the risk of head and upper
torso injuries for occupants who ore properly re­
strained.

Child safety
A WARNING
Children on the front seat of any car even with
Advanced Airbags can be seriously injured or
even killed when an airbag inflates. 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 in­
flates.
- 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, or
door.
- 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 in
exceptional circumstances and the
PASSEN­
GER AIR BAG OFF~;
light does not come
on and stay on, immediately install the rear­
facing child safety seat in a rear seating po­
sition and have the airbag system inspected
immediately by your Audi dealer.
A WARNING
- Forward-facing child seats installed on the
front passenger seat may interfere with the deployment of the airbag and cause serious
personal injury to the child.
- If exceptional circumstances require the use
of a forward-facing child restraint on the
front passenger's seat, the child's safety and well-being require the following special
precautions to be taken:
- Always make sure that the forward-facing
seat has been designed and certified by its
manufacturer for use on a front passenger
seat with a front and side airbag.
