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

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

flates.
- Never p lace or attach accessories or other
objects (such as cup holders, telephone brackets, or even large, bulky objects) on
the doors, over or near the area marked
"AIRBAG" on the seat backrests.
- Such objects and accessories can become
dangerous projectiles and cause in ju ry
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 travel in this position.
- Always use the built-in coat hooks only for
lightweight clothing. Never leave any heavy
or sharp-edged objects in the pockets that
may interfere w it h side airbag deployment
and can cause personal i njury in an accident.
- Always prevent the side airbags from being
damaged by heavy objects knocking against
or hitting the sides of the seatbacks.
- The airbag system can only be triggered
once. If the airbag has been triggered, the
system must be replaced by an author ized
Audi dealership.
- Damage (cracks, deep scratches etc.) to the
orig inal seat covers or to the seam in the
area of the side a irbag mod ule m ust always
be repa ired immed iate ly by an authorized
Audi dealer .
- If children are sea ted improperly, their r is k
of injury increases in the ca se of an ac ciden t
~ page 221, Child safety .
-Never attempt to modify any components of
the a irbag sys tem in any way.
- In a side collision, s ide a irbags w il l not fu nc­

- Never drive when loudspeakers in the
doors have been removed unless the
speaker holes have been properly closed.
- Always make certain that openings are
covered or filled if additional speakers or
other equipment is installed i n the inside

Side curtain airbags
Description of side curtain airbags
The side curtain airbag system can provide sup­
plemental protection to properly restrained oc­
cupants.
Fig. 168 S id e curt ain airbags, driver's sid e: side curtain a ir ­
bag locatio n
The side curtain airbags are located on both sides
of the inter ior above the fro nt and rear side win­
dows~
fig. 168. T hey are identified by the word
"AIRBAG" on the windshie ld frame and the cen­
ter roof p illar .
The side curtain airbags contain features that provide ejection mitigation to help prevent veh i­
cle occupants or parts of their bodies from being
completely or part ially ejected from the vehicle
interior in certain side impacts and vehicle roll­
overs .
The side c urtain airbag system supplements the
safety belts and can help to reduce the risk of in­
jury for occupants' heads and upper torso. The
side curtain airbag inflates in side impacts and
only when the ve hicle acceleration registered by
the control unit is high enough .

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
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 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 ¢

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.
Fig. 169 Illustration of princip le: Inflated s ide curta in air­
bags on the left s ide
The side curtain airbags inflate between the oc­
cupant and the windows on the side of the vehi-

¢fig . 169 .
When the system is triggered, the side curtain
airbag is filled with propellant gas and breaks
through a seam above the front and rear side
windows identified by the AIRBAG label. In order

219

Airbag syste m
to help provide this additional protection, the
side curtain airbag must inflat e within th e blink
of an eye at very h igh speed and with great force .
The side curtain airbag could injure you if your seating position is not proper or upright or if
items are located in the area where the supple ­
mental side curtain airbag inflates . This applies
especia lly to children
~ page 221 .
Although they are not a soft pillow, side curtain
airbags can "cushion" the impact and in this way
they can help to reduce the risk of injury to the head and the upper part of the body .
A fine dust may develop when the airbag deploys.
This is quite normal and does not mean there is a
fire in the veh icle.
Important safety instructions on the side
curtain airbag system
Airbags are only supplemental restraints . Always
properly wear safety belts and ride in a proper
seating position.
There is a lot that you a nd your passengers must
know and do to help the safety be lts and airbags
do their job to provide supp lemental protect ion.
_& WARNING
Improperly wearing safety belts and improper
seating positions increase the risk of serious
personal injury and death whenever a vehicle
is being used.
- Never let occupants p lace any parts of their
bodies in the area from which the side cur­
ta in a irbag inflate.
- Always make sure that the side curtain air­
bags can inflate without interference .
- Use the built -in coat hooks on ly for light­
weight clothing. Never leave any heavy or sharp-edged objects in the pockets that may
interfere w ith airbag deployment and can
cause personal injury in a collision.
- Never use hangers to hang clothes on the hooks.
- Only use factory-installed sun shades or, if
shades installed after the veh icle leaves the
factory, use only genuine Aud i sun shades .
220
-Never swing the sun visors over to the side
w indows if things such as pens, garage door
openers, hands-free speakers, etc. are at­
tached to the sun visors . They could come
loose and cause serious injury if the side cur­
tain airbag inflates.
- A deploying airbag inflates in a fract ion of a
second and with great force.
- Never attach objects to the cover or in the
deployment zo ne of a s ide curtain airbag .
- The a irbag deployment zones must be kept
clear at all times . Make sure there are no
objects , pets, or other persons in the space
between any vehicle occupant and any air­
bag at any time .
- Do not attach any accessories to the doors .
_& WARNING
-The a irbag system can deploy on ly once . If
the airbag has been trigge red, the system
m ust be rep laced by an authorized A udi
dea le r o r qualified workshop.
- Always have wo rk invo lv ing the side curtain
airbag system, remova l and installat ion of
the airbag components, or other repairs
performed by a q ualified dealership. Other­
wise the airbag system may not work cor­
rectly .
- Never attempt to mod ify any components of
the airbag system in any way .

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.
-Always carefully follow the manufacturer's
instructions provided with the child seat
or infant carrier.
- Never install a child restraint without a
properly attached top tether strap if the
child restraint manufacturer's instructions
require the top tether strap to be used.
222
-Never put the forward-facing child re­
straint up against or very near the instru­
ment panel.
- Always move the front passenger seat to
the highest position in the up and down
adjustment range and move it back to the
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible, before installing
the forward-facing child restraint.
-Always make sure that the safety belt up­
per anchorage is behind the child restraint
and not next to or in front of the child re­
straint so that the safety belt will be prop­
erly positioned.
- Always make sure that nothing prevents
the front passenger's seat from being
moved to the rearmost position in its fore
and aft adjustment range.
- Never place objects on the seat (such as a
laptop, CD player, electronic games de­
vice, power inverter or seat heater for
child seats). These may influence the elec­
trical capacitance measured by the capaci­
tive passenger detection system and can
also fly around in an accident and cause
serious personal injury.
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat heat­
er for child seats) on the front passenger
seat if the device is connected to the 12-
volt socket or the cigarette lighter socket.
-If a seat heater has been retrofitted or
otherwise added to the front passenger
seat, never install any child restraint sys­
tem on this seat.
- Make sure that there are no wet objects
(such as a wet towel) and no water or oth­
er liquids on the front passenger seat
cushion.
- Always make sure that the
PASSENGER
AIR BAG OFF~;
light comes on and stays
on all the time whenever the ignition is
switched on.
- If the PASSENGER AIR BAG OFF,;; light
does not come on and stay on, immediate- ly install the forward-facing child seat in a

applicab le WARN INGS . Make certain that the
chi ld and child restraint are correct ly recognized
by the capacit ive passenger detection system in
the front passenger seat, that the front passen­
ger airbag is turned off, and that the airbag sta­
tus is always correctly signaled by the
PA SS EN ­

Many types and models of child restraints have
been available over the years, new models are in­
troduced regularly incorporat ing new and im ­
proved designs and older models are taken out of
p roduct ion . Ch ild restraints are not standardized.
Ch ild rest raints of the same type typ ica lly have
d ifferent weights and s izes and differen t "foot­
prints", the s ize and shape of the bottom of the
child restraint that sits on the seat, when they
are insta lled on a vehicle seat. These differences
make it virtually impossible to certify compliance
with the requirements for advanced airbags with
each and every ch ild restraint that has ever been
sold in the past or will be sold over the course of
the useful life of your veh icle .
For this reason, the Un ited States National High­
way Traffic Safety Administration has published a list of specific type, makes and models of child
restraints that must be used to cert ify compli­
ance of the Advanced Airbag System in your vehi­
cle with the supp ression requ irements of Fede ral
