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.
292
- Never attach any objects s uch as c upholders
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
u pholstery 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 always 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 268, Gener­
al information.
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 indicator ligh t in the instrument
panel
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
294
- in rollovers
- in the event of a system malfunction (warning/
ind icator light is on)
¢page 32 .
A WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
the proper seating
position ¢ page 287 .
-If the airbag indicator light ¢ page 32
comes when the veh icle is being used, have
the system inspected immediately by your
author ized 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. 250 In 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 287, fig. 247 .
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.

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
Q page 268,
Airbag system Qpage 277, Ch ild safety
c::> page 302 .
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
- two rear side airbags*
- the airbag warning light in the inst rument 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 ign it ion, the air­
bag system indicator light will come on for a few
seconds (self diagnostics).
The side airbag system supplements the safety
be lts and can help to reduce the risk of injury to
the driver's, front and rear* passenger 's upper
torso on the side of the vehicle that is struck in a
side co llision. The a irbag dep loys only in side im­
pacts and on ly when the vehicle acceleration reg­
istered by the control unit is high enough . If this
rate is below the reference value programmed in­
to the control un it, the side airbags will not be
tr iggered, even though the car may be badly
damaged as a result of the collision.
It is not pos­
sib le to define an a irbag tr igger ing range that
will cover every possible angle of impact, since
the circumstances will vary considerably between
one collision and another . Important factors in­
clude, for example, the nature (hard or soft) of
the impacting object, the angle of impact, vehicle
speed, etc.
Q page 297, Important safety in­
structions on the side airbag system.
Aside from their normal safety function, safety be lts 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-
296
pant res traint system in your vehicle . Always re­
member that the side airbag system can only
help to protect you if you are wear ing 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

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 ing, friction
burns and minor abrasions can also be assoc iated
with deployed side airbags. Remember too, side
a irbags w ill 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 icat ion
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 deploy
on ly once and only 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 turned off
- in side co llisions 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
curta in airbags and side a irbags may be triggered
together .
&_ WARNING
-Safety belts and the airbag system will only
provide protection when occupants are in
the proper seating position

side impacts and only when the vehicle accelera­
tion reg istered by the control un it is high
enough. If th is rate is below the reference value
programmed into the control unit, the side cur ­
tain airbag will not be triggered, even though the
car may be badly damaged as a result of the colli­
sion.
It is not possib le to define an airbag tr igger­
i ng range tha t will cover every possib le ang le of
impact, since the circ ums tances will vary consid­
e rably between one co llision and another . Impor ­
tant factors include, for examp le, the nat ure
(hard or soft) of the impact ing ob ject, the angle
of impact, vehicle speed, etc.

Airbag sys tem
The side curtain airbag system basically
cons ists of :
-The e lectronic control mod ule and externa l side
impact sensors
- The side curtain airbags above the windows of
the outer seating positions with eject ion mit i­
gation features
- The airbag indicator light in the instrument
panel
T he airbag system is mon itored e lectron ica lly to
make certain 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 diagnostics).
The side curtain airbag is not activated :
-if the ignition is turned off
- in side co llisions whe n the ac celeration meas-
ured by the sensor is too low
- in rear -end co llisions.

Airbag syste m
How side curtain airbags work
Applies to: ve hicles w ith s ide curta in a irbags
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 . 255 Illustration of p rinc iple: Inflated s ide curta in air­
bags on the left side
The s ide curtain airbags inflate between the oc­
cupant and the windows in a side collision
¢ fig. 255 .
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 A IRBAG label. I n order
to help p rovide this addit ional protection, the
side curtain airbag must inflate within the blink
of an eye at very high speed and with great force .
The s ide curta in a irbag 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
especially to
children ¢ page 302.
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
Appl ies to : vehicles wi th side curtain airbags
Airbags ore only supplemental restraints . Always
properly wear safety belts and ride in a proper seating position .
There is a lot that you and your passengers must
know and do to help the safety belts and airbags
do their job to p rovide supplemental protection .
A WARNING
-Improperly wearing safety be lts and improper
seating positions increase the risk of serious
personal injury and death whenever a vehicle
is being used.
- Never let occupants place any parts of their
bodies in the area from which the side cur­
tain airbag inflate.
- Always make sure that the side curtain air­
bags can inflate without interference.
- Use the bu ilt-in coat hooks only for light ­
weight clothing. Never leave any heavy or
sharp-edged objects in the pockets that may
interfere with a irbag deployment and can
cause personal injury in a collision.
- Never use hangers to hang clothes on the
hooks.
- On ly use factory-installed sun shades or, if
shades installed after the vehicle leaves the
factory, use only genu ine Audi sun shades.
- Never swing the sun visors over to the s ide
w indows if things such as pens, garage door
openers, hands-free speakers, etc . are at­
tached to the sun v isors. They could come
loose and cause serious injury if the side cu r­
tain airbag infla tes.
- 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 zone of a s ide curtain airbag .
- The airbag deployment zones must be kept clear at al l t imes. Make sure there are no
objects, pets, o r othe r persons in the space
between any vehicle occupant and any air­
bag at any time .
- Do not attach any accessories to the doors.

A WARNING
Child ren on the front seat of any car even w ith
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 ch ild 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 fac ing ch ild
safety seat on the front passenger seat in
exceptiona l circumstances and the
PA SSEN ­
GE R 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 chi ld seats installed on the
front passenger seat may interfere with the deployment of the a irbag and cause serious
personal injury to the child.
- If except ional 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 fo rward-facing
seat has been designed and certified by its manufacturer for use on a front passenger
seat with a front and s ide a irbag.
- Always carefully follow the manufacturer's instructions provided with the child seat
or infant carrier.
- Never install a chi ld restraint without a
properly attached top tether strap if the
child restraint manufacturer's instructions require the top tether strap to be used.
Ch ild safety
-Never put the forward-facing child re­
straint up against or very near the instru­
ment panel.
- Applies to: vehicles with safety be lt height
adjustment: Always set the safety belt up­
per anchorage to the adjustment pos ition
that permits proper installation in accord­
ance with the child restraint manufactur­
er's instructions.
- Always move the front passenger seat to the h ighest position in the up and down
adjustment range and move it back to the
rearmos t position in the seat's fore and
a ft ad justment range, as far away from
the a irbag as poss ible, before installing
the forward-facing child restraint .
- Always make sure that the safety belt up­
per anchorage is behind the chi ld restraint
and not next to or in front of the child re­
straint so that the safety belt will be prop­
erly pos it ioned.
- 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, CO player, electronic games de­
vice, power inverter or seat heater fo r
ch ild seats) . These may influence the elec­
trical capacitance measu red by the capac i­
tive passenger detec tion system and can
also fly around in an acc iden t and c ause
serious personal injury .
- Never place or use any ele ct rical devi ce
(such as a laptop, CO player, electroni c
games device, powe r inverter or seat heat ­
er for child seats) on the front passenger
seat if the device is connected to the
12-
vo lt socket or the cigarette lighter socket.
- If a seat heater has been retrofitted or
otherw ise added to the front passenger
seat, never insta ll any child restraint sys­
tem on this seat.
- Make su re that there are no wet objects
(such as a wet towe l) and no water or oth­
er liquids on the front passenger seat
cush ion.

(D Tips
Always replace child restraints that were in­
stalled in a vehicle during a crash. Damage to
a child restraint that is not visible could cause
it to fail in another collision situation.
Advanced front airbag system and children
Your vehicle is equipped with an "Advanced Air­
bag System" in compliance with United St ates
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 Advanced Airbag system in your vehicle has
been certified to meet the "low-risk " require­
ments for 3- and 6-year old children on the pas­
senger side and small adults on the driver side.
The low risk deployment criteria are intended to
reduce the risk of injury through interaction with
the airbag that can occur, for example, by being
too close to the steering wheel and instrument
panel when the airbag inflates. In addition, the
system has been certified to comply with the
"suppression" requirements of the Safety Stand­
ard, to turn off the front airbag for infants up to 12 months who are restrained on the front pas-
304
senger seat in child restraints that are listed in
the Standard.
Even though your vehicle is equipped with an Ad­
vanced Airbag system, all children, especially
those 12 years and younger, should always ride
in the back seat properly restrained for their age
and size. The airbag on the passenger side makes
the front seat a potentially dangerous place for a child to ride. The front seat is not the safest place
for a child in a forward-facing child safety seat. It
can be a very dangerous place for an infant or a
larger child in a rearward-facing seat.
The vehicle's Advanced Airbag System has a ca­ pacitive passenger detection system in the front
passenger seat cushion that can detect the pres­
ence of a baby or a child in a child restraint sys­
tem on this seat.
The capacitive passenger detection system regis ­
ters the changes that result in an electrical field
when a child, a child restraint , and a baby blanket
are on the front passenger seat. The change in
the measured capacitance due to the presence of
a child, a child restraint, and a baby blanket on
the front passenger seat is related to the child
restraint system resting on the seat. The meas­
ured capacitance of a child restraint system var­
ies depending on the type of system and specific
make and model.
The electrical capacitance of the various types, makes, and models of child restraints specified
by the U.S.National Highway Traffic Safety Ad­
ministration (NHTSA) in the relevant safety
standard are stored in the Advanced Airbag Sys ­
tem control unit together with the capacitances
typical of infants and a 1-year old child. When a
child restraint is used on the front passenger
seat with a typical 1 year-old infant, the Ad­
vanced Airbag System compares the capacitance
measured by the capacitive passenger detection
system with the data stored in the electronic con­
trol unit .
Child restraints and Advanced Airbags
Regardless of the child restraint that you use,
make sure that it has been certified to meet Safe -
ty Standards and has been certified by its
..,.

<( a, .... N ,....

manufacturer for use with an airbag. Always be
sure that the child restraint is properly installed
at one of the rear seating positions . If in excep­
tional circumstances you must use it on the front
passenger seat, carefully read all of the informa­
tion on child safety and Advanced Airbags and heed all of the appl icable WARNINGS . Make cer­
tain that the child and ch ild restraint are correct­
ly recognized by the capacitive passenger detec­
tion system in the front passenger seat, that the
front passenger airbag is turned off, and that the
airbag status is always correctly signaled by the
PASSENGER A IR BAG OFF 1,;; light.
Many types and models of ch ild rest rai nts have
been available over the yea rs, new mode ls are in­
troduced regularly incorporating new and im­
proved designs and older mode ls are taken out of
product ion. Chi ld restraints are not standardized.
Ch ild restraints of the same type typically have
d ifferent weights and sizes and different "foot­
prints", the s ize and shape of the bottom of the
chi ld 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 req uirements fo r advanced airbags wi th
each and every child restraint that has ever been
sold in the past or will be sold over the course of
the useful life of your vehicle.
F or 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 certify compli­
ance of the Advanced Airbag System in your vehi­
cle with the suppression requ irements of Federal
Motor Vehicle Safety Standard 208 . These child
restraints are:
