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. Installing, remov­
ing, servicing o r repa iring a part in an area of the
vehicle can damage a pa rt of an airbag system
and prevent that system from working properly in a co llision.
There are some importa nt 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.
A WARNING
Improper care, serv icing 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 :
-
-Never cover, obstruct, or change the steer­
ing wheel horn pad or a irbag cover or the in ­
strument panel or mod ify them in any way .
- Never attach any objects such as cupholders
or telephone mountings to the surfaces cov­
er ing the airbag units .
- For cleaning the horn pad or instrument panel, use only a soft, dry cloth or one mois­
tened with plain water. Solvents or cleaners
cou ld damage the a irbag cover or change
the stiffness or strength of the mater ial so
that the airbag cannot dep loy and protect
properly.
- Never repair, adjust, or change any parts of
the airbag system.
- All wo rk on the stee ring wheel, instr ument
pane l, front seats or electrical system (in­
cluding the installation of audio equipment,
cellu lar telephones and CB radios, etc .)
must be performed by a qualified technician
Airb ag sys tem
who has the training and special equ ipment
necessary.
- For any wo rk 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 a irbag can
inflate without interference:
- Never install seat covers or replacement
upholstery ove r the front seatbacks that
have not been specifica lly approved by
Audi .
- Never use addi tional seat c ushions that
cove r 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 must a lways be repaired immedi­
ate ly by an authorized Aud i dealer.
- The airbag system can be activated only
once . A fter an airbag has inflated, it must
be replaced by an authorized Audi dealer or
qualified technic ian who has the technical
information, t raining and spec ial equ ipment
necessary.
- The airbag system can be deployed only
once . After an airbag has been deployed, it
must be replaced with new rep lacement
parts des igned and approved especially for
your Aud i model version. Replacement of
comp lete airbag systems or airbag compo­
nents must be performed by qualified work­
shops only. Ma ke sure that any airbag serv­
ice act ion is en tered in your Aud i Wa rranty
& Maintenance booklet under AIRBAG RE ­
PLACEMENT RECORD.
- In accidents when an airbag is dep loyed, the
vehicle battery separates the alternator and
the starter from the veh icle electrical sys­
tem for safety reasons w ith a pyrotechnic
circu it interrupter.
- Wo rk on the pyrotechnic c ircuit inte rrupt­
er must on ly be performed by a qu alified
dealer -risk of an acc ident!
- If the vehicle or the circuit interr upter is
scrapped, all applicable safe ty p recautions
must be followed .

Airbag system
@ For the sake of the environment
Undeployed airbag modu les and pretension­
ers might be classified as Perchlorate Materi­
al -special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlo­ rate . When the vehicle or parts of the re­
straint system including airbag modules safe­
ty belts with pretens ioners are scrapped, all
applicable laws and regulat ions must be ob­
served. Your authorized Audi dealer is familiar
with these requirements and we recommend
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
cha nge the way that the Advanced Airbag System
pe rforms in a crash. For example, using tire-r im
comb inat ions not approved by Audi, lower ing the
veh icle, changing the stiffness of the suspens ion,
including the spr ings, 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 deploy if
the changes had not been made. Other ki nds of
changes may reduce the force levels measured by
the sensors and preven t the airbag from deploy­
ing when it should .
A WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced A irbag performance and in ­
crease the risk of serious personal injury in a
crash.
- Never install suspension components that
do not have the same performance charac­
teristics as the components originally insta l­
led on your veh icle.
- Never use tire-rim comb inations that have
not been approved by Audi.
152
A WARNING
Items stored between the safety belt buckle
and the center console can cause the sensors in the buckle to send the wrong information
to the electronic control module and prevent
the Advanced A irbag System from working
properly.
- Always make sure that nothing can inte rfe re
w ith the safety belt buckles and that they
are not obstructed.
Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
Fig. 156 S ide ai rbag locatio n in the dr ive r's seat
The side airbags are located in the sides of the
front seat backrests
¢ fig . 156 and the rear back­
rest facing the doors. They are identified by the
word "AIRBAG".
The side airbag system basically consists of:
-the electronic control module and external side
impact sensors
- the two airbags located in the sides of the front
backrests and the two airbags" located in the
rear backrest
- the airbag warning light in the instrument clus-
ter.
The airbag system is monitored electronica lly to
make certain that it is functioning proper ly 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 airbag system supplements the safety be lts and can help to reduce the risk of injury to
the dr iver's and front passenger's upper torso on
the side of the vehicle that is struck in a side col­
lision . The airbag deploys on ly in side impacts
and only when the vehicle acceleration reg istered
by the control unit is h igh enough. If this rate is
be low the reference va lue programmed into the
control unit, the s ide airbags will not be tr ig­
gered, even though the car may be badly dam ­
aged as a result of the collision.
It i s not possib le
to define an airbag triggering range that wi ll cov­
er every possible angle of impact, since the cir ­
cumstances will vary considerably between one
coll is ion and another. Important factors include,
for example , the nature (hard or soft) of the im­
pacting object, the ang le of impact, vehicle
speed , etc .
r::;;, page 154, Important safety in­
structions on the side airbag system .
Aside from their normal safety function, safety
be lts work to he lp keep the driver or front pas­
senger in pos it ion in the event of a side collision
so that the s ide a irbags can provide p rotection.
The airbag system is
not a substitute for your
safety belt . Rather, it is part of the overall occu­
pant restraint system i n your veh icle . Always re­
member that the s ide airbag system can only
he lp to p rotect yo u if you a re wea ring your safety
be lt and wea ring it properly. This is another rea­
son why you shou ld always wear your safety
be lts, not just because the law requi res you to do
so
r::;;, page 130, General information.
It is important to remember that while the s up­
p lemental side ai rbag system is designed to re­
duce the like lihood of serious injur ies, other inju­
ries, for example, swelling, bruising, and minor
abrasions can a lso be associated with deployed
side airbags. Remember too , side airbags will de­
ploy only once and only in certain kinds of acci­
dents -your safety belts are always t here to offer
p rotection.
Vehicle damage, repair costs or even the lack of
vehicle damage are not necessarily an indication
of over-sensitive o r failed airbag activation . In
some coll is io ns, both front and s ide a irbags may
in flate. Remember too, that airbags will deploy
only once and only in ce rtain k inds of coll is ions -
Airb ag sys tem
your safety belts are always there to offer protec­
tion in those accidents in which airbags are not
s u pposed to deploy or when they have already
deployed .
The side airbag system w ill n ot deploy:
- when t he ignit io n i s t urned off
- in side co llisions whe n the acceleration meas-
ured by the sensor is too low
- in front-end coll is io ns
- in rear-end col lisions
- in rollovers .
In some types of accidents the front airbags, side
curtain airbags and side airbags may be triggered
together .
A WARNING
--Safety belts and the airbag system will only
p rov ide protect ion when occupants are in
the prope r seat ing pos ition
r::;;, page 154 .
- If the ai rbag ind icator light r::;;, page 19
comes when the veh icle is being used, have
the system inspected immedia tely by your
a uthor ized Audi dealer.
It is possib le th at
the airbag will inflate when i t is not sup­
posed to, or w ill not inf late w hen it should.
How supplemental side airbags work
Side airbags deploy ins tantly and can help re­
duce the risk of upper torso injuries for occu­
pants who ore properly restrained.

passenger. In order to he lp provide this add ition­
al protection, the side airbag must inflate within
a fraction of a second at very high speed and w ith
great force. The supplemental side airbag could injure you if your seating position is not proper or
upright or if items are located in the area where
the supplemental side airbag expands . This ap­
plies especially to children

This is normal and does not mean there is a fire
in the vehicle.
Important safety instructions on the side
airbag system
Airbags ore only supplemental restraints . Always
properly wear safety belts and ride in a proper
seating position.
There is a lot that yo u and your passengers must
know and act accord ingly to help the safety be lts
and airbags 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 se rious personal injury and death
w henever a vehicle is being used.
- In order to reduce the risk of injury when
the supplemental s ide airbag inflates:
- Always sit in an upright position and never
lean aga inst the area where the s upple-
mental side airbag is located.
- Never let a chi ld or anyone else rest their
head against the side trim panel in the
area where the supp lemental s ide airbag
inflates.
154 -
Always make sure that safety belts are
worn correctly,
- Do not let anyone sitting in the front seat
put their hand or any other parts of their
body out of the window.
- Always make sure that the side airbag can
inflate w ithout interference.
- Never install seat covers or replacement
upholstery ove r the front seatbacks that
have not been specifica lly approved by
A udi.
- Never use addi tional seat cush ions that
cover the areas where the side airbags de­
ploy .
- Damage to the orig inal se at cove rs or to
the seam in the area of the s ide airbag
module must a lways be repaired immedi ­
ate ly by an authorized Audi dealer.
- Objects be tween you and the airbag can in­
crease the r is k of injury in an acc ident by in­
terfering with the way the airbag unfolds or by being p ushed into you as the airbag in­
flates.
- Never place or attach accessor ies or other
obje cts (s uch as cupholders, telephone
bracke ts, or even l arge, bulk y objec ts) on
the doors, over or near the area marked
"AIRBAG" on the seat backrests .
- Such objec ts and accessories can be come
dange rous 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 use the b uilt-in coat hooks only fo r
lightweight clothing. Never leave any heavy
or sharp-edged objects in the pockets that
may inte rfere with s ide a irbag deployment
a nd can cause personal injury in an accident .
- 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 autho rized
Aud i dea le rship.

measure increasing air pressure inside the
doo rs when air escapes through larger, un­
closed open ings i n the door panel.
- Never drive with interior door trim pane ls
removed.
- Never drive when parts have been re­
moved from the inside door panel and the
openings they leave have not been proper­
ly closed.
- Never drive when loudspeakers in the
doors have been removed unless the
speaker ho les have been properly closed.
- Always make certain that openings are covered or fi lled if additiona l speakers or
other equ ipment is installed in the inside
door panels.
- Always have work on the doors done by an
author ized Audi dealer or qualified work­
shop.

Airbag system
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 another reason
why you should always wear your safety belts, not just because the law requires you to do so
¢ page 130, General information.
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, swe lling, bruising, and m inor abra­
sions can also be associated with these airbags.
Remember too, these airbags will dep loy o nly
once and only in certain kinds of accidents -your
safety belts are always there to offer protection .
The side curtain airbag system basically
consists of:
- The electronic control module and external side
impact sensors
- The side curtain airbags above the front and
rear side windows
- The airbag indicator light in the instrument
panel
The airbag system is monitored electronically to
make ce rta in it is fun ction ing p roperly at all
times. Each time you turn on the ignit ion , the air­
bag system indicator light will come on for a few
seconds (self diagnostics).
The side curtain airbag is not activated:
-if the ignit ion is tu rned off,
- in s ide collisions when the accelerat ion meas-
ured by the senso r is too low,
- in rear-end collisions,
- in rollovers.
A WARNING
-Safety belts and the a irbag system w ill only
provide protection when occupants are in
the proper seating position<>
page 59,
Seats and storage.
-If the airbag indicator light ¢page 19
comes when the vehicle is being used, have
the system inspected immediately by your
156
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 side curtain airbags work
Side curtain airbags can work together with side
airbags to help reduce the risk of head and upper torso injuries for occupants who are properly re­
strained.
Fig. 159 Illustration of principle: Inflated sid e curtain air ­
bags on the left side
The side curtain airbags inflate between the oc­
cupant and the windows on the side of the veh i­
cle that is struck in a side collision
¢ fig . 159 .
When the system is triggered, the s ide 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
to help provide this additional protection, the
s ide curta in airbag must inflate within the blink
of an eye at very high speed and with g reat fo rce .
The side curtain airbag could injure you if yo ur
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 chi ldren
¢ page 158.
Although they are not a soft pillow, side curtain
airbags can "cushion" the impact and in this way
they can help to reduce the r isk 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 vehicle.

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 and your passengers must
know and do to help the safety belts and airbags
do their job to provide supplemental protection.
_& 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 place any parts of their
bodies in the area from which the side cur­
tain airbags inflate.
- Always make sure that the side curtain air­
bags can inflate without interference. Un­
suitable accessories fitted inside the expan­
sion range of a head airbag can dangerously
interfere with its function. A deploying head
airbag develops enough force to catapult
any piece of add-on component out of its
path of inflation and into the passenger
compartment. An occupant hit by such a
projectile can suffer serious injury or death
¢ page 260, Technical Modifications.
- Do not swivel the sun visors to the side if
you have any objects clipped onto them (for
example pens). If the airbag should deploy,
you could be injured by these objects.
- Use the built-in coat hooks only for light­
weight clothing. Never leave any heavy or
sharp-edged objects in the pockets that may
interfere with airbag deployment and can
cause personal injury in an accident.
- Never use hangers to hang clothing from the hooks.
- Only use factory-installed sun shades or, in
the case of shades installed after the vehicle
leaves the factory, only Audi roll-up
sunscreens may be used
¢ page 260, Addi­
tional accessories and parts replacement.
- Always sit in proper seating position and
wear safety belts while traveling so that the

side curtain airbags can help provide protec­
tion.
- The airbag system can only be triggered
once. If the airbag has been triggered, the
system must be replaced by an authorized
Audi dealer or qualified workshop.
-Always have work involving the side curtain
airbag system, removal and installation of
the airbag components, or other repairs performed by an authorized Audi dealer or
qualified workshop. Otherwise the airbag
system may not work correctly.
- Never attempt to modify any components of
the airbag system in any way.

Child safety
Child safety
Important information
Introduction
The rear seat is generally the safest place in a
collision .
The physical principles of what happens when
your vehicle is in a crash apply also to children
¢ page 131, What happens to occupants not
wearing safety belts? .
But unlike adults their
muscles and bones are not fu lly deve loped . In
many respects ch ildren are at greater risk of ser i­
ous injury in crashes than adults.
Because children's bodies are not fu lly devel­
oped, they requ ire restraint systems especially
des igned for their size, we ight, and body struc­
ture. Many countries and all states of the United
S tates and p rovinces of Canada have laws requir­
ing the use of approved child restraint systems
for infants and small children.
I n a frontal crash at a speed of 20-35 mph
(30-56 km/h) the forces acting on a 13-pound
(6 kg) infant will be more than 20 times the
weight of the child. This means the weight of th e
child would suddenly be more than 260 pounds
(120 kg) . Under these conditions, only an appro ­
priate child restraint properly used can reduce
the risk of serious injury. Child restraints must be
used properly to be effective . Used improperly,
they can increase the risk of serious injury in an
accident.
Consult the child safety seat manufacturer's in ­
structions to be sure the seat is right for your
child's size¢
page 161, Important safety in­
structions for using child safety seats.
Please be
sure to read and heed all of the important infor­
mation and WARN INGS about ch ild safety, Ad­
vanced Airbags, and the installation of child re­
straints in this chapter.
There is a lot you need to know about the Ad­
vanced Airbags in you r vehicle and how they work
when infants and children in child restraints are
on the front passenger seat . Because of the large
amount of important information, we cannot re­
peat it all here. We urge you to read the detailed
158
information in this owner 's manual about airbags
and the Advanced Airbag System in your vehicle
and the very important information about trans­
porting children on the front passenger seat.
Please be sure to heed the WARNINGS - they are
extremely important for your safety and the safe ­
ty of your passengers, especially infants and small chi ldren .
&_ WARNING
-Accident statistics have shown that children
are generally safer in the rear seat area than
in the front seating position. Always restrain
any child age 12 and under in the rear.
- All vehicle occupants and especially children
m ust be restrained properly whenever riding
in a vehicle. An unrestrained or improperly
restrained child cou ld be injured by striking
the interior or by being ejected from the ve­ hicle during a sudden maneuver or impact.
An unrestrained or improperly restrained
child is also at greater r isk of injury or death
through contact w ith an inflating airbag .
- A suitable ch ild restraint properly installed
and used at one of the rear seating positions
provides the highest degree of protect ion
for infants and small children in most acci­
dent sit uat ions.
&_ WARNING
Children on the front seat of any car even with
Advanced Airbags can be ser iously 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 ch ild safety
seat or infant carrier with great force and
w ill smash the child safety seat and child
aga inst the backrest, center armrest or
door.
-Always install rearward-facing child safety
seats on the rear seat.
- If you must install a rearward facing child
safety seat on the front passenger seat in
