Repair, care and disposal of the airbags
Parts of the airbag system are insta lled at many different places on
yo ur Audi. Ins tal li n g, r em oving, s ervicing o r rep airi ng a part in an area of the vehicle can damage a part of an airbag system and
p revent that sys tem from wo rking pr operly in a c ollisi on.
Th ere are some important th ings you have to know to ma ke sure
that the effectiveness of the system will not be impai red and that
discarded co mponents do no t cause i njury or po llute the enviro n­
ment.
& WARNING
Improper care , servicing and repair procedures can increase the
risk of personal injury and death by preventing an airbag from
deploying when needed or deploying an airbag unexpectedly :
• Never cover , obstruct , or change the steering wheel horn pad
or airbag cover or the instrument panel or modify them in any way.
• Never atta ch any objects su ch as cup holders or telephone
mountings to the surfaces covering the airbag units .
• For cleaning the horn pad or instrument panel , use only a soft ,
dry cloth or one moistened with plain water . Solvents or cleaners
could damage the airbag cover or change the stiffness or strength
of the material so that the airbag cannot deploy and protect prop ­
erly .
• Never repair , adjust, or change any parts of the airbag system .
• All work on the steering wheel , instrument panel , front seats or
electrical system (including the installation of audio equipment ,
cellular telephones and CB radios , etc .I must be performed by a
qualified technician who has the train ing and special equipment
necessary .
• For any work on the airbag system, we strongly recommend
that you see your author ized Audi dealer or qualified workshop .
• Never modify the front bumper or parts of the vehicle body .
• Always make sure that the side airbag can inflate without inter-
ference :

& WARNING
An inflating knee airbag can cause serious injury. Wearing safety
belts incorrectly and improper seating positions increase the risk
of serious personal injury and death whenever a vehicle is being
used .
• The airbag system cannot protect you properly if you are
seated too clo se to any of the airbag locations. When adjusting
& WARNING (continued)
their seat positions , it is important that both the driver and the
front passenger keep their upper bodies and knees at the
follow ing min imum safe distances :
- 1 O inches (25 cm) between the chest and the steering
wheel /instrument panel .
- 4 inches (10 cm) between the knees and the lower part of the instrument panel.
• The risk of personal injury increases if you lean forward or to
the side, or if the seat is improperly positioned and you are not
wearing your safety belt. The r isk increases even more should the
airbag deploy .
• Always make sure that the knee airbag can inflate without
interference . Objects between yourself and the airbag can
increase the risk of injury in an accident by interfering w ith the
way the airbag deploys or by being pushed into you as the a irbag
deploys.
-No persons (children) or animals should ride in the footwell
in front of the passenger seat . If the airbag deploys , this can
result in serious or fatal injuries .
- No objects of any kind should be carried in the footwell area
in front of the driver's or passenger's seat. Bulky objects (shop­
ping bags , for example) can hamper or prevent proper deploy ­
ment of the airb ag. Sm all objects can be thrown through the
vehicle if the airbag deploys and injure you or your passengers .
• Make sure there are no cracks , deep scratches or other damage
in the area of the instrument panel where the knee airbags are
located .
• If children are incorrectly seated , their risk of injury increases in
the case of an accident

• in side collisions when the acceleration measured by the sensor
is too low
• in front -end collisions
• in rear -end collisions
• in rollovers.
In some types of accidents the front airbags, side curtain airbags
and side airbags may be triggered together.
& WARNING
• Safety belts and the airbag system will only provide protection
when occupants are in the proper seating position
~ page 240.
• If the airbag indicator light comes on when the vehicle is being
used , have the system inspected immediately by your authorized
Audi dealer . The airbag may not work properly when the vehicle
acceleration in a side collision is high enough to activate the
airbag .•
How supplemental side airbags work
Side airbags deploy instantly and can help reduce the risk
of upper torso injuries for occupants who are properly
restrained.
Fig. 239 Inflated side
airbags on left side of
vehicle, rear s ide
airbag
When the system is triggered, the airbag is filled with propellant gas
and breaks through a seam in the seat surface area marked
"AIRBAG" . It expands between the side trim panel and the
passenger. In order to he lp provide this additional protection, the
side airbag must inflate within a fraction of a second at very high
speed and with 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 applies especially to children~
page 245, "Child Safety".
Supplem ental side airbags inflate between the occupant and the
door panel on the side of the vehic le that is struck in certain side
collision~ fig. 239.
Although they are not a soft pillow, they can "cushion" the impact and in this way they can he lp to reduce the risk of injury to the upper
part of the body.
A fine dust may develop when the airbag deploys. This is normal
and does not mean there is a fire in the vehicle. •
Important safety instructions on the side
airbag system
Airbags are only supplemental restraints. Always prop­
erly wear safety belts and ride in a proper seating posi­
tion .
There is a lot that you and your passengers must know and act
accordingly to help the safety belts and airbags do their job to
provide supplementa l protection.
& WARNING
An inflating side airbag can cause serious or fatal injury. Improp ­
erly wearing safety belts and improper seating positions increase
the risk of serious personal injury and death whenever a vehicle is
being used . _.,

• In order to reduce the risk of injury when the supplemental side
airbag inflates:
-Always sit in an upright position and never lean against the
area where the supplemental side airbag is located .
- Never let a child or anyone else rest their head against the
side trim panel in the area where the supplemental side airbag
inflates.
- 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 without inter ­
ference.
-Never install seat covers or replacement upholstery over the
front seat backs that have not been specifically approved by

- Never use additional seat cushions that cover the areas
where the side airbags deploy .
- Damage to the original seat covers or to the seam in the area
of the side airbag module must always be repaired immedi­
ately by an authorized Audi dealer .
• Objects between you and the airbag can increase the risk of
injury in an accident by interfering with the way the airbag unfolds
or by being pushed into you as the airbag inflates .
- Never place 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 projec­
tiles and cause injury when the supplemental side airbag deploys.

& WARNING (continued)
-Never carry any objects or pets in the deployment space
between them and the airbags or allow children or other
passengers 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 with side airbag deployment and 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 airbag system can only be triggered once. If the airbag has
been triggered, the system must be replaced by an authorized
Audi dealership.
• Damage (cracks, deep scratches etc.I to the original seat covers
or to the seam in the area of the side airbag module must always
be repaired immediately by an authorized Audi dealer.
• If children are seated improperly, their risk of injury increases
in the case of an accident=>
page 245, "Child Safety".
• Never attempt to modify any components of the airbag system
in any way.
• In a side collision, side airbags will not function properly if
sensors cannot correctly measure increasing air pressure inside
the doors when air escapes through larger, unclosed openings in
the door panel.
-Never drive with interior door trim panels removed.
- Never drive when parts have been removed from the inside
door panel and the openings they leave have not been properly
closed.
- 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 in the

The side curtain airbags inflate between the occupant and the
windows on the side of the vehicle that is struck in a side collision
=> fig. 241 .
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 to help
provide this additional protection, the side curtain airbag must
inf late within the blink of an eye at very high speed and with great
f orce . The side curtain airbag could injure you if your seating posi­
tion is not proper or upright or if items are located in the area where
the supplementa l side curtain airbag inflates . This applies espe ­
cially to children=>

Child Safety
Important things to know
Introduction
The rear seat is generally the safes t place in a collision.
The p hysica l pr inciples of what happens when you r veh ic le is in a
crash apply also to children=>
page 213, "What happens to occu ­
pa nts not wearing safety bel ts?" . But un like adults and teenagers,
their musc les and bones are not fully developed. In many respects
children a re a t greater ris k of serious injury in cras hes than a dults .
B ecause chi ldren's bodies are no t fully deve loped, they require
restraint systems especial ly designed for their size, weight, and
body structu re. Ma ny countries and al l sta tes of the U nited States
and provinces of Canada have laws requiring the use of approved
chil d restraint sys te m s for infa nts and smal l children .
I n a frontal crash at a speed of 20 -35 mph (30 -56 km/h) the forces
acting on a 13-pou nd (6 kg) infant wi ll be mo re than 20 times the
weight of the child. This means the weight of the child would
suddenly be more than 260 pounds ( 120 kg). Under these condi ­
t ions, only an appropriate child restraint proper ly used can reduce
the risk of serious injury. Child restraints, like adult safety belts,
must be used properly t o be effective. Used impro perly, they can
increase the risk of serious injury in an accident.
Co nsul t the c hild safety seat man ufacture r's ins truc tions to be su re
the seat is right for your child's size=>
page 248, "Important safety
instructions for using child safety seats" . Please be sure to read and
heed a ll of the important information and WARNI NGS about child
safety, Advanced Airbags, and the insta llation of child restraints in
this chapter.
T here is a lot you need to know about the Advanced Airbags in your
veh ic le and how they work whe n inf an ts and ch ild ren in c hild
restraints are on the front passenger seat. Because of the large
Controls and equip­ ment Safety first Vehicle operation amoun
t of important informat ion, we cannot repeat it all here. We
urge you to read the detai led information in this owner's manua l
about a irbags and the Advanced Airbag Sys tem in your ve hic le and
the very important information about transporting children on the
fr ont passenger sea t. Please b e sure to hee d th e WAR NINGS -th ey
are extreme ly important for your safety and the safety of your
p asse ngers, es pecia lly inf ant s and s mall ch ildren .
& 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 o ccupants and especially children must be
restrained properly whenever riding in a vehicle . An unrestrained
or improperly restrained child could be injured by striking the inte­
rior or by being ejected from the vehicle during a sudden
maneuver o r impact . An unrestrained or improperly restrained
c hild is also at greater risk of injury or death through conta ct with
an inflating a irbag .
• A suitable child restraint properly installed and used at one of
the rear seating positions provides the highest degree of protec­
tion for infants and small children in most ac cident situations .
& WARNING
Children on the front seat of any car even with Advanced Airb ag s
c an be seriously injured or even killed when an airbag inflates . A
child in a rearward -fa cing child safety seat installed on the front
pas senger seat will be seriously injured and can be killed if the
front airbag inflates.
• The inflating airbag will hit the ch ild safety seat or infant
carrier with great force and will sma sh the child safety seat and
child against the backrest , center arm rest , or door. •
