A WARNING
If t he front airbag inflates, a ch ild without
a child restra int, in a rearward-facing child
safety seat or in a forward-facing child re
straint that has not been properly insta lled
w ill be seriously injured and can be k illed.
- Even though your veh icle is equipped
with an Advanced Airbag System, make c ertain that a ll children, especially 12
years and younger, a lways ride on the
back seat properly restrained for their
age and size.
- Always instal l forwa rd or rear-facing
child safety seats on the rear seat -even
with an Advanced Airbag System.
- If you must install a rearward -fac ing
child safety seat on the front passenger
seat because of exceptional circ umstan
ces and the

- A tight tether or other strap on a rear
wa rd-facing child restra int attached to
the front passenger seat can put too much pressure on the weight-sens ing
mat in the seat and register mo re weight
than is ac tually on the seat. The heavier
weight registe red can make the system
work as though an adu lt were on the seat
and dep loy the Advanced Airbag when it
must be suppressed caus ing serious or
even fatal injury to the child.
- If, in exceptional circumstances, you
must install a forward-facing child re

Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different places o n your Aud i. Insta lling,
removing, servicing or repa iring a part in an
area of the veh icle can damage a part of an
airbag system and p revent that system from
working p roperly in a coll is io n.
There are some important t hings you have to
know to make sure that the effectiveness of
the system w ill not be impaired and that dis
ca rded components do not cause inju ry or pol
lute the environmen t.
A WARNING
Imprope r care, serv ic ing and repair p roce
dur es can increase the risk of personal in
ju ry and death by prevent ing an a irbag
from deploying when needed or dep loying
an a irbag unexpectedly:
- Never cover, obstruct , or change the
steer ing whee l horn pad or airbag cover
or the instrument panel or mod ify them
in any way .

u..
co ,...., \!) 1.1'1 ,...., 1.1'1 ,....,
-Never attach any objects such as cu
pholders 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 de
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system.
-All work on the steering wheel, instru
ment panel, front seats or electrical sys
tem (including the installation of audio
equipment , cellular telephones and CB
radios, etc.) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work
shop.
- Never modify the front bumper or parts
of the vehicle body .
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace
ment upholstery over the front seat backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can be activated only
once. After an airbag has inflated, it must be replaced by an authorized Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only
once. After an airbag has been deployed,
it must be replaced with new replace-
Airbag system 145
ment parts designed and approved espe
cially for your Audi model version . Re
placement of complete airbag systems
or airbag components must be per
formed by qualified workshops only. Make sure that any airbag service action
is entered in your Audi Warranty
& Main
tenance booklet under
AIRBAG REPLACE
MENT RECORD.
- In accidents when an airbag is deployed,
the vehicle battery separates the alterna
tor and the starter from the vehicle elec
trical system for safety reasons with a pyrotechnic circuit interrupter.
- Work on the pyrotechnic circuit inter
rupter must only be performed by a
qualified dealer -risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre
cautions must be followed.
@ For the sake of the environment
Undeployed airbag modules and preten
sioners might be classified as Perchlorate
Material -special handling may apply, see
www .dtsc.ca.gov/hazardouswaste/per-
ch lorate. When the vehicle or parts of the
restraint system including airbag modules
safety belts with pretensioners are scrap
ped, all applicable laws and regulations
must be observed. 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
change the way that the Advanced Airbag Sys
tem performs in a crash. For example, using
tire-rim combinations not approved by Audi ,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag
sensors and sent to the electronic control unit. Some suspension changes can, for
•
•
Page 148 of 284

146 Airbag system
example, increase the force levels measured
by the sensors and make the airbag system
deploy in crashes in which it would not deploy if the changes had not been made. Other
kinds of changes may reduce the force levels
measured by the sensors and prevent the air
bag from deploying when it should.
A WARNING ,.
Changing the vehicle's suspension includ
ing use of unapproved tire-rim combina
tions can change Advanced Airbag per
formance and increase the risk of serious
personal injury in a crash.
- Never install suspension components
that do not have the same performance
characteristics as the components origi
nally installed on your vehicle.
- Never use tire-rim combinations that have not been approved by Audi.
~ 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 con
trol module and prevent the Advanced Air
bag System from working properly .
- Always make sure that nothing can inter-
fere with the safety belt buckles and that
they are not obstructed.
Knee airbags
Description of knee a irbags
Applies to vehicles: with knee airbags
The knee airbag system can provide supple
mental protection to properly restrained
front seat occupants .
Fig. 153 Driver 's knee airbag
The driver knee airbag is in the instrument
panel underneath the steering wheel
¢ fig. 153, the knee airbag for the passenger
is at about the same height in the instrument
panel underneath the glove compartment.
The knee airbag offers additional protection
to the driver 's and passenger's knees and up
per and lower thigh areas and supplements
the protection provided by the safety belts.
If the front airbags deploy, the knee airbags
also dep loy in frontal collisions when the de
ployment threshold stored in the control unit
is met
¢ page 140, More important things to
know abou t front airbags .
In addition to their normal safety function,
safety belts help keep the driver or front pas
senger in position in a frontal collision so that
the airbags can provide supplemental protec
tion.
The airbag system is not a substitute for your
safety belt . Rather, it is part of the overall oc
cupant restraint system in your vehicle. Al
ways remember 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

Remember too, airbags will deploy only once
and only in certain kinds of accidents -your
safety belts are a lways there to offer protec
tion in those acc idents in which airbags are
not supposed to deploy or when they have al
ready deployed, for example when your vehi
cle str ikes or is struck by another afte r the
fi rst coll is ion.
This is just one of the reasons why an a irbag is
not a substitute for the safety belt . The airbag
system works most effectively when used with
the safety belts . Therefore, always wear your
safety bel ts correctly .
It is important to remember that while the

The risk of injury to the leg area can be re
duced by fully deployed knee airbags.
Fi g. 154 In flated a irbags protect ing in a fronta l co lli·
s ion
The knee airbag system has been designed so
that the airbags for the driver and front pas
senger deploy in certain but not all frontal
collisions.
If the front airbags dep loy, the knee airbags
also dep loy in frontal co llisions when the de
ployment threshold stored in the control unit
is met.
When the system deploys, the ai rbags fill
with a propellant gas, and inflate between the l ower part of the instrument pane l and the
driver and t he lower part of the instrument

Important safety instructions on the
knee airbag system
Applies to vehicles: with knee airbags
Airbags are only supplemental restraints. Al
ways wear safety belts correctly 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
a ir bags to provide supplemental protection .
A WARNING
An inflating knee airbag can cause serious
injury. Wearing safety belts incorrectly and
improper seating positions increase the
r isk of serious personal injury and death
whenever a vehicle is being used.
- The knee airbag system cannot protect
you properly if you are seated too close
to any of the airbag locations. When ad
justing their seat positions, it is impor
tant that both the driver and the front
passenger keep their upper bodies and
knees at the following minimum safe
distances:
- at least 10 inches (25 cm) between the
chest and the steering wheel/instru
ment panel.
- at least 4 inches (10 cm) between the
knees and the lower part of the instru
ment panel.
- T he 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 risk in
creases even more should the airbag de
ploy.
-Always make sure that the knee airbag
can inflate without interference. Objects
between you and the airbag can increase
the risk of injury in an accident by inter
fering with the way the airbag deploys or by being
pushed into you as the airbag
deploys.
- Never let anybody, especially children
o r anima ls ride in the footwell in front
of the passenger seat. If the airbag de
ploys, this can result in serious or fatal
injuries.
- Never carry objects of any kind in the
footwell area in front of the dr iver's or
passenger's seat. Bulky objects (shop
ping bags, for example) can interfere
with or prevent proper deployment of
the airbag. Small objects can be
thrown through the vehicle if the air bag deploys and injure you or your pas
sengers.
- Make sure there are no cracks, deep
scratches or other damage in the area of
the instrument panel where the knee air
bags are located.
- If ch ildren are incorrectly seated, their
risk of injury increases in a collision

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
Fig. 155 Sid e airbag location in the driver's seat
The side airbags are located in the sides of the
front seat backrests¢
fig. 155. They are iden
tified by the word "AIRBAG".
The side airbag system basically consists of:
-the electronic contro l module and external
side impact sensors ..,.

u..
co ,...., \!) 1.1'1 ,...., 1.1'1 ,....,
-the two side airbags located in the sides of
the front backrests
- the airbag warning light in the instrument
cluster.
The airbag system is monitored elect ron ica lly
to make certain that it is functioning prope rly
at all times . Each time you turn on the igni
tion, the airbag system indicator light will
come on for a few seconds (self diagnostics) .
The s ide a irb ag system supplements the safe
ty belts and can help to reduce the risk of in
jury to the drive r's and front passenger's up
per torso on the side of the vehicle that is
struck in a side co llision. The airbag deploys
only in s ide impacts and only when the vehicle
accelera tion regis tered by the con trol unit is
h igh enough . If this rate is below the refer
ence va lue programmed into the control un it,
the side airbags will not be triggered , even
though the ca r may be badly damaged as a re
sult of the collision.
It is not possible to de
fine an a irbag trigger ing range that will cover
every possible angle of impact, since the cir
cumstances wi ll vary considerably between
one co llision and another. Important factors
include, for examp le, the nature (hard or soft)
of the impacting object, the angle of impact,
veh icle speed, etc .
c=;, page 1 SO, Important
safety instructions on the side airbag system .
Aside from their normal safety function, sa fe
ty belts work to he lp keep the driver or front
passenger in posit ion in the event of a side
coll is ion so that the side a irbags can provide
p rotection.
T he airbag system is
not a substitute for your
safety belt . Rather, it is pa rt of the overall oc
cupa nt restraint system in your veh icle. Al
ways remember that the side airbag system
can only help to p rotect you if yo u are wear ing
your safety bel t and wear ing it prope rly. This
is another reason why you sho uld a lways wear
your safety belts, not just beca use the law re
qu ires you to do so
c=;, page 123, General
notes.
It is important to remember that while the
supp lemental side airbag system is designed
A irbag system 149
to reduce the likelihood of ser ious injuries,
other injuries, for example, swelling, bruising ,
and minor abrasions can also be associated
with deployed side airbags. Remember too,
s ide airbags will dep loy only once and only in
certain kinds of accidents -your safety belts
are always there to offer p rotection .
Vehicle damage, repair costs or even the lack
of veh icle damage are not necessarily an indi
cation of over -sensitive or failed airbag activa
t ion. In some col lisions, both fro nt and side
airbags may i nflate. Remember too, that ai r
bags will deploy only once a nd only in ce rtain
ki nds of col lis ions -yo ur safe ty belts a re al
ways there to offe r protec tion in those acc i
dents i n which airbags are no t supposed to
deploy or when they have a lready deployed.
The side airbag system will not deploy:
- when t he ignit io n is tu rned off
- in side co llisions when the accele ration
meas ured by t he sensor is too low
- in front-end collisions
- in rear- end collisions
-in rollovers.
In some types of accidents t he front airbags
and side airbags may be tr iggere d together.
A WARNING
- Safety belts and the airbag system will

How supplemental side airbags work
Side airbags deploy instantly and con help re
duce the risk of upper torso injuries for occu
pants who ore properly restrained.
Fi g. 1 56 Inflated s ide airbags on left side of vehicle
When the system is triggered, the airbag is
filled with prope llant gas and breaks through
a seam in the seat surface area marked "AIR
BAG". It expands between the side trim pane l
and the passenger . In order to help provide
this additional protection, the side airbag
must inflate within a fraction of a second at
ve ry hig h speed and with great force. The sup
plemental side airbag could i njure you if your
seating position is no t proper or upr ight or if
items are located in the area where the sup
p lemental side airbag expands. This applies
especial ly to children

ty.
Supplementa l side airbags inflate between
the occupant and the door pane l on the side

Q fig . 156.
A lthough they are not a soft pillow, they can
"cushion" the impact and in th is 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 de
p loys. This is norma l and does not mean there
is a fire in the vehicle. Important safety instructions on the
side airbag system
Airbags ore only
supplemental restraints. Al
ways properly wear safe ty belts and ride in a
proper seating position.
The re is a lot that you and your passengers
must know and act accord ingly to help the
safety belts and airbags do their job to pro

A WARNING
An inflating side ai rbag can cause serious
or fata l injury. Improperly weari ng safety
belts and improper seating positions in
crease the risk of serious personal injury
and death whenever a vehicle is being
used .
- In order to reduce the risk of inj ury when
the supplemental side airbag inflates:
- Always sit in an upright posi tion and
never lean aga inst the area whe re the
