146 Airbag sys te m
Since the cir cumstances will vary considerab ly
between one collision and anot her, it is not
possib le to def ine a range of vehicle speeds
that will cover every possible k ind and angle
of impact t hat will always trigger the airbags.
Important factors include, for example, the
nature (hard or soft) of the object which the
car h its, the ang le of impact, vehicle speed,
etc. The front airbags will also not inflate in
side or rea r collisions, or in ro ll-overs.
Al ways rememb er: Airbags will deploy only
once, and only in certa in k inds of co llisions.
Your safety belts are always there to offer pro
tection in those s ituations in which airbags
a re not supposed to deploy, or when they have
a lready deployed; for example, when your ve
hicle strikes or is struck by another vehicle af
ter the first co llision.
This is just one of the reasons why an airbag is
a supplementary restraint and is not a substi
tute for a safety belt . The airbag system
works most effect ively when used with the
safety belts. Therefore, always properly wear
your safety belts¢
page 136.
A WARNING
Sitting too close to the steer ing wheel or
instrument panel will dec rease the effec
t iveness of the airbags and will increase
the risk of personal injury in a collision.
- Never sit closer than 10 inches (2S cm)
to the stee ring wheel or instrument pan
el.
- If you cannot sit more than 10 inches
( 2 5 cm) from the s teer ing whee l, investi
gate whethe r adaptive equipmen t may
be available to help you reach the pedals
and increase your seating distance from
the steering wheel.
- All veh icle occupants and especia lly chil
dren must be restrained properly when
ever riding in a vehicle. An unrestra ined
or improperly restrained child could be
injured by striking the inter ior or by be
ing ejected from the vehicle during a
sudden maneuver or impact. An unre st rained or imp roperly rest rained child is also at greater risk of injury or death
through contact with an inflating airbag.
- If you are unrestrained, leaning forward,
sitt ing s ideways or o ut of pos ition in any
way, your risk of injury is m uch h igher.
- You will a lso receive serious injuries and
could even be killed if yo u are up aga inst
the airbag or too close to it when it in
flates - even w ith an Advanced A irbag.
- To reduce the risk of injury when an a ir
bag inflates, always wear safety belts
properly ¢
page 139, Safety belts.
-Always make certain that ch ild ren age 12
or younge r always ride in the rear seat. If
children are not properly restrained, they may be severe ly inju red or killed when an
ai rbag inflates.
- Never let children ride un restrained or
improperly restrained in the vehicle. Ad
just the front sea ts prope rly.
- Never ride with the back rest reclined.
- Always sit as far as possible from the
steer ing whee l or the inst rument panel
¢pag e 127.
- Always sit upright with your back against
the backrest of your seat.
- Never p lace your feet on the instrument
panel or on the seat. Always keep both
feet on the floor in front of the seat to he lp preven t serio us in ju ries to the legs
a nd h ip s if the airbag infla te s.
- Never re cline the front passenger 's sea t
to transport ob jects. Items can a lso
move into the area of the s ide airb ag or
the front a irbag du ring bra king or in a
sudden maneuve r. Objects near the air
bags can become projectiles and cause
in jur y when an airbag inflates.
A WARNING
-Airbags that have deployed in a crash must
be replaced.
- Use on ly orig inal equipment airbags ap
proved by Audi and installed by a trained
technician who has the necessary too ls

_& WARNING
If, in exceptional circumstances, you must
install a forward or rearward-facing child
restraint on the front passenger's seat:
- Improper installation of child restraints
can reduce their effectiveness or even
prevent them from providing any protec
tion.
- An improperly installed child restraint
can interfere with the airbag as it de
ploys and seriously injure or even kill the
child - even with an Advanced Airbag
System.
- Always carefully follow the manufactur
er's instructions provided with the child
seat or carrier.
- Always make sure that there is nothing
on the front passenger seat that will
cause the capacitive passenger detection
system in the seat to signal to the Airbag
System that the seat is occupied by a person when it is not, or to signal that it
is occupied by someone who is heavier
than the person actually sitting on the
seat . The presence of additional objects
could cause the passenger front airbag
to be turned on when it should be off, or
could cause the airbag to work in a way
that is different from the way it would have worked without the object on the
seat.

st rument panel
Your vehicle is equipped with an "Advanced
Airbag System" in compliance with United
States Federal Motor Vehicle Safety Standard
(FMVSS) 208 as applicable at the time your
vehicle was manufactured. The safety belts
for the seats have "pretensioners " that help
to take slack out of the belt system. The pre
tensioners are also activated by the electronic
control unit for the airbag system.
The front safety belts also have load limiters
to help reduce the forces applied to the body
in a crash.
The airbag for the driver is in the steering
wheel hub
~ fig . 157 and the airbag for the
front passenger is in the instrument panel
¢ fig. 158. The general location of the airbags
is marked "AIRBAG".
There is a lot you need to know about the air
bags in your vehicle. We urge you to read the .,..

of a typ ica l 1 year -old, but less than the
weight of a sma ll adult, the front airbag on
the passenger side may deploy (the
PASSEN
GER AIR BAG OFF
li ght does not come on).
For exa mple , the air bag m ay depl oy if:
- a small child that is heavier than a typical 1
year-o ld child is on the front p assenger seat
(regardless of whe ther the child is in one of
the chi ld seats listed
c':> page 173),
-a ch ild who has o utgrown child rest raints is
on the front passenger seat.
If the front passenger airbag is turned off, the
PA SSENGER AIR BAG OFF light in the cente r
of the instrument panel w ill come on and stay
on.
If the front passenger airbag deploys, the Federal Standard requires the a irbag to meet
the "low risk" deployment criteria to help re
duce the risk of injury through interaction
with the airbag. " Low risk" deployment occurs
in those crashes that take place at lower de
celerations as defined in the e lectronic control
un it
c':>page 157.
Alway s remember: Even tho ugh your vehicle
is equipped with Advanced Airbags, the safest
p lace for children is properly restrained on the
back seat. Please be sure to read the impor
tant information i n the sect ions that follow
and be sure to heed a ll of the WARNINGS .
A WARNING
To reduce the risk of injury when an airbag
inf lates, a lways wear safety belts prope rly.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, your risk of injury is much higher.
- You w ill also receive serious in juries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in
fla tes -even with an Advanced Airbag
c':> page 145.
A WARNING
A child in a rearward -facing child seat in
stalled on the front passenger seat will be seriously injured and can be killed if the
front airbag inflates - even w
ith an Ad
vanced Airbag System.
- Altho ugh the Advanced Airbag System in
your veh icle is designed to turn off the
front airbag when a rearward-facing
child restraint has been installed on the
front passenge r seat, nobody can abso
lutely guarantee that dep loyment is im
possible in all con ceivable s ituations that
may h appen dur ing the usefu l life of y our
veh icle .
- T he inflating airbag will h it the ch ild seat
or infant carrier wi th grea t force and will
smash the child seat an d child against
the backrest, center armrest, doo r, or
roof.
- Always install rearward-facing chi ld re
straints on the rear seat.
- If you must install a rearward fac ing
child seat on the front passenger seat
because of exceptional circumstances
and the
PASSENGER AIR BAG OFF light
does not come on and stay on, immed i
ately insta ll the rear-facing child seat in a
rea r seat ing pos ition and have the airbag
system inspected by you r Audi dealer.
A WARNING
If, in except iona l circumstances, you must
i nsta ll a forward-facing child restraint on
the front passenge r's sea t:
- Always make sure the forward-facing
seat has been designed and ce rtified by
its manufacture r fo r u se on a fron t seat
with a passenger fron t and s ide a irbag .
- Never p ut the fo rward-facing child re
straint up agains t or ve ry near the instru

- Always move the p assenge r seat into its
rearmost pos ition in the seat's fore and
aft ad justment range, as fa r away from
the airbag as possible, before installing
the forward-facing ch ild restra int. The
backrest must be ad justed to an upright

Advanced Airbag System components
The front passenger seat in your vehicle has a
l ot of very important parts of the Advanced
Ai rbag System in it. These parts incl ude the
capacitive passenger detect ion system, wir
i n g, brackets, and more . The control unit
monitors the system o n the front passenger
seat when the ign ition is switched on and
turns the airbag indicator light on when a
malfunct ion in the one of the system compo
nents is detected ¢
page 158 . Because the
fro nt passenger seat contains important pa rts
of the Advanced Airbag System, you must
t ake care to p reven t it from being damaged.
D amage to the seat may preven t the Ad
vanced A irbag System for the front passenger
seat from doing its job in a crash .
The front Advanced Airbag System
consists of the following:
-Crash sensors in the fro nt o f the veh icle that
measure vehicle acceleration/dece leration
to provide information to the Advanced Air
bag System about the severity of the crash .
- An electronic co ntrol unit, with integrated
c rash sensors for front and side impacts .
The cont ro l unit "decides" whether to fire

Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different places on your Audi. Installing,
removing, servicing or repairing a part in an
area of the vehicle can damage a part of an
airbag system and prevent that system from
working properly in a collision.
There are some important things you have to know to make sure that the effectiveness of
the system will not be impaired and that dis
carded components do not cause injury or pol lute the environment.
A WARNING
Improper care, servicing and repair proce
dures can increase the risk of personal in
jury 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 attach any objects such 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 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.
Airbag system 161
-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 deploy only once. After an airbag has been deployed, it must be replaced with new replacement
parts designed and approved especially
for your Audi model version. Replace
ment of complete airbag systems or air
bag components must be performed by
qualified workshops only . Make sure that
any airbag service action is entered in
your Audi Warranty
& Maintenance book
let under
AIRBAG REPLACEMENT RE
CORD.
- For safety reasons in severe accidents,
the alternator and starter are separated
from the vehicle battery with a pyrotech
nic circuit interrupter.
- Work on the pyrotechnic circuit inter
rupter must only be performed by a
qualified technicians who have the ex
perience, information and special tools
necessary to perform the work safely.
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre
cautions must be followed.

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 wo rks most effectively when used with
the safety belts . Therefore, always wear your
safety bel ts correctly .
It is important to remember that while the

Fi g. 162 In flated a irbags protect ing in a fronta l coll i·
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 fronta l collisions when the de
ployment th resho ld 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
panel and the front passenger

Important safety instructions on the
knee airbag system
Appl ies 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 irbags 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.
- 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 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
or animals 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 driver'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 children are incorrectly seated, their
risk of injury increases in a collision
