passenger seat is checked by the electronic con
tro l unit when the ignition is on . The control unit
monitors the Advanced A irbag System and turns
the airbag indicator light on when a malfunct ion
in the system components is detected. The func
tion of the airbag indicator l ight is descr ibed in
greater detai l below . Because the front passen
ge r seat conta ins important parts of the Ad
vanced A irbag System, you must take care to p re
ve nt i t from being damaged. Damage to the seat
may prevent the Advanced Airbag for the fron t
passenger seat from doing its job in a crash.
The front Advanced Airbag System consists
of the following :
-Crash sensors in the front of the vehicle that
measure vehicle acceleration/deceleration to
provide information to the Advanced Airbag
System a bout the severity of the crash.
- An e lectronic control unit, with integrated
crash sensors for front and side impacts. The
control unit "decides" whether to fire the front
airbags based on the information received from
the crash sensors. The control unit a lso "de
c ides" whether the safety belt pretens ioners
should be activated .
- An Advanced Airbag with gas generator and
control
valve for the driver ins ide the steer ing
wheel hub .
- An Advanced Airbag with gas generator and contro l
valve inside the instrument pa nel for
the front passenger.
- A weig ht-sensing mat under the upho lstery
padd ing of the front passenge r seat cushion
t h at meas ures the total weight on the seat. The
i nforma tion registered is sent continuously to
the e lectron ic cont rol unit to reg ulate dep loy
ment o f the front Adv a need A irbag on the pas
senger side .
- An airbag monito ring system and indicator
li ght in the instrument cluster

-A senso r in eac h front sea t registers the dis
tance between the respective seat and the
steering wheel or instrument pane l. The infor

electronic control unit to regulate deployment
of the front Adva need A irbags.

damaged, preventing them and the airbag
system from working properly.
- Never place seat covers or rep lacement up
holstery that have not been specifically ap
proved by Audi on the front seats .
- Seat covers can prevent the Advanced Air
bag System from recognizing child re
straints or occupants on the front passenger
seat and prevent the side a irbag in the seat
backrest from deploying properly.
- Never use cush ions, pillows, blankets or
similar items on the front passenger seat.
The add it ional padding will prevent the
weight-sens ing mat in the seat from acc u
rately reg istering the ch ild restraint or per
son on the seat and prevent the Advanced

- If you must use a child rest raint on the front
passenge r seat and the child restraint man
ufacturer 's instructions require the use of a
towel, foam cushion or something else to properly position the ch ild restraint, make
certain that the

How the Advanced Airbag System
components work together
The front Advanced Airbag System and the side
airbags supplement the protection offered by the
front three-po int safety belts with pretensioners
and load limiters and the adjustable head re
stra ints to help reduce the r isk of injury in a wide
range of accident and crash situations. Be sure to read the important informa tion about safety and
heed the WARN INGS in t his chapter.
Deployment of the Advanced Airbag System and
the act ivat ion of the safety belt pretensioners de
pend on the deceleration measu red by the crash
sensors and regis tered by the electronic control
unit. Crash severity depends on speed and decel-
156 eration as well as the mass and stiffness of the
vehicle or object involved in the crash
.
On the passenger side, regard less of safety be lt
u se, the airbag will be turned off if the weight on
the passenger seat is less than the amount pro
grammed in the electronic control unit . The front
airbag on the passenger side will also be turned
off if one of the child safety seats that has been certified under Federal Motor Vehicle Safety
Standard 208 has been recogn ized on the seat .

some important things to know.
A WARNING
To reduce the ris k of injury when an airbag in
f lates, always wea r safety belts properly.
- If you are un restrained, leaning forward, sit
ting sideways or out of position i n any way,
your risk of injury is much higher.
- You will a lso receive serious injuries and
could even be killed if you are up against the
airbag or too close to it when it inflates -
even with an Advanced Airbag

Th e fr ont a irbags are designed to provide addi
tional protection for the chest and face of the
driver and the front seat passenger when:
- sa fety belts are worn prope rly,
- the seats have been positioned so that the oc-
c u pan t is prope rly sea ted as far as possible
from the airbag,
- and the head restra ints have been p roperly ad-
j u ste d.
Because airbags inflate in the blink of a n eye w ith
g reat fo rce, th ings you have on your lap or have
p laced on the seat cou ld become dangerous pro
jectiles , a nd be p ushed in to you if the ai rbag in
flates.
When an a irbag deploys, fine dust is re leased.
This is normal and is not caused by a fire in the
ve hicl e. Thi s dust is made up mostly of a powder
used to lubricate the airbags as they deploy. It
could irritate skin.
It is important to remember that whi le the s up
p lemental airbag system is des igned to reduce
the likel ihood of ser ious injuries, o ther i njur ies,
for example swelling, bruising and minor abra
sions, can a lso happen when airbags in flate . Ai r
bags do not protect the arms or the lower parts
of the body. Front airbags only supplement the
three po int safety belts in some frontal co llisions
in which the ve hicle decelerat io n is high enough
to deploy the airbags .
F ront airbag s will not deploy:
- if the ignit ion is switched off when a crash oc-
curs,
- in s ide collisions,
- in rear-end collisions,
- in rollove rs,
- when the crash decelerat io n meas ured by the
airbag system is less than the minimum thresh
o ld needed for airbag deployment as registered
by the e lectronic contro l unit.
The front passenger airbag will also not d eploy:
- when the front passenger seat is not o ccu pied,
- when the we igh t on the fron t passenge r seat as
sensed by t he Advanced A irbag Sys tem indi-
Airb ag sys tem
cates that the front a irbag on the passenger
side has to be t urned off by the e lectronic con
trol unit (the
PASSENGER AIR BAG OFF light
comes on and stays on).
A WARNING
Sitting in the wrong position can increase the r isk of ser ious injury in crashes .
- To reduce the r isk of injury when the airbags
inflate, the drive r and passenge rs must al
ways sit in an up right posit ion, m ust not
lean aga inst or place any part of their body
too close to the area where the airbags are
lo cated.
- Occupants who are unbelted, out of posit ion
or too close to the airbag can be serio usly
in jur ed by an air bag as it unfolds with g reat
for ce in the blink ofan eye
r=>page 149.
A WARNING
-A child in a rearward-fa cing child safety se at
i nsta lled on the front passenger seat will be
se riously inju red and can be k illed if the front
airbag inflates -even with an Advanced Airbag
System.
- The inflating airbag will h it the ch ild safety
seat or in fant ca rr ier with great force and
will smash the child safety seat and child aga inst the backrest, center armrest, door
or roof.
- Always install rear-fac ing child safety seats
on the rear seat.
- If you must install a rearward facing child
safety seat on the front passenger seat be
cause of excep tional circumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immedia tely insta ll
the rea r-facing child safe ty se at in a rear
seating posi tion and have the airbag system
inspecte d by your au thorized Audi dealer.
A WARNING

Objects between you and the air bag will in -
crease the risk of injury in a crash by interfer
i ng with the way the airbag unfolds or by be
i ng p ushed into you as the airbag inflates.
157
Airbag syste m
-Never h old things i n your hands or on your
lap whe n the vehicle is in use.
- Never transport items on or in the area of
the front passenger seat. Objects could move into the area of the front airbags dur
ing brak ing or other sudden maneuver and
become dangerous projectiles that can
ca use serious personal injury if the a irbags
inflate.
- Never place or attach accessor ies or other
objects (such as cupholders, telephone
brackets, large, heavy o r bulky objects) on
the doors, over or nea r the area marked
"AIRBAG" on the steering wheel, instru
ment pane l, seat backrests or between
those areas and yourself. These objects could cause injury in a c rash, especially
when the airbags inflate.
- Never recline the front passenger's seat to
transport objects. Items can also move into
the area of the side airbag or the front a ir
bag dur ing braking or in a sudden maneu
ver. Objects near the airbags can become projectiles and cause injury, particularly
when the seat is reclined.
A WARNING
The fine dust created when airbags deploy can
cause breathing p roblems for people w ith a
his to ry of asthma or o ther b reathing condi
tions .
- T o reduce the risk of brea thing problems,
those w ith asthma or o ther respiratory con
ditions should get fresh air right away by
getting out of the vehicle or o pening win
dows or doors.
- If you are in a collision in which airbags de
ploy, wash your hands and face with mild
soap and water before eat ing.
- Be careful not to get the dust into your eyes,
or into any cuts or scratches.
- If the resid ue should get into your eyes,
flush them with water .

_& WARNING
I f the front a irbag inflates, a ch ild without a
chi ld restraint, in a rea rward-facing chi ld safe
ty seat or in a forward -fac ing chi ld restrain t
that has not been proper ly ins talled will be
seriously injured and can be killed .
- Even tho ugh you r vehicle is equipped with
an Advanced A irbag System, make certain
that a ll children, espec ia lly 12 years and
younger, always ride on the back seat prop erly restrained for their age and size.
- Always install forward or rear-facing child
safety seats on the rear seat -even with an
Advanced A irbag System.
- If you must insta ll a rearward-facing child
safety seat on the front passenger seat be
cause of exceptional circumstances and the
PA SSEN GER AIR BA G OFF light does not
appear and stay on, immediately install the
rear-facing child safety seat in a rear seat ing
position and have t he a irbag system in
spected by yo ur autho rized Aud i dea le r.
- A t ight tether or other strap on a rearward
facing chi ld restraint attached to the front
passenger sea t can put too much pressure
on the weight-sensing mat in the seat and
register more weight than is actually on the
seat. The heavier weight registered can
make the system work as though an adu lt
were on the seat and deploy the Advanced
Airbag when it must be suppressed causing
serious or even fatal injury to the child.
- If, in exceptional circumstances, you must
install a forward-facing child restraint on
the front passenger seat, always move the
seat into its rearmost position in the seat 's
fore and aft ad justment range, as far away
from the airbag as poss ible. The back res t
m ust be adjus ted to an upr ight position.

Repair, care and disposal of the airbags
Parts of the airbag system are installed at many
different places on your Audi. Installing, remov
ing, 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 discarded
components do not cause injury or pollute the
environment.
A WARNING
Improper care, servicing and repair proce
dures can increase the risk 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 airbag cover or the in
strument panel or modify them in any way.
- Never attach any objects such as cupholders
or telephone mountings to the surfaces cov
ering the airbag units.
Airbag system
-For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one mois
tened 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 properly.
- Never repair, adjust, or change any parts of
the airbag system.
-All work on the steering wheel, instrument panel, front seats or electrical system (in
cluding 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 au
thorized 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 interference:
- Never install seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
Audi.
- Never use additional seat cushions that
cover the areas where the side airbags in
flate.
- 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.
- 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 replacement
parts designed and approved especially for
your Audi model version. Replacement of complete airbag systems or airbag components must be performed by qualified work-
shops only. Make sure that any airbag

The s ide airbag system supp lements the safe ty
be lts and can help to reduce the risk of injury to
the driver '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 veh icle accelera tion reg istered
by the control unit is high enough . If this rate is
below the reference value programmed into the
control unit, the s ide airbags will not be tr ig
ge red, even though the car may be badly dam
aged as a result of the collision .
It is no t possib le
to define an airbag trigge ring range that w ill cov
er every possible angle of impact, since the cir
cumstances wi ll vary considerably between one
collision and another. Important factors include,
for example, the nature (hard or soft) of the im
pacting objec t, the ang le of impact , vehicle
speed , etc .

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 ore properly re
strained.

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 protect ion, the
s ide curtain a irbag must inflate withi n the blink
