vided to the airbag control unit.
- If you must use a child restraint on the front
passenger 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
PASSENGE R AIR BA G OFF

the chi ld restraint is installed on the front
passenge r seat.
- If the

install child restra int in a rea r seating posi­
t ion and have the airbag system inspected
by your Audi dealer.
A WARNING
If the front passenger seat gets wet, dry it im ­
mediately.
- If liquid soaks into the front passenger seat,
this can keep the a irbag system from work­
ing properly and may, for instance, deact i­
vate the passenger frontal airbag. If this
happens, the PA SSENGER AIR BAG OFF ~;
light will come on and stay on together with
the a irbag ind icator light

ment cluster.
- If liquid is pooled on the seat, but has not
soa ked in, this may also keep the airbag sys­
tem from wo rking properly and ca use the
passenger frontal a irbag to be enabled
(turned on), even though there is a properly
installed chi ld restraint system on t he seat.
Wet towe ls or other wet things on the seat
c u shion can have the same effect . If the
front passenger frontal airbag is turned on,
the

How the Advanced Airbag System
components work together
The front Advanced Airbag System and the side
ai rbags s upplement the protection offered by the
front three -po int safety bel ts with p retensioners
and load limiters to he lp reduce the risk of injury
in a wide range of accident and crash situations.

Be sure to read the important information about
safety and heed the WARNINGS in this chapter.
Deployment of the Advanced A irbag System and
the ac tiva tion of the sa fe ty belt pretensioners de ­
pend on the dece leration measured by the c rash
sensors and registered by the electronic contro l
u nit . Crash severity depends on speed and decel­
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
use, the front passenger frontal a irbag will be
turned off if the e lectr ica l capacitance measured
by the capacitive passenger detection system on
the front passenger seat is less than the amount
programmed in t he electron ic contro l unit . The
front passenger frontal a irbag w ill also be tur ned
off if the capaci tance measured by the system for
t h e fron t passe nger sea t equals that of a n infan t
of about one year of age in one o f the chi ld sea ts

A WARNING
To reduce the risk of injury when an airbag in­
flates, always wea r safety belts prope rly.
- If you are un restrained, leaning forward, sit­

More important things to know about front
airbags
Fig. 162 Inflated front a irbags
Safety bel ts a re important to help keep front
seat occupants in the p roper seated position so
that airbags can unfold properly and provide sup­
p lemental protection in a frontal collision.
The front airbags are designed to p rovide addi­
tional protect ion for the chest a nd face of the
d river and the front seat passenger when:
- safety belts are worn properly,
- the seats have been positioned so that the oc-
cupant is properly seated as far as possible
from the airbag .
Because airbags inflate in the blink of an eye w ith
great force, things you have on your lap or have placed on the seat cou ld become dangerous pro­
jectiles , and be pushed into you if the airbag in­
flates .
When an a irbag deploys , fine dust is released.
This is normal and is not caused by a fire in the
veh icle. Th is 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 while the sup­
p lemental a irbag system is designed to reduce
the likel ihood of ser ious injuries, o ther inj uries,
for example swe lling, b ruising and mino r abra­
sions, c an a lso happe n when airbags inflate. Ai r­
bags do not protect the arms o r the lowe r parts
of the body . Front airbags supplement the three
point safety belts only in some frontal collisions
~ in which the vehicle decelerat ion is high enough ....
~ to deploy the airbags.

Airb ag sys tem
Front a irbags will not deploy :
-if the ignition is sw itched off when a crash oc-
curs,
- in side co llisions,
- in rear-end col lisions,
- in rollovers,
- when the crash deceleration measured by the
ai rbag system is less than the m inimum thresh ­
old needed for airbag deployment as registered
by the electron ic con trol un it.
The front pa ssen ger airbag will als o not
deploy:
- when the fron t passenger seat is not occupied,
- when the e lectr ica l capacitance measured by
the capacit ive passenger detection system for
the front passenger seat ind icates that the pas­
senger side frontal airbag must be switched off
by the ele ctro nic con trol un it ( the

A WARNING
Sitting in the wrong position can increase the
risk of ser ious injury in crashes .
- To reduce the risk of injury when the airbags in flate, the driver and passengers must al ­
ways sit in an upright posit ion, m ust not
lean aga inst or place any part of their body
too close to the area where the airbags are
located.
- Occupants who are unbelted, out of positio n
or too close to the airbag can be serio usly
i nju red by an airbag as it unfolds with great
force in the blink of an eye~

A WARNING
-A child in a rearward-facing child seat ins tal­
l ed on the front passenger seat will be se ri­
ously injured a nd ca n be killed i f the front air­
bag inflates -
even with an Advanced Airbag

Airbag syste m
-Always install rear -facing child seats on the
rear seat.
- If you must install a rearward facing chi ld
seat on the front passenger seat because of
exceptional c ircumstances and the
PA SSEN ­
G ER AIR BAG OFF ~;
light does not come
on and stay on, immediately install the rear­
facing child seat in a rear seating position and have the airbag system inspected by
you r Audi dealer.
_& WARNING
Objects between you and the a irbag w ill in­
crease the risk of in jury in a crash by interfer­
ing with the way the airbag unfo lds or by be­
ing pushed into yo u as the airbag inflates.
-
- Never hold th ings in your hands or on your
lap when 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 du r­
ing brak ing or other sudden maneuver and
become dangerous projectiles that can
cause serious personal injury if the a irbags
inflate.
- Never place or attach accessor ies or other
objects (such as cup holders, te lephone
brackets, large, heavy or bulky objects) on
the doors, over or near 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 crash, espe cially
when the airbags inflate.
- Never recline the front passenge r's seat to
t ransport objects . Items can also move into
the area of the side airbag or the front air­ bag during braking or in a sudden maneu­
ver. Objects near the airbags can become projectiles and cause injury, particularly
when the seat is reclined .
- Never place or transport objects on the
front passenger seat. Objects on the front passenge r seat could cause the capac itive
sensor in t he seat to signal to airbag system
that the seat is occupied by a person when it in fact is not, or that the person on the seat
208
is heavier than he or she actually is. The
change in electric capacitance because of
such objects can cause the passenger front
airbag to be t urned on when it should be
off, or can cause the airbag to work in a way
that is different from the way it would have
wo rked without objects on the seat.
- Always make sure that there is noth ing o n
the front passenge r seat that will cause the
capacitive passenge r de tection system in
the sea t to signal to the Airbag System tha t
the seat is occup ied by a person when it is
not , or to signal that it is occupied by some­
one who is heavier than the person act ually
sitt ing on the seat. The presence of an ob­
ject 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 diffe rent from the way it would have
wo rked without the object on the seat.
- Never til t the front passenger seat backrest
forward when the vehicle is mov ing . An in­
flating airbag wi ll force t he bac krest back­
ward and can injure rear seat occup ants .
_& WARNING
The fine dus t created when airbags deploy can
cause breathing prob lems for people with a
h istory of asthma or other breathing condi ­
tions.
- To reduce the r isk of breathing problems,
those with asthma o r other respiratory con­
ditions sho uld get fresh ai r right away by
getting out of the vehicle or opening win ­
dows or doors.
- If you are in a co llision in which airbags de­
ploy, wash your hands and face with m ild
soap and water before eating.
- Be carefu l not to get the dust into your eyes,
or into any cuts or scratches .
-If the residue shou ld get into your eyes,
flush them w ith water .

Repair , care and disposal of the airbags
Parts of the a irbag system are installed at many
different places on your Audi. Installing, remov­ ing, servic ing or repa iring a part in an area of the
ve hicle can damage a part of an airbag system
and prevent that system from working properly
i n a collision .
There are some important 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
env ironment.
A WARNING
Improper care, serv icing and repai r proce­
dures can increase the r is k of personal injury
and death by preventing an airbag from de­
ploying when needed or dep loying an airbag
unexpectedly:
-
- Never cover, obstruct, or change the stee r­
ing wheel horn pad or airbag cover or the in­
strument pane l or modify them in any way.
212
- Never attach any objects s uch as c up ho lders
or telephone mountings to the surfaces cov­
ering the a irbag un its.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one mois­
tened w ith plain water. Solvents or cleaners
could damage the airbag cover or change
the st iffness or strength of the material so
that the airbag canno t deploy and p rotect
properly.
- Never repair, adjust , or change any parts of
the airbag system.
- All work on the steering wheel, inst rument
panel, front seats or e lectr ica l system ( in­
cluding the installation of a udio eq uipment,
cellular telephones and C B radios, etc.)
m ust be perfo rmed by a qualified techn ician
who has the training and specia l equipment
necessary.
- For any work on the airbag system, we strong ly recommend that you see your au­
thorized A udi dealer or qualified workshop.
- Never modify the front b umper or parts of
the vehicle body.
- Always make sure that the side a irbag can
inflate w ithout interference:
- Never install seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
A udi.
- Never use additional seat c ushions that
cover 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 mus t alway s be repaired immedi­
ate ly by an autho riz ed Au di dealer.
- The a irbag system can deploy on ly once. Af­
ter an airbag h as been deployed, i t m ust be
repla ced with new replacement parts de­
signed and approved espec ia lly for your
Audi model version . Replacement of com­
plete airbag systems or airbag components
must be perfo rmed by qua lified workshops
only. Make su re that any airbag service ac­

Airbag system
In addition to their normal safety function, safe­
ty belts help keep the driver or front passenger in
position in a frontal collision so that the airbags
can provide supplemental protection.
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 why you should
always wear your safety belt, not just because
the law requires you to do so ¢
page 189, Gener­
al notes.
Remember too, airbags will deploy only once and
only in certain k inds of accidents - your safety
belts are always there to offer protection in those
accidents in which airbags are not supposed to
deploy or when they have already deployed, for
examp le when your vehicle str ikes or is struck by
another after the first collision .
This is just one of the reasons why an airbag is
not a substitute for the safety belt. The a irbag
system works most effectively when used with
the safety belts. Therefore, always wear your
safety belts correct ly.
It is important to remember that while the sup­
p lemental knee airbag system is designed to re­
duce the likelihood of serious injuries, other inju ­
ries, for example, swe lling, bruising and minor
abrasions and friction burns can also occur when
an airbag inflates .
The knee airbag system basically consists of:
- T he electronic control module
- T wo inflatab le airbags (airbag and gas genera-
tor), one for the driver and one for the front
passenger
- The airbag warning light in the instr ument clus­
ter
The knee airbag system will not deploy:
-whe n the ignition is switched off
- in frontal collisions when the deceleration
measured by the control un it is too low
- in side collisions
- in rear-end collisions
214
- in rollovers
-in the event of a system malfunction (warning/
indicator light is on)
¢ page 15.
A WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
the proper seating position¢
page 207 .
-If the airbag indicator light¢ page 15
comes when the veh icle is being used, have
the system inspected immediately by your
authorized 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 knee airbags work
The risk of injury to the leg area con be reduced
by fully inflated knee airbags.
Fig. 165 I n flated a irbags protect ing in a fro nta l coll ision
The knee airbag system has been designed so
that the airbags for the dr iver and front passen­
ger dep loy in certain but not all fronta l collisions .
If the front airbags deploy, the knee airbags also
deploy in frontal collisions when the deployment
threshold stored in the control unit is met .
When the system deploys, the airbags fill with a
prope llant gas, and inflate between the lower
part of the instrument panel and the driver and
the lower part of the instrument panel and the
front passenger
¢page 207, fig. 162 .
Although they are not a soft pillow, they can
"cushion" the impact and in this way they can
help to reduce the risk of injury to the lower ex­
tremities.

Airbag system
the occupant sitting next to it is not seated prop­
erly. The side airbag for the front passenger seat
can be used with properly installed child re­
straints. Please be sure to read the important in­
formation and warnings whenever using a child
restraint in a vehicle: Safety belts
Qpage 189,
Airbag system Qpage 197, Child safety
c::;, page 2 21 .
The side airbag system basically consists of:
-the e lectronic control modu le and externa l side
impact sensors
- the two side airbags located in the sides of the
front backrests
- the airbag warning light in the instrument clus-
ter.
The airbag system is monitored electronically to
make certa in that it is functioning properly at all
times. Each time you turn on the ignition, the air­
bag system indicator light will come on for a few
seconds (self diagnost ics).
The side airbag system supplements the safety
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 in side impacts and on­
ly when the vehicle acceleration registered by the
control unit is high enough. If this rate is below
the reference value programmed into the control
un it, the side a irbags w ill not be triggered, even
though the car may be badly damaged as a res ult
of the collision.
It is not possible to define an air­
bag tr igger ing range that will cover every poss i­
b le ang le of impact, since the circumstances will
vary considerably between one collision and an­
other. Important factors include, for example,
the nature (hard or soft) of the impacting object,
the angle of impact, vehicle speed, etc.
Q page 217, Important safety instructions on
the side airbag system .
Aside from their normal safety function, safety
belts work to help keep the driver or front pas­
senger in pos it ion in the event of a s ide collision
so that the side a irbags can provide protection .
The airbag system is
not a subst itute for your
safety belt. Rather, it is part of the overall occu­
pant restraint system in your vehicle . Always re-
216
member that the side airbag system can only
help to protect you if you are wearing your safety
belt and wearing it properly. This is another rea­
son why you should a lways wear your safety
belts, not just because the law requires you to do
so
Q page 189, General notes.
It is important to remember that while the sup­
plemental side airbag system is designed to re­
duce the likelihood of ser ious injuries, other inju­
ries, for example, swelling, bru is in g, friction
burns and minor abrasions can also be assoc iated
with deployed side airbags. Remember too, side
airbags will dep loy only once and only in certa in
kinds of accidents - your safety belts are always
there to offer protection.
Vehicle damage, repair costs or even the lack of
vehicle damage are not necessarily an ind ication
of over -sens itive or fa iled airbag activation. In
some collisions, both front and side airbags may
inflate. Remember too, that airbags wi ll dep loy
on ly once and on ly in certain kinds of collisions -
your safety be lts are always there to offer protec­
tion in those accidents in which airbags are not
supposed to deploy or when they have already
deployed .
The side airbag system will not deploy:
-when the ignition is switched off
- in side collisions when the acceleration meas -
ured by the sensor is too low
- in front-end collisions
- in rea r-end collisions
- in rollovers .
In some types of accidents the front airbags, side
curtain airbags and side a irbags may be triggered
together .
A WARNING
-Safety belts and the airbag system will only
provide protect ion when occupants are in
the proper seating position
c::;, page 217.
- If the airbag ind icator light Qpage 15
comes when the vehicle is being used, have
the system inspected immediately by your

the airbag will inflate when it is not sup­
posed to, or wi ll not inflate when it should .

Aside from their normal safety function, safety
be lts work to help keep the d river or fron t pas­
senger in posit ion in the event of a co llision so
that the side curtain airbags can provide protec ­
tion.
The airbag system is not a s ubst itu te for yo ur
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 wear ing 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 189, General notes.
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, swelli ng, bruising, fr iction burns
and minor abrasions can also be associated with
these airbags upon deployment . Remember too,
these airbags will deploy only once and only in certa in kinds of acc idents - you r safety belts are
always there to offer protection.
The side curtain airbag system basically
consists of:
- T he elec tronic contro l module and external side
impact sensors
- T he side c urtain airbags above the front and
rea r side windows with ejection mitigation fea ­
tures
- T he airbag indicator light in the instrument
panel
The airbag system is monitored elec tronically to
make certain it is f unct ion ing properly at all
Airb ag sys tem
times. Each time you switch on the ignition, the
airbag system indicator light wi ll come on for a
few seconds (self d iagnostics).
Th e side curtain airbag is not activ ated:
- if the igni tion is sw itched off,
- in side co llisions when the accele ration meas-
ured by the sensor is too low,
- in rear-end co llisions.
A WARNING
- Safety belts an d the airbag system will only
p rovide protect ion when occup ants are in
the proper seat ing position ¢
page 44,
Seats and storage .
- If the airbag ind ic a tor light~ page 15
comes when the veh icle is being used, have
the system inspected immediately by your
authorized Audi dealer . It is possib le that
the airbag will inflate when it is not sup­
posed to, or w ill not inf late when it should.
How side curtain airbags work
Side curtain airbags con work together with side
airbags to help reduce the risk of head and upper
torso injuries for occupants who ore properly re­
strained.

bags on the left s ide
The side curtain airbags inflate between the oc­
cupant and the windows on the side of the vehi-
cle that is struck in a side collision
¢fig . 169 .
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

Airbag syste m
to help provide this additional protection, the
side curtain airbag must inflat e within th e blink
of an eye at very h igh speed and with great force .
The side curtain airbag could injure you if your 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
especia lly to children
~ page 221 .
Although they are not a soft pillow, side curtain
airbags can "cushion" the impact and in this way
they can help to reduce the risk 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 veh icle.
Important safety instructions on the side
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 a nd your passengers must
know and do to help the safety be lts and airbags
do their job to provide supp lemental protect ion.
_& 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 p lace any parts of their
bodies in the area from which the side cur­
ta in a irbag inflate.
- Always make sure that the side curtain air­
bags can inflate without interference .
- Use the built -in coat hooks on ly for light­
weight clothing. Never leave any heavy or sharp-edged objects in the pockets that may
interfere w ith airbag deployment and can
cause personal injury in a collision.
- Never use hangers to hang clothes on the hooks.
- Only use factory-installed sun shades or, if
shades installed after the veh icle leaves the
factory, use only genuine Aud i sun shades .

-Never swing the sun visors over to the side
w indows if things such as pens, garage door
openers, hands-free speakers, etc. are at­
tached to the sun visors . They could come
loose and cause serious injury if the side cur­
tain airbag inflates.
- A deploying airbag inflates in a fract ion of a
second and with great force.
- Never attach objects to the cover or in the
deployment zo ne of a s ide curtain airbag .
- The a irbag deployment zones must be kept
clear at all times . Make sure there are no
objects , pets, or other persons in the space
between any vehicle occupant and any air­
bag at any time .
- Do not attach any accessories to the doors .
_& WARNING
-The a irbag system can deploy on ly once . If
the airbag has been trigge red, the system
m ust be rep laced by an authorized A udi
dea le r o r qualified workshop.
- Always have wo rk invo lv ing the side curtain
airbag system, remova l and installat ion of
the airbag components, or other repairs
performed by a q ualified dealership. Other­
wise the airbag system may not work cor­
rectly .
- Never attempt to mod ify any components of
the airbag system in any way .
