Airbag syste m
Always remember, a child seat or infant carrier
installed on the front seat may be struck and
knocked out of position by the rapidly inflating
passenger's airbag in a frontal collision. The air­
bag could greatly reduce the effectiveness of the
child restraint and even seriously injure the child
during inflation.
For this reason, and because the back seat is the
safest place for children -when properly restrain­
ed according to their age and size -we strongly
recommend that children always sit in the back
seat
¢ page 171, Child safety.
.8, WARNING
A child in a rearward-facing chi ld seat insta l­
led on the front passenger seat will be ser i­
ously injured and can be killed if the front air­
bag inflates -even with an Advanced Airbag
System.
- The inflating airbag will hit the child seat or
infant carrier with great force and will
smash the chi ld seat and child against the
backrest, center armrest, door or roof.
- 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
PASS EN­
G ER AIR BA G 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
yo ur Audi dealer.
- Forward-facing ch ild seats insta lled on the
front passenger's seat may interfe re with
the deployment of the airbag and cause se­
rious persona l injury to the child.
.8, WARNING
If, in except ional circumstances, you must in­
stall a forward-facing chi ld restraint on the
front passenger's seat:
- Always make sure the forward-facing se at
has been designed and certified by its man ­
ufacturer for use on a front seat with a pas­
senger front and side airbag .

-Never put the fo rward-facing child restraint
up against or very near the instrument pan­
el.
- Always move the front passenger seat to
the highest posit ion in the up and down ad­
justment range and move it back to the
rearmost posit ion in the seat's fore and aft
ad justment range, as far away from the a ir­
bag as poss ible, before install ing the for­
ward-facing chi ld restrain t.
- Always make sure that the safety be lt upper
anchorage is behind the ch ild rest raint and
not next to o r in fron t of the child rest raint
so that the safety be lt will be properly posi­
tioned.
- Ma ke sure that the

.&_ WARNING
To reduce the risk of injury when an airbag in­
flates, always wear safety belts properly.
- If you are unrestrained, leaning forward, sit­ ting s ideways or out of position in any way,
your risk of injury is much h igher.
- You will also receive serious injuries and could even be killed if you are up aga inst the
airbag or too close to it when it inflates -

.&_ WARNING
A child in a rearward-facing chi ld seat instal­
led on the front passenger seat will be ser i­
ously inju red and can be killed if the front air­
bag inflates -even with an Advanced Airbag
System.
- Although the Advanced A irbag System in
yo ur vehicle is designed to tu rn off the front
airbag when a rearwa rd -facing child re ­
straint has been insta lled on the front pas­
senger seat, nobody can absolutely g uaran­
tee that deployment is impossible in all con­
ceivable s ituations that may happen during
the useful life of your vehicle .
- The inflating a irbag w ill hit the child seat or
infant carrier w ith great force and will
smash the ch ild seat and child against the
backrest, center a rmrest, door, or roof .

.&_ WARNING ,_
If, in exceptional circumstances, you must in­
stall a forward-facing child restraint on the
front passenger's seat:
- Always make sure the forward-facing seat
has been des igned and certified by its man­
ufacturer for use on a front seat with a pas­
senger front and side airbag.
- Never put the forwa rd-facing child restraint
up against or very nea r the instrument pan­
el.
- Always move the front passenge r seat to
the highest posit ion in the up and down ad­
justmen t range and move it back to the
rearmost posit io n in the seat's fo re and aft
adjustment range, as far away from the a ir ­
bag as poss ible, before install ing the for­
ward-facing chi ld restraint.
- Always make sure that the safety be lt upper
anchorage is behind the chi ld rest raint and
not next to o r in front of the c hild restraint
so that the safety be lt will be p roper ly posi­
tioned.
- Always make sure that there is noth ing 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 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 ac tually
si tting o n the sea t. T he presence of addi­
tional objects could cause the passenger
front airbag to be turne d on when it should
be
off, or could cause the airbag to work in a
way that is d ifferent from the way it wou ld
have worked without the object on the seat.
- Make sure that the
PASSENGER AIR BAG
OFF
li ght comes on and stays on all the time
whenever the ign it ion is switched on.

parts of the Advanced Airbag System, you must
take care to prevent it from being damaged .
Damage to the seat may p revent the Advanced
Airbag System for the front passenger seat from
doing its job in a crash.
The f ront Ad vanc ed Airb ag System con sists
of the following:
- Crash sensors in the front of the vehicle that
measu re vehicle accelerat ion/ decelerat io n to
provide info rmation to the Advanced Airbag
System about the severity of the crash.
- An electro nic cont rol un it, with integrated
c rash senso rs fo r front and side impacts. The
contro l unit "decides" whether to fire the fro nt
airbags based on the information received from
the crash sensors . The contro l unit a lso "de­
c ides" whether the safety be lt pretensioners
shou ld be activated .
- An Advanced Airbag with gas generator and
contro l valve for the driver ins ide the steer ing
wheel hub.
- An Advanced Airbag with gas generator and
contro l valve inside the instrument panel for
the front passenger.
- A capac itive passenger detect ion system under­
neath the front passenger seat cover. This sys­
tem measures the electrical capac itance of the
person in the seat . T he information registered
i s sent conti nuous ly to the electro nic cont rol
unit to regulate deployment of the front Ad­
vanced Airbag on the passenge r side.
- An airbag monito ring system and indicator

-A sensor i n each front seat registers the dis­
tance between the respective seat and the
stee ring wheel or instrument pane l. The info r­
mation reg istered is sent cont in uous ly to the
electronic control unit to regulate deployment
of the front Adv a need Ai rbags.
- The
PASSENGER AIR BAG OFF light comes on
and stays on in the center of the instrument
pane l
c::> page 159, fig. 156 and tells you when
Airb ag sys tem
the front Advanced Airbag on the passenger
side has been turned off .
- A sensor in the safety belt latch for the driver
and for the front seat passenger that senses
whether that safety be lt is latched or not and
transmits this information to the electronic
control un it.
A WARNING ,-
Damage to the front passenger seat can pre-
vent the front airbag from working properly.
- Improper repair or disassembly of the front
passenger and driver seat will p revent the
Advanced Airbag System from funct io ni ng
p roper ly .
- Repairs to the front passenger seat must be pe rformed by qualified a nd p roperly trained
wo rkshop personne l.
- Never remove the front passenger or driver
seat from the vehicle .
- Never remove the upholste ry from the front
passe nger seat.
- Never d isassemble or remove parts from the
s e at o r disco nnect w ire s from it.
- Never carry sharp objects in your pockets or
put them on the seat. The capacit ive pas­
senge r de tect io n mat in the front passenger
seat will not function properly if it is punc­
tured.
- Never carry things on your lap or carry ob­
jects on the front passenge r seat. S uch ob­
jects c an influen ce the cap aci tance reg is­
t ered by the capaci tive passenger dete ction
sys tem, so that incorrect in formation is pro ­
vided to the ai rbag control un it.
- Never store i tems unde r the front p assenger
seat . Parts of the Advanced Airbag System
under the passenger seat cou ld be dam­
aged, p reventing them and the airbag sys­
tem from working proper ly.
- Never p lace seat covers or replacement up ­
holstery that have not been specifically ap­
proved by Audi on the front seats.
- Seat covers can prevent the Advanced A ir­
bag System from recognizing chi ld re­
stra ints or occupants on the front passenger
seat and preven t the side airbag in the seat
backrest from deploying prope rly .
155

Airbag syste m
-If a seat heater has been retrofitted or oth­
erwise added to the front passenger seat,
never install any child restraint system on
this seat .
- Never use cushions, pillows, blankets, or
similar items on the front passenger seat.
The additional layers prevent the capacitive
passenger detection system from accurately
measuring the capac itance of the ch ild safe­
ty seat and/or the person on the seat and
th us keep the Advanced Airbag System from
working properly .
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat heater
for child seats) on the front passenger seat if the device is connected to the 12-volt
socket or the cigarette lighter socket. Such devices can influence the capacitance reg is­
tered by the capac itive passenger detection
system, so that incorrect information is pro­
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 rest raint, make
certain that the
PASSENGER AIR BAG OFF
light comes on and stays on whenever the
child restraint is insta lled on the front pas­
senger seat.
- If the
PASSENGER AIR BAG OFF light does
not come on and stay on, immediately in­
stall child restraint in a rear seating position
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
PASSENGER AIR BAG OFF
ligh t will come on and stay on togethe r with
the airbag indicator light
II (USA models) I
156
E,I (Canada mode ls) in the instr ument clus­
ter.
- If liq uid is pooled on the seat, but has not
soaked in, th is may also keep the airbag sys­
tem from working proper ly and cause the
passenger frontal airbag to be enabled
(turned on), even though there is a p roperly
installed child restraint system on the seat.
Wet towels or other wet things on the seat
cushion can have the same effect. If the
front p assenger front al airbag is turned on,
the
PASSENGER AIR BAG OFF light ligh t
wi ll go out.
How the Advanced Airbag System
components work together
The front Advanced A irbag System and the side
airbags supp lement the protection offered by the
front th ree-point safety belts with pretens ioners
and load lim ite rs and the adj ustab le head re­
straints* to help reduce the risk of i njury in a
wide range of accident and cras h situations. Be
s ur e to read the impo rtant informat ion about
sa fety and heed the WARNINGS in this chapter.
Deployment of the Advanced A irbag System and
the activa tion of the safety belt pretens ioners de­
pend on the dece lera tion measured by the crash
senso rs and registered by the electronic contro l
unit . 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 o f safety be lt
use, the front passenger frontal airbag will be
turned off if the e lectrica l capacitance measured
by the capacitive passenger detection system on
the front passenger seat is less than the amount
programmed in t he e lectronic contro l unit . The
front passenger frontal a irbag w ill also be tur ned
off if the capacitance measured by the system for
t h e front passenger seat equals that of an infant
of about o ne yea r of age in one o f the ch ild sea ts
that was used to certify the Advanced Airbag Sys­
tem under Federa l Motor Vehicle Safety Standard
208. The
PASSENGER AIR BAG OFF light comes

A WARNING
To reduce the risk of injury when an airbag in­
flates, always wear safety belts properly.
- If you are unrestrained, lean ing forward, sit­
t ing s ideways or out of pos ition in anyway,
your risk of injury is much h igher.
- You will also receive serious injur ies and
could even be killed if you are up aga inst the
airbag or too close to it when it inflates -
even with an Advanced Airbag¢
page 147.
More important things to know about front
airbags
F ig. 155 Inflated front airbags
Safety belts are important to help keep front
seat occupants in the p roper seated position so
that a irbags can unfold properly and provide sup­
p lemental protection in a frontal collision.
The front airbags are designed to provide addi­
tional protection 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,
- and for adjustable head restraints: the head re-
straints have been properly adjusted.
Because airbags inflate in the blink of an eye with
great force, things you have on your lap or have placed on the seat could 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
Airb ag sys tem
used to lubricate the airbags as they deploy. It
could irritate skin.
It is important to remember that wh ile the sup­
plementa l airbag system is designed to red uce
the likelihood of serious injuries, other injur ies,
for example swelling, bruising and minor abra­ s ions, can also happen when airbags inflate. Air­
bags do not protect the arms or the lower parts
of the body. Front airbags supplement the three­
point safety belts on ly in some frontal collisions
in which the vehicle deceleration is high e nough
to deploy the airbags .
Fron t airb ags will not depl oy:
- if the ignition is switched off when a crash oc-
curs,
- in side collisions,
- in rear-end collisions,
- in rollovers,
- when t he crash deceleration measured by the
airbag system is less than the m in imum thresh­
old needed for airbag dep loyment as registe red
by the electronic control unit.
Th e front passenger airbag also will not
deplo y:
- when the front passenger seat is not occupied,
- when the e lectr ica l ca pacitance measured by
the capacitive passenger detection system for
the front passenger seat indicates that the pas­
senger s ide frontal a irbag must be switched off
by the electronic control unit (the
PASSENGER
AIR BAG OFF
light¢ page 159 and how they
work comes on and stays on).
A WARNING
-Sitt ing in the wrong position can increase the
risk of ser ious injury in crashes.
- To reduce the risk of injury when the airbags
inflate, the drive r and passengers must al­
ways sit in an up right posit ion, must not
lea n 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 position
or too close to the airbag can be serio usly
injured 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 instal­
led on the front passenger seat will be seri ­
ously injured and can be killed if the front air­
bag inflates - even with an Advanced Airbag
System.
- The inflating airbag will hit the child seat or
infant carrier with great force and will
smash the child seat and child against the backrest, center armrest, door or roof.
- Always install rear-facing child seats on the
rear seat.
- If you must install a rearward facing child
seat on the front passenger seat because of exceptional circumstances and the
PASSEN­
GER 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
your Audi dealer.
A WARNING
Objects between you and the airbag will in­
crease the risk of injury in a crash by interfer­
ing with the way the airbag unfolds or by be­
ing pushed into you as the airbag inflates .
- Never hold things 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 dur­
ing braking or other sudden maneuvers and
become dangerous projectiles that can
cause serious personal injury if the airbags
inflate.
- Never place or attach accessories or other
objects (such as cup holders, telephone
brackets , large, heavy or bulky objects) on
the doors, over or near the area marked "A IRBAG" on the steering wheel, instru­
ment panel, seat backrests or between
those areas and yourself. These objects
could cause injury in a crash, 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 air-
158
-
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 passenger seat could cause the capacitive
sensor in the 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
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 turned 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
worked without objects on the seat.
- 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 some­
one who is heavier than the person actually
sitting 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 different from the way it would have
worked without the object on the seat.
A WARNING
The fine dust created when airbags deploy can
cause breathing problems for people with a history of asthma or other breathing condi­
tions .
- To reduce the risk of breathing problems,
those with asthma or other respiratory con­
ditions should get fresh air right away by
getting out of the vehicle or opening 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 eating.
- Be careful not to get the dust into your eyes,
or into any cuts or scratches.
- If the residue should get into your eyes,
flush them with water .

the front passenger seat, always move the
seat into its rearmost position in the seat 's
fore and aft adjustment range , as far away
from the airbag as possible . The backrest
must be adjusted to an upright position.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the time
whenever the ignition is switched on.
_& WARNING
-If the PASSENGER AIR BAG OFF light does
not go out when an adult is sitting on the
front passenger seat after taking the steps
described above, make sure the adult is
properly seated and restrained at one of the
rear seating positions .
- Have the airbag system inspected by your
Audi dealer before transporting anyone on
the front passenger seat .
@ Tips
If the capacitive passenger detection system
determines that the front passenger seat is
empty, the frontal airbag on the passenger
side will be turned
off, and the PASSENGER
AIR BAG OFF
light will stay on.
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-
162
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 cup holders
or telephone mountings to the surfaces cov­
ering the airbag units .
- 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 deploy only once. Af­
ter an airbag has been deployed, it must be
replaced with new replacement parts de­
signed and approved especially for your
Audi model version. Replacement of com­
plete airbag systems or airbag components

page 157 , More important things to know
about front airbags .
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 prov ide supplemental protect ion .
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overall 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 soc::>
page 139, Gener­
al information .
Remember too, airbags will deploy only once and
only in certain kinds of accidents -your safety
belts are always there to offer protect ion in those
accidents in which airbags are not supposed to
deploy or when they have already deployed, for
example when your vehicle strikes or is struck by
another after the first collis ion .
This is just one of the reasons why an airbag 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 belts correct ly.
It is important to remember that whi le the sup­
p lemental knee airbag system is designed to re­
duce the likelihood of serious injuries, other inju­
ries, for example, swelling, bruising and minor
abras ions and friction burns can also occur when
an airbag inflates .
The knee airbag system basically consists of:
-The electronic control module
- Two inflatab le airbags (airbag and gas genera-
tor), one for the driver and one for the front
passenger
- The airbag indicator light in the instrument
panel
The knee airbag system will not deploy:
- when the ignition is switched off
164 - in frontal
collisions when the deceleration
measured by the contro l unit is too low
- in side collisions
- in rear-end collisions
- in rollovers
- in the event of a system malfunction (warning/
ind icator light is on)

.&_ WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
th e proper seating position
c::> page 157 .
-If the airbag indicator light c::> page 17
comes when the vehicle 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 inf late when it should.
How knee airbags work
Applies to: vehicles with knee airbags
The risk of injury to the leg area can be reduced
by fully inflated knee airbags.
Fig. 158 Inflated a irbags protect ing in a frontal coll is io n
The knee airbag system has been designed so
that the airbags for the driver and front passen­
ger dep loy in certain bu t not all fronta l co llisions.
If the front airbags deploy, the knee airbags also
deploy in frontal coll isions when the deployment
threshold stored in the control unit is met.
When the system deploys, the airbags f ill 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
