switched on and turns the airbag indicator light
on when a malfunction in the one of the system
components is detected
c::> page 265. Because
the front passenger seat contains important
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 Sy stem con sist s
of the following:
- Crash sensors in the front of the vehicle that
measu re vehicle accelerat ion/ decelerat ion to
provide information to the Advanced Airbag
System about the severity of the crash.
- An electronic cont rol unit, with integrated
c rash sensors for front and side impacts. The
contro l unit "decides" whether to fire the front
airbags based on the information received from
the crash sensors . The contro l unit also "de­
cides" whether the safety be lt pretensioners
should 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 . The information registered
i s sent conti nuously to the electron ic cont rol
unit to regulate deployment of the front Ad­
vanced Airbag on the passenge r side.
- An airbag monitoring system and indicator
li ght
mi n the instrument cluster.
- A sensor in each front seat registers the dis­
tance between the respective seat and the
stee ring wheel or instrument panel. The info r­
mation reg istered is sent contin uous ly to the
electronic control unit to regulate deployment
of the front Adv a need Airbags.

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 prevent the
Advanced Airbag System from funct ion ing
p roperly.
- Repairs to the front passenger seat must be
pe rformed by qualified and properly trained
wo rkshop personne l.
- Never remove the front passenger or driver
seat from the vehicle .
- Never remove the upholstery from the front
passe nger seat.
- Never d isassemble or remove parts from the
seat or disconnect w ires from it.
- Never carry sharp objects in your pockets or
put them on the seat. The capacit ive pas­
senger detect ion mat in the front passenger
seat will not function p roperly if it is punc­
tured.
- Never carry things on your lap or carry ob­
jects on the front passenge r seat. Such ob ­
jects ca n infl uence the capacitance reg is­
tered by the capacitive passenger detection
system, so that incorrect information is pro­
vided to the airbag control unit.
- Never store items unde r the front passenger
seat . Parts of the Advanced Airbag System
under the passenger seat could be dam­
aged, preventing them and the airbag sys­
tem from working properly.
- 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 child re­
stra ints or occupants on the front passenger
seat and prevent the side airbag in the seat
backrest from deploying properly .
- If a seat heater has been retrofitted or oth- erwise added to the front passenger seat ,

Airbag syste m
never insta ll any chi ld restraint system on
this seat .
- Never use cushions, pillows, blankets, or
similar items on the front passenger seat .
The add itional layers prevent the capacitive
passenger detection system from accurat ely
measuring the capac itance of the ch ild safe ­
ty seat and/or the person on the seat and
thus keep the Advanced Airbag System from
wor king properly.
- Never place or use any electrical device
(such as a laptop, CD player, elect ronic
games dev ice, power inverte r or seat heater
for child seats) on the front passenger seat
i f the device is conne cted 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
ufact urer 's instructions require the use of a
towel, foam cushion or something else to
prope rly position the ch ild rest raint, make
c ertain that the

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
va te the passenger frontal airbag. If this
happens, the

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 t hree-point safety belts with pretens ione rs
and load lim ite rs and the ad justab le head re­
strain ts to help reduce t he risk of injury in a wide
r ange of accident and c rash s itu ations. Be sure to
read the important info rmation abou t safety and
heed the WARNINGS in this chapter.
Deployment of the Adva nced A irbag System and
the activa tion of the safe ty belt pretensioners de­
pend on the dece lera tion measured by the crash
senso rs 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 o r object involved in the crash.
On the passenger side, regard less of safety be lt
use, the front passenger frontal airbag will be
turned off if the e lectr ica l capacitance measured
by the capaci tive passenger detection system on
the front passenger seat is less than the amount
programmed in t he e lectronic control unit . The
front passenger frontal a irbag w ill also be turned
off if the capaci tance measured by the system for
the fron t passenger seat equals that of an infant
of about one year o f age in one o f the chi ld sea ts
that was used to certify the Advanced Airbag Sys ­
tem under Federa l Moto r Vehicle Safety Standard
208. The

_& 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

0 0 M
-..:, ... m
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 the head restraints have been properly ad-
justed
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.
8 This is normal and is not caused by a fire in the
~ vehicle. Th is dust is made up mostly of a powder
co
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 serio us 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

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 ins t or place any part of their body
too close to the area where the airbags are
located.
- Occupants who are unbelted, out of posi tion
or too close to the airbag c an be serio usly

make sure the adu lt is properly seated and
restrained at one of the rear seating posi­
tions . Have the a irbag system inspected by
your author ized Audi dealer before trans­
port ing anyone on the front passenger seat.
A WARNING
f-
An a irbag system that is not functioning prop-
e rly cannot prov ide supplemental protect io n
i n a front al crash.
- I f the ai rbag ind icator light~

comes when the veh icle is being used, have
the system inspected immedia tely by your
authorized Audi dealer . It is possib le that
the airbag will inflate when it is not sup­
posed to, or will not inflate when it should.
A WARNING
If the front airbag inflates, a ch ild without a
chi ld restraint, or in a rearward-facing child
safety seat, or in a forward-fac ing child re­
stra int that has not been properly insta lled
will be seriously injured and can be killed.
- Even though your vehicle is equipped with
an Advanced A irbag System, make certain
that all children , espec ially 12 years and
younge r, always ride on the back seat p rop­
erly rest rained for the ir age and s ize .
- Always install fo rwa rd or rear-facing child
safety seats on the rear seat - even with an
Advan ced Airbag System.
- I f you must install a rea rwa rd-facing child
safety seat on the front passenger seat be­
cause of excep tional circums tances and the
PASSENGER AIR BAG OFF,;, light does not
appear and stay on, immediate ly install the
rear-facing chi ld safety seat in a rear seat ing
position and have the a irbag system in­
spected by your authori zed Aud i dea ler.
- 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 a irbag as poss ible . The back rest
m ust be adjusted to an upr ight position .

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 245, Gener­
al information.
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 indicator ligh t in the instrument
panel
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
270
- in rollovers
-in the event of a system malfunction (warning/
ind icator light is on)
¢page 33.
A WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
the proper seating position
¢page 263.
-If the airbag indicator light¢ page 33
comes when the veh icle is being used, have
the system inspected immediately by your
author ized 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. 224 In 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 263, fig. 221 .
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.

All of this takes place in the blink of an eye, so
fast that many people don't even realize that the airbags have deployed . The airbags also inflate
with a great deal of force and it is important for
occupant safety that nothing should be in their
way when they deploy .
Fully inflated airbags in comb ination with proper­
ly worn safety belts slow down and limit the oc­
cupant 's forward movement and help to reduce
the r isk of injury .
Important safety instructions on the knee
airbag system
Airbags are only supplemental restraints . Always
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 be lts and airbags
to provide s upplemental protection .
,& WARNING
An inflating knee airbag can cause ser ious in­
jury. Wearing safety bel ts incor rectly and im­
proper seating posit ions increase the r isk o f
serious personal injury and death whenever a
vehicle is being used.
- The knee airbag system cannot protect you
prope rly if you are seated too close to any of
the a irbag locat ions. When ad justing their
seat positions, it is important that both the
dr iver and the front passenger keep their
upper bod ies a nd knees at the following
min imum safe d istances:
- at least 10 inches (25 cm) between the
chest and the steering wheel/instrument
panel.
- at least 4 inc hes (10 cm) between the
knees and the lower part of the instru­
ment panel.
- The risk of persona l injury increases if you
lean forward or to the side, or if the seat is
improper ly positioned and you are not wear­
ing your safety belt. The risk increases even
more should the a irbag deploy.
- Always make sure that the knee airbag can
inflate without interference. Objects be-
Airbag sys tem
tween you and the airbag can increase the
risk of injury in an accident by interfering
wit h the way the airbag deploys or by being
pushed into yo u as the a irbag deploys.
- Never let anybo dy, especi ally children or
anima ls r ide in the footwell i n front of the
passenger seat. If the airbag deploys, this
can result in serious o r fatal in juries.
- Never carry objects of any kind in the foo t­
well area in front of the driver's or pas­
senger's seat . Bulky objects (shopp ing
bags, for example) can interfere with or
prevent proper dep loyment of the airbag.
Small objects can be thrown th rough t he
vehicle if the airbag deploys and injure you
o r your passengers.
- Make sure the re a re no cracks, deep scratch­
es o r othe r damage in the area of the inst ru­
ment panel where the knee airbags a re lo­
ca ted.
- If ch ildren are incorrectly seated, their risk
of injury inc reases in a coll is ion

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 245,
Airbag system Q page 253, Child safety
c::;, page 2 7 7.
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
- two rear side airbags*
- the airbag warning light in the inst rument 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 ign it ion, the air­
bag system indicator light will come on for a few
seconds (self diagnostics).
The side airbag system supplements the safety
be lts and can help to reduce the risk of injury to
the driver's, front and rear* passenger's upper
torso on the side of the vehicle that is struck in a
side co llision. The a irbag dep loys only in side im­
pacts and on ly when the vehicle acceleration reg­
istered by the control unit is high enough . If this
rate is below the reference value programmed in­
to the control un it, the side airbags w ill not be
tr iggered, even though the car may be badly
damaged as a result of the collision.
It is not pos­
sib le to define an a irbag tr igger ing range that
will cover every possible angle of impact, since
the circumstances will vary considerably between
one collision and another . Important factors in­
clude, for example, the nature (hard or soft) of
the impacting object, the angle of impact, vehicle
speed, etc.
Q page 2 73, Important safety in­
structions on the side airbag system.
Aside from their normal safety function, safety be lts 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-
272
pant res traint system in your vehicle . Always re­
member that the side airbag system can only
help to protect you if you are wear ing 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 c::;,
page 245, General information .
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 ing, friction
burns and minor abrasions can also be assoc iated
with deployed side airbags. Remember too, side
a irbags w ill 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 icat ion
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 deploy
on ly once and only 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 turned off
- in side co llisions 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
curta in airbags and side a irbags may be triggered
together .
&_ WARNING
-Safety belts and the airbag system will only
provide protection when occupants are in
the proper seating position
Q page 2 7 3.
- If the airbag indicato r light Q page 33
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
supposed to, or will not inflate when it
should.
How supplemental side airbags work
Side airbags deploy instantly and can help re­ duce the risk of upper torso injuries for occu­
pants who are properly restrained.
Fig. 226 Infla ted side airbags on left side of veh icle, rear
side airbag opt ional equipment
When the system is triggered, the airbag is filled
with propellant gas and breaks through a seam in
the seat surface area.
It expands between the
side trim panel and the passenger. In order to
help provide this additional protection, the side
airbag must inflate within a fraction of a second
at very high speed and with great force . The sup­
plemental side airbag could injure you if your
seating position is not proper or upright or if
items are locat ed in the area where the supple­
mental side airbag expands. This applies espe­
cially to children
c;, page 277, Child safety. Sup­
plemental side airbags inf late between the occu­
pant and the door panel on the side of the vehicle
that is struck in certain side collision ¢
fig. 226 .
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 upper part
of the body.
A fine dust may develop when the airbag deploys.
This is normal and does not mean there is a fire
in the vehicle .
Airbag system
Important safety instructions on the side
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 and your passengers must
know and act accordingly to help the safety belts
and airbags do their job to provide supplemental
protection.
A WARNING
An inflating side airbag can cause serious or
fatal injury. Improperly wearing safety belts
and improper seating positions increase the
risk of serious personal injury and death
whenever a vehicle is being used.
- In order to reduce the risk of injury when
the supplemental side airbag inflates:
- Always sit in an upright position and never
lean against the area where the supple­
mental side airbag is located.
- Never let a child or anyone else rest their
head against the side trim panel in the
area where the supplemental side airbag inflates.
- Always make sure that safety belts are
worn correctly,
- Do not let anyone sitting in the front seat
put their hand or any other parts of their
body out of the window.
- 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 de­ ploy.
- 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.
