Your vehicle is equ ipped with an "Advanced A irbag System" in compli­
ance with United States Federal Moto r Veh icle Safety Standard
(FMVSS) 208 as applicable at the time you r veh icle was ma nufac­
t u red . The system senses the position of the fro nt seats and controls
front a irbag inflation w ith a valve, depending on the d istanc e
between the respective seat and the steer ing wheel or instrument
pa ne l. The safety be lts fo r the seats have "pretens ioners" that help to
take slack o ut of the belt system. The pretensioners are also activated
by the e lec tron ic control u nit for the airbag system.
The front safety be lts also have load limiters to help red uce the forces
applied to the body in a crash .
T he a irbag for the driver is in the steering whee l hub~ fig. 177 and
the airbag for the front passenger is in the instrument panel
~ fig. 178. The gene ral loca tion of the air bags is mar ked "AIRBAG".
T here is a lot you need to know about the a irbags in your vehicle . We
urge you to read the detai led information about airbags, safety be lts
and child safety in this and the other chapters that make up the
owner's literature. Please be sure to heed the WARNINGS -they are
extreme ly important fo r your safety and the safety of your passe n­
gers, especially infants and small children.
& WARNING
Never rely on airba gs alone fo r protection.

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 activation of the
safety belt pretensioners depend on the deceleration measured by
the crash sensors and registered by the electron ic control unit. T he
amount of inflation of the front airbags can a lso be adapted to the
front seat position, depending on the distance between the respec­
tive front seat and the steering wheel or instrument panel as regis­
tered by sensors in the seats. Crash severity depends on speed and
deceleration as well as the mass and stiffness of the vehicle or object
involved in the crash .
On the passenger side, regardless of safety belt use, the air bag w ill
be turned off if the weight on the passenger seat is less than the
amount programm ed in the electronic control unit . The front airbag
on the passenger side will also be turned off if one of the chi ld safety
seats that has been certified under Federal Motor Vehicle Safety
Standard 208 has been recognized on the seat. The

=> page 192, "Child rest raints on the front seat -some important
things to know".
& WARNING
To reduce the risk of injury when an airbag inflates, always wear
safety belts properly.
• If you are unrestrained, leaning forward, sitting sideways or
out of position in any way, your risk of injury is much higher .
• You will also 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=>

More important things to know about front
airbags
Fig. 17 9 Inflated
front airbags
Safety belts are important to help keep front seat occupants in the
proper seated position so that airbags can unfold properly and
prov ide supplemental protection in a frontal collision.
Th e front airbags are designed to provide additiona l protection for
the chest and face of the driver and the front seat passenger when:
• safety belts are worn properly,
• the seats have been positioned so that the occupant is properly
seated as far as possible from the airbag ,
• and the head restraints have been properly adjusted .
Because airbags inflate in the blink of an eye with great force, things
you have on your lap o r have placed on the seat could become
dangerous projectiles, and be pushed into you if the airbag inflates.
When an airbag deploys, fine dust is released. This is normal and is
not caused by a fire in the vehicle. This 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 supplemental airbag
system is desig ned to reduce the likelihood of serious injur ies, other
injuries, for example swell ing, bruising and m inor abrasions, can also
happen when airbags inflate. Airbags do not protect the arms or the •

lower parts of the body. Front airbags only supplement the three
point s afety be lts i n some fro ntal c ollisions in which t he vehicle de ce l­
eratio n is h igh enough to dep loy the a irbags.
Front airbags will not deploy:
• if the ignition is sw itched off when a cras h occu rs,
• in s ide collisions,
• in rea r-end collisions,
• in rollovers,
• when the cras h deceleration me asured by the ai rbag syste m is less
than t he m in imum threshold needed for airbag dep loyment as regis­
t ere d by the e lectro nic cont rol unit.
The front passenger airbag will also not deploy:
• when the fron t pa sse nger sea t is not o ccupied,
• when the we ight on the front passenge r seat as sense d by the
Advanced Airbag Sys tem in dicates t hat the front airbag on the
passenger side has to be turned off by t he e lectron ic control un it (the
PASSENGER AIR BAG OFF light comes on and st ay s on).
& WARNING
Sitt ing in the wrong posit ion can increa se the risk of serious injury
in crashes .
• To reduce the risk of injury when the airbags inflate , the driver
and passengers must always sit in an upright position , must not
lean against or place any part of their body too close to the ar ea
where the airbags are located.
• Occupants who are unbelted, out of position or too close to the
airbag can be ser iously injured by an airbag as it unfolds with
great force in the blink of an eye=>
page 192.
& WARNING
A child in a rearward-facing ch ild safety seat installed on the front
pa ssenger seat will be seriou sly injured and can be killed if the
front airbag inflates -even with an Advanced Airbag System.
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest, center armrest , door or roof.
• Always install rear-f acing child safety seats on the rear seat.
• If you must install a rearward facing child safety seat on the
front p assenger seat because of e xceptional circumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on,
i mmediately install the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your
authorized Audi dealer.
& WARNING
Objects between you and the airb ag wilt increase the risk of injury
in a crash by interfering with the way the airbag unfolds or by
being pushed into you as the airbag inflates.
• N ever hold things in your hands or on your lap when the vehicle
is in use.
• Never tran sport items on or in the area of the front passenger
seat . Object s could move into the area of the front airbag s during
brak ing or other sudden maneuver and become dangerous projec­
tiles that can cause serious personal injury if the airbags inflate.
• Never place or attach accessories or other objects (such as
cupholders , telephone bra ckets , large, heavy o r bulky objects) on
the doors, over or near the area marked "AIRBAG " on the steering
wheel, instrument panel , seat backrests or between those areas
and yourself . The se obj ect s could cause injury in a crash , especially
when the airbags inflate .
• Never recl ine the front passenger's seat to transport objects.
Items can also move into the area of the side airbag or the front ..,

seating position and have the airbag system inspected by your
authorized Audi dealer .
• A tight tether or othe r strap on a rearward-facing child
restraint attached to the front passenger seat can put too much
pressure on the weight-sensing mat in the seat and register more
weight than i s actually on the seat. The heav ier weight registered
can make the system work as though an adult 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 ex ceptional circumstances, you must install a forward·
facing child restraint on the front passenger seat, always move
the seat into i ts rearmo st po sition in the seat's fore and aft adjust ·
ment 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 do es not go out when an
adult is sitting on the front passenger seat after taking the steps
de scribed above, make sure the adult i s properly seated and
restrained at one of the rear seating positions.
• Have the airbag system inspected by your authorized Audi
dealer before transporting anyone on the front passenger seat.
[ i ] Tips
If the we ight-sens ing mat in the front passenger seat detects an
empty seat, the front a irbag on the passenger side w ill be t urne d off,
and PASS ENGER AIR BAG OFF will stay on.•
Repair, care and disposal of the airbags
Parts of the a irbag system a re installed at many different p laces on
your Audi. Inst all in g, 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 preve nt
t ha t system from working pro perl y in a coll is ion.
T here are some important thi ngs you have to know to make sure that
the effectiveness of the system will not be impa ired an d that
discarded components do no t cause injury or poll ute the enviro n­
ment .
& WARNING
Improper care , servicing and repair procedures can increase the
risk of personal injury 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 cupholders or telephone
mountings to the surfaces covering the airbag unit s.
• For cleaning the horn pad or instrument panel, use only a soft,
dry cloth or one moistened with plain water. Solvent s or cleaners
could damage the airbag cover or change the stiffness or strength
of the material so that the airbag cannot deploy and protect prop·
erly .
• Never repair, adjust, or change any part s of the airbag system .
• All work on the steering wheel, instrument panel , front seats
or electrical sy stem (including the installation of audio equip·
ment , cellular telephones and CB radios, etc .) must be performed
by a qualified technician who ha s the training and special equip ·
ment necessary .
• For any work on the airbag system, we strongly re commend
that you see your autho rized Audi dealer or qualified workshop.
• Never modify the front bumper or parts of the vehicle body.

If the front airbags deploy, the knee airbags also deploy in frontal
collisions above a certain severity.
When the system is deployed, the a irbags start to fill with a propel­
lant 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 199, fig. 179.
Altho ugh 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
extremities.
All this takes place instantaneously, so fast that many people don't
even realize that the airbags have deployed. The airbags also inflate
w ith a great deal of force and it is important fo r occupant safety that
nothing should be in their way when they deploy.
Fully inflated airbags in combination with properly worn safety belts
slow down and limit the occupant's forward movement and help to
red uce the risk.•

Important safety instructions on the knee
airbag system
Airbags are only supplemental restraints. Always wear
safety belts correctly and ride in a proper seating posi­
tion.
Th ere is a lot that yo u and your passengers must know and do to help
the safety belts and a irbags to prov ide supp lemental protection.
& WARNING
An inflating knee airbag can cause serious injury. Wearing safety
belts incorrectly and improper seating positions increase the risk
of serious personal injury and death whenever a vehicle is being
used.
& WARNING (continued)
• The airbag system cannot protect you properly if you are seated
too close to any of the airbag locations. When adjusting their seat
positions, it is important that both the driver and the front
passenger keep their upper bodies and knees at the following
minimum safe distances:
- 10 inches (25 cm) between the chest and the steering
wheel/instrument panel.
- 4 inches (10 cm) between the knees and the lower part of
the instrument 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 increases even more should the
airbag deploy.
• Always make sure that the knee airbag can inflate without
interference. Objects between yourself and the airbag can increase
the risk of injury in an accident by interfering with the way the
airbag deploys or by being pushed into you as the airbag deploys .
- No persons (children) or animals should ride in the footwell
in front of the passenger seat. If the airbag deploys, this can
result in serious or fatal injuries.
- No objects of any kind should be carried in the footwell area
in front of the driver's or passenger's seat. Bulky objects (shop­
ping bags, for example) can hamper or prevent proper deploy­
ment of the airbag. Small objects can be thrown through the
vehicle if the airbag deploys and injure you or your passengers.
• Make sure there are no cracks, deep scratches or other damage
in the area of the instrument panel where the knee airbags are
located.
• If children are incorrectly seated, their risk of injury increases
in the case of an accident =>

How the system works
The Anti-Lock Brake System (ABS), Elect ronic D ifferential Lock (EDL)
and the Anti-Slip Regul ation System (AS R) are in teg rated in the e lec ­

th ese fun ctions, the ESP control unit re quires addi tional meas ure ­
ment data provided by hig h pe rformance senso rs . The ro tat ional
speed of the vehicle about its vertical axis, veh icle acceleration in the

Servotronic® - advanced power
steering system
The power steering systems uses the power of the
running engine to allow precise steering with little effort .
The advanced Servotronic® power steering system senses the road
speed and ele ct ronically adjusts power assistance to provide
comfortable and safe steering response exactly matched to the
veh icle speed .
Power steering will not work if the engine is off . As a resu lt, the
steeri ng wheel will be hard to turn.
T he power steeri ng fluid level is checked du ring the sched uled main ­
tenance services .
0 Note
If there is an electronic malfunction, servotronic will still function
like a conventional power s teer ing system, provid ing a cons tant
steering support force that is no longer proportionate to the vehicle
speed. This is most noticeable when t urning the s teer ing wheel at low
speeds (for example when park ing) , - more effor t will be required
than us ua l.
• Be aware of the d ifferent than usual steering response and adjust
your stee ring force accord ingly .
• Have the prob lem checked and set r ight by an Audi dealer as soon
as possib le.
[ i ] Tips
• When the e ngine is running, neve r hold the stee ring whee l turned
all the way to the rig ht or to the left for longer than 15 seconds. The
powe r steering pump wi ll overheat the hydra ulic fluid if yo u keep
holding the steering wheel turned all the way . This is likely to damage
t he power s teer ing system . •
If the power steering system s hou ld fa il entirely, or if the engine
is no t ru nning (fo r examp le, while be ing towed), you will st ill be able
to steer the vehicle. However,
considerably more effort will be
req uired to do so .
• If the power steering system should have a leak, or is not func­
tioning prope rly, con tact your au thor ized A udi dealer immedia tely.
• The power steer ing system requires a specia lly formulated
hyd raulic fluid. The power steer ing rese rvoir is the one loc ated
