& WARNING
To reduce the risk of injury when an airbag inflates, always wear
safety belts p roperly .
• If you are unrestrained, leaning forward, sitting sideways or
out of position in any way , your ri sk of injury is much higher.
• You will also receive serious injuries and could even be killed if
you are up again st the airbag or too close to it when it inflates -
even with an Advanced Airbag
=> page 209.
& WARNING
A child in a rearward-facing child safety seat installed on the front
pas senger seat will be seriously injured and can be killed if the
front airbag inflates -even with an Advanced Airbag System.
• Although the Advanced Airbag System in your vehicle is
designed to turn off the front airbag when a rearward-facing child
restraint has been installed on the front passenger seat, nobody
can absolutely guarantee that deployment is impossible in all
c onceivable situations that may happen during the useful life of
your vehicle .
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
c hild against the backre st, center armre st, door , or roof .
• Always install rearward-facing child restraints on the rear seat.

Advanced Airbag System components
T he front passenger seat in your veh icle has a lot of very important
parts o f the Advanced A irba g System in it. These parts incl ude t he
we igh t-sens ing ma t, sensors, wiring, brackets, and more. The func­
t ion o f th e sys tem in the fron t passenger sea t is chec ked by the elec ­
tron ic control unit w hen the ignit ion is on . The contro l u ni t mo nitors
the Advanced Airbag System and tu rns the airbag indicator light on
w hen a malfunct ion in t he system components is de tected. The func­
tion of the a irbag indicator light is descr ibed in greater detail below.
Be cau se the fr ont p assenge r se at con tain s im po rt an t p arts of th e
Advanced Airbag System, you m ust take care to prevent it from being damaged. Damage to the seat may prevent the Advanced A
irbag for
t he fro nt passenge r se at from do ing its job in a cr ash.
The front Advanced Airbag System consists of the
following:
• Cras h sensors in the front of t he veh icle that measure vehicle
a cc ele ra tion/de ce le ra tion to prov ide i nform ation to the Adv ance d
Airbag System about the severity of the crash .
• An e lec tron ic contro l uni t, w it h in tegr ate d cr ash sensor s fo r fron t
and side impacts. T he control unit "dec ides" w het her to fire the front
a irbags based on the info rm at ion rece ive d fr om t he c rash se nso rs.
The contro l unit also "decides" whether the safety be lt prete nsione rs

tioning properly.
• Repairs to the front passenger seat must be performed by qual­
ified and properly trained workshop personnel.
• Never remove the front passenger or driver seat from the
vehicle.
• Never remove the upholstery from the front passenger seat.
• Never disassemble or remove parts from the seat or disconnect
wires from it .
• Never carry sharp objects in your pockets or place them on the
seat. If the weight-sensing mat in the passenger seat is punctured
it cannot work properly .
• Never carry th ings on your lap or carry objects on the passenger
seat . Such items can increase the weight regi stered by the weight­
sensing mat and send the wrong information to the airbag control
unit.
• Never store items under the front passenger seat. Parts of the
Advanced Airbag System under the passenger seat could be damaged, preventing them and the airbag system from working
properly.
• Never place seat covers or replacement upholstery that have
not been specifically approved by Audi on the front seats .
• Seat covers can prevent the Advanced Airbag System from
recognizing child restraint s or occupants on the front passenger
seat and prevent the side airbag in the seat backrest from
deploying properly .
Controls and equip­ ment Safety first Vehicle operation
& WARNING
(co ntinued )
• Never use cushions , pillows, blankets or similar items on the
front passenger seat . The additional padding will prevent the
weight-sensing mat in the seat from accurately registering the
c hild restraint or person on the seat and prevent the Advanced
Airbag System from functioning prope rly.
• If you must use a child restraint on the front passenger seat
and the child restraint manufacturer's instructions require the use
of a towel, foam cushion or something else to properly pos ition
the child restraint, make certain that the PASSENGER AIR BAG
OFF light come s on and stays on whenever the child re straint is
installed on the front passenger seat.
• If the PASSENGER AIR BAG OFF light does not come on and
stay on, immediately install child restraint in a rear seating posi­
tion and have the airbag system inspe cted by your authorized Audi
dealer. •

belt is not being used, t he first stage dep loys, followed by the second
stage a fter a mu ch later time in the c rash seq uence .
If the electronic control un it reg isters a crash of medium severity, the
first stage of the airbag deploys fo llowed by the second stage at a
much la ter t ime in the crash sequence -regard less of whethe r th e
safety belt is being used or not. In higher sever ity crashes as regis­
t ere d by t he elect ronic con tro l u ni t, both the first and second stages
dep loy almost at the same time.
On the passenger side, regardless of safety be lt use, the a irbag will
be turned off if the we ight on the passenger seat is less than the
amount prog rammed in the electronic contro l unit. The front airbag
on the passenge r side w ill a lso be turned off if one of the ch ild safety
seats that has been certified under Federa l Moto r Vehicle Safety
Standar d 208 has bee n recognized o n th e seat. The
PASSENGER AIR

Advanced Airbag o n the passenger side has been tu rned off
~ page 211, "Ch ild restraints on the front seat -some important
t hings to know" .
& WARNING
To reduce the risk of injury when an airbag inflate s, always wear
safety belts properly .
• If you are unrestrained, leaning forward, sitting sidewa ys or
out of position in any way , you r risk of inju ry is mu ch 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. 2 00 Inflate d
front a irb ags
Safety belts are important to he lp keep front seat occupants in the
pro per seated pos ition so that a irbags can unfold prope rly and
prov ide supp lemental protect ion in a frontal collision.
Th e front airbags are designed to provide add itio na l protec tion for
the c hest and face of the driver and the front sea t passenge r when:
• safety belts are worn properly
• the seats have been posit ioned so that the occupant is prope rly
seated as far as possible from the airbag
• and the head restraints have been properly adjusted
Because air bags inflate in the b link of a n eye w it h great force, things
you have on your lap o r have place d on the seat cou ld become
dangerous projectiles, and be pushed into you if the a irbag inf lates.
When a n airbag dep loys, 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 l ubricate the ai rbags as they deploy.
It could irritate
skin .
It is important to remember that while the supp lemental airbag
system is desig ned to reduce the li ke lihood of serious injur ies, other
injuries, for example swelling, b ruising and m inor abras ions, can also
happen when airbags infl ate. Airbags do not p rotect the arms or the ..,_

lower parts of the body . Front a irbags s upplement the t hree-poi nt
sa fety belts o nly in some fro ntal collis ions in which the vehicle decel­
eration is high enough to dep loy the a irbags .
Front airbags will not deploy:
• if the ignition is switched off when a crash occ urs
• in s ide collis ions
• in rea r-end collisions
• in rollovers
• when the crash decelerat io n me asured by the a irbag system is less
than the min imum threshold needed for a irbag deployment as reg is­
tered by the e lectron ic con trol un it
The front passenger airbag also will not deploy:
• when t he fron t passenger sea t is no t oc cupied
• when the weight on the front passenger seat as sensed by the
Advanced Ai rbag System in dicates that the front airbag o n the
passenger side has to be turned off by the e lectronic control unit (the
PASSENGER AIR BAG OFF li ght comes on and stays on)
& WARNING
Sitting in the wrong position can increase the ri sk of ser iou s injury
in crashes.
• To redu ce the risk of injury when the airbags inflate, the driver
and pas sengers mu st always sit in an upright position , mu st not
lean against or place any part of th eir body too close to the area
where the airbags are lo cated.
• Occupants who are unbelted, out of position or too close to the
airbag can be seriou sly injured by an airbag a s it unfolds with
great force in th e blink of an eye =>
page 211 .
Controls and equip­
ment Safety first Vehicle operation
& WARNING
A child in a rearward-facing child
safety se at installed on the front
pas senger seat will be seriously injured and can be killed if the
front airbag inflates - ev en with an Ad vanced Airbag System.
• The inflating airbag will hit the child safety seat or infant
c arrier with great force and will smash the child safety s eat and
c hild against the backre st, center armre st, d oor or roof .
• Always install rear -facing child safet y seats on the rear seat.
• If you must install a rearward-facing child safety seat on the
front passenger se at because of e xceptional circumstances and
the PASSENGER AIR BAG OFF light do es not come on and stay on ,
immediately install the rear -facing child s afety seat in a rear
s eating po sition and h ave the airbag system inspe cted by your
authoriz ed Audi d ealer.
& WARNING
Object s between you and the airbag will increase the r isk of inju ry
in a cra sh by int erfering with the way the airb ag unfold s or by
being pushed into you as the airbag inflates.
• Never hold things in your hand s or on your lap when the vehicle
i s in use.
• Never tran sport items on o r in the are a of the fr ont pa ssenger
seat. Obje ct s c ould move into the area of the front ai rbag s during
braking or other sudden maneu ver s and become dang erous
projectiles that can c au se se rious per sonal injury if the ai rbags
infl ate.
• Never pla ce o r attach accessories or othe r objects (such a s
cupholders, telephone brac kets, large , heavy or bulky object s) on
the doo rs, over o r near the are a marked
"AIRBAG " on the stee ring

& WARNING (conti nued)
• Never recline the front passenger's seat to transport objects.
Items can also move into the area of the s ide airbag or the front
airbag 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 tilt the front pa ssenger seat backrest forward when the
vehicle is moving. An inflating ai rbag will force the backrest back ­
ward and can injure rear seat occupants.
& WARNING
The fine dust created when airbags deploy can cau se breathing
problem s for people with a history of a sthma or other breathing
condition s.
• To reduce the ri sk of breathing problems, those with asthma or
other respiratory conditions should get fresh air right away by
getting out of the vehicle or opening windows or door s.
• If you are in a collision in which airbags deploy , 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
scratche s.
• If the residue should get into your eyes, flush them with
water. •
