ance with United States Fe dera l Moto r Vehicle Safety Sta ndard
(FMVSS) 2 08 as a pplicable at t he time your vehi cle was manufac­
t u red . The safety belts for the seats have "pretensione rs" that help to
take slac k out of the belt sys tem. Th e prete nsion ers are a lso activ ate d
by the e lectron ic cont rol un it for the airbag system.
Th e front sa fe ty bel ts also have lo ad limi ters to help red uce th e forces
applied to the body in a crash.
Th e airbag for the driver is in t he steering whee l hub ~ fig. 1 81 and
t h e airbag for th e front pass enger is i n the inst rum ent pa nel
~ fig. 182 . The general locat ion of the airbags is marked "AIRBAG".
Th ere is a lo t you nee d to know abo ut the air bags in your vehicle. We
urge yo u to read the detai led information about airbags, safety be lts
and c hild s afety in this and the other chap ters that make up the
own er's literature. Please be sure to heed the WAR NIN GS· they are
extremely importan t for your safety an d the sa fe ty of your p asse n­

t he sec tio ns tha t foll ow and be su re to heed all of the WAR NIN GS.
& 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 197.
& 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 back
seat.

& WARNING
Damage to the front passenger seat can prevent the front airbag
from working properly.
• Imprope r repair or disassembly of the front passenger and
driver seat will prevent the Advan ced Airbag System from func­
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 Audi dealer. •
How the Advanced Airbag System
components work together
Th e fron t Advanced A irbag System and t he side airbags sup plemen t
the protect ion offered by the front three-po int safety belts with
prete nsioners and load limiters a nd t he adjusta ble head restra ints to
help reduce the risk of i njur y in a w ide range of acc ident and crash
situ ati ons. Be sure to re ad the important info rmat io n a bou t safe ty
and heed the WAR NINGS in this chapte r.
Deployment of the Adv a need Airbag System and the a ct iva tion of t he
sa fety belt pretens ioners depend on the dece leration measured by
the c rash sensors and reg istered by the e lectron ic contro l un it. Crash
sever ity depe nds on speed and deceleration as well as the mass and
st iffness of t he ve hicle or object invo lved in the crash.
Whe n the ele ct ronic con tro l u nit r egi sters a low sever ity crash and
the safety be lt is being used, the airbag will not dep loy . If the safety
bel t is not being used, the fi rs t st age de ploys, followed by the second

eration is high enough to dep loy the a irbags .
Front airbags will not deploy:
• if the ignition is switched off when a crash occurs,
• in s ide collisions ,
• in rea r-end collisions,
• in rollovers,
• when the crash decelerat io n me asured by the a irbag system is less

tered by the e lectron ic con trol un it.
The front passenger airbag also will not deploy:
• when the fron t passe nger seat i s not 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 =>

• A tight tether o r other strap on a rearward -facing child
restraint attached to the front pa ssenger 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 heavier weight regi stered
can make the system work as though an adult were on the seat
and deploy the Advan ced Airbag when it mu st be suppre ssed
causing serious or even fatal injury to the child .
• If , in exceptional circumstanc es, you must install a forward­
facing child restraint on the front passenger seat, always move
the seat into its rearmost 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

Repair, care and disposal of the airbags
Parts of the airbag system are
insta lled at many different places on
your Audi . Ins tall ing, remov ing, serv icing o r rep airi ng a pa rt in an
area of the vehicle ca n damage a part of a n airbag system and prevent
t ha t sys tem from working prope rly in a coll is io n.
Th ere are some importa nt things you have to know to ma ke sure t hat
the effectiveness of the system will not be impai red and that
dis ca rded compo nents do not cause injury or po llute t he e nvir on­
ment .
& WARNING
Improper care , serv icing 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 units .
• 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 has the training and special equip­ ment necessary .
• For any work on the airbag system, we strongly recommend
that you see your authorized Audi dealer or qualified workshop.
• Never modify the front bumper or parts of the vehicle body . ..,_

Other things that can affect Advanced
Airbag performance
Chang ing the vehicle's suspension system can change the way that
t h e Advan ced Airbag System pe rforms in a cr ash . For e xamp le, usi ng
tire-rim combinations not app roved by Audi, lowering the vehicle,
c hang ing the stiffness o f th e suspension, incl uding the sp rings,
suspension struts, shock absorbers etc. can change the forces that
are meas ured by the a irbag sensors and sent to the ele ct ronic contro l
unit . Some suspension changes can, fo r exam ple, increase the force
levels measured by the senso rs and make the airbag system deploy in
crashes in which i t would not deploy if the changes had no t been
ma de . Other kinds of changes may reduce the force levels meas ured
by the sensors and p revent the airbag from dep loying when it should.
T he sensors in the safety belt b uckle for the drive r and front
p as senge r se at tell the e lectroni c cont rol mo dule if the sa fe ty belt is
latched or not . If the safety belt is being used, t he front a irbag w ill

safety belt is not be ing used . Therefo re, in a par ticular collis io n, it is
possible that an a irba g w ill not dep loy at a seating position where the
safety belt is being used but w ill inflate at the posit ion where the
safety belt is not be ing use d. It is im portant that nothing interfere
w it h t he safety belt bu ckles so that t he sensors can se nd the co rrect

& WARNING
Changing the vehicle's susp ension including use of unapproved
tire -rim combination s can change Advan ced Airbag performance
and increase the risk of serious personal injury in a crash .
• Never install suspension component s that do not have the
same performance characteristics as the components originally
installed on your vehicle.
• Ne ver use tire-rim combinations that have not been approved
by Audi.
& WARNING
Items stored between the safety belt buckle and the center
console can cause the sensors in the buckle to send the wrong
