or the low er parts of the body . Front airbags only supplement th e
th re e po int safe ty b elts in som e front al c ollis ions in which the
vehic le dece lerat ion is h igh enou gh to deploy the a irba gs.
Front airbags will not deploy:
• if the ignition is switched off when a crash occurs,
• i n sid e coll is io ns,
• in r ear- e nd collisi ons ,
• in ro llovers,
• when th e cras h de cele ration meas ured b y th e a irba g sys tem is

& WARNING
Sitting in the wrong position can increase 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 area
where the airbags are located.
• Oc cupants who are unbelted , out of position or too close to the
airbag can be seriously injured by an airbag as it unfolds with
great force in the blink of an eye
=> page 220.
& WARNING
A child in a rearward -facing child seat installed on the front
passenger seat will be seriously injured and can be killed if the
front airbag 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 arm rest , 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
PASSENGER AIR BAG OFF light does not come on and stay on ,
immediately install the rear-facing child seat in a rear seating posi­
tion and have the airbag system inspected by your Audi dealer.
& WARNING
Objects between you and the a irbag will 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.
• 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 during
braking 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 cup
holders, telephone brackets, large , heavy or 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 . These objects could cause injury in a crash, espe­
cially 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
airbag during braking or in a sudden maneuver. Objects near the .,_

& WARNING (continued )
airbags can become projectiles and cause injury , part icularly when
the seat is reclined .
& WARNING
The fine dust created when airbags deploy can cause breathing
problems for people with a history of asthma or other breathing
conditions.
• To reduce the risk 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 doors.
• 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
scratches .
• If the residue should get into your eyes , flush them with
water. •

Important safety instructions on monitoring
the Advanced Airbag System
& WARNING
An airbag system that is not functioning properly cannot provide
supplemental protection in a frontal crash.
• If the airbag indicator light comes on , it means that there may
be something wrong with the Advanced Airbag System . It is
possible that the airbag will inflate when it is not supposed to , or
will not inflate when it should.
• Have the airbag system inspected immediately by your Audi
dealer.
& WARNING
If the front airbag inflates , a child without a child restraint , in a
rearward-facing child seat or in a forward-facing child restraint
that has not been properly installed will be seriously injured and can be killed.
• Even though your vehicle is equipped with an Advanced Airbag
System , make certain that all children , especially 12 years and
younger, always ride on the back seat properly restrained for their
age and size .
• Always install forward or rear -facing child seats on the rear
seat -even with an Advanced Airbag System .
• If you must install a rearward-facing child seat on the front
passenger seat because of exceptional circumstances and the
PASSENGER AIR BAG OFF light does not appear and stay on , imme ­
diately install the rear-facing child seat in a rear seating position
and have the airbag system inspected by your Audi dealer .

&, W ARNING (continued )
• A tight tether or other strap on a rearward-facing child restraint
attached to the front passenger seat can put too much pres sure
on the weight-sensing mat in the seat and reg ister more weight
than is actually on the seat. The heavier 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 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 adjust­
ment range , as far away from the a irbag 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 tak ing the steps
described 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 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
e mp ty s eat, th e front air bag o n the pass enge r sid e wil l be tur ned
off, and PASSENGER AIR BAG OFF will stay on.•
Repair, care and disposal of the airbags
Parts of the airbag system are insta lled at many different places o n
yo ur Au di. In stal li n g, r emo vin g, s ervic ing or rep airi ng a part i n an area of the vehicle can damage a part of an airbag system and
p re vent that sys tem from wor king pr operly in a c ollis ion.
Th ere are some important th ings you hav e to know to ma ke sure
that t he effectivenes s of the system will not be impai red and that
discar ded co mponents do not ca use injury o r po llut e 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 atta ch any objects su ch as cup holders 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. 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 prop­
erly .
• Never repair , adjust, or change any parts of the airbag system .
• All work on the steering wheel, instrument panel , front seats or
electrical system (including the installation of audio equipment ,
cellular telephones and CB radios , etc .I 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 authorized Audi dealer or qualified workshop .
• Never modify the front bumper or parts of the vehicle body .
