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, or in
a rearward-facing child safety 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 i s 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,
immediately install the rear-facing child seat in a rear seating

position and have the airbag system inspected by your Audi
deal er.
• 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 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 the PASSENGER
AIR BAG OFF light w ill stay on .•
Repair, care and disposal of the airbags
Parts o f the a irbag system are installed at many different p laces on
your Audi. Install ing, 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 and 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 cup holders 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 o r qualified workshop.
• Never modify the front bumper or parts of the vehicle body.

a ir ba g
The a irbag for the dr iver is located in the inst rument pane l under­
neath the steering wheel~ fig . 216, t he airbag for the passenger is
at abo ut the same height in t he instr ument panel underneath the
glove compartment.
Th e knee airbag offers addit ional protec tion to the dr ive r's and
passenger's knees and upper and lower thigh areas as a s upplement
t o the sa fety bel ts.
If the front a irbags dep loy, the knee airbags a lso deploy i n frontal
co llisions above a certain severity~
page 215, "More importan t
t hings to know abou t front airbags ".
Besides the ir no rma l safety function , safety belts work to help keep
t he drive r o r front passenger in po sit ion in c ase of a frontal collision
so that the a irbags can provide protection .
Th e airbag system is not a substitute for your safety belt . Rather, it is
pa rt of the ove rall occ upant re st ra int system in your veh icle. Always
remember t hat the airbag system can on ly help to protect you if you
are wearing your safety be lt and wear ing it pr operly . T his is why you ..

should always wear your safety belt, not just because the law requires
you to do so=>
page 197 , "General notes".
The safety belt buckle for the driver and front seat passenger have
switches that tell the airbag control module if the safety be lt is being
used or not.
If the safety belt is being used, the knee airbag will
dep loy at a s lightly higher rate of deceleration than if the be lt is not
being used. Therefore, in a particular collision, it is possible that an
airbag will not deploy at a seating position where the safety be lt is
being used but will inflate at the position where the safety belt is not
being used.
Remember too, airbags will deploy only once and only in certain kinds
of accidents -your safety belts are always there to offer protection in
those accidents in which airbags are not supposed to deploy or when
t hey have already deployed, for example when you r vehicle strikes or
is struck by another after the first collision.
Thi s is just one of the reasons why an airbag is not a substitute for the
safety belt . The airbag system works most effectively when used with
the safety belts. Therefore, always wear your safety belts correctly.
It is im portant to remembe r th at while the supplemental airbag
system is designed to reduce the likelihood of serious injur ies, other
injuries, for example, swe lling, bruis ing, and minor abrasions can
also be assoc iated with airbags.
The knee airbag system basically consists of:
• The electronic contro l module
• Two inflatable airbags (airbag and gas gene rator), one for the
driver and one for the front passenger
• The airbag indicator light in the instrument panel
The knee airbag system will not deploy:
• when the ignition is turned off
• in front-end collisions when the deceleration measured by the
control unit is too low
• in s ide collisions
• in rear-end collisions
Safety first Vehicle OP-eration
Airbag system
• in rollovers
• in the even t of a system ma lfunction (warning/ indicator lig ht ill u­

page 17.
& WARNING
• Safety belts and the airbag system can only provide protection
when occupants are in the proper seating position =>
page 215.
• If the airbag indicator light comes when the vehicle is being
used, have the system inspected immediately by your authorized
Audi dealer. The airbag may not work properly when the vehicle
acceleration in a side collision is high enough to deploy the airbag.

How knee airbags work
The risk of injury to the leg area is reduced by fully

Fig. 217 Inflated
airbags protecting in a
frontal collision
The knee airbag system has been designed so that the airbags for the
dr iver and front passenger are dep loyed in certa in but not all frontal
collisions.
If the front airbags deploy, the knee airbags also deploy in frontal
collisions above a certain sever ity.

& WARNING
An inflating knee airbag can cause serious injury. Wearing safety
belts incorrectly and improper seating positions increase the risk
of seriou s personal injury and death whenever a vehicle is being
used.
• 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
& WARNING (co ntinued )
passenger keep their upper bodies and knees at the following
minimum safe di stances:
- 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 k ind 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 deploy s 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 =>
page 231, "Child Safety". •

Side airbags
Description of side airbags
The airbag system can provide supplemental protection
to properly restrained occupants .
Fig. 218 Side airbag
locat ion in the driver's
seat
The side airbags are located in the sides of the front seat backrests
=> fig. 218 and the rear backrest facing the doors. They are identified
by the word "AIRBAG" .
The side airbag system basically consists of:
• the electronic control module and external s ide impact sensors
• the two side airbags located in the sides of the front backrests
• two rear side airbags
• the airbag warning light in the instrument cluster.
Th e airbag system is mo nitored electronically to make certain that it
is funct ion ing properly at all times. Each time you turn on the igni­
tion, the airbag system indicator light wi ll come on for a few seconds
(self diagnostics).
The side airbag system supplements the safety belts 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 collision.
The air bag deploys on ly in s ide impacts and only when the vehicle
acceleration registered by the contro l unit is high enough. If this rate
Safety first Vehicle OP-eration
Airbag system
is below the reference value programmed into the control unit, the
side airbags will no t be triggered, even though the car may be badly
damaged as a result of the collision . It is not poss ible to define an
airbag triggering range that wi ll cover every possib le angle of impact,
since the circumstances will vary considerably between one collision
and another . Important factors include, for example, the nature
(hard or soft) of the impacting object, the angle of impact, vehicle
speed, etc.=>
page 226, "Important safety instructions on the s ide
airbag system".
Aside from their normal safety function, safety belts work to help keep the driver or front passenger in position in the event of a side
co llision so that the side airbags can provide protection .
The airbag system is
not a substitute for your safety belt. Rather, it is
part of the overall occupant restraint system in your veh icle. Always
remember that the side airbag system can only help to protect you if
you are wearing yo ur safety belt and wearing it properly. This is
another reason why you should always wear your safety belts, not just
because the law requires you to do so=>
page 197, "Genera l notes".
It is important to remember that while the supp lemental side airbag
system is designed to reduce the likelihood of serious injuries, other
injuries, for example, swelling, bruising, and minor abrasions can
also be associated with deployed side airbags. Remember too, side
airbags will dep loy only once and only in certain 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 indication of over-sensitive or failed a irbag activa­
tion. In some collisions, both front and side airbags may inflate .
Remember too, that airbags will deploy only once and on ly in certain
kinds of collisions -your safety belts are always there to offer protec­
tion in those accidents in wh ich airbags are not supposed to deploy o r
when they have already deployed.
The side airbag system will not deploy:
• when the ignition is turned off
• in side collisions when the acceleration measured by the sensor is
toolow

s ide curtain airbag
location
The side curtain airbags are located on both sides of the interior
above the front and rear side windows=> fig. 220. They are identified
by the word "AIRBAG" on the windshield frame and the center roof
pillar.
The side curta in airbag system s upplements the safety belts and can
help to reduce the risk of injury for occupants' heads and upper torso
on the side of the vehicle that is struck in a sid e collision . The s ide
curtain a irbag inflates only in side impacts and only when the vehicle
acceleration registered by the contro l unit is high enough . If this rate
is below the reference value programmed into the control unit, the
side airbags will not be triggered, even though the car may be bad ly
damaged as a result of the collision.
It is not possib le to define an
airbag triggering range that will cover every possible angle of impact,
since the circumstances will vary considerably between one collision
and another. Important factors include, for example, the nature
(hard or soft) of the impacting object, the angle of impact, vehicle
speed, etc.=>
page 229, "How side curtain airbags work" . Aside from their normal safety function, safety belts work to help

It is important to remember that while the side curta in airbag system
is designed to he lp reduce the like lihood of serious injuries, other
injuries , for example, swell ing, bruis ing, and minor abrasions can
also be assoc iated with these airbags upon deployment. Remember
t oo, these airbags wi ll dep loy only once and only in certain kinds of
accidents - your safety belts are always there to offer protection .
The side curtain airbag system basically consists of:
• The electronic control module and external side impact sensors
• The side curtain airbags above the front and rear s ide windows
• Th e airbag indicator light in the instrument panel
The airbag system is mon itored electron ically to make certain it is
functioning properly at all times . Each time you turn on the ignition,
the air bag system indicator light will come on for a few seconds (self
diagnostics).
The side curtain airbag is not activated:
• if the ignition is turned off,
• in side co llisions when the acceleration measured by the sensor is
too low,
• in front-end collisions,
• in rea r-end co llisions,
• in rollovers .
