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 autho­
rized Audi dealer.
& WARNING
If the front airbag inflates, a child without a child restraint, 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 safety seats on the
rear seat -even with an Advanced Airbag System.
• If you must install a rearward-facing child safety seat on the
front passenger seat because of e xceptional circumstances and
the PASSENGER AIR BAG OFF light does not appear and stay on, immediately install the rear-facing child safety seat in a rear ..,

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.

are wearing your safety belt and wear ing it properly . This is why you
should always wear your safety belt, not just because the law requires
you to do so=>
page 181, "General notes".
The safety belt buckle for the driver and front seat passenger have
switches that tell the airbag control module if the safety belt is being
used or not. If the safety belt is being used, the knee airbag will
dep loy at a slightly higher rate of deceleration than if the belt is not
being used. Therefore, in a particular collision, it is poss ible that an
airbag will not deploy at a seating position where the safety belt is
being used but will inflate at the position whe re the safety be lt is not
being used.
Remember too, airbags w ill deploy only once and only in certa in kinds
of accidents -your safety belts are always there to offer protection in
t hose accidents in which airbags are not supposed to deploy or when
they have already deployed, for example when your vehicle strikes or
is struck by another after the first collision.
This is just one of the reasons why an airbag is not a substitute for the
safety belt. The airbag system wo rks most effective ly when used with
the safety belts. Therefore, always wear your safety belts correctly .
It is important to remember that while the supplemental airbag
system is desig ned to reduce the likelihood of serious injuries, other
injuries, for example, swe lling, bruis ing, and minor abrasions can
also be associated with airbags.
The knee airbag system basically consists of:
• Th e electronic control module
• T wo inflatable airbags (airbag and gas generator), 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 collis ions when the decelerat ion measured by the
control unit is too low
• in s ide collisions
Safety first Vehicle OP-eration
Airbag system
• in rear-end collisions
• in rollovers
• in the event of a system ma lfunction (warning/indicator light illu­
minated)=>
page 16 .
& WARNING
• Safety belts and the airbag system can only provide protection
when occupants are in the proper seating position =>
page 199.
• 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.

Side airbags
Description of side airbags
The airbag system can provide supplemental protection
to properly restrained occupants.
Fig. 183 Side airbag
location in the driver's
seat
The side airbags are located in the sides of the front seat backrests
=>
page 209, fig. 183. They are identified by the word "AIRBAG" .
The side airbag system basically consists of:
• the electronic control module and external side impact sensors
• the two side airbags located in the sides of the front backrests
• the airbag warning light in the instrument cluster.
The airbag system is monitored electronically to make certain that it
is functioning properly at all times. Each time you turn on the igni­
tion, the airbag system indicator light will 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 and front passenger's upper
torso on the side of the vehicle that is struck in a side collision. The
airbag deploys only in side impacts and only when the vehicle acceler­
ation registered by the control 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 badly
Safety first Vehicle OP-eration
Airbag system
damaged as a result of the collision. It is not possible 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 210, "Important safety instructions on the side
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
collision 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 vehicle. Always
remember that the side airbag system can only help to protect you if
you are wearing your 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 181, "General notes".
It is important to remember that while the supplemental 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 deploy 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 airbag activa­
tion. In some collisions, both front and side airbags may inflate.
Remember too, that airbags will deploy only once and only in certain
kinds of collisions -your safety belts are always there to offer protec­
tion in those accidents in which airbags are not supposed to deploy or
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
too low
• in front-end collisions

& WARNING (continued)
-Never let a child or anyone else rest their head against the
side trim panel in the area where the supplemental side airbag
inflates.
- Always make sure that safety belts are worn correctly,
- Do not let anyone sitting in the front seat put their hand or
any other parts of their body out of the window.
• Always make sure that the side airbag can inflate without
interference.
- Never install seat covers or replacement upholstery over the front seat backs that have not been specifically approved by
Audi.
- Never use additional seat cushions that cover the areas
where the side airbags deploy.
- Damage to the original seat covers or to the seam in the area
of the side airbag module must always be repaired immedi­
ately by an authorized Audi dealer.
• Objects between you and the airbag can increase the risk of
injury in an accident by interfering with the way the airbag unfolds
or by being pushed into you as the airbag inflates. -Never place or attach accessories or other objects (such as
cupholders, telephone brackets, or even large, bulky objects)
on the doors, over or near the area marked "AIRBAG" on the
seat backrests.
- Such objects and accessories can become dangerous projec­
tiles and cause injury when the supplemental side airbag deploys.
- Never carry any objects or pets in the deployment space
between them and the airbags or allow children or other
passengers to travel in this position.
• Always use the built-in coat hooks only for lightweight
clothing. Never leave any heavy or sharp-edged objects in the

cause personal injury in an accident.
• Always prevent the side airbags from being damaged by heavy
objects knocking against or hitting the sides of the seatbacks.
• The airbag system can only be triggered once. If the airbag has
been triggered, the system must be replaced by an authorized
Audi dealership.
• Damage (cracks, deep scratches etc.) to the original seat covers
or to the seam in the area of the side airbag module must always
be repaired immediately by an authorized Audi dealer.
• If children are seated improperly, their risk of injury increases
in the case of an accident=>
page 215, "Child Safety".
• Never attempt to modify any components of the airbag system
in any way.
• In a side collision, side airbags will not function properly if
sensors cannot correctly measure increasing air pressure inside
the doors when air escapes through larger, unclosed openings in
the door panel.
- Never drive with interior door trim panels removed.
-Never drive when parts have been removed from the inside
door panel and the openings they leave have not been properly
closed.
- Never drive when loudspeakers in the doors have been removed unless the speaker holes have been properly closed.
- Always make certain that openings are covered or filled if
additional speakers or other equipment is installed in the
inside door panels.
- Always have work on the doors done by an authorized Audi
dealer or qualified workshop. •
