Advanced Airbag System components
The front passenger seat in your vehicle has a lot of very important
parts of the Advanced A irbag System in it. These parts inc lude the
weight -sensing mat, sensors, wiring, brackets, and more. The func -
Controls and equip­ ment Safety first Vehicle operation tion of the system in the front passenger seat is checked by
the elec­
tronic contro l unit when the ignition is on . The control unit monitors
the Advanced Airbag System and turns the a irbag indicator light on
when a malfunction in the system components is detected . The
function of the airbag indicator light is described in greater detail below. Because the front passenger seat conta ins important parts
of the Advanced Airbag System, you must take care to prevent it
from being damaged. Damage to the seat may prevent the
Advanced Airbag for the front passenger seat from doing its job in
a crash.
T he front Ad van ced Airbag System consi sts of th e
following:
• Crash sensors in the front of the vehicle that measure vehicle
acce leration/deceleration to provide information to the Advanced
A irbag System about the sever ity of the crash .
• An electronic control unit, with integrated crash sensors for front
and side impac ts. The control unit "decides" whether to fire the
front airbags based on the information received from the crash sensors . The control unit also "decides" whether the safety belt
pretensioners should be activated.
• An Advanced Airbag w ith gas generator and contro l valve for the
driver inside the steering wheel hub.
• An Advanced Airbag with gas generator and contro l valve inside
the instrument panel for the front passenger .
• A weight -sensing mat under the upholstery padding of the front
passenger seat cushion that measures the total weight on the seat .
The information registered is sent continuously to the e lectronic
control unit to regu late dep loyment of the front Advanced Airbag on
the passenger s ide.
• An airbag monito ring system and indicator light in the instru ­
ment cluster=> page
199.
• A sensor in each front sea t registers t he distance between the
respective seat and the steering wheel or instrument panel. The
information registered is sen t continuously to the electronic control
unit to regulate dep loyment of the front Advanced Airbags. ._

& 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.
• Occupants 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 190.
& WARNING
A child in a rearward-facing child safety 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 safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest, center armrest , door or roof.
• Always install rear-facing child safety seats on the rear seat.
• If you must install a rearward facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on, i mmediately install the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your
authorized Audi dealer .
& WARNING
Objects between you and the airbag 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 a irbag 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
cupholders, 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 object s.
Items can also move into the area of the side airbag or the front ..,

airbag dur ing braking or in a sudden maneuver . Objects ne ar the
airbags can become proje ctile s and cau se injury , particularly when
the seat is reclined .
& WARNING
The fine dust created when airbags deploy can cause breathing
p roblems for people with a history of asthma or other breathing
c onditions .
• To reduce the risk of breathing problems , those with asthma or
other respir atory cond itions 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 .•

Repair, care and disposal of the airbags
P arts of the airbag system are installed at many different p laces on
you r Aud i. Insta ll ing, r emoving, servic ing or repa iring a pa rt in an
area of the vehicle can damage a part of an airbag system and
p revent that sys tem from working pr operly in a c ollisi on.
There are some important things you have to know to ma ke sure
t h at the effective ness of the system will not be impai red and that
discarded co mponents do not cause injury or po llute the env iro n­
ment .
& WARNING
Improper care , servicing and repair procedures can increase the
risk of personal injury and death by pre venting 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. 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 , adju st, or change any parts of the airbag sy stem .
• 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 author ized Audi dealer or qual ified workshop .
• Never modify the front bumper or parts of the vehicle body .

you if you are wearing your safety belt and wearing it properly. This
is why you should always wear your safety belt, not just because the
law requires you to do so=>
page 179, "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
wi ll deploy at a sl ightly higher rate of dece leration than if the belt is
not being used . The refore, in a particular col lision , it is possible that
an airbag will not deploy at a seating position where the safety belt
is being used but wil l inflate at the position where the safety belt is
not being used.
Remember too , airbags w ill deploy only once and only in certain
kinds of accidents -your safety be lts are always there to offer
protection in those accidents in wh ich airbags are not supposed to
deploy or when they have already deployed, for exampl e 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 be lt. The airbag system works most effectively when used
with the safety belts . Therefore, always wear your safety belts
correctly.
It is impo rtant to remember that while the supplemental airbag
system is designed to reduce the likelihood of serious injuries, other
injuries , for example, swelling, bruising, a nd minor abrasions can
also be associated with airbags .

Side airbags
Description of side airbags
The airbag system can provide supplemental protecti on
to properly rest rained occupants.
Fi g. 200 Si de a ir b ag
lo ca tio n in th e driv er's
seat
The side airbags are located in the sides of the front seat backrests
=> fig. 200. They are identified by the word "AIRBAG".
The side a irbag sy stem ba sic ally con sis ts of :
• the electronic contro l 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 moni tored electronically to make cer tain that
it is functioning 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).
T he 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 colli­
sion. The airbag deploys only in side impacts and on ly when the
vehicle acceleration registered by the control unit is high enough. If
t his rate is below the reference va lue programmed into the contro l
unit, the side airbags will not be triggered, even though the car may
Safety first
Airbag sy ste m
be badly damaged as a result of the collision. It is not possible to
define an airbag triggering range tha t wi ll cover every possible
ang le of impact, since the circumstances wi ll 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 208, "Important safety
instructions on the side airbag system".
Aside from their norma l safety function, safety belts work to help
keep the driver or front passenger in posi tion in the event o f a side
collision so that the side airbags can provide protection.
The airbag system is
not a substitute for your safety belt. Rathe r, it
is part of the overall occupant restraint system in your vehicle.
Always remember that the side airbag system can only he lp to
protect you if you are wearing your safety belt and wear ing it prop­
erly. This is another reason why you should always wear your safety
belts, not just because the law requires you to do so=>
page 179,
"General notes".
It is important to remember that while the supp lementa l side airbag
system is designed to reduce the likelihood of serious injuries, other
inju ries, for e xample, swell ing, bruising, and minor abras ions can
also be associated with deployed side airbags. Remember too, side
airbags will deploy only once and on ly in certain kinds of accidents
- your safety be lts are a lways there to offer protection.
Vehicle damage, repair costs or even the lack of vehicle damage are not necessarily an indication of ove r-sensitive or fa iled airbag acti­
vation. In some collisions, both front and side airbags may inflate.
Remember too, tha t airbags w ill deploy only once and on ly in
certain kinds of collisions -your safety belts are always there to
offer protection 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 accele ration measured by the sens or
is too low
