Advanced Airbag System components
The fron t passenger seat in your vehicle has a
lot of very important parts of the Advanced
Airbag System in it. These parts include the
weight-sensing mat, sensors, wiring, brack ­
ets, and more. The function of the system in
the front passenger seat is checked by the
e lectronic control u nit when the ignit ion is on .
The control un it mon itors the Advanced Air­
bag System and turns the airbag indicator
l ight on whe n a ma lfunction in t he sys tem
components is de tected. The function of the
airbag indicator light is described in greater
detai l below . Because the front passenger
seat contains important parts of the Ad ­
vanced A irbag System, you m ust 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 .
The front Advanced Airb ag Sy stem
consists of the following:
- Crash sensors in the front of the veh icle that
measure veh icle acceleration/decele ration
to provide information to the Advanced Air­
bag System about the seve rity of the crash.
- An electronic co ntrol unit, with integrated
c rash se nsors for front and side impacts .
T he cont ro l unit " decides " whethe r to fire
the front airbags based on the inform ation
received from the crash senso rs . The contro l
unit a lso "decides" whether the safety belt
pretensioners should be activated .

-Improper repair or disassembly of the
front passenger and driver seat will pre­
vent the Advanced A irbag System from
functioning properly.
- Repairs to the front passenger seat must
be performed by qualified and properly
trained workshop personnel.
- Never remove the front passenger or
dr iver seat from the veh icle .
- 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 things on your lap or carry
objects on the passenger seat. Such
items can increase the weight registered
by the weight-sens ing mat and send the
wrong info rmation to the airbag control
unit.
- Never store items under the front pas·
senger seat. Parts of the Advanced Ai r­
bag System under the passenge r seat
cou ld be damaged, prevent ing them and
the airbag system from wo rking proper­
ly .
- Never place seat covers or replacement upholstery that have not been specifical­
ly approved by A udi on the front seats.
- Seat covers can prevent the Advanced Airbag System from recognizing child re­
straints or occupants on the front pas­
senger seat and prevent the side airbag in the seat backrest from deploy ing prop­
erly.
- Never use cush ions, pillows, blankets or
similar items on the front passenger
seat. The add itiona l padd ing will prevent
the weight-sensing mat in the seat from
accu rately reg iste ring the c hild restra int
or person on the seat and prevent the
Advanced Airbag System from function­ ing properly .
-If you must use a child restra int on the
front passenger seat and the ch ild re- straint manufacturer's instructions
re­
qu ire the use of a towel, foam cushion or
something e lse to properly pos ition the
child restraint, make certain that the
PASSENGER AIR BAG OFF light comes
on and stays on whenever the ch ild re·
straint is installed on the front passen­
ger seat.
- If the PASSENGER AIR BAG OFF light
does not come on and stay on, immed i­
a tely insta ll child restrain t in a rear se at­
ing position and have the airbag system
inspected by your authorized Audi dealer.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
s ide airbags supp lement the protection of­
fered by the front three-point safety belts
with pretensioners and load limiters and the
adjustable head restraints to help redu ce the
risk of inju ry in a wide range of accident and
c rash situations. Be s ure to read the impor ­
tant information about safety and heed the
WARNINGS in this chapter.
Deployment of the Adv a need A irbag System
and the activation of the safety belt preten­
sioners depend on the deceleration measured
by the crash sensors and registered by the
electron ic control unit. The amount of infla­
tion of the front airbags can a lso be adapted
to the front seat pos ition, depending on the
distance between the respect ive front seat
and the steer ing w heel or instrument panel as
registered by sensors in the seats. Crash se·
verity depends on speed and deceleration as
well as the mass and st iffness of the vehicle
o r object involved in the crash .
On the passenger side, regardless of safety
belt use, the ai rbag w ill be tu rned off if the
we ight on the passenger seat is less than the
amount programmed in the e lectronic control
u nit. The front airbag on the passenger side
will a lso be turned off if one of the child safe -
ty seats that has been certified under Federal Motor Vehicle Safety Standard 208 has been
recogni zed on the seat . The

The Advanced Airbag System (includ ing the
e lectronic control unit, sensor circuits and sys­
tem wiring) is monitored continuously to
make sure that it is functioning properly
whenever the ignit io n is on . Each t ime you
turn on the ignition, the

(self diagnostics) .
The system mu st be inspect ed when the
I indicator light:
- does not come on when the ignit ion is
swi tched on,
- does not go out a few seconds afte r yo u
have switched o n the ignition, o r
- comes on w hile d riving .
If an airbag system malfunction is detected,
the indicator light will first start flashing to catch the driver's attention and then stay on
continuously to serve as a constant reminder
to have the system inspected immediately.
If a malfunction occurs that turns the front
a irbag on the passenger side off, the

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem performs in a crash. For example, using
tire-r im combinations not approved by Audi,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag sensors and sent to the electronic control
unit. Some suspension changes can, for exam­
ple, increase the force levels measured by the
sensors and make the airbag system deploy in
crashes in which it would not deploy if the
changes had not been made . Other kinds of
changes may reduce the force levels meas­
ured by the sensors and prevent the airbag
from deploying when it should .
The sensors in the safety belt buckle for the
d river and front passenger seat tell the elec­
tronic control module if the safety belt is
latched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high­
er rate of vehicle deceleration than if the safe ­
ty belt is not being used. Therefore, in a par­
ticular collision, it is possible that an airbag
will not deploy at a seating position where the safety belt is being used but will inflate at the
position where the safety belt is not being
used. It is important that nothing interfere
with the safety belt buckles so that the sen­
sors can send the correct information about
safety belt use to the electronic control unit.
.&_ WARNING
Changing the vehicle 's suspension includ­
ing use of unapproved tire-rim combina­
tions can change Advanced Airbag per­
formance and increase the risk of serious personal injury in a crash.
- Never install suspension components
that do not have the same performance
Airbag system 177
characteristics as the components origi­
nally installed on your vehicle .
- Never 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 information to the electronic con ­
trol module and prevent the Advanced Air­ bag System from working properly.
-Always make sure that nothing can inter-
fere with the safety belt buckles and that
they are not obstructed.
Knee airbags
Description of knee airbags
Applies to vehicles: wit h knee airbags
The knee airbag system can provide supple­

Fig. 179 Driver 's knee airbag
The driver knee airbag is in the instrument
panel underneath the steering wheel
Q fig . 179, the knee airbag for the passenger

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants .
Fig. 18 1 Side a irbag locat io n in the d river 's seat
The s ide airbags are located in the sides of the
front sea t bac krests
~ fig. 181. They are iden­
tified by the word "AIRBAG" .
The sid e airbag system basicall y consis ts of :
-the electronic control module and external
side impact sensors
- the two side airbags located in the sides of
t h e front backrests
- the a irbag warn ing light in the instrument
cluster.
The airbag system is monitored electronica lly
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 s ide airbag system supplements the safe­
ty belts and can help to reduce the risk of in­
jury to the drive r's and front passenger's up­
pe r torso on the side of the vehicle that is
struck in a side col lision . The airbag deploys
on ly in side impacts and on ly when the veh icle
acceleration registered by the control unit is h igh eno ugh . If this rate is below the refer­
ence va lue programmed into the control un it,
the side airbags will not be triggered,
even
though the car may be badly damaged as a re ­
sult of the collision. It is not possible to de ­
f ine an a irbag tr igger ing range that will
cover
every
possible angle of impact, since the cir­
cumstances w ill
vary considerably between one collision and another.
Important factors
incl ude, for example, the nature (hard or soft)
of the impacting object, the angle of impact,
vehicle speed, etc .
c:> page 181, Important
safety instructions on the side airbag system .
Aside from their normal safety function, safe­
ty 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 overa ll oc­
cupant restra int system in your vehicle . Al­
ways remember that the side airbag system
can only help to protect you if you are wea ring
you r safety belt and wea ring it p roperly . This
is anothe r reason why yo u should always wear
yo ur s afe ty be lts, no t ju st because the law re­
quires yo u to do so~
page 154, General
notes .
It is impo rtant to remembe r th at w hile the
s u pplementa l side airbag system is designed
to reduce the likelihood of ser io us inju ries,
othe r injuries, for example, swelling, br uising ,
and minor abrasions ca n also be associated
with deployed side airbags. Remember too,
s ide 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 ve hicle damage are not necessarily an ind i­
cation of over-sensitive or failed airbag activa­
t io n. In some coll is ions, both front and side
airbags may inflate . Remembe r too, t hat air­
bags will deploy only once and on ly in ce rtain
ki nds of col lisions -yo ur safety belts a re a l­
ways there to offer pro tection in those a cc i­
den ts in which airbags are no t su pposed to
deploy or when they have a lready deployed.
The side airbag system will not deploy:
- when t he ig nit ion is tu rned off
- in side co llisions when the acceleration
measured by the sensor is too low
- in front -end collisions
- in rear-end collisions
