154 Airbag sys te m
- Always make su re that t here is nothing
on the front passenger seat that will
cause the capacitive passenge r detection
system in the seat to s ignal to the A irbag
System that the seat is occupied by a
person when it is not, or to signal that it
is occ upied by someone who is heavier
than the person actu ally s itting on the
sea t. The presence of additiona l obje cts
cou ld cause the passenger front airbag
to be t urned on when it sho uld be off, or
cou ld cause the airbag to work in a way
that is different from the way it wou ld
have worked without the object on the
seat.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes o n and stays on all the
t ime whenever the ignition is switched
on.
Advanced Airbag System components
The front passenger seat in your vehicle has a
l o t of very important pa rts of the Advanced
A irbag System in it. These parts incl ude the
capacitive passenger detect ion sys tem, wir­
ing, brac kets, and more . The cont ro l unit
monitors the system on the front passenger
seat when the ign ition is switched on and
turns the airbag indicator light on w hen a
malfunction i n the one of the system compo­
n ents is detected
c::;, page 159 . Because the
front passenge r seat contains important pa rts
of the Advanced Airbag System, you must
take ca re to pr even t it from be ing damaged.
Damage to the seat may preven t the Ad ­
vanced A irbag System for the front passenger
seat from doing its job in a crash .
The front Advanced Airbag System
consists of the following:
- Crash senso rs in the front o f the veh icle that
measure ve hicle acceleration/dece leration
to provide information to the Advanced Air­ bag System abo ut the severity of the crash .
- An electronic co ntro l unit, with i ntegrated
c rash sensors for f ront and side impacts.
The cont ro l unit "decides" whether to fire t
he front a irbags based on the in format ion
received from the crash sensors. The contro l
un it also "decides" whether the sa fety belt
pretens ioners sho uld be activated.
- An Advanced Airbag with gas generator fo r
the dr iver inside the steering wheel hub.
- An Advanced Airbag with gas gene rator in­
side the inst rument panel for the front pas­
senger.
- A capacit ive passenger detection system un­
derneath the front passenger seat cover.
This system measures the electrical capac i­
tance of the person in the seat. The informa­
tion registered is se nt cont inuous ly to the
elect ronic control un it to regu late deploy­
ment of the front Advanced A irbag on the
passe nger side.
- An airbag monitor ing system and indicator
light in t he i nstr ument cluster
¢ page 158.
-A senso r in each front seat registers the dis­
tanc e between the r espective seat and the
s teer ing whee l o r ins trumen t panel. The in­
form ation regis tered is sent cont inuo usly to
t he ele ct ron ic cont ro l unit to regula te de­
p loyment of the front Adv a need Ai rbags.
- The
PASSENGER AIR BAG OFF ligh t comes
on and stays on in the cen ter o f the instr u­
ment panel
c::;, page 214 and tells you when
the front Advanced Airbag on the passenger
side has been turned off.
- A sensor in t he safety be lt latch fo r th e d riv­
er and for the front seat passenger that
senses whether that safety belt is latched or not and transmits this information to t he
electronic control un it .
A WARNING
--
D amage to the fron t passenger seat can
p rev ent the fro nt airbag from wor king
prop erly.
- I mp rope r re pa ir or disassembly of the
fr ont passenge r and dr ive r sea t will pre­
ven t th e Adv anced Air bag System from
functioning p ro perly.
- Repairs to the front pa ssenge r seat must
be pe rformed by qualifie d and properly
trained workshop personnel.

www.dtsc.ca.gov/hazardouswaste/per­chlorate. When the vehicle or parts of the
restraint system includ ing airbag modules
and safety belts with pretensioners are
scrapped, all applicable laws and regula­
tions must be observed. Your authorized
Audi dealer is familiar with these require­
ments and we recommend that you have
your dealer perform this serv ice for you.
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 electron ic 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 .
A 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 characteristics as the components origi­
nally insta lled on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.

Knee airbags
Description of knee airbags
Applies to vehicles: wi th knee airbags
The knee airbag system can provide supple­
mental protection to properly restrained
front seat occupants.
Fig. 144 Driver 's kn ee airbag
The dr iver knee airbag is in the instrument
panel underneath the steering wheel
¢
fig. 144, the airbag for the passenger is at
about the same height in the instrument pan­
el underneath the glove compartment.
The knee airbag offers additional protection
to the driver's and passenger's knees and up ­
per and lower thigh areas and supplements
the protection provided by the safety belts.
If the front airbags deploy, the knee airbags
also dep loy in frontal collisions when the de­
ployment threshold stored in the control unit
is met¢
page 156, More important things to
know about front airbags.
In addition to their normal safety function,
safety belts help keep the driver or front pas­
senger in position in a frontal collision so that
the airbags can provide supplemental protec­
tion.
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overall oc­
cupant restraint system in your vehicle. Al­
ways remember that the airbag system can
only help to protect you if you are wearing
your safety be lt and wearing it properly. This
is why you should always wear your safety
belt, not just because the law requires you to
do so

not seated p roperly. The side airbag for the
front passenger seat can be used with proper­ l y installed ch ild restraints. Please be sure to
read the important information and warnings
whenever us ing a child restraint in a vehicle:
Safety belts¢
page 138, Airbag system
c:;, page 146, Child safety c:;, page 169.
The side airb ag system basically con sists of:
- the e lectronic control module and external
side impact sensors
- the two airbags located in the sides of the
front backrests
- the a irbag warn ing light in the inst rument
cluster .
The airbag system is monitored elect ron ica lly
to make certain that it is functioning prope rly
at all times. Each time you switch on the igni­
tion, the ai rbag system indicato r light will
come on for a few seconds (self diagnostics).
The s ide airbag system supp lements the safe­
ty belts and can help to reduce the risk of in­
jury to the driver's and front passenger's up­
per torso on the side of the vehicle that is
struck in a side co llision . The airbag deploys
only in s ide impacts and on ly when the veh icle
acceleration registered by the control unit is
h igh enough . If this rate is below the refer­
ence value programmed into the control un it,
the side airbags will not be tr iggered, even
though the ca r 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 o f impact, since the cir­
cumstances wi ll vary conside rably between
one co llision and another. Important factors
include, for example, the nature (hard or soft)
of the impacting object, the angle of impact ,
ve hicle speed, etc. ¢
page 167, Important
safety instructions on the side airbag system .
Aside from their normal safety function, safe­
ty belts work to he lp keep the driver or front
passenger in position i n the event of a side
coll is io n so that the side a irbags can provide
protection .
The airbag system is
not a substitute for your
safety belt . Rather, it is part of the overall oc -cu pant restraint system in you
r vehicle . A l­
ways 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 re ­
quires you to do so c:;,
page 138, General
notes.
It i s important to remember that w hile the
supplementa l side airbag system is designed
to reduce the likelihood of ser ious inju ries,
other injur ies, for example, swelling, bru is ing,
friction burns and m ino r abrasions can a lso be
associated w it h dep loyed side airbags. Re­
member too, side a irbags w ill dep loy on ly
once and on ly in certain kinds of accidents -
your safety belts are always the re to offer pro­
tection .
Vehicle damage, repair costs or even the lack
of ve hicle damage are not necessarily an indi ­
cation of over-sensitive or failed airbag activa­
t ion. In some col lisions, both front and side
airbags may inflate. Remember too, that air­
bags will deploy only once and only in certain
k inds of col lisions -your safety belts are al­
ways the re to offer p rotection in those acc i­
dents in which airbags are not supposed to
deploy or when they have a lready deployed .
The side airbag system will not deploy:
-when the ignit ion is switched off
- in side co llisions when the acceleration
measured by t he sensor is too low
- in front-end collisions
- in rear-end co llisions
- in rollove rs .
In some types of accidents the front airbags,
s ide cu rtain airbags and s ide a irbags may be
t rigge red togethe r.
_&. WARNING ~ ~
- Safety belts and the airbag system will
only provide protection when occupa nts
are in the proper seating position
