in fact is not, or that the person on the seat
is heavier than he or she actually is. The
change in electric capacitance because of
such objects can cause the passenger front
airbag to be turned on when it should be
off, or can cause the a irbag to work in a way
that is diffe rent from the way it would have
wor ked witho ut objects on the seat.
- Always make sure that there is nothing on
the front passenger seat that w ill cause the
capacit ive passenger detection system in
the seat to signa l to the Airbag System that
the seat is occupied by a person when it is
not, or to signa l that it is occupied by some­
one who is heavier than the person actua lly
sitting on the seat. The presence of an ob­
ject could cause the passenger front a irbag
to be t urned on when it should be off, or
cou ld cause the ai rbag to work in a way that
is d ifferent from the way it wou ld have
wor ked witho ut the ob je ct on the seat.
A WARNING
The fine dust create d when air bags deploy can
cause breathing problems for peop le w ith a
history of asthma or other breathing condi­
tions .
- T o reduce the risk of breathing problems,
those with asthma or other respiratory con ­
ditions should get fresh air right away by
gett ing out of the veh icle or opening w in­
dows o r doors.
- If you are in a collision in which airbags de­
ploy, wash your hands and face with mild
soap and water before eat ing.
- Be careful not to get the dust into your eyes,
or into any cuts or scratches.
- If the resid ue should get into your eyes,
flush them with water.

Repair, care and disposal of the airbags
Parts of the a irbag system are installed at many
d ifferent places on your Aud i. Instal ling, remov-
210
ing, servicing or repairing a part in an area of the
vehicle can damage a part of an airbag system
and prevent that system from work ing properly
i n a coll is ion.
There are some important things you have to know to make sure that the effectiveness of the
system will not be impaired and that discarded
components do not cause injury or pollute the
environment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal injury
and death by preventing an airbag from de­
p loying when needed or deploy ing an a irbag
unexpectedly:
-
- Never cover, obstruct, or change the steer­
ing wheel ho rn pad or airbag cover or the in­
strumen t panel or modify them in any way.
- Never attach any objects such as cup ho lde rs
or telephone mountings to the surfaces cov­
ering the a irbag un its.
- For cleaning the horn pad or instr ument
panel, use only a soft, dry doth or one mois­
tened w ith plain water. Solvents or cleaners
could damage the airbag cover or change
the st iffness or strength of the material so
that the airbag cannot deploy and protect proper ly.
- Never repair, ad just, or change any parts of
the airbag system.
- All work on the steering wheel, inst rument
panel, front seats or e lectr ica l system (in­
cluding the installation of audio equ ipment,
cellular te lephones and CB radios, etc.)
m ust be perfo rmed by a qualified techn ician
who has the training and spec ial equipment
necessary.
- For any work on the airbag system, we
strong ly recommend tha t you see you r au­
thori zed A udi dealer or qualified wo rkshop.
- Never modify the front bumper or pa rts of
the vehicle body.
- Always make sure that the side a irbag can
inflate w ithout interfe rence:

Airbag system
Knee airbags
Description of knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front seat
occupants.
Fig. 167 Driver's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering wheel¢
fig. 167, the
airbag for the passenger is at about the same
height in the instrument panel underneath the
glove compartment.
The knee airbag offers additional protection to
the driver's and passenger's knees and upper and
lower thigh areas and supplements the protec­
tion provided by the safety belts.
If the front airbags deploy, the knee airbags also
deploy in frontal collisions when the deployment
threshold stored in the control unit is met
¢ page 205, More important things to know
about front airbags.
In addition to their normal safety function, safe­
ty belts help keep the driver or front passenger in
position in a frontal collision so that the airbags
can prov ide supplemental protection.
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overall occu­
pant restraint system in your vehicle. Always re­
member that the airbag system can only help to
protect 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 189, Gener­
al notes.
212
Remember too, airbags will deploy on ly once and
on ly 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 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 works most effectively when used with
the safety belts. Therefore, always wear your
safety belts correctly.
It is important to remember that while the sup­
plemental knee airbag system is designed to re­
duce the likelihood of serious injuries, other inju­
ries, for example, swelling, bruising and minor
abras ions and friction burns can also occur when
an airbag inflates.
The knee airbag system basically consists of:
-The electronic control module
- Two inflatable airbags (airbag and gas genera-
tor), one for the driver and one for the front
passenger
- The airbag warning light in the instrument clus-
ter
The knee airbag system will not deploy:
-when the ignition is switched off
- in frontal collisions when the decelerat ion
measured by the control unit is too low
- in side collisions
- in rear-end co llisions
- in rollovers
- in the event of a system malfunction (warning/
ind icator light is on) ¢
page 14 .
&_ WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
the proper seating position ¢
page 205.
-If the airbag ind icator light¢ page 14
comes when the vehicle is being used, have
the system inspected immediately by your
authorized Audi dealer.
It is possible that
the airbag will inflate when it is not sup ­
posed to, or wi ll not inflate when it should.

Airbag system
prevent proper deployment of the airbag.
Small objects can be thrown through the
vehicle if the airbag deploys and injure you
or your passenger .
- Make sure there are no cracks, deep scratch­
es or other damage in the area of the instru­
ment panel where the knee airbags are lo­
cated.
- If children a re incorrect ly seated, their risk
of injury increases in a collision
c::> page 218, Child safety.
Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
F ig. 169 Side airbag locat ion in t he drive r's seat
The side airbags are located in the sides of the
front seat backrests
c::> fig. 169 facing the doors .
They are identified by the word "AIRBAG".
The side airbags installed for the front seating
positions have been designed and certified to
help reduce the risk of injury that can be caused
by airbags when they inflate, particularly when
the occupant sitting next to it is not seated prop­
erly. The side airbag for the front passenger seat
can be used with properly installed child re­
straints. Please be sure to read the important in­
formation and warnings whenever using a child
restraint in a vehicle: Safety belts
c::> page 189,
Airbag system c::>page 196, Child safety
c::> page 218 .
The side airbag system basically consists of:
- the electronic control modu le and external side
impact sensors
214
- the two side airbags located in the sides of the
front backrests
- the airbag warning light in the instrument clus-
ter.
The airbag system is mon itored electron ical ly to
make certain that it is functioni ng p roperly 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 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
and head on the side of the vehicle that is struck
in a side collision. The airbag deploys in side im­
pacts and only when the vehicle acceleration reg­
istered by the control unit is high enough. If this
rate is below the reference value programmed in­
to the control unit, the side airbags will not be
trigge red, even though the car may be badly
damaged as a result of the collision .
It is not pos­
sible to define an airbag triggering range that
will cover every possible angle of impact, since
the circumstances will vary conside rably between
one collision and another. Important factors in­
clude, for example, the nature (hard or soft) of
the impacting object, the angle of impact, vehicle
speed, etc.
c::> page 216, Important safety in­
structions on the side airbag system .
Aside from their normal safety function, safety
belts work to help keep the driver or front pas­
senger in position in the event of a side collision
so that the side airbags can provide protect ion.
The airbag system is
not a substitute for your
safety belt. Rather, it is part of the overall occu­
pant restraint system in your vehicle . Always re­
member that the side airbag system can only
help to protect you if you are wear ing your safety
belt and wear ing it properly. This is another rea­
son why you sho uld always wear your safety
belts, not just because the law requires you to do
so
c::> page 189, General notes.
It is impo rtant to remember that while the sup­
plemental side airbag system is desig ned to re­
duce the likelihood of ser ious injuries, other inju­
ries, for example, swelling, bruising , friction
burns and minor abrasions can also be associated ..,.

deployment of the a irbag and cause serious
persona l injury to the child .
- If except ional circumstances require the use
of a forward-facing child restraint on the
front passenger's seat , the child's safety
and well-being require the following special
precautions to be taken:
- Always make sure that the forward -facing
seat has been designed and cert ified by its
manufacture r fo r use on a front passenger
seat with a front and s ide a irbag.
- Always carefully follow the manufacturer's
instructions provided with the child seat
or i nfant car rier.
- Never p ut the fo rward-facing child re­
stra int up against o r very near the instru­
men t panel.
- Always move the front passenger seat to
the highest posit ion in the up and down
ad justment range and move it back to the
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible, before installing
the forward-facing ch ild restraint.
- Always make sure that the safety be lt up­
per anchorage is behind the child restra int
and not next to or in front of the child re­
stra int so that the safety belt will be prop­
erly positioned .
- Always make sure that nothing prevents
the front passenger's seat from be ing
moved to the rearmost posit ion in its fore
and aft adjustment range .
- Never place objects on the seat (such as a
laptop, CD p laye r, electronic games de­
vice, powe r inverter or seat heater for
child seats). These may influence the elec-
Ch ild safety
trical capacitance measu red by the capaci­
tive passenger detection system and can
also fly around in an accident and cause
serious personal injury.
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, powe r inverter or seat heat ­
er for child seats) on the front passe nger

Child seats
Infant seats
Babies and infants up to about one year old and
20 lbs or
9 kg need special rearward-facing child
restraints that support the back, neck and head
in a crash .
Fig . 17 1 Rearwa rd-facing infant seat, prope rly installed on
the passenger seat
.,. When us ing the vehicle safety belt to install a
child safety seat, yo u must first activate the
convertib le lo ckin g re tractor on the safety belt
to p revent the ch ild safety seat from moving
¢ page 227.
.,. Push the ch ild safety seat down with your full
weight to get the safety belt really tight so that
the seat cannot move forward and sideways
more than 1 in (2.5 cm).
Infants up to about one year (20 lbs or 9 kg) are
best protected in special infant carriers and child
safety seats designed for their age group. Many
experts be lieve that infants and small ch ildren
should ride only in special restraints in wh ich the
child faces the back of the vehicle . These infant
seats support the baby's back, neck and head in a
cr ash
¢fig. 171.
A WARNING
Not using a child sa fe ty seat, using t he wrong
chi ld safety seat or imprope rly inst alling a
chi ld restraint increases the risk of ser ious
personal injury and death in a crash.
- Never install a rear -fac ing ch ild rest raint in
the forward-facing direction. Such restraints
are des igned for the special needs of infants
and very small children and cannot protect
them proper ly if the seat is forward-facing.
