all applicable laws and regulations must be
observed. Your authorized Audi dealer is fa
miliar with these requirements and we recom
mend that you have your dealer perform this

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced A irbag System
performs in a crash. For example, using tire-rim
comb inat ions not approved by Audi, lowering the
vehicle, changing the stiffness of the su spension,
including the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
e lectronic control un it. Some suspension changes
can, for example, increase the force levels meas
ured 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 measured by
the sensors and prevent the airbag from deploy
ing when it should.
_& WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in
crease the risk of ser ious personal injury in a
crash.
- Never install suspens ion components that
do not have the same performance charac
teristics as the components originally instal
led on your veh icle.
- Never use tire-rim combinations that have
not been approved by Audi.
Airbag system
Knee airbags
Description of knee a irbags
Applies to vehicles: with knee airbags
The knee airbag system can provide supplemen
tal protection to properly restrained front seat
occupants .
Fig. 161 D river 's knee a irbag
T he driver knee airbag is in the instrument panel
underneath the steering wheel
¢fig.161, 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 dep loy, the knee airbags also
deploy in frontal collisions when the dep loyment
threshold stored in the control unit is met
¢ page 152 , 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 provide 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 a l
ways wear your safety belt, not just because the
law requires you to do so¢

Airbag system
Remember too, airbags will deploy only once and
only in certain kinds of accidents -your safety
be lts are always there to offer protection in those
accidents in which airbags are not supposed to
deploy or when they have already deployed, for
examp le 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 des igned to re
duce the likelihood of serious injuries, other inju
ries, for example, swelling, bruising and minor
abrasions and friction burns can also occur when
an airbag inflates.
The knee airbag system basically consists of:
-The electronic control modu le
- Two inflatable airbags (airbag and gas genera-
tor), 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 switched off
- in frontal collisions when the deceleration
measured by the control unit is too low
- in s ide collisions
- in rear-end collisions
- in rollovers
- in the event of a system malfunct ion (warning/
indicator light is on) ¢
page 18.
.&, WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
the proper seating position
¢page 152.
-If the airbag indica tor lig ht ¢page 18
comes when the vehicle is being used, have
the system inspected immediate ly by your
authorized Audi dealer. It is possible that
the airbag will inf late when it is not sup
posed to, or w ill not inflate when it should.

How knee airbags work
App lies to vehicles: wi th kne e airbags
The risk of injury to the leg area can be reduced
by fully inflated knee airbags .
Fig. 162 Inflated airbags protect ing in a frontal collis ion
The knee airbag system has been designed so
that the airbags for the driver and front passen
ger dep loy in certain but not all fronta l co llisions .
If the front airbags deploy, the knee airbags also
deploy in frontal collisions when the deployment
threshold stored in the control unit is met.
When the system deploys, the airbags fill with a
propellant gas, and inflate between the lower
part of the instrument panel and the driver and
the lowe r part of the instrument panel and the
front passenger ¢
page 152, fig. 159.
Although they are not a soft pillow, they can
"c ushion" the impact and in this way they can
help to reduce the risk of injury to the lower ex
tremities .
A ll of this takes place in the blink of an eye, so
fast that many people don't even realize that the
airbags have deployed . The airbags also inflate
with a great deal of force and it is important for
occupant safety that nothing should be in their
way when they dep loy .
F ull y inflated airbags in combination with proper
l y worn safety belts s low down and limit the oc
cupant's forward movement and help to reduce
the risk of injury .

Important safety instructions on the knee
airbag system
Applies to vehicles: with k nee a irbags
Airbags are only supplemental restraint s. Always
wear safety belts correctly and ride in a proper
seating position.
There is a lot that you and your passengers must
know and do to help the safety belts and airbags
to prov ide supplementa l protection.
A WARNING
An inflating knee airbag can cause ser ious in
jury. Wearing safety belts incorrect ly and im
proper seating positions increase the risk of
serious personal injury and death whenever a
vehicle is being used.
- The knee airbag system cannot protect you
properly if you are seated too close to any of
the a irbag locat ions . When adjust ing their
seat positions, it is important that both the
dr iver and the front passenger keep the ir
upper bod ies and knees at the followi ng
mi nimum safe distances :
- at least 10 inches (25 cm) between the
chest and the steering wheel/instr ument
panel.
- at least 4 inc hes (10 cm) between the
knees and the lower part of the instru
ment panel.
- The risk of persona l injury increases if yo u
lean forward or to the s ide, or if the seat is
improperly pos it ioned and you are not wear
ing your safety belt . The risk increases even
more should the airbag deploy .
- Always make sure that the knee airbag can
inflate without inte rference . Objects be
tween you and the a irbag can increase the
risk of i nju ry i n an accident by inte rfe ring
w ith the way the ai rbag dep loys o r by be ing
pushed into you as the airbag dep loys.
- Never let anybody, especially ch ildren o r
animals ride in the footwell in front of the
passenger seat . If the airbag deploys, th is
can result in ser ious or fatal injuries .
- Never carry objects of any kind in the foot
well area in front of the driver's or pas
senger's seat . Bul ky objects (shopping
-
Airb ag system
bags, for examp le) can interfere with or
prevent proper deployment of the airbag .
Small objects can be thrown through the
vehicle if the airbag deploys and injure you
or your passengers.
- Make sure the re are no cracks , deep scratch
es o r other damage in the area of the instru
ment panel where the knee airbags are lo
cated .
- I f chi ldren are inco rrectly seated, their ris k
of injury increases in a coll is ion

How supplemental side airbags work
Side airbags deploy instantly and can help reduce the risk of upper torso injuries for occu
pants who are properly restrained.
Fig. 164 Inflated side a irbags on left side of veh icle, rea r
side airbag
When the system is triggered, the airbag is filled
with propellant gas and breaks through a seam in
the seat surface area marked "AIRBAG". It ex
pands between the side trim panel and the pas
senger . In order to help provide this additional
protection, the side airbag must inflate within a
fraction of a second at very high speed and with
great force. The supplemental side airbag could
injure you if your seating position is not proper or
upright or if items are located in the area where
the supplemental side airbag expands. This ap
plies especially to children
