app licable laws and regulations must be ob
served. Your authorized Audi dealer is familiar
w ith these req uirements and we recommend
that you have your dealer perform this service
for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System pe rforms in a crash. For examp le, using tire-r im
comb inat ions not approved by Audi, lowering the
veh icle, chang ing the stiffness of the suspens ion,
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 unit . Some suspension changes
can, for example, increase the force levels meas
ured by the sensors and make the airbag system
deploy in crashes in wh ich it would not deploy if
the changes had not been made . Other kinds of
changes may reduce the fo rce levels measured by
the sensors and prevent the airbag from deploy ing when it should.
A WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in
crease the risk of serious personal injury in a
crash.
- Never install suspens ion components that
do not have the same performance charac
teristics as the components or iginally instal
led on your veh icle.
- Never use tire-rim combinations that have
not been approved by Audi.
Airb ag sys tem
A WARNING
-Items stored between the safety belt buckle
and the center console can cause the sensors
i n the buckle to send the w rong information
to the electronic contro l modu le and prevent
the Advanced A irbag System from wo rking
p roperly.
- Always make sure that nothing can interfe re
with the safety belt buckles and that they are not obstructed.
Knee airbags
Description of knee airbags

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
always wear your safety belt, not just because
the law requires you to do soc::>
page 121, Gener
al information.
Remember too, airbags will deploy only once and
only 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
abrasions 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 indicator light in the instrument
panel
The knee airbag system will not deploy:
- when the ignition is turned off
- in frontal collisions when the deceleration
measured by the control unit is too low
- in side collisions
- in rear-end collisions
- in rollovers
144
- in the event of a system malfunction (warning/
indicator light is on)
c::> page 19.
A WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
the proper seating position
r::;> page 13 7.
- If the airbag indicator light
c::> page 19
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 will not inflate when it should.
How knee airbags work
App lies to vehicles: with knee airbags
The risk of injury to the leg area can be reduced
by fully deployed knee airbags.
Fig. 136 Inflated a irbags prot ectin g in a frontal coll is io n
The knee airbag system has been designed so
that the airbags for the driver and front passen
ger deploy in certain but not all frontal collisions.
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 lower part of the instrument panel and the
front passenger
c::> page 13 7, fig. 133.
Although they are not a soft pillow, they can
cushion the impact and in this way they can help
to reduce the risk of injury to the lower extremi
ties.

All of this takes place in the blink of an eye, so
fast that many peopl e 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 deploy .
Fully inflated airbags in comb ination with proper
ly worn safety belts slow down and limit the o c
cupant 's forward movement and help to reduce
the r isk of injury .
Important safety instructions on the knee
airbag system
Applies to vehicles: with knee airbags
Airbags are only supplemental restraints . 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 be lts and airbags
to provide supplemental protection .
& WARNING
An inflating knee airbag can cause ser ious in
jury. Wearing safety bel ts incorrec tly and im
proper seating positions increase the r isk o f
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 airbag locat ions. When adj usting their
seat positions, it is important that both the
driver and the front passenger keep their
upper bod ies a nd knees at the following
min imum safe distances :
- at least 10 inches (25 cm) between the
chest and the steering wheel/instrument
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 inc reases if you
lean forward or to the side, or if the seat is
improperly positioned and you are not wear
ing your safety belt. The r isk increases even
more should the a irbag deploy.
-
Airb ag sys tem
-Always make sure that the knee a irbag can
inflate w ithout interference. Objects be
tween you and the airbag can increase the
risk of injury in an accident by interfering
with the way the airbag deploys or by being
pushed into yo u as the a irbag deploys .
- Never let anybody, especia lly children or
anima ls ride in the footwell in front of the
passenger seat. If the airbag deploys, this
can result in serious or fatal in juries.
- Never carry objects of any kind in the foot
well area in front of the driver's or pas
senger's seat. Bulky objects (shopp ing
bags , for example) can interfere with or
prevent proper deployment of the airbag .
Small objects can be thrown through the
vehicle if the airbag dep loys and injure you
o r your passengers.
- Ma ke sure there a re no c racks, deep scratch
es o r othe r damage in the area of the i nst ru
men t panel where the knee airbags are lo
ca ted.
- If c hi ldren are incorrectly se ated, their ris k

The airbag system is monito red elect ronically to
make certa in that it is functioning properly at all
times. Each time you t urn on the ignit ion, the air
bag system ind icator light will come on for a few
seconds (self diagnostics).
The s ide a irbag system supplements the safety
be lts 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 col
lision. The airbag deploys on ly in side impacts
and only when the vehicle acceleration registered
by the control unit is high enough. If this rate is
below the reference value programmed into the
control u nit, the s ide a irbags will not be tr ig
gered, even though the car may be badly dam
aged as a result of the collision.
It is not possib le
to define an airbag triggering range that w ill cov

cumstances will vary considerably between one
collision and another. Important factors include,
for examp le, the nature (hard or soft) of the im

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.
F ig . 138 Inflated side airbags on left side of vehicle
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 additiona l
protection, the side airbag must inflate within a
fract ion of a second at very high speed and with
great force. The s upplemental side airbag cou ld
injure you if your seating position is not p roper or
upright or if items are located in the area where
the supplemental side airbag expands. This ap
plies especially to children

Important safety instructions on the side
curtain airbag system
Airbags are only supplemental restraints. Always
properly wear safety belts 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
do their job to provide supplemental protection.
A WARNING
Improperly wearing safety belts and improper
seating positions increase the risk of serious
personal injury and death whenever a vehicle
is being used.
- Never let occupants place any parts of their
bodies in the area from which the side cur
tain airbags inflate.
- Always make sure that the side curtain air
bags can inflate without interference. Un
suitable accessories fitted inside the expan
sion range of a head airbag can dangerously
interfere with its function. A deploying head
airbag develops enough force to catapult
any piece of add-on component out of its path of inflation and into the passenger
compartment. An occupant hit by such a
projectile can suffer serious injury or death
¢ page 246, Technical Modifications.
- Do not swivel the sun visors to the side if
you have any objects clipped onto them (for example pens).
If the airbag should deploy,
you could be injured by these objects.
- Use the built-in coat hooks only for light
weight clothing. Never leave any heavy or
sharp-edged objects in the pockets that may interfere with airbag deployment and can
cause personal injury in an accident.
150
- Never use hangers to hang clothing from
the hooks.
- Only use factory-installed sun shades or, in
the case of shades installed after the vehicle
leaves the factory, only Audi roll-up
sunscreens may be used
¢ page 246, Addi
tional accessories and parts replacement.
- Always sit in proper seating position and
wear safety belts while traveling so that the side curtain airbags can help provide protec
tion .
- The airbag system can only be triggered
once . If the airbag has been triggered, the
system must be replaced by an authorized
Audi dealer or qualified workshop.
-Always have work involving the side curtain
airbag system, removal and installation of
the airbag components, or other repairs performed by an authorized Audi dealer or
qualified workshop. Otherwise the airbag
system may not work correctly.
- Never attempt to modify any components of
the airbag system in any way.
