Repair , care and disposal of the airbags
Parts of the a irbag system are installed at many
d ifferent p laces on your Aud i. Installing, remov
ing, servic ing o r repa iring a part in an area of the
vehicle can damage a part of an airbag system
and p revent that system from working properly
in a co llision.
There are some important things you have to
know to make su re t hat the effectiveness of the
system w ill not be impaired and that discarded
components do not cause injury or pollute the
environment .
A WARNING
Improper care, serv icing and repa ir proce
dures can increase the r isk of personal injury
and death by preventing an airbag from de
ploying when needed or deploying an airbag
unexpectedly:
-
- Never cover, obstruct, or change the steer ing wheel horn pad or a irbag cover or the in
strument panel or mod ify them in any way.
- Never attach any objects such as cup holders or te lephone mountings to the su rfaces cov
er ing the airbag units.
- For cleaning the ho rn pad or instrument
pane l, use on ly a soft, dry cloth or one mois
tened with plain water. Solvents or cleaners cou ld damage the a irbag cover or change
the stiffness or strength of the mater ial so
that the airbag cannot dep loy and protect
properly.
- Never repair, adjust, or change any parts of
the airbag system.
- All work on the steering wheel, instr ument
pane l, front seats or electrical system (in
cluding the installation of audio equipment,
cellu lar telephones and CB rad ios, etc.)
must be performed by a qualified technician
Airb ag sys tem
who has the t raining and spec ial equ ipment
necessary.
- For any wo rk on the airbag system, we
strong ly recommend that you see yo ur au
thorized Audi dealer or qualified workshop.
- Never modify the front b umper or parts of
the vehicle body.
- Always make sure that the side a irbag can
inflate w ithout interference:
- Never ins tall seat covers or replacement
u pholste ry ove r the front seatbacks that
have not been specifica lly approved by
Audi.
- Never use addi tional seat cushions that
cove r the areas where the side airbags in
flate.
- Damage to the orig inal se at cove rs or to
the se am in the area of the s ide airbag
module must a lways be repaired immedi
ate ly by an authorize d Aud i dealer.
- The airb ag system can deploy on ly on ce. Af
ter an airbag has been deployed, it must be
replaced with new replacement parts de
signed and approve d espec ially for your

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
cha nge the way that the Advanced Airbag System
pe rforms in a crash. For example, using tire-r im
comb inat ions not approved by Audi, lower ing the
veh icle, changing the stiffness of the suspens ion,
including the spr ings, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic control unit . Some suspens ion 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 ki nds of
changes may reduce the force 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 A irbag performance and in
crease the risk of serious personal injury in a
crash.
- Never install suspension components that
do not have the same performance charac
teristics as the components originally insta l
led on your veh icle.
- Never use tire-rim comb inations that have
not been approved by Audi.

Knee airbags
Description of knee airbags
App lies to vehicles: with knee airbags
The knee airbag system can provide supplemen
tal protection to properly restrained front seat
occupants.
Fig. 160 Driver 's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering whee l
¢fig. 160, the
airbag for the passenger is at about the same
height in the instrument panel underneath the
glove compartment.
The knee airbag offers additiona l 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 a lso
deploy in frontal collisions when the deployment
threshold stored in the control unit is met
c> page 151, More important things to know
about front airbags .
In addition to their normal safety function, safe
ty belts help keep the dr iver 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 wear ing your safety belt
and wearing it p roperly. This is why you shou ld
always wea r your safety be lt, not just because
the law requires you to do so

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
examp le when your vehicle strikes or is struck by
another after the first collis ion.
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 correct ly .
It is important to remember that while the sup
plemental knee air bag system is designed to re
duce the likelihood of serious injuries, other inju
ries , for example, swelling, bruising and minor
ab rasions 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 switched off
-in frontal collisions when the deceleration
measured by the control unit is too low
- in side collisions
- in rear-end collisions
- in rollovers
- in the event of a system malfunction (warning/
indicator light is on)
cf;> page 18.
A WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
the proper seating position
cf;> page 151.
- If the airbag indicato r light c:::> page 18
comes when the vehicle is be ing us ed, have
the system inspected immed iately by your
authorized Audi dealer. It is possible that
the airbag will inf late when it is not sup
posed to, or will not inflate when it should.
Airbag system
How knee airbags work
App lies to vehic les : with knee airbags
The risk of injury to the leg area can be reduced
by fully inflated knee airbags .
Fig. 161 Inflated airbags protecting in a fronta l co llision
T he 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 coll isions 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 151, fig. 158.
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 ex
tremities.
All of th is takes place in the blink of an eye, so
fa st that many people don't even real ize that the
airbags have deployed. The airbags a lso 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 combination with proper
ly worn safety belts slow down and limit the oc
cupant's forward movement and help to reduce
the risk of injury.

Airbag syste m
Important safety instructions on the knee
airbag system
A pplies to veh icles: w ith knee a irbags
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 .
A WARNING
An inflating knee airbag can cause serious in
jury . Wearing safety belts incorrect ly and im
proper seating pos it ions increase the r isk 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 airbag locations. When adjusting their
seat positions, it is important that both the dr iver and the front passenger keep their
upper bod ies and 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 inches (10 cm) between the
knees and the lower part of the instru
ment panel.
- The risk of personal injury increases 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 risk increases even
more should the a irbag deploy.
- Always make sure that the knee airbag can
inflate without interference. Objects be
tween you and the airbag can increase the
risk of injury in an accident by interfer ing
with the way the a irbag dep loys or by being
pushed into you as the airbag deploys.
- Never let anybody, especially children or
animals ride in the footwell in front of the passenger seat . If the a irbag deploys, this
can result in serious or fatal injuries.
- Never carry objects of any k ind in the foot
well area in front of the driver's or pas
senger's seat . Bulky objects (shopping
1 6 0
bags, for example) can interfere with or
prevent proper deployment of the a irbag.
Small objects can be thrown through the
vehicle if the airbag deploys and injure you
or your passengers.
- Make sure there are no cracks, deep scratch
es or other damage in the area of the i nstru
ment panel where the knee airbags are lo
cated .
-If ch ildren are incorrectly seated, their risk
of injury increases in a coll ision

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
Fig. 162 Side airbag location in the driver"s seat
The side airbags are located in the sides of the
front seat backrests
c::;, fig. 162 and the rear back
rest fac ing 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 a irbags when they inflate, particu larly 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

It is important to remember that while the s ide
curtain airbag system is designed to help reduce
the likelihood of serious injuries, other injuries,
for example, swel ling, b ruising, fr iction burns
and minor abrasions can also be assoc iated with
these airbags upon deployment . Remember too,
these airbags will deploy only once and only in
certain kinds of acc idents -your safety be lts are
always there to offer protection.
The side curtain airbag system basically
consists of:
-The electronic control module and external side
impact sensors
- The side curtain airbags above the front and
rear side windows with ejection mitigation fea
tures
- T he airbag indicator light in the instrument
panel
The airbag system is monito red electronically to
make certa in it is funct ion ing properly at all
164
times. Each time you switch on the ignition, the
airbag system indicator light will come on for a
few seconds (se lf diagnostics).
The side curtain airbag is not activated:
-if the igni tion is sw itched off,
- in side collisions when the acceleration meas-
ured by the sensor is too low,
- in rear-end co llisions.
A WARNING
- Safety belts and the airbag system will only
provide protection when occupants are in
the proper seating position¢
page 53, Gen
eral information.
- If the airbag indicator light¢ page 18
comes when the vehicle is being used, have
the system inspected immediately by your
author ized 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 side curtain airbags work
Side curtain airbags can work together with side
airbags to help reduce the risk of head and upper
torso injuries for occupants who are properly re
strained.

Child safety
Advanced front airbag system and children
Your vehicle is equipped with a front "Advanced
Airbag System" in compliance with United States Federal Motor Vehicle Safety Standard (FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 208 as applicable at the time
your vehicle was manufactured.
The Advanced Airbag system in your vehicle has
been certified to meet the "low-risk" require
ments for 3- and 6-year old children on the pas
senger side and small adults on the driver side.
The low risk deployment criteria are intended to
reduce the risk of injury through interaction with
the airbag that can occur, for example, by being
too close to the steering wheel and instrument panel when the a irbag inflates. In addition, the
system has been certified to comply with the
"suppression " requirements of the Safety Stand
ard, to turn off the front airbag for infants up to
12 months who are restrained on the front pas
senger seat in child restraints that are listed in
the Standard.
Even though your vehicle is equipped with an Ad ·
vanced Airbag system, all children, especially
those 12 years and younger, should always ride in the back seat properly restrained for their age
and size. The airbag on the passenger side makes
the front seat a potentially dangerous place for a
child to ride . The front seat is not the safest place
for a child in a forward-facing child safety seat . It
can be a very dangerous place for an infant or a
larger child in a rearward-facing seat.
The vehicle's Advanced Airbag System has a ca
pacitive passenger detection system in the front
passenger seat cushion that can detect the pres
ence of a baby or a child in a child restraint sys
tem on this seat .
The capacit ive passenger detection system regis
ters the changes that result in an electrical field
when a child, a child restraint, and a baby blanket
are on the front passenger seat. The change in
the measured capacitance due to the presence of
a child, a child restraint, and a baby blanket on
the front passenger seat is related to the child restraint system resting on the seat. The meas
ured capacitance of a child restraint system var-
168
ies depending on the type of system and specific
make and model.
The electrical ca pacita nee of the various types,
makes, and models of child restraints specified
by the U.S .National Highway Traffic Safety Ad
ministration (NHTSA) in the relevant safety
standard are stored in the Advanced Airbag Sys
tem control unit together with the capacitances
typical of infants and a 1-year old child. When a
child restraint is used on the front passenger
seat w ith a typical 1 year-old infant, the Ad
vanced Airbag System compares the capacitance measured by the capacitive passenger detection
system with the data stored in the electronic con
trol unit.
Child restraints and Advanced front airbag
system
Regardless of the child restraint that you use,
make sure that it has been certified to meet Safe
ty Standards and has been certified by its manu
facturer for use with an airbag . Always be sure
that the child restraint is properly installed at
one of the rear seating positions. If in exception
al circumstances you must use it on the front
passenger seat, carefully read all of the informa
tion on child safety and Advanced Airbags and heed all of the applicable WARNINGS. Make cer
tain that the child and child restraint are correct ly recognized by the capacitive passenger detec
tion system in the front passenger seat, that the
front passenger airbag is turned off, and that the airbag status is always correctly signaled by the
PASSENGER AIR BAG OFF light .
Many types and models of child restraints have
been available over the years, new models are in
troduced regularly incorporating new and im
proved designs and older models are taken out of
production. Child restraints are not standardized.
Child restraints of the same type typically have
different weights and sizes and different "foot
prints", the size and shape of the bottom of the
child restraint that sits on the seat, when they
are installed on a vehicle seat. These differences make it virtually impossible to certify compliance
with the requirements for advanced airbags with
each and every child restraint that has ever been .,..
