one of the rear seating positions.
- Have the airbag system inspected by
your Audi dealer before transporting
anyone on the front passenger seat.
(D Tips
If the capacitive passenger detection sys
tem determines that the front passenger
seat is empty, the frontal airbag on the
passenger side will be turned off, and the
PA SSEN GER AIR B AG OFF light will stay
on .
Repair, care and disposal of the airbags
Parts of the a irbag system are installed at
many different places on your Audi. Installing,
removing, servicing or repairing a part in an
a rea of the vehicle can damage a part of an
airbag system and prevent that system from
working properly in a co llision.
There are some important things you have to know to make sure that the effect iveness of
the system will not be impaired and that dis
carded components do not cause injury or po l
lute the environment.
A WARNING
Improper care, servicing and repair proce
dures can increase the risk of personal in
jury and death by preventing an airbag from deploy ing when needed or deploying
an airbag unexpectedly:
- Never cover, obstruct, or change the steering wheel ho rn pad or airbag cover
or the instrument pane l or modify them
in any way .
- Never attach any objects such as cup
holders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
pane l, use only a soft, dry cloth or one
moistened w ith plain water. Solvents or
cleaners cou ld damage the airbag cover
or change the stiffness or strength of the material so that the airbag cannot de
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system.
- All work on the steering wheel, instru
ment panel, front seats or electr ica l sys
tem (including the installation of audio
equ ipment, cellu lar telephones and CB
radios, etc .) must be performed by a
qualified technic ian who has the training
and specia l equipment necessary.
- For any work on the airbag system, we strongly recommend that yo u see your
author ized Audi dealer or qualif ied work
shop.
- Never modify the front b umper or parts
of the vehicle body.
- Always make sure that the s ide airbag
can inflate without inte rfe rence:
- Never install seat covers or rep lace
ment upholstery over the front seat
backs that have not been specifically
approved by Audi.
- Never use additional seat c ushions that
cover the areas where the side airbags
inflate.
- Damage to the orig inal seat covers or
to the seam in the area of the side a ir
bag module must a lways be repaired
immediately by an author ized Audi
dealer .
- The airbag system can deploy on ly once.
After an a irbag has been deployed, it
must be replaced w ith new replacement
pa rts des igned and app roved especially
for your Aud i model version. Replace
men t of comple te airbag systems or air
bag components must be performed by
qua lified wor kshops only . Make sure that
any airbag service action is entered in
your Aud i Warranty
& Maintenance book
let under
AIRBAG REPLACEMENT RE
CORD.
- For safety reasons in severe accidents,
the alternator and starter a re separated
from the veh icle battery with a pyrotech-
n ic circuit inte rrupter . ..,.

-Work on the pyrotechnic circu it inter
rupter must on ly be performed by a
qualified technic ians who have the ex
perience, information and special tools necessary to perform the work safely.
- If the veh icle or the circuit interrupter
is sc rapped, all applicable safety pre
cautions must be followed.
@) For the sake of the environment
Undep loyed airbag modules and preten
sioners might be classified as Perchlorate Mate rial -special handling may apply, see
www.dtsc.ca .gov/haza rdo uswaste/per
chlorate. When the vehicle or parts of the
restrai nt system inclu ding airbag modules
a nd safety bel ts w ith pretens ioners are
scrapped, a ll applicable laws and regula
tions must be observed. Your authorized
Aud i dea ler is familiar w ith these require
ments and we recommend that you have
your dea ler perform this serv ice for you.
Other things that can affect Advanced
Airbag performance
C hanging the vehicle's suspension system can
ch ange the way that the Advanced A irbag Sys
tem pe rforms in a crash. For example, us ing
tire-rim combinations not app rove d by Audi,
lowe ring the vehicle, changing the stiffness of
the suspension, incl uding the springs, suspen
sion struts, shock absorbers etc. can change
the forces that are measured by the a irbag
se nsors and sent to the electron ic control
un it . Some suspension changes can, for exam
p le, increase the force levels measured by the
se nsors and make the airbag system deploy in
crashes i n w hich it would not dep loy if the
ch an ges had not been made. Ot her kinds of
cha nges may reduce the force levels meas
ured by the sensors and prevent the airbag
from deploying when it shou ld.
The senso rs in the safety belt buckle fo r th e
d river and front passenger seat tell the elec
tronic control module if the safety belt is
l atched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high-
A irba g sy stem 159
er rate of vehicle deceleration than i f the safe
ty belt is not being used. Therefore, in a par
ticu lar collis ion, it is possible t hat an airbag
will not deploy at a seating pos ition where the
safety belt is be ing used but w ill inflate at the
position w here the safety belt is not be ing
used. It is impo rtant that noth ing interfere
with the safety be lt b uckles so that the sen
sors can send the cor rec t info rmation abou t
sa fe ty belt use to the elec tronic con trol un it.
_&. WARNING ~-
Changing the vehicle's suspension includ-
ing use of unapprove d tire -rim combina
tions can change Advanced Airbag per
formance and increase the risk o f serious
personal injury in a crash.
- Never install s uspension components
that do not have the same performance
characteristics as the components origi
na lly installed on your vehicle .
- Never use tire-rim combinations that
have not been approved by Audi.
Knee airbags
Description of knee airbags
Appl ies to vehicles: wi th knee airbags
The knee airbag system can provide supple
mental prot ection to properly r estrain ed
front seat occupants.
Fi g. 14 8 Drive r's airbag
T he driver knee airbag is i n the instrument
panel underneath the steering wheel
i=> fig . 148, the airbag for the passenger is at
about the same height in the instrument pan-
el underneath the glove compartment . ..,_

How knee airbags work
Applies to vehicles: with knee airb ags
The risk of injury to the leg area can be re
duced by fully inflated knee airbags.
Fig. 149 Inflated airbags protecting in a frontal coll i
sio n
The knee airbag system has been designed so
that the airbags for the driver and front pas
senger deploy in certain but not all frontal
collisions .
If the front airbags deploy, the knee airbags
also deploy in frontal collisions when the de ployment 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¢
page 152,
fig. 146.
Although they are not a soft pillow, they can
"cush ion" the impact and in this way they can
help to reduce the risk of injury to the lower
extremities.
All 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 im
portant for occupant safety that nothing
should be in their way when they deploy.
Fully inflated airbags in combination with
properly worn safety belts slow down and lim
it the occupant's forward movement and help
to reduce the risk of injury.
Airbag system 161
Important safety instructions on the
knee airbag system
Applies to vehicles: wit h knee airbags
Airbags are only supplemental restraints . Al
ways 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 provide supplemental protection.
_&. WARNING .. -
An inflating knee airbag can cause serious injury. Wearing safety belts incorrectly and
imprope r 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 a re seated too close
to any of the airbag locations. When ad
justing their seat positions, it is impor
tant that both the driver and the front passenger keep their upper bodies and
knees at the following minimum safe
distances:
- at least 10 inches (25 cm) between the
chest and the steering wheel/instru
ment 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 wearing your safety belt . The risk in
creases even more should the airbag de
ploy.
- Always make sure that the knee airbag
can inflate without interference. Objects
between you and the airbag can increase
the risk of injury in an accident by inter
fering with the way the airbag deploys or
by being pushed into you as the airbag
deploys.
- Never let anybody, especially children
or animals ride in the footwell in front

166 Airbag system
-The side curtain ai rbags above the front and
rear s ide windows
- The airbag indicator light in the instrument
panel
The airbag system is monitored electron ica lly
to make certain it is f unct io ning properly at a ll
times. Each time you switch on the ignition,
the airbag system indicator light will come on
for a few seconds (self diagnostics).
The side curtain airbag is not activated:
- if the ignit io n is switched off,
- in s ide coll isions when the accelerat ion
measured by the sensor is too low,
- in rear-end collisions .
A WARNING

- If the airbag indica tor ligh t comes on
when the veh icle is being used, have the
system inspected immediately by your
authorized Audi dealer. The side curtain
airbag may not work properly even when
the vehicle acceleration in a side coll is ion
is h igh enough to activate the airbag .
How side curtain airbags work
Side curtain airbags can work togeth er with
side airbags to help reduce the risk of head and upper torso injurie s for occupants who
are properly res trained.

airbags o n th e left s ide
T he side curtain airbags inf late between the
occupant and the w indows on the sid e of the
vehicle that is struck in a side coll is ion
¢ fig . 153.
When the system is triggered, the side curtain
airbag is filled with prope llant gas and breaks
through a seam above the front and rear side
windows identified by the AIRBAG label. In or
der to he lp provide this additional protec tion,
the side curta in a irbag must inflate within the
blink of an eye at ve ry high speed and with
great fo rce . The side curta in a irbag could in
jure you if your seating posit ion is not prope r
o r u pright or if items are located in the area
where the supplemen tal side curta in airbag
inflates . This applies especially to chi ldren
c> page 168.
Althoug h they are not a so ft pillow, side cur
ta in airbags can "cushion" the impact and in
th is way they can help to reduce the risk of in
j u ry to the head and the upper part of the
body .
A f ine d ust may deve lop when the airbag de
ploys . This is qui te normal and does not mean
there is a fire in the veh icle .

1 70 Child Safety
c::> page 168, Important things to
know.
(D Tips
Always replace child restraints that were
installed in a vehicle during a crash. Dam
age to a child restraint that is not visible
could cause it to fail in another collision
situation.
Advanced front airbag system and children
Your vehicle is equipped with a front "Ad
vanced Airbag System" in compliance with United States Federal Motor Vehicle Safety
Standard (FMVSS) 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 " re
quirements for 3-and 6-year old children on
the passenger 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 airbag inflates. In addition, the system
has been certified to comply with the "sup
pression" requirements of the Safety Stand
ard, to turn off the front airbag for infants up
to 12 months who are restrained on the front
passenger seat in child restraints that are list
ed in the Standard.
Even though your vehicle is equipped with an
Advanced Airbag system, all children, espe
cially those 12 years and younger, should al
ways ride in the back seat properly restrained
for their age and size. The airbag on the pas
senger 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 for
ward-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
capacitive passenger detection system in the front passenger seat cushion that can detect
the presence of a baby or a child in a child
re
straint system on this seat.
The capacitive passenger detection system
registers the changes that result in an electri
cal 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 measured capacitance
of a child restraint system varies depending
on the type of system and specific make and
model.
The electrical capacitance of the various
types, makes, and models of child restraints
specified by the U.S.National Highway Traffic
Safety Administration (NH TSA) in the relevant
safety standard are stored in the Advanced
Airbag System 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 with a typical 1 year-old infant, the Advanced Airbag System compares
the capacitance measured by the capacitive passenger detection system with the data
stored in the electronic control 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
United States Federal Motor Vehicle Safety
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 excep
tional circumstances you must use it on the
front passenger seat, carefully read all of the
information on child safety and Advanced Air
bags and heed all of the applicable WARN
INGS. Make certain that the child and child re
straint are correctly recognized by the capaci
tive passenger detection system in the front passenger seat, that the front passenger air
bag is turned off, and that the airbag status is .,.

grease or dye must be patted off using ab
sorbent materia l. It may be necessary to re
treat the areas with detergent paste a nd wa
ter.
I n the case of genera l soiling of the uphols
tery and cover material, we recommend hiring
a specialist that has the equ ipment to clean
the seat covers and other fabric surfaces by
shampooing and spray extraction.
A WARNING
Always read and heed all WARNINGS and
the information
Q page 204.
Open Velcro fasteners on your clothing can
damage the seat cover. Please make sure
that Velcro fasteners are closed.
Plastic parts and instrument panel
Always use a clean cloth moistened in clear
water to clean these areas. For pers istent dirt
use an Audi approved
s olvent -fr ee plasti c
cleane r/pro te cta nt.
A WARNING
So lvents can change the properties o f
some plastics and make it ha rder for the
airbag to dep loy.
- Never clean the instr ument pane l o r the
s u rface of airbag modules with cleaning
products that contain solvents.
- Products containing solvents w ill make

Natural leather
Appl ies to vehicles: with natural leather
Audi makes great efforts to maintain the
properties, natural look and feel of interior
leather .
General
We offe r ma ny d iffe rent types of leathe r o n
ou r vehicles. Most are diffe rent types of nappa
l eather, which has a smooth surface and
comes in various colo rs .
T he intensity of the co lor determ ines the visu
al cha racteristics and appea ran ce. If the su r
f a ce of the leather has a typ ica l na tural look,
then the leather is a nap pa lea ther that has
been left in a relative ly natura l condition . This
leather offers particularly good comfort and
breathes well. Fine veins, closed grains, insect
bites, sk in fo lds, and subt le variations in color
rema in v isible. These character istics demon
strate that the mate rial is natural.
Natura l nappa leather is not covered by a co l
or finish. It is therefore more sens it ive to soil
ing and wear, which is someth ing you need to
conside r if ch ildren, animals or other factors
might prove to be part icu larly hard o n the
leat her .
By contrast, leather types that are covered by
a colo red finish layer are more durable. This
has a positive effect on the leather 's resist
