Monitoring the
Advanced Airbag System
~ Airbag monitoring indicator light
Two separate indicators monitor the function
of the Advanced Airbag System : the airbag
monitoring indicator light and the
P ASS EN­
GER AIR BA G OFF
light .
The Advanced Airbag System (including the
electronic control un it, sensor circuits and sys­
tem wiring) is monitored continuously to make sure that it is functioni ng properly
whenever the ignit ion is on . Each time you
turn on the ignition , the airbag monitoring in­
d icator light
I will come on fo r a few seconds
(self diagnos tics) .
The system mu st be inspect ed when the
indicator light
I :
- does not come on when the ignit ion is
switched on,
- does not go out a few seconds after you
have switched on the ignition, o r
- comes on wh ile driving .
If an airbag system malfunction is detected,
the indicator light will first start flashing to
catch the driver's attention and then stay on
continuously to serve as a constant reminder
to have the system inspected immediately.
If a malfunction occurs that tur ns the front

Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
An airbag system that is not functioning
properly cannot provide supplemental pro­
tection in a frontal crash.
- If the airbag indicator light comes on, it
means that there may be someth ing
wrong with the Advanced Airbag System .
It is possible that the airbag will inflate
when it is not supposed to, or w ill not in­
flate when it should.
- Have the airbag system inspected imme­
diately by your Aud i dealer.
A WARNING
If the front airbag inflates, a ch ild without
a child restra int, in a rearward-facing child
safety seat or in a forward-facing chi ld re­
straint that has not been properly insta lled
wi ll be seriously injured and can be ki lled .
- Even though your veh icle is equipped
with an Advanced Airbag System, make certain that a ll children, especially 12
years and younger, a lways ride on the
back seat properly restrained for their
age and size.
- Always install forward or rear-facing
child safety seats on the rear seat -even
with an Advanced Airbag System.
- If you must install a rearward-facing
child safety seat on the front passenger
seat because of exceptional circumstan­ ces and the
PAS SENG ER AIR BAG OFF
light does not appear and stay on, imme-
A irbag system 12 1
diately install the rear- facing child safety
seat in a rear seat ing pos ition and have
the airbag system inspected by your Audi
deale r.
- A t ight tether or other strap on a rear­
ward-facing child restraint attached to
the front passenger seat can put too much p ressu re on the weight-sensing
mat in the seat and reg ister more weight
than is a ctually on the seat. The heavier
weight regis tered can make the system
wo rk as tho ugh an adult we re on the seat
and deploy the Advanced Airbag when it
m ust be suppressed causing serious or
even fata l injury to the ch ild.
- If, in exceptiona l circumstances, you
m ust install a forward-fac ing ch ild re­
straint on the front passenger seat, al­
ways move the seat into its rearmost po­
sition in the seat's fore and aft adjust­
ment range, as fa r away from the a irbag
as poss ible. The backrest must be ad just­
ed to an upright pos ition. Make sure that
the
PASSENGER AIR BAG OFF light
comes on and stays on all the time when­
ever the ignition is switched on .
A WARNING
-
-If the PASSENGER AIR BAG OFF light
does not go out when an ad ult is sitting
on the front passenger seat after taking
the steps described above, make sure the adu lt is properly seated and restra ined at
one of the rear seat ing pos itions.
- Have the airbag system inspected by
your Aud i dea ler before transporting
anyone on the front passenger seat.
(l) Tips
If the weight-sensing mat in the front pas­
senger seat detects an empty seat, the
front airbag on the passe nger side will be
turned off, and
PASSENGER AIR BAG OFF
will stay on.

122 Airbag system
Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different places on your Audi. Installing,
removing, servicing or repairing a part in an
area of the vehicle can damage a part of an
airbag system and prevent that system from
working properly in a collision.
There are some important things you have to know to make sure that the effectiveness of
the system will not be impaired and that dis­
carded components do not cause injury or pol­ 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 deploying when needed or deploying
an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel horn pad or airbag cover
or the instrument panel 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
panel, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners could 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 electrical sys­
tem (including the installation of audio
equipment, cellular telephones and CB
radios, etc .) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work­
shop. -
Never modify the front bumper or parts
of the vehicle body.
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags inflate.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can be activated only
once. After an airbag has inflated, it
must be replaced by an authorized Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only
once. After an airbag has been deployed,
it must be replaced with new replace­
ment parts designed and approved espe­
cially for your Audi model version. Re­
placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only.
Make sure that any airbag service action
is entered in your Audi Warranty & Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD.
- For safety reasons in severe accidents,
the alternator and starter are separated
from the vehicle battery with a pyrotech­ nic circuit interrupter.
- Work on the pyrotechnic circuit inter­
rupter must only be performed by a
qualified dealer -risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.

@ For the sake of the environment
Undeployed airbag modules and preten­
sioners might be classified as Perchlorate
Material -special handling may apply, see
www.dtsc.ca .gov/hazardouswaste/per­
chlorate. When the vehicle or parts of the
restraint system including airbag modules
and safety belts with pretensioners are
scrapped, all applicable laws and regula­
tions must be observed. Your authorized
Audi dealer is familiar with these require­
ments 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 Sys­
tem performs in a crash. For example, using
tire-rim combinations not approved by Audi,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag
sensors and sent to the electronic control
unit. Some suspension changes can, for exam­
ple, increase the force levels measured 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 meas ­
ured by the sensors and prevent the airbag
from deploying when it should.
The sensors in the safety belt buckle for the
driver and front passenger seat tell the elec­
tronic control module if the safety belt is
latched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high­
er rate of vehicle deceleration than if the safe­
ty belt is not being used. Therefore, in a par­
ticular collision, it is possible that an airbag
will not deploy at a seating position where the safety belt is being used but will inflate at the
position where the safety belt is not being
used. It is important that nothing interfere
with the safety belt buckles so that the sen-
Airbag system 123
sors can send the correct information about
safety belt use to the electronic control unit.
A WARNING
Changing the vehicle's suspension includ­
ing use of unapproved tire-rim combina­
tions can change Advanced Airbag per­
formance and increase the risk of serious personal injury in a crash.
- Never install suspension components
that do not have the same performance characteristics as the components origi­
nally installed on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.
A WARNING
-
Items stored between the safety belt
buckle and the center console can cause
the sensors in the buckle to send the
wrong information to the electronic con­
trol module and prevent the Advanced Air­
bag System from working properly.
- Always make sure that nothing can inter­ fere with the safety belt buckles and that
they are not obstructed.
Knee airbags
Description of knee a irbags
The knee airbag system can provide supple­
mental protection to properly restrained
front seat occupants.
Fig. 108 Dr iver's airbag
The driver knee airbag is in the instrument
panel underneath the steering wheel
~ fig. 108, the airbag for the passenger is at Ill>

124 Airbag sys te m
about the same height in the instrument pan ­
e l underneath the glove compartment.
The knee a irbag offers add it iona l pro tect ion
to the driver's and passenger 's knees and up­
per and lower thigh areas and supp lements
the protection by the safety be lts .
I f the front airbags deploy , the knee airbags
a lso deploy in frontal co llisions when the de­
p loyment thresho ld stored in the cont rol unit
is met ¢
page 117, More important things to
know about front airbags .
In addi tion to their normal safety function,
safety belts he lp keep the driver or front pas ­
senger in position in a frontal collisio n so that
the airbags can prov ide supplemental protec­
tion.
The airbag system is not a s ubstitute for yo ur
safety be lt . Rather, it is part of the overall oc ­
cupant restraint system in your veh icle. Al­
ways remember that the airbag system can
only help to protect you if you are wearing
your safety belt and wear ing it properly . Th is
i s why you shou ld always wear you r safety
be lt, not just because the law requires you to
do so ¢
page 100, General notes.
The safety belt buck le for the dr iver and front
seat passenger have switches that te ll the a ir­
bag control module if the safety belt is being
used or not. If the safety belt is being used,
the knee airbag will deploy at a slightly highe r
rate of deceleration than if the belt is not be­
ing used . Therefore, in a partic ular collision , it
is possible that an airbag will not deploy at a
seating position where the safety belt is being used but will inflate at the position where the
safety belt is not be ing used.
Remembe r too, airbags will deploy only once
and on ly in certain kinds of accidents -your
safety belts are always there to offer protec­
tion in those acc idents in which airbags are
n ot supposed to deploy or when they have a l­
ready deployed, fo r example whe n your veh i­
cle str ikes or is struck by another after the
fi rs t collis io n. This is
just one of the reasons why an airbag is
not a s ubstitute for the safety be lt. The airbag
system works most effect ively when used with
the safety belts. Therefore, always wear yo ur
safety belts correct ly.
It is important to remember that w hil e the
s u pplementa l knee airbag system is designed
to reduce the likelihood of ser ious injuries,
other injur ies, for example, swelling, bru is ing,
minor abrasions and friction bu rns can a lso
occur when an airbag inflates.
The knee airbag system basically consi sts
of:
- The e lectronic control module
- Two inflatable a irbags (a irbag and gas gen-
erator), one for the driver and one for the
front passenge r
- The a irbag ind icator light in the instrument
panel
The knee airbag sy ste m w ill not depl oy :
- when the ignition is t urned off
- in frontal collisions when the deceleration
measured by the contro l unit is too low
- in side co llisions
- in rea r-end co llisions
- in rollove rs
- in the event of a system malfunction (warn -
ing/ind icator light is on)
¢ page 15.
A WARNING
-Safety belts and th e airbag system can
only provide pro te ction when occupa nts
a re in the proper se ating posi tion

- If the airbag ind icator light come s when
the vehicle is be ing used, have the sys­
tem inspected immediate ly by yo ur au ­
thor ized A udi dealer.

How knee airbags work
The risk of injury to the leg area con be re­
duced by fully inflated knee airbags.
Fig. 109 Inflated airbags protecting in a fro ntal 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 117,
fig . 106.
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 125
Important safety instructions on the
knee airbag system
Airbags ore 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
improper 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

-Always install rear-facing child safety
seats on the rear seat.
- If you must install a rearward facing
child safety seat on the front passenger
seat in exceptional circumstances and
the
PASSENGER AIR BAG OFF light does
not come on and stay on, immediately
install the rear-facing child safety seat in
a rear seating position and have the air­
bag system inspected immediately by
your Audi dealer.
_& WARNING
If, in exceptional circumstances, you must
install a forward-facing child restraint on
the front passenger's seat:
- Always make sure the forward-facing
seat has been designed and certified by its manufacturer for use on a front seat
with a passenger front and side airbag.
- Always follow the manufacturer's in­
structions provided with the child safety
seat or carrier.
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible before installing
the child restraint. The backrest must be adjusted to an upright position .
- Always make sure that the
PASSENGER
AIR BAG OFF
light comes on and stays
on all the time whenever the ignition is
switched on.
(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 an "Advanced
Airbag System" in compliance with United
States Federal Motor Vehicle Safety Standard
Child Safety 131
(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 si ze. 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 .
Advanced Airbags and the weight­
sensing mat in the front seat
The Advanced Airbag System in your vehicle
detects the presence of an infant or child in a
child restraint on the front passenger seat us­
ing the weight -sensing mat in the seat cush­
ion and the sensor below the safety belt latch
on the front passenger seat that measures the
tension on the safety belt.
The weight -sensing mat measures total
weight of the child and the child safety seat
and a child blanket on the front passenger seat. The weight on the front passenger seat
is related to the design of the child restraint
and its "footprint", the size and shape of the
bottom of the child restraint as it sits on the ..,.

Fabrics and fabric coverings
Fabrics and fabric coverings (e .g. seats, door
trim panels, etc.) should be cleaned at regular
interva ls with a vacuum cleaner. T his removes
surface dirt particles which could become em­
bedded in the fabr ic through use. Steam
cleaners should not be used, because the
steam tends to push the dirt deeper into the
fabric and lock it there.
Norm al cleaning
Generally, we recommend using a soft sponge
or a lint-free microfiber cloth to the clean fab­
ric. Brushes should only be used for carpets
and floor mats, s ince other fabric surfaces
could be harmed by b rushes .
Normal surface sta ins can be cleaned using a
commercially available foam cleaner . Spread
the foam on the surface of the fabric with a
soft sponge and work it in gently . Do not satu­
rate the fabric. Then pat the foam d ry using
absorbent, dry cloths (e.g. microfibe r clo th)
and vacuum it afte r it has dr ied comp lete ly.
Cl eaning stains
Stains caused by beve rages (e .g. coffee, fruit
juice, etc.) can be t reated with a mild deter­
gent solution. App ly the dete rgent so lution
wi th a sponge. In the case of s tubbor n stains,
a detergent paste can be applied directly to

the stain and worked into the fabric. After ­
wards, use copious amounts of clean water to remove the rema in ing detergent. Apply the
water with a damp cloth or sponge and pat
the fabric dry with an absorbent, dry cloth.
Stains from choco late or makeup should have
detergent paste (e.g . ox-gall soap) rubbed in ­
to them. Afterwards, remove the soap with
water (damp sponge).
A lcohol can be used to treat stains from
grease, o il, lipstick or a ballpoint pen. Melted
grease or dye must be patted off using ab­
sorbent mater ial. It may be necessary to re­
treat the areas with detergent paste and wa­
te r.
In the case of genera l soiling of the uphols­
tery and cover material, we recommend hir ing
a specia list that has the equipment to clean
t h e seat covers and othe r fabr ic surfaces by
shampooing and spray extraction .
