seating position and have the airbag system inspected by your
authorized Audi dealer .
• A tight tether or othe r strap on a rearward-facing child
restraint attached to the front passenger seat can put too much
pressure on the weight-sensing mat in the seat and register more
weight than i s actually on the seat. The heav ier weight registered
can make the system work as though an adult were on the seat
and deploy the Advanced Airbag when it must be suppressed
causing serious or even fatal injury to the child .
• If, in ex ceptional circumstances, you must install a forward·
facing child restraint on the front passenger seat, always move
the seat into i ts rearmo st po sition in the seat's fore and aft adjust ·
ment range, as far away from the airbag as possible . The backrest
must be adjusted to an upright position. Make sure that the
PASSENGER AIR BAG OFF light comes on and stays on all the time
whenever the ignition is switched on.
& WARNING
• If the PASSENGER AIR BAG OFF light do es not go out when an
adult is sitting on the front passenger seat after taking the steps
de scribed above, make sure the adult i s properly seated and
restrained at one of the rear seating positions.
• Have the airbag system inspected by your authorized Audi
dealer before transporting anyone on the front passenger seat.
[ i ] Tips
If the we ight-sens ing mat in the front passenger seat detects an
empty seat, the front a irbag on the passenger side w ill be t urne d off,
and PASS ENGER AIR BAG OFF will stay on.•
Repair, care and disposal of the airbags
Parts of the a irbag system a re installed at many different p laces on
your Audi. Inst all in g, remov ing, servic ing or repa iring a part in an
area of the ve hicle can damage a part of an airbag system and preve nt
t ha t system from working pro perl y in a coll is ion.
T here are some important thi ngs you have to know to make sure that
the effectiveness of the system will not be impa ired an d that
discarded components do no t cause injury or poll ute the enviro n­
ment .
& WARNING
Improper care , servicing and repair procedures can increase the
risk of personal injury 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 cupholders or telephone
mountings to the surfaces covering the airbag unit s.
• For cleaning the horn pad or instrument panel, use only a soft,
dry cloth or one moistened with plain water. Solvent s or cleaners
could damage the airbag cover or change the stiffness or strength
of the material so that the airbag cannot deploy and protect prop·
erly .
• Never repair, adjust, or change any part s of the airbag system .
• All work on the steering wheel, instrument panel , front seats
or electrical sy stem (including the installation of audio equip·
ment , cellular telephones and CB radios, etc .) must be performed
by a qualified technician who ha s the training and special equip ·
ment necessary .
• For any work on the airbag system, we strongly re commend
that you see your autho rized Audi dealer or qualified workshop.
• Never modify the front bumper or parts of the vehicle body.

are wearing your safety belt and wear ing it properly . This is why you
should always wear your safety belt, not just because the law requires
you to do so::::>
page 190, "General notes".
The safety belt buckle for the driver and front seat passenger have
switches that tell the airbag control module if the safety belt is being
used or not. If the safety belt is being used, the knee airbag will
dep loy at a slightly higher rate of deceleration than if the belt is not
being used. Therefore, in a particular collision, it is poss ible that an
airbag will not deploy at a seating position where the safety belt is
being used but will inflate at the position whe re the safety be lt is not
being used.
Remember too, airbags w ill deploy only once and only in certa in kinds
of accidents -your safety belts are always there to offer protection in
t hose 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 wo rks most effective ly when used with
the safety belts. Therefore, always wear your safety belts correctly .
It is important to remember that while the supplemental airbag
system is desig ned to reduce the likelihood of serious injuries, other
injuries, for example, swe lling, bruis ing, and minor abrasions can
also be associated with airbags.
The knee airbag system basically consists of:
• Th e electronic control module
• T wo inflatable airbags (airbag and gas generator), 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 front-end collis ions when the decelerat ion measured by the
control unit is too low
• in s ide collisions
Safety first Vehicle OP-eration
Airbag system
• in rear-end collisions
• in rollovers
• in the event of a system ma lfunction (warning/indicator light illu­
minated)
=> page 14 .
& WARNING
• Safety belts and the airbag system can only provide protection
when occupants are in the proper seating position =>
page 209.
• If the airbag indicator light comes when the vehicle is being
used, have the system inspected immediately by your authorized
Audi dealer. The airbag may not work properly when the vehicle
acceleration in a side collision is high enough to deploy the airbag.

Side airbags
Description of side airbags
The airbag system can provide supplemental protection
to properly restrained occupants.
Fig. 203 Side airbag
location in the driver's
seat
The side airbags are located in the sides of the front seat backrests
=>
page 219, fig. 203. They are identified by the word "AIRBAG" .
The side airbag system basically consists of:
• the electronic control module and external side impact sensors
• the two side airbags located in the sides of the front backrests
• the airbag warning light in the instrument cluster.
The airbag system is monitored electronically to make certain that it
is functioning properly at all times. Each time you turn on the igni­
tion, the airbag system indicator light will come on for a few seconds
(self diagnostics) .
The side airbag system supplements the safety belts 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 collision. The
airbag deploys only in side impacts and only when the vehicle acceler­
ation registered by the control unit is high enough . If this rate is
below the reference value programmed into the control unit, the side
airbags will not be triggered, even though the car may be badly
Safety first Vehicle OP-eration
Airbag system
damaged as a result of the collision. It is not possible to define an
airbag triggering range that will cover every possible angle of impact,
since the circumstances will vary considerably between one collision
and another. Important factors include, for example, the nature
(hard or soft) of the impacting object, the angle of impact, vehicle
speed, etc.
=> page 220, "Important safety instructions on the side
airbag system" .
Aside from their normal safety function, safety belts work to help keep the driver or front passenger in position in the event of a side
collision so that the side airbags can provide protection.
The airbag system is
not a substitute for your safety belt. Rather, it is
part of the overall occupant restraint system in your vehicle. Always
remember that the side airbag system can only help to protect you if
you are wearing your safety belt and wearing it properly. This is
another reason why you should always wear your safety belts, not just
because the law requires you to do so=>
page 190, "General notes".
It is important to remember that while the supplemental side airbag
system is designed to reduce the likelihood of serious injuries, other
injuries, for example, swelling, bruising, and minor abrasions can
also be associated with deployed side airbags. Remember too, side
airbags will deploy only once and only in certain kinds of accidents -
your safety belts are always there to offer protection .
Vehicle damage, repair costs or even the lack of vehicle damage are
not necessarily an indication of over-sensitive or failed airbag activa­
tion. In some collisions, both front and side airbags may inflate.
Remember too, that airbags will deploy only once and only in certain
kinds of collisions -your safety belts are always there to offer protec­
tion in those accidents in which airbags are not supposed to deploy or
when they have already deployed.
The side airbag system will not deploy:
• when the ignition is turned off
• in side collisions when the acceleration measured by the sensor is
too low
• in front-end collisions

Advanced front airbag system and children
Your vehicle is equipped wi th a fron t "Adva nced Airbag Syste m" in
compliance with United States Federal Motor Vehicle Safety Standard
(FMVSS) 20 8 as app licable at t he time your ve hicle w as m anufa c­
tured.
Controls and equip­ ment Safety first Vehicle operation
T
he Advanced A irbag system in your veh icle has been ce rtified to
meet the "low-r isk" re quiremen ts fo r 3-and 6-ye ar old c hildre n on
t he passenger side and small ad ults o n the dr ive r side . The low r isk
deployme nt c riteria are intende d to reduce the risk of injury t hrough
in teraction with the airbag that can occ ur, for example, by being too
close to the steering w heel and i nstr ument panel when the ai rbag
inflates . In addi tion, the system has bee n certified to comp ly with the
"suppression" requirements of the Safety Sta ndard, to turn
off the
fr ont ai rbag for infan ts up to 12 month s w ho are rest rai ned on the
front passenger seat in child restraints t hat are listed in the Stan­
d ard .
Even thoug h your veh icle is eq uipped with an Advanced Airbag
system, a ll child ren, es pecially those 12 years and yo unger, should
always ride in the back seat pro perly r estra ined for the ir age and s ize.
T he airbag on the passenger si de makes the fro nt seat a potentially
dange rous place fo r a child to ride. The front seat is not the s afest
place for a c hild in a forward-facing c hild safety seat. It can be a very
dange rous place for a n infant or a larger ch ild in a rearward-fa cing
seat. •

and for the different models of the same kind of child restraint
offered by child restraint manufactu rers .
The weight ranges for the individual types, makes and models of ch ild
restraints that the NHTSA has specified in the Safety Standard
together with the weight ranges of typica l infants and typical 1 year­
old child have been stored in the control unit of the Advanced Airbag
System. When a child restraint is being used on the front passenger
seat with a typical 1 year-old chi ld, the Advanced Airbag System
compares the weight measured by the weight sens ing mat with the
information stored in the electronic control unit .
T he electronic control unit also registers the tension on the front
passenger safety be lt . The tension on the safety belt fo r the front
passenger seat will be different for an adult who is properly using the
safety belt as compared to the tension on the be lt when it is used to
attach a child restraint to the seat. The sensor below the latch for the
safety belt for the front seat passenger measures the tension on the
belt. The input from this sensor is then used with the we ight to
"decide", whether there is a child restraint with a typical 1 yea r-old
child on the front passenger seat and whether or not the airbag must
be turned off.•
Child restraints and Advanced Airbags
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 manufacturer for use with an
airbag . Always be sure that the child restraint is properly installed at
one of the rear seating positions. If in exceptional circumstances you
must use it on the front passenger seat, carefully read all of the infor­
mation on chi ld safety and Advanced Airbags and heed a ll of the
applicable WARNINGS. Make certain that the child restraint is
correctly recognized by the weight-sensing mat inside 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 restra ints have been available over
the years, new mode ls are introduced regularly incorporating new
and improved designs and older models are taken out of production .
Chi ld 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 chi ld restraint that
sits on the seat, whe n 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 sold in the past or w ill be sold over the
course of the useful lif e of yo ur vehicle.
For this reason, the United States National H ighway Traffic Safety
Administration has published a list of specific type, makes and
mode ls of child restraints that must be used to cert ify comp liance of
the Advanced Airbag System in your vehicle with the suppression
requirements of Fede ral Motor Vehicle Safety Standa rd 208. These
child restraints are:

Important safety instructions for using
child safety seats
Correct use of child safety seats substantially reduces the
risk of injury in an accident!
As the driver, you are responsible for the safety of everybody
in the vehicle, especially children:
- Always use the right child safety seat for each child and
always use it properly::::>
page 227.
- Always carefully follow the child safety seat manufac­
turer's instructions on how to route the safety belt prop­
erly through the child safety seat.
- When using the vehicle safety belt to install a child safety
seat, you must first activate the convertible locking
retractor on the safety belt to prevent the child safety seat
from moving ::::>
page 232.
-Push the child safety seat down with your full weight to
get the safety belt really tight so that the seat cannot
move forward or sideways more than one inch (2.5 cm).
- If a strap or tether is being used to tie the child safety seat
to the front passenger seat, make sure that it is not so
tight that it causes the weight-sensing mat to measure more weight than is actually on the seat.
Always remember: Even though your vehicle is equipped with an
Advanced Airbag system, all children, especially those 12 years and
younger, should always ride in the back seat properly restrained for
their age and size . ..,
Vehicle care Do-it-yourself service Technical data

& WARNING (continued)
-Always move the front passenger seat into the rearmost
position of the passenger seat's fore and aft adjustment range,
and as far away from the airbag as possible before installing
the child restraint.
- Always make sure that nothing prevents the front
passenger's seat from being moved to the rearmost position in
its fore and aft adjustment range.
- Always make sure that the backrest is in the upright posi­
tion.
• Always buckle the child safety seat firmly in place even if a
child is not sitting in it. A loose child safety seat can fly around
during a sudden stop or in a collision.
• Always read and heed all WARNINGS whenever using a child
restrained in a vehicle is being used=>
page 190, "Safety belts",
~ page 200, "Airbag system" and~ page 222, "Child Safety".
& WARNING
To reduce the risk of serious injury, make sure that the
PASSENGER AIR BAG
OFF light comes on and stays on whenever a
child restraint is installed on the front passenger seat and the
ignit ion is switched on.
• Take the child restrain t off the front passenger seat and install
it properly at one of the rear seat positions if the PASSENGER AIR
BAG
OFF light does not stay on.
• Have the airbag system inspected by your authorized Audi
dealer immediately.
& WARNING
A child in a child restraint installed with the LATCH lower anchor­
ages or with the standard safety belt on the rear seat may play

& WARNING (continued)
with unused rear seat safety belts and become entangled
resulting in serious personal injury and even death.
• Always buckle unused rear seat safety belts out of reach of chil­
dren in child seats and properly activate the convertible locking

- Push the child safety seat down with your full weight to
get the safety belt really tight so that the seat cannot
move forward or sideways more than one inch (2.5 cm).
Infants up to about one year (20 lbs. or 9 kg) a re best protected in
special infant carriers and child safety seats designed for the ir age
group . Many exp erts believe that infants and small children should
r ide only in spec ial restraints in which the child faces the back of the
vehicle. These infant seats suppo rt the baby's back, neck and head in
a crash=> fig. 205.
The airbag on the passenge r side makes the front seat a potentially
dangerous place for a chi ld to ride. The front seat is not the safest
place for a ch ild in a forward-facing child seat. It is a very dangerous
place for an infant or a large r child in a rearward -fac ing seat.
& WARNING
Not using a child safety seat, using the wrong child safety seat or
improperly installing a
child restraint increases the risk of serious
personal injury and death
in a crash.
• Never install rear-facing child safety seats
or infant carriers on
the front passenger seat -even with an Advanced Airbag System.
A child will be seriously injured and can be killed when the
inflating airbag hits the child safety seat or infant carrier with
great force and smashes the
child safety seat and child against the
backrest, center arm rest,
door or roof => page 202, "Child
restraints on the front seat- some important things to know".
• Always install rearward-facing child safety seats
or infant
carriers on the rear seat.
• Never install a rearward-facing child restraint in the forward­
facing direction. Such restraints are designed for the special needs
of infants and very small children and cannot protect them
prop·
erly if the seat is forward-facing.
• If you must install a rearward facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on,
& WARNING (continued)
immediately install the rearward-facing child safety seat in a rear
seating position and have the airbag system inspected by your
authorized Audi dealer.
• Always read and heed all WARNINGS whenever using a child
restrained
in a vehicle is being used => page 190, "Safety belts",
