Repair, care and disposal of the airbags
Pa rts of t he air bag system are i nstalled at many
d ifferen t places on your Aud i. Insta lling , remov­
ing, servi cing or repa iring a part in an area of the
ve hicle 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 mak e sure that the effectiveness of the
system wi ll not be impaired and that discarded
components do not cause injury or poll ute the
env ironment.
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-

¢ page 194, More important things to know
about front airbags .
In addition to their normal safety function, safe­
ty belts help keep the driver or front passenger in
posit ion in a frontal collision so that the airbags
can prov ide supplemental protection.
The airbag system is not a subst itute 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 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 176, Gener­
al notes .
Remember too, airbags will deploy only once and
only in certain k inds of accidents -your safety
be lts are always there to offer protection in those
accidents in which airbags are not supposed to
deploy or when they have a lready deployed, for
example when yo ur vehicle str ikes or is str uck by
anothe r after t he f irst collision .
This is just one of the reasons why an airbag is
n ot a substi tute for the safety belt. The airbag
system works most effectively when used with
the safety belts . Therefore , a lways wear your
safety be lts correct ly .
It is important to remember that while the sup­
p lemen tal knee a irb ag sys tem is designed to re­
duce the like lihood of serious injur ies, other inju­
ries, for example, swelling, bruising and minor
abrasions and friction burns can also occur when
an airbag inf lates.
The kn ee airbag sy stem basically con sist s of :
- T he elec tronic contro l module
- Two inflatab le airbags (airbag and gas genera -
tor), one for the drive r and one fo r the front
passenge r
- The airbag indicator light in the instrument
panel
The knee airbag s ystem will not deploy:
- when the ign ition is switched off

How knee airbags work
Applies to vehicles: wit h knee airbags
The risk of injury to the leg area can be reduced
by fully inflated knee airbags.
Fi g. 168 Inflated a irbags protect ing in a frontal coll is ion
The knee airbag system has been des igned 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 is io ns when the deployment
threshold stored in the cont rol un it is met .
When the system deploys, the airbags fill with a compressed 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

by airbags when they inflate, part icular ly when
the occupant sitt ing next to it is not seated prop­
erly. The s ide airbag for the front passenger seat
can be used with properly insta lled child re­

The side airbag system basically con sists of:
-the e lectron ic control modu le and externa l side
impact sensors
- the two airbags located in the sides of the front
backrests and the two airbags* located in the
rear backrest
- the a irbag warning light in the instrument clus-
ter .
T he airbag system is monitored electronically to
make certain that it is functioning properly at all
times. Each time you switch on the ign ition, the
airbag system indicato r light will come on for a
few seconds (self diagnostics).
The s ide airbag system supplements the safety
belts and can help to reduce the risk of injury to
the dr iver 's, front and rear passenger's upper tor ­
so on the side of the veh icle that is struck in a
side coll is ion . T he a irbag dep loys only i n side im­
pacts and o nly when the vehi cle acceleration reg­
i stered by the cont rol un it is h igh enough .
If this
rate is below the refe rence value programmed in­
to the cont rol unit, the side airbags wi ll not be
triggered , even thoug h the car may be bad ly
damaged as a result of the collision. It is not pos ­
sib le to define an airbag tr igger ing range that
will cover every possib le ang le of impact, s ince

-Safety belts and the a irbag system w ill only
provide protection when occupants are in
the proper seating position
¢ page 204 .
-If the airbag indicator light r::!;> page 21
comes when the vehicle is being used, have
the system inspected immediate ly 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 supplemental side airbags work
Side airbags deploy instantly and can help re­
duce the risk of upper torso injuries for occu­
pants who are properly restrained .
Fig. 170 Side impact protect ion : inflated s ide a irbags (ex ­
amp le)
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 s ide trim panel and the pas­
senger . In order to help provide this additional
protection, the side airbag must inflate within a
fract ion of a second at very high speed and with
great fo rce. The supplementa l side airbag could
injure you if your seating position is not proper or
upright or if items are located in the area where
the supplemental side airbag expands. This ap­ plies especially to children

safety .
Supplemental side airbags inflate be­
tween the occupant and the door pane l on the

Although they are not a soft pillow, they can
"cushion" the impact and in th is way they can

help to reduce the risk of injury to the upper part
of the body.
A fine d ust may develop when the a irbag dep loys.
This is norma l and does not mean there is a fire
in the vehicle.
Important safety instructions on the side
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 act according ly to he lp the safety belts
and airbags do their job to provide supplemental protect ion.
_& WARNING
An inflating side a irbag can cause serious or
fata l injury. Improperly wearing safety belts
and improper seating posit ions increase the
risk of serious persona l injury and death
whenever a vehicle is being used.
- In order to reduce the risk of injury when
the supplemental side airbag inflates:
- Always s it in an upr ight position and never
l ean against the area where the supple-
mental side airbag is located.
- Never let a child or anyone e lse rest their
head against the side trim panel in the
area where the supplementa l side airbag
i nflates .
- Always make sure that safety belts are
worn correctly,
- Do not let anyone s itting in the front seat
put their hand or any other parts of their
body out of the window .
- Always make sure that the side a irbag can
inflate without interference.
- Never ins tall sea t covers or replacement
u pholstery ove r the fron t seatbacks that
have not been specifica lly approved by
Audi.
- Never use additional seat c ushions that

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 airbag inflate.
- Always make sure that the side curtain air­
bags can inflate without interference .
- 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 a collision.
- Never use hangers to hang clothes on the
hooks.
- Only use factory-installed sun shades or, if
shades installed after the vehicle leaves the
factory, use only genuine Audi sun shades.
- Never swing the sun visors over to the side
windows if things such as pens, garage door
openers, hands-free speakers, etc . are at ­
tached to the sun visors. They could come
loose and cause serious injury if the side cur­
tain airbag inflates.
- A deploying airbag inflates in a fraction of a
second and with great force.
- Never attach objects to the cover or in the
deployment zone of a side curtain airbag.
- The airbag deployment zones must be kept clear at all times. Make sure there are no
objects, pets, or other persons in the space
between any vehicle occupant and any air­
bag at any time.
- Do not attach any accessories to the doors.

Child safety
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 airbag system inspected immediately by your Audi dealer .
A WARNING
-Forward-facing child seats installed on the
front passenger seat may interfere with the deployment of the airbag and cause serious
personal injury to the child.
- If exceptional circumstances require the use
of a forward-facing child restraint on the
front passenger's seat, the child's safety
and well-being require the following special
precautions to be taken:
- Always make sure that the forward-facing seat has been designed and certified by its
manufacturer for use on a front passenger
seat with a front and side airbag.
- Always carefully follow the manufacturer's
instructions provided with the child seat
or infant carrier.
- Never install a child restraint without a
properly attached top tether strap if the
child restraint manufacturer's instructions require the top tether strap to be used.
- Never put the forward-facing child re­
straint up against or very near the instru­
ment panel.
-Always set the safety belt upper anchor­
age to the adjustment position that per­
mits proper installation in accordance
with the child restraint manufacturer's in­
structions.
- 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 ad ­
justed to an upright position .
- 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 .
210
-Never place objects on the seat (such as a
laptop, CD player, electronic games de­
vice, power inverter or seat heater for
child seats) . These may influence the elec­
trical capacitance measured by the capaci­
tive passenger detection system and can
also fly around in an accident and cause
serious personal injury.
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat heat­
er for child seats) on the front passenger
seat if the device is connected to the 12-
volt socket or the cigarette lighter socket.
- If a seat heater has been retrofitted or
otherwise added to the front passenger seat, never install any child restraint sys­
tem on this seat.
- Make sure that there are no wet objects
(such as a wet towel) and no water or oth­
er liquids on the front passenger seat
cushion.
- Always make sure that the
PASSENGER
AIR BAG OFF
light comes on and stays on
all the time whenever the ignition is
switched on.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immediate­ ly install the forward-facing child seat in a
rear seating position and have the airbag
system inspected by your authorized Audi
dealer.
- Always buckle the child seat firmly in
place even if a child is not sitting in it. A
loose child seat can fly around during a
sudden stop or in a collision.

0 > co ,...., Advanced front airbag system and children
Your vehicle is equipped with a front "Advanced
Airbag System" in compliance w ith United States
F edera l Motor Vehicle Safety Standard ( FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 208 as applicable at the time
your veh icle 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 airbag inflates. In addition, the
system has been certified to comply with the
"s uppress ion " req uirements of the Safety Stand­
a rd, to turn off the front ai rbag for infants up to
12 months who are restrained on the front pas­
senger seat in child restraints that are listed in
the Standard.
E ven 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 restra ined for their age
and si ze. The airbag on the passenger side makes
the front seat a potentially dangerous place for a
child to r ide . 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
l arger child in a rearward -facing seat.
The vehicle's Advanced A irbag System has a ca ­
pac itive passenger detect io n system in the front
passenger seat cush ion that can detect the pres­
ence of a baby or a child in a ch ild restraint sys­
tem on this seat .
The capacit ive passenger detection system regis­
ters the changes that result in an electrical fie ld
when a ch ild, a child restra int, and a baby blanket
are on the front passenge r seat. The change in
the measured capacitance due to the presence of
a child, a child restraint, and a baby b lanket 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-
Ch ild safety
ies depending on the type of system and specific
make and mode l.
T he elect rical capac itance of the va rious types,
makes, and models of chi ld restra ints specified
by the U.S .National Highway Traff ic Safety Ad­
ministration (NHTSA) in the relevant safety
standard are stored in the Advanced Airbag Sys­
tem control unit together with the capacitances
typ ical of infants and a 1-year old child. When a
child restraint is used on the front passenger
seat w it h a typical 1 year-old infant, the Ad­
vanced Airbag System compares the capacitance measured by the capacitive passenge r detection
system with the data stored in the electronic co n­
t rol unit.
Child restraints and Advanced front airbag
system
Regardless of the ch ild restraint that you use,
make sure that it has been certified to meet Safe­
ty Standards and has been cert ified by its manu ­
facturer for use w ith an airbag . Always be sure
that the c hild rest raint is p roperly installed at
one of the rear seating positions . If in exception­
al circumstances you must use it on the front
passenge r seat, carefu lly read a ll of the informa­
tion on child safety and Advanced Airbags and heed all of the applicable WARNINGS . Make cer ­
tain that the chi ld and child restraint are correct­
ly recognized by the capac itive passenger detec­
t ion system in the front passenger seat, that the
front passenger a irbag is turned off, and that the
airbag status is always correctly s ignaled by the
PASSENGER AIR BAG OFF light .
Many types and models of child restra ints have
been available over the years, new models are in ­
troduced regu larly incorporating new and im­
proved designs and older models a re take n out of
production. Child restra ints are no t standa rdized.
Child res tra ints 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 th e seat, when they
are installed on a vehicle seat. These d ifferences
make it virtually impossib le to certify compliance
with the requirements for advanced a irbags w ith
each and every child restra int that has ever been ..,.
