A WARNING
Improper care, servicing and repair proce
dures can increase the risk of personal injury
and death by preventing an airbag from de
ploying when needed or deploying an airbag
unexpectedly:
- 1
-Never cover, obstruct, or change the steer
ing wheel horn pad or airbag cover or the in
strument panel or modify them in any way.
- Never
attach any objects such as cup holders
or telephone mountings to the surfaces cov
ering
the airbag units.
- For cleaning
the horn pad or instrument
panel, use only a soft, dry cloth or one mois
tened 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 deploy and protect
properly.
- Never repair,
adjust, or change any parts of
the airbag system.
-All work on the steering wheel, instrument
panel, front seats or electrical system (in
cluding
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 au
thorized Audi dealer or qualified workshop.
- 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 replacement
upholstery over the front seatbacks that
have not been specifically approved by
Audi.
- Never
use additional seat cushions that
cover the areas where the side airbags in
flate.
Airbag system
-Damage to the original seat covers or to
the seam in the area of the side airbag
module must always be repaired immedi
ately by an authorized Audi dealer.
-The airbag system can deploy only once. Af
ter an airbag has been deployed, it must be
replaced with new replacement parts de
signed and approved especially for your
Audi
model version. Replacement of com
plete airbag systems or airbag components
must be performed by qualified workshops
only. Make sure that any airbag service ac
tion is
entered in your Audi Warranty &
Maintenance booklet under AIRBAG RE
PLACEMENT RECORD.
-For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechnic circuit
interrupter.
-Work on the pyrotechnic circuit interrupt
er must only be performed by a qualified
technicians who have
the experience, in
formation and special tools necessary to
perform the work safely.
-
If the vehicle or the circuit interrupter is
scrapped, all applicable safety precautions
must be followed.
@ For the sake of the environment
Undeployed airbag modules and pretension
ers might be classified as Perchlorate Materi
al -special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlo
rate. When the vehicle or parts of the re
straint system including airbag modules and
safety belts with pretensioners are scrapped,
all applicable laws and regulations must be
observed. Your authorized Audi dealer is fa
miliar
with these requirements and we recom
mend 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 System
performs in a crash. For example, using tire-rim ..,.
203
Downloaded from www.Manualslib.com manuals search engine Airbag system
combinations not approved by Audi, lowering the
vehicle, changing the stiffness of the suspension,
including the springs, suspension 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 example, increase the force levels meas
ured 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 measured by
the sensors and prevent the airbag from deploy
ing when it should.
_&. WARNING
Changing the vehicle's suspension including
use
of unapproved tire-rim combinations can
change Advanced Airbag 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 instal
led on your vehicle.
- Never use tire-rim
combinations that have
not been approved by Audi.
Knee airbags
Description of knee airbags
The knee airbag system can provide supplemen
tal protection to properly restrained front
seat
occupants.
Fig. 159 Driver's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering wheel Q fig. 159, the
airbag for the passenger is at about the same
204
height in the instrument panel underneath the
glove compartment.
The knee airbag offers additional 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 also
deploy
in frontal collisions when the deployment
threshold stored in the control unit is met
Qpage 197, 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
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 wearing your safety belt
and wearing it properly. This is why you should
always wear your safety belt, not just be ca use
t h e law requires you
to do so~ page 180, Gener
al notes .
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
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 works most effectively when used with
the safety belts. Therefore, always wear your
safety belts correctly.
It is important to remember that while the sup
plemental knee airbag system is designed to re
duce the likelihood of serious injuries, other inju
ries, for example, swelling, bruising and minor
abrasions and friction burns can also occur when
an airbag inflates.
The knee airbag system basically consists of:
-The electronic control module .,.
Downloaded from www.Manualslib.com manuals search engine Airbag system
-at least 10 in (25 cm) between the chest
and the steering wheel/instrument panel.
-
at least 4 in (10 cm) between the knees
and the lower part of the instrument pan
el.
- 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 airbag 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 interfering
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 of the
passenger seat. If the airbag deploys, this
can result in serious or fatal injuries.
- Never carry
objects of any kind in the foot
well area in front of the driver's or pas
senger's seat. Bulky objects (shopping
bags, for example) can interfere with or
prevent proper deployment of the airbag.
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 instru
ment panel where the knee airbags are lo
cated.
-If children are incorrectly seated, their risk
of injury increases in a collision

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained front
seat occu
pants .
Fig . 161 Side airbag location in the driver's seat
The side airbags are located in the sides of the
front seat backrests Q fig. 161 facing 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 airbags when they inflate, particularly 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 Q page 180,
Airbag system Q page 188, Child safety
¢page 212.
The side airbag syste m b asica lly consist s o f:
-
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 overhead con
sole.
The airbag system is monitored electronically to
make certain that it is functioning properly at all
times. Each time you turn on the ignition, the air
bag system indicator light will come on for a few
seconds (self diagnostics). Iii>
Downloaded from www.Manualslib.com manuals search engine Child safety
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 airbag 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 ch ild restraint sys
tem on this seat.
The capacitiv e passenger detection system regis
ters the changes that resul t in an electrical field
when a ch ild , 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
ies
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 Ad-
214
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 with 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 Unit
ed States Federal Motor Vehicle Safety Standards
and ha s been certified by its manufacture r for
use with a n airbag. Always be sur e 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, care
fully
read all of the information on child safety
and Advanced Airbags and heed all of the appli
cable WARNINGS. Make certain that the child
and child restraint are correctly recognized by the
capacitive passenger detection system in the
front passenger seat, that the front passenger
airbag is turned off, and that the airbag status is
always correctly si
gnaled by the PASSENGER AI R
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 a nd 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
pr ints", 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
sold in the past or will be sold over the course of
the useful life of your vehicle.
For
this reason, the United States Nat ional High
way Traffic
Safety Administration has published a ..,_
