Advanced front airbag system
Your veh icle is equipped w it h a front Advanced
A irbag System in compliance with U nited
States Federal Motor Vehicle Safety Standard
208 as applicab le at the time your vehicle was
manufactured.
The front Advanced Airbag System supple ments the safety belts to provide add it ional
p rotection fo r th e driver's and front passeng
e r' s heads and upper bodies in fronta l crashes.
The airbags in flate only in frontal impacts
when the vehicle dece le rat ion is high enough .
The front Advanced A irbag System for the
fro nt sea t occ upants is no t a subs titu te for
your safety bel ts. Ra ther, it is p art of t he over
all occupant restraint system in your veh icle.
A lways remember that the airbag system can
only help to protect yo u, if you are s itting up
right, wearing yo ur safety belt and wearing it
properly . This is why you and your passengers
must always be properly restrained, not just
because the law requires you to be .
The Advanced Airbag System in your veh icle
has been certified to meet the " low r isk" re
qu irements for 3 and 6 year-o ld childre n on
the passenge r side and very small adu lts on
A irbag system 143
the d river side . The low risk deployment c rit e
ria are intended to help reduce the risk of in
ju ry through interaction with the front airbag
that can occur, for example, by being too close to the steering wheel and instrument
panel when the airbag inflates.
In add ition, the system has been certified to
comply with the "s uppression" requirements
of the Safety Standard, to turn off the front
airbag for infants 12 months old and younger
who are res trained on the fro nt passenger

Advanced Airbag System components
The front passenger seat in your vehicle has a
l ot of very important parts of the Advanced
A irbag System in it. These parts incl ude t he
c a pac itive passenger de te ct ion sys tem, wir
ing, b racke ts, and more . The cont ro l uni t
monitors the system o n the front passenger

seat from doing its job in a crash .
The front Advanced Airbag System
consists of the following:
-Crash sensors in the front of the veh icle tha t
measure ve hicle acceleration/dece le ration
to provide information to the Advanced Air bag System about the severity of the crash.
A irbag system 145
- An elect ron ic contro l unit, with integrated
crash sensors fo r front and side impacts .
T he control un it "decides" whether to f ire

Repair, care and disposal of the airbags
Parts of the a irbag system are installed at
many different places on your Audi. Installing,
removing, servic ing or repairing a part in an
area of the vehicle can damage a part o f 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 tha t dis
carded components do not cause injury or po l
l ute the env ironment.
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 o r deploying
an airbag unexpected ly:
- Never cover, obstruct, o r change the
steering wheel ho rn pad or airbag cover
o r th e 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 ho rn pad or instrumen t
pane l, use only a soft, d ry cloth or one
mois tened w ith plain wate r. Solven ts or
cleaners co uld damage the airbag cover
or change the stiffness o r strength of the
A irbag sys tem 153
material so that the airbag cannot de
ploy and protect properly.
- Never repair, adjust, or change any parts
of the a irbag system.
- All work on the steering wheel, instru
ment panel, front seats or e lectr 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 bumper or pa rts
of the vehicle body.
- Always make sure that the s ide a irbag
can inflate without inte rfe rence:
- Never in.stall 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 a irbags
i nflate.
- Damage to the orig inal seat cove rs or
to the seam in the area of the side a ir
bag module must a lways be repaired
i mmediately by an author ized Audi
dealer.
- The airbag system can deploy on ly once.
After an a irbag has been deployed, it
m ust be replaced with new replacement
pa rts des igned and app roved espec ially
for your Aud i mo del ve rsion. Replace

Other things that can affect Advanced
Airbag performance
C hanging the vehicle's suspension system can
ch ange the way th at the Advanced A irbag Sys
tem pe rforms in a crash. For example, using
tire -rim combinations not app roved by Audi,
lowering the vehicle, changing the stiffness of
the suspension, incl uding the springs, s uspen
sion struts, shock absorbers etc. can change
the forces that are measured by the a irbag
sensors and se nt to the electron ic control
u ni t. Some suspension changes ca n, for exam
p le, increase th e forc e levels meas ure d by t he
se nsors a nd make the airbag system deploy in
crashes in w hich it would not dep loy if the
cha nges had not been ma de. Ot her kinds of
cha nges may reduce the force levels meas
ured by the sensors and prevent the airbag
from deploy ing when it sho uld.
The sen so rs in the safety belt buckle fo r th e
driver an d 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 ve
hicle deceleration than i f the safe
ty belt is not being used. Therefore, in a par
t icu lar coll is ion, it is possible that an airbag
will not deploy at a seat ing pos ition w here the
safety belt is be ing used but will inflate at the
pos ition where t he safety belt is not be ing
u sed. It is important that noth ing interfere
with the safety be lt buckles so that the s en
sors can send the correct info rmation abou t
sa fe ty belt use to the elec troni c con trol un it .
A WARNING
-Changi ng the vehicle's suspension includ
ing use of unapp roved tire -rim combina
tions can change Advanced Airbag per
formance and increase the r isk o f serious
personal injury in a crash.
- Never install suspension components
that do not have the same performance
characterist ics as the components orig i
na lly installed on your vehicle .
- Never use tire-rim combinations that
have not been approved by Audi.
Knee airbags
Description of knee airbags
Applies to vehicles : wi th knee airbags
The knee airbag system can provide supple
mental prot ection to properly restrained
front seat occupants.
Fi g. 14 5 Driver"s air bag
The driver knee airbag is in the instrument
panel underneath t he steering wheel
Q fig . 145, the airbag for the passenger is at
about the same height in the instrument pan-

How knee airbags work
Applies to vehicles: with knee airbags
The risk of injury to the leg area can be re
duced by fully inflated knee airbags.
Fig. 146 Inflated airbags protecting in a frontal colli·
s io n
The knee airbag system has been designed so
that the a irbags for the driver and front pas
senger deploy in certain but not all frontal
collisions.
If the front airbags deploy, the knee airbags
a lso 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
Q page 147,
fig . 143.
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. Important safety instructions on the
knee airbag system
Applies
to vehicles: with 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.
A 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 are 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
~ page 163, 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
Child Safety 165
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, ca refully read all of the
information on child safety and Advanced Air
bags and heed all of the applicable WARN
INGS. Make certain that the chi ld 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 ..,.
