-If liquid soaks into the front passenger seat,
this can keep the airbag system from work­
ing properly
and may, for instance,
deactivate
the passenger frontal airbag . If
this happens, the PASSENGER AIR BAG OFF
light will come on and stay on together with
the airbag indicator light fl in the instru­
ment cluster.
-
If liquid is pooled on the seat, but has not
soaked in, this may also keep the airbag sys­
tem from working properly and cause the
passenger frontal airbag to be enabled
(turned on), even though there is a properly
installed child
restraint system on the seat.
Wet towels or other wet things on the seat
cushion can have the same effect. If the
front passenger frontal airbag is turned on,
the PASSENGER AIR BAG OFF light light
will go
out.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the side
airbags supplement the protection offered by the
front three-point safety belts with pretensioners
and load limiters to help reduce the risk of injury
in a wide range of accident and crash situations.
Be sure to read the important information about
safety and heed the WARNINGS in this chapter.
Deployment
of the Advanced Airbag System and
the activation of the safety belt pretensioners de­
pend on the deceleration measured by the crash
sensors and registered by the electronic control
unit. Crash severity depends on speed and decel­
eration as well as the mass and stiffness of the
vehicle or object involved in the crash.
On the passenger side, regardless of safety belt
use, the front passenger frontal airbag will be
turned off ifthe electrical capacitance measured
by the capacitive passenger detection system on
the front passenger seat is less than the amount
programmed in the electronic control unit. The
front passenger frontal airbag will also be turned
off if the capacitance measured by the system for
the front passenger seat equals that of an infant
of about one year of age in one of the child seats
that was used to certify the Advanced Airbag Sys-
Airbag system
tern under Federal Motor Vehicle Safety Standard
208. The PASSENGER AIR BAG OFF light comes
on and stays on to tell you when the front Ad­
vanced Airbag System on
the passenger side has
been turned off c::;, page 200.
A WARNING
f-=
To reduce the risk of injury when an airbag in-
flates, always wear safety belts properly.
-
If you are unrestrained, leaning forward, sit­
ting sideways
or out of position in any way,
your risk
of injury is much higher .
-
You will also receive serious injuries and
could even be killed if you are up against the
airbag or too close to it when it inflates -
even with an Advanced Airbag ¢page 188.
More important things to know about front
airbags
Fig. 157 Inflated front airbags
Safety belts are important to help keep front
seat occupants in the proper seated position so
that airbags can unfold properly and provide sup­
plemental protection in a frontal collision.
The
front airbags are designed to provide addi­
tional protection for the chest and face of the
driver and the front seat passenger when:
-
safety belts are worn properly,
-
the seats have been positioned so that the oc-
cupant is properly seated as far as possible
from the airbag .
Because
airbags inflate in the blink of an eye with
great force, things you have on your lap or have
placed on
the seat could become dangerous pro­
jectiles, and
be pushed into you ifthe airbag in-
flates. .,..

When an airbag deploys, fine dust is released.
This is normal and is not caused by a fire in the
vehicle. This dust is made up mostly of a powder
used to lubricate the airbags as they deploy. It
could irritate skin.
It is important to remember that while the sup­
plemental airbag system is designed to reduce
the likelihood of serious injuries, other injuries,
for example swelling , bruising and minor abra­
sions, can also happen when airbags inflate. Air­
bags do not protect the arms or the lower parts
of the body. Front airbags supplement the three
point safety belts only in some frontal collisions
in which the vehicle deceleration is high enough
to deploy the airbags.
Front airbag s will not deploy:
-ifthe ignit ion is switched off when a crash oc-
curs,
-in side collisions,
-
in rear-end collisions,
-
in rollovers,
-
when the crash deceleration measured by the
airbag system is less than the minimum thresh­
old needed for airbag deployment as registered
by the electronic control unit.
The front passenge r airbag will also not
deploy:
-when the front passenger seat is not occupied,
-
when the electrical capacitance measured by
the capacitive passenger detection system for
the front passenger seat indicates that the pas­
senger side frontal airbag must be switc hed off
by the electronic control unit (the PASSENGER
AIR
BAG OFF light Q page 200 and how they
work comes on and stays on).
A WARNING
Sitting in the wrong position can increase the
risk of serious injury in crashes.
-To reduce the risk of injury when the airbags
inflate, the driver and passengers must al­
ways
sit in an upright position, must not
lean against or place any part of their body
too close to the area where the airbags are
located.
198
-Occupants who are unbelted, out of position
or too close to the airbag can be seriously
injured
by an airbag as it unfolds with great
force in the blink of an eye Q page 189.
A WARNING
A child in a rearward-facing child seat instal­
led
on the front passenger seat will be seri­
ously injured
and can be killed if the front air­
bag inflates -even with an Advanced Airbag
System.
-The inflating airbag will hit the child seat or
infant carrier with great force and will
smash the child seat and child against the
backrest, center armrest, door or roof.
- Always install rear-facing
child seats on the
rear seat.
- If you must install a rearward facing child
seat on the front passenger seat because of
exceptional circumstances and the PASSEN­
GER AIR BAG OFF light does not come on
and stay on, immediately install the rear­
facing child seat in a rear seating position
and have the airbag system inspected by
your Audi dealer.
A WARNING
Objects between you and the airbag will in­
crease the risk of injury in a crash by interfer­
ing with the way the airbag unfolds or by be­
ing pushed into you as the airbag inflates.
- Never hold
things in your hands or on your
lap when the vehicle is in use.
-
-Never transport items on or in the area of
the front passenger seat. Objects could
move in
to the area of the front airbags dur­
ing braking or other sudden maneuver and
become dangerous projectiles that can
cause serious personal injury if the airbags
inflate.
- Never place
or attach accessories or other
objects (such as cup holders, telephone
brackets, large, heavy or bulky objects) on
the doors, over or near the area marked
"AIRBAG" on the steering wheel, instru­
ment panel, seat backrests or between

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 -Two inflatable airbags (airbag and gas genera­
tor),
one for the driver and one for the front
passenger
-The airbag indicator light in the overhead con­
sole
The knee airbag syste m will not deploy:
-when the ignition is switched off
-in frontal collisions when the deceleration
measured by the control unit is too low
-
in side collisions
-
in rear-end collisions
-
in rollovers
-
in the event of a system mal function (warning/
i ndicator light is on) ~page 15.
A_ WARNING
-Safety belts and the airbag system can only
prov i
de protection when occupants are in
the proper seating position ~page 197.
-If the airbag indicator light~ page 15
comes when the vehicle is being used, have
the system inspected immediately 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 knee airbags work
The risk of injury to the leg area can be reduced
by fully inflated knee airbags.
Fig. 160 Inflated airbags protecting in a frontal collision
The knee airbag system has been designed so
that the airbags for the driver and front passen­
ger deploy in certain but not all frontal collisions.
Airbag system
If the front airbags deploy, the knee airbags also
deploy
in frontal collisions when the deployment
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 197, fig. 157.
Although they are not a soft pillow, they can
"cushion" the impact and in this way they can
help
to reduce the risk of injury to the lower ex­
tremities.
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 important for
occupant
safety that nothing should be in their
way when they deploy.
Fully inflated airbags
in combination with proper­
ly worn safety belts slow down and limit the oc­
cupant's forward movement and help to reduce
the risk of injury.
Important safety instructions on the knee
airbag system
Airbags are only supplemental restraints. Always
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 in­
j u
ry. Wearing safety belts incorrectly and im­
proper 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 adjusting their
seat positions, it is important that both the
driver and the front passenger keep their
upper bodies and knees at the following
minimum
safe distances: ~
205

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
~page 212, Child safety.

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>
