OFF 3%; ON @ light
The PASSENGER AIR BAG OFF %; ON @ light is
located in the headliner > fig. 160.
The PASSENGER AIR BAG OFF 3; light will come
on and stay on to tell you when the front Ad-
vanced Airbag on the passenger side has been
turned off by the electronic control unit. If the
bulb for the PASSENGER AIR BAG OFF 3; ON @
light burns out, the airbag indicator light ka will
come on to signal a malfunction in the Advanced
Airbag System. Although the burned-out bulb
will not change the way the front passenger's
frontal airbag works, it will no longer be possible
to use the PASSENGER AIR BAG OFF #7; ON ®
light to make sure that the airbag on/off status is
correct for the occupant on the front passenger
seat. Have the airbag system inspected immedi-
ately by your authorized Audi dealer.
The PASSENGER AIR BAG OFF 3; ON @ light
will blink for about 5 seconds when:
— the capacitive passenger detection system,
which switches the front seat passenger's fron-
tal Advanced Airbag on and off, detects a
change in the status of the front passenger
seat.
As soon as the PASSENGER AIR BAG OFF #¥; ON
® light stops blinking, always make sure that the
airbag status (on or off) as shown by the light is
proper for the age, size and electrical capacitance
of the person occupying the front passenger seat.
Always make sure that the safety belt for the
front passenger seat is properly fastened.
The PASSENGER AIR BAG OFF 3%; / PASSENGER
AIR BAG ON ® light will show the status of the
front seat passenger's frontal Advanced Airbag.
The PASSENGER AIR BAG OFF 3%; light:
— will come on if the front passenger seat is not
occupied;
— will come on if the electrical capacitance meas-
ured by the capacitive passenger detection sys-
tem for the front passenger seat equals the
combined capacitance of an infant up to about
one year of age and one of the rearward-facing
or forward-facing child restraints listed in Fed-
eral Motor Vehicle Safety Standard 208 with
which the Advanced Airbag System in your vehi-
cle was certified; For a listing of the child re-
straints that were used to certify your vehicle's

ZX WARNING
— If the status of the Advanced Airbag System
has changed while the vehicle is moving, the
PASSENGER AIR BAG OFF 7; ON @ light
blinks for about 5 seconds to catch the driv-
er's attention. If this happens, always stop
as soon as it is safe to do so and check the
steps described above.
— If the PASSENGER AIR BAG OFF %; light
does not go off when an adult who is not
very small is sitting on the front passenger
seat after taking the steps described above,
have the airbag system inspected by your
authorized Audi dealer before transporting
anyone on the front passenger seat.

ZA WARNING
An airbag system that is not functioning prop-
erly cannot provide supplemental protection
in a frontal crash.
— If the airbag indicator light > page 17
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.

ZA WARNING
If the front airbag inflates, a child without a
child restraint, or in a rearward-facing child
safety seat, or in a forward-facing child re-
straint that has not been properly installed
will be seriously injured and can be killed.
— 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 appear
and stay on, have the airbag system inspect-
ed by your Audi dealer.
— If, in exceptional circumstances, you must
install a forward-facing child restraint on
the front passenger seat, always move the
seat into its rearmost position in the seat's
fore and aft adjustment 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.

Z\ WARNING
If the PASSENGER AIR BAG OFF %; light does
not go out when an adult is sitting on the
front passenger seat after taking the steps
described above, have the airbag system in-
spected by your Audi dealer before transport-
ing anyone on the front passenger seat.
@) Tips
If the capacitive passenger detection system
determines that the front passenger seat is
empty, the frontal airbag on the passenger
side will be turned off, and the PASSENGER
AIR BAG OFF 3%; light will stay on.
Repair, care and disposal of the airbags
Parts of the airbag system are installed at many
different places on your Audi. Installing, remov-
ing, servicing or repairing a part in an area of the

vehicle can damage a part of an airbag system
and prevent that system from working properly
in acollision.
There are some important things you have to
know to make sure that the effectiveness of the
system will not be impaired and that discarded
components do not cause injury or pollute the
environment.

Z\ 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:
— 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

201

Airbag system


have not been specifically approved by Au-
di.
— Never use additional seat cushions that
cover the areas where the side airbags in-
flate.
— 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 complete
airbag systems or airbag components must
be performed by qualified workshops only.
Make sure that any airbag service action is
entered in your Audi Warranty & Mainte-
nance booklet under AIRBAG REPLACEMENT
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 interrupter
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.

Orme Mar eel e ce)
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
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
202
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.

Z\ 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. 161 Driver's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering wheel > fig. 161, the
airbag for the passenger is at about the same
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
=> page 196, 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 al-
ways wear your safety belt, not just because the
law requires you to do so > page 180, General
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
— Two inflatable airbags (airbag and gas genera-
tor), one for the driver and one for the front
passenger
— The airbag warning light in the instrument clus-
ter
The knee airbag system 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
— inthe event of a system malfunction (warning/
indicator light is on) > page 17.

ZA\ WARNING
— Safety belts and the airbag system can only
provide protection when occupants are in
the proper seating position > page 196.
— If the airbag indicator light > page 17
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.

Fig. 162 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.
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

Airbag system

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 > page 180,
Airbag system > page 187, Child safety
> page 211.
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 clus-
ter.
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).
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 col-
lision. The airbag deploys in side impacts and on-
ly when the vehicle acceleration 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 damaged as a result
of the collision. It is not possible to define an air-
bag triggering range that will cover every possi-
ble angle of impact, since the circumstances will
vary considerably between one collision and an-
other. Important factors include, for example,
the nature (hard or soft) of the impacting object,
the angle of impact, vehicle speed, etc.
= page 206, Important safety instructions on
the side airbag system.
Aside from their normal safety function, safety
belts work to help keep the driver or front pas-
senger 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 occu-
pant restraint system in your vehicle. Always re-
member 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 rea-
son why you should always wear your safety
belts, not just because the law requires you to do
so > page 180, General notes.
It is important to remember that while the sup-
plemental side airbag system is designed to re-
duce the likelihood of serious injuries, other inju-
ries, for example, swelling, bruising, friction
burns 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 activation. 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 switched off
— in side collisions when the acceleration meas-
ured by the sensor is too low
— in front-end collisions
—in rear-end collisions
—in rollovers.
In some types of accidents the front airbags, side
curtain airbags* and side airbags may be trig-
gered together.

Z\ WARNING
- Safety belts and the airbag system will only
provide protection when occupants are in
the proper seating position > page 206.

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.

B4S-0176



Applies to: vehicles with Power top
Fig. 165 Inflated side airbag on left side of vehicle
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 side trim panel and the pas-
senger. In order to help provide this additional
protection, the side airbag must inflate within a
fraction of a second at very high speed and with
great force. The supplemental 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 > page 211, Child
safety. Supplemental side airbags inflate be-

tween the occupant and the door panel on the
side of the vehicle that is struck in certain side
collision > fig. 164.
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 upper part
of the body.
A fine dust may develop when the airbag deploys.
This is normal 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 accordingly to help the safety belts
and airbags do their job to provide supplemental
protection.

Z\ WARNING
An inflating side airbag can cause serious or
fatal injury. Improperly wearing safety belts
and improper seating positions increase the
risk of serious personal injury and death
whenever a vehicle is being used.
—In order to reduce the risk of injury when the
supplemental side airbag inflates:
— Always sit in an upright position and never
lean against the area where the supple-
mental side airbag is located.
— Never let a child or anyone else rest their
head against the side trim panel in the
area where the supplemental side airbag
inflates.
— Always make sure that safety belts are
worn correctly,
— Do not let anyone sitting in the front seat
put their hand or any other parts of their
body out of the window.
— Always make sure that the side airbag can
inflate
without interference.
— Never install seat covers or replacement
upholstery over the front seatbacks that

4S1012721BA
Airbag system



have not been specifically approved by Au-
di.
— Never use additional seat cushions that
cover the areas where the side airbags de-
ploy.
— 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.
— Objects between you and the airbag can in-
crease the risk of injury in an accident by in-
terfering with the way the airbag unfolds or
by being pushed into you as the airbag in-
flates.
— Never place or attach accessories or other
objects (such as cup holders, telephone
brackets, or even large, bulky objects) on
the doors, over or near the area marked
“AIRBAG” on the seat backrests.
— Such objects and accessories can become
dangerous projectiles and cause injury
when the supplemental side airbag de-
ploys.
— Never carry any objects or pets in the de-
ployment space between them and the air-
bags or allow children or other passengers
to travel in this position.
— Always use the built-in coat hooks only for
lightweight clothing. Never leave any heavy
or sharp-edged objects in the pockets that
may interfere with side airbag deployment
and can cause personal injury in an accident.
— Always prevent the side airbags from being
damaged by heavy objects knocking against
or hitting the sides of the seatbacks.
— The airbag system can only be triggered
once. If the airbag has been triggered, the
system must be replaced by an authorized
Audi dealership.
— Damage (cracks, deep scratches etc.) to the
original seat covers or to the seam in the
area of the side airbag module must always
be repaired immediately by an authorized
Audi dealer.
— If children are seated improperly, their risk
of injury increases in the case of an accident
= page 211, Child safety.

— Never attempt to modify any components of
the airbag system in any way.
—Ina side collision, side airbags will not func-
tion properly if sensors cannot correctly
measure increasing air pressure inside the
doors when air escapes through larger, un-
closed openings in the door panel.
— Never drive with interior door trim panels
removed.
— Never drive when parts have been removed
from the inside door panel and the open-
ings they leave have not been properly
closed.
— Never drive when loudspeakers in the
doors have been removed unless the
speaker holes have been properly closed.
— Always make certain that openings are
covered or filled if additional speakers or
other equipment is installed in the inside
door panels.
— Always have work on the doors done by an
authorized Audi dealer or qualified work-
shop.


Side curtain airbags
Description of side curtain airbags
Applies to: vehicles with side curtain airbags
The side curtain airbag system can provide sup-
plemental protection to properly restrained oc-
cupants.

Fig. 166 Side curtain airbags, driver's side: side curtain air-
bag location
The side curtain airbags are located on both sides
of the interior above the front and rear side win-
dows > fig. 166. They are identified by the word >
207

Airbag system

“AIRBAG” on the windshield frame and the cen-
ter roof pillar.
The side curtain airbags contain features that
provide ejection mitigation to help prevent vehi-
cle occupants or parts of their bodies from being
completely or partially ejected from the vehicle
interior in certain side impacts and vehicle roll-
overs.
The side curtain airbag system supplements the
safety belts and can help to reduce the risk of in-
jury for occupants’ heads and upper torso. The
side curtain airbag inflates in side impacts and
only when the vehicle acceleration registered by
the control unit is high enough. If this rate is be-
low the reference value programmed into the
control unit, the side curtain airbag will not be
triggered, even though the car may be badly
damaged as a result of the collision. It is not pos-
sible 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 in-
clude, for example, the nature (hard or soft) of
the impacting object, the angle of impact, vehicle
speed, etc. > page 209, How side curtain airbags
work.
Aside from their normal safety function, safety
belts work to help keep the driver or front pas-
senger in position in the event of a collision so
that the side curtain airbags can provide protec-
tion.
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 another reason
why you should always wear your safety belts,
not just because the law requires you to do so
=> page 180, General notes.
It is important to remember that while the side
curtain airbag system is designed to help reduce
the likelihood of serious injuries, other injuries,
for example, swelling, bruising, friction burns
and minor abrasions can also be associated with
these airbags upon deployment. Remember too,
208
these airbags will deploy only once and only in
certain kinds of accidents - your safety belts are
always there to offer protection.
The side curtain airbag system basically
consists of:
— The electronic control module and external side
impact sensors
— The side curtain airbags above the front and
rear side windows with ejection mitigation fea-
tures
— The airbag indicator light in the instrument
panel
The airbag system is monitored electronically to
make certain it is functioning properly at all
times. Each time you switch on the ignition, the
airbag system indicator light will come on for a
few seconds (self diagnostics).
The side curtain airbag is not activated:
— if the ignition is switched off,
— in side collisions when the acceleration meas-
ured by the sensor is too low,
—in rear-end collisions.

Z\ WARNING
— Safety belts and the airbag system will only
provide protection when occupants are in
the proper seating position > page 50,
Front seats.
— If the airbag indicator light > page 17
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.
