-Never remove the front passenger or driver
seat from the vehicle.
- Never remove
the upholstery from the front
passenger seat.
-Never disassemble or remove parts from the
seat or disconnect wires from it.
- Never carry
sharp objects in your pockets or
put them on the seat. The capacitive pas
senger detection mat in the front p assenger
seat will not function properly if it is punc
tur ed.
- Never carry
things on your lap or carry ob
jects on the front passenger seat. Such ob
jects can influence the capacitance regis
tered by the capacitive passenger detection
system, so that incorrect information is pro
vided to the airbag control unit.
- Never
store items under the front passenger
seat. Parts of the Advanced Airbag System
under the passenger seat could be dam
aged, preventing them and the airbag sys
tem from working properly.
- Never place
seat covers or rep lacement up
holstery that have not been specifically ap
proved by Audi on the front seats.
196
-Seat covers can prevent the Advanced Air
bag System from recognizing child re
straints or occupants on the front passenger
seat and prevent the side airbag in the seat
backrest from deploying properly.
-If a seat heater has been retrofitted or oth
erwise added to the front passenger seat,
never install any child restraint system on
this seat.
-Never use cushions, pill ows , blankets, or
simila r items on the front passenger seat.
The additional laye rs p revent the capacit ive
p a
ssenger detecti on sys tem from accurately
measuring the capacitan ce of the child safe
ty seat and/or the person on the seat and
thus keep the Advanced Airbag System from

- Never pl
ace or use any electrica l device
(such as a
laptop, CD player, electronic
games device, power inverter or seat heater
for child seats) on the front passenger seat
if the device is connected to the 12-volt
socket or the cigarette lighter socket. Such
dev i
ces can influence the capac itance regis
tered by the capacitive passenger detection
system, so that incorrect information is pro
vided to the airb ag control unit.

-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

-If the PASSENGER AIR BAG OFF light does
not go off when an adult who is not very
small is sitti ng on the front passenger seat
after taking the steps described above,
make sure the adult is properly seated and
restrained at one of the rear seating posi
tions. Have the airbag system inspected by
your authorized Aud i dealer before trans
porting anyone on the front passenger seat.
A WARNING
An airbag system that is not functioning prop-
erly
cannot provide supplemental protection
in a frontal crash.
-
If the airbag indicator light Q page 15
comes when the vehicle is being used, have
the system inspected immediately by your
authorized Audi dealer. It is possib le that
the airbag will inflate when it is not sup
posed to, or will not inflate when it should.
A WARNING
If the front airbag inflates, a child without a
child
restrai nt, 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.
- Even
though your vehicle is equipped with
an Advanced Airbag System, make certain
that all children, especially 12 years and
younger, always ride on the back seat prop
erly
restrained for their age and size.
- Always install forward

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 a collision.
There
are some important things you have to
know to make sure that the effectiveness of the ~
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>

passenger. In order to help provide this addition
al 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 Q page 212, 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 Qfig. 162.
Although they are not a soft pillow, they can
"cushion" the impact and in this way they can
he lp
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 ore only supplemental restraints. Always
properly wear safety belts and ride in a proper
seating posit ion.
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.
A WARNING
An inflating side airbag can cause serious or
fatal injury. Improperly wearing safety belts
and improper seating positions increase the
r isk 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.
208
-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
have not been specifically approved by
Audi.
- 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 s ide 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
airbags or allow children or other passen
gers 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. ~
