- Always
install rearward-facing child re­
straints 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
If, in exceptional circumstances, you must in­
stall a forward-fac ing chi ld restraint on the
front passenger's seat:
- Always make sure the forward-fac ing seat
has been designed and cer t ified by its man­
ufacturer for use on a fron t seat with a pas­
senger front and side airbag .
- Never
put the forward-facing child restraint
up against or very near the instrument pan­
el.
-Always move the passenger seat into its
rearmost position in the seat's fore and aft
adjustment range, as far away from the air­
bag as possible, before install ing the for­
ward-facing child
restraint. The backrest
must be adjusted to an upright positio n.
-Always make sure that there is nothing on
the front passenger seat that will cause the
capacitive passenger detection system in
the seat to signa l to the Airbag System that
the seat is occupied by a person when it is
not, or to signa l that it is occupied by some­
one who is heavier than the person actually
sitting on the seat. T he presence of addi­
tional objec ts could cause the passenger
fro nt airbag to be turned on when it should
be off, or could cause the airbag to work in a
way
that is different from the way it would
have worked
without the object on the seat.
- Make
sure that the PASSENGER AIR BAG
OFF light comes on and stays on all the time
whenever the ignition is switched on.
Airbag system
Advanced Airbag System components
The front passenger seat in your vehicle has a lo t
of ve ry important parts of the Advan ced Airb ag
System in it. These parts include the capacitive
passenger detection system, wiring, brackets,
and more. The control unit monitors the system
on the front passenger seat when the ignition is
switched on and turns the airbag indicator light
on when a malfunction in the one of the system
components is detected c> page 200. Because
the front passenger seat contai ns important
parts of the Advanced Airbag System, you must
take care to p revent it from being damaged.
Dam age to the seat m ay prevent the Advan ced
Airbag
System for 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 ve hicl e tha t
measure vehicle acceleration/deceleration to
prov ide information to the Advanced Airbag
System about the severity of the crash.
-
An electronic control unit, with integrated
crash sensors for front and side impacts. The
control un it "decides" whether to f ir e the front
airbags based on the information rece ived from
the crash sensors. The control unit also "de­
cides" whether the safety belt pretensioners
should be activated.
-
An Advanced Airbag with gas generator for the
driver inside the steering wheel hub .
-
An Adva nced Airbag with gas generator inside
the instrument panel for the front passenger.
- A
capacitive passenger detection system under­
neath the front passenger seat cove r. This sys ­
tem measures the electrica l capacitance of the
pe rson in the seat. The information registered
is sent continuous ly to the electronic control
u
nit to reg ulate deployment of t he front Ad­
vanced Airbag on
the passenger side.
-

- The
PASSENGER AIR BAG OFF light comes on
and stays on in the overhead console
¢page 200, fig. 158 and tells you when the
front Advanced Airbag on the passenger side
has
been turned off.
- A
sensor in the safety belt latch for the driver
and for
the front seat passenger that senses
whether that safety belt is latched or not and
transmits this information to the electronic
control unit.
A WARNING
Damage to the front passenger seat can pre­
vent the front airbag from working properly.
-
Improper repai r or disassembly of the front
passenger and drive r seat will prevent the
Advanced Airbag System from functioning
properly.
-Repairs to the front passenger seat must be
performed by qualified and properly trained
workshop personnel.
-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
working properly.
- 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.
- I f you
must use a child restraint on th e fron t
p a
ssenger seat a nd the child restrain t man­
ufacturer's instructions require the use of a
towel,
foam c u shion or something else to
properly position the child restraint, make
certain that the PASSENGER AIR BAG OFF
light comes on and stays on whenever the
child restraint is installed on the front pas­
senger seat.
-
If the PASSENGER AIR BAG OFF light does
not come on and stay on, immediately in­
stall child restraint in a rea r seating pos ition
and have
the airbag system inspected by
your Audi dea le r.
A WARNING
If the front passenger seat gets wet, dry it im-
mediately.

-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. .,..

could cause injury in a crash, especially
when the airbags inflate.
- Never recline
the front passenger's seat to
transport objects. Items can also move into
the area of the side airbag or the front air­
bag during braking or in a sudden maneu­
ver. Objects near the airbags can become
projectiles and cause injury, particularly
when the seat is reclined.
- Never place
or transport objects on the
front passenger seat. Objects on the front
passenger seat could cause the capac itive
sensor in the seat to signal to airbag system
that the seat is occup ied by a person when it
in fact is not, or that the person on the seat
is heavier than he or she actually is. The
change in electric capacitance because of
such objects can cause the passenger front
airbag to be turned on when it should be
off, or can cause the a irbag to work in a way
that is diffe rent from the way it would have
worked without objects on the seat.
- Always make sure that there is nothing on
the front passenger seat that will cause the
capaciti ve passenger detection system in
the seat to signal to the Airbag System tha t
the seat is occupied by a person when it is
not, or to signa l that it is occupied by some­
one who is heavier than the person actually
sitting on
the seat. The presence of an ob­
ject could cause the passenger front airbag
to be turned on when it should be off, or
cou ld cause the air bag to work in a way that
is different from the way it wou ld have
worked witho ut the object on the seat.
- Never tilt the front passenger seat backrest
forward when the vehicle is moving. An in­
flating airbag will force the backrest back­
ward and can injure rear seat occupants.
_&WARNING
The fine dust created when airbags deploy can
cause breathing problems for people w ith a
history
of asthma or other breathing condi­
tions.
Airba g system
- To reduce the ris k of breathing problems,
those with asthma or other respiratory con­
ditions should get fresh a ir right away by
getting out of the vehicle or opening win­
dows or doors.
-
If you are i n a collision in which airbags de­
p loy, wash your hands and face with mild
soap and water before eating.
-
Be carefu l not to get the dust into your eyes,
or into any cuts or scratches.
-Ifthe residue should get into your eyes,

Monitoring the
Advanced Airbag System
t~~ Airbag monitoring indicator light
Two separate indicators monitor the function of
the Advanced Airbag System: the airbag moni­
toring indicator light and the PASSENGER AIR
BAG OFF light.
The Advanced Airbag System as well as the side
airbags and side curta in airbags with ejection
mitigation features (including the electronic con­
trol unit, sensors and system wiring) are all
monitored continuously to make sure that they
are functioning properly whenever the ignition is
on. Every time you turn on the ign ition, the a ir­
bag system indica to r light II will come on for a
few
seconds ( function check).
The system must be inspected when the
indicator light II:
-does not come on when the ignition is sw itched
on,
-
does not go out a few seconds after you have
switched on the igni tion, or
-comes on while driving .
If an airbag system malfunction is detected, the
indicator light will first start flashing to catch the
driver's attention and then stay on continuously
to serve as a constant rem inder to have the sys­
tem inspected immediately.
If a malfunction occurs that turns the front air-
bag on

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>

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.
Q page 208, 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 Qpage 180, General notes.
It is important to remember that while the sup­
plemental side a irbag system is designed to re­
duce the lik eli hood 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 -
Airbag system
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 a irbags, side
curtain airbags and side airbags may be triggered
together.
A WARNING
--Safety belts and the airbag system will only
provide protection
when occupants are in
the proper seating position Q page 208.
-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 possible that
the airbag will inflate when it is not sup­
posed to, or will not inflate when it should.
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.

-If children are seated improperly, their risk
of injury increases in the case of an accident
¢page 212, Child safety.
-Never attempt to modify any components of
the airbag system in any way.
-
In a 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 re­
moved from the inside door panel and the
openings they leave have not been proper­
ly 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.
Airbag system
Side curtain airbags
Description of side curtain airbags
The side curtain airbag system can provide sup­
plemental protection to properly restrained oc­
cupants.
Fig. 163 Side curtain airbags, driver's side: side curtain air­
bag locat ion
The side curtain airbags are located on both sides
of the interior above the front and rear side win­
dows~ fig. 163. They are identified by the word
"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 resu lt 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 collis ion 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 210, How side curtain air­

A WARNING
-Safety belts and the airbag system will only
provide
protection when occupants are in
the proper seating position Q page 44,
Seats and storage.
-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 possible that
the airbag will inflate when it is not sup­
posed to, or will not inflate when it should.
How side curtain airbags work
Side curtain airbags can work together with side
airbags to help reduce
the risk of head and upper
t orso injuries for occupants who are properly re­
strained.
Fig. 164 Illustration of principle: Inflated side curtain air­
bags on
the left side
The side curtain airbags inflate between the oc­
cupant and the windows on the side of the vehi­
cle
that is struck in a side collision Q fig. 164.
When the system is triggered, the s ide curtai n
airbag
is filled with propellant gas and breaks
th rough a seam above the front and rear side
windows identified by the AIRBAG label. In order
to help provide this additional protection, the
side curtain airbag must inflate within the blink
of an eye at very high speed and with great force .
The
side curtain airbag could injure you if your
seating position is not proper or upright or if
items are located in the area where the supple­
mental side curtain airbag inflates. This applies
especially to children Qpage 212.
