General notes on airbag system
The airbag is an integral part of the car's passive
safety system.
In conjunction with the three-point seat belts,
the airbag system gives the front occupants
addi­

tional protection for the head and chest in the
event of a severe frontal collision.
In a severe side collision the side airbags and the
head-protection airbags reduce the risk of injury
to the occupants
•=>
A-
In addition to their normal function of protecting
the occupants in a collision, the seat belts also
hold them in a position where the airbags can in­
flate properly and provide maximum protection.
The airbag system will only work with the
igni­

tion on. The airbag system is monitored electron­
ically; the airbag warning lamp indicates whether
the system is functioning properly.
The main parts of the airbag system are:
-The electronic monitoring system (control unit
and sensors)
- The two front airbags
- The front side airbags
-The head-protection airbags
- The indicator Lamp
Q
in the instrument cluster
There is a fault in the airbag system if the
warning lamp
- does not come on when the ignition is switched

on.

- does not go out about 4 seconds after the
igni­

tion is switched on.
- goes out and then comes on again after the ig­
nition is switched on.
- comes on or flickers while the car is moving.

A WARNING
- The airbags are not a substitute for the seat

belts;
they are an integral part of the car's
overall passive safety system. The airbags
can only offer effective protection if the oc­
cupants are wearing their seat belts. For
this reason it is very important to wear the
seat belts at all times
^>page
275, Why is it
so important to use seat belts?.
The seat belts and airbags can only provide
maximum protection if the occupants are
seated correctly
^>page
58, Front seats.

•
If you do not wear a seat belt, if you lean

forward,
or are not seated correctly while
the vehicle is in motion, you are at greater
risk of injury should the airbag system be
triggered in an accident.
Components of the airbag system are loca­
ted in various parts of the vehicLe. If repairs
to other vehicle components make it neces­
sary to perform work on the airbag system
or to remove or install parts of the airbag

system,
this may cause damage to the air-
bag system. As a result, the airbags may not
inflate correctly or may not be triggered at
all in an accident situation. For this reason,
you should always have the work carried out
by a qualified workshop.
If a fault should occur in the airbag system,
have the system checked immediately by a
qualified workshop. Otherwise the system
may fail to trigger in an accident.
Do not attempt to modify components of
the airbag system in
anyway.

Never make any alterations to the front
bumper
or
the body.
Do not remove the front seats.
The airbag system can only be activated

once;
if the airbag has been triggered, the
system must be replaced. Should the airbag
system or airbag modules have to be re­

placed,
the qualified workshop carrying out
the replacement will document all details.

•
If any repair work is required
or
the airbag
and restraint systems have to be replaced,
have the work carried out by your authorised
Audi dealer or a qualified workshop which
adheres to the Audi factory standards. This
will minimise the risk of injury.
If you sell the vehicle, remember to pass on
the complete Service Wallet to the new
owner. If any of the airbags have been
281

Airbag system
deactivated, it is important that the new
owner is also given the relevant documents.
- The relevant safety requirements must be
observed when the vehicLe or components
of the airbag or belt tensioner systems are

scrapped.

When are the airbags triggered?
One or more airbag systems are triggered in se­
vere collisions, depending on the circumstances.
Factors determining the triggering response
It is not possible to define the exact triggering
response of the airbag system in all possible sit­
uations, since the circumstances in different
types of accident will vary considerably. Impor­
tant factors include, for example, the nature
(hard or soft) of the object which the car hits, the
angle of impact, vehicle speed and so on.
Whether the airbags are triggered depends
pri­

marily on the vehicle deceleration rate resulting
from the collision. By processing the signals from
the sensors Located in the vehicLe, the electronic
control unit is immediately able to evaluate the
severity of the collision and activate the restraint
systems accordingly. If the deceleration rate is
below the predefined reference value in the
con­

trol unit the airbags will not be triggered, even
though the accident may cause extensive damage
to the car. In these situations, the occupants are
protected by wearing the seat belts.

Note

The airbag may release a fine dust when it in­

flates.
This is quite normal and does not
mean there is a fire in the vehicle.

pending on the circumstances.
When the system is triggered, the airbags fill
with a propellant gas and open out in front of the
driver and front passenger
^>Fig.
230. In order to
provide the desired extra protection in an
acci­

dent, the airbags have to inflate extremely rapid­
ly (within fractions of
a
second). The fully de­
ployed airbags cushion the forwards movement
of the front occupants and help to reduce the risk
of injury to the head and the upper part of the
body.
Special openings in the airbag allow the gas to
escape at
a
controlled rate to restrain the for­
ward movement of the occupant's head and tor­

so.
Once the impact has been absorbed, the air-
bag deflates sufficiently for the front occupants
to see forward.

There are a number of safety points concerning
the airbag system which you should remember.
This will help to reduce the risk of injury in an ac­
cident.

25cm

Fig.
231 Minimum distance from steering wheel
A WARNING
- It is important for the driver and front pas­
senger to maintain a distance of at least
25 cm from the steering wheel or dash­
board
oFig.
231. The airbag system will not
be able to give the required protection if you
sit too close to the steering wheel or dash­

board.
There is also a risk of injury if the air-
bags are inflated. The front seats and head
restraints must always be positioned cor­
rectly for the height of the occupant.
- If you do not wear a seat belt, if you lean
forward or to the side, or are not seated cor­
rectly while the vehicle is in motion, you are
at greater risk of injury. Should the airbag
system be triggered in an accident there is
an even greater risk of injury.
- Never let a child travel on the front seat
without an appropriate restraint system. If
the airbag is triggered in an accident, the
child could sustain serious or fatal injuries

^>page
267, Child seats.
- Child seats in which the child faces the rear
of the car are located directly in the path of
the front passenger's airbag if it inflates. In
this case, the child could sustain serious or
fatal injuries if the airbag were to be de­

ployed.

- Applies to vehicles on which the front pas­
senger's airbag cannot be deactivated: Do
NOT use a rearward-facing child seat on
the front passenger's seat.
- Applies to vehicles with key-operated
switch for deactivating the front passeng­
er's airbag: Do NOT use a rearward-facing
child seat on the front passenger's seat
while the front passenger's airbag is ac­

tive.
If you have no alternative but to use a
rearward-facing child seat on the front
passenger's seat, the front passenger's
airbag must be deactivated beforehand via
the key-operated switch*
^>page
288.
Make sure that the front passenger's air-
bag is reactivated by means of the key-op­
erated switch* as soon as the child seat is
no longer needed on the front passenger's
seat.
- Occupants sitting in the front of the car
must never carry any objects or pets in the
space between them and the airbags, or al­
low children or other passengers to travel in
this position.
- Do not cover or stick anything on the steer­
ing wheel hub or the soft plastic surface of
the airbag unit on the passenger's side of
the dashboard, and do not obstruct or modi­
fy them in any way. These parts should only
be cleaned with a dry cloth (or with a cloth
moistened with plain water). It is also im­
portant not to attach any objects such as
cup holders or telephone mountings to the
surfaces covering the airbag units.
- Any work on the airbag system or removal
and installation of the airbag components
for other repairs (such as repairs to the
steering wheel or removal of seats) must be
performed by a qualified workshop.

Side airbags
Description of side airbags

The
airbag system is not a substitute for the seat
belts.

Fig.
232 Side airbags: Location in driver's seat (example)
The side airbags are located in the backrest
pad­

ding of the front seats.
In conjunction with the three-point seat belts,
the side airbags give the occupants additional
protection for the whole upper part of the body

(i.e.
the chest, stomach and pelvis) in the event
of
a
severe side collision
•=> A
in Important safety
notes on the side airbag system on page 285.
In a side collision the side airbags reduce the risk
of injury to the areas of the body facing the im­
pact.
How the side airbags work
When fully inflated, the side airbags reduce the
risk of injuries to the upper part of the
body.

Fig.
233 Side airbags in inflated condition
In certain types of side collision, the side airbag
(front) is triggered on the impact side of the
vehi­

cle
^Fig.
233. Further airbag systems may also
be triggered, depending on the circumstances.
When the system is triggered, the airbag is filled
with propellant gas.
In order to provide the desired extra protection in
an accident, the airbags have to inflate extremely
rapidly (within fractions of
a
second).
The fully deployed airbags cushion the impact for
the occupants and help to reduce the risk of in­
jury to the upper part of the body on the side fac­
ing the door.
Important safety notes on the side airbag
system

There
are a number of safety points concerning
the airbag system which you should remember.
This will help to reduce the risk of injury in an ac­
cident.
WARNING
-If
you
do
not
wear
a
seat belt, if
you
Lean

forward,
or are not seated correctly while
the vehicle is in motion, you are at greater
risk of injury should the side airbags be
trig­

gered in an accident. This applies particular­
ly to children if they are not properly protec­
ted by
a
child restraint system.
- If children are not seated correctly, they are
at greater risk of injury should the airbag
system be triggered in an accident. This is
particularly the case if the child is travelling
on the front passenger's seat and the airbag
system is triggered in an accident. This
could result in serious or potentially fatal in­
jury
^>page
267, Child seats.
- It is important not to attach any accessories
(such as cup holders) to the doors. This
would impair the protection offered by the
front side airbags.
- The sensors for the airbags are located in
the front doors. You must therefore not
make any modifications to the doors or door
trim (e.g. retrofitting loudspeakers),
as
this
could impair the function of the side air-

bags.
Any damage to the front doors could
285

Airbag system
lead to faults in the system. Repairs or any
other work on the front doors must there­
fore always be carried out by
a
qualified
workshop.
- The built-in coat hooks* should only be used
for lightweight clothing. Do not leave any
heavy or sharp-edged objects in the pockets.
- Do not apply excessive force to the sides of
the backrests (such as hard knocks or kicks),
as this could damage parts of the system.
The side airbags could then fail to operate
when required.
- If
you
intend to fit protective covers over
the seats, these must be of the specific type
approved for use on Audi seats with side air-

bags.
Conventional seat covers would ob­
struct the side airbag when it inflates out of
the backrest, and seriously reduce the air-
bag's effectiveness.
- Any damage to the original seat upholstery
or around the seams of the side airbag units
must be repaired immediately by a qualified
workshop.
- Any work involving the side airbag system or
removal and installation of the airbag com­
ponents for other repairs (such as repairs to
the seats) must always be performed by a
qualified workshop. Otherwise the airbag
system may fail to work properly.
© Note
All the other airbags in the car will remain
functional if the front passenger's airbag has
been deactivated.
Head-protection airbags
Description of head-protection airbags



Fig.
234 Location of head-protection airbags above the
doors (example)
The head-protection airbags are located above
the doors on the left and right sides of the
vehi­

cle.
The locations of the airbags are marked with
the word "AIRBAG".
In conjunction with the three-point seat belts
and side airbags, the head-protection airbags
give the occupants additional protection against
head and neck injuries in a severe side collision

•=>
A in Important safety notes on the head-pro­
tection airbags on page 287.
Together with other design features (including
cross-braces in the seats and the overall strength
of the body structure), the head-protection and
side airbag system offers an effective further im­
provement to occupant protection in side im­

pacts.

How the head-protection airbags work
When fully inflated, the airbags reduce the risk
of head or chest injury in a side collision.

Checking and topping up fluids
- Never remove the engine cover panel - risk
of burns!
- If any tests have to be performed with the
engine running, there is an extra safety risk
from the rotating parts, such as the drive

belts,
alternator and radiator
fan,
etc., and
from the high-voltage ignition system.
- Never touch the radiator fan. The electric
additional fan is controlled by temperature
and can start running without warning.
- Applies to vehicles with automatic gearbox:
Never open the throttle inadvertently (for
instance by hand from the engine compart­
ment) if
a
gear is engaged while the vehicle
is stationary with the engine running. The
vehicle will otherwise start moving immedi­
ately and could cause an accident.
- Observe the following additional warnings if
work on the fuel system or the electrical
system is necessary:
- Do not smoke.
- Never work near naked flames.
- Always keep an approved fire extinguisher
immediately available.
- Any work on the batteries and electrical sys­
tem in your vehicle entails a risk of injury
and chemical burns in addition to danger of
accident or fire.
For
this reason, you must
have the work carried out by
a
qualified
workshop.
© CAUTION
When topping up fluids make sure the correct
fluid is put into the correct filler opening. This
can otherwise cause serious malfunctions or
engine damage.
® For the sake of the environment
Inspect the ground underneath your vehicle
regularly so that any Leaks are detected at an
early stage. If
you
find spots of oil or other

fluids,
have your vehicle inspected in the
workshop.

Care of vehicle and cleaning
- Never clean the camera lens with cleaning
agents which are abrasive or contain alco­
hol - danger of scratches and cracks ap­

pearing.

- Windows and windscreen
- Remove snow and ice from windows and
exterior mirrors with a plastic scraper on­
ly. To avoid scratches, the scraper should
only be pushed in one direction and not
moved to and fro.
- Never use warm or hot water to remove
snow and ice from windows and mirrors.
This could cause the glass to crack!
-To avoid damaging the heating element,
do not put stickers on the inner side of the
rear window.
- Ornamental trim/mouldings
- Do not use chrome cleaning agents.
- Paintwork
- The vehicle must be free of dirt and dust
before applying polish/wax - otherwise
the paintwork may be damaged.
- Do not polish/wax the vehicle in direct
sunLight - this can damage the paint!
- Do not attempt to polish out surface rust
deposits - this can damage the paint!
- Remove cosmetics and sun Lotion immedi­
ately - otherwise the paintwork may be

damaged.

- Displays/instrument cluster
-The displays/instrument cluster and the
surrounding trim must not be cleaned
with a dry cloth - this can scratch the sur­

faces!

- Before cleaning, ensure that the instru­
ment cluster is switched off and
cool.

- Do not let any Liquid get between the in­
strument cluster and the trim - risk of
damage!
- Do not exert heavy pressure on the head-
up display* when cleaning it. This could
push the dispLay out of its guide rails - risk
of damage!
- Control consoles
- Do not let any liquid get inside the control
consoles - risk of damage!
- Seat belts
- Do not remove the seat belts to clean

them.

- Do not use chemical cleaning agents, cor­
rosive liquids, solvents or sharp instru­
ments to clean the seat belts or their com­
ponents - this can damage the belt web­

bing!

- If
you
find any damage to the belt web­

bing,
the belt fittings, the belt retractor or
the buckle, have the belt in question re­
placed by
a
qualified workshop.
- Fabrics/leatherette/Alcantara
- Do not use leather care products,
sol­

vents,
wax polish, shoe cream, stain
re­

movers, or any similar products on leath­
erette/Alcantara fabrics.
-To avoid damage, stubborn stains should
be removed by
a
qualified workshop.
- Never use steam cleaners, brushes, hard
sponges or similar utensils.
- Do not use the seat heating* to dry the

seats.

- Sharp-edged objects on clothing, such as
zip fasteners, rivets or belts, can also
damage the surface of the fabric.
- Please make sure you close any velcro fas­
teners, e.g. on your clothing, as these
could otherwise damage the upholstery.
- Natural leather
- Do not use solvents, wax polish, shoe

cream,
stain removers, or any similar
products on leather fabrics.
- Sharp-edged objects on clothing, such as
zip fasteners, rivets or belts, can also
damage the surface of the fabric.
- Never use steam cleaners, brushes, hard
sponges or similar utensils.
- Do not use the seat heating* to dry the

seats.

- Avoid exposing leather to direct sunlight
for long periods, otherwise it may tend to
lose some of its colour. If the car is
Left
for
a prolonged period in the bright sun, it is

best
to cover the leather. •
