A WARNING
"---
- If the E (USA mode ls)l ii] (Canada
models) warning light does not go out,
or if it comes on whi le driving, the ABS
system is not work ing properly . The vehi­
cle can then be stopped only with the
standard brakes (without ABS). You w ill
not have the protection ABS provides.
Contact your Audi dea ler as soon as pos­
sible.
- USA models: If the 1111 warning ligh t,
the
J;.J warning light and the & warn­
ing light come on together, the rear
wheels could lock up first under hard
brak ing. Rear wheel lock-up can cause
loss of vehicle control and an accident.
Have your vehicle repaired immediately
by your authorized Audi dealer or a quali­
fied workshop. Dr ive slow ly and avoid
sudden, hard brake applications.
- Canada models: If the brake warning
light ., the
DJ warning light and the
ABS warning light
[( Gi a come on together,
the rear wheels could lock up first under
hard braking. Rear wheel lock-up can
cause loss of vehicle contro l and an acci­
dent . Have your vehicle repaired immedi­
ately by your authorized Audi dealer or a
qualified workshop. Drive s lowly and
avoid sudden, hard brake applications.
{0) Worn brake pads
EtJ Check brake pads!
If the warning light i lluminates, immediate ly
contact your authori zed Audi dealer or quali­
fied workshop to have all brake pads inspect­
ed . On USA models the warn ing light
EtJ
comes on together with the warning light
1111. Both sets of brake pads on an ax le
must always be replaced at the same time.

(D Note
The instrument cluster and center console
illumination (gauges and needles) comes
on when you switch on the ignition and the
vehicle headlights are off. Be aware of the
following difference between models built
to US or Canadian specifications :
- USA models: illumination of the instru­
ment cluster (gauges and needles), dash
and center console around the gearshift
lever is controlled by a light sensor locat­
ed in the instrument panel. The instru­
ment panel illumination will automati­
cally become dimmer as the daylight
fades away and eventually will go out
completely when outside light is very low.
This is to remind you, the driver, to
switch on the headlights before it gets
too dark.
- Canada models: instrument panel illumi­
nation will stay brig ht regardless of the
intensity of ambient light. Always be
aware of changes in outside light condi­
tions while you are driving. Respond in
time to fading daylight by turning the
light switch to position fD (or "AUTO" if
your car is equipped with this feature) to
turn on your headlights.
Luggage compartment light

122 Airbag system
Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different places on your Audi. Installing,
removing, 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 system will not be impaired and that dis­
carded components do not cause injury or pol­ lute the environment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an airbag from deploying when needed or deploying
an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel horn pad or airbag cover
or the instrument panel or modify them
in any way.
- Never attach any objects such as cup
holders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened 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 de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system.
- All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including 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
authorized Audi dealer or qualified work­
shop. -
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 replace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags inflate.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can be activated only
once. After an airbag has inflated, it
must be replaced by an authorized Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only
once. After an airbag has been deployed,
it must be replaced with new replace­
ment parts designed and approved espe­
cially for your Audi model version. Re­
placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only.
Make sure that any airbag service action
is entered in your Audi Warranty & Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD.
- For safety reasons in severe accidents,
the alternator and starter are separated
from the vehicle battery with a pyrotech­ nic circuit interrupter.
- Work on the pyrotechnic circuit inter­
rupter must only be performed by a
qualified dealer -risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.

@ For the sake of the environment
Undeployed airbag modules and preten­
sioners might be classified as Perchlorate
Material -special handling may apply, see
www.dtsc.ca .gov/hazardouswaste/per­
chlorate. When the vehicle or parts of the
restraint system including airbag modules
and safety belts with pretensioners are
scrapped, all applicable laws and regula­
tions must be observed. Your authorized
Audi dealer is familiar with these require­
ments and we recommend 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 Sys­
tem 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, suspen­
sion 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 exam­
ple, increase the force levels measured 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 meas ­
ured by the sensors and prevent the airbag
from deploying when it should.
The sensors in the safety belt buckle for the
driver and front passenger seat tell the elec­
tronic control module if the safety belt is
latched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high­
er rate of vehicle deceleration than if the safe­
ty belt is not being used. Therefore, in a par­
ticular collision, it is possible that an airbag
will not deploy at a seating position where the safety belt is being used but will inflate at the
position where the safety belt is not being
used. It is important that nothing interfere
with the safety belt buckles so that the sen-
Airbag system 123
sors can send the correct information about
safety belt use to the electronic control unit.
A WARNING
Changing the vehicle's suspension includ­
ing use of unapproved tire-rim combina­
tions can change Advanced Airbag per­
formance and increase the risk of serious personal injury in a crash.
- Never install suspension components
that do not have the same performance characteristics as the components origi­
nally installed on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.
A WARNING
-
Items stored between the safety belt
buckle and the center console can cause
the sensors in the buckle to send the
wrong information to the electronic con­
trol module and prevent the Advanced Air­
bag System from working properly.
- Always make sure that nothing can inter­ fere with the safety belt buckles and that
they are not obstructed.

Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers fo r the express purpose of capturing
data for retrieval after an accident or crash
event . EDR's are sometimes ca lled "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
A lthough your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, eng ine function, em is­
sion control, as well as for the airbags and
safety belts.
These electronic contro l modules also record
vehicle-re lated data during normal vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited pe riod of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only
be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of vehicle control. It works
only when the engine is running. ESC detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering assistance to help hold the
vehicle on the driver's intended course. The in­
dicator light
G) in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
physics. It wi ll not always be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of
dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it wou ld on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered.
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations as at lower
speeds.
Always adjust your speed and driving style to
road , traffi<;: and weather conditions. ESC can­
not override the vehicle's physical limits, in­
crease the available tract ion, or keep a vehicle
on the road if road departure is a result of
driver inattention . Instead, ESC improves the
poss ibility of keeping the vehicle under con­
t rol and on the road during extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle going in the intended di­
rection . If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC includes and/or works together with the
anti- lock brake system (ABS), brake assist sys-
tem and anti-slip regu lation (ASR). ESC is .,..

switched on all the time. In certain situations
when you need less traction, you can switch
off ESC by pressing the button
lru . Be sure to
switch ESC on again when you no longer need
less traction.
Anti -loc k brak ing s ystem (ABS )
ABS prevents the wheels from locking up
when braking . The vehicle can still be steered
even during hard braking. Apply steady pres­
sure to the brake pedal. Do not pump the ped­
al. A puls ing in the brake pedal indicates that
the system is helping you to brake the vehicle.
B rake ass is t system
The brake assist system can decrease braking
d istance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency situations. You must press and hold the
brake pedal until the situation is over .
Anti-slip regulati on (ASR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it easier to
start, accelerate and drive up hills.
Elect ronic diff erential lock (EDL )
The EDL brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h).
In extreme cases, EDL automat ica lly switches
off to help keep the brake on the braked wheel
from overheating. EDL w ill switch on again au­
tomatically when conditions have returned to normal.
..&, WARNING
- ESC, ABS, ASR and EDL cannot ove rcome
t he laws of physics. This is espec ia lly im ­
portant on slippery or wet roads.
If the
systems begin act ing to stab ilize your ve­
hicle, you should immediately change
yo ur speed to match the road and traffic
condit ions. Do not let the increased safe­
ty provided by these systems tempt you
Intelligen t technolog y 151
to take risks. Doing so will increase the
risk of a loss of vehicle control, co llision
and serious personal injuries.
- Always adapt your speed to road, traffic
and weather conditions. The risk of los­
ing control of the vehicle increases when
driving too fast, espec ially through
curves and on slippery or wet roads, and
when driving too close to vehicles up ahead. ESC, ABS, the brake assist sys­
tem, EDL and ASR cannot preven t coll i­
sions.
- Always ac celera te with spe cial care on
even, smooth s urfaces su ch as those th at
are wet or covered with ice and snow.
The drive wheels can spin even with these assistance systems that cannot al ­
ways he lp to reduce the risk of loss of ve­
hicle control.
@ Tips
- ABS and ASR only work correct ly when
all four whee ls are equipped with identi­
cal tires. D ifferent tire sizes can lead to a
reduction in engine power.
- You may hear noises when the systems described are working.
-If the ind icator lightD] orE (USA
models)/ [iJ (Canada models) appears,
there may be a malfunction¢ page 18,
