[ i] Tips
Many functions are monitored by the Auto-Check system
~ page 28. Malfunctions or faults will be identified either with a red
symbol (priority 1 -Danger!) or with a yellow symbol (priority 2 -
Warning) .•
Malfunction Indicator Lamp (MIL)
L.i (USA models)/ (Canada models)
The Malfunction Indicator Lamp (MIU is part of the On-Board Diag­
nos tic (OBD Ill system. The symbol,.. lights up when the ignition is
turned on and will turn off after the engine has started and has
settled at constant idle speed . This indicates that the MIL is wo rking
properly.
The warning light illuminates when there is a malfunction in the
engine electronic syst em . Contact your authori zed Audi d ealer and
have the malfunction corrected.

Instruments and warning/indicator lights
Airbag system ~
This warning/indicator light monitors the airbag and the
tensioner systems.
The GA warning light illuminates for a few seconds each time you
switch on the ignition.
If the
ffl warning light does not go out, or if it illuminates while you
are driving, or if it starts to flash, then there is a malfunction some ­
where in the system. If the light does not illuminate when you
switch on the ignition, this also means there is a malfunction.
& WARNING
If you have a malfunction in the airbag system, contact your autho­
rized Audi dealer immediately. Otherwise the airbag or the belt
tensioner may not work properly in an accident. •
Tire pressure monitoring system -telltale
indicator lamp
D
The warning/indicator light appears in the event of a
significant loss of air pressure.
The warning/indicator light illuminates for a few seconds after
the ignition is turned on as function check and then goes out.
If the ( symbol appears, pressure is too low in at least one tire.
When the system detects a malfunction, the warning/indicator light
will flash for approximately one minute and then remain continu­
ously illuminated. This sequence will continue upon subsequent
vehicle starts up as long as the malfunction exists. Contact your
authorized Audi dealer and have the malfunction corrected.

There is a malfunction in the ABS when:
• the warning/indicator light does not illuminate when you switch
on the ignition.
• the warning/indicator light does not go out after a few seconds.
• the warning/indicator light illuminates while driving.
Without the electronic assistance of the ABS, the brake system will
still respond and brake the car. Have the brake system checked and
restored to its full performance by an authorized Audi dealer as
soon as possible.
For more information regarding the ABS see
=> page 216.
Since any malfunction of the ABS also affects the ESP, that system's
warning symbol.,
=> page 22 will light up along with the n /
(Canada models) warning light.
Unspecific malfunction in the brake system
If both the brake warning light=> page 23 and the c.., warning light
illuminate when the parking brake is released, the likely cause is a
serious malfunction in the brake system beyond an inoperative ABS
=> & . ~

If an unspecific defect in the brake system is indicated, the entire
b rake system is likely to be a ffec ted a nd y ou mus t ex pec t degra ded
brake response and performance .
Since any malfunction of the ABS also effects the ESP, that system's
w arning symbol

• it illuminates when there is a ma lfunction in the ESP.
• it illuminates after the battery has been disconnected.
• it illuminates continuous ly when the ESP is switched off.
• it illuminates if there is a malfunction in the ABS, since the ESP
is part of the ABS system.
If the ESP warning/indicator light i lluminates and stays on after you
have started the engine , this may mean that the control system has
temporari ly switched off the ESP. If this is case, you can reactivate
the ESP by switching the ignition o ff and then on again. The
warning/indicator light should go out to show that the system is
fully functional again.
If the battery terminals were disconnected and re-connected, the
vehic le was jump started or the battery is very weak, the ESP sensor
system goes through a learning process for the first few yards.
During this time, the indicator light illuminates. It goes out as soon
as the learning process is comp lete .

and an accident. Have your vehicle repaired immediately by your
authorized Audi dealer or a qualified workshop. Drive slowly and
avoid sudden, hard brake applications.
• Canada models: If the brake warning light (CD) and the ABS
warning light _. come on together, the rear wheels could lock up
first under hard braking. Rear wheel lock-up can cause loss of
vehicle control and an accident. Have your vehicle repaired imme­
diately by your authorized Audi dealer or a qualified workshop.
Drive slowly and avoid sudden, hard brake applications.
• If the brake warning/indicator light does not go out after a few
seconds and the parking brake released, or lights up while you are
driving, the fluid level in the brake fluid reservoir is too low. If you
believe that it is safe to do so, proceed immediately at low speed
to the nearest authorized Audi dealer or qualified repair facility
and have the brake system inspected .
• Always keep in mind that after several brake applications, you
will need greater pressure on the brake pedal to stop your vehicle.
Do not rely on strained brakes to respond with maximum stopping
power in critical situations . You must allow for increased braking
distances. The extra distance used up by fading brakes could lead
to an accident. •
