[ 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)
~ (USA models)/ 0 (Canada models)
The Malfunction Indicator Lamp (MIU is part of the On-Board Diag ­
nostic (OBD II) 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 working
properly.
The warning light illuminates when there is a malfunction in the
eng ine electronic system. Contact your authorized Audi dealer and
have the malfunction corrected.
For more information
=> page 27. •
Airbag system ~
This warning/indicator light monitors the airbag and the
tensioner systems.
The I warning light illuminates for a few seconds each time you
switch on the ignition.
If the
~i warning light does not go out, or if it illum inates 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
U)
The warning/indicator light appears in the event of a
significant loss of air pressure.
The (1) warning/indicator light illuminates for a few seconds after
the ignition is turned on as function check and then goes out.
If the
(l) 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 ill uminate when you switch
o n t he ign ition .
• the warning/indicator light does not go out after a few seconds .
• the warning/i ndicator light illu minates 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.

Aud i deale r as s oon as poss ible.
& WARNING
• If the ABS/ 8 (Canada models) warning light does not go out ,
or if it comes on while driving, the ABS system is not working
properly . The vehicle can then be stopped only with the brakes
operating without ABS support . You will not have the protection
ABS provides. Contact your Audi dealer as soon as possible.
• USA models : If both the BRAKE warning light and the ABS
warning light come on at the same time, the rear wheels could lock up first under hard braking. Rear wheel brake lock-up can
cause loss of vehicle control and an accident . Have your vehicle
repaired immediately by your authorized Audi dealer or a qualified
workshop. Drive slowly and avoid sudden , hard brake application .
• Canada models : If both the brake warning light ((DJ and the ABS
warning light
0 come on at the same time , the rear wheels could
lock up first under hard braking. Rear wheel brake lock-up can
cause loss of vehicle control and an accident . Have your vehicle
repaired immediately by your authorized Audi dealer or a qualified
workshop. Drive slowly and avoid sudden, hard brake
application. •

Safety belts i
This warning/indicator light reminds y ou to put on your
safety belt.
The .ft warning/indicator light i lluminates when the ignition is
switched on to remind the driver and (on USA mode ls only) any front
passenger to put on the safety belt. Additiona lly, an acoustic

The in dicator light flashes when you use either turn
signal.
Whenever you use the left ¢ or the right ¢ turn signal, the indicator
l ight flashes. W hen you use the emerge ncy flasher, both indicator
lights f lash .
I f one of the turn signal light bulbs burn out, the turn signal will
flash twice as fast as normal. •
Electronic Stabilization Program (ESP) fJ
The warning/indicator ligh t monit ors the electr onic s tabi ­
lization program.
The ~ warning/indicator light has the fol lowing functions:
• it flashes while you are driving, when the ESP is working .
• it illuminates when you switch on the ignition for approximately
2 seconds as a funct ion check.
• 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 o f the ABS system.
If the ESP warning/indicator light illuminates and stays on after you
have started the engine, this may mean that the control system has
temporar ily switched o ff the ESP . If this is case, you can reactivate
the ESP by switching the ignition off and then on again . The
warning/indicator light should go out to show that the system is
ful ly functional again .
I f 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 p rocess for the firs t few yards.
D uring th is time, t he ind icator l ight i llu minates. It goes out as soo n
as the learning process is comp lete.
