WARNING
Tips
Many functions are monitored by the Auto Check system. Malfunctions or faults will be identified either with a red symbol (priority 1 - Danger!) or with a yellow symbol (priority 2 - Warning).
EPC Electronic power control
Applies to vehicles: with gasoline engine
This warning/indicator light monitors the electronic power control.
The warning/indicator light
(Electronic Power
Control) illuminates when you turn on the ignition
as a function check.
Tips
If this warning/indicator light illuminates while you are driving, then there is a malfunction in the engine electronics. Have the malfunction corrected as soon as possible by your authorized Audi dealer or qualified workshop.
Glow plug system
Applies to vehicles: with diesel engine
The control light illuminates when the glow plug system is active.
If the indicator light
illuminates, the glow
plug system is active. You should start the engine
immediately after the indicator light switches off.
The indicator light only illuminates for approximately
1 second if the engine is warm or if the
outside temperature is above 46 F (8
C).
Tips
The engine should be checked.
Electronic Stabilization
Control (ESC)
If the indicator light blinks
while driving, the
ESC or ASR (Anti-Slip Regulation) is actively regulating.
If the indicator light turns on,
the system has
switched the ESC off. In this case, you can switch
the ignition off and then on to switch the ESC on
again. The indicator light turns off when the system
is functioning fully.
If the indicator light turns on,
ESC was restricted
using the
button.
Stabilization control (ESC/ABS): Fault! See owner's manual
If the indicator light and the
ABS indicator
light
(USA models)
( Canada models)
turn on and the message appears, the ABS or
electronic differential lock is malfunctioning. This
also causes the ESC to malfunction. The brakes still function with their normal
power, but ABS is not active.
Drive to your authorized Audi dealer or qualified workshop immediately to have the malfunction corrected.
WARNING
If the (USA models)
(Canada models)
brake system indicator light turns on together
with the ABS and ESC indicator lights,
the ABS/ESC regulating function may have
failed. Functions that stabilize the vehicle are
no longer available. This could cause the vehicle
to swerve and increase the risk of sliding.
Drive carefully to the nearest authorized Audi dealer or other qualified workshop and have t he malfunction corrected.
Tips
For additional information on ESC and ABS.
Safety systems
The (USA models) /
(Canada models) indicator light
monitors the safety systems (e.g. airbags, pretensioners) and illuminates for a
few seconds each time you switch the ignition on.
If the (USA models) /
(Canada models) indicator light
does not go out, or if it illuminates while you are driving, or if it starts to
blink, then there is a malfunction somewhere in the system.
If the light does not illuminate when you switch the ignition on, this also
means there is a malfunction.
WARNING
If you have a malfunction in the safety systems, contact your authorized Audi dealer immediately. Otherwise the safety systems may not work properly in an accident.
Tire pressure monitoring
system - telltale indicator lamp
Applies to vehicles: with tire pressure monitoring system
The warning/indicator light appears in the event of a significant loss of tire pressure or if there is a malfunction.
The indicator light illuminates
to check the function when you switch on the ignition.
If the symbol remains on or blinks
after you switch on the ignition, there is a loss of tire pressure or a system
malfunction. If there is a system malfunction, see your authorized Audi dealer
as soon as possible.
Detailed information on the tire pressure monitoring system can be found.
Turn signals
The indicator tight blinks when you use either turn signal.
Whenever you use the left the
right
turn signal, the indicator
light blinks. When you use the emergency flashers, both indicator lights flash.
If one of the turn signal light bulbs burn out, the turn signal will blink twice as fast as normal.
This does not apply, however, in towing mode. The indicator light does not flash if a turn signal is out on the trailer or the towing vehicle. Additional information on the turn signals.
Trailer turn signal assembly
Applies to vehicles: with towing hitch
The indicator light also blinks if the turn signal is operated when towing a trailer.
The indicator light blinks when
the turn signal is used, if a trailer has been properly connect ed to the
vehicle.
If one of the turn signal bulbs on the trailer is burned out or defective, the indicator light will not blink when you use the turn signals.
Tips
For vehicles with a factory installed towing hitch or a trailer hitch that was installed later according to factory specifications, the trailer turn signal assembly is actuated.
Safety belts
This warning/indicator light reminds you to put on your safety belt.
The warning/indicator light
illuminates when the ignition is switched on to remind the driver and (on USA
models only) any front passenger to put on the safety belt. Additionally, an
audible warning tone will also sound.
Malfunction Indicator Lamp
(MIL)
The Malfunction Indicator Lamp (MIL) is part of the On-Board Diagnostic (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 a constant idle speed. This indicates that the MIL is working
properly.
The warning light illuminates when there is a malfunction in the engine electronic system. Contact your authorized Audi dealer and have the malfunction corrected.
An improperly closed fuel filler cap may also cause the MIL light to illuminate (only vehicles with gasoline engine).
High beam
The warning/indicator light
illuminates when the high beams are on or when you use the headlight flasher.
For more information about using the high beams.
Cruise control
The (USA models) /
(Canada models) warning/indicator
light illuminates when the cruise control is activated.
Anti-lock brake system (ABS)
This warning/indicator light monitors the ABS and the electronic differential lock (EDL).
The (USA models) /
(Canada models) warning/indicator
light will come on for a few seconds when the ignition is switched on. The light
will go out after an automatic check sequence is completed.
There is a malfunction in the ABS when:
The brake system will still respond even without the assistance of the ABS system. See your authorized Audi dealer as soon as possible to restore full braking performance. For more information regarding the ABS.
The ABS warning light and the brake warning light come on together. The ABS will not work and you will notice a change in braking response and performance.
Malfunction in the brake system
If the brake warning light and the ABS warning illuminate together there may be a malfunction in the ABS, and there may also be a malfunction in the brake system itself.
In the event of a malfunction in the brake system the warning/indicator light
(USA models)/
(Canada models) in the instrument
cluster flashes. By pressing the [SET] button, you can bring up a driver message
which explains the malfunction in more detail.
Malfunction in the electronic differential lock (EDL)
The EDL works together with the ABS. The ABS warning light will come on if there is a malfunction in the EDL system. See your authorized Audi dealer as soon as possible.
WARNING
Electromechanical parking
brake
The warning/indicator light monitors the electromechanical parking brake.
With the parking brake applied and the ignition turned on, the
(USA models)

light illuminates.
After the ignition has been turned off, the warning/indicator light continues to illuminate for about 30 seconds. If the parking brake is applied with the ignition turned off, the warning/indicator light illuminates for about 30 seconds.
The warning/indicator light will go out when the parking brake is released.
If the warning/indicator light flashes continuously after applying the parking brake, braking force is not sufficient to prevent the vehicle from rolling unintentionally. Please note the following:
Brake system
The warning/indicator light flashes if brake fluid level is low, if there is an ABS system malfunction or a parking brake malfunction.
The (USA models)
(Canada models) light illuminates
when the ignition is turned on.
It goes out after the engine has been started. This indicates that the brake warning light is functioning properly.
If the brake warning light does not light up when the engine is cranking, there may be a malfunction in the electrical system. In this case, contact an authorized Audi dealer.
