Warning and indicator lampsOverview
The warning and indicator lamps indicate a number of
different functions and possible faults.Fig. 7 Instrument cluster with warning and indicator lamps
Note
A number of functions are monitored by the auto-check control
⇒page 20 . If a malfunction should occur, this will be shown by the
display in the instrument cluster eith er with a red symbol (priority 1
– serious malfunction) or a yellow symbol (priority 2 – other
malfunction or item requiring attention).Applies to vehicles: with petrol engineEngine management

This warning lamp monitors the engine management
system on petrol engines.The
 warning lamp (Electronic Power Control) lights up when the
ignition is switched on to show that the lamp is working properly.

Instruments and warning/indicator lamps
16
NoteIf the warning lamp lights up while the vehicle is moving, this indi-
cates a fault in the engine management system. The engine should
be serviced by a qualified workshop without delay.Applies to vehicles: with diesel engineGlow plug system

The indicator lamp lights up to show that the glow plugs
are preheating.Your vehicle is equipped with an automatic glow plug system.
The indicator lamp
 lights up while the gl ow plugs are preheating.
If the engine fails to start imme diately, the glow plugs have not
finished preheating. In this case, keep the clutch pedal depressed
(or keep your foot on the brake if your vehicle has an automatic
gearbox) until the engine starts.
Note
•
If the glow plug indicator lamp should start flashing while the
vehicle is moving, this indicates a fault in the engine management
system. The engine should be serviced without delay.
•
If the indicator lamp fails to light up when the ignition is
switched on, this can mean that the glow plug system is defective.
The engine should be serviced.
Electronic stabilisation program (ESP)

This warning lamp monitors the electronic stabilisation
program.The warning lamp
 has the following functions:
•
It flashes when the ESP or trac tion control system (ASR) inter-
venes while the vehicle is in motion.
•
The warning lamp will light up continuously if the ESP or the
traction control system (ASR) has been switched off using the ESP
OFF button ⇒page 196 .
•
It lights up when the ignition is switched on and should go out
again after about 2 seconds. This signals that the lamp is working
properly.
•
It will light up continuously if there is a malfunction in the ESP.
•
It will also come on if a fault sh ould occur in the ABS because the
ESP operates in conjunction with the ABS.
If the battery has been disconnected, if the battery voltage is very
low, or if the engine has been started from an outside power source,
the ESP system will perform an init ialisation of the various on-board
sensors while you drive the first few metres. The warning lamp will
light up during this period. It will go out when the initialisation has
been completed.
If the warning lamp lights up and stays on after the engine is
started, this may mean that the control system has temporarily
switched off the ESP. In this case the ESP can be reactivated by
switching the ignition off and then on again. If the warning lamp
goes out, this means the system is fully functional.
For further information on the ESP ⇒page 196 .
Airbag system

This warning lamp monitors the airbag and seat belt
tensioner system.The warning lamp
 should light up for a few seconds when the
ignition is switched on.
If the warning lamp does not go out, or if it lights up, flashes or
flickers when the vehicle is moving, this indicates a malfunction in
the system. This is also the case if the warning lamp does not light
up when the ignition is switched on.

WARNING
If a malfunction should occur, have the system checked immedi-
ately by a qualified workshop. If this is neglected, there is a risk
that the airbag system and/or belt tensioners may not be acti-
vated in an accident.Turn signals
 
Depending on which turn signal is operated, either the left
 or
right
 indicator lamp flashes. Both indicator lamps will flash when
the hazard warning lights are switched on.
If one turn signal should fail, the indicator lamp will start flashing
twice as fast.
This does not apply when towing a caravan or trailer. The indicator
lamp will stop flashing if one of th e turn signals on the vehicle or the
caravan/trailer should fail. For further information on the turn
signals ⇒page 59 .
Applies to vehicles: with towing bracketTrailer turn signals

The indicator lamp flashes when the turn signals are
operated while towing a caravan or trailer.The indicator lamp
 flashes when the turn signals are operated,
provided a caravan or trailer is correctly attached and connected to
the vehicle.
The indicator lamp will not flash if one of the turn signals on the
trailer fails.
Seat belt warning lamp

The warning lamp acts as a reminder to fasten the seat
belts.After switching on the ignition, the warning lamp
 will remain lit
until the driver and front passenger (if applicable) have fastened
their seat belts. When the vehicle has gathered speed you will also
hear a warning chime.
For further information on the seat belts ⇒page 170 .
Emission control system

If the warning lamp lights up continuously you should take your
vehicle to a qualified workshop as soon as possible in order to have
the fault rectified.
If the warning lamp flashes drive on at reduced speed and seek
professional help in order to avoid damage to the catalytic
converter.
For further information on the catalytic converter ⇒page 205 .Main beam headlights

The indicator lamp
 lights up when the main beams are on or
when the headlight flasher is operated.
For further information on the main beam headlights ⇒page 59 .
Applies to vehicles: with cruise control systemCruise control

The indicator lamp
 in the instrument cluster lights up when the
cruise control system is operating.

Technical data
Lock function can be switched on and off on the sound system or
MMI*
⇒page 44 .
In the event of an accident in which the airbags inflate, the doors
will be automatically unlocked to facilitate access and assistance.
Deadlock mechanism
The central locking system is combined with a deadlock mecha-
nism. Once the vehicle has been locked from the outside, the door
handles on the inside are deactivated. This makes it more difficult
to break into the vehicle.
Anti-theft alarm system*
If the anti-theft alarm system senses interference with the vehicle it
triggers an audible and visible alarm.
The anti-theft alarm system switches on automatically when the
vehicle is locked. It switches off automatically if you unlock the
vehicle using the remote control.
If you unlock the vehicle by inserting the key in the drivers door, the
ignition must be switched on within 15 seconds, otherwise the
alarm will be triggered. On some export versions, the alarm is trig-
gered immediately when you open a door.
To deactivate the alar m, press the unlock button on the remote
control key or switch on the ignition . The alarm will also switch itself
off when it comes to the end of its cycle.
Switch off the interior monitor an d tow-away protection if you wish
to prevent the alarm from be ing triggered accidentally.
Turn signals
The turn signals will flash twice when the vehicle is unlocked and
once when the vehicle is locked. If the turn signals do not flash, one
of the doors, the bonnet or the boot lid is still open.
Accidental lock-out
The central locking system prevents you from being locked out of
the vehicle in the following situations:
•
When the driver's door is open, it cannot be locked together with
the other door by pressing the central locking switch and then
closing the door ⇒page 47 .
•
On vehicles with advanced key*, the boot lid will be released
again automatically if the remote control key that was last in use is
left inside the boot when the boot lid is closed ⇒page 48 .
To prevent yourself from being locked out, do not lock the vehicle
with the remote control key before closing the doors or boot lid.
WARNING
Do not leave anyone (especially child ren) in the car if it is locked
from the outside and the deadlock mechanism is activated: the
doors and windows cannot then be opened from the inside.
Locked doors could delay assistance in an emergency, potentially
putting lives at risk.
Note
•
Never leave any valuable items in the vehicle unattended. Even a
locked vehicle is not a safe.
•
If the diode on the driver's window sill lights up for about 30
seconds when the vehicle is locked, the central locking system or
anti-theft alarm* is not working properly. Please have the malfunc-
tion repaired by an Audi dealer or qualified workshop.
•
The interior monitor of the anti-t heft alarm* system will only
function as intended if the windows and the tilting panorama roof*
are closed.
