Note
•
The needles in the instrument cluster will sweep across the dials
when you switch on the ignition.
•
The instrument lighting (illumination of dials and needles) is
switched on when the ignition is on and the vehicle's lights are off.
The instrument lighting is dimmed automatically as the daylight
starts to fade. This function is intended to remind the driver to
switch on the dipped-beam headlights in good time when light
conditions become poor.
Coolant temperature gaugeThe coolant temperature gauge ⇒fig. 2 only works when the
ignition is switched on. In order to avoid possible damage to the
engine, please read the following notes for the different tempera-
ture ranges.
Engine cold
If the needle is still in the lower range of the dial, this indicates that
the engine has not yet reached operating temperature. Avoid high
engine speeds, full acceleration and heavy engine loads.
Normal temperature
In normal operation the needle will settle somewhere in the centre
of the dial once the engine has reached operating temperature. The
needle may also go further up when the engine is working hard at
high outside temperatures. This is no cause for concern provided
the warning symbol
 in the display does not start flashing.

Instruments and warning/indicator lamps
16Additional warning and indicator lamps are displayed on vehicles
equipped with the adap tive cruise control* ⇒page 134 .
Note
A number of functions are monitored by the auto-check control
⇒page 21 . If a malfunction should occur, this will be shown by the
display in the instrument cluster either with a red symbol (priority 1
– serious malfunction) or a yellow symbol (priority 2 – other
malfunction or item requiring attention).Applies to vehicles: with Audi drive selectDynamic steering

If the warning lamp
 lights up when you switch on the ignition and
goes out when the engine has starte d, the dynamic steering is acti-
vated.
If the warning lamp  stays on after the engine has started, this
indicates a malfunction in the system. You can continue driving
carefully at reduced speed to the next qualified workshop, however
the steering may feel heavier and its response may be more sensi-
tive than usual. In addi tion, it is possible that the steering wheel will
be off centre when driving in a straight line.
WARNING
Have the system malfunction in the dynamic steering repaired by
a qualified workshop as soon as possible – risk of accident.
Note
•
If the warning lamp
 flashes, this indicates that the dynamic
steering is being initialised. The message “Dynamic steering: Initial-
ising” ⇒page 36 will appear in the driver information system
display.
•
The stabilisation functions of the dynamic steering ⇒page 222
are not available in the event of a system malfunction.
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.Note
If 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 glow plugs are preheating.
If the engine fails to start imm ediately, 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 tracti on 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 222 .
•
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 should 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 initialisation 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 an d 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 222 .
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 th is is neglected, there is a risk
that the airbag system and/or belt tensioners may not be acti-
vated in an accident.Tyre pressure monitoring

The tyre pressure should be corrected as soon as possible
if it is too low.If the
 symbol flashes for about a minute and then remains lit after
you switch on the ignition, there is a fault in the system. Please
contact the nearest qualified workshop as soon as possible.
For more detailed information on the tyre pressure monitoring
system, please refer to ⇒page 39 .
