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 glow plugs are preheating.
If the engine fails to start immediately, 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 traction 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 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 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.

Instruments and warning/indicator lamps 18Anti-lock brake system (ABS)

The warning lamp monitors the ABS and the electronic
differential lock (EDL).The warning lamp
 lights up for a few seconds when the ignition
is switched on and while the engine is being started. The lamp goes
out again once the system has run through an automatic test
sequence.
There is a fault in the ABS if:
•
the warning lamp
 does not light up when the ignition is
switched on,
•
the warning lamp does not go out again after a few seconds,
•
the warning lamp lights up when the vehicle is moving.
The vehicle can still be braked in the normal way (except that the
ABS control function is out of action). Please take the vehicle to a
qualified workshop as soon as possible. For further information on
the ABS ⇒page 197.
If a fault occurs in the ABS, the ESP warning lamp will also light up.
Fault in the main brake system
If the ABS warning lamp
 lights up together with the brake
warning lamp
 ⇒page 31, this indicates a fault in the ABS func-
tion, and possibly a malfunction in the main brake system as well
⇒.
If there is a malfunction in the brake system the symbol
 will light
up in the instrument cluster. Please refer to ⇒page 31.
Fault on the electronic differential lock (EDL)
The EDL works in conjunction with the ABS. If a malfunction should
occur in the EDL, this is indicated by the ABS warning lamp .
Please take the vehicle to a qualified workshop as soon as possible.
For further information on the EDL ⇒page 199.
WARNING
•
Before opening the bonnet and checking the brake fluid level,
observe the warning information on ⇒page 231, “Working on
components in the engine compartment”.
•
If the brake warning lamp
 should light up together with the
ABS warning lamp
, stop the vehicle immediately and check the
brake fluid level in the reservoir. If the fluid level has dropped
below the "MIN" mark you must not drive on - otherwise there may
be an increased accident risk. You should obtain professional
assistance.
•
If the brake fluid level is OK, the fault in the brake system may
have been caused by a failure of the ABS control function. As a
result the rear wheels can lock relatively easily when braking. This
could cause the tail of the vehicle to skid sideways. Drive carefully
to the nearest qualified workshop and have the fault rectified.
Applies to vehicles: with Audi hold assistAudi hold assist

This warning lamp monitors the Audi hold assist function.Audi hold assist helps the driver to keep the vehicle stationary while
the engine is running, for instance on steep gradients, at traffic
lights or in stop-and-go traffic. When the Audi hold assist function
is on, you don't have to keep your foot on the brake to prevent the
vehicle from accidentally rolling away. Once it detects that the
vehicle is stopped, Audi hold assist keeps the vehicle stationary. The
green symbol
 in the instrument cluster indicates that the func-
tion is activated. You can now take your foot off the brake pedal.
When the vehicle has been stationary for an extended period, Audi
hold assist will automatically apply the parking brake. In this case,
the green symbol  will change to red
.

Driver information system 20Driver information systemIntroductionGeneral notes
The driver information system in the instrument cluster
shows you the status of various on-board systems at a
glance.The display for the driver information system is in the centre of the
instrument cluster.
The system runs a check on certain components and functions
when the ignition is switched on and while the vehicle is moving. It
gives an audible warning if a fault should occur or if servicing is
required, and a red or yellow warning symbol (in some cases with a
corresponding driver message) appears in the dashboard display.
The system will also display information for the radio and CD player
and (if fitted) the route guidance directions from the navigation
system*. For further information on these systems, please refer to
the MMI operating manual.
On some models the display of information shown in the instru-
ment cluster differs from the illustrations used here.
The driver information system includes the following functions:
Note
If a fault should occur, the display will show a red or yellow warning
symbol. A red warning symbol indicates a serious malfunction
⇒page 30. A yellow warning symbol indicates a less serious
malfunction, or other item requiring attention ⇒page 34.

Driver information system 24
– The remaining time and distance to the next service are
indicated every time the ignition is switched on, until the
service becomes due.
Service due
–When a service is due, Service! will appear in the display
as soon as you switch on the ignition. The display reverts
back to the standard display after about 5 seconds.
Displaying the service interval
– Select: Function selector button > Service interval
display ⇒page 23, fig. 15.
Resetting the oil change interval display
– Select: Function selector button > Service interval
display > Reset oil change interval.Displaying distance to next service
You can have the distance to the next service displayed on the MMI
screen ⇒page 23, fig. 15. The remaining distance to the next
service is updated every time the ignition is switched on (starting at
500 km after a service has been performed).
On a new vehicle, the display will always show the following
message for the first 500 km.
SERVICE IN ----- KM --- DAYS
Caution
The system cannot calculate the figures for the service indicator if
the battery is disconnected from the vehicle, so no service reminder
can be displayed during this time. Please remember that keeping to
the correct service intervals is most important for the service life
and residual value of the vehicle (and especially for the life of the
engine). The period between two services must never be longer than the time specified in the Service Schedule, even if you only
cover a low mileage during this time.
Note
•
Do not reset the display between oil changes - otherwise the
display will be incorrect.
•
The information in the service interval display remains intact if
the battery is disconnected.
•
The distance to the next service cannot be called up if the system
has detected a Priority 1 fault (red symbol).
•
If the service was not performed by a qualified workshop, the oil
change interval display can only be set to “fixed service intervals” of
15,000 km. If you wish to continue with the “LongLife” service, you
will need to have the oil change interval display reset by a qualified
workshop.
