
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.

Instruments and warning/indicator lamps
20When the vehicle has been stationary for an extended period, Audi
hold assist will automatically appl y the parking brake. In this case,
the green symbol
 will change to red
.
Electro-mechanical parking brake

This warning lamp monitors the electro-mechanical
parking brake.The warning lamp
 lights up when the parking brake is applied
with the ignition on. After the ig nition has been switched off the
lamp will stay on for about 30 seconds. The warning lamp will light
up for about 30 seconds if the parking brake is applied with the igni-
tion switched off.
The warning lamp should go out when the parking brake is released.
If the warning lamp flashes continuously after the parking brake has
been applied , the brake may not be strong enough to hold the
vehicle on a slope. This may be due to the brakes overheating.
Please note the following points:
•
If the gradient is too steep to park the vehicle safely, the display
will show the message Caution: Vehicle parked too steep .
•
In the event of a fault in the parking brake system the symbol

will also appear in the instrument cluster display together with the
message Parking brake! You should have the fault corrected by a
qualified workshop without delay.
Brake system

The warning lamp flashes if the brake fluid level is too low
or if there is a fault in the ABS system or the parking
brake.If the warning lamp
 flashes, there is a fault in the brake system.
The symbol
 in the instrument cluster display will flash at the same time. You can press the button to obtain a message
explaining the fault
⇒page 32 .
If a failure should occur in the ABS, the ABS warning lamp
 will
light up together with the brake warning lamp
 ⇒ .
WARNING
•
Before opening the bonnet and ch ecking the brake fluid level,
observe the warning information on ⇒page 255, “Working on
components in the engine compartment”.
•
If the brake warning lamp does not go out, or if it lights up
when driving, the brake fluid level in the reservoir is too low – this
may cause an increased accident risk. Stop the vehicle and do not
drive on. You should obtain professional assistance.
•
If the brake warning lamp lights up together with the ABS
warning lamp, this can mean that the control function of the ABS
is out of action. As a result the rear wheels can lock relatively
easily when braking. This could caus e the tail of the vehicle to skid
sideways. Drive carefully to the nearest qualified workshop and
have the fault rectified.

Driver 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 info rmation 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 sound system or 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 31 . A yellow warning symbol indicates a less serious
malfunction, or other item requiring attention ⇒page 35 .

temperature display. This is to warn the driver to take extra care
when there is a risk of ice on the road.
When the vehicle is stationary or travelling at very low speeds, the
temperature displayed may be slig htly higher than the actual
outside temperature as a result of the heat radiated from the
engine.
The temperature units can be set to °F or °C on the sound system or
MMI* system. The outside temperatur e is automatically displayed in
the units you have selected. Please refer to the sound system or
MMI* Operating Manual for further details.

the number of kilometres reaches ze
ro, even if the estimated period
has not yet expired. The remaining distance and time are updated
and displayed briefly each time you switch on the ignition.
•
Service due: When a service is due, Service due! will appear in
the display as soon as you switch on the ignition. The display reverts
back to the standard display after a short time. In addition, a tone
will sound.
Displaying distance and time to next service
In the Car menu, you can look up the distance and time remaining
until the next oil change and next service inspection. To do this,
select function selector button > Service interval display
⇒ page 24, fig. 16.
The display may not be complete on new vehicles within the first
500 km.
Resetting the service interval display
Your Audi dealer resets the display after each service. You can only
reset the oil change display yourself. To do this, select function
selector button > Service interval display > Reset oil change
interval . The next oil change will be indicated as being due
15,000 km or one year (fixed serv ice interval) after the oil change
interval is reset.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 betwee n 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.

Driver information system
26The following items of information are processed by the on-board
computer and can be shown one afte r the other on the display in the
instrument cluster.
Fuel range
The estimated fuel range is displayed in km. It shows how far the
vehicle can be driven with the amount of fuel left in the tank,
assuming the same style of driving. The fuel range is displayed in
increments of 10 km.
The fuel range is calculated on the basis of the fuel consumption
over the last 30 kilometres. The fuel range will increase accordingly
if you drive in a more economical manner.
Average fuel consumption
This mode displays the average fuel consumption since the memory
was last cancelled in litres/100 km. If required, you can use this
display to adjust your driving style to achieve the desired fuel
consumption.
Current fuel consumption
The display shows the current fuel consumption in litres/100 km. If
required, you can use this display to adjust your driving style to
achieve the desired fuel consumption.
The computer calculates the fuel consumption every 30 metres. The
display switches to l/h (litres per hour) when the vehicle is
stationary. Average speed
This mode shows the average speed driven since the memory was
last cancelled (in km/h).
Driving time
This display shows the period of time which has elapsed since the
memory was last cancelled.
Distance covered
This display shows the distance you have covered since the memory
was last cancelled.
Note
•
The displays for fuel consumption (average and current
consumption), fuel range and speed are shown in metric units. You
can change the measurement unit s via the sound system or MMI*.
•
The information in the memory is cancelled if the battery is
disconnected.
