Technical data
Applies to vehicles: with cruise control systemCruise control
The indicator lamp
in the instrument cluster lights up when the
cruise control system is operating.
Anti-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 222.
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 32, 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 32.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 222.
WARNING
•
Before opening the bonnet and checking the brake fluid level,
observe the warning information on ⇒page 255, “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.

Instruments and warning/indicator lamps 20When 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
.
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 ignition 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 checking 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 cause the tail of the vehicle to skid
sideways. Drive carefully to the nearest qualified workshop and
have the fault rectified.

control, the name or frequency of the current radio station and the
selected waveband will appear the upper part of the display.
When a CD is playing, the display will show the current title. If the
vehicle is equipped with a CD changer* the display will also show
the number of the CD being played (CD1 to CD6).Outside temperature display
The outside temperature is shown when the display is
activated.
At temperatures below +5°C a snowflake symbol appears next to the
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 slightly 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 temperature is automatically displayed in
the units you have selected. Please refer to the sound system or
MMI* Operating Manual for further details.

Speed warning functionApplies to vehicles: with speed warning functionIntroduction
The speed warning function can help you keep below a
pre-set maximum speed.The speed warning function will warn you if the vehicle exceeds the
pre-set maximum speed. The system gives an audible warning
signal if the set speed is exceeded by about 3 km/h. A warning
symbol will also appear in the display . On some models the symbol
may look slightly different.
The speed warning function has two different warning speeds,
which operate independently and serve slightly different purposes:
Speed limit warning 1
With speed limit warning 1, the maximum speed can be changed
while driving. The speed limit that has been set remains stored until
the ignition is switched off, or until it is changed or cleared.
The speed limit warning symbol
for speed limit warning 1 will
appear in the display if you exceed the pre-set speed. It goes out
again if the speed is reduced below the set speed limit.
The symbol also goes out if the speed is increased to more than
about 40 km/h above the set speed for at least 10 seconds. This
cancels the speed limit that was originally set.
Setting speed limit warning 1 ⇒page 29.
Speed limit warning 2
You are recommended to store this speed limit warning if you
always wish to be reminded of a particular speed limit. This could
be when driving in countries with general speed limits, or if you

Auto-check controlIntroductionThe auto-check control checks important components and vehicle
systems. These background checks are run constantly, as long as
the ignition is switched on.
A message is displayed in the instrument cluster if a fault should
occur or if any maintenance or repairs are urgently required. This is
accompanied by an audible warning signal. Depending on the
priority of the fault, a red or yellow warning symbol lights up in the
display.
The red symbols indicate a serious malfunction, whereas the yellow
ones represent other malfunctions or items requiring attention.
Additional messages to assist the driver may be shown with the red
or yellow symbols.
Automatic gearbox* function test
The auto-check control automatically checks the vehicle systems
when the ignition is switched on. If the selector lever is in position
P or N, the following instruction will appear:

When a gear (R, D etc.) is selected, this message disappears and the
auto-check control function is displayed.
The driver message will disappear 30 seconds after switching on
the ignition or earlier, if there are other driver messages or malfunc-
tions.If one or more faults are detected, the driver information message
(as above) will disappear about 15 seconds after the engine has
been started and the appropriate fault symbol(s) will appear in the
display. The warning display will be accompanied by the corre-
sponding warning chime.
Applies to vehicles: with speed warning functionDriver messages
Additional messages to assist the driver are displayed
together with the warning symbols in the instrument
cluster.For example, the following driver message will appear if the selector
lever for the automatic gearbox* is not in position P when you
