You can activate and deactivate the gear-change indicator
on the sound system or MMI*.
Switching the gear-change indicator on and off
– Select: Function selector button > Instrument cluster > Suggested gear ⇒ fig. 12.To familiarise yourself with the gear-change indicator, we recom-
mend driving in the normal way to start with. A gear change will be
recommended if the gear you are in is not the most economical
choice. The gear you are currentl y in and the recommended gear
will be displayed ⇒page 22, fig. 11.•
Shifting up a gear: The suggested gear appears to the right of the
current gear when a higher gear is recommended.
•
Shifting down a gear: The suggested gear appears to the left of
the current gear when a lower gear is recommended.
Gears may ocassionally be skipped (3 > 5). If no gear-change is
recommended, you are already in the most economical gear.Note
•
The gear-change indicator is intended to help save fuel. It is not
intended to recommend the right gear for all driving situations. In certain situations, only the driver can choose the correct gear (for
instance when overtaking, driving up a steep gradient or towing a
trailer).
•
The gear-change indicator in the instrument cluster
⇒page 22,
fig. 11 goes out when you press the clutch pedal.

The pictogram shows whether th e doors and the boot lid,
etc. are properly closed when driving off.The door catches/boot lid warning symbol lights up if one or more
of the doors, or the bo nnet or boot lid are not properly closed when
the ignition is on. The symbol also indicates which of these is not
properly closed ⇒fig. 14.
The warning symbol disappears when all the doors, the bonnet and
the boot lid are completely closed, and the driver information func-
tions selected will then be displayed again.

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.

Press RESET button
⇒fig. 20 to switch back and forward
between the functions of on-board computers 1 and 2.
The number in the display ⇒page 26, fig. 19 indicates which of the
two memories is currently in use. The figure 1 means that the
display is showing the information in the single journey memory
(on-board computer 1). The figure 2 means that the display is
showing the information in the total journey memory (on-board
computer 2).
Single journey memory (on-board computer 1)
The single journey memory processes the information on a journey
from the time the ignition is switched on until it is switched off. If
the journey is resumed within two hours after the ignition is
switched off, the new figures are automatically included in the
calculation. The memory is automatically deleted when you resume
driving, if the journey is interrupted for more than two hours.
Total journey memory (o n-board computer 2)
Unlike the single journey memory, the total journey memory is not
erased automatically. In this way, you can determine the period for
which you wish the on-board computer to supply figures.
Applies to vehicles: with on-board computerControls
The on-board computer is controlled by means of two
switches on the windscreen wiper lever.– Press the top or bottom of the function selector switch ⇒ fig. 20. This displays the on-board computer read-
outs one after the other.The on-board computer can only be operated while the ignition is
switched on. When the ignition is switched on, the display shows
the function that was last selected.
As well as the figures from the on-board computer (computer 1 or
2), the display can also show information from other systems. Press
the Reset button briefly to switch back and forward between
these displays.
Resetting figures to zero
To cancel one of the computer readings individually, select the
required function and press the RESET button for at least one
second. The following values can be reset to zero individually using

sponding figures will still be registered by the on-board computer and can be switched back
on at any time so that they again appear
in the display.
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

Speed limit warning 2 can be adjusted in increments of 10 km/h
between 30 and 240 km/h.
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 yello w 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 stationary apply foot brake while selecting gear
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 assi
st the driver are displayed
together with the warning symbols in the instrument
cluster.For example, the following driver me ssage will appear if the selector
lever for the automatic gearbox* is not in position P when you
switch off the engine:
Shift to P, otherwise vehicle can roll away. Doors do not lock if
lever is not in P.
The ignition key can only be withdrawn when the selector lever is in
this position. Similar messages will be displayed if other functions
of this kind cannot be carried out.
Driver messages and red symbols
If a red warning symbol appears in the display, it will automatically
be accompanied by the corresponding driver message.
