Driver information system
Introduction
General 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.

CD and radio display
If no priority 1 or 2 faults have been detected by the auto-check
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 MMI* or sound
system control console. The outside temperature is automatically
displayed in the units you have selected. Please refer to the Oper-
ating Manual for the MMI* or sound system.
WARNING
Do not rely on the outside temperature display as an ice warning.
Please bear in mind that there may be patches of ice on the roads
even at outside temperatures around +5°C.
Applies to vehicles: with manual gearbox and gear-change indicator

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 for the current driving conditions. The gear you are currently
in and the recommended gear will be displayed ⇒ page 21, 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. For
example, the display may not recommend a gear change while you
are overtaking, driving up a steep gradient or towing a trailer.
• The gear-change indicator goes out when you press the clutch
pedal.

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.

On-board computer
Applies to vehicles: with on-board computer
Introduction
The on-board computer provides you with useful informa-
tion during a journey, including average and current fuel
consumption, average speed, fuel range and driving time.
The following items of information are processed by the on-board
computer and can be shown one after 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 units on the MMI display.
• The information in the memory is cancelled if the battery is
disconnected.
Applies to vehicles: with on-board computer
Memory
The on-board computer has two automatic journey
memories.
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 ⇒ 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 (on-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 computer
Controls
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 the digital speedom-

Speed warning function
Applies to vehicles: with speed warning function
Introduction
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 28.
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
need to keep below a particular speed when winter tyres are fitted,
etc.
The speed limit warning symbol for speed warning 2 will appear
in the display if you exceed the pre-set speed. Unlike speed limit
warning 1, the warning symbol only goes out once the road speed
has dropped below the stored value again.
Setting speed limit warning 2 ⇒ page 29.
Note
Please bear in mind that, even with the speed warning function, it is
still important to keep a check on the car's speed with the speedom-
eter and to observe the statutory speed limits.
Applies to vehicles: with speed warning function
Setting speed limit warning 1
You can use the button to set, alter or cancel speed
limit warning 1.

Clearing speed limit
– Drive the vehicle at a minimum of 5 km/h.
– Press the button for at least 2 seconds.
The speed warning symbol lights up briefly in the display to
confirm that the selected speed has been stored. The speed limit
that has been set remains stored until another speed is set with a
brief push of the button, or until the memory is cleared with a long
push of the button.
When the speed limit has been cleared, the display will show a
crossed-out warning symbol .
Applies to vehicles: with speed warning function
Setting speed limit warning 2
You can use the MMI* or sound system control console to
set, alter or cancel speed limit warning 2.
– Select: Function selector button > Instrument

between 30 and 240 km/h.
Auto-check control
Introduction
The 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 stationary apply footbrake 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.

components in the engine compartment”.
• If the brake fluid level in the reservoir is too low, this could
result in an accident. Do not drive on. You should obtain profes-
sional 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.
Note
The warning lamp in the instrument cluster will start flashing as
well if there is a fault in the brake system.
Fault in the cooling system
Faults in the cooling system must be rectified immedi-
ately.
If the symbol flashes in the display, this means that
