The needles on the dials in the instrument cluster are illuminated
when the ignition is switched on. The main instrument lighting (for
the dials and needles) comes on when the vehicle's lights are
switched on.
Engine oil temperature gaugeThe engine oil temperature gauge ⇒fig. 2 only works when the igni-
tion is switched on. In order to avoid possible damage to the engine,
please read the following notes for the different temperature
ranges.
Engine cold
If the needle is still in the lower range of the dial, this indicates that
the engine oil has not yet reached operating temperature. Avoid
high engine speeds, full acceleration and heavy engine loads.
Normal temperature
In normal operation the needle will settle somewhere in the centre
of the dial once the engine has reached operating temperature. The
needle may also go further up when the engine is working hard at
high outside temperatures. This is no cause for concern provided
the warning lamp
in the display does not start flashing.
Warning lamp
If the symbol
in the display flashes, either the engine oil temper-
ature is too high, or the engine oil level is too low ⇒page 157.
If the needle is at the top end of the dial, this means the engine oil
temperature is too high. Stop the vehicle, switch off the engine and
wait for it to cool down. If the warning lamp starts flashing again
after just a short distance, contact a qualified workshop.

Technical data Warning lamp
If the symbol
flashes in the display, this means that either the
coolant temperature is too high or the coolant level is too low
⇒page 35.
If the needle is over to the far right on the dial, this means the
coolant temperature is too high. Stop the vehicle, switch off the
engine and wait for it to cool down. If the warning lamp starts
flashing again after just a short distance, contact a qualified work-
shop.
WARNING
•
Before opening the engine lid and checking the coolant level,
please observe the warning information on ⇒page 155, “Working
on components in the engine compartment”.
•
Never open the engine lid if you can see or hear steam or
coolant escaping from the engine compartment; there is a risk of
being scalded. Wait until you can no longer see or hear escaping
steam or coolant.Caution
•
Additional lights and other accessories in front of the air inlet
reduce the cooling effect of the radiator. At high outside tempera-
tures and high engine loads, there is a risk of the engine over-
heating.
•
The front spoiler also ensures proper distribution of the cooling
air when the vehicle is moving. If the spoiler is damaged this can
reduce the cooling effect, which could cause the engine to overheat.
You should obtain professional assistance.
Fuel gaugeThe gauge only works when the ignition is switched on. When the
needle reaches the reserve zone, the symbol
lights up in the instrument cluster display ⇒page 36. At this point there are still
about 10 litres of fuel left in the tank. This is your reminder to fill up
soon.
The tank capacity of your vehicle is given in the Technical data
section ⇒page 198.
Caution
Never run the tank completely dry. If there is an irregular fuel supply,
misfiring can occur. This allows unburnt fuel to enter the exhaust
system, which could cause overheating and damage the catalytic
converter.Speedometer with mileage recorder
This instrument indicates the speed of the vehicle and the
distance travelled.The mileage is normally stated in kilometres (km). On some models,
however, the mileage recorder will show miles.
Lower mileage recorder (odometer)
The lower counter records the vehicle's total mileage.

cluster ⇒page 32, fig. 29. The mileage recorder display
and the digital clock will light up.
– Press the adjuster/test button for at least 2 seconds. The
display will show the speed limit which is currently set.
– Now press and hold the button on the wind-
screen wiper lever ⇒page 32, fig. 30 until the
crossed-out warning symbol for speed limit 2 appears on
the display.The display lighting for the mileage recorder and digital clock goes
off again a few seconds after the button is released.
Note
This speed limit function can also be operated via the on-board
computer ⇒page 25, “Selecting options from the menu”.Notes and symbolsRed symbols
A red symbol warns of a serious malfunction.–Stop the vehicle.
– Switch off the engine.
– Check the function displayed. Obtain professional assist-
ance if necessary.
A red symbol is accompanied by three warning chimes. The symbol
will keep flashing until the fault is corrected. If several faults are
detected at the same time, the symbols are displayed one after the
other for about 2 seconds at a time.
Note
•
You can press the left adjuster button to display a message that
gives you more information.
•
On vehicles equipped with a navigation system the warning
symbol is displayed in the top section of the display while the route
guidance is active.
