78•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. Under
certain circumstances, the rear of the vehicle could suddenly sway from
side to side, with the subsequent dang er of skidding. Drive carefully to the
nearest specialist garage and have the fault rectified.
Fault in the cooling system
Faults in the cooling system must be rectified immediately.If the
symbol flashes in the display, this means that either the
coolant temperature is too high or the coolant level is too low. The
following message will appear in the display together with the
symbol:
Switch off engine and check coolant level
– Stop the vehicle.
– Switch the engine off.
– Check the coolant level ⇒page 232.
– Add more coolant if necessary ⇒page 233.
– Wait for the symbol to go out before driving on.
– Obtain professional assistance if necessary.
If the coolant level is correct, the overheating may be caused by a malfunction
of the radiator fan. If the alternator warning lamp lights up as well
⇒page 69, it is possible that
the drive belt has broken.
Caution
Do not drive on if the symbol
has come on to indicate a fault in the cooling
system, otherwise there is a risk of engine damage.
Engine oil pressure too low
If the engine oil pressure is too low the fault must be rectified
immediately.If the
symbol flashes in the display, the oil pressure is too low.
The following message will appear in the display together with the
symbol:
Switch off engine, check oil level
– Stop the vehicle.
– Switch the engine off.
– Check the engine oil level ⇒page 230.
– Obtain professional assistance if necessary.
Engine oil level too low
If the engine oil level is too low, add more oil ⇒page 230.
Engine oil level correct
If the
symbol flashes and the engine oil level is correct, obtain profes-
sional assistance. Do not drive on. Do not continue to run the engine, even at
idle speed .

80Brake light failure
This warning light will appear on the upper part of the display if any of the
brake lights has failed. A text message in the central part of the display indi-
cates which brake light has failed (left or right).Fuel level low
When this symbol
comes on for the first time, there are about 8 to 10 litres
of fuel left in the tank. You should fill up as soon as possible ⇒page 222.
Check engine oil level
If the
symbol lights up, please check the engine oil level as soon as
possible ⇒page 230. Top up the oil at the next opportunity ⇒page 230.
Engine oil sensor defective*
If the
symbol lights up, take the vehicle to a qualified workshop and have
the oil level sensor checked. Until then it is advisable to check the oil level
every time you fill up with fuel ⇒page 230.
Diesel particulate filter obstructed
If the symbol
lights up, you may be able to contribute towards automatic
filter cleaning by driving in the right manner. To do this, drive about 15
minutes in 4th or 5th gear (automatic gearbox: S gear range) at a speed of 60 km/h, with the engine running at approximately 2000 rpm. The increase in
temperature will burn off any soot in the filter. When cleaning is successful,
the symbol switches off.
If the light on symbol
does not go off, take the vehicle to a specialist
garage to repair the fault.
For further information on the diesel particulate filter, see ⇒page 197.
WARNING
It is essential that you adjust your speed to suit the weather, road, terrain
and traffic conditions. The recommended driving speed must never lead to
the driver disregarding the traffic regulations.Light sensor/ rain sensor faulty
Automatic headlights / automatic wipers faulty
If the symbol appears, this means that the light sensor / rain sensor is not
working. For safety reasons, the dipped beam headlights will then be
switched on permanently when the light switch is set to the AUTO position.
However, you can still switch the lights on and off in the normal way with the
light switch. If the rain sensor is faulty, the functions operated via the wind-
screen wiper lever will still be available. You should have the light sensor /
rain sensor checked by a specialist garage as soon as possible.
Worn brake pads
If the
symbol lights up, have the front brake pads (and, for safety's sake,
the rear pads as well) inspected by a specialist garage.

Speed warning
Introduction
The speed warning function can help prevent you exceeding
a particular pre-set maximum speed.The speed warning function will warn the driver if a pre-set maximum speed
is exceeded. The system gives an audible warning signal if the set speed is
exceeded by about 10 km/h. A warning symbol will also appear in the display
⇒ fig. 56.
The speed warning function has two different warning speeds, which operate
independently and serve slig htly 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 warning 1
⇒page 82, fig. 56
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. However, this does not
cancel the speed limit that was originally set.
Setting speed limit warning 1 ⇒page 83.
Speed limit warning 2
With speed limit warning 2, the speed limit can only be changed or cleared
when the ignition is switched off. 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 a
particular speed should not be exceeded 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
set value again.
Setting speed limit warning 2 ⇒page 84.
Note
Please bear in mind that, even with the speed warning function, it is still
important to keep a eye on the car's speed with the speedometer and to
observe the legal speed limits.
Setting speed limit warning 1
Use the CHECK button to set speed limit warning 1.Setting the speed limit
– Drive at the desired maximum speed.
– Press the CHECK button and hold it down until the symbol
⇒page 82, fig. 56 appears.
Clearing the speed limit
– Drive the vehicle at a minimum of 5 km/h.
– Press the CHECK button for at least two seconds.The speed warning symbol
lights up briefly in the display when the button
is released to confirm that the selected speed has been stored. The speed
limit that has been selected remains stored until another speed is selected
