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 .

Tyre pressure monitoring*Introduction
The tyre pressure monitoring system constantly checks the
pressure of the tyres.The system warns the driver in the event of a loss of pressure by means of
symbols and messages in the instrument panel display. The system works
with the help of the ABS sensors in the wheels.
Please bear in mind that the tyre inflation pressure is also influenced by the
temperature of the tyre. Tyre pressure increases about 0.1 bar for each 10°C
in tyre temperature increase. The tyre heats up while the vehicle is being
driven and the tyre pressure will rise accordingly. Therefore, you should only
adjust the tyre pressures when they are
cold (i.e. approximately at ambient
temperature).
To ensure that the tyre pressure monitoring system works reliably, you should
check and, if necessary, adjust the tyre pressures at regular intervals and
store the correct pressures (reference values) in the system.
A tyre pr essure i nfor ma ti on lab e l is a tta che d to t he insi de o f the fu el ta nk f lap.
WARNING
•Never adjust tyre pressure when the tyres are hot. This may damage or
even burst the tyres. Risk of accident!•An insufficiently inflated tyre flexes a lot more at high speeds and
causes significant heating of the tyre. Under these conditions, the tyre
bead may be released or the tyre may burst. Risk of accident!For the sake of the environment
Under-inflated tyres lead to increased fuel consumption and tyre wear.
Note
•Responsibility for ensuring that the tyres are correctly inflated remains
with the driver; the system can only provide assistance.•Pressure can only be adjusted when the tyres are at ambient
temperature.

The tyre pressure should be corrected as soon as possible if
it is too low.If the
symbol appears, the tyre pres sure on at least one of the
wheels is too low.
– Stop the vehicle.
– Check the tyre(s).
– Correct the tyre pressure ⇒page 243.
