Read and observe on page 35 first.
Stop the vehicle, switch off the engine, and check the engine oil lev-
el » page 142.
The indicator light lights up until the engine reaches operating tempera-
ture2). Avoid high speeds, full throttle and high engine loads.
Even if the oil level is correct, do not drive any further if the warning light is
flashing. Also do not leave the engine running at an idling speed.
If the warning light lights up or flashes, either the coolant temperature is
too high or the coolant level is too low.
Seek help from a specialist garage.
An audible signal sounds as a warning tone.
The warning light lights up yellow (oil quantity too low)
The following message is shown in the MAXI DOT display.
The following message is shown in the MAXI DOT display.

Stop the vehicle, switch off the engine, check the level of the cool-
ant » page 144, and refill the coolant if necessary » page 144.
An audible signal sounds as a warning signal.
If the coolant is within the specified range, the increased temperature may be
caused by an operating problem at the radiator fan. Check the fuse for the ra-
diator fan, replace if necessary » page 170, Fuses in the engine compartment.
The warning light will go out if the bonnet is left open for more than 30 sec-
onds. If no engine oil has been replenished, the warning light will come on
again after driving about 100 km.
Do not continue driving if the warning light does not go off even though
the coolant level is correct and the fuse for the fan is in working order!
The warning light flashes yellow (engine oil level sensor faulty)
The following message is shown in the MAXI DOT display.

Oil sensor workshop!
WARNING
If the engine oil level sensor is faulty, the warning light flashes several
times and an audible signal sounds when the ignition is turned on.
■
If you have to stop for technical reasons, park the vehicle at a safe dis-
tance from the traffic, switch off the engine and activate the hazard warn-
ing light system » page 59.
Carefully open the coolant expansion bottle. If the engine is hot, the cool-
ing system is pressurized - risk of scalding! It is therefore best to allow the
engine to cool down before removing the cap.
Seek help from a specialist garage.

WARNING
If you have to stop for technical reasons, park the vehicle at a safe distance
from the traffic, switch off the engine and switch on the hazard warning
lights system » page 59.
■
Do not touch the radiator fan. The radiator fan may switch itself on auto-
matically even if the ignition is off.
CAUTION
CAUTION
The red oil pressure light is not an oil level indicator! One should therefore
check the oil level at regular intervals, preferably after every refuelling stop.
■
Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.
Never cover the radiator - there is a risk of the engine overheating.
