The following message is shown in the MAXI DOT display.
ENGINE COOLANT PLEASE CHECK Log book!
Stop the vehicle, switch off the engine, check the level of the coolant » page 162,
and refill the coolant if necessary » page 163.
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 radia-
tor fan, replace if necessary » page 192, Fuses in the engine compartment.
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!
Seek help from a specialist garage.
WARNING
■If you have to stop for technical reasons, then park the vehicle at a safe dis-
tance from the traffic, switch off the engine and activate the hazard warning
light system » page 41.
■Carefully open the coolant expansion bottle. If the engine is hot, the cooling
system is pressurized – risk of scalding! It is therefore best to allow the engine
to cool down before removing the cap.
■Do not touch the radiator fan. The radiator fan may switch itself on auto-
matically even if the ignition is off.
