Coolant Temperature Gauge; Display In The Speedometer - Mercedes-Benz 2003 M-Class Operator's Manual

Coolant temperature gauge

Under normal driving conditions, the cool-
ant temperature may rise to 248°F
(120°C). The coolant temperature may
climb to the red marking:
at high outside temperatures
during stop-and-go city traffic
when driving on hilly terrain
The engine should not be operated with
the coolant temperature in the red zone.
Doing so may cause serious engine dam-
age which is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
Driving when your engine is badly overheat-
ed can cause some fluids which may have
leaked into the engine compartment to
catch fire. You could be seriously burned.
Steam from an overheated engine can cause
serious burns and can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until it
cools down.
