During severe operating conditions and stop-and-go city
traffic, the coolant temperature may rise close to 120 ° C.
The engine should not be operated with the coolant
temperature above 120 ° C. Doing so may cause serious
engine damage which is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
Driving when your engine is badly overheated 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.
