2005 Mercedes-benz C Class Owners Manual

Driving when your engine is badly over- heated 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 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 the engine has cooled down.

Practical hints What to do if …

Possible solution 왘 Stop the vehicle and turn off the

engine.

왘 Only start the engine again after the

message disappears. You could otherwise damage the engine.

The engine should not be operated with the coolant temperature above 248°F (120°C). Doing so may cause serious engine damage which is not covered by the Mercedes-Benz Limited Warranty.
