Practical hints What to do if ... Display symbol Display message Possible cause/consequence Possible solution Observe the coolant temperature in the multifunction display ( page 164). If the temperature rises again: Contact an authorized Mercedes-Benz Light Truck Center immediately. Warning! G During severe operation conditions and stop-and-go city traffic, the coolant temperature may rise close to 248°F (120°C). Driving when your engine is 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 the engine has cooled down. ! The engine should not be operated with the coolant temperature above 248°F (120°C). Doing so may cause serious damage which is not covered by the Mercedes-Benz Limited Warranty. 449
