Driving systems Coolant temperature gauge The coolant temperature gauge is located on the left side in the instrument cluster (Y page 32). 327 Outside temperature indicator The outside temperature indicator is on the bottom left-hand side of the instrument cluster (Y page 32). G Warning! Fuel gauge The fuel gauge is on the left-hand side of the instrument cluster (Y page 32). Once the fuel level has fallen below the reserve mark, the yellow segment indicator for the fuel reserve comes on. During severe operating conditions, e.g. stopand-go traffic, the coolant temperature may rise close to 248‡ (120†), i.e close to the red zone of the temperature gauge. ! Excessive coolant temperature triggers a warning in the multifunction display. The engine should not be operated with a coolant temperature above 248‡ (120†), i.e. in the red zone of the coolant temperature gauge. Doing so may cause serious engine damage which is not covered by the Mercedes-Benz Limited Warranty. Tachometer The red marking on the tachometer (Y page 32) denotes excessive engine speed.

RParktronic RRear view camera View Assist Plus ASSIST Spot Assist Keeping Assist Z RNight RATTENTION RBlind RLane Controls in detail 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 which can occur just by opening the engine hood. Stay away from the engine if you see or hear steam coming from it. Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of the vehicle and do not stand near the vehicle until the engine has cooled down. G Warning! The outside temperature indicator is not designed to serve as an ice-warning device and is therefore unsuitable for that purpose. Indicated temperatures just above the freezing point do not guarantee that the road surface is free of ice. The road may still be icy, especially in wooded areas or on bridges.
