Controls in detail Instrument cluster To brighten illumination Turn reset button 1 in the instrument cluster clockwise. The instrument cluster illumination will brighten. To dim illumination Turn reset button 1 in the instrument cluster counterclockwise. The instrument cluster illumination will dim. Coolant temperature gauge Warning! G ! Excessive coolant temperature triggers the coolant temperature warning lamp ( page 337) and a warning in the multifunction display ( page 371). 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. 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 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. i During severe operating conditions, e.g. stop-and-go traffic, the coolant temperature may rise close to 248°F (120°C). Trip odometer Make sure you are viewing the trip odometer display ( page 139). If it is not displayed, press the j or k button on the multifunction steering wheel repeatedly until the trip odometer appears. Press and hold reset button 1 ( page 136) until the trip odometer is reset. 137
