Controls in detail Instrument cluster To help protect the engine, the fuel supply is interrupted if the engine is operated within the red marking. Outside temperature indicator The outside temperature indicator is on the bottom left-hand side of the instrument cluster ( page 28). Warning! ature can only be verified by comparison to a thermometer placed next to the sensor, not by comparison to external displays (e.g. bank signs, etc.). When moving the vehicle into colder ambient temperatures (e.g. when leaving your garage), you will notice a delay before the lower temperature is displayed. A delay also occurs when ambient temperatures rise. This prevents inaccurate temperature indications caused by heat radiated from the engine during idling or slow driving. Fuel gauge The fuel gauge is on the left-hand side of the instrument cluster ( page 28). Once the fuel level has fallen below the reserve mark, the yellow segment indicator for the fuel reserve comes on ( page 605). of the vehicle and do not stand near the vehicle until the engine has cooled down. ! Excessive coolant temperature triggers a warning in the multifunction display ( page 646). The engine should not be operated with the coolant temperature above 248°F (120°C), 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. G i During severe operating conditions, e.g. stop-and-go traffic, the coolant temperature may rise close to 248°F (120°C), i.e. close to the red zone of the temperature gauge. 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. Tachometer The red marking on the tachometer denotes excessive engine speed. ! Avoid driving at excessive engine speeds, as it may result in serious engine damage that is not covered by the Mercedes-Benz Limited Warranty. The temperature sensor is located in the front bumper area. Due to its location, the sensor can be affected by road or engine heat during idling or slow driving. Therefore, the accuracy of the displayed temper- 418
