Controls in detail Instrument cluster Tachometer The red marking on the tachometer denotes excessive engine speed. Outside temperature indicator 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. This means that the accuracy of the displayed temperature 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. Warning! G ! Avoid driving at excessive engine speeds, as it may result in serious engine damage that is not covered by the Mercedes-Benz Limited Warranty. To help protect the engine, the fuel supply is interrupted if the engine is operated within the red marking. CLK 55 AMG The tachometer of the CLK 55 AMG does not have a red marking denoting excessive engine speed. To help protect the engine, the fuel supply is interrupted if the engine is operated at an excessive engine speed. 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. The outside temperature is displayed in the multifunction display ( page 22). For information on how to select the unit of the displayed temperature, i.e. degrees Celsius (°C) or degrees Fahrenheit (°F), see "Selecting temperature display mode" ( page 142) 128
