Instrument cluster
Coolant temperature gauge
The coolant temperature gauge is on the left side in the instrument cluster (▷ page 24).
Warning!
- Driving when your engine is badly 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 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.
During severe operating conditions, e.g. stop-and-go traffic, the coolant temperature may rise close to 248°F (120°C).
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.
Trip odometer
▶ Make sure you are viewing the trip odometer and main odometer in the multifunction display (▷ page 129).
▶ If it is not displayed, press button [icon] or [icon] on the multifunction steering wheel (▷ page 130) until the trip odometer appears in the multifunction display.
▶ Press and hold the reset button in the instrument cluster (▷ page 126) until the trip odometer is reset.

Tachometer
The red marking on the tachometer (▷ page 24) 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.
To help protect the engine, the fuel supply is interrupted if the engine is operated within the red marking.
Outside temperature indicator
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.
The outside temperature is indicated in the multifunction display (▷ page 129). For information on how to select the unit of the indicated temperature, i.e. degrees Celsius (°C) or degrees Fahrenheit (°F), see "Selecting temperature display mode" (▷ page 143).
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.
