Overheating in the engine and drive system
Under certain conditions, e.g. hard driving in hilly terrain and hot climate, there is an increased risk of overheating the engine and drive system – in particular with a heavy load.
- In the event of overheating, the engine's power may be limited temporarily.
- Remove any auxiliary lamps from in front of the grille when driving in hot climates.
- If the temperature in the engine's cooling system becomes too high then a warning symbol is illuminated and the driver display shows the message Stop safely High engine temperature. Stop the car in a safe way and allow the engine to run at idling speed for several minutes and cool down.
- If the message Turn off engine High engine temperature or Turn off engine Coolant level low is shown, stop the car and switch off the engine.
- A built-in protection function is activated if the transmission overheats. A warning symbol illuminates and the driver display shows the Reduce speed to lower temperature Transmission warm or Stop safely Transmission hot Wait for cooling message. Follow the recommendation given, reduce speed or stop the car in a safe way and allow the engine to run at idling speed for several minutes to enable the gearbox to cool down.
- If the car overheats, the air conditioning may be switched off temporarily.
- Do not turn the engine off immediately you stop after a hard drive.
Note
It is normal for the engine's cooling fan to operate for a time after the engine has been switched off.
