Activating/deactivating the residual heat function
It is possible to make use of the residual heat of the engine to continue heating the stationary vehicle for up to 30 minutes after the engine has been switched off. The heating time depends on the temperature that has been set.
The blower will run at a low speed regardless of the airflow setting.
If you activate the residual heat function at high temperatures, only the ventilation will be activated. The blower runs at medium speed.
It is possible that the residual heat function may be activated automatically an hour after the SmartKey is removed. The vehicle is then ventilated for 30 minutes to dry the air-conditioning system.
- Turn the SmartKey to position 0 in the ignition lock or remove it.
- To activate: press the button. The indicator lamp in the button lights up.
- To switch off: press the button. The indicator lamp in the button goes out.
Residual heat is deactivated automatically:
- after about 30 minutes
- when the ignition is switched on
- if the battery voltage drops
- if the coolant temperature is too low
