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.

If you activate the residual heat function at high temperatures, only the ventilation will be activated. The blower runs at medium speed.
Turn the SmartKey to position 0 in the ignition lock or remove it.

To deactivate: press the rocker switch up or down.
The indicator lamp in the rocker switch goes out.

automatically:
