Activating/deactivating the residualheat 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.
