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.

Turn the SmartKey to position 0 in the ignition lock or remove it.

To activate: press the rocker switch up or down.

The indicator lamp in the rocker switch lights up.

To deactivate: press the rocker switch up or down.

The indicator lamp in the rocker switch 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
