Recirculated air
The system assumes recirculated air mode by pressing the recirculated air button. As a result, the left and right fresh air/recirculated air flaps are closed. The flaps are opened again fro fresh air operation by pressing the button once more. Recirculated air mode is indicated by an LED in the recirculated air button.
The setting on the operating unit for recirculated air mode is saved for 15 minutes after ignition off (exception: Memory function for tropics). The operating unit setting is lost after 15 minutes and must be reselected after switching on the ignition.
