Automatic Air Quality Control (AUC)/Recirculation Mode

If there is an unpleasant odor from outside or exhaust fumes, the supply of outside air to the interior can be shut off. In this case, the air inside circulates in a closed loop. When the AUC system is operating, the sensor detects exhaust fumes and automatically shuts off the supply of outside air.

Press the button repeatedly to cycle through three modes:

► LEDs off – outside air is supplied.
► Left LED on – AUC mode:

the system detects harmful substances and shuts off the supply of outside air to the interior if necessary.

► Right LED on – recirculation mode: supply of outside air is completely stopped.

If the windows fog up in recirculation mode, press the AUTO button or switch off recirculation mode and increase the air volume if necessary.

Do not leave recirculation mode on for a long time, otherwise the cabin air quality will deteriorate.◄
