AUC Automatic recirculated-air control/recirculated-air mode You can respond to pollutants or unpleasant odors in the immediate environment by suspending the supply of outside air. The system then recirculates the air currently within the vehicle. During AUC operation, a sensor detects pollutants in the outside air and controls the shut-off automatically. By pressing the button repeatedly, you can request three operating modes: > LED off: outside air flows in continuously. > Right LED on, AUC mode: the system detects pollutants in the outside air and shuts off the supply as needed. > Left LED on, recirculated-air mode: the supply of outside air is permanently shut off. Should the windows fog up in the recirculated-air mode, press the AUTO button or switch off the recirculated-air mode and increase the air volume if necessary. The recirculated-air mode should not be used over an extended period of time, as the air quality inside the vehicle deteriorates continuously.< Air distribution, manual You can route the air flowing out into the vehicle interior via various programs, separately for the driver's and passenger's side: > Upper body region > Upper body region and footwell > Footwell > Driver's side: windows and footwell Selecting program Press the button repeatedly until the desired air distribution of the respective program is shown on the Control Display.
