Air conditioner > Left LED on, AUC mode: a sensor detects pollutants in the outside air. The system suspends the supply of outside air as needed and recirculates the air currently within the vehicle. As soon as the concentration of pollutants in the outside air has decreased sufficiently, the system switches automatically back to supplying outside air. > Right LED on, recirculated-air mode: the outside air supply into the vehicle is shut off continuously. The system then recirculates the air currently within the vehicle. If condensation starts to form on the inside window surfaces during operation in the recirculated-air mode, you should switch it off and increase the air supply as needed. The recirculated-air mode should not be used over a sustained period of time; otherwise, the air quality inside the vehicle will steadily deteriorate.< Ventilation for cooling Adjust the vents to direct the flow of cool air in your direction, for instance, if the interior has become too warm. Draft-free ventilation Set the vent outlets so that the air flows past you and is not directed straight at you. Microfilter/activated-charcoal filter* The microfilter removes dust and pollen from the incoming outside air. The activated-charcoal filter provides additional protection by filtering gaseous pollutants from the outside air. This combined filter is replaced when maintenance is performed by your BMW Sports Activity Vehicle Center. A substantial reduction in air supply indicates that the filter should be replaced before normal maintenance. Rear window defroster The rear window heating switches off automatically after a certain amount of time.
