automatic climate control does not have enough time to achieve the set temperature.< Ventilation Switch on the desired operating mode by pressing this button repeatedly: > LEDs off: outside air flows in continuously. > Left-hand LED on, AUC mode: a sensor detects pollutants in the outside air. If necessary, the system blocks the supply of outside air and recirculates the inside air. As soon as the concentration of pollutants in the outside air has decreased sufficiently, the system automatically switches back to outside air supply. > Right-hand LED on, recirculated-air mode: the inflow of outside air is shut off permanently. The system recirculates the air within the vehicle. If the windows fog over in the recirculated-air mode, you should switch it off and, if necessary, increase the air flow rate. The recirculated-air mode should not be used over an extended period of time, otherwise the air quality inside the car will deteriorate continuously.< 1 2 Knurled wheels to set any vent position from fully open to closed Slide for adjusting air flow direction Adjust the vent outlets to direct the flow of cool air toward you, for instance if it has become too hot in the car. Draft-free ventilation Set the vent outlets so that the air flows past you and not straight at you. Driving tips Reference Mobility 67 Microfilter/activated-charcoal filter The microfilter removes dust and pollen from the incoming air. The activated-charcoal filter provides additional protection by filtering gaseous pollutants from the outside air. Your BMW center replaces this combined filter during regular maintenance. A substantial reduction in air flow indicates that the filter needs to be replaced earlier. Rear window defroster The defroster switches off automatically after a certain time.
