The activated-charcoal filter provides additional protection by filtering gaseous pollutants from the outside air. Your BMW center replaces this combined filter during routine maintenance. Ventilation for cooling Adjust the vent outlets to direct the flow of cool air in your direction, for instance if it has become too hot in the car. Parked car ventilation The concept The parked car ventilation provides ventilation to the passenger compartment and lowers its temperature, if necessary. It is ready for use at any outside temperature, as of radio readiness. The parked car ventilation remains switched on for approx. 30 minutes. Two different switch-on times can be preselected. The system can also be switched on and off directly. Due to its high power consumption, it should not be switched on twice in a row without driving in between to allow the battery to recharge. The air emerges from the air vents for the upper body area in the instrument panel. The air vents must therefore be open. Draft-free ventilation Set the vent outlets so that the air flows past you and not straight at you. 100 Online Edition for Part no. 01 41 2 603 048 - © 08/09 BMW AG
