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. > Left LED on, AUC mode: the system detects pollutants in the outside air and shuts off the supply as needed. > Right LED on, recirculated-air mode: the supply of outside air is permanently shut off. If condensation starts to form on the inside window surfaces during operation in the recirculated-air mode, you should switch it off while also increasing the air volume as required. The recirculated-air mode should not be used over an extended period of time, as the air quality inside the vehicle deteriorates continuously.< REST appears on the display of the automatic climate control when the residual heat utilization is switched on. From radio readiness the interior temperature, the air volume and the air distribution can be set. If the conditions for the residual heat utilization are met, no display appears.< Switching off residual heat utilization You can select the lowest blower speed by pressing and holding the left side. Pressing again switches off the residual heat utilization. REST disappears from the display of the automatic climate control. Switching off automatic climate control You can select the lowest blower speed by pressing and holding the left side. Pressing again switches off the automatic climate control. The air volume, the heater and the cooling function are all switched off. You can switch on the system again by pressing any button of the automatic climate control. Front ventilation Residual heat The heat stored in the engine is used to heat the passenger compartment, e.g. while stopped at a school to pick up a child. Switching on residual heat utilization Pressing the right side switches on the residual heat utilization when the following conditions are met: > up to 15 minutes after switching off the engine > with the engine at operating temperature > with sufficient battery voltage > at an outside temperature below 777/ 25 6 1 2 Knurled wheels to smoothly open and close air vents Levers to change the air vent direction 105 Online Edition for Part no. 01 41 0 012 501 - © 08/06 BMW AG Reference Mobility Do not drop any foreign objects into the air vents, otherwise these could be catapulted outwards and lead to injuries.< Communications Entertainment Navigation Driving tips Controls At a glance
