Defrost Function (IHKA High Only)
WARNING: This page does not describe the selected car, but rather 33 other vehicles, including the 2010 BMW M5, 2009 BMW M5, 2008 BMW M5, 2008 BMW 760Li, and 2007 BMW M5. However, it is still accessible from the selected car via links, so may be relevant.
The defrost function is activated with the defrost button in the IHKA controls. This opens the defroster flap (on the inside in front of the windscreen) fully. The fresh-air/airrecirculation flaps move to the "fresh air" position. All other flaps are closed. The blower can be set manually.
