Independent Ventilation Function
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 independent ventilation function is activated either via the Central Information Display (CID) or via Telestart (through the Car Access System (CAS)). There are 2 ways of activating the system via the CID:
Direct operation or programming using the timer.
If the independent ventilation function is programmed via the timer, the independent ventilation function will only be available at exterior temperatures above 15 °C. The battery's charge level is constantly monitored by the intelligent battery sensor throughout the independent ventilation function. If the necessary charge level is not maintained, the IHKA control unit will deactivate the independent ventilation function.
