Automatic Air Recirculation
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.
In automatic mode, the system will automatically switch to air-recirculation mode if an extreme cooling output is called for. This allows the vehicle interior to be cooled more quickly. Air from the vehicle interior that has already been cooled is fed through the evaporator again. This reduces the temperature level much faster than it would in normal operation.
Automatic air-recirculation mode initially runs for 12 minutes in full air-recirculation mode and then continuously in partially fresh-air mode (fresh-air flap opening angle: approx. 10 %).
