Program for avoiding condensation on the window surfaces (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.
Measures to prevent condensation on the windscreen depend on a number of conditions:
- The engine must be running
- The IHKA must be in automatic mode
The IHKA control unit evaluates condensation sensor signal (humidity). If condensation on the windscreen is imminent, the following measures are initiated in turn until the condensation has been eliminated. If one measure proves to be ineffective, the next measure is initiated. Once successful, the measures previously performed are reversed step-by-step in reverse order.
Measures against condensation on windscreen:
- Open the defrost flaps further (max. 17.5 %)
- Switch to partially fresh air from air-recirculation/AUC/automatic air-recirculation mode
- Switch from partially fresh air in air-recirculation/AUC/automatic air-recirculation mode to fresh air
- Switch off variable evaporator control
- Raise blower speed (max. 28 %)
- Reduce airflow to footwell (by about 60 %)
- Increase temperature setting (by max. 2.5 °C)
