Parked-car ventilation
The concept
The parked-car ventilation ventilates the vehi‐
cle interior and lowers its temperature, if nec‐
essary.
The system can be switched on and off at any
external temperature, either directly or by us‐
ing two preset switch-on times. It remains
switched on for 30 minutes.
Open the vents to allow air to flow out.
Operation can be performed via iDrive.
Switching on/off directly
1. "Settings"
2. "Climate"
3. "Activate comf. ventilation"
The symbol on the automatic climate con‐
trol flashes if the system is switched on.
