Parked-car ventilation
The concept
The parked-car ventilation ventilates the vehicle
interior and lowers its temperature, if necessary.
The system can be switched on and off at any
external temperature, either directly or by using
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 parked-car vent."
The symbol on the automatic climate control
flashes if the system is switched on.
