The concept
The parked-car ventilation blows air into the passenger compartment to lower interior temperatures.
The system can be switched on and off at any external temperature, either directly or by using a preset switch-on time. It remains switched on for 30 minutes.
Since the system uses a substantial amount of electrical current, refrain from activating it twice in succession without allowing the battery to be recharged in normal operation between use.
Open the vents to allow air to flow out.
They can be operated via iDrive.
