BMW 3: Parked-car ventilation


The car's interior can be cooled or heated before driving off with the parked-car ventilation. Depending on set temperature and ambient temperature, the car's interior is ventilated or possibly heated using the residual engine heat.

General information

The system can be switched on and off directly or via a preset departure time.

The activation time is determined based on the external temperature. The system promptly switches on before the selected departure time.

Functional requirements

  • The vehicle is in idle state or standby state and not in drive-ready state.
  • Battery is sufficiently charged.

    If parked-car ventilation is switched on, the vehicle battery will be discharged. Thus, limit the maximum activation time to save the vehicle battery. The system will be available again after the engine is started or after a short trip.

  • Make sure that the vehicle's date and time are set correctly.
  • Open the vents to allow air to flow out.
