Preconditioning is a climate function which, if possible, attempts to reach comfort temperature in the passenger compartment before departure.

Preconditioning can use direct start or be set via the timer.

The function utilises several systems in different cases:
  • In a cold climate, the parking heater warms up the passenger compartment to a comfortable temperature.
  • The air conditioning, in a hot climate, cools the passenger compartment to the comfort temperature.
  • Activation of heated steering wheel* and heated seats* for driver and passenger can be selected.
  • Heated windscreen, rear window and door mirrors are automatically activated as required.

During preconditioning in a hot climate, condensation from the air conditioning may drip under the car. This is normal.


Preconditioning is available only when the car is connected to an electrical socket1. A charging station which is not always active, e.g. on account of a timer, may cause preconditioning to malfunction.

If the car is not connected to an electrical socket, it is still possible to cool the passenger compartment briefly in a warm climate by starting preconditioning directly.


During preconditioning of the passenger compartment, the car works to reach comfort temperature and not the temperature set in the climate control system.
