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.
  • When it is warm, the climate control ventilates the passenger compartment by blowing in air from outside the car.


In temperatures immediately below comfort temperature, neither ventilation nor heating is activated and no preconditioning is started.


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


Precleaning* starts automatically when preconditioning is completed.
