Preconditioning can use direct start or be set via the timer.
The function utilises several systems in different cases:
- The parking heater*, in a cold climate, warms up both the passenger compartment and the engine.
- When it is warm, the ventilation cools the passenger compartment by blowing in air from outside the car.
During preconditioning of the passenger compartment, the car works to reach comfort temperature and not the temperature set in the climate control system.
