Preconditioning
Preconditioning of the car before driving reduces wear and energy needs during a journey.
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.
- The ventilation, in a hot climate, cools the passenger compartment to the current outer temperature.
Note
During preconditioning of the passenger compartment, the car works to reach comfort temperature and not the temperature set in the climate control system.
Climate comfort retention
The climate in the car's passenger compartment can be maintained while the car is parked, e.g. if the engine needs to be switched off but the driver or passenger(s) wants to remain in the car and maintain the level of climate comfort.
Starting climate comfort retention is only possible via direct start.
The function utilises several systems in different cases:
- Residual heat from the engine, in a cold climate, heats the passenger compartment to comfort temperature.
- The ventilation, in a hot climate, cools the passenger compartment to the current outer temperature.
Note
Climate comfort retention is switched off when the car is locked from the outside to avoid using residual heat unnecessarily. Use of the function is intended to maintain climate comfort when driver or passengers remain inside the car.
