Activating and deactivating max defroster
Max defroster is used to quickly remove mist and ice from windows.
Max defroster deactivates auto-regulation of the climate and air recirculation, activates air conditioning and changes the fan level to 5 and the temperature to High.
Note
Changing the fan level to 5 increases the noise level.
When max defroster is deactivated, the climate control system returns to the previous settings.
