The following occurs when the defroster/windshield heating functions have been activated:
- Blower speed increases automatically and the air conditioning will switch on (if not already on and if the passenger compartment blower is not turned off) to dehumidify the air in the passenger compartment. Air conditioning can be switched off by pressing the AC button.
- Recirculation will not function while defrost is engaged.
The climate system will return to its previous settings when the defroster/windshield heating function is switched off.
