If the car's outer vents are aimed at the side windows then misting can be eliminated.
If the car's outer vents are aimed inwards then, in a hot climate, a comfortable environment is obtained in the passenger compartment.
Opening and closing the air vents
Roll the thumbwheel under the air vent in order to open/close the air flow from the vent.
The longer the white lines on the thumbwheel that are visible, the higher the air flow.
