Opening, closing and aiming the air vents
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
Turn the rotary knob in the middle of the air vent to open/close the air flow from the vent.
The air flow is at maximum when the marking on the knob is in vertical position.
Move the lever in the middle of the air vent up/down to open/close the air flow from the vent.
The air flow is switched off in the bottom position, while it is constant in other positions.
