Opening, closing and aiming the air
vents
Some air vents in the passenger compartment
can be opened, closed and aimed individually.
If the car's outer vents are aimed at the side win-
dows 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.
The illustration is schematic - nozzle design varies depending on location.
