Ventilation System

cooling is needed, use VENT to direct outside air
through your vehicle. Your vehicle also has the
-
flow through ventilation system.

Ventilation Tips
D
Keep the hood and front air inlet free of ice, snow or
any other obstruction, such as leaves. The heater and
defroster will work far better, reducing the chance of
fogging the inside of your windows.
D
When you enter a vehicle in cold weather, adjust the
mode knob to FLOOR and the fan to the highest
speed for a few moments before driving off. This
helps clear the intake ducts of snow and moisture
and reduces the chance of fogging the inside of
your windows.
