Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use VENT to direct outside air
through your vehicle. Your vehicle also has the
flow
-
through ventilation system.
Your vehicle’s flow
-
through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the air conditioning
fan is running.
You will find air outlets in the center and on the sides of
your instrument panel.
You can direct the airflow side to side by moving the
sliding levers. The outlet can be tilted up and down also.
To control the amount of airflow through the outlets,
rotate the thumbwheel.
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.
D Keep the air path under the front seats clear of
objects. This helps air circulate throughout
your vehicle.
D To prevent circulation of outside air, press the
recirculation button. This will close all outside vents.
