Ventilation System
Adjust the direction
of airflow by moving
the vents.
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.
If the airflow seems very low when the fan is adjusted to
the highest setting regardless of the mode setting, your
passenger compartment air filter may need to be
replaced. See “Maintenance Schedule” or “Passenger
Compartment Air Filter” in the Index.
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 or button to FLOOR and the fan to the
highest speed for a few seconds 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 to circulate throughout
your vehicle.
