Ventilation System
Change the direction
of the airflow by
adjusting 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 compressor is running and the
outside air button is pressed
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 (if equipped) may need
to be replaced. See “Maintenance Schedule” and
“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 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.
