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.

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.
