For mild outside temperatures when little heating or
cooling is needed, use outside air to direct outside air
through your vehicle. Air will flow through the
instrument panel outlets.

Your vehicle’s ventilation system supplies outside air to
the inside of your vehicle when it is moving. With the
side windows closed, air will flow into the front air 
inlet grilles, through the vehicle, and out the air 
exhaust valves.

Outside air will also enter the vehicle when the heater or
the air conditioning fan is running, unless you have the
recirculation button pushed in. For more information on
the recirculation button, see “Air Conditioning” earlier
in this section.

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, turn the

fan knob all the way to the right for a few moments
before driving. 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.

D The use of non

may adversely affect the performance of the heating
and air conditioning system.
