remaining air to the floor outlets. A little air is directed
toward the windshield and the side window outlets.

air to the floor outlets.

button cannot be selected in floor mode.
h (Recirculation): Press this button to turn
recirculation mode on or off. When this button is
pressed, an indicator light in the button will also come
on to let you know that it is activated. Recirculation
mode is used to recirculate the air inside of
your vehicle. Use this mode to help prevent outside
odors and/or dust from entering your vehicle or
to help cool the air inside of your vehicle more
quickly. Recirculation mode can be used with vent and
bi-level modes, but it cannot be used with floor,
defog or defrost modes.
If the weather is cold and damp, the system may
cause the windows to fog while using recirculation
mode. If the windows do start to fog, select
defog or defrost mode.
