turned off as desired.
Press one of the buttons listed below to select the
desired air flow. An indicator light will show the current
selection. Pressing the button for the selection in use
will display the inside temperature setting.
UPPER: Use to direct most of the air flow through the
upper vents
in
the instrument panel. Some air will also
flow through the lower outlets.
BI-LEV: Use bi-level on cool, but sunny days. This
setting directs air in two ways. Cool outside air is
directed to the upper portion of your body through the
upper vents in the instrument panel. Warmed air is
directed through the lower vents, with a little air flow
through the windshield and side window vents. At times
this temperature difference may be more apparent than
others.
LOWER: Use to direct most of the air through the
lower vents. Some air
will
flow through the windshield
and side window vents.
DEFOG: Use on cold, humid days with two or more
passengers when the windows fog. The air is directed
through the windshield, side window, and lower vents.

FRONT Use defrost to direct most of the air to
the windshield and side window vents. The air
conditioning may run if the temperature is above 40°F

RECIRC: When RECIRC is selected, the system will
limit the amount of fresh air entering your vehicle. This
is helpful when you are trying to cool the air quickly or
limit odors entering your vehicle. Air flow is directed
through the upper instrument panel vents. This control
does not affect air flow direction. DEFOG and FRONT
will not recirculate.
