Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is
used properly. There are two modes to clear fog or frost
from your windshield. Use the floor/defog mode to
clear the windows of fog or moisture and warm
the passengers. Use defrost to remove fog or frost from
the windshield more quickly.
- (Floor/Defog): Press this button to direct the air
between the windshield, floor outlets and side windows.
When you select this mode, the system turns
recirculation off and runs the air conditioning compressor
unless the outside temperature is near or below
freezing. Pressing the recirculation button will have no
effect other than turning on the indicator light while
in floor/defog mode.
1 (Defrost): Press this button to direct most of the
air to the windshield, with some air directed to the
side windows. In this mode, the system will automatically
turn off the recirculation and run the air conditioning
compressor, unless the outside temperature is near or
below freezing. Pressing the recirculation button will
have no effect other than turning on the indicator light
while in defrost mode.
Do not drive the vehicle until all windows are clear.
Sensors
The solar sensor on the vehicle monitors the solar heat
and the air inside of the vehicle. This information is
used to maintain the selected temperature by initiating
needed adjustments to the temperature, the fan
speed, and the air delivery system. The system may
also supply cooler air to the side of the vehicle facing the
sun. The recirculation mode will also be activated, as
necessary. Do not cover the solar sensor located in the
center of the instrument panel, near the windshield,
or the system will not work properly.
