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. You can use either defog or front defrost to clear fog or frost from your windshield.
(Defog): Use this setting
to clear the windows
of fog or moisture. This setting will deliver air
to the floor and windshield outlets.
(Front Defrost): Press
the front defrost button
to clear the windshield and side windows of
frost or fog quickly. The system will automatically
control the fan speed if you select defrost from
AUTO mode. If the outside temperature is
40°F (4°C) or warmer, your air conditioning
compressor will automatically run to help
dehumidify the air and dry the windshield. Do not
drive the vehicle until all the windows are clear.
