Defogging And Defrosting - GMC Chevrolet SSR 2003 Owner's Manual

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 and side windows. Use the
defog mode to clear the windows of fog or moisture
and warm the passengers. Use the defrost mode
to remove fog or frost from the windshield more quickly.
For best results, clear all snow and ice from the
windshield before defrosting.
/
(Floor/Defog): This mode directs half of the air to
the windshield and the side window outlets and the other
half to the floor outlets. When you select this mode,
the system runs the air-conditioning compressor unless
the outside temperature is at or below freezing.
Recirculation is not available in this mode.

0
(Defrost): This mode directs most of the air to the
windshield, with some air directed to the side window
outlets and the floor outlets. When you select this mode,
the system runs the air-conditioning compressor
unless the outside temperature is at or below freezing.
Recirculation is not available in this mode.

(Maximum Defrost): This mode directs most of
the air to the windshield, with some air directed to
the side window outlets and the floor outlets. The rear
window defogger and heated outside mirrors will turn on,
and the fan speed will be at the highest setting (5).
The temperature will be at the hottest setting also.
Recirculation is not available in this mode.
If this mode was selected when you turn your vehicle
off, the warmest temperature and highest fan speed will
be restored when the vehicle is started, regardless of
the temperature and fan setting.
Do not drive the vehicle until all the windows are clear.
