Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
or 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 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.
Select one of these available modes from the
right knob.
