Defogging and Defrosting
Fog or frost 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. To avoid fogging
windows on rainy and humid days at temperatures
above freezing, turn on the air conditioning
system. Also, it is best to avoid the use of the
recirculation mode, except when maximum
A/C performance is needed or for short times to
avoid exterior odors.
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. When you select either of these
modes, or the floor mode which also helps defog
the windows slightly, the system runs the air
conditioning compressor and cancels recirculation
mode to dry the air; however, the recirculation light
will stay on. For best results, clear all snow and ice
from the windshield before defrosting.
Turn the right knob to select the defog or
defrost mode.
-(Defog): This mode directs half of the air to
the windshield and the side window outlets,
and half to the floor outlets.
0(Defrost): This mode directs most of the air to
the windshield and the side window outlets, with
some air directed to the floor outlets.
