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 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.

(Mode): Press this button until defog appears
on the display.
-
(Defog): This mode directs the air between the
windshield, floor outlets and side windows. When you
select this mode, the system turns off recirculation
and runs the air-conditioning compressor unless
the outside temperature is at or below freezing. The
recirculation mode is cancelled when you enter defog
mode. If you select recirculation while in defog mode,
it will be cancelled after 10 minutes.
If you have fogging on the side windows, turn the
thumbwheel on the outboard outlets to the side window
defog position. See
Outlet Adjustment on page 3-32
for more information.
0
(Defrost): Pressing defrost directs most of the
air to the windshield, with some air directed to the side
windows. In this mode, the system will automatically
turn off recirculation and run the air-conditioning
compressor, unless the outside temperature is at or
below freezing. Recirculation cannot be selected while
in the defrost mode.
This mode may also cause the fan speed and air
temperature to increase.
If you have fogging on the side windows, turn the
thumbwheel on the outboard outlets to the side window
defog position. See
Outlet Adjustment on page 3-32
for more information. Do not drive the vehicle until all the
windows are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
ignition is in ON.
=
(Rear Window Defogger): Press this button to
turn the rear window defogger on or off. Be sure to
clear as much snow from the rear window as possible.
