Defogging and Defrosting Fog on the inside of the 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. 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. Turn the right knob clockwise to select the defog or defrost mode. This mode directs air equally to the windshield and the floor outlets. When you select this mode, the system turns off recirculation and runs the air conditioning compressor unless the outside temperature is below 40°F (4°C). The recirculation mode cannot be selected while in the defog mode. 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 from the rear window.

Defogging and Defrosting
Fog on the inside of the 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. 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.
Turn the right knob clockwise to select the defog or
defrost mode.
-
(Defog):
This mode directs air equally to the
windshield and the floor outlets. When you select this
mode, the system turns off recirculation and runs the air
conditioning compressor unless the outside temperature
is below 40°F (4°C). The recirculation mode cannot
be selected while in the defog mode.
Do not drive the vehicle until all the windows are clear.
0
(Defrost):
This mode directs half of the air to
the windshield and side window vents and half to the
floor vents. In this mode, the system will automatically
force outside air into your vehicle. The recirculation
mode cannot be selected while in the defog mode.
The air conditioning compressor will run automatically in
this setting, unless the outside temperature is below
40°F (4°C).
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 from the rear window.
<
:
The rear window defogger will turn off
approximately 20 minutes after the button is pressed. If
turned on again, the defogger will run for the same
amount of time. The defogger can also be turned off by
pressing the button again or by turning off the engine.
Do not drive the vehicle until all the windows are clear.
If your vehicle has heated outside rearview mirrors,
the mirrors will heat to help clear fog or frost from the
surface of the mirror when the rear window defog button
is pressed.
Notice:
Don’t use anything sharp on the inside of
the rear window. If you do, you could cut or damage
the warming grid, and the repairs wouldn’t be
covered by your warranty. Do not attach a temporary
vehicle license, tape, a decal or anything similar
to the defogger grid.
