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 choose from
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 or counterclockwise to
select one of the following modes:
-(Defog):This mode directs the air to the oor outlets,
windshield and side window outlets. The recirculation
button cannot be selected while in defog mode.
1(Defrost):This mode directs most of the air to the
windshield and the side window outlets, with only a
little air directed to the oor outlets. The air conditioning
compressor may run to dehumidify the air to prevent
window fogging. The recirculation button cannot
be selected while in defrost mode. Do not drive the
vehicle until all the windows are clear.
Rear Window Defogger
The lines you see on the rear window warm the glass.
<(Rear):Press this button to turn the rear window
defogger on or off. The rear window defogger can
only be activated if the tailgate window is fully closed.
The Driver Information Center will display “Tailgate
Glass Down” to indicate that the rear window defogger
has been disabled because the window is not fully
closed. An indicator light in the button will come on to
let you know that the rear window defogger is active.
The rear window defogger will automatically turn
off approximately ten minutes after the button is pressed.
If your vehicle is equipped with heated mirrors, this
button will activate them.
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.
