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 or frost from the windshield and side
windows. 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.
Turn the left knob to select the defog or
defrost mode.
-(Defog): This mode directs about half of the air
to the windshield and the side window outlets and
half to the floor outlets. When you select this mode
the system runs the air conditioning compressor. To
defog the windows faster, turn the temperature
control knob clockwise to the warmest setting.
0(Defrost): This mode directs most of the air to
the windshield, with some air directed to the
side window outlets and the floor outlets. When
you select this mode the system runs the air
conditioning compressor. To defrost the windows
faster, turn the temperature control knob
clockwise to the warmest setting.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
The rear window defogger will only work when the
ignition is in RUN.
<(Rear): Press the button to turn the rear
window defogger on or off. Be sure to clear as
much snow from the rear window as possible. An
indicator light above the button will come on to
let you know that the rear window defogger
is activated.
The rear window defogger will turn off about
15 minutes after the button is pressed. If turned
on again, the defogger will only run for about
seven minutes before turning off. If the vehicle is
moving faster than 50 mph (80 km/h), the rear
defogger will stay on. The defogger can also be
turned off by pressing the button again or by
turning off the engine.
Notice: Do not use anything sharp on the
inside of the rear window. If you do, you could
cut or damage the warming grid, and the repairs
would not be covered by your warranty. Do not
attach a temporary vehicle license, tape, a decal
or anything similar to the defogger grid.
