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 your 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 right knob to select the defog or defrost mode.
- (Defog): This mode directs approximately half of the
air to the windshield and the side window outlets and half
to the floor outlets. When this mode is selected the
system runs the air conditioning compressor. To defog
the windows faster, turn the temperature control knob
clockwise to the warmest setting.
Recirculation mode is not available in defog mode.
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 this mode is selected
the system runs the air conditioning compressor. To
defrost the windows faster, turn the temperature control
knob clockwise to the warmest setting.
Recirculation mode is not available in defog mode.
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 ON/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 below
the symbol comes on to show that the rear window
defogger is activated.
The rear window defogger turns off approximately
15 minutes after the button is pressed. If turned on
again, the defogger only runs for approximately seven
minutes before turning off. If turned on again, the
defogger will only run for approximately seven minutes
before turning off.
If the vehicle speed is greater than 50 mph (80 km/h)
and the rear defogger is active, it remains on as long as
the speed is greater than 50 mph (80 km/h). The
defogger can also be turned off by pressing the button
again or by turning off the engine.
