defog or defrost modes. An indicator on the button will
light up, flash three times and turn off when recirculation
is selected in these modes. The air-conditioning
compressor will also come on when this mode is
activated. While in recirculation mode the windows may
fog when the weather is cold and damp. To clear the fog,
select either the blend or defrost mode and increase
fan speed.
Temperature Control
Driver’s Side: The lever on the left side of the climate
control panel is used to raise or lower the temperature on
the driver’s side of the vehicle. This lever also adjusts the
temperature to the center console outlets (if equipped).
Passenger’s Side: The lever on the right side of the
climate control panel is used to raise or lower the
temperature on the passenger’s side of the vehicle.
#(Air Conditioning): Press this button to turn the
air-conditioning system on or off. When the button is
pressed, an indicator light will come on and the system
will begin to cool and dehumidify the air inside of your
vehicle. You may notice a slight change in engine
performance when the air conditioning compressor shuts
off and turns on again. This is normal.
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 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 to select one of the following modes:
-(Defog): This mode directs the air to the floor outlets,
windshield and the side window vents. The air
conditioning compressor will run automatically to
dehumidify the air to prevent window fogging. The
recirculation mode cannot be selected while in the
defog mode.
1(Defrost): This mode directs most of the air to the
windshield and the side window vents, with only a
little air directed to the floor vents. The air conditioning
compressor will run automatically to dehumidify the
air to prevent window fogging. The recirculation mode
cannot be selected while in defrost mode.
Do not drive the vehicle until all the windows are clear.
