<
(Maximum Air Conditioning): Turn the right
knob to this setting for maximum cooling. This
setting puts the system in recirculation mode and
helps to maximize your air conditioner's
performance and your vehicle's fuel economy.
This setting also cools the air the fastest.
Y
(Air Conditioning): This setting is used for
normal cooling on hot days. It cools outside air and
directs it through the instrument panel vents.
)
(Bi-Level Air Conditioning): This setting
divides airflow between the floor vents and
instrument panel vents. The air conditioning
compressor will cycle continuously in this setting
as long as the outside temperature is warm
enough to activate the compressor.
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 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 mode knob on the right of the climate
control panel to select the defog or defrost mode.
-
(Defog): With this setting, the outside air
comes out of both the floor and defroster outlets.
Adjust the temperature knob for warmer or
cooler air. The air conditioning compressor may
operate in this setting to dehumidify the air.
0
(Defrost): This setting operates the defroster.
Most of the air comes out near the windshield,
with some going to the floor outlets and front side
windows. The air conditioning compressor may
operate in this setting to dehumidify the air.
The defog setting is useful for cold weather with a
large number of passengers or very humid
conditions to help keep the windshield clear. Use
defrost to remove fog or ice from the windshield
quickly in extremely cold conditions. The
temperature knob should be in the red area and
the fan control toward high. Do not drive the
vehicle until all the windows are clear.
