DEFROST: Press this button to quickly remove
fog or frost from the windshield (the blower works in
-
high
speed). This setting sends most of the airflow to
the windshield with only a small amount to the
floor outlets.
FAN SPEEDS: Press the driver's side
TEMP/AUTO knob to set the fan speed for AUTO. At
this setting, the fan speed is automatically controlled. If
it is cold outside, the blower may not run in the
maximum high fan speed right away. The system checks
the temperature of the engine coolant to assure it is
warm enough to provide heat. When the engine coolant
is warm, the controller allows the fan to gradually
increase to a higher speed. This prevents cold air from
blowing into the passenger compartment. If you want
the blower fan at a high speed, press the up arrow button
until you reach the highest position of the display. If you
want the blower fan at a low speed, press the down
arrow button until the lowest position is displayed.
ON/OFF: Press this button to turn the system off. Press
this button again to turn the system back on. Turning the
climate control system on in this way will recall all
previous manually set mode settings. If the system is
turned on by pushing the driver's TEMP/AUTO knob for
automatic operation, all of the previous manually set mode
settings will be changed back to the fully automatic mode.
AC: Press this button to turn the air conditioning on and
off. The system will cool and dehumidify the air inside
the vehicle. In the automatic operation mode, the display
will show AC OFF when the air conditioning has been
turned off.
RECIRCULATION: Press this button to limit the
amount of fresh air entering your vehicle. This is helpful
to limit odors entering your vehicle. In the automatic
operation mode, the system will use recirculation as
necessary to cool the air. Pressing the recirculation
button will change the operation to a manual mode and
the air will recirculate non
to turn off the recirculation feature.
If you notice the windows fogging, press the
recirculation button to exit the recirculation mode.
