Temperature Buttons
Maintain the temperature inside the vehicle by using the
red and blue arrows located below the digital display. If
you want a warmer comfort level, push the red arrow. If
you want a cooler comfort level, push the blue arrow.
Your selected comfort setting will be shown on the
digital display for five seconds, then the outside
temperature will be displayed.
Manual Operation
Use the left and right mode knobs, along with the
buttons on your climate control system to operate the
system manually.
OFF: Turning the left mode knob to OFF will cause
the fan to turn off and the airflow to be directed through
the floor ducts. The system will work to maintain the
previously chosen temperature setting. The display will
show the outside temperature when the system is set
to OFF.
(Panel): This setting directs the airflow through
the instrument panel outlets.
(Bi-Level): This setting directs the airflow
through both the instrument panel outlets and the floor
ducts. There is also a small amount of air directed to the
front defroster and the side window defrosters.
(Floor): This setting directs most of the airflow
to the floor ducts. There is also some airflow directed
to the side window defrosters and a small amount of
airflow directed to the front defroster.
(Defogger): This setting directs the majority
of the airflow to the floor ducts and the front defroster,
with a small amount of airflow to the side window
defrosters. This can be useful in helping to remove
moisture from the inside of the windshield when the
outside temperature is cold or the humidity is high. The
air conditioning indicator light will come on to show the
air compressor is working to dehumidify the air.
(Defroster): This setting directs the majority of the
airflow to the windshield with some airflow to the side
window defrosters and the floor ducts. To increase the
fan speed, turn the right mode knob clockwise.
Even though air conditioning is not selected, in defrost
mode the air conditioning compressor will run
automatically at temperatures over approximately 40
F
(4
C) to improve windshield clearing performance. This
dehumidifies the air to help dry the windshield. Even
though the compressor may be running, the air
conditioning indicator light will not come on in defrost
unless you select air conditioning.

(Air Conditioning): Press this button to turn
the air conditioning compressor on and off. The air
conditioning indicator light will illuminate. In the
automatic mode, the air conditioning compressor will
only operate when the system determines it is needed.
(Recirculation): Press this button to limit the
amount of outside air entering your vehicle. This is
helpful when you are trying to cool the interior of the
vehicle quickly or limit the amount of outside air
entering your vehicle for some other reason. The
recirculation button may be selected and the mode knobs
may be adjusted at the same time. The system will
remain in recirculation until the ignition is turned off,
then the system will return to the previously selected
mode. Recirculation may be selected in all airflow
modes except defrost.
When the weather is cool or damp, operating in
recirculation for extended periods of time may cause
fogging of the vehicle's windows. To clear the fog,
switch back to outside air by turning off recirculation,
then select either defogger or defrost mode and increase
the fan speed. To avoid refogging of the windows,
minimize your use of recirculation under these
conditions and turn the air conditioning on to help
dehumidify the air.Automatic Operation
Press the left and right mode knobs for the system
to automatically maintain the air temperature, airflow
direction and the fan speed. They will be controlled based
on the selected temperature setting, the temperature inside
the vehicle, the outside temperature and the sun load.
Fan speed will vary as the system reaches and maintains
the comfort setting you have selected.

Press the left and right mode knobs to turn on
the lights under the knobs, indicating that the
system is being controlled automatically. Your
current temperature setting will be shown in the
digital display.

Then adjust the temperature level using the red
and blue arrows located below the climate control
display until you reach a setting of 75F (24C)
on the display. Give the vehicle about 30 minutes to
stabilize and then readjust the temperature setting if
necessary. The display will show the temperature
setting for five seconds and then it will show the
outside temperature.
