(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 75 F (24 C)
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.
