Sun and temperature sensors automatically adjust the air
temperature, the airflow direction and the fan speed to
maintain your comfort setting. The system may supply
cooler air to the side of the vehicle toward the sun.
Be careful not to put anything over the sensor on top
of the dash.
Temperature Button
To adjust the comfort level you want maintained inside
the vehicle, push the TEMP button. If you want a
warmer comfort level, push the up arrow. If you want
a cooler comfort level, push the down arrow. Your
comfort setting is shown in the display. The display
will then return to the outside temperature.

The speed of the blower fan is controlled automatically
if you have the system set for AUTO. Pressing the
FAN button will display and hold the current blower
fan setting.
If you want the blower fan to run at a lower speed, push
the bottom of the FAN button. The fan speed will

Automatic Operation
Press the AUTO button when you want the system to
automatically adjust to changes in the temperature inside
the vehicle, the outside temperature and the sun load on
the vehicle. When the system is set for automatic
operation, air will come from the floor, middle or
windshield outlets depending on the temperature inside
the vehicle, the outside temperature and sun load. Fan
speed will vary as the system gets to and maintains the
comfort setting you have selected through the use of the
TEMP button.
To find your comfort setting, start with the system in
AUTO mode and the TEMP button adjusted to 75 _ F
(24 _ C), give the vehicle about 20 minutes to stabilize,
and adjust your comfort setting if necessary, by using
the TEMP button. The display will show the comfort
setting for a few seconds and then it will display the
outside temperature. If you want to see your current
automatic fan speed, airflow direction and comfort
setting, press the AUTO button.
