Automatic Operation Manual 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.
In cold weather, the system will delay turning on the
fan, to avoid blowing cold air. The length of the delay
depends on the engine coolant temperature an.d the
outside temperature. Pushing the FAN, AIR FLOW or
FRONT buttons will override this delay, turn off the
AUTO setting and change the fan speed.
You may also manually adjust the air delivery or
fan speed.
AIR FLOW: This button is used to change the direction
of the airflow. The airflow choices available are
FLOOR, FLOOR-MID, MID and
WINDSHIELD-FLOOR. If the system is set for AUTO,
pressing the AIR FLOW button will display the current
airflow direction and the comfort setting. Press the AIR
FLOW up or down button again to change the direction
of the airflow.
If the AIR FLOW up button is selected while in the
FRONT defrost mode, the system will direct the air
toward the WINDSHIELD-FLOOR. If the AIR FLOW
down button is selected while in the FRONT defrost
mode, the system will direct the air toward the FLOOR,
and the FRONT defrost mode will cancel. Notice the
arrows in the display.
