Automatic Operation
Press the AUTO button when you want the system to
automatically adjust to changes in the temperature.
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 a display
of 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, fan speed and airflow direction
for a few seconds, and then it will display the
outside temperature.
In cold weather, the system will delay turning the fan on
high, to avoid blowing cold air. The length of the delay
depends on the engine coolant temperature and 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.
Manual Operation
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, the comfort
setting and the fan speed. 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 mid
- position. 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.
