Automatic Operation 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 and the comfort setting. Press the AIR
FLOW up or down button again to change the direction
of the airflow.
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 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.
If the AIR FLOW up button is selected while
in
the
FRONT defrost mode, the system will direct the air
toward the windshield and the 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.
OFF:
If the passenger comfort control is turned on,
it
can be turned off by pressing the OFF button once.
Pressing the OFF button a second time
will
turn off the
main system. Turning off the main system causes the fan
to turn off and the airflow to be directed toward the
floor.
The
system will still try to keep the interior of the
vehicle at the previous chosen comfort setting. The
outside temperature will show on the display when the
system is
OFF.
