FAN: Press the up arrow on the FAN control to
increase fan speed and the down arrow to decrease fan
speed. Pressing the arrows cancels the automatic
operation and places the system in manual mode. Press
the AUTO button to return to automatic operation. If
the airflow seems low when the fan is at the highest
setting, the passenger compartment air filter, if
equipped, may need to be replaced. For more
information see Passenger Compartment Air Filter on
page 3-25 and Scheduled Maintenance on page 6-4.
AIR FLOW: This control has several settings to control
the direction of airflow when the system is not in AUTO.
To access the various modes available, continue to press
the AIR FLOW up or down arrows until the desired mode,
listed below, appears in the display.
WINDSHIELD/FLOOR: This setting directs some of the
air to the floor outlets and some to the defroster and
side window outlets. The air-conditioning compressor will
run automatically in this setting unless the outside
temperature is below 40°F (4°C).
MID/FLOOR: This mode directs airflow through both
the floor and the instrument panel outlets. A small
amount of air is directed to the windshield and the side
window outlets.
MID (Instrument Panel): This mode directs air through
the instrument panel outlets.
3-22
FLOOR: This setting sends most of the air through the
outlets near the floor. The rest comes out of the
defroster and side window outlets.
VENT: Press this button to turn the air-conditioning
compressor on or off. The indicator light on the VENT
mode is lit when the compressor is turned off. The
interior brightness control might have to be adjusted to
the highest setting during the day in order to see
the indicator lamp.
VENT does not operate in the FRONT defrost mode.
RECIRC (Recirculation): Press this button to turn this
mode on or off. RECIRC limits the amount of outside
air coming into the vehicle and recirculates most of the
air inside your vehicle. It can be use to prevent
outside air and odors from entering the vehicle or to
quickly heat or cool the air inside the vehicle. When this
button is pressed an indicator light will come on. The
interior brightness control might have to be adjusted to
the highest setting during the day in order to see the
indicator lamp.
This setting is not permitted in FRONT defrost mode
and is only permitted in WINDSHIELD/FLOOR mode if
the compressor is turned on.
On hot days, open the windows to let hot air inside
escape; then close them. This helps to reduce the time
it takes for the vehicle to cool down. It also helps the
system to operate more efficiently.
