3-3
Mode Knob
The right knob has several settings to control the
direction of airflow. For each setting, select the
temperature that is comfortable.
(Maximum): For maximum cooling use this
setting to recirculate much of the air inside your vehicle
and send it through the instrument panel outlets. The air
conditioning compressor will run automatically in this
setting when it is needed to help cool the air in the
vehicle. The indicator light will turn on in this mode.
Operation in this mode during periods of high humidity
and cool outside temperatures may result in increased
window fogging. If window fogging is experienced,
select the defrost mode.
(Vent): This setting brings in outside air and directs
it through the instrument panel outlets.
(Bi - Level): This setting brings in outside air and
directs it two ways. Some air is directed through the
instrument panel outlets. Most of the air is directed
through the floor ducts and a little to the defrost and
side window vents.
(Floor): This setting sends most of the air
through the ducts near the floor. The rest comes out of
the defroster and side window vents.
(Defog): This setting allows half of the air to
go to the floor ducts and half to the defroster and side
window vents.
(Defrost): This setting directs most of the air
through the defroster and side window vents. Some of
the air goes to the floor ducts. The air conditioning
compressor will run automatically in this setting when it
is needed to help dry the air in the vehicle. The A/C
indicator light will also be on in the setting.
Air Conditioning Compressor Button
Press the A/C button to operate the air conditioner
compressor. The indicator light above the button will
glow when the air conditioning compressor is running.
You don’t have to press the button to run the compressor
in max or defrost.
Running the compressor will help reduce vehicle
interior fogging.
