Fan Knob
The knob on the left side of the control panel regulates
the fan speed. The knob has four speed positions. To
increase airflow, turn the knob toward HI. To decrease
airflow, turn it toward LO. To turn the fan off, turn the
mode knob on the far right to OFF.
Temperature Knob
The middle knob on the control panel lets you select
the temperature of the air flowing into the passenger
compartment of your vehicle. This knob will allow you
to adjust the air temperature independently of the
function knob setting. Turn the knob toward the red
area for warmer air. Turn the knob toward the blue
area for cooler air.
Mode Knob
The right knob on the control panel changes the
heater/air conditioning setting.
MAX A/C (Maximum Air Conditioning): Turn the
right knob to MAX A/C for maximum cooling. This
setting puts the system in the recirculation mode and
helps to maximize your air conditioner’s performance
and your vehicle’s fuel economy. This setting also cools
the air the fastest. After the vehicle’s interior reaches a
comfortable temperature, turn the knob clockwise to
place the air conditioning system in the A/C mode.
A/C (Air Conditioning): This setting is used for normal
cooling on hot days. It cools outside air and directs it
through the instrument panel outlets.
(Bi - Level Air Conditioning): This setting divides
airflow between the floor vents and instrument panel
vents. The air conditioning compressor will cycle
continuously in this setting as long as the outside air
temperature is warm enough to activate the compressor.
(Vent): This setting directs air through the
instrument panel vents.
(Floor): This setting directs air through the
floor vents.
(Floor/Defrost): This setting divides airflow
between the floor vents and the windshield. In the
blended position, the air conditioning compressor is
automatically activated to dehumidify the air.
(Defrost): This setting directs air through the
windshield defroster vents. It is useful when you have
fog or ice on the windshield.
