Temperature Buttons
Maintain the temperature inside the vehicle by using the
red and blue arrows located below the digital display. If
you want a warmer comfort level, push the red arrow. If
you want a cooler comfort level, push the blue arrow.
Your selected comfort setting will be shown on the
digital display for five seconds, then the outside
temperature will be displayed.
Manual Operation
Use the left and right mode knobs, along with the
buttons on your climate control system to operate the
system manually.
OFF: Turning the left mode knob to OFF will cause
the fan to turn off and the airflow to be directed through
the floor ducts. The system will work to maintain the
previously chosen temperature setting. The display will
show the outside temperature when the system is set
to OFF.
(Panel): This setting directs the airflow through
the instrument panel outlets.
(Bi-Level): This setting directs the airflow
through both the instrument panel outlets and the floor
ducts. There is also a small amount of air directed to the
front defroster and the side window defrosters.
(Floor): This setting directs most of the airflow
to the floor ducts. There is also some airflow directed
to the side window defrosters and a small amount of
airflow directed to the front defroster.
(Defogger): This setting directs the majority
of the airflow to the floor ducts and the front defroster,
with a small amount of airflow to the side window
defrosters. This can be useful in helping to remove
moisture from the inside of the windshield when the
outside temperature is cold or the humidity is high. The
air conditioning indicator light will come on to show the
air compressor is working to dehumidify the air.
(Defroster): This setting directs the majority of the
airflow to the windshield with some airflow to the side
window defrosters and the floor ducts. To increase the
fan speed, turn the right mode knob clockwise.
Even though air conditioning is not selected, in defrost
mode the air conditioning compressor will run
automatically at temperatures over approximately 40 F
(4 C) to improve windshield clearing performance. This
dehumidifies the air to help dry the windshield. Even
though the compressor may be running, the air
conditioning indicator light will not come on in defrost
unless you select air conditioning.
