Comfort Controls
This section tells you how to make your air system work
for you. Your comfort control system uses
ozone
-friendly R-134a refrigerant.
With these systems, you can control the heating, cooling
and ventilation in your vehicle. Your vehicle also has a
flow
-through ventilation system described later in
this section.

Fan Knob
The left knob is the fan knob and selects the force of air
you want. Turn the knob clockwise to increase fan speed
and counterclockwise to decrease fan speed. The fan will
always run unless the right control knob is turned to OFF.
The fan must be on to run the air conditioning compressor.
Temperature Knob
The center control regulates the temperature of the air
coming through the system. Turn it toward the blue area
for cooler air. Turn it toward the red area for warmer air.
Mode Knob
The right control has settings for air conditioning and
non
-air conditioning modes. The mode control allows
you to choose the direction of air delivery.
MAX: This setting provides maximum cooling with the
least amount of work. MAX recirculates much of the air
inside your vehicle so it cools quickly. The air is
directed through the instrument panel outlets.
