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.
Manual Comfort Controls
Fan Knob
The left knob is the fan knob and controls the force of
air you want. Turn the knob clockwise to increase fan
speed or counterclockwise to decrease fan speed. The
fan must be turned on for the air conditioning
compressor to operate.
Temperature Knob
The center knob controls the temperature of the air
coming through the system. Turn it counterclockwise
(toward the blue area) for cooler air. Turn it clockwise
(toward the red area) for warmer air.
Mode Knob
The right knob selects the direction of where the air will
enter the vehicle.
UPPER: This setting directs most of the air through
the instrument panel outlets with a very small amount of
air directed to the lower outlets.
BI-LEVEL: This setting directs air into the
vehicle in two ways. Cooler air is directed toward your
upper body through the instrument panel outlets, while
warmer air is directed through the lower outlets.
