Downloaded from www.Manualslib.com manuals search engine 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 van. Your vehicle also
has a flow-through ventilation system described later
in this section.
Heater Controls
If your vehicle does not have air conditioning, your
heater controls will look like this.
Fan Knob
The left knob of the heating system control panel
controls the fan speed. The knob has four speed
positions. To increase airflow, move the knob toward
HI. To decrease airflow, move it toward LO. To turn the
fan off, move the mode knob on the far right to OFF.
Temperature Knob
The middle knob panel lets you select the relative
temperature of the air flowing into the passenger area
of your vehicle. This knob will allow
you to adjust the
relative air temperature independently of the function
knob setting. Move the knob clockwise toward the red
area for warmer air. Move the knob counter clockwise
toward the
blue area for cooler air.
