Comfort Controls
This section tells you how to make your air system work
for you.
With these systems, you can control the heating, cooling
and ventilation in your vehicle.
System Controls
If your vehicle does not have air conditioning, your
controls will look like this.
Fan Knob
The knob on the left side of the system 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 regulates the
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. Turn the knob toward the red area for
warmer air. Turn the knob toward the blue area for
cooler air.
