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.

If your vehicle does not have air conditioning, your
heater controls will look like this.

The knob on the left side of the heating 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.

The middle knob on the control panel regulates the
temperature of the air flowing into your vehicle. Turn
the knob toward the red area for warmer air. Turn the
knob toward the blue area for cooler air.

The right knob changes the heater setting.

VENT: This setting directs air through the

instrument panel vents.

LEVEL: This setting divides airflow between

the heater floor vents and instrument panel vents.

HEAT: This setting directs air through the heater

floor vents.

HEAT/DEFOG: This setting divides airflow

between the heater floor vents and windshield.

DEFROST: This setting directs air through the

windshield defroster vents. This setting is used to
remove fog or ice from the windshield.
