outside air through the comfort control system.
For the quickest results, move the air intake lever to
RECIRCULATE and the airflow knob to FLOOR.
Turn the temperature knob clockwise for warmer air
and turn the fan knob toward HI. You should switch
to CIRCULATE once in a while to avoid stale air and
cloudy windows. To prevent cold air from blowing in,
you may shut off the outer dash vents by using the
thumbwheels.

Move the air intake lever to CIRCULATE and turn the
airflow knob to BI-LEVEL. Turn the temperature knob
to the white area and the fan knob toward HI.
Ventilation
For mild outside temperatures, when very little heating
is required, you can still direct outside air through your
vehicle.
Move the air intake lever to CIRCULATE and turn the
airflow knob to VENT. Turn the temperature knob to a
comfortable setting and the fan knob toward HI.
