and little heating or cooling is needed. Airflow is
through the instrument panel outlets. Set the center
control knob to the temperature desired.

BI-LEVEL: Use on cool, but sunny days. This
setting brings in the outside air, but directs it in two
ways. Cooler air is directed to the upper portion of your
body through the instrument panel outlets; slightly
warmer air is directed through the heater ducts and
defroster vents. At times, this temperature difference
may be more apparent than others.
