V E N T Use when the outside
temperature is mild, and little heating or
cooling is needed. Air flow is through
the instrument panel outlets. Set the
lower lever to the temperature desired.
B/L (Bi-Level): Use on cool, but sunny
days. This setting brings in the outside
air, but directs it in two ways. The cool
air is directed to the upper portion of
your body through the instrument panel
outlets, but slightly warmer air is directed
through the heater ducts and defroster
vents. At times this temperature difference
may be more apparent than others.
HTR (Heater): This setting brings
heated air through the heater ducts, and
some through the windshield defroster
vents.
DEF (Defrost): This setting directs
most air through the windshield
defroster vents, and some through the
heater ducts.
Defogging Windows
To defog the windshield, slide both
levers to the far right and move the fan
control lever to
