BI-LEV
(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.
HEAT
(Heater):
This setting directs
air through the heater ducts, and some
through the windshield defroster vents.
Set
the center control for the desired
temperature.
If you
have the optional engine coolant
heater
and use it during cold weather,
0°F
(-18°C)
or lower, your heating
system
will more quickly
provide heat
because the engine coolant
is
already
warmed. See the
Index
under
Engine
Coolant Heater.
DEFOG:
This setting divides air flow
equally between the heater ducts
and
the windshield defroster vents.
DEF
(Defrost):
This setting
directs most air through the windshield
defroster vents,
and some through
the
heater ducts.
Defogging
Windows

control
knobs

the
f a r
right.
