FAN: The left knob selects the force of air you want.
TEMPERATURE: The center knob changes the
temperature of the air coming through the system. Turn
this knob toward red (clockwise) for warmer air. Turn it
toward blue (counterclockwise) for cooler air.
MODE: The right knob has several settings to control
the direction of air flow. For each setting, set the
temperature to a comfortable setting. When the right
control knob is turned to OFF, the fan and the heating
and cooling system will be off.
B/L:-This setting allows the outside
air
to flow through
your
Buick in two ways. Cooler
air
is directed to the
u p e r portion of-your body through the vent outlets.
Slightly warmer
air
is directed through the heater ducts
and defroster outlets.
VENT: Using vent will allow outside air to flow
through the instrument panel outlets.
HTR: This setting sends most of the air through the
heater ducts. Adjust the temperature control to a warm
setting. If you have the engine coolant heater, you can
use it in cold weather (+20°F/-8
O
C or lower) to heat
your vehicle's passenger area quicker. The engine
coolant heater warms the engine coolant which will
ultimately warm the passenger area more efficiently.
(See "Engine Coolant Heater" in the Index.)
BLEND: This setting divides the air flow equally
between the heater and the defroster outlets.
DEFROST This setting operates the defroster.
Most of the air comes out near the windshield. Use
DEFROST when you get fog or ice on the windshield.
