use of engine
cooling air to heat the interior
'of the car. After performing
its engine cooling function the
air is channeled through a
blower and on into the car.
Air provided by the engine
blower may also be diverted
prior to passing over the engine to provide cooler air for
temperature modulation or mild weather heating. With
the AIR and HEAT controls in the OFF position, the engine
heat is ducted to the rear of the engine and out through
the thermostatically controlled engine cooling doors.
The heater controls are:
FAN-Controls blower speed. Blower must not be oper-
ated unless either the HEAT or AIR lever is depressed.
AIR-Controls the amount of
moderately
heated air pre-
sented to the heater system
.
HEAT -Controls the amount
of.
hot air
to the system.
DEF.-The DEFROSTER lever diverts the flow of air to the
defroster outlets.
OPERA TION FOR MAXIMUM COMFORT
• MINIMUM HEAT REQUIREMENTS-During spring and
fall in areas where climatic conditions are less severe,
depress the AIR lever
only
as required for your comfort.
• MEDIUM HEAT REQUIREMENTS-Depress the AIR lever
all the way down, then depress the HEAT lever as
required
.
This will control the flow of mixed air (mod-
erately heated and hot air) necessary for temperature
control and provide definite variation of air tempera
-
ture.
• MAXIMUM HEAT REQUIREMENTS-Depress HEAT and
AIR levers to extreme down position. If heat becomes
excessive, pull up HEAT knob to desired position.

NOTE
:
Since"Water vapor and odors may collect when vehicle stands for long periods. keep the HEAT and AI R levers in OFF position for
first few minutes of engine operation. This will reduce the tendency for moisture to condense on w
i
ndshield and will reduce odors
entering passenger compartment. Windshield fogging at start of defroster operation may be corrected by opening
vent'
windows.
Oil spilled on engine shrouding may cause odor in passenger compartment. To avoid discomfort. the cause of any odor should
be traced and any defect promptly corrected.
