Specifications
Cadillac Automatic Heating Controls
The controls for the
heater,
which may be
either the
Cadillac
Automatic Heating
System, or the
Cadillac
Ventilating-De-
frosting
Heater, are located on the left-
hand side of the
grille
in the
center
of the
instrument panel.
The
Cadillac
Automatic Heating System works as simply as thermo-
statically
controlled heating in your home. This system has two con-
trol
levers. The left-hand lever, marked "Heat," is the thermostatic
control.
In its uppermost position the
heaters
are off. As it is moved
downward, the
heat
delivery increases.
Maximum
or
"Hi"
heat
is
attained when the lever is all the way down. By placing the lever in
the position desired for your comfort, the system
operates
auto-
matically
on and off when the ignition switch is on. Temperature
selected remains
constant.
NOTE:
Do not turn
heaters
on
until
engine coolant is at operating
temperature.
This
will
prevent
cir-
culation
of
cold
air.
The right-hand lever (marked "Defr") controls both the fresh air
supply to the defroster and the defroster fan. When the lever is in the
"Off"
position, the fresh air intake valve is closed and the fan is off.
When
the lever is moved to the vent position, the fresh air valve is
opened but the fan is kept
"Off."
This position is recommended for
ventilation.
In the positions just above and below
"Fog"
the defroster
is
operating, first at low speed, then at high speed for normal defrost-
ing.
At the "Ice" position, the air intake valves are closed and the
defroster is on at high speed, providing maximum
heat
to prevent ice
formation
on the windshield.
Ventilating-Defrosting Heater Controls
The
Cadillac
Ventilating-Defrosting Heater also has two controls,
the
heat
control at the right marked "Heat," and the fresh air control
at the left marked
"Air."
The heal control is "Off" in the central position.
Moving
the lever
upward provides direct circulated
heat
at high, medium, or low
velocity.
Once your car has been brought to a comfortable tempera-
8
ture,
the
heater
motor can be turned off and the fresh air valve
opened to maintain the
temperature
in
mild
winter
weather.
Mov-
ing
the
"Heal"
lever into the lower or "Defroster"
range
reverses
the
air
current direction from the
heater
fan, thereby providing in-
direct heating with maximum defrosting in
three
speeds,
when the
fresh air lever is in the "Off" position. For normal indirect heating,
put the fresh air lever in the "On"
po-ilion.
The fresh air lever should normally be carried in the "On" position.
It can be moved to the "Off" position when maximum defrosting is
required to melt ice from the windshield.
