warn
of an overheated engine. With
the ignition switch in the
5T AR T
position, the red TEMP indicator
will light to let you know that it is
operating properly. When
the engine
is started , the
red light will go out immediately,
It will light up at no other time
unless for some reason the engine
.
reaches a dangerously high oper,
atingtemperature. If the light
comes on during
extreme driving
conditions, such
as an extended
idle, turn
off the air conditioner (if
used }.and run the engine slightly
faster than
idle. speed with the
transmission in neutral gear .
If the
light does not go
off within a short
period of time
(F2 minutes), then
tum the engine off until the cause
of the.
overheating is corrected;

Brake System Warning
Light
.
The service .. brake system is a
dual system designed
so that. one
part will provide some braking
2-12
action in the event of loss of hy'
draulic pressure in the other part of
the system.
If the ,warning light
labeled
"BRAKE," located in the
speedometer face, comes on .and
stays on when the ignition
is on and
'after · the brakes have been firmly
applied, it may indicate that
there
is a malfunction in one part of the
brake system.

sys­
tem is continuous low:speed opera­
tion of the heater and air condi­

ignition switch is.on. With
the side windows closed,
out side air will

clear of obstructions (leaves,
ice, snow, etc.).
• When heating or air condition-

The following sections of this
manual provide additional operat-
. ing tips for obtaining maximum
heating and
cooling comfort. (See

Comfortron Air Conditioning adds
the convenience of completely
automatic control. to the combined
heating and cooling functions of
the Four-Season system,
automat­
ically maintaining selected inside
temperature regardless of season or
outside weather conditions.
NOTE: In cool weather, the blower
will not start until engine is warmed
up . (Control lever in
"OFF" or
"AUTO" position.)
During warm weather, cooled,
dehumidified air enters the car
through the upper outlets. During
cold weather, heated airflow will
enter the car through the floor
dis­
tributor duct.
Control Panel
The control panel has a tempera­
ture dial and a single control lever.
Temperature Dial
This dial may be set once to the
desired temperature , much
as your
home thermostat, and normally
need not be adjusted thereafter.

ture is reached. Further movement
of the temperature dial will not
de­
crease the time needed to bring the
car to this temperature . However,
since individual comfort
require­
ments vary considerably, you may
wish to vary the dial setting slightly
to compensate for warmer
or cooler
weather.
Control .Lever
In the OFF position, the system
operates on low blower with air
dis­
charged into vehicle through the
heater outlet.
It is not necessary to
turn the system to
OFF when leav­
ing the car. It will then operate
automatically whenever the car is
started.

to moderate weather when refriger­
ation is not required.
During warm weather the system
will
go into operation almost im­
mediately, but cold weather opera­
tion will be delayed until the en­
gine warms up enough to supply
heat
to the system. The tempera- .
ture and blower speed are auto­
matically controlled with the
excep­
tion that the AIC compressor will
not operate. In cold weather,
im­
mediate blower operation can be
obtained in the
DEF position.
Normal Operation-Set the lever
to
AUTO for completely automatic
in-car temperature control. This
setting allows the system
to utilize
various blower: speeds , resulting in
low to moderate airflow.
Placing the lever in the Lo posi­
tion is the same as AUTO setting
except the blower wi\l remain at
low speed.
When greater airflow
is desired or
in severe weather extremes, . set
the lever to HI. The system , still
under automatic
·control, will now
make use of high blower speed
only, resulting in high airflow for
rapid cool
dOwn or heating .
BI-Level Operation
On cool but sunny days . the
Comfortron system
will provide
warm air to the floor and cooler air
out of the upper outlets thus
pro­
viding a warm floot without 'exces­
sive rise in breath level tempera­
ture. Under extremely bright sun
conditions, the system may shift
into bi-level operation at relatively
low outside temperatures in order
to maintain the temperature set on
the dial.
If cool air from upper out­
lets is objectionable, adjust upper
outlets
as desired.
For window defogging -Move
the lever
to BI-LEVEL to divert a
portion of the conditioned air
through the defroster ducts and up-
2-23
per outlets when interior window
fogging
is encountered.
For windshield de-icing -With
the lever in the
DEF position the
system directs most of the airflow
at full heat and high blower speed
through the defroster ducts.
Some
airflow is also directed to the floor.
Air-Conditioner
Operating Tips
Close all windows and vents
when operating air system except
for the
first few minutes of opera­
tion when the car interior is very
hot. Close the windows
as soon as
the excessively heated air has es­
caped.
