only
as required for your
comfort.
• MAXIMUM HEAT REQUIREMENTS-Depress HEAT lever
to extreme down position.
If
heat becomes exces-
sive, pull up HEAT knob to desired position.
Additional rear seat
compartment heat may be

Heater Operating Tips
The Direct Air Heater receives air from the air inlet
louvers below the rear window. Clean snow from this
opening and surrounding areas before operating the
heater.
Operate the heater for several minutes before turn-
ing on the defroster. This will clear the system of moisture
and help prevent windshield fogging.
Keep all windows and vents closed to reduce drafts,
and noise.
Quicker defrosting may be obtained when the rear
seat heater outlets are closed.
NOTE: In Direct Air Heaters vapor may collect when vehicle stands for long periods, keep the HEAT lever in OFF position for the first
few minutes of engine operation. This will reduce the tendency for moisture to condense on windshield. Oil spilled on engine
shrouding may cause odor in passenger compartment. To avoid discomfort, the cause of any odor should be traced and defect
prom ptly corrected.
