Ventilation
Setting the air source select lever to "FRESH" position
allows the heating system to work with sending the fresh
air from outside.
The blower fan also serves to deliver fresh outside air to
the passenger compartment to assure adequate
ventilation.
Air Select Knob
The air select knob allows you to direct heated air into the
passenger compartment through different outlets.
1. Vent – In this position, air is discharged from the
upper air outlet. Air quantity is controlled by the fan
control lever.
2. Bi-Level – In this position, air flow is divided between
the upper air outlets and the floor air outlets, with
warmer air delivered to the floor outlets than the air
delivered to the upper air outlets when the temp lever
is in middle position.
The fan control is used to control the amount of air sent
out by the resistor at four levels from "LOW" to "HIGH".
(4) Air Conditioning (A/C) Switch (W/ A/C)
(5) Temperature Control Knob
(6) Middle Position
3. Foot – In this position, air flow is delivered to the foot,
while sending a small amount of air to the windshield.
4. Def/Foot – In this position, air flow is delivered to the
foot, while sending approx. 40% of total amount of air
to the windshield.
Selecting this mode allows air conditioning system to
work while the fan switch is turned to on position, even
if the A/C switch is off.
5. Defrost – In this position, most of the air is delivered
to the windshield and a small amount is delivered to
the side windows.
Selecting this mode allows air conditioning system to
work while the fan switch is turned to on position, even
if the A/C switch is off.
Moving the air source select lever to the "CIRC" position
provides quickest heat delivery by closing the blower
assembly mode door. In this position, outside air is not
delivered to the passenger compartment.
