Fig. 5: Air Intake Selector (Type A and B)
Item 2 - Function Selector
This selector controls the direction of the airflow from the vents. On
initial start during cold or high humidity temperatures the selector
should be placed in the defrost position and the fan speed set to 3 or
4. After the front and side windows become clear the selector can be
switched to defrost/heat and then to heat only as necessary and the
fan speed reduced. If the front or side windows begin to fog again
while driving the selector should be reset to the defrost/heat or full
defrost and the fan speed adjusted as necessary. In addition to the
above, air-conditioning can be used in conjunction with the heating
system to control the humidity level in the vehicle while providing
heat.

Item 3 - Temperature Selector Lever
This lever controls air temperature by sliding the lever either to
the right for hot or to the left for cold. On start up during cold
temperatures the selector should be set to the full heat position at
far right of the selectors travel. See Fig. 7.
As the interior of the vehicle reaches the desired temperature the
selector should be adjusted to the left towards the cold setting by
increments until the desired temperature is reached.
