B670C01Y-AATAir Intake Control
This is used to select fresh outside air or
recirculation inside air.
Fresh
Recirculation
With the " " mode selected, air enters the
vehicle from outside and is heated or cooled
according to the other functions selected.
With the " " mode selected, air from within
the passenger compartment is drawn through
the heating system and heated or cooled ac-
cording to the other functions selected.
NOTE:o It should be noted that prolonged opera-
tion of the heating system in " " mode
will give rise to fogging of the wind-
shield and side windows and the air
within the passenger compartment will
become stale. In addition prolonged use
of the air conditioning with the " " mode
selected may result in the air within the
passenger compartment becoming ex-
cessively dry.
o When the ignition switch is turned "ON"
the air intake control will change to " "
mode (regardless of switch position).
This is normal operation.
B670D04A-AATAir Flow Control
This is used to direct the flow of air. Air can be
directed to the floor, dashboard outlets, or
windshield. Five symbols are used to represent
Face, Bi-Level, Floor, Floor-Defrost and De-

in through the grilles just ahead of the wind-
shield. Care should be taken that these are
not blocked by leaves, snow, ice or other
obstructions.
o To prevent interior fog on the windshield, set
the air intake control to the fresh air ( )
position and fan speed to the desired posi-
tion.
o When the A/C is operated continuously on
the floor-defrost level ( ) or defrost level
( ), it may cause fog to form on the exterior
windshield by the temperature differencial.
At this time set the air flow control to the face
level position ( ) and fan speed control to
the low position.
