the position. Be sure to return the control
to the position when the irritation has
passed to keep fresh air in the vehicle. This
will help keep the driver alert and comfort-
able.

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.
