When the "FRONT WINDSHIELD" button is pushed while
operating in automatic mode, the air conditioning is set to

If you push the "FRONT WINDSHIELD" button once again
while in the FRONT WINDSHIELD mode, the mode then
returns to the last mode used.
CAUTION
Do not use the "FRONT WINDSHIELD" button during
cooled air operation in extremely humid weather. The
difference between the temperature of the outside air
and that of the windshield could cause the outer surface
of the windshield to fog up blocking your vision.
