To remove interior fog on the windshield –
Push the "FRONT WINDSHIELD" button.
To remove frost or exterior fog on the windshield –
1. Turn the "TEMP" knob at the maximum temperature.
2. Push the "FRONT WINDSHIELD" button.
3. Push the fan speed control button on the right side to
obtain a maximum air flow.
4. Leave the air conditioning on–off button off.
When the "FRONT WINDSHIELD" button is pushed, air
flows mainly from the windshield vents and the
OUTSIDE AIR mode is automatically set. This setting
clears the front view more quickly.
If you want to return the setting to RECIRCULATED AIR
mode, push the air intake control button once again.
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.
Pushing the "FRONT WINDSHIELD" button turns on the
defroster–linked air conditioning. At this time, the "A/C"
button indicator comes on regardless of whether or not
the "A/C" button is pushed in. This is to clean up the front
view more quickly.
To turn off the air conditioning alone, push the "A/C"
button once again.
When the "A/C" button is not pushed in, pushing another
air flow control button turns off the air conditioning.
Pushing the "FRONT WINDSHIELD" button once again
returns the air flow mode to the last one used.
