Windshield air flow button
When this button is pressed, air flows
mainly from the windshield vents and
turns on the defogging function with the
purpose of clearing the front view.
Pressing this button once again returns
the air flow mode to the last one used.
This button allows the air intake to select
FRESH automatically. This is to clean up
the front view more quickly. If you want
to return the setting to RECIRCULATE
mode, press the air intake selector button
once again.
Press the "A/C" button for dehumidified
heating or cooling. This setting clears the
front view more quickly.
