Automatic ventilation
The system automatically selects the outside (fresh) air position when the climate control system operates over a certain
period of time (5 minutes) in low temperature with the recirculated air position selected.
To cancel or reset the Automatic Ventilation
When the air conditioning system is on, select Face Level 
mode and press the recirculated air position more than five times within 3 seconds while pressing A/C button.
When the automatic ventilation is canceled, the indicator blinks 3 times. When the automatic ventilation is activated, the indicator blinks 6 times.
