Automatic ventilation (if equipped)
The system automatically selects the outside (fresh) air position when the climate control system operates over a certain period of time (approximately 30 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 while pressing the A/C button, press the recirculated air position button five times within three seconds.
When the automatic ventilation is canceled, the indicator blinks 3 times. When the automatic ventilation is activated, the indicator blinks 6 times.
