Kia K900: Air intake control
This is used to select the outside (fresh) air position or recirculated air position.
To change the air intake control position, push the control button.
Recirculated air position

With the recirculated air position selected, air from the passenger compartment will be drawn through the heating system and heated or cooled according to the function selected.
When driving at high speed, the outside air may come in to circulate the air inside the vehicle.
To block the air from entering, press the air intake control button for about 2 seconds. The outside air will be blocked from coming in for 3 minutes.
Outside (fresh) air position

With the outside (fresh) air position selected, air enters the vehicle from outside and is heated or cooled according to the function selected.
✽ NOTICE
Prolonged operation of the heater in the recirculated air position (without air conditioning selected) may cause fogging of the windshield and side windows and the air within the passenger compartment may become stale. In addition, prolonged use of the air conditioning with the recirculated air position selected will result in excessively dry air in the passenger compartment.
