Kia Optima DL3: Heating and air conditioning / Temperature control

The temperature control knob allows you to control the temperature of the air flowing from the ventilation system. To change the air temperature in the passenger compartment, turn the knob to the right for warm and hot air or to the left for cooler air.

    The MAX A/C mode is used to cool the inside of the vehicle faster. Air flow is directed toward the upper body and face. In this mode, the air conditioning and the recirculated air position will be selected automatically.

    The air intake control is used to select the outside (fresh) air position or recirculated air position. To change the air intake control position, press the control button.
