Hyundai Tucson: Manual Heating and Air Conditioning / Air intake control

To select outside (fresh) air or recirculated air, press this button.

Recirculated air position

With the recirculated air selected, air from the passenger compartment is drawn through the climate control system.

Outside (fresh) air position

With the outside (fresh) air selected, air enters the vehicle from outside and is drawn through the climate control system.

Information

Using the system in the fresh air position is recommended.

Prolonged operation of the heater in the recirculated air position (without air conditioning selected) can cause fogging of the windshield and side windows and the air within the passenger compartment will 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.

WARNING

To prevent serious injury or death:

• Continued climate control system operation in the recirculated air position may allow humidity to increase inside the vehicle that could fog the windshield and the side windows and obscure visibility.
• Do not sleep in a vehicle with the air conditioning or heating system on.
• Continued climate use of recirculated air may cause drowsiness or sleepiness, and loss of vehicle control. Set the air intake control to the outside (fresh) air position while driving.
