Hyundai Sonata: Automatic climate control system / System Operation

Ventilation

1. Select the Face Level mode.

2. Set the air intake control to the outside (fresh) air position.

3. Set the temperature control to the desired position.

4. Set the fan speed control to the desired speed.

Heating

1. Select the Floor Level mode.

2. Set the air intake control to the outside (fresh) air position.

3. Set the temperature control to the desired position.

4. Set the fan speed control to the desired speed.

5. If dehumidified heating is desired, turn the air conditioning system on.

If the windshield fogs up, select the Floor & Defrost mode or press the Front Defrost mode.

Operation Tips

• To keep dust or unpleasant fumes from entering the car through the ventilation system, temporarily set the air intake control to the recirculated air position. Return the control to the fresh air position when the irritation has passed. This will help keep the driver alert and comfortable.
• To prevent the inside of the windshield from fogging, set the air intake control to the fresh air position and fan speed to the desired position, turn on the air conditioning system, and adjust the temperature control to desired temperature.

Air conditioning

All HYUNDAI Air Conditioning Systems are filled with environmentally friendly R-1234yf refrigerant.

1. Start the engine.

2. Push the air conditioning button.

3. Set the mode to the Face Level mode.

4. Set the air intake control to the recirculated air position. However, prolonged operation of the recirculated air position will excessively dry the air. In this case, change the air position.

5. Adjust the fan speed control and temperature control to maintain maximum comfort.

When maximum cooling is desired, set the temperature control to the extreme left position then set the fan speed control to the highest speed.

NOTICE

When using the air conditioning system, monitor the engine temperature gauge closely while driving up hills or in heavy traffic when outside temperatures are high. Air conditioning system operation can cause engine overheating. Continue to use the blower fan, but turn the air conditioning system off if the engine temperature gauge indicates engine overheating.

Air conditioning system operation tips

• If the vehicle has been parked in direct sunlight during hot weather, open the windows for a short time to let the hot air inside the vehicle escape.
• After sufficient cooling has been achieved, switch back from the recirculated air to the fresh outside air position.
• To help reduce moisture inside of the windows on rainy or humid days, decrease the humidity inside the vehicle by operating the air conditioning system with the windows and sunroof closed.
• Use the air conditioning system every month only for a few minutes to ensure maximum system performance.
• If you operate air conditioner excessively, the difference between the temperature of the outside air and that of the windshield could cause the outer surface of the windshield to fog up, causing loss of visibility. In this case, set the mode selection knob or button to the position and fan speed control to the lower speed.
