Operation Tips
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.
