How to Turn on the Heater in a 2021 Hyundai ix35?
2 Answers
Use the one-touch start button to start the vehicle and allow the engine coolant temperature to rise. Locate the air conditioning button on the center console. Press the AC button to activate the air conditioning system and increase the fan speed. Use the temperature knobs on both sides to turn clockwise and raise the temperature. The small screen above the knobs will display the temperature. Turn on the interior air recirculation button for better heating efficiency, then turn it off once the cabin has warmed up. It is recommended to direct the warm air towards the feet, as blowing it towards the face may cause drowsiness. The heater delivers warm air into the cabin via the blower.
When I first got my hands on the 2021 Hyundai ix35, I also figured out the heating operation—it's quite straightforward. First, start the engine and let it idle for two to three minutes to warm up, since the heating system utilizes waste heat from the engine. Then, look at the air conditioning panel on the center console, find the temperature knob, and turn it clockwise to increase the temperature—anything above 25°C feels comfortably warm. For convenience, you can simply press the AUTO button, and the system will automatically adjust the fan speed and temperature to balance the cabin environment. If the airflow feels weak, manually press the fan button to increase the output. In cold winter weather, it's advisable to turn on the recirculation button to allow hot air to circulate inside the car faster. Additionally, if the windows fog up, don’t forget to press the defogging mode to ensure clear visibility. Overall, the design is very user-friendly—just remember not to blast the fan immediately after starting the car; wait until the engine warms up for safer and more effective operation. These steps apply to most situations in daily use, but regular maintenance of the AC filter can enhance the experience.
