How to Turn on the Heater When There's AUTO in the Car?

Press the "AUTO" button, and the automatic air conditioning will adjust automatically based on the temperature inside the car. You should first start the engine to warm it up, wait until the engine temperature gauge needle reaches the middle position. Turn on the heater air conditioning, and set the air circulation to external circulation to allow the cold air inside the car to be expelled. After waiting for 2 to 3 minutes, set the air circulation to internal circulation. Choose an appropriate air conditioning temperature. Setting the temperature too low in summer can affect health, so the air conditioning temperature adjustment must be appropriate.
Turning on the heater in the car is actually quite simple, and I often do it this way. First, start the vehicle and wait a few minutes for the engine to warm up. Then press the AUTO button on the center console, and the air conditioning system will start operating automatically. At this point, rotate the temperature adjustment knob to set it a bit higher, for example, to around 28°C, and the system will automatically blow warm air based on the difference between the interior temperature and the set temperature. If the air is cool at first, don't worry—it might just mean the car engine hasn't warmed up enough yet. Just wait a little longer. When I use the external circulation mode, the warm air comes in faster, but it's not suitable for use in traffic jams because it can draw in exhaust fumes. I've also found that regularly cleaning the air filter helps distribute the heat more evenly, so my hands and feet don't get cold while driving in winter. Overall, the AUTO mode is very convenient as it automatically adjusts the fan speed without manual intervention, but make sure the car is running smoothly before adjusting the temperature.
Here's how I understand it: When you press the AUTO button to turn on the heating, the key lies in the temperature setting. After starting the vehicle, let the engine warm up a bit, then press the AUTO button to activate the automatic system. Next, turn the large knob to increase the temperature setting, for example, to 24 or 25 degrees or above, and it will automatically switch to heating mode. The system internally monitors sensor data—if the cabin is cold, the fan will blow stronger to deliver warm air; otherwise, it reduces the airflow. I've also noticed that some cars come with heated seats or steering wheel functions, which, combined with the heating system, provide exceptional comfort. In daily use, if the heating isn't working, check if the coolant level is sufficient or if the filter is clogged. Using recirculation mode helps minimize heat loss, but switch to fresh air mode periodically for ventilation. Overall, this method is both efficient and safe, especially when driving in cold weather, avoiding the hassle of manually adjusting the fan. Make it a habit to check the system status before each trip, and during long drives, the heating won’t consume too much fuel.
