After starting the vehicle, turn off the AC button of the air conditioning. When the water temperature rises to the normal value, turn on the warm air of the air conditioning. How to use the car air conditioning: First, start the vehicle and let it warm up. Wait until the water temperature reaches around 70, then turn on the warm air of the air conditioning. Next, press the air recirculation button, and it will light up. Rotate the knob in the temperature control area of the air conditioning to the red zone. If there is a digital display, increase the temperature. There is no need to turn on the AC, as the heat generated by the engine will provide warm air through the car's recirculation function. Precautions for using warm air in winter: Do not turn on the warm air immediately after starting the car. If the engine is not warmed up, turning on the warm air will not only be ineffective but also consume a lot of electricity. First, start the engine and let it warm up. After the engine temperature rises, then turn on the warm air. Initially, set the air to external circulation to expel all the cold air inside the car. Then, switch to internal circulation for more effective heating.

From my experienced friend who's been driving for over a decade, adjusting the car's heating system is actually quite simple. First, start the engine and let the air conditioning system warm up for a while. Then, locate the temperature control knob on the center console, turn it to the red zone or high-temperature indicator, turn on the fan button to increase the airflow, and choose the footwell or windshield position, which is most suitable for winter driving. If it doesn't get warm after a while, it might be due to insufficient coolant or a clogged heater core, so it's recommended to check the air filter and cooling system during regular maintenance. Setting the temperature to around 24 degrees is most comfortable in cold weather, avoiding setting it too high to prevent stuffiness or window fogging. Remember not to get distracted after adjusting and focus on driving safely.

As a tech enthusiast, let me explain that the heating system in a car primarily relies on heat converted from the engine. The engine's cooling system heats the heater core in the air conditioning system via a pipe, and when the fan blows air through it, warm air is produced. To operate it, turn the temperature control knob to the high-temperature zone, adjust the airflow intensity with the fan speed button, and direct the vents toward your chest or set it to defrost mode. In summer, ensure the compressor is functioning properly to switch between hot and cold air promptly, and check the antifreeze level as too low a level can affect heating efficiency. The comfortable temperature range inside the car should be adjusted between 20-28 degrees Celsius.

I'm reminding you from a safety perspective. When adjusting the heater while driving, don't fumble around and obstruct your vision. Wait until the car is stationary or at a red light before making adjustments. After turning on the air conditioning, set the temperature to a comfortable range, such as above 25 degrees, with the fan at medium intensity to maintain quietness and avoid distraction. If it's not heating up, check if the air ducts are blocked or the filter is dirty, and clean them promptly to prevent odors from affecting breathing. In winter, warm up the car for a few minutes before driving and then adjust the heater for safer and more efficient operation.
