How to Turn on the Car Heater in Winter?
2 Answers
After starting the engine, do not turn on the heater immediately. Wait until the car has driven a certain distance and the water temperature gauge reaches half of the normal operating temperature before turning on the heater. When first turning on the heater, start with a low fan speed. Once the water temperature reaches normal levels, adjust the fan speed according to personal preference. Here are some related tips: 1. Increase Humidity: After using the heater for a while, you may notice dryness in your mouth and throat, making breathing uncomfortable. This is because winter air in northern regions is already dry, and using the heater in a closed environment exacerbates the dryness. To alleviate this, you can slightly open the window for ventilation. Alternatively, you can use a car humidifier or hang a damp towel in the car for effective humidification. 2. Set the Airflow Direction Properly: As the principle goes, cold air sinks while warm air rises. This should also be considered when using the car heater. In winter, adjust the airflow direction to blow toward your feet. This prevents noticeable breathing discomfort and ensures efficient heating. Avoid directing the heater airflow directly at your face, as prolonged exposure to dry hot air can cause discomfort and dry out facial skin, accelerating aging.
I usually wait for the engine to warm up before the heater becomes effective. In winter, after getting in the car, I start the engine and let it run for a few minutes until the temperature gauge needle rises to near the midpoint before operating the heater to avoid blowing cold air and discomfort. Then, I locate the temperature knob in the air conditioning control area and turn it toward the red dial to set the ideal temperature, such as around 20-24°C. Don’t set the fan speed too high initially—start with a low speed and adjust it once the car interior warms up. If the windshield fogs up, I immediately use the defogger function button to clear it. I also prefer using the external air circulation mode to maintain airflow and reduce drowsiness. When using the heater, don’t overlook regular maintenance—check the coolant level and the heating system to ensure long-term reliability, making the entire winter driving experience comfortable.
