How to Turn On the Car's Heater?
3 Answers
The method to turn on the car heater is: 1. Start the car by igniting it, wait for the engine to warm up and the coolant temperature to reach the normal level, then rotate the air conditioning fan speed button to turn on the heater—there is no need to press the AC button; 2. Adjust the air conditioning circulation mode to internal circulation and set the air direction to blow forward and towards the feet. The car air conditioning system is designed to regulate and control the temperature, humidity, air cleanliness, and airflow inside the vehicle to an optimal state, providing passengers with a comfortable riding environment, reducing travel fatigue, and creating favorable working conditions for the driver. It serves as a crucial ventilation device for ensuring safe driving, generally including cooling, heating, and ventilation systems.
I've got plenty of experience with this - no heating in winter is absolutely brutal! First, start the car and let it warm up for 3-5 minutes until the coolant temperature gauge needle reaches the middle position before turning on the heater. Turn the temperature knob on the AC panel to the maximum setting in the red zone, and remember to turn off the AC button (that's for cooling) - setting the fan speed to level 2 or 3 is most comfortable. If the windshield fogs up, adjust the vents to windshield defogging mode and turn on external air circulation - it works wonders for clearing fog. On long drives, open the windows every two hours for some fresh air to avoid feeling stuffy. Oh, and using the heater barely affects fuel consumption, so feel free to use it generously!
Here's a little trick from an experienced driver: To get hot air quickly, turn on the external circulation for 30 seconds first to bring in the engine's heat, which warms up twice as fast as using internal circulation directly. If the heater isn't performing well, first check if the antifreeze is low, then feel if the lower hose is warm. I've encountered cases where a clogged radiator caused the heater to stop working entirely. Nowadays, automatic climate control in new cars makes things easier—just press the AUTO button and you're set, but remember not to set the temperature above 25°C, or it'll feel like an oven. Directing warm air at your feet is the most relaxing way to drive long distances without stiff legs.
