Which button turns on the heater in a car during winter?

In a car during winter, the heater is turned on by the 'auto' button. The method for using the car's heater in winter is as follows: 1. Start the engine to warm it up; 2. Turn on the heater when the engine's water temperature reaches above 40 degrees Celsius; 3. Turn on the external circulation to expel the cold air inside the car; 4. Then switch to internal circulation. The working principle of a car's heater is: When the engine's water temperature becomes too hot, the refrigerant gas enters the condenser, where its pressure and temperature decrease, and the refrigerant gas condenses into a liquid, releasing heat. Methods for using and maintaining a car's air conditioning system include: 1. Do not set the temperature too low; 2. Control the direction of the air vents; 3. Avoid prolonged use; 4. Occasionally use a higher fan speed; 5. Turn off the air conditioning when driving at low speeds.
As a regular commuter who drives often, I find turning on the heater in winter is actually super easy. The main thing is to locate the rotary temperature control knob, usually marked with red or blue indicators on the dashboard or climate control panel—just turn it toward the red side to increase the temperature. Most cars don’t require a special button; simply adjusting the temperature control does the trick. I recommend starting the car and letting the engine warm up first—wait until the coolant temperature gauge rises a bit—before turning up the fan speed, as this delivers warmer air faster. Some newer cars have an AUTO button; pressing it will automatically adjust fan speed and temperature to your preset values. Remember not to activate the A/C cooling switch—that’s only for summer AC use, and engaging it in winter just wastes fuel. Always keep your eyes on the road while adjusting settings. Since knob positions vary by model, it’s best to glance at the manual when driving a new car for the first time—it’s safer and more convenient. A warm cabin makes the driving experience much better.
