Which button to press for defogging in the car?
2 Answers
To defog the car, simply press the defogging button. For manual air conditioning: Turn on the front window defogging mode, then set the fan speed to maximum, turn on the AC switch, and adjust the temperature to the lowest setting. The fog on the glass will disappear shortly. Some models are equipped with rear window electric heating and exterior rearview mirrors; just press the switch to activate them, and the fog will clear in about a minute. For automatic air conditioning: Generally, you only need to press the one-touch defrost button. After pressing it, the fan speed automatically increases to maximum, and the external circulation is activated, making it both practical and convenient. You can also use the heating system to defog. The fog on the car windows is caused by the temperature difference between the cold outside and the warm inside. When the temperature inside the car is higher than the outside temperature, fog forms.
Having driven for many years, fogging up inside the car is a common occurrence for me. Simply press the front windshield defogger button—it's located on the control panel with an icon resembling a fan shape or wavy lines. When pressed, the fan will operate at maximum intensity, blowing either hot or cold air to quickly clear the fog. If the rear window fogs up, use the rear defogger button, which looks like a rectangle with a wavy line inside. Turning on the air conditioning for dehumidification is even more effective, as fogging is caused by moisture condensation due to temperature differences inside and outside the car. Cracking a window or adjusting the air recirculation can also help clear the fog. Preventing fogging is equally important: wipe the windows clean before driving, warm up the engine in winter, and keep windows closed in summer to prevent humid air from entering. Remember, the operation is simple, but safety comes first—slow down if visibility is poor before addressing the fog.
