The defogging button symbol in a car is a fan shape with three upward wavy lines inside. Here are specific methods for defogging inside the car: 1. Proper use of the air conditioning system: Park the car, start the air conditioning, turn the temperature adjustment button to the warm air direction, press the defogging button, and use the warm air from the air conditioning to dry the windshield fog. When defogging, you can switch the air conditioning to external circulation to allow fresh outside air to enter the cabin. Setting the compressor and fan speed to 25°C or higher can speed up the defogging process. 2. Use specialized anti-fog products: Before each use, spray evenly on the windows and wipe clean, forming a transparent protective film on the glass to prevent fog formation. One application can prevent fog for about ten days to half a month. 3. Cold and hot air convection: If the fog is not heavy, you can open a crack in the windows on both sides to allow air convection inside the car. The temperature inside the car will gradually approach the outside temperature, and the fog will dissipate.

I hate it when the car fogs up, especially on rainy winter days. In this case, you need to press the windshield defogger button, the one with a fan icon and three wavy lines in the middle, which can be found on the central air conditioning panel. After 15 years of driving, I've learned that when using this button, you should also turn on the AC switch to activate the compressor for faster dehumidification. For manual air conditioning, adjust the temperature to the cold air setting, while for automatic air conditioning, simply pressing AUTO is the most hassle-free. Remember to use the external circulation mode to let fresh air in, as it defogs much faster than internal circulation. When defogging, it's best to set the fan speed to maximum and not turn it off immediately—keep it blowing for two or three minutes to ensure the glass dries completely. If the rear windshield fogs up, press the nearby square icon with wavy lines, which activates the heating wires. To prevent fogging, you can blow hot air on the glass for five minutes before setting off or buy an anti-fog spray and apply it once a month for good results.

I remember when I first bought the car and encountered fogging, I frantically pressed all the air conditioning buttons. Now I've found the simplest solution: just press the front defroster button with the fan-shaped symbol. This button has a unique feature—once pressed, the system automatically increases the fan speed to blast air onto the windshield. In summer, using cold air works best, clearing fog in just 30 seconds. In winter, wait until the engine warms up and use warm air; initially, the fogging might worsen, but it'll clear up soon. New drivers often forget to turn on the external circulation, but actually, external circulation is 50% more efficient at defogging than internal circulation. If the rear window fogs up, press the square-shaped heating defroster button, but don't use it too frequently—keep each session under 10 minutes. Here's another tip I've discovered: wiping the inside of the windshield with a dry towel before driving can delay fogging. On rainy days, it's best to turn on the defroster in advance—don't wait until your vision is blurred to deal with it.

Foggy windows blocking your view is extremely dangerous! My first move is pressing the front defroster button—located on the air conditioning panel to the right of the steering wheel, with a fan-shaped icon. After pressing it, the airflow will suddenly increase, so wait patiently for about 20 seconds. The key is to turn on the AC switch, which is crucial for dehumidifying and defogging. Also, adjust the air direction to the windshield arrow mark position. If the fog is very thick, it's best to pull over first—safety comes first. I never wipe the glass by hand—it's unsafe and leaves oil residue that makes fogging worse. It's recommended to check the cabin air filter every six months; a clogged filter reduces defogging effectiveness. Remember, for rear window fogging, press the square-shaped button, which is separate from the front fan-shaped one.
