How to Turn on the Car Defroster?

Car defroster switch: The front windshield defroster is represented by a fan-shaped pattern with three upward lines, and the rear windshield defroster is represented by a rectangular pattern with three upward lines. Press the corresponding button to activate it. Below is an introduction to the defroster: 1. The function of the defroster is to capture mist particles and slurry droplets carried by the flue gas during the spray absorption process. 2. The defroster mainly consists of plates and a support device. The plates are usually made of two types of materials: polymer materials (such as polypropylene PP, FRP, etc.) or stainless steel (such as 316L, 317L, etc.). They are generally divided into streamlined and folded types.
When driving in heavy fog, I quickly press that fan-shaped button on the dashboard—that's the front windshield defroster switch, and usually the fan automatically adjusts to maximum. Set the temperature a bit higher, like above 26°C, and turn on the AC for faster dehumidification. If the rear window fogs up, press another button with a square-shaped symbol. When I first bought the car, I often made mistakes, like forgetting to turn on the AC, and the fog wouldn't clear for a long time. In winter, let the car warm up for a few minutes before turning on the defroster for better results. Remember to clean the cabin air filter regularly to prevent dust from affecting airflow efficiency—safe driving comes first. Some cars have an automatic mode; pressing AUTO lets it adjust intelligently, which is quite handy, but manual control is more reliable in sudden fog. In short, don’t rush to hit the road before the fog clears—poor visibility poses high risks.
