What does mist mean on a car?

Mist on a car refers to the windshield wiper switch. The working principle and function of the windshield wiper are introduced as follows. Working principle of the windshield wiper: The working principle of the windshield wiper is that when the driver operates the wiper handle and sends the demand signal to the BCM (Body Control Module), the BCM inputs a start signal to the wiper motor, which then controls the wiper arm to perform the corresponding action. Function of the windshield wiper: The function of the windshield wiper is to remove raindrops and dust attached to the vehicle's windshield, thereby improving the driver's visibility and enhancing driving safety.
The 'mist' indicator on a car typically refers to the rear window defogger button. After driving for so many years, whenever I encounter rainy or cold weather with fogged-up windows obstructing my view, I simply press it. It quickly heats up to clear fog or frost on the glass, removing visibility obstacles. This function works by using the car's electrical current to heat thin wires embedded in the rear window glass—a straightforward mechanism. Nowadays, many vehicles integrate this with front window defoggers and even automatic climate control systems for enhanced overall performance. I recommend checking this button's functionality before each drive; don’t wait until an emergency to discover it’s faulty, especially when driving on slippery roads where clear visibility is crucial. Remember not to leave it on too long to avoid overheating and damaging the glass—proper long-term maintenance can extend its lifespan.
The 'MIST' button in the car refers to the rear window defogger. As a new driver, I was quite confused about it at first, but later learned that it's specifically designed to tackle fogged-up windows. When the weather is humid or there's a significant temperature difference between the inside and outside of the car, the rear window can easily become foggy. Pressing this button activates the heating defogging function, quickly restoring clear visibility. It's very simple to use: just press the button directly after starting the car, and it usually takes effect within seconds, making it ideal for rainy days or winter trips. If the effect isn't satisfactory, it might be due to power issues or blocked circuits, requiring a check of the fuse. I make it a habit to turn it on during long-distance drives to ensure safe driving—don't underestimate it, as it can prevent accidents in critical moments. Other similar functions include the front window defogger, and using them together can be even more effective.
