What does a square with three curved arrows pointing upwards represent?

A square with three curved arrows pointing upwards is the rear window defroster switch. Function of the rear window defroster switch: On the car's center console, there is a button depicting a small square with three small arrows pointing upwards. This is the rear window defroster switch. Pressing this button activates the heating resistor wires on the rear window to start heating. In winter, if the rear window is covered with snow, this function can also automatically remove the snow accumulation. Steps to activate the rear window defroster switch: First, open the driver's side door, then press the brake pedal. Operation of the defroster switch: The defroster switch controls the defroster, which reduces moisture, fog, and frost on the front and rear glass surfaces to improve visibility. When there is fog inside the car, pressing the defroster switch will illuminate the indicator light, and the defroster will operate for a period of time until the fog on the glass dissipates. After a predetermined time, the defroster automatically turns off. To manually turn off the defroster, press the defroster switch again.
I've been driving for over 20 years and often see this symbol: the square actually represents the car body, with three curved arrows pointing upwards, meaning the traction control system is turned off during turns or skids. I pay special attention to it on snowy roads because with the system off, the wheels can easily lose grip, making the car slide dangerously like skating. Normally I keep the system on, only manually turning it off when testing high speeds on dry roads, but that requires experience. New drivers are better off not touching the switch and keeping it on to prevent accidents. The button is usually near the steering wheel - a yellow light means the system is off, green indicates normal operation, and checking the manual makes it clear.
