What does the rear switch in a car mean?

[Aubree]

Rear means the back or rear part, and you often see a button labeled rear on the control panel of the dashboard. Additional information: 1. Button symbol: Generally, this button also has a symbol, which looks like a rectangle with three upward wavy lines inside. This button is the rear window defroster switch. When the rear window is fogged up or there is a large amount of snow on the outside of the rear window, you can turn on this button, and the many horizontal heating wires in the rear window will start heating to remove fog and snow from the glass, ensuring driving safety. 2. Rearview mirror heating function: For some higher-configuration vehicles, this button has another function, which is the rearview mirror heating function. When this button is turned on, vehicles equipped with rearview mirror heating will also start heating the rearview mirror lenses. After turning on this button, the function will automatically stop after a period of heating, as prolonged heating can cause glass products to crack. Therefore, it is recommended not to use it continuously to protect the vehicle.
