What does the 'auto' on car windows mean?

[ColeLynn]

Window glass with 'auto' indicates that the window is equipped with one-touch up/down functionality. Pressing and releasing the button will lower all windows, while lifting and releasing the button will raise all windows. One-touch windows typically feature anti-pinch protection, where if an object is detected between the glass and window frame during automatic closing, the window will automatically stop and reverse to its initial position. The one-touch window function is designed for convenience, primarily to prevent drivers from being distracted by manually operating windows, thereby enhancing safety. The one-touch indicators vary across different car models, with most currently displaying the 'auto' label.
