What does autodown mean in a car?

[Bailey]

Autodown in a car means one-touch down, where pressing the down button once automatically lowers the window glass to the bottom. This feature is generally found on the window regulator switch, indicating that the car's window glass regulator only supports one-touch down and not one-touch up. Here is some additional information: 1. One-touch window operation: One-touch window operation refers to a system where the car window glass can be controlled to move up or down with a single press of a button. This feature is typically found in mid-to-high-end models, primarily for the convenience of drivers and passengers, and to prevent the driver from being distracted by operating the windows, thereby improving safety. 2. Function introduction: Cars equipped with one-touch window operation have a two-stage window control switch. The first stage works like a regular power window, requiring the switch to be held until the window reaches the desired position, at which point releasing the button stops the movement. The second stage only requires a single press and release, and the window will automatically open or close completely. The one-touch operation indicators vary among different car models, with most currently featuring the English label "Auto."
