To enable one-touch window lift for the Sonata 8, you need to install a one-touch window lift module. Then, press and hold the window switch for about five seconds without releasing the button to activate the feature. Below is an introduction to the one-touch window lift function: 1. One-touch window lift refers to a system where the car window glass can be fully raised or lowered with a single press of a button. Cars equipped with this feature have a two-stage window control switch. The first stage operates like a standard power window. The second stage allows the window to automatically open or close completely with a single press and release of the button. In contrast, standard power windows require holding the switch until the window reaches the desired position. 2. Generally, mid-to-high-end models come with one-touch window lift functionality, primarily for the convenience of drivers and passengers, and to prevent drivers from being distracted while operating the windows, thereby enhancing safety. One-touch windows usually feature an anti-pinch function to avoid the risk of pinching fingers. Typically, only the driver's window has the one-touch lift feature. There is also a rear window lock switch; when pressed, it disables the window adjustment switches for the rear left, rear right, and front passenger windows, leaving only the driver's door switch operable for window adjustments.
