How to Set One-Touch Up/Down for BMW 3 Series Windows?
2 Answers
To set the one-touch up/down function for BMW 3 Series windows, press and hold the unlock button after locking the car to close all windows at once, and press and hold the unlock button after unlocking to open all windows. Generally, car window control switches have two positions: the first position functions like a regular power window. Here are details about one-touch window operation: 1. One-touch up/down refers to a system where car windows can be fully opened or closed with a single button press. 2. The first switch position works like a standard power window; the second position allows the window to automatically open or close completely with a single press and release. 3. Cars equipped with one-touch window functionality also feature anti-pinch protection. Do not attempt to test this function with any part of your body.
When I was tinkering with the BMW 3 Series window settings, I found it actually quite simple. First, you need to start the vehicle or at least make sure the dashboard is lit. Locate the window button near the driver's door handle, press and hold the button for the window you want to set, and lower the glass completely. After it reaches the lowest point, keep holding the button for another 5 to 10 seconds. Then, perform the opposite operation by raising the window to the top and continue pulling the switch for 5 to 10 seconds. Finally, release and lightly tap the switch to test—if the glass moves automatically to the bottom, it means the one-touch up/down feature has been successfully activated. Each window needs to be set individually, with the rear windows following the same method as the front ones. Once set up, it's incredibly convenient—just a light press to get your parking ticket, and you won't need to hold the switch to close the windows on rainy days.
