How to set up the one-touch window function for Citroen C5?

[DeSilas]

Locate the window control button (auto) on the left side of the driver's seat. Press and hold the button until the window is fully raised. After the window is completely closed, continue holding the button for approximately 2 to 5 seconds. When you hear a "click" sound, it indicates that the car's programming is complete. You can then release the button to activate the one-touch window function. One-touch window refers to the feature where the car window can be fully opened or closed with a single press, which is typically equipped in mid-to-high-end vehicle models.
