How to activate the one-touch up/down window feature on Citroen C-Quatre?

[MacAndres]

To activate the one-touch up/down window feature on Citroen C-Quatre, lower the window completely using the window switch, then hold the switch in the up position until the window is fully closed and continue holding for 10 seconds. Repeat this procedure for each window switch to complete activation. Additional relevant information is as follows: 1. Currently, most mid-to-high-end vehicle models are equipped with one-touch window control functionality. With standard power windows, users need to hold the switch until the window reaches the desired position. Vehicles with one-touch windows have two-stage control switches - the first stage operates like regular power windows, while the second stage allows automatic full opening/closing with a single press. 2. One-touch windows typically feature anti-pinch protection to prevent injury. Only the driver's window usually has one-touch control, as drivers are assumed to be responsible adults capable of safe operation, while other positions may not meet this requirement. This design prioritizes driving safety over cost reduction by minimizing distraction during window operation.
