How do i change the clock display on my citreon c4?

To change the clock display on your Citroën C4, start by pressing the "Menu" button on the dashboard or infotainment system. Navigate to the "Settings" or "Time" section, where you can adjust the time format and set the current time. Use the buttons or touchscreen to modify the hours and minutes, then confirm your changes. If your model has a physical clock, there may be a separate knob or button to adjust the time directly.
