How do you reset speedometer on a Citroen Zsara?

To reset the speedometer on a Citroën Xsara, first, turn the ignition key to the "ON" position without starting the engine. Then, press and hold the trip odometer reset button (usually located on the dashboard) until the display resets to zero. This process typically clears the trip distance and may reset the speedometer reading, but the regular odometer remains unaffected. If the speedometer isn't functioning correctly, it may require further diagnostic checks.
