How do you change a windscreen wash bottle on a saxo?

To change the windscreen wash bottle on a Citroën Saxo, first, ensure the vehicle is turned off and disconnect the battery for safety. Remove the front grille or any components obstructing access to the washer bottle, then detach the hoses and electrical connectors from the bottle. Unscrew or unclip the bottle from its mounting, replace it with the new one, and reattach everything in reverse order. Finally, reconnect the battery and test the system to ensure proper function.
