Unplug: You must first press the "unlock" button on the key, disconnect the cable from the car and then from the bollard and store it in the trunk.
Connect: you must retrieve the cable from the trunk, open the charging hatch, connect the car with (picto car) the cable and then pass the red key badge on the contactless area above the terminal. The light on the bollard flashes blue. Position the cable in the socket, turn, and push. The light freezes to blue if the cable is properly connected.
