Unplugging: first press the ‘unlock’ button on the key, then disconnect the cable from the car and then from the charging point, and store it in the boot. On some models of vehicle, the button for disconnecting the cable may be located on the dashboard, or on the car near the cable charging connector (on the Toyota Prius, for example).
Connect: retrieve the cable from the boot, open the charging hatch and then connect the cable to the vehicle and then to the charging point. Place the cable in the socket, then turn and push. You can then use the red token attached to the keys on the contactless zone above the charge point to activate charging. The bollard light should be blue.
