The inscription on the computer's display shows a "child's seat error" (or "child protection"). Most often, it indicates that for some reason the doors are not locked (unlocked). We need to check the door lock device from the children (including a special button on the water door). Sometimes when a button is clicked, the locks are not blocked (at low temperature may freeze). Also, the error is highlighted on the display of the Renault Fluency, if the rear passenger-child pulls the handle of the door.
