Abstract: A sliding door for a motor vehicle which is movable in a sliding motion into an opened and a closed position is provided with a main lock arrangement by which the sliding door can be fixed in the closed position, and an auxiliary lock arrangement which supplements the holding force of the main lock arrangement when the sliding door is in the closed position. In an improvement over conventional sliding door arrangements of this type, the auxiliary lock arrangement is used not only for supplementing the main lock arrangement when fixing the sliding door in the closed position, but also for fixing the door in the opened position.

Abstract: A motor vehicle with a control means and an electrically connected sensor. The sensor is used especially to detect the actuation of a door handle for opening a motor vehicle lock. In order to ensure high failure safety, the sensor for transmission of sensor signals has at least two electrically independent outputs which are connected to the control means via electrical signal lines.

Abstract: A sliding door for a motor vehicle, the sliding door being movable by a sliding motion into an opened and into a closed position, and having a fixing arrangement (2). The fixing arrangement (2) has an engagement module (3) and an engagement element (4), the engagement module (3) engaging the engagement element (4) when the sliding door is moved into the opened position and in this way fixing the sliding door in the opened position. It is proposed that the engagement module (3), when the sliding door has been fixed in the opened position, can be actuated by a drive in a motorized manner so that, in this way, the engagement element (4) is released and the sliding door can then be moved in the closing direction.
