A system and a process are provided so that a transmission, which is automatically shifting per se, can be operated a driving position switch for a first automatic operating mode and a switching rocker for a second operating mode influenced by the driver. In order to provide such a system and a process which has a selecting device and can be influenced for a short time by the driver, the control unit changes, from the automatic operating mode normally selected in a position D of the first selecting device (of the driving position switch), without the selection by the first selecting device, temporarily into the operating mode influenced by the driver when a second selecting device (a rocker or another signal device) arranged on the steering wheel is actuated.

A roof construction for a vehicle has a large-surface roof opening which is surrounded by vehicle-body-side member sections and which can be closed by at least one movable forward roof section and an adjoining tail gate. The forward roof section is displaceable toward the rear of the vehicle and under the tail gate by way of laterally arranged vehicle rails extending in the longitudinal direction of the vehicle and by way of driving devices. In order to simplify and shorten assembly work at an assembly line, the at least one movable roof section, the assigned guide rails, the tail gate and the driving devices are accommodated by a surrounding carrying frame and, together with the carrying frame, form a prefabricated module. Together with the insertion of a surrounding sealing element, the prefabricated module is connected with the vehicle-body-side member sections.

By means of the device and the process, a defective pneumatic tire of the vehicle is provided with emergency running properties. This takes place by means of an inflating device, after the removal of which from the loading space, a signal is triggered, which constantly reminds the driver to move the vehicle only within the range of predetermined speeds. By means of the process, it is ensured that improper actions which would be possible in connection with the pneumatic tire with emergency running properties, are largely avoided.
