The information and entertainment facilities arranged within the driver's reach are supplemented by an acoustic, settable time signal apparatus which is preferably assigned to the radio section and integrated therein. This enables the driver to monitor the driving time not only visually but also acoustically. In case of need, therefore, he can arrange a rest without having to fear oversleeping. A significant reduction in the accident risk resulting from overtiredness can thus be achieved with a time-signal apparatus of this type. <IMAGE>
