Abstract

A cruise control device has an activation device embodied as a key button. By activating the activation device it is possible to transfer the cruise control device, from a switched off operating state to a switched on standby operating state, and by a further activation of the activation device it is possible to transfer the cruise control device from the standby operating state to a switched on control operating state. The cruise control device has a storage device storing a state of the cruise control device immediately before the motor vehicle is switched off and a readout device which reads out the stored state of the cruise control device immediately after the motor vehicle is switched on. If the cruise control device had a switched on operating state immediately before the ignition device is last switched off, the cruise control device is transferred automatically to the standby operating state.
