A method for operating a vehicle, in particular a motor vehicle, with at least one X-by-wire system, wherein the vehicle is transferred to a safe operating state within a defined period of time in the event of emergency operation, and wherein a predefined tolerance time interval is specified for the emergency operation, during which the emergency operation can be maintained at a maximum, in particular without an unreasonable risk. At least one information signal representing aging and/or wear of the X-by-wire system is determined and a duration of the tolerance time interval is varied dynamically as a function of the information signal.
