A method for operating an industrial truck with an operating element comprising at least one operating for a vehicle function, an unlocking apparatus for the vehicle function, and a resetting apparatus configured to interact with the at least one operating lever generating a resetting force depending on a deflection of the least one operating lever. Upon an actuation of the operating lever without previously unlocking the operating lever, the resetting force acting on the at least one operating lever is changed in order to report an unsuccessful unlocking procedure.
