1. A method for signaling several items of information relevant for operating a motor vehicle having a drive unit, comprising:

  • representing different items of information by using unambiguous haptic signals at different positions of a control element of the vehicle;

    forming the different items of information by different fuel consumption values;

    respectively representing the different fuel consumption values by a characteristic of one of the haptic signals on the control element having a maximum at the associated position of the control element;

    determining a specific fuel consumption from a resulting setpoint value for an output variable of the drive unit and a current engine speed;

    converting said specific fuel consumption into a consumption per unit of distance value; and

    ascertaining the one of the haptic signals as a function of said consumption per unit of distance using an additional characteristics function.
