Abstract
The invention relates to a method for operating a steering device (1), wherein at least one heating element (3) of a steering handle (2) of the steering device (1) is supplied with an electric heating current depending on a heating operation, wherein in a sensor operation an electrical capacitance (4) between at least two sensor electrodes (5, 6) of a sensor element (7) of the steering handle (2) of the steering device (1) is detected in order to determine manual operation of the steering handle (2). According to the invention, in an impedance detection operation, at least outside of the sensor operation an electrical impedance (8) between the at least two sensor electrodes (5, 6) of the sensor element (7) is detected, wherein depending on the detected impedance (8) a moisture content of the steering handle (2) is determined.
