A cover panel, for at least partially transparently covering at least one display instrument in a vehicle, has a microstructure applied on at least one surface. The microstructure is suitable for scattering visible light which is incident on the cover panel. The at least one window region of the cover panel is cutout from the microstructure. A method for manufacturing such a cover panel uses a molding tool with an applied microstructure matrix for forming a microstructure on a part of the molding tool which is assigned to a surface of a molded cover panel. The parts of the molding tool which are assigned to window regions are cut out from the microstructure matrix.

A method for storing odometer reading data in a vehicle having control units which are connected via a data bus. The odometer reading data, which is determined at a particular time by an odometer, is stored in a storage means of a first control unit. This provides an alternative method for tamper-proof storage of odometer reading data and, in particular, improved protection against errors during the transmission of the odometer reading data. The current odometer reading data of at least one further control unit is then stored on the data bus in a storage means. The control units transmit the odometer reading data, which is stored at a particular time, onto the data bus at specific time intervals, and a control unit accepts the odometer reading transmitted onto the data bus if that reading is higher than its stored value, and uses that value for the further counting and storage in the particular control unit.
