Method for assisting in maintenance of a motor vehicle

A method for assisting in maintenance of a motor vehicle having a vehicle drive motor and a drive energy storage device, which has a filling level measuring device, comprising:

• identifying a request for a maintenance process on the motor vehicle as a maintenance request by a self-monitoring device of the motor vehicle;
• transmitting the maintenance request as a maintenance indication to a driver of the motor vehicle by an information device arranged in the motor vehicle,
• wherein the maintenance indication is transmitted to the driver as a function of a switch-off filling level present when the vehicle drive motor is switched off and detected by the filling level measuring device, the maintenance indication being transmitted when one of:
• the switch-off filling level is lower than a preset filling level threshold value and
• a filling level difference between a switch-on filling level, present when the vehicle drive motor is subsequently switched on again and which is detected by the filling level measuring device, and the preceding switch-off filling level indicates a positive filling level value,
• wherein the maintenance process corresponding to the transmitted maintenance request and the transmitted maintenance indication comprises a non-fuel level related maintenance process, and
• wherein two different transmission presets are provided in the motor vehicle,
• a first preset being set for the motor vehicle, with the maintenance indication being transmitted in accordance with a first transmission preset only when the switch-off filling level is lower than the filling level threshold value, and
• a second preset being set for the motor vehicle, with the maintenance indication being transmitted in accordance with the second transmission preset only when the filling level difference between the switch-on filling level and the switch-off filling level is greater than the filling level value.
