After changing the engine oil in the Mercedes GLC, you need to reset the system that alerts you to the need for service. Sit in the driver's seat and turn the ignition key to position two, then press the phone and OK buttons simultaneously until a menu appears on the central display.

Select "assyst plus" from the menu, activate the ignition with the key, press "OK", and select "full service". Go to "validate service" and press "OK", select the oil quality, confirm the next option, and the display will show a confirmation message for the reset.
