By turning on the instrument panel and navigating through the menu using the steering wheel directional arrows, it will be possible to completely make the Service light of the Mercedes Classe A disappear. You will need to select the icon of the two English keys and then select the "ASSYST PLUS" option.

At this point, the option to select will be "FULL SERVICE", and moving forward you will need to choose the oil quality based on what was used for the replacement. Then a screen will appear asking whether to confirm the operation or not: by selecting "Yes", the Service light will have been completely reset.
