How do you reset the Service light on a Mercedes A-Class?

Model: Mercedes Classe A W176 - Years 2012-2018
Part: Service warning light

It will be possible to completely remove the Service warning light from the instrument panel of the Mercedes Class A by turning on the instrument panel and navigating through the menu using the directional arrows on the steering wheel controls. You will then need to choose the icon with the wrench and select the ASSYST PLUS option. At this point, the option to select will be FULL SERVICE, and as you proceed, you will need to find the oil grade based on what was used for the top-up. This will bring up a screen asking whether to confirm the reset or not: by selecting "Yes," the Service warning light will be turned off.
