Part: Service warning light

Let's see how to reset the service light on a Mercedes Classe C W205 that has the instrument cluster shown in the video. Insert the key and turn on the ignition, then quickly press and hold the three buttons: call + back + ok. A hidden service menu will appear, where we will use the up and down buttons to scroll through the options until we find "assyst plus" (which is the computerized maintenance system), and then press "ok." We are now in the service menu; scroll down to "confirm full service" and press "ok." We will be asked to confirm the specification of the oil we used: select the correct one and then confirm with "ok." Scroll down to the option "Service carried out?" and confirm, and the display will show a confirmation message: "full service complete." Turn off the ignition and then turn it back on for verification.
