If the service light keeps appearing on the dashboard display of your Mercedes A-Class, you need to manually reset it to eliminate it permanently. Contrary to what you might think, the entire operation is very simple and can be done independently without the need for an expert.

First, insert the key and turn on the ignition. Then, navigate through the menu using the appropriate button (located on the left side of the steering wheel) until you find the total mileage option.

At this point, press the button located below the speedometer and then, using the "+" and "-" buttons on the right side of the steering wheel, navigate in the new menu until you find the vehicle maintenance option. Enter it and finally proceed with the reset.
