Service D 84 days past. Changed oil/filter that message won't clear

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. To reset the service light on your SLK300 after an oil change, you can follow this procedure: 1. Turn the ignition to position 1 (where only the lights on the dash come on, not the engine). 2. Scroll through the menu using the steering wheel buttons until you reach the mileage display. 3. Press and hold the "R" button (located on the left side of the instrument cluster) for about 3 seconds, and then press it again quickly. 4. A service menu should appear. Using the arrow keys, scroll to "Service Data" and "Confirm Full Service" and press "OK." 5. Confirm the reset by selecting "Yes" when prompted. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
