Is your Mercedes E350 displaying a service reminder even after completing the necessary maintenance? Don’t worry, resetting the service light is a simple process you can do yourself. This comprehensive guide provides a step-by-step walkthrough on how to reset service A on a Mercedes E350, clearing your dashboard and ensuring your vehicle’s maintenance tracker is accurate.
Understanding Mercedes-Benz Service Intervals
Mercedes-Benz utilizes a Flexible Service System (FSS) to schedule maintenance based on driving conditions and time. Service A is typically required every 10,000 miles or one year, whichever comes first. It usually includes an oil change, tire rotation, fluid checks, and a general inspection. While completing the service is essential, resetting the reminder is crucial to keep your dashboard clear and the FSS accurate.
Why Reset the Service A Light?
A persistent service reminder can be distracting. Resetting it offers several benefits:
- Clear Dashboard: Eliminates the annoying reminder and ensures a distraction-free driving experience.
- Accurate Tracking: Allows the FSS to accurately calculate the next service interval.
- Avoid Unnecessary Dealership Visits: Saves you time and money by avoiding a trip to the dealership for a simple reset.
Resetting the Service A Light on Your Mercedes E350
Follow these steps to reset the service A light:
Step 1: Turn on the Ignition
Insert the key and turn to position one or press the Start/Stop button without engaging the brake pedal. This activates the electronics without starting the engine.

Using the steering wheel controls, navigate to the trip odometer display. This usually involves pressing the “OK” or a similar button on the steering wheel.
Step 3: Enter the Vehicle Data Menu
Press and hold the phone answer/hang up button and the “OK” button simultaneously for approximately five seconds. This will access a hidden service menu. Release the buttons once the menu appears.

Step 5: Confirm the Reset
Select the “Full Service” option (or equivalent) and confirm the reset. The system might prompt you to confirm the oil grade used. Select the correct grade and press “OK.”
Step 6: Turn Off the Ignition
Turn off the ignition and then restart the car. The service reminder should be gone.
