Is your Mercedes E350 showing a persistent service light? It’s a common reminder that your vehicle is due for maintenance. While Mercedes-Benz service intervals are essential for optimal performance, you might find yourself needing to reset the service indicator after completing maintenance yourself or ensuring the service has been performed. This guide offers a straightforward, step-by-step method to reset the service light on your 2009-2016 Mercedes E350 models, right in your garage, without any specialized tools.
Simple Steps to Reset Your Mercedes E350 Service Indicator
Follow these instructions carefully to reset the service light on your Mercedes E350. This procedure is designed for DIY enthusiasts and Mercedes owners who want to manage their car maintenance efficiently.
-
Initial Setup: Begin by getting into your Mercedes E350 and ensuring that all doors are fully closed. This is crucial for the system to properly register your commands.
-
Ignition Activation: Insert your key into the ignition slot. Turn the key to position 1. This is the first click, where the car’s electronics are powered on, but the engine is not started. Avoid turning to position 2, as this will start the engine, which is not required for this process.
-
Access Instrument Cluster Display: Check your instrument cluster. If the temperature or mileage display is not currently visible, use the menu selection buttons on the left side of your steering wheel. These buttons, often depicted as rectangles or “windows,” allow you to cycle through the different display options until you reach the temperature/mileage screen.
-
Initiate Reset Sequence: Locate the ‘Reset’ button. This is typically a small, black, stem-like button situated on the left side of the instrument cluster, near the speedometer and menu array. Quickly press this ‘Reset’ button three times in succession. After the third press, the screen should change to display “UB: XX.XV”. This indicates the battery voltage reading. Important: Ensure you press the button quickly three times and release. Holding the reset button down will reset the trip odometer instead of initiating the service menu.
-
Navigate to Service Menu: Now, press the down-arrow button, which is the sub-menu navigation button on the left side of your steering wheel, just once. This action will guide you into the ‘Service Menu’ within the Mercedes system.
-
Select ‘Confirmation’ Sub-Menu: Use the ‘+/- Selection Marker’ buttons located on the right side of your steering wheel. These buttons are used to scroll through options within menus. Scroll downwards through the sub-menus until you highlight the ‘Confirmation’ option.
-
Enter ‘Confirmation’ Menu: On the left side of your steering wheel, press the right-hand ‘Next Menu’ button. This action will select the ‘Confirmation’ sub-menu and display its options on your instrument cluster screen.
-
Choose ‘Full Service’: Once again, utilize the ‘+/-‘ buttons on the right side of the steering wheel to navigate through the ‘Confirmation’ menu options. Scroll until you find and highlight ‘Full Service’.
-
Confirm Service Completion: Finally, to confirm the service and reset the light, press the right-hand ‘Next Menu’ button on the left side of the steering wheel one last time. If successful, your display should now read “Service Confirmed.” This message indicates that the service light reset procedure has been completed.
-
Exit Service Menu: To fully exit the service menu and return to the standard display, press the ‘Previous Menu’ button (the left-hand button on the left side of the steering wheel) several times. Continue pressing until you are back to the main display showing your mileage and temperature.
Final Steps and Verification
After completing these steps, the service light on your Mercedes E350 should be successfully reset. It’s advisable to start your vehicle and possibly drive for a short distance to ensure the service message does not reappear. This procedure is a helpful way to manage your Mercedes E350’s maintenance reminders, ensuring you stay informed about your vehicle’s service needs while maintaining control over your car care.
Important Note: This guide is intended for resetting the service indicator after maintenance has been performed. Always adhere to the recommended Mercedes-Benz service schedule to ensure your vehicle remains in optimal condition and to uphold its longevity and performance. If you are unsure about any aspect of your vehicle’s maintenance, always consult a certified Mercedes-Benz technician.
