That persistent service indicator on your Mercedes Benz E350 2009 can be quite bothersome. While it’s essential to keep your vehicle well-maintained, sometimes you need to reset the indicator after servicing, especially if you’re performing routine maintenance yourself. Although the official Owner’s Manual for the 2009 E-350 doesn’t explicitly detail how to reset this light, there is a straightforward method to dismiss it and ensure it’s not nagging you unnecessarily.
This guide provides clear, easy-to-follow instructions to reset the service indicator on your 2009 Mercedes Benz E350 sedan, allowing you to manage your car’s maintenance reminders effectively.
Simple Steps to Reset the Service Indicator
Here’s how to reset the service indicator on your 2009 Mercedes Benz E350:
-
Vehicle Preparation: Begin by getting into your Mercedes Benz E350 and ensuring all doors are completely closed. This is a crucial first step for the reset process to function correctly.
-
Ignition Position 1: Insert your key into the ignition switch. Turn the key to position 1. It’s important to stop at position 1; turning to position 2 will start the engine, which is not what you want at this stage. Position 1 usually turns on the car’s electronics without starting the engine.
-
Accessing the Display: Look at the instrument cluster display. If the temperature/mileage display is not currently visible, use the menu selection buttons located on the left side of your steering wheel to navigate to it. These buttons, marked with rectangle or “window” graphics, allow you to cycle through the menus on your display.
-
Initiate Reset Sequence: Locate the ‘Reset’ button. This is a small black plastic spindle situated on the left side of the frame surrounding your speedometer and menu array. Once located, press this Reset button quickly three times. A brief, rapid press is key; avoid pressing and holding, as holding it down will reset the trip odometer instead. After pressing three times, the screen should display “UB: 11.9V” or a similar voltage reading, indicating the start of the reset sequence.
-
Navigate to Service Menu: Press the down-arrow button, which is the sub-menu button on the left side of the steering wheel, just once. This action should bring up the ‘Service Menu’ on your display.
-
Select ‘Confirmation’: Now, use the “+/- Selection Marker” buttons located on the right side of your steering wheel. These buttons allow you to scroll up and down through the sub-menus. Scroll through the options until you highlight ‘Confirmation’.
-
Enter Confirmation Menu: On the left side of the steering wheel, press the right-hand button (Next Menu button). This will take you into the ‘Confirmation’ menu that you just selected.
-
Choose ‘Full Service’: Again, use the “+/- buttons” on the right side of the steering wheel to navigate through the options within the ‘Confirmation’ menu. Scroll until you find and highlight ‘Full Service’.
-
Confirm Service: Finally, press the right-hand button (Next Menu button) one last time. After this press, your display should change to read “Service Confirmed.” This confirms that you have successfully reset the service indicator.
-
Exit the Service Menu: To exit out of the service menu and return to the standard display, press the “Previous Menu” button (left-hand button on the steering wheel) several times. Keep pressing it until you have navigated completely out of the menu options and are back to your regular display.
It might take a short period of driving after resetting the indicator for the service message to completely disappear. Don’t be alarmed if it doesn’t vanish immediately; it should clear after a brief drive cycle.
Important Notes for Mercedes Benz E350 Service Indicator Reset
- Menu Buttons: The rectangle (Menu) buttons on the steering wheel are used to switch between main menus – use them to go to the next or previous menu as needed.
- Sub-Menu Selection: The “+/- buttons” are specifically for selecting sub-menus once you are within a main menu like the ‘Service Menu’.
- Navigation Arrows: The arrow buttons, specifically the up and down arrows, are used for navigation within a sub-menu to choose specific options like ‘Confirmation’ or ‘Full Service’.
While these instructions are tailored for the 2009 Mercedes Benz E350 sedan, similar methods might apply to other models within the same E-Class generation. However, always refer to your vehicle’s specific manual when available for other maintenance procedures.
By following these steps, you can effectively reset the service indicator on your Mercedes Benz E350 2009, keeping you informed about your vehicle’s maintenance schedule without unnecessary dashboard warnings. Remember, resetting the indicator is useful after maintenance, but it’s crucial to adhere to the recommended service intervals for the longevity and performance of your vehicle.
