Dealing with a persistent service indicator in your 2009 Mercedes E350 can be frustrating, especially when you’re aware of your vehicle’s maintenance schedule. While the owner’s manual may lack specific instructions for resetting this indicator, there’s a straightforward method to clear the message and regain a clean dashboard display. This guide provides a clear, step-by-step process to reset the service indicator on your 2009 Mercedes E350, allowing you to address this common issue effectively.
Here’s how to reset the service indicator on your 2009 E350 sedan:
-
Begin by entering your 2009 Mercedes E350 and ensuring all doors are fully closed. This initial step is crucial for the system to properly register your actions.
-
Insert the key into the ignition switch. Turn the key to position 1. It’s important to stop at position 1; proceeding to position 2 will start the engine, which is not required for this procedure.
-
Check the instrument cluster display. If the temperature/mileage display is not currently visible, use the left menu selection buttons on your steering wheel to navigate to it. These buttons, identified by rectangle or “window” icons, control menu navigation within your Mercedes system.
-
Locate the reset button. This is a small black plastic spindle situated on the left side of the instrument cluster frame, near the speedometer and menu display. Once located, press this reset button quickly three times. Avoid pressing and holding the button, as this action will reset the trip odometer instead of accessing the service menu. After pressing correctly, the screen should display “UB: 11.9V” (the voltage may vary slightly).
-
Navigate to the ‘Service Menu’. Immediately after the voltage display appears, press the down-arrow button (the sub-menu button) once. This action will take you into the ‘Service Menu’ options within your 2009 Mercedes E350 system.
-
Scroll to ‘Confirmation’. Utilize the “+/- “Selection Marker” buttons located on the right side of your steering wheel. These buttons allow you to move through the sub-menus. Scroll either up or down until you highlight the ‘Confirmation’ option within the Service Menu.
-
Access the ‘Confirmation’ menu. On the left side of the steering wheel, press the right-hand button (Next Menu button). This will select ‘Confirmation’ and display the ‘Confirmation’ menu itself on your 2009 Mercedes E350 screen.
-
Select ‘Full Service’. Again using the “+/-” buttons on the right side of the steering wheel, scroll through the options within the ‘Confirmation’ menu until you reach and highlight ‘Full Service’.
-
Confirm ‘Full Service’. Press the right-hand button (Next Menu button) one final time to confirm your selection of ‘Full Service’. Upon successful confirmation, your display should clearly read “Service Confirmed,” indicating the service indicator reset is complete for your 2009 Mercedes E350.
-
Exit the Service Menu. To fully exit the service menu and return to the standard display, press the “Previous Menu” button (left-hand side steering wheel button) several times. This will step you back out through the menu layers.
After completing these steps, it might require a short drive for the service message to completely disappear from your 2009 Mercedes E350 display.
Understanding the Menu Buttons on Your Mercedes-Benz Steering Wheel
To effectively navigate the service reset procedure on your 2009 Mercedes E350, it’s helpful to understand the function of the steering wheel buttons:
-
Rectangle (Menu) buttons: These buttons, often depicted with window-like icons, are used for primary menu navigation. The right-hand rectangle button typically selects the “next menu,” moving you forward in the menu structure. Conversely, the left-hand rectangle button selects the “previous menu,” allowing you to move backward.
-
+/- buttons: These buttons serve as “Selection Markers” and are crucial for navigating within sub-menus or settings. Located on the right side of the steering wheel, they allow you to scroll up or down through lists of options or adjust values within a selected menu.
-
Arrow buttons: Specifically the up and down arrow buttons, are used for directional navigation within a sub-menu. In this service reset process, the down-arrow button is used to enter the ‘Service Menu’ after the initial reset button sequence.
By following these instructions, you should be able to successfully reset the service indicator on your 2009 Mercedes E350. Enjoy a dashboard free from service notifications!
