Are you tired of seeing the service indicator nagging you every time you start your 2009 Mercedes E350? It’s a common issue, and while it’s essential to keep up with your Mercedes’ maintenance schedule, sometimes you need to reset the indicator yourself, especially if you’ve performed a service and the light hasn’t gone off. The owner’s manual for the 2009 E350 doesn’t provide instructions for this specific reset, leaving many owners searching for a solution. After trying various online methods, we’ve compiled a straightforward guide that has proven effective for resetting the service indicator on a 2009 E350.
This guide will walk you through the steps to manually reset your service indicator, allowing you to clear the message from your dashboard. Please remember that resetting the indicator does not replace actual vehicle maintenance. It’s crucial to adhere to your Mercedes-Benz service schedule for optimal performance and longevity.
Step-by-Step Guide to Resetting Your 2009 E350 Service Indicator
Here’s how you can reset the service indicator on your 2009 Mercedes E350 sedan:
- Vehicle Preparation: Begin by getting into your 2009 E350 and ensuring all doors are completely closed.
- Ignition Position 1: Insert your key into the ignition switch and turn it to position 1. This is the position right before starting the engine. Do not turn the key to position 2, as that will start the engine.
- Accessing the Display: Look at the temperature/mileage display in your instrument cluster. If it’s not currently showing, use the left menu selection buttons on your steering wheel (these are the buttons with rectangle or “window” graphics) to navigate to this display.
- Initiate Reset Sequence: Locate the Reset button. This is a small black plastic spindle situated on the left side of the frame around your speedometer and menu display. Press this Reset button quickly three times. The instrument cluster screen should then display “UB: 11.9V” (or a similar voltage reading). Be careful not to press and hold the button, as this will reset your trip odometer instead.
- Enter Service Menu: Press the down-arrow button (the sub-menu button) located on the left side of your steering wheel once. This action will take you to the ‘Service Menu’ within the instrument cluster display.
- Navigate to Confirmation: Use the “+/- Selection Marker” buttons found on the right side of your steering wheel to scroll through the sub-menus. Navigate downwards until you highlight ‘Confirmation.’
- Access Confirmation Menu: On the left side of the steering wheel, press the right-hand menu button (the ‘Next Menu’ button). This will enter the ‘Confirmation’ menu you just highlighted.
- 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 Service: Finally, press the right-hand menu button (the ‘Next Menu’ button) one last time. After this step, your display should briefly show “Service Confirmed.” This indicates that the service indicator reset has been successfully initiated.
- Exit the Menu: To completely 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 options.
After completing these steps, it might take a short drive for the service message to completely disappear from your display. However, this procedure should effectively reset the service indicator on your 2009 Mercedes E350.
Important Notes for Navigation:
- Menu Buttons (Rectangle/Window Graphics): These buttons on the left side of your steering wheel are used to switch between main menus. The rear-ground graphic button typically selects the “next menu,” and the foreground one selects the “previous menu.”
- +/- Buttons (Selection Markers): Located on the right side of the steering wheel, these buttons are used to navigate up and down within sub-menus or settings options.
- Arrow Buttons: These buttons, also on the left side, are used for navigation deeper into sub-menus and for selections within those menus.
While these instructions are specific to the 2009 E350 Mercedes-Benz model, similar procedures may apply to other Mercedes models from this era. Always consult your owner’s manual for general navigation and settings information, even if it lacks the specific service indicator reset instructions. Remember, this reset is for the indicator light only and doesn’t replace professional servicing. Keep your 2009 E350 running smoothly by maintaining its recommended service schedule.
