Experiencing the persistent service indicator on your 2009 Mercedes-benz E-class E350 can be a minor annoyance, especially when you are proactive about your vehicle’s maintenance schedule. While the owner’s manual may not explicitly detail the reset procedure, we, as Mercedes-Benz experts, understand the importance of keeping your dashboard clear and informative. This guide provides a straightforward, step-by-step method to reset the service indicator on your 2009 E350, ensuring you can address this issue effectively at home.
Step-by-Step Guide to Resetting the Service Indicator
Follow these instructions carefully to reset the service indicator on your 2009 Mercedes-Benz E350 sedan. This process utilizes the controls on your steering wheel and the instrument cluster reset button.
-
Vehicle Preparation: Begin by entering your 2009 Mercedes-Benz E350 and ensuring all doors are completely closed.
-
Ignition Positioning: Insert your key into the ignition switch. Turn the key to position 1. It’s crucial to stop at position 1; proceeding to position 2 will start the engine, which is not required for this procedure.
-
Accessing the Display: Look at the temperature/mileage display in your instrument cluster. If this display is not currently visible, use the menu selection buttons located on the left side of your steering wheel. These buttons, identified by rectangle or “window” icons, allow you to navigate through the menus until the temperature/mileage display is shown.
-
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 display. Press this reset button rapidly three times. After the third press, the screen will change to display “UB: [Voltage Reading]V”. Avoid pressing and holding the reset button, as this action will reset your trip odometer instead of accessing the service menu.
-
Enter Service Menu: Immediately after the voltage display appears, press the down-arrow button (sub-menu button) once. This action will take you to the ‘Service Menu’ within the system.
-
Navigate to Confirmation: Now, use the “+/- Selection Marker” buttons located on the right side of your steering wheel. These buttons allow you to scroll through the sub-menus within the ‘Service Menu’. Scroll either up or down until you highlight ‘Confirmation’.
-
Access Confirmation Menu: Once ‘Confirmation’ is highlighted, press the right-hand (Next Menu) button on the left side of the steering wheel. This will display the ‘Confirmation’ menu options.
-
Select Full Service: Within the ‘Confirmation’ menu, use the “+/-” buttons again to scroll through the options. Locate and highlight ‘Full Service’ in the list.
-
Confirm Service: With ‘Full Service’ highlighted, press the right-hand (Next Menu) button one final time. Upon pressing this button, your display should update to read “Service Confirmed.” This confirms that the service indicator reset process has been successfully completed.
-
Exit Menu: To fully exit the service menu and return to the standard display, press the “Previous Menu” button, located on the left side of the steering wheel, multiple times. Continue pressing until you have backed out of all menu options and are back to your regular display.
It’s important to note that it might take a short period of driving after resetting the indicator for the service message to completely disappear. Rest assured, if you have followed these steps correctly, the service indicator for your 2009 Mercedes-Benz E350 should no longer be active.
Understanding Your Mercedes-Benz Controls
To ensure clarity, let’s reiterate the functions of the steering wheel buttons mentioned in this guide for your 2009 E350:
- Rectangle (Menu) Buttons: These buttons, on the left side of the steering wheel, are used to navigate between main menus. The right-hand rectangle button typically selects the “next” menu, while the left-hand button selects the “previous” menu.
- +/- Buttons (Selection Marker): Situated on the right side of the steering wheel, these buttons are used for navigating within sub-menus and making selections. They allow you to scroll up and down through lists of options.
- Arrow Buttons (Navigation): Specifically the up and down arrows, often used for navigating within a sub-menu or list, like moving between options in the ‘Service Menu’.
By understanding and correctly utilizing these controls, resetting your service indicator becomes a straightforward task.
