2. Reasons To Reset The Mercedes Service B Reminder

Why should you reset the service B reminder on your Mercedes? Resetting the service B reminder is essential for several reasons.

2.1 Clear Dashboard Notifications

How does resetting the service B indicator help declutter your dashboard? The primary reason is to clear the dashboard notification. Having a service reminder constantly displayed can be distracting and annoying. Resetting the system removes the notification, providing a cleaner, less cluttered dashboard.

2.2 Accurately Track Future Maintenance

This simple task can be performed at home with a few easy steps, giving you control over your vehicle’s maintenance schedule.

3. Step-By-Step Guide: Mercedes Service B Reset

How can you reset the service B light on your Mercedes E350? Follow these detailed steps to reset the service B reminder on your Mercedes E350:

3.1 Preparation: Getting Started

What do you need to prepare before resetting the service B light? Before starting the reset procedure, ensure you have the following:

• Your Mercedes-Benz E350: Make sure your car is parked safely.
• Key Fob: You will need your key fob to turn on the ignition.

3.2 Step 1: Ignition Activation

How do you properly turn on the ignition without starting the engine?

1. Enter your Mercedes E350 and insert the key fob into the ignition slot or, if equipped with keyless start, press the Start/Stop button once without pressing the brake pedal.
2. This will turn on the vehicle’s electrical systems without starting the engine. The dashboard lights will illuminate, indicating that the system is in accessory mode.

Why it works: This step is crucial as it allows you to access the vehicle’s service menu without starting the engine. Starting the engine will prevent you from accessing the necessary settings.

3.3 Step 2: Accessing the Service Menu

How do you navigate to the service menu on your Mercedes E350?

1. Locate the steering wheel buttons: Identify the OK, Back, Home, and Arrow buttons on your steering wheel.
2. Navigate to the mileage/trip screen: Use the Arrow buttons to scroll through the instrument cluster menus until you find the screen displaying your vehicle’s mileage or trip information.
3. Press and hold the Home button and the OK button simultaneously for about 5-10 seconds.
4. The hidden Service Menu will appear on the screen.

Why it works: This combination of buttons unlocks the service settings, which are typically hidden from regular use. Holding these buttons down for a few seconds ensures that the system recognizes the command and displays the service menu.

3.4 Step 3: Selecting the Service Option

How do you choose the correct service option in the menu?

1. Use the Arrow buttons to navigate through the service menu options.
2. Look for Assist Plus or Workshop menu options and press OK to select.
3. Select Full Service and press OK.
4. Confirm the service by selecting Confirm Full Service and press OK.

Why it works: This step directs the system to the section where you can confirm the completion of a full service, allowing you to reset the service B reminder.

3.5 Step 4: Confirming the Service B Reset

How do you finalize the service B reset?

1. After selecting Confirm Full Service, the system will ask you to confirm the service.
2. Select Yes and press OK to confirm.
3. If prompted, choose the appropriate oil grade for your vehicle (e.g., 229.51, 229.52) and press OK.

Why it works: This final confirmation step tells the system that the service has been completed, resetting the timer for the next service interval. Selecting the correct oil grade ensures that the system accurately tracks the maintenance requirements for your specific vehicle.

3.6 Step 5: Ignition Reset and Verification

How do you ensure the reset was successful?

1. Turn off the ignition by pressing the Start/Stop button once.
2. Wait a few seconds, then restart your car to verify that the Service B reminder is no longer displayed on the dashboard.

Why it works: Restarting the car allows the system to refresh and recognize that the service reminder has been reset. If the reminder is gone, the process was successful.

What if the service menu doesn’t show up when you press the buttons?

• Solution:
  • Ensure you are holding the correct buttons simultaneously. It should be the Home button and the OK button.
  • Make sure the vehicle is in accessory mode (ignition on, engine off).
  • Try the process again, holding the buttons for a slightly longer duration (up to 15 seconds).

4.2 Issue: Reset Fails to Confirm

What if the system won’t confirm the service reset?

• Solution:
  • Verify that all required Service B maintenance tasks have been completed. The system may not allow the reset if it detects that the service is not actually done.
  • Ensure that the vehicle is in the correct mode (accessory mode).
  • Try disconnecting the battery for a few minutes and then repeat the reset process.

4.3 Issue: Reminder Reappears After Reset

What if the service B reminder comes back after you’ve reset it?

• Solution:
  • Double-check that you selected the correct service interval and oil grade during the reset process.
  • Ensure that the system has fully registered the reset by turning the ignition off and on again.
  • If the problem persists, there may be an underlying issue with the vehicle’s system that requires a professional diagnosis.
