Understanding the “Service G” Light

The “Service G” light on your Mercedes-Benz dashboard is a reminder that your vehicle needs routine maintenance. This light usually triggers based on mileage or time intervals, indicating that it’s time for an oil change, filter replacement, or other essential services. Ignoring this light can lead to potential engine problems and decreased vehicle performance.

Method 1: Resetting via the Instrument Cluster

This method is commonly used for Mercedes-Benz models equipped with a digital instrument cluster:

1. Turn the ignition key to position 1 (ON) but do not start the engine.

3. While holding the “OK” button, turn the ignition key to position 2 (START) and hold it for a few seconds.
4. Release the “OK” button.
5. The instrument cluster will display a message indicating the service light has been reset.

Method 2: Using a Diagnostic Tool

For more complex models or if the instrument cluster method doesn‘t work, you can use a diagnostic tool:

2. Use the tool’s software to navigate to the service light reset function.
3. Follow the on-screen instructions to reset the service light.

Method 3: The “Old-School” Method

For older Mercedes-Benz models without a digital instrument cluster, you can use a manual reset method:

1. Start the engine and let it idle for a few minutes.
2. Turn the ignition key to position 0 (OFF).
3. Press and hold the “Reset” button on the instrument cluster.
4. While holding the “Reset” button, turn the ignition key to position 1 (ON) and hold it for a few seconds.
5. Release the “Reset” button.
6. The service light should now be reset.
