The service light on a 2021 Mercedes CLA indicates that an oil change is needed. After completing the tasks involved in the oil change, such as replacing the engine oil and oil filter, you need to update the mileage for the next service.

To do this, turn on the ignition and simultaneously press the menu button and the OK button, both located on the left side of the steering wheel. Keep the buttons pressed for a few seconds, and the display will show the menu settings from which you should select the service option using the arrow buttons.

After selecting the "Maintenance Intervals" option, you will access the reset procedure, and at the end, restart the instrument cluster to complete it.
