To reset the maintenance reminder on the Mercedes GLA 250, you need to operate the digital instrument panel using the controls on the steering wheel. With the car stationary, engage the parking brake and turn on the ignition without starting the engine.

On the left side of the steering wheel, use the small touchpad and the arrow buttons to scroll through the screens until the main menu with icons appears; from here, select the section dedicated to the onboard computer/Trip. Using the same controls, access the workshop menu on the display: this screen shows options such as vehicle data, roller test, brake wear, and “Assist Plus.” Enter Assist Plus to view the available maintenance items and select the type of service performed, such as “oil service” or “full service.” The system will display the set oil level and ask for confirmation with a message like “Maintenance completed?” At this point, confirm your choice by pressing the OK button on the steering wheel: the system will register that the service has been performed and update the mileage and time interval for the next service.

Once the procedure is complete, you can return to the normal driving screen, and the maintenance warning will no longer appear upon the next ignition, with the service for the Mercedes GLA 250 correctly reset.
