If it was done on its own and not at the dealer, the maintenance light can be reset.
To do this, you must click the "0.0/SET" button on the dashboard when the ignition is off. Hold it down, turn on the ignition (do not drive the engine). The service LED is reset to zero. Press the "0.0/SET" button to press the button to the left of the button and hold it for 15 -20 seconds. Turn off the ignition.
