On the instrument panel of the Smart 451, the Service light that appears can be reset by holding down the button located on the left side of the instrument panel. While holding it down, you will need to insert the ignition key into the appropriate slot on the central tunnel and turn it. This will turn on the instrument panel and you can continue to hold down the button: after a few seconds, you will see that the maintenance light will turn off completely.

To verify that the reset has been successful, simply turn off and turn on the instrument panel.
