In this video, we will see how to reset the maintenance light of the 2017 Mercedes CLA: turn on the instrument panel, quickly press the "phone" button on the left side of the steering wheel: immediately after, press and hold the "ok" button in the center of the steering wheel for about 3/5 seconds.

At this point, a menu will appear on the dashboard, which we will navigate with the "up/down" buttons on the left side of the steering wheel.

Look for the "assyst plus" option and confirm with "ok". Within the "service" menu, select "maintenance" and confirm: we will be asked to confirm the reset: answer "yes" and confirm. A message like "maintenance completed" or the date of the next service should appear.

Turn off the instrument panel and restart the vehicle for verification.
