How to reset the maintenance light on a BMW X3?

I just bought a slightly used BMW X3 and I noticed that the maintenance light is on. How do I reset it so it's back to factory settings?

To reset the maintenance light on your BMW X3, first turn on the ignition without starting the engine. Then, press and hold the odometer button until the maintenance light flashes. Release the button, and then press and hold again until the light resets. This should reset the maintenance light and restore it to factory settings.

Another option is to use the iDrive system on your BMW X3. Go to the 'Vehicle' menu, then 'Vehicle status', then 'Service required'. Here, you can reset the service interval or the oil change interval.
