How do I reset the service indicator on my BMW M7?

I recently purchased a BMW M7 and the service indicator is showing that the next service is due. But my mechanic says it's not necessary. How do I reset the service indicator myself without going to the dealership?

Hannah, the service indicator can be easily reset through the iDrive system. Go to the vehicle info menu, then select service required. From there, select reset and the indicator will be reset. You can also check the manual for the specific steps.
