How do I reset a flashing -22d on my instrument panel ? I do my own oil changes.

What is your question?

I perform my own maintenance where possible because nearest Mercedes Benz Dealer is 90 miles away.Spoke to Mercedes Benz rep.He told me that it was a service Reminder for changing oil and filter . But could not tell me how to reset the flashing -22d because dealership did not perform maintenance. I have 8000 miles on vehicles Oil was changed at 4000 and again and 8000.Need to know reset warning light.

What makes this problem better or worse?
