2010 C300 - How to reset service message


Can someone tell me how to resent the ASSYST PLUS message regarding Service A?

I have tried the procedure for earlier model years, but apparently the system was changed in 2010 because the displays are different and earlier instructions don't work.

Thank you.

I found that if I reset it before it was due all went well. When I waited until it was overdue I had to have it reset by the dealer.
