In the manual it does say that you can reset it, but so far I don't think anyone has had any luck doing it. I paid $18 for my dealer to reset mine when it was in for some warranty work. I wish I hadn't paid him, but now it is too late. If I get the "maintenance required" again, I will take it into the dealer and tell them that the procedure does not work as stated in the manual, and that I want it fixed so that the procedure does work.
I hope that if any body does try this tactic, that they would let us know if they were successful.
