My maintenance required light is red. when we first bought it (used with about 89k) it was green. Then a couple thousand miles, it turned orange and now its red. It now has about 95k. haven't had any major problems with it and i perform scheduled maintenance on it regularly. if i had to guess, i'd say its just something that needs re-set. i refuse to take it to the dealer because they are going to want $100 just to look at it. So if someone could tell me what this means (obviously it means there's maintenace required but why its on) or how to re-set it that would be greatly appreciated.
