In the past this site has been really helpful. I have a 90 Acura Legend L.
It's a great car and a lot of fun! It just turned to 129,000 miles today and I noticed my little maintenance required window on the dash panel was changing to yellow instead of green. It's half green and half yellow now. Basically I have heard that it just means take it to the dealership to reset it. And it's really not important. Can you reset those easily yourself? Should I even worry about it? I just want to make sure there's not something I need to maintaine. It's regularly maintained so I am kind of lost for the moment. Any imput would be great! Thanks

It doesn't matter what color the window is, the fact that it is on would mean you have to get it checked out. I don't think you can reset it yourself. What would be the point. If you did that every time it came on, you would never know what the problem is.

Haaaaa!!
So I just wanted to answer my own question, Lol I had asked about the color change on my dash maint. Req window on my Acura Legend. Well the other day I got a oil change done on it. When I got my car back the window was back to green! So I asked the guy how they changed it back, well right under the dash there's a little hole. It is shaped like a key hole as well. You just put your igniton key in it and it turns back to green! How about that! Lol I hope this will help anyone with the same problem. Pretty easy fix:) The window changes color after a certain number of miles are on the car to make you think you need to take it to the dealer, so they can make more money of you. Imagine that! The color scheme goes the same as a traffic light. Peace
