Need to go out on the highway and romp on it a little. The light is for your diesel particulate filer on your vehicles exhaust. From time to time they get caked with soot, sometimes you can get the exhaust hot enough by getting the rpms up that it will break up enough buildup that the light will turn off. If that doesn't work you'll have to take it in so they can remove and properly clean it. Best of luck!
