That light indicates that you have probably exceeded a certain mileage for having factory-recommended service done such as a new timing belt, air filter, plugs, ect.Take a look at the mileage on your odometer and compare that to the service intervals in the owners manual.The dealer knows how to reset the light after the required work is done. If you do the work yourself, this won't reset the light. I'm sure there are some good Honda people here who can tell you how to do that.
