On my wife's 2000 Accord the maintenance required light is the light that tells you it's time to change the oil. Now, this may not be necessarly true. If you went to a Jiffy Lube type place to have your oil changed, they may not have reset your light (especially if it wasn't on), so you may not need an oil change. If you do need to change your oil, the Honda dealer (and most other places) will turn off the light when they change it. It's a simple procedure, but I can't think of it right now. Look in the index of your owners manual under "maitenance required light" and it will show you the procedure to turn it off if you don't need your oil changed. BTW, this light is different that the 'check engine' light. That light comes on when a sensor has sensed an irregularity in your engine performance. Most times it's actually the sensor going bad.
