That's a light I never like. But it could be a simple fix. Tighten the gas cap. If the car senses something isn't right in that area on comes the emissions light. It can take a couple of trips back and forth to work or the store after you tighten it before the light turns off. Please don't over tighten it. There should be instructions on the cap or in that area, such as 'tighten until it clicks' or such.


If it's the original gas cap, consider replacing it. You should be able to get one at the auto parts store. Just make sure the cap is designed to fit your car. If it doesn't fit correctly your car will still sense something is wrong and that light will stay on.
