I wouldn't be worried about it at all. The check engine light can come on for the gas cap not being screwed on tight enough. The check engine light just has to do with emissions, I went to the dealer one night before they were about to close and had them check my car because the light had come on, they told me not to worry and just drive the car as normal.
If you want to read the code without going to the dealer you will need a code reader.
