    You probably need to tighten the gas cap, then drive for a while and hopefully the light will go out.

    ditto^^^ and if the cap isn't loose, might you have overfilled the tank?

    Tighten gas cap until you hear ONE click. Not necessary to tighten beyond one click.

    I believe there is a replaceable seal on the gas cap as well. This may be another solution.
