Help with '04 turbo conv. warning light

My daughter has a 2004 turbo convertible and we don't have a manual for it. This morning a yellow light in the upper right side came on that is yellow and shaped like the outline of the car and it looks like it has a key in the center of it. Does anyone know what this means? Thanks.

this is the fuel filler cap not properly closed light.
tighten cap, close hatch, restart car, and light should go off when vehicle goes through check cycle.
good luck

That did the trick. Thanks.
