1) remove your gas cap. 2) put it back and make sure you hear 4+ clicks when tighten gas cap. 3) it should automatically correct itself if your gas cap is air tight; if problem occurs again. you might need a new gas cap.
vsc stands for vehicle stability control. and the light thats on is indicating to you that the vsc is turned off, so you need to turn it on which i recomend doing for everyday driving and the button is located in the centre consol very near the heated seat buttons.
