Do you have Onstar? If yes, give them a call, they could run a remote diagnostic check and let you know how critical it is.
Owner's Manual says, 'did you recently buy gas?". If yes, it may take several start/shut downs to extinguish the light. Read this section. We reseated the gas cap and it was 2 days before the Check Engine light went off.
Be glad the light is still on....so when you go for service they will see it and be able to check for the respective code. I've had the light come on then go off and the dealer was unable to find a code!!
Disconnect battery to clear the code. If it comes back on, it's a hard code then bring it to dealer.Like the other forum member said probably just a light for a non tighten gas cap. Good Luck.
