I have looked on the wife's previously owned 2009 & 2011 CTS and the wife's 2013 CTS for the RPO & Paint Code labels to no avail. I have looked in the glove box, door posts, under the hood, battery compartment in the trunk, spare tire cover and under the insulation/appearance cover on the interior of the trunk lid. Any help would be greatly appreciated. Thank you in advance, - BC

 

its supposed to be on the underside of the spare tire cover .. have you looked inside the wheel well for the spare tire?

The label had not been applied to the spare tire cover. It was laying under the spare tire with the backing on it. I removed the backing and applied it to the cover. Thanks! - BC
