Those are great questions, Bill. Our team looked into your VIN and it doesn't appear to have AFM or DFM. Please know, we take the personal and private information of our customers seriously, and we don't recommend posting your full VIN publicly. As for Auto Stop, some vehicles have a button to turn Stop/Start off for one ignition cycle. If the vehicle is equipped with the Stop/Start deactivation switch, you can push the switch to turn off Stop/Start. Stop/Start is turned off when the LED indicator on the switch is not illuminated. If you have any further questions, please visit https://s.chevy.com/support-request and fill out the support request form with all pertinent details. This form helps our team gather the right information and ensures your request is routed appropriately.
