i have not been able to set smart cruse control so it will maintain a set distance from the car in front. there are no codes when they test for automatic emergency breaking. regardless the scc works but does not autonomously slow down or speed up.

You should contact the Service Department and speak with a technician or easier yet, stop by a dealership and the Service Technician will show you how to set up. Hope this helps.

You must have it recalibrated at the dealership there might be a problem

You should speak to your local dealership. I doubt you'll get decent help posting such questions to the corporate office location in Google Maps.
