I found this great picture of the display you will see on your new C-7 for the first 500 miles. It lets you know that you should take it easy for the first 500 miles while all those moving parts are getting to know each other.
Here's a video showing the exact change (at 500 miles), when the recommended maximum RPM increases to 4,500 from 6,500.
