My 2010 Fusion hybrid I traded for the Cmax had an Engineering Test Mode that could be entered at start up. I found out how to do this in the Cmax. When starting hold the ok button on the left of the steering wheel and start the car. In the left panel you will have the test mode which you can scroll with the up and down arrow keys. It has a lot of interesting information in it. If you haven't already tried it you might want to check it out. This mode will exit when you shut the car down.
