This applies to nearly all mustangs with digital odometers... it is a test mode that the dealership uses to test the car as soon as they get them.
Here is what you do...
1: Turn off the engine and take out the key
2: Press the little knob that comes out next to the odometer and keep it down
3: Start up the car and you are now in test mode.
You can test the gauges and run it through all the tests that dealerships put it through. To turn it off, just turn off the engine.
