Yes, there is a distinctive sound from the parking break motor that I hear engaging. I only hit the switch one time while moving at moderate speed, as it didn't quite sound that healthy, but noticed that it noticeably started slowing the car while I heard the thump-thump-thump of the parking break going on and off (almost like the sound of anti lock breaks kicking on, but not as powerful of a stop and sound / drag was coming from the back wheels only). Here is their page on it: https://www.fordservicecontent.com/Ford_Content/vdirsnet/OwnerManual/Home/Content?variantid=6952&languageCode=en&countryCode=USA&Uid=G2122058&ProcUid=G2122060&userMarket=usa&div=f&vFilteringEnabled=False&buildtype=web https://www.fordservicecontent.com/Ford_Content/vdirsnet/Own... Also, if I put it in gear and step on the gas, the parking brake automatically releases (you hear the whir of the motor releasing the brake). Something else -- if it is running in drive and stopped, and you open the door and take your foot off the brake and get out of the car, it automatically shifts into park too. Triggered by engine running, while foot on brake, if you take the seat belt off and open the door and take foot off brake it returns to park.
