So weird, I don't get it either. I was just noting that it in fact doesn't have them. This means no proximity "indicators" on screen when parking? My lincoln had them all the way around. Does the F150 have this?Without Active Prep, no sensors on 502A. My dealer confirmed firmed with Ford. I don’t think there is anything I can do About it. It actually blows my mind that an XLT has the function and you have to spend $995 to buy stuff you don’t want to get the sensors on a Lariat 502A.
