Alright I dug up my paperwork for ESP and pasted it below so we can all speculate together. The paperwork is from my wife's Escape, as I don't have the ESP paperwork for my Bronco handy (don't even remember if I got ESP tbh). But I am fairly confident it's the same, if it's not... someone yell at me.
But anyway... the full section below...
