Going to hijack this thread a bit because I see this question a lot.
@KRon9997 knows this already, but for those confused…
Automatic Ford vehicles often have a feature called “Low mode”. Low mode changes the fuel delivery rate, engine compression, and the transmission behavior to dramatically increase engine braking (and on hybrids it dramatically increases battery regeneration). Low mode serves the same purpose as compression braking (aka: Jake Brake) on diesel engines—gives you improve control of your vehicle while going down hills.
As
@907Ford mentioned… on the Bronco that Low mode has been replaced by Manual mode. Which gives you a lot more control over how the transmission behaves when compared to Low mode. 100% awesome if you have a rough understanding of how transmissions work, but if you’ve only driven an automatic transmission it’ll take some practice.
And unlike Low mode, which is primarily used for going down hills… Manual mode can be used in a bunch of different situations. For example, if you combine Manual mode with Trail Control it gives you a ton of control over the vehicle while off-roading at slow speeds.
Those of you with the manual transmission Bronco obviously don’t have Manual mode because you already have complete control over the transmission. Because of that you also don’t have Trail Control. BUT, you do have something called Hill Decent Control. Very similar to Trail Control… except it only is suitable for going down hills.
