Read the manual about those features to get an idea what they do. Then you're going to have to experiment with the settings a little. I find that using the +/- to put in 5, TH on, and EB in green auto works best for me with a 9,000 lb trailer going from Sacramento, CA to Boise, ID. Sacramento is near sea level and the rest of the trip is going up to 7200 ft and then around 4500 ft with little straight and level. Coming down from 7200 ft to sea level I don't touch the brakes at all, the trans and eb work great keeping the speed around 60 and the trans going between 5th and 4th. Settings are different on flat lands. Don't be afraid to try some experimenting.
