In auto mode, the EB does not come on when I let off the accelerator which I do like since I generally coast when I can which conserves fuel. I generally use the EB to hold a certain speed(which is what auto mode was made for per the owners manual) rather than slow me down(which is what full mode was made for per the owners manual). Although I have used full mode to slow me down a few times. I generally don't like full mode always on when driving or towing because it slows me down too much which makes me loose my momentum and I have to waste more fuel to get it back.

Different strokes for different folks I guess. I will say that one of my favorite features of the EB in auto mode is when the truck knows the speed when you let off the accelerator last and it will automatically kick in the EB to not go above that speed. I did not know it had the feature and it surprised me going down a hill once. I let off the accelerator at 60 mph going and I did not have it on cruise control. My speed went to 62 mph going down the hill and I was about to apply the brakes when the EB kicked in to slow me back down to 60 mph. It automatically applied full or partial EB (depending on what I needed) as I was going down the hill to keep me at that speed without me doing a thing. I knew it did that with the cruise control on, but now with it off.

I wouldn't set it in full(orange icon) exhaust brake. I think auto(green icon) is much better to keep on while you drive. I only set it on full exhuast brake when I want to slow down since it kicks in everytime you let off the accelerator. In auto mode it only kicks on when I apply the brakes, go over my cruise control speed, or go over the last speed that I was at when I let off the accelerator.

I think Shiner is just illustrating that when he predicts a situation where he will be continuously decelerating or needs to aggressively decelerate without brake actuation, full-on tends to be better for that. I personally just stick with green and lightly press the brakes to activate the EB in auto mode when I need it.

"It will automatically go to full exhaust brake on start up when hooked to a trailer"

That's something I did not notice. I will have to check when I finally get to tow the new MS.

It will automatically go to full exhaust brake on start up when hooked to a trailer. I always use full exhaust brake and tow haul whether towing or not. I live 30 miles from Branson, and driving these hills and curves for 20+ years, you will learn to dive around here without using your service brakes.

I would set the trailer brake to the proper mode before leaving. Light/Heavy electric or electric over hydraulic. Set gain to 7 and adjust from there.

Report back!

x2. You definitely want to set the exhaust brake to full (yellow icon on dash) while towing. I actually use mine on full almost all of the time because it works great driving solo in the city too.

You will be pleasantly surprised at how effortlessly it tows!
