RAM Cummins Exhaust Brake - Auto vs Full

Just purchase a brand new 2019 RAM 2500 with Cummins diesel. The Owners Manual states nothing about how this works. Doesn't explain Tow/Haul Mode either. Thank goodness for wonderful people like you for taking the time to put these videos together. THANK YOU!!!

Another great video Marion- Always informative. A few people said it already but I think you will love the auto EB in the hills. I use it all the time empty or pulling my 5th wheel. Keep the truck at whatever speed it is at when I take my foot off the accelerator. Keeps you from going back and forth or riding the throttle

Another great video with lots of good info, just picked up my 2018 Ram 2500 last week. Thanks for the video Mr. Blair.

Thank you, Marion. Always informative.

Liked this video A lot, so well demonstrated and explained. Nice....very nice, even discovering it after 6 years, thanks.

Great explanation of the auto vs. full mode. Thanx!!!

Use the Auto mode when traveling on roads and highways and when you come up on a town or city that you have to drive through the Jake brake is used when you just touch the brake peddle to help you slow your truck down. The Full Mode is also to help you slow down BUT you don't need to touch the brake for it to activate. I have a 2018 RAM 2500 Tradesman 4x4 and pull a 10000 LB 5th Wheel and I love that I have those Jake brakes. I drove to Pigeon Forge Tenn, and on those hills the Full exhaust brake it sure did help me not having to use my Brake so much that they get hot and we all know what can happen if the brakes get to hot. Thank you for all the information you share. I like how you explain everything for us to understand. I like gages too cause I haven't had a gage lie to me once.

Great explanation/demo! Just bought a 2019 and didnt understand the difference. Thanks for taking the time to put together.

Hi, Marion!  I really enjoy your videos!  Thanks for sharing!

I have towed my 12,000 lb fifth through the Rocky Mountains many times using the automatic exhaust brake and I love it. Going down you very seldom have to touch the brakes as the exhaust brake maintains your current speed when you release the throttle .

Thank you Marion for another great video!

For what it’s worth my mechanic told me that running the full exhaust break helps keep the VGT cleaner and working properly. It also saves your breaks. My 2018 Ram Cummins has had several upgrades done which eliminated the majority of the typical problems stock trucks have.

Great video it answered my questions regarding exhaust breake

Im been drive in dodge diesel for almost 10 years,and I have to said I am a complete ignorant, great information Sr

auto mode with tow haul is how the system wants to be. here in California the auto mode holds the speed and also applies when using the brakes. the auto mode is subtle without a load. we have a 14k 5th wheel and you can tell the difference between full on and auto modes with the trailer going down steep grades

This is what I have been told: "Every time you get in your truck to drive it, turn on the exhaust brake and the tow haul mode. It lets your veins in your charger actuate a lot more and will keep you from replacing a turbo. I was having issues with mine and saw this on a forum and it corrected the issues before it was too late."

Me gusta como explica todo paso por paso y lo demuestra con echos muy buen video Mario saludos de dinuba ca 👍🏽

Another fine production Marion. You're videos are a huge benefit to Ram owners. Living in California, I felt a little bad for you trying to film this demo without even the hint of a hill! I've recently discovered a function of the cruise control that I've never experienced before. Here's the scenario: Driving at freeway speed with cruise control on, no exhaust brake, no tow mode, and empty. When descending a hill, the truck will automatically downshift to maintain speed setting. I have not experimented with this phenomenon while in tow mode, or with either exhaust mode. I do however find it to be a little annoying. Probably because I'm not used to it. Perhaps (when using cruise in our hills), I should have the exhaust brake in "auto" mode. I suppose that way it would use the exhaust brake before having to downshift. ( I hope I made sense of that whole explanation...)

I use Auto all the time when in the mountains. When you are coming down a grade, the exhaust brake toggles on and off to maintain whatever speed you were traveling when you took your foot off the accelerator. It is wonderful for that as opposed to the full brake which will really slow you down below your desired speed. You will gain a huge appreciation for it on your trip to Colorado.

Just used it pulling my travel trailer down Loveland pass on Colorado. Auto is amazing.
