Hi all I have a question and hope someone can answer. I was towing my travel trailer last weekend. Went up to Mt Mitchell camping in NC. I had tow haul mode on and when I was going down the mountain I noticed the engine brake was on. I did not manually set it.
Is it supposed to come on automatic when you are in tow haul mode?
I don’t think it comes on in tow/haul, you must have touched the button. It’s pretty sensitive. One touch full, two touches is automatic mode, it is separate from tow/haul completely as far as I know.
On my 2016 6.7, tow haul mode included engine brake and changing gears. On my 2017, I hit the tow haul button to regear then hit engine brake button to engage that part.
