ENG BRK question - 2017 DX3

We're not noticing a difference between the ENG BRK switch when it's up vs down. We're assuming up= HI and down =LO. It does seem to be working, we're just not noticing a difference between the switch positions. Any insight?

On ours, up is high and down is low like you mention. The only time Iíve noticed a considerable difference is when towing heavy and trying to maintain speed coasting down pretty decent grades. Thatís the only time Iíve ever gotten any additional benefit from switching it to high. Itís extremely effective on the low setting.

Yep. My understanding is on low it only uses 3 of the cylinders, so about half as powerful. Its a very slight difference on flat ground but get on a long steep grade and it's definitely noticable.

It might just be me but it seems that in high that it downshifts a little quicker to keep the RPM up to hold back more.

Works best in lower gears and higher RPMs. We came down 11,500 ft Wolf Creek Pass, CO without having to use the brake pedal on our 2018 Dynaquest XL. Engine brake on high, set trans to 4th gear and cruised down at about 40 mph.

I have heard not to use the engine brake on wet roads. I'm guessing it could cause the back tires to slip.

Agree. CDL course notes this.
