Exhaust brake.

Is it advisable to engage it even when not towing? Does it affect mileage?

My wife calls it the fart button.

You don't need to be towing to use it. I use it all the time. It just helps you decelerate.

Yes!! ^ Haha my uncle has a DPF delete on his 2012 Cummins. Man does the exhaust break sound awesome! Works very well when slowing down with a trailer too

How does it sound? I don't hear anything, i'm probably deaf.

When i press it once, its icon on the dashboard turns yellow and when i press it the 2nd time it turns green. What does those colors represent?

With a stock exhaust it sounds like a quieter version of this:
