You can push it anytime.
It resets every key cycle so you have to push it again.
On flat ground pulling light loads it will hurt your MPG since the trans stays in a lower gear.
I pull a 10' cargo trailer and use mine on long down hills to slow down using engine braking. If I want to coast down the hill, I turn it off and let the motorhome "loose" to gain (or maintain) speed.
I'll sometimes push it on at the bottom of a hill to get a "jump" on the hill climb ahead. That way I go into the uphill in a lower gear.
You should use it like you would if you were downshifting a manual transmission. When on, the truck downshifts sooner & it helps hold the truck back on hills. It also allows you more power (when on) to climb hills. 99 miles out of 100 mine is off and I travel east TN and western NC. We have some hills!
Play with it some, you can't hurt anything, well,,,, unless you push it when you're doing 150 MPH. You might want to stay in high gear then ;)
