I'm not sure wht you're referring to. We need to define terms.Dosent yours have the hill assist option?
"Hill Start Assist" (according to my Owner's Manual) helps when starting off going up an incline; it keeps the brakes on for a short time until you have a chance to press the accelerator -- so you won't start rolling backwards (even with an automatic transmission). I love that feature, since we have a rather steep driveway.
"Hill Descent Control" (HDC), which controls the vehicle's speed in 4WD Low, when descending a steep offroad hill? It's meant for literal crawling down a hill; I do use it occasionally.
But I was talking about manual shift, where you click the gear lever to the left and it will maintain the gear you're in, until you manually change it. I'll use that occasionally when going downhill on long moderately-steep stretches of roads (paved or not), to maintain speed and prevent using the brakes by not have the auto transmission shift up. Speed is higher than crawling in HDC.
