Just to note, make sure you know what your HDC is set at when you engage it. If you're inching down a hill in 1st gear at 3 mph and you decide to switch on the HDC and it's set for a higher mph, you are going to accelerate and possibly panic. Been there done that! Now my HDC is set at 2.5 mph and I can dial it down further in action using the - (cruise control) button on the steering wheel. Worked great going down a steep icy hill.
