"The hill descent control system helps maintain vehicle speed when driving under 15-21 mph(25-35 km/h) on steeper downhill grades. "
Sounds like the target is to keep it under 15mph.
It says that but the few times I used it , it kept it to a MUCH slower speed.
I think that speed may refer to when its ok to turn it on..
