also, just in case OP isn't aware, the adaptive cruise is separate from the lane keep assist. the green steering wheel is the lane keep assist. you can turn it off with the tiny button on the tip of the turn signal stalk. i've had decent luck with keeping adaptive cruise running longer than lane keeping. you can use them both or together or separately. also, make sure that in your settings you set the cruise control to adaptive, not intelligent. intelligent will adjust your speed to match speed limit signs--however mine things highway signs in utah are speed limit signs and will drop my speed all the time.
