Enabling Pilot Assist and Adaptive Cruise Control

[CjewyLV]

I don't use PA a lot but I do use ACC. But don't know why it says speed too low when I want to turn ACC on below 30kmh. And if I hit the traffic jam when ACC engaged, it's slows down automatically to 15kmh and then dings that acc is turned off and I have to take over and stop car myself.
