Enabling Pilot Assist and Adaptive Cruise Control

[IMAY2023]

There are three different functions and all work together,. 
Stop and GO is part of ACC and PA.  The PA and ACC minimum speed is 30kmph and Stop and GO is only activated when ACC or PA is activated. 
You are talking about Stop and GO but it still needs a lead car to fallow.  I Have VW 2019 and it's exactly the same as VOLVO. minimum speed is 30kmph.
