Enabling Pilot Assist and Adaptive Cruise Control

[Partridge]

My OEM configuration (2019 XC90 USA Advance pkg with factory PA2)

Code:

023 CRUISE CONTROL - 04 Adaptive cruise control stop & go, level1
145 TRAFFIC JAM ASSIST - 05 With Traffic Jam Assist, Level 4
238 TOP DAMPING BRAKES - 02 Friction brake actuator with top damping
148 CURVE SPEED SUPPORT - 01 Without Curve Speed Warning, without Curve Speed Assist
312 LANE CHANGE ASSIST - 01 Without Lane Change Assist
314 ADAPTIVE CRUISE CONTROL VERSION - 01 ACC Version 1

I too have attempted adding Curve speed assist.  I can get the toggle for assist, but I can’t get the toggle for warning.  I do not see any change in behavior at all.
