Enabling Pilot Assist and Adaptive Cruise Control

[kostik_xc70]

2023 XC60 T8 Ultimate here...And I've reach the end of my google skills.

Mine defaulted to LEVEL 1, and from what I can tell there isn't really a different between level 2 and 3 for my specific vehicle. 

I don't want to mess with this before my road trip coming up, but is there any reason to try level 2 and 3 vs. level 1 for a car that has factory pilot assist?

Thanks.

no
