Ive worked a few things out with the Stilo:-
1) Seat belt reminder comes on if i go over 5mph, or drive and dont wear it for over 10 seconds.
2) Doors auto lock at about 10mph
3) City steering disengages at about 18-20mph.
2) Is a setting in you're menu that you can turn off and on. It's 20km says in manual I think =p. I have it on just to scare someone who gets in the car. My mum as like wtf was that
3) Didn't know that feels the same all the time, turned it off when was going 120 or so on way back from Ipswich on saturday night
