I found if u go into settings on the main console, you can programme up to 6 different s speeds, then once programmed you can select them by pressing mem on the steering wheel, it's quite crap and alot of effort, probably not one of the selling points of the car lol
When in Vehicle parameters, set all your speeds into MEM then when driving with Limiter or Cruise Active press and HOLD the - or + on the steering wheel, this will tab up or down to the next Memory value.
If you set speeds of 30, 40, 50 70 and 85 you have them all virtually. Just press and hold and the MEM kicks in.
Hi you may have already sorted this out, but just incase, here goes:1 Go into the menu until you get the boxes up with the preset speeds in.
2 On your steering wheel, right hand bottom wheel turn this to hi-light box with speed in (Dotted border on box)
3 Press wheel (dotted border then changes)
4 Turn wheel up or down to desired speed
5 Press OK (on Dash)
6 Repeat for all other speeds
