On the LEAF the cruise control is separate to the digital speedo, depending which model you have, you will either have a standard cruise control or Propilot.
Using propilot, the speed setting is shown on the top right of the screen with a small digital read out and can be adjusted up and down using the + / - set button. If the vehicle in front slows down, then that digital figure reduces, it won't go over that pre-set figure unless it is overridden by pressing the accelerator pedal and will indicate this by flashing until the speed reduces to the pre-set figure.
I have never used a LEAF with the standard cruise control, so unable to say, but assume something similar, perhaps somebody with a standard cruise control can help out here.
Thanks very much again, I have the Connecta so no pro pilot. Will try it out next time we drive. I can’t possibly imagine you would have to set the speed against the needle speedo.
incidentally, the “status” screen picture in my manual doesn’t show the digital speedo, only radio settings.
