Thanks @kezo and @Fastbike1000 I did a bit of googling and found a YouTube video which showed me how to find it in the menus, which I’ve now done. It was on ‘adaptive’ which explains why it was braking at some times (approaching corners etc) but not others. Very clever but disconcerting if you aren’t used to it. It shouldn’t be that difficult to find IMHO. Voice control was no help either. I’ve set it to ‘low’ now so it should be more normal and I’m taking my wife out in it soon so wanted to get it sorted before that! I still can’t find any trip computer settings to check how many miles I’ve done, so have given up on that, which is a shame as I wanted to see how the remaining range compared to miles driven, as that was a disappointment with the 30e, this being a critical consideration. The range was 85% at pick up. The dealer had very kindly collected it this morning from another dealership 35 miles away for me.
