Meanwhile, back in NewCar Land… thanks, Rene. The steering wheel button route works perfectly. Moreover, can turn off the auto-broking and stop/start in the same way, at the same time. Next search is for screen-free way to turn off the squidgy traction control and engage the sport setting.
Another question… the computer sez it wants me to download new software. It that safe? Only reason is that whenever I do this with Windows, it ends up with something not working. How long does it take?
