Thanks for all your input, I understand a bit better now the ''ready'' mode, all be it a little alien.
Although I have been driving for the best part of 60+ yrs, bikes, cars and HGV Europe I am looking forward to my C-HR and gadgets, which only half will be used.
My concern with the battery, which has been reported on here and elsewhere, is the hospital visits that me and my wife have to endure now, so reliability is needed. The reason to move back to Toyota.
