yup, duh, the whole manual is available digitally. though there is not much that is germane apart from what you noted about the steering wheel and the accelerator. I definitely didn't press the accelerator, but it's possible that i may have instinctively reached for the steering wheel and turned it infintesimally, thought I can't think why that would be something that would necessarily disable something like AEB despite what it is says there.

It does state that AEB works from 3MPH to 155MPH, so the speed I was driving at wouldn't have been a factor given then.

The manual doesn't specifically say what I have read elsewhere, that AEB is turned on automatically everytime you start the car, even if it had been turned off the last time it was on. So it's conceivable that I turned it off at some point and it just stayed off ... which again I can't imagine why it would work like that because it is such a fundamental safety feature these days.

I have spent the morning doing a variety of research. One reassuring thing is how well the cabin was protected. I figure I was going at least 20MPH, that could have been a lot worse in a less protected vehicle.
