Your advice was exactly in line with a document I later found on the (a?) Volvo web site - which seems to be wrong for the car in question. Not by much but by enough to be confusing.

I assume that there must also be some sort of emergency handbrake release option for an immobile vehicle. Is an auto box parking lock still a thing on "modern" cars? If so presumably there is some way of disengaging that as well.

I would have dived into the car's manual in more detail with such questions but with Son-in-Law about to turn up by the time we had established there seemed to be no way it would start, I thought it best to leave things to him. Driving an E class with Ad-Blue he at least has some exposure to the ins and outs of the stuff. Possibly the previous XC90 also had Ad-Blue but I'm not sure. That was a 2017 model.

I wonder what happens if the level is assessed to be too low - perhaps to an incline on the road being used at the time - as one sits in traffic on the way to obtain a refill? Does the Stop/Start system stop and not restart in mid journey?

There is potential for completely illogical operation in this technology. Too clever for many of its users. And itself.
