I stumbled across a eBay advert for Volvo Green Books, and sent message asking if he had any for 140 or 940 models, unfortunately they didn't.
Anyway, I googled a bit more and found quite a lot of info on the Oz Volvo site, loads of downloads of Green Books, Marketing Leaflets for Amazon, 140, 240, 740, & 850 but so far haven't found any 940 on the list.

Great source of info, I’m slowly downloading to my laptop/cloud so I have copies in case the online source suddenly disappears.
