Yes as I suspected that is just a supplement. The supplement is sealed in a plastic bag with the full owners manual, so I don't know how they managed to supply one without the other.
This is what I got with my car.

The full manual, about 350 pages, on the left, a quick reference guide in the middle and the model specific supplement that some cars will have. They should have also have given you a wallet to keep them all in as well as a blue cloth for cleaning your touch screen.
You will only have got a spare wheel, jack and brace if you had requested one. Maybe more now, but it was £100 extra in lieu of the puncture repair sealant and air pump you have in the boot.
What you should have in the boot however, is a towing eye and a thin white plastic funnel. Your need the funnel to open the metal flap at the top of the fuel filler if you need to put fuel in from a fuel can.
