You will have a carpeted shelf behind the seats.
The carpet has two popper stubs to the rear and on each side of the shelf.
Un popper these studs and lift the carpet up and forward.
You will see a plywood shelf with a hand cut ring on the front edge, this is to secure the shelf.
Move the ring round until it is clear of the shelf. Lift the shelf out and voila there should be the tool tray, complete with jack and wheel removing spanner.
I checked and my car does not have a cut-out or a ring on my shelf.
After removing the carpet the wooden shelf is secured by 10 screws to the wood box.
My car came with a small bag containing a sledge hammer, ring spanner for wheel nut and tire seal spray can. There's actually no space to put that bag.
Is this because i don't have a spare wheel, or due to model or year of manufacture?
