How do you get the spare wheel off a citroen berlingo van?

The spare wheel is on the Citroen Berlingo is underneath the rear of the van. Place the jack into the vertical tube on the left rear of wheel retaining bracket. Open the rear doors on the van, and look for two squares of plastic with cut-out slits on each side. Insert a screwdriver into the slits to lift off. Loosen the bolts under the plastic squares, but do not take completely off. Swing the bracket clear, lower the jack, and remove the wheel.
