If it's the lights in the middle row and the boot (third row) then they have individual switches on them that over-rides the automatic function. I would (at night!) start the car then get out and get in the middle row. If the lights are on then press the button so that it's off. Voila! Same for the light in the boot, although do check which variant you've got as some have buttons and some have a sliding plastic cover to switch them on/off. Worth checking that the auto function for the interior lights is selected on in the front as well - it's button A (rear left) on the diagram on page 78 of the PDF owner's manual.
