I know, I could drag out the book and probably find this out----but if you were using a floor jack------where are the jacking points on the xB????

 

Look behind the side skirts and see the frame rail that runs front to back on each side.
Near the front and again near the rear wheel, there are knotches cut out of the frame rail.
That is the spot. The knotches are there to secure the top of the sisor jack that the car comes with.

 

Also in the back, dead center middle, near the rear bumper, you'll see a jack point there too. It'll lift the whole rear of the car at one time. It looks like a sharp piece of metal, almost like it would break, but its the jack point.

 

read the owners manual.. its detailed in there
