|Once all of the cover screws are removed, the HV switch turned off, and the final black screw in the HV disconnect switch area is removed, the aluminum cover can be removed.|
Don't forget the small aluminum cover on the passenger rear hatch area.
This cover has a variety of different bolts and screws the plastic screws on the front look like standard Philips, but may not unscrew, and will need to be pried out. There are two bolts on the back, one is hidden by the carpeting. Finally the plastic push plugs will need to be pried out. Once this panel is out, the big cover should easily lift out.
Final step is to remove the negative wire from the 12V battery(caution when this is disconnected, the rear hatch can only be opened with a key)
