2. Lower the trunk upper trim panel to detach the clips, then remove the panel from the trunk compartment.



3. Visually inspect the rear shelf subwoofer attachment area for cracks.



^ If the rear shelf subwoofer attachment nut area has cracks, go to REPAIR PROCEDURE.

16. Using a felt tip pen, mark an outline of the area to be cut out on the rear parcel shelf.



NOTE:



Do not mark a larger section than the size of the template.



17. Inspect the rear shelf for cracking that may extend past the cut line. If any crack extends beyond the cut line, drill an 1/8" hole into the end of
