Close-Out Panel Removing the Close-Out Panel
1. Close the panel. If the close-out panel is not closed
and resting on the trim panel, it cannot be removed.
2. Pull the panel toward you to unsnap it. Then slide the
close-out panel along the groove in the trim panel.
Reverse the steps to install the panel.
The close-out panel can be closed for hidden storage in
the rear area of your vehicle.
When carrying large or heavy items, it is a good idea to
open the panel and place the items in the rear area.
