Dodge 2014 Journey - Owner Manual - Manual (Page 290)

The cover, when extended, covers the cargo area to keep
items out of sight. Notches in the trim panels near the
liftgate opening secure the extended cover in place.
The cover rolls away neatly inside its housing when not
in use. You can also remove the cover from the vehicle to
make more room in the cargo area.
To install the cover, position it in the vehicle so that the
flat side of the housing faces upward. Then, insert either
the left or the right spring-loaded post (located on the
ends of the cover housing) into the left attachment point
or the right attachment point (shown).
Insert the spring-loaded post on the opposite end of the
cover housing into the attachment point on the opposite
side of the vehicle.
