Reinstalling the Cargo Cover Panels
You only need to reinstall as many cargo panels as
you wish.
1. Remove the cargo panel(s) from the storage bag.
You can either leave the bag attached to the side
of the cargo area while it is not in use, or you
can store it outside of the vehicle.

2. Starting with cargo panel 1, place the latches in the
open (unlocked) position. Place cargo panel 1 on
the cargo area rails while holding the back of
the cargo panel up.
Push the panel forward until it is snug against the
Midgate and then let the back of the panel
down being sure that the alignment pegs align with
the receivers (see arrow).
