GM Chevrolet Avalanche - Manual (Page 139)

Push the panel forward until it is snug against the
midgate and then let the back of the panel down
being sure that the pegs align with the receivers.
3. Push both left latches away from you to lock the
latches (remember that there are two latches on
each side for panel 1). You should hear a click when
each latch locks correctly. Lock the remaining
two right latches on panel 1.
For any cargo cover panel you must lock the left
latch in place before you can lock the right latch. If
you do not follow this exactly, the cargo cover
panels may not lock in place correctly.
