WARNING: This page is about a different car, the 2012 Mitsubishi Lancer. However, it is still accessible from the selected car via links, so may be relevant.
After checking the trunk lid release cable for proper routing, loosen the trunk lid striker mounting bolts. Change the position of the trunk lid striker relative to the trunk lid latch assembly so that trunk lid locking and unlocking effort is correct.
