To install the coupe models, it is advisable to start by lifting the liftgate and take off the trim panel. When the lock is not functioning, tailgate can be opened manually by going inside the vehicle through an emergency cover and then using the lever. Then, remove the wiring of the liftgate lock, lift out the retaining fasteners and the lock of the tailgate, and install it again in the same way that it was removed. Next detach the tailgate wiper motor, dissolve the wiring connections with the handle/release unit and the retaining fasteners that connect the unit to the liftgate and locking brackets and rotate the unit clockwise out of the liftgate. Before reattaching the trim panel, be sure that the lock parts have been properly installed. In wagon models, open the liftgate and take out the trim panel, then unplug the electrical connector on the back side of the lock, remove the fastening screw, and remove the lock, and it is installed the same way. Detach the electrical connector on the rear of the handle button, take out the two retaining fasteners and the threaded pin, and then remove the cover and the handle/release button out of the liftgate, making sure that the operation of the lock parts is checked before restoring the trim panel. Finally, the liftgate support struts to all models are also removed similarly to the hood support struts.
