You should begin by disconnecting the negative battery cable to await 90 seconds of standby time to stop the Air Bags along with seat belt pretensioners from activating. Then, remove the rear seat cushion assembly, rear door scuff plate RH, rear side seat back frame RH, rear door opening trim Weather Strip RH, rear seat back assembly RH, tonneau cover assembly, rear floor boards (No. 1, No. 2, and No. 4), deck floor box LH, rear deck floor box, rear deck trim cover, deck trim side panel assembly RH, roof side garnish inner RH, and finally the rear seat outer belt assembly RH by removing the two bolts and the outer belt, followed by the two bolts and the belt outer anchor bracket RH. The rear seat outer belt assembly center requires the removal of its floor anchor bolt after which four claws must be disengaged from the cover before removing both the rear seat headrest RH and center headrest and rear seat back cover RH as well as the retractor side bolt and belt. Begin by installing the center belt of the rear seat outer assembly with its bolt positioned at the retractor side and torque the bolt to 42 N.m (428 kgf.cm, 31 ft.lbf) then proceed to add the rear seatback cover RH followed by the rear seat headrest RH and rear seat center headrest before attaching the four claws to install the cover and finally connect the floor anchor with the bolt at the same torque value. Begin by mounting the rear seat outer belt assembly RH through the retractor side bolt at 42 N.m (428 kgf.cm, 31 ft.lbf) torque followed by anchoring it on the floor at the same strength while checking for quick belt locking. Proceed with the installation of roof side garnish inner RH along with deck trim side panel assembly RH and rear deck trim cover followed by rear deck floor box before installing deck floor box LH and three necessary rear floor boards (No. 4, No. 1, and No. 2). Afterwards, continue with tonneau cover assembly and then move on to install rear seat back assembly RH together with rear door opening trim Weather Strip RH followed by rear side seat back frame RH before completing with rear door scuff plate RH and rear seat cushion assembly. After completing the cable connections to the negative terminal you must initialize the system since some systems need initialization after disconnecting and reattaching the cable.
