The first step involves removing the rear No.1 seat belt assembly outer RH by dissolving its bolt while subsequent steps require removing the rear seat belt assembly outer center with a nut and then taking out the rear seat belt assembly inner using a bolt. Secure the rear seat belt assembly inner to its place using a bolt which needs to be tightened to 42.0 N.m (420 kgf.cm, 31 ft.lbf). The ELR lock function of the rear seat belt assembly outer center should be tested by observing quick pull-outs of the belt. Install the rear No.1 seat belt assembly outer RH by checking ELR locking while keeping the tilting angle under 45 degrees, then fasten the floor anchor with its bolt using 42.0 N.m (420 kgf.cm, 31 ft.lbf) torque and ensure the anchor part does not touch any protrusion on the floor panel. Afterward, fasten the rear No.1 seat belt assembly outer using a bolt with a torque of 42.0 N.m (420 kgf.cm, 31 ft.lbf).
