Because this service and repair manual is tied to the 2018 GS 450h specifically — the 3.5L V6 (2GR-FXE) hybrid driveline, in Base or F Sport form — every clearance, torque value and diagnostic routine in it is what Lexus published for that build, not a figure carried over from a neighboring model year or a different GS driveline.
