Manual climate control functions are bundled with the Lexus LS 460L’s navigation system, but that’s OK because they’re rarely used. Commonly referenced automatic functions are separate from the navigation display, arrayed in the center of the dash and clearly visible. Seat heating and cooling are operated using twist knobs on the center console. Our test car had climate-controlled rear seats but not the optional four-zone automatic climate system. Instead, the rear passenger compartment featured adjustable vents.
