The 2007 Lexus GS 450h features a dual-zone automatic climate control system with basic controls such as auto, off, and defrost, and temperature adjustment on the instrument panel. However, one must tap the Climate button and enter the touch-screen realm to adjust fan speed and mode – this multi-step process could be simplified with simple dials, though would admittedly be much less sophisticated. Buttons for the front climate-controlled seats are hidden below the sliding center armrest, with three settings each for heating and cooling.
