The third generation of the Lexus GS sedan becomes an independent model, without being tied to the analogue of the Toyota Aristo, as was the case with the two predecessors, while the reorganization within the company made the premium Lexus brand completely independent in terms of design and sales. The new Lexus GS now showcases the exclusive L-finesse design (flowing, downward yet temperamental and powerful proportions and lines) that have subsequently defined the appearance of Lexus models. The sedan also features an aerodynamically perfect fastback profile. The styling of the front end with four headlights and the characteristic curve of the tailgate recall the previous model. The car received the in-house code S190.
The power circuits of the Japanese premium car are protected by relays and fuses. The elements are installed in blocks located in the engine compartment, in the passenger compartment and in the trunk. The diagrams considered Lexus GS 300 (S190) 3rd generation 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012 model year with left and right hand drive, also suitable for GS430 and GS460 models
