The third-generation Lexus GS (S190) 2005-2012 was a sporting executive saloon offered with the 3.5 V6, a 4.6 V8 and the supercharged-feel GS 450h hybrid. After servicing, the GS keeps its service indicator lit until the cluster is reset. The reset owners reach for most is the oil service reset to clear the maintenance light, plus a service reminder reset after the full interval and a TPMS reset once tyre pressures are set. On the 450h hybrid the 12V battery may also need confirming after replacement. Choose the relevant guide below for your S190 GS.
