The Lexus CT is a compact hybrid hatchback that brought Lexus polish to the premium small-car class with strong fuel economy. Its hybrid drivetrain and supporting electronics keep close track of maintenance, and those records need to be cleared after servicing. The oil service reset is the staple job following an oil change, but you might also perform a maintenance light reset, a TPMS reset once tyre pressures are corrected, or a brake pad wear reset after fitting new pads. The hybrid system carries readiness checks of its own as well. Because the dash controls and menus changed during the CT’s lifespan, every procedure on this page is grouped by generation. Choose the matching CT generation from the list below to get the right instructions.
