Hey does anyone know how to turn off/reset the oil maintenance reminder? I have a 2007 Lexus ES 350 with navigation. I don't know if that makes a difference or not. I already tried pressing the trip meter reset button while the car is off and and then keeping the trip meter button pressed down while setting the engine switch to IG-ON. Nothing happened. So I either did something wrong or maybe I was going about it all wrong? Any thoughts would be greatly appreciated. Thanks.
