I have a 2015 ES350 and the very annoying warning tone when I open the driver's door AFTER stopping the engine with the headlights still on. They automatically cut off, so why does Lexus insist on the warning tone to tell one the lights are on?? Can not figure out how to change the setting! If I turn the lights to off, there is no tone when opening the door ..... I guess I'll have to go to Lexus dealer and see if they know how to reset ....
