The only way I know how to reset mine is to press two buttons on the steering wheel the same time the info butten and the enter button that looks like an arrow. This puts you in a sub menu on the DIC where you can change options such was horn chirp when lock, turn the remote start feature on/off ECT... One option is reset oil life, you have to hold the enter button down for like three seconds on that option before it will reset to 100. Now some one said something another way to do it is pressing the gas pedel three times or something along those lines? If that is correct that could be how I am doing it. When I am in the car with it on acc playing the radio on a smoke break at work I do sometimes mess with the pedal just messin around...is this really also a way to reset it?
