Answer
Do you mean the light with the wrench on it and the mileage counting backwards? turn key to the #2 position and hit the "o" button or it may say "r" twice. that will put you in the wrench mark. turn key back one notch and hold the button down and keep holding while you turn the key back to the second position. keep holding and dont let go. it will then reset. hope this is the answer you were looking for. e-mail me back if you need help.
