Hi, I bought my first truck a few months back. I have 4 buttons on the steering wheel, which judging byall the posts I read, they are for the DIC. I don't see anything happening on the dash when I press any of those buttons. Where should I be looking? The only thing I see is the odometer, when I press the odomoeter button on the dash, it cycles between running hours, business and personal mileage. I can't even reset it to track the mileage on a trip. Am I doing something wrong? Thank you very much in advance.
