I have a 2001 cadillac deville and I am trying to get into the computer --ONBOARD--.

It has to do with the buttons on the dash but I can't figure out which ones.

Thanks

Im not sure what the interior looks like so I can't say for sure... But if you look in the owners manual it should tell you all about it... If you don't have one or you can't find it... You can look up a diagram online... Id try to Google it or go straight to a Cadillac site/forum...
