Change Oil Display

How do u reset the "change oil display" ? I have a 91 olds tornado trofeo and need to reset the display. Any help would be greatly appreciated.

Should tell you in the owners manual. Is there a reset switch in the fuse box?

some times turn key on pump gas 5 times with engine off,then shut off key

Hold the "Engine data" button and the "Reset" button together till it resets to 100%.
