How to Reset the Maintenance Light on a 2005 Buick Regal?

[Penelope]

Use the Driver Information Center control buttons on the right side of the steering wheel to display the remaining oil life on the instrument cluster screen. Here are the detailed steps: Method: When the "Oil Life" display is activated, press and hold the "√" (OK/Confirm) button for several seconds to reset the oil life system. After resetting, the display will show "Oil Life 100%". Note: If the "Change Engine Oil" message reappears after starting the vehicle, it indicates the engine oil life was not reset, and you should repeat the above steps. The oil life monitoring system should be reset every time the engine oil is changed so the system can calculate the next oil change interval.
