change oil light

Is this one of the oil life things? If so, and I got this straight from the owners manual. To reset the Engine Oil Life System, do the following: 1. Turn the ignition key to RUN with the engine off. 2. Fully press and release the accelerator pedal three times within five seconds. If the OIL LIFE RESET message displays for 10 seconds, the system is resetting. 3. Turn the ignition key to LOCK. If the CHANGE ENGINE OIL message comes back on when you start your vehicle, the engine oil life system has not reset. Repeat the procedure. If it still does not reset, see your dealer for service. If you need a copy of the owners manual you can download one free here: http://www.autousermanual.com/view/chevrolet/silverado/2007/
