* Trip Odometer: This is easily reset. There's usually a small button on the instrument cluster, often near the speedometer. Press and hold it to reset the trip odometer to zero. Look for a button labeled "TRIP" or a similar designation.
* Maintenance/Oil Life Indicators: These are not actual gauge *readings* but rather warning lights and indicators. The method to reset these varies depending on the specific Silverado model and whether it has a digital or analog display. Consult your owner's manual for the precise instructions. Generally, it involves a sequence of pressing and holding buttons in the instrument cluster or using the OnStar system (if equipped). Some may require a scan tool to be reset properly.
* Check Engine Light: This light indicates a problem detected by the onboard diagnostic system (OBDII). You *cannot* reset this light simply by pressing buttons. The light must be reset *after* the underlying problem that triggered it is fixed. A mechanic can usually do this using an OBDII scanner, after addressing the problem. Sometimes, disconnecting the battery for a short period may reset it, but this is not reliable and might not erase the diagnostic trouble code (DTC).
In short: Identify what specifically you want to "reset." The trip odometer is easily reset; maintenance indicators and the check engine light require different approaches. Your owner's manual is the best resource for the precise procedures.
