Here's the most common procedure:
1. Turn the ignition key to the "ON" position (but don't start the engine). This powers up the vehicle's systems.
2. Locate the odometer/trip meter reset button. This is usually a small button on the instrument cluster, often near the speedometer. It might be labelled with a small triangle or a similar symbol.
3. Press and hold the button. Different models might require you to press and hold, or press and release several times.
4. Look for a specific sequence. While holding the button (or cycling through presses), you should look for the oil life indicator to reset, or to display something like "OIL LIFE RESET" or a similar message. *This is the crucial step and might require experimentation*. Some models require you to hold the button for a few seconds until the message appears, while others might involve a series of short presses. Some may even require using the trip odometer reset button in conjunction with another button (like the gas gauge reset).
5. If you can't find a specific reset procedure in your owner's manual, it may not be possible to manually reset it. In these cases the system automatically resets after an oil change.
Crucial Note: Your owner's manual is the definitive source of information for your specific 2004 Silverado model and trim level. Consult it for the exact steps. The information above is a general guideline, and the procedure might vary slightly. If you can't find the information in the manual, search online for "[Your Silverado's Specific Trim] oil life reset" to find videos or forum posts specific to your truck.
