1. Turn the ignition to the "ON" position (without starting the engine).
2. Access the DIC Menu: Locate the button on your steering wheel that allows you to cycle through the DIC menus. This is usually a button with an information icon or similar. Press this button repeatedly until you reach the "Information" or similar menu in the DIC display.
3. Navigate to the Oil Life Menu: Continue pressing the button to cycle through the various DIC information screens until you see a display related to oil life, oil change, or maintenance. This might be labeled as "Oil Life Remaining," "Engine Oil Life," or something similar. The exact wording varies.
4. Reset the Oil Life: Once you've found the oil life screen, there's usually a way to select it. This could involve pressing the button again, holding it down, or using another button (e.g., a "SET" or "OK" button on the steering wheel or center console). The manual should specify the exact steps.
5. Confirmation: After following the necessary steps, the oil life percentage should reset to 100% (or a similar indicator, like a message stating that an oil change is no longer needed).
If you're having trouble:
* Consult your owner's manual: This is the most reliable source for the precise instructions for your specific vehicle. The steps might be slightly different than described above.
* Look for a "SET" or similar button: Many Cadillac models use a "SET" button in conjunction with the DIC navigation buttons to make selections and confirmations.
* Try different button combinations: Experiment with pressing and holding buttons, or combining button presses with the ignition switch.
Important Note: Resetting the oil life monitor *does not* actually change your oil. It only resets the indicator in the car's computer. You *must* change your oil according to the manufacturer's recommended intervals, regardless of what the indicator says. Failing to do so can severely damage your engine.
