How to Reset the Oil Life on a Cadillac XT6

1. Use the DIC controls on the right side of the steering wheel to bring up REMAINING OIL LIFE on the DIC.
2. Press the thumbwheel on the DIC controls and hold it down for a few seconds.
3. This clears the CHANGE ENGINE OIL SOON message and sets the oil life back to 100%.

• Reset only after an oil change; it cannot be reset accurately until the next oil change.
• The manual also describes a second reset method, but its steps continue past these pages.
