How to Reset the Oil Life on a Cadillac XT5

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

• Reset the system every time the oil is changed, and only then, because it cannot be reset accurately until the next oil change.
• The manual mentions a second reset method, but the page cuts off before giving its steps.
• If the system is reset accidentally, change the oil at 5 000 km (3,000 mi) since the last change.
