How to Reset the Oil Life on a Cadillac Escalade EXT

1. Use the vehicle information button to bring up OIL LIFE REMAINING on the DIC.
2. Press and hold the SET/RESET button on the DIC for more than five seconds.
3. Check that the oil life reading changes to 100%.

• Reset the system every time the oil is changed; it will not reset itself.
• If the CHANGE ENGINE OIL SOON message returns at startup, the reset did not work, so repeat the procedure.
• If reset by accident, change the oil at 5 000 km (3,000 mi) since the last change.
