How to Reset the Oil Life on a Cadillac SRX

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

• Reset only after an oil change; it cannot be reset accurately until the next oil change.
• Alternative: with ignition on and engine off, fully press and release the accelerator pedal three times within five seconds.
• If CHANGE ENGINE OIL SOON returns at startup, the system was not reset; repeat the procedure.
