How to Reset the Engine Oil Life System

WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.

The Engine Oil Life System calculates when to change the engine oil and filter based on vehicle use. Whenever the oil is changed, reset the system so it can calculate when the next oil change is required. If a situation occurs where the oil is changed prior to a CHANGE ENGINE OIL SOON message coming on, reset the system.

Always reset the engine oil life to 100 percent after every oil change. It will not reset itself. To reset the Engine Oil Life System on most vehicles:

Display the OIL LIFE REMAINING on the DIC. If the vehicle does not have DIC buttons, the vehicle must be in P (Park) to access this display.
Press and hold the SET/RESET button on the DIC, or the trip odometer reset stem if the vehicle does not have DIC buttons, for more than five seconds. The oil life will change to 100 percent.

On all vehicles, the Engine Oil Life System can be reset as follows:

Turn the ignition to ON/RUN with the engine off.
Fully press the accelerator pedal slowly three times within five seconds.
Display the OIL LIFE REMAINING on the DIC. If the display shows 100 percent, the system is reset.

If the vehicle has a CHANGE ENGINE OIL SOON message and it comes back on when the vehicle is started and/or the OIL LIFE REMAINING is near 0 percent, the Engine Oil Life System has not reset. Repeat the procedure.
