4. Press the SET/CLR button until 100% is displayed.

Or:
1. Turn the ignition to ON/RUN with the engine off.
2. Fully press and release the accelerator pedal three times within five seconds.
The system is reset when the CHANGE ENGINE OIL SOON message goes off.
If the CHANGE ENGINE OIL SOON message comes back on when the vehicle is started, the engine oil life system has not been reset. Repeat the procedure.
