How to Reset the Oil Life on a Chevrolet T Series

1. Turn the ignition key to ON/RUN with the engine off.
2. Slowly press the accelerator pedal fully to the floor and release it three times within five seconds.
3. Check that the change engine oil light goes off, which shows the system is resetting.
4. Turn the key to LOCK/OFF.

• Reset the system every time the oil is changed, even if the change engine oil light never came on.
• If the change engine oil light comes back on when the vehicle is started, the system did not reset, so repeat the procedure.
