Turn Ignition On: Place the vehicle ignition in the ON position without starting the engine, or bring up the oil life screen on the cluster.
-
Press and Hold Checkmark: Press and hold the checkmark button on the right steering wheel pad for several seconds.
-
Verify 100% Reset: Watch the display update to confirm the oil life percentage has successfully reset back to 100%.
