Chevrolet Sonic: Engine Oil Life System

Chevrolet Sonic Owners Manual

The engine oil life system calculates engine oil life based on vehicle use and displays the %CHANGE message on the
DIC when it is necessary to change the engine oil and filter.

Remember, the oil life display must be reset after each oil change. It will not reset itself.

Resetting the Oil Life System

1. Press the MENU button to show Remaining Oil Life on the display. This display shows an estimate of the oil’s remaining useful life. If 99% is displayed, that means that 99% of the current oil life remains.

2. To reset the engine oil life system, press the SET/CLR button while the oil life display is active. After a few seconds, there will be a single chime and the oil life will be reset to 100%.

Be careful not to reset the oil life display accidentally at any time other than when the oil has just been changed. It cannot be reset accurately until the next oil change.
