Chevrolet Sonic Owner's Manual: Engine Oil Change
When a 
%CHANGE message displays
in the DIC, have the engine oil and filter changed within the next 1 000 km/600
mi. If driven under the best conditions, the engine oil life system might not indicate
the need for vehicle service for more than a year. The engine oil and filter must
be changed at least once a year and the oil life system must be reset. Your trained
dealer technician can perform this work. If the engine oil life system is reset
accidentally, service the vehicle within 5 000 km/ 3,000 mi since the last service.
Reset the oil life system when the oil is changed. See Engine Oil Life System.
