vehicle service is necessary for over a year. However,
your engine oil and lter must be changed at least once
a year and at this time the system must be reset. Your

technicians who will perform this work using genuine
GM parts and reset the system.If the engine oil life system is ever reset accidentally, you
must service your vehicle within 3,000 miles (5 000 km)

required more often.
