Engine Oil Scheduled Maintenance
Change engine oil and filter as indicated by the GM Oil Life System™
or every 12 months, whichever occurs first. Reset the system.
Your vehicle has a computer system that lets you know when to change
the engine oil and filter. This is based on engine revolutions and engine
temperature and not on mileage. Based on driving conditions, the mileage at
which an oil change will be indicated can vary considerably. For the oil life
system to work properly, you must reset the system every time the oil is changed.
When the system has calculated that oil life has been diminished, it
will indicate that an oil change is necessary. A CHANGE ENGINE OIL message
in the Driver Information Center (DIC) will come on. Change your oil as soon
as possible within the next two times you stop for fuel. It is possible that,
if you are driving under the best conditions, the oil life system may not
indicate that an oil change is necessary for over a year. However, your engine
oil and filter must be changed at least once a year and at this time the system
must be reset. It is also important to check your oil regularly and keep it
at the proper level.
If the system is ever reset accidentally, you must change you oil at
5,000 km (3,000 mi) since your last oil change. Remember to
reset the oil life system whenever the oil is changed. Refer to
GM Oil Life System Resetting
.
Footnotes
[Dagger] The U.S. Environmental Protection Agency or the California
Air Resources Board has determined that the failure to perform this maintenance
item will not nullify the emission warranty or limit recall liability
prior to the completion of the vehicle's useful life.
We, however, urge that all recommended maintenance services be
performed at the indicated intervals and the maintenance
be recorded.
