Scheduled Maintenance
When the CHANGE OIL message comes on, it
means that service is required for your vehicle.
SeeDIC Warnings and Messages on page 198.
Have your vehicle serviced as soon as possible
within the next 600 miles (1 000 km). It is possible
that, if you are driving under the best conditions,
the engine oil life system may not indicate
that 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 GM Goodwrench
®
dealer has GM-trained service 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) since your last service.
Remember to reset the oil life system whenever
the oil is changed. SeeEngine Oil Life System
on page 328for information on the Engine Oil Life
System and resetting the system.
When the CHANGE OIL message appears,
certain services, checks, and inspections are
required. Required services are described in the
following for “MaintenanceI” and “MaintenanceII.”
Generally, it is recommended that your rst
service be MaintenanceI, your second service
be MaintenanceII, and that you alternate
MaintenanceIand MaintenanceIIthereafter.
However, in some cases, MaintenanceIImay
be required more often.
