Scheduled Maintenance - GMC 2007 Yukon Denali Owner's Manual

Scheduled Maintenance

When the CHANGE ENGINE OIL SOON message
comes on, it means that service is required for
your vehicle. 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, the engine oil and filter 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. See Engine Oil Life System on
page 435 for information on the Engine Oil Life
System and resetting the system.
When the CHANGE ENGINE OIL SOON message
appears, certain services, checks, and inspections
are required. Required services are described
in the following for "Maintenance I" and
®
"Maintenance II." Generally, it is recommended
that your first service be Maintenance I, your
second service be Maintenance II, and that you
alternate Maintenance I and Maintenance II
thereafter. However, in some cases,
Maintenance II may be required more often.
