Scheduled Maintenance - GMC C-Series 2001 Owner's Manual

Scheduled Maintenance

The services shown in this schedule up to 100,000 miles
(166 000 km) should be performed after 100,000 miles
(166 000 km) at the same intervals. The services shown
after 100,000 miles (166 000 km) should be performed
at those same intervals.
This vehicle has a computer that lets you know when to
change your engine oil. This is not based on mileage,
but on engine revolutions and engine operating
temperature. When the computer has calculated that the
oil needs changing, the Oil Life Monitor will indicate
that a change is necessary.
The "Footnotes" at the end of this Maintenance
Schedule further explain maintenance services.
