Scheduled Maintenance - GMC C series 2002 Owner's Manual

Scheduled Maintenance

The services shown in this schedule up to 100,000 miles
(166 000 km) should be repeated after 100,000 miles
(166 000 km) at the same intervals for the life of
this vehicle. The services shown after 100,000 miles
(166 000 km) should be repeated at the same miles (km)
after those intervals for the life of this vehicle.
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.
