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. The system will show
you when to change the oil
-- usually between 3,000
miles (5 000 km) and 7,500 miles (12 500 km) since
your last oil change. Under severe conditions, the
indicator may come on before 3,000 miles (5 000 km).
Never drive your vehicle more than 7,500 miles
(12 500 km) or 12 months without an oil and
filter change.The system won't detect dust in the oil. So if you drive
in a dusty area, be sure to change your oil and filter
every 3,000 miles (5 000 km) or sooner if the CHANGE
OIL SOON light appears. Remember to reset the Oil
Life System when the oil and filter have been changed.
See ªOil Life Systemº in the Index for information
on resetting.
