(166 000 km) at the same intervals. The services shown

Footnotes

The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to
the completion of the vehicle's useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the
maintenance be recorded.* If your vehicle has a GM Oil Life System, the system
will show you when to change the oil
-- usually between
3,000 miles (5 000 km) and 10,000 miles (16 000 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 10,000 miles
(16 000 km) or 12 months, (whichever occurs first),
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 every 3,000
miles (5 000 km) or sooner if the CHANGE OIL SOON
message appears. Remember to reset the Oil Life System
whenever the oil is changed. For more information, see
ªOil Life Systemº in the Index.
+ A good time to check your brakes is during tire rotation.
See ªBrake System Inspectionº under ªPeriodic
Maintenance Inspectionsº in Part C of this schedule.
@ Whenever the tires are rotated, the Check Tire Pressure
System (if your vehicle is so equipped) must be reset.
