Long Trip/Highway Scheduled Maintenance
7-21
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
at 150,000 miles (240 000 km) should be performed at
the same interval after 150,000 miles (240 000 km).
See ªOwner Checks and Servicesº and ªPeriodic
Maintenance Inspectionsº following.
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 the GM Oil Life System, the
system will show you when to change the engine oil and
filter
-- 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
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
ENGINE 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.
@ Whenever the tires are rotated, the Check Tire Pressure
System (if your vehicle is so equipped) must be reset.
+ 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.
