Maintenance Schedule
Introduction
Important: Keep engine oil at the proper level
and change as recommended.
Have you purchased the GM Protection Plan? The
Plan supplements your new vehicle warranties.
See your Warranty and Owner Assistance booklet
or your dealer for details.
Maintenance Requirements
Maintenance intervals, checks, inspections and
recommended uids and lubricants as prescribed
in this manual are necessary to keep your
vehicle in good working condition. Any damage
caused by failure to follow scheduled maintenance
may not be covered by warranty.
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep
your vehicle in good working condition, but also
helps the environment. Improper vehicle
maintenance can even affect the quality of the air
we breathe. Improper uid levels or the wrong
tire in ation can increase the level of emissions
from your vehicle. To help protect our environment,
and to keep your vehicle in good condition, be
sure to maintain your vehicle properly.
How This Section is Organized
This maintenance schedule is divided into
ve parts:
“Part A: Scheduled Maintenance Services”
explains what to have done and how often. Some
of these services can be complex, so unless
you are technically quali ed and have the
necessary equipment, you should let your
GM dealer’s service department do these jobs.
Your GM dealer has GM-trained and supported
service people that will perform the work using
genuine GM parts.

Scheduled Maintenance
The services shown in this schedule up to
100,000 miles (160 000 km) should be repeated
after 100,000 miles (160 000 km) at the same
intervals for the life of this vehicle. The services
shown at 150,000 miles (240 000 km) should
be repeated at the same interval after
150,000 miles (240 000 km) for the life of
this vehicle.
SeePart B: Owner Checks and Services on
page 346andPart C: Periodic Maintenance
Inspections on page 351.
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 Driver Information Center
(DIC), it also has the GM Oil Life System, a
computer system that lets you know when to
change the oil and lter. This is based on engine
revolutions and engine temperature and not
on mileage. Based on driving conditions, the
mileage at which an oil change will be indicated
can vary considerably. For the oil life system
to work properly, you must reset the system every
time the oil is changed.
When the system has calculated that oil life has
been diminished, it will indicate that an oil change
is necessary. A CHANGE OIL SOON message
on the Driver Information Center (DIC) will
come on. See DIC Warnings and Messages on
page 148. Change your oil as soon as possible
within the next two times you stop for fuel.
See Engine Oil on page 247. It is possible that,
if you are driving under the best conditions, the
oil life system may not indicate that an oil change
is necessary for over a year. However, your
engine oil and lter must be changed at least
once a year and at this time the system must be
reset. It is also important to check your oil regularly
and keep it at the proper level.

If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5 000 km)
since your last oil change. Remember to reset the
oil life system whenever the oil is changed. See
Engine Oil Life System on page 252 for information
on resetting the system.
+A good time to check your brakes is during
tire rotation. See Brake System Inspection
on page 352.
