When your brake fluid falls to a low level, your brake
warning light will come on. See Brake System Warning
Light on page
3-28.
What to Add
When you do need brake fluid, use only DOT-3 brake
fluid. Use new brake fluid from a sealed container
only. See Part D: Recommended Fluids and Lubricants
on page
6- 15.
Always clean the brake fluid reservoir cap and the area
around the cap before removing it. This will help
keep
dirt from entering the reservoir.
r
With the wrong kind of fluid in your brake
system, your brakes may not work well, or they
may not even work at all. This could cause a
crash. Always
use the proper brake fluid.
Notice:
Using the wrong fluid can badly damage brake
system parts. For example, just a few drops of mineral-based oil, such as engine oil, in your
brake system can damage brake system
parts
so badly that they’ll have to be replaced.
Don’t let someone put in the wrong kind of fluid.
If you spill brake fluid on your vehicle’s painted
surfaces, the paint finish can be damaged.
Be careful not to spill brake fluid on your
vehicle. If you do, wash
it off immediately.

Protection
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.
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps the
environment.
All recommended maintenance procedures
are important. Improper vehicle maintenance can
even affect the quality of the air we breathe. Improper
fluid levels or the wrong tire inflation can increase
the level of emissions from your vehicle.
To help protect
our environment, and to keep your vehicle in good
condition, please maintain your vehicle properly.
Maintenance Requirements
Maintenance intervals, checks, inspections and
recommended fluids and lubricants as prescribed in
this manual are necessary to keep your vehicle in good
working condition. Any damage caused by failure to
follow recommended maintenance may not be covered
by warranty.

Part A: Scheduled Maintenance
Services
This part contains engine oil scheduled maintenance
which explains the engine oil life system and how
it indicates when to change the engine oil and filter.
Also, listed are scheduled maintenance services which
are to be performed at the mileage intervals specified.
Using Your Maintenance Schedule
We at General Motors want to keep your vehicle in good
working condition. But we don’t know exactly how
you’ll drive it. You may drive short distances only a few
times a week. Or you may drive long distances all
the time in very hot, dusty weather. You may use your
vehicle
in making deliveries. Or you may drive it to
work, to do errands or in many other ways.
Because of the different ways people use their vehicles,
maintenance needs may vary. You may need more
frequent checks and replacements.
So please read the
following and note how you drive.
If you have
questions on how to keep your vehicle in good condition,
see your dealer. This part tells
you the maintenance services you
should have done and when you should schedule them.
When you go to your dealer for your service needs,
you’ll know that GM-trained and supported service
people will perform the work using genuine GM parts.
The proper fluids and lubricants to use are listed in
Part D. Make sure whoever services your vehicle uses
these.
All parts should be replaced and all necessary
repairs done before you or anyone else drives the
vehicle.
This schedule is for vehicles that:
carry passengers and cargo within recommended
limits. You will find these on your vehicle’s
Tire-Loading Information label. See Loading
Your
Vehicle on page 4-35.

on page 5-5.

Scheduled Maintenance
The services shown in this schedule up to 100,000 miles
(1 66
000 km) should be repeated after 100,000 miles
(1 66 000 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.
See Part B: Owner Checks and Services on page
6-9
and Part C: Periodic Maintenance Inspections on
page
6- 13.
Footnotes
t 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.
+A good time to check your brakes is during tire
rotation. See Brake System Inspection on page
6-14,
Engine Oil Scheduled Maintenance
Change engine oil and filter as indicated by the GM
Oil Life SystemTM (or every 12 months, whichever
occurs first). Reset the system.
Your vehicle has a computer system that lets you know
when to change the engine oil and filter. 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 light will come on.
Change your oil as soon as possible within the next two
times you stop for fuel. 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 filter 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.
6-5

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 on
page 5-18 for information on resetting the system.
After the services are performed, record the date,
odometer reading and who performed the service on the
maintenance record pages in Part
E of this schedule.
