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
Notice:Maintenance intervals, checks,
inspections, replacement parts, 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 might 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. All recommended
maintenance is important. Improper vehicle
maintenance can even affect the quality of the air
we breathe. Improper uid levels or the wrong
tire ination 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.
394

Using the Maintenance Schedule
We at General Motors want to help you keep your
vehicle in good working condition. But we do not
know exactly how you will drive it. You may drive
very 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 all the different ways people use their
vehicles, maintenance needs vary. You may need
more frequent checks and replacements. So please
read the following and note how you drive. If you
have any questions on how to keep your vehicle in
good condition, see your GM Goodwrench
®dealer.
This schedule is for vehicles that:
carry passengers and cargo within
recommended limits. You will nd these limits
on the Tire and Loading Information label. See
Loading Your Vehicle on page 259.
are driven on reasonable road surfaces within
legal driving limits.
use the recommended fuel. SeeGasoline
Octane on page 283.The services inScheduled Maintenance on
page 396should be performed when indicated.
SeeAdditional Required Services on page 398and
Maintenance Footnotes on page 400for further
information.
{CAUTION:
Performing maintenance work on a vehicle
can be dangerous. In trying to do some
jobs, you can be seriously injured. Do your
own maintenance work only if you have the
required know-how and the proper tools
and equipment for the job. If you have any
doubt, see your GM Goodwrench
®dealer to
have a qualied technician do the work.
Some maintenance services can be complex. So,
unless you are technically qualied and have
the necessary equipment, you should have your
GM Goodwrench
®dealer do these jobs.
395

When you go to your GM Goodwrench®dealer for
your service needs, you will know that GM-trained
and supported service technicians will perform
the work using genuine GM parts.
If you want to purchase service information, see
Service Publications Ordering Information on
page 430.
Owner Checks and Services on page 402tells you
what should be checked, when to check it, and
what you can easily do to help keep your vehicle in
good condition.
The proper replacement parts, uids, and
lubricants to use are listed inRecommended
Fluids and Lubricants on page 406andNormal
Maintenance Replacement Parts on page 408.
When your vehicle is serviced, make sure these
are used. All parts should be replaced and all
necessary repairs done before you or anyone else
drives the vehicle. We recommend the use of
genuine GM parts.Scheduled Maintenance
When the CHANGE OIL SOON message in the
Driver Information Center (DIC) comes on, it means
that service is required for your vehicle. SeeDIC
Warnings and Messages on page 184. Have your
vehicle serviced as soon as possible within the next
600 miles (1 000 km). It is possible that, if you are
driving under the best conditions, the engine oil life
system may not indicate that vehicle service 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. Your dealer/
retailer has trained service technicians who will
perform this work using genuine parts and reset the
system.
If the engine oil life system is ever reset
accidentally, you must service your vehicle within
3,000 miles (5 000 km) since your last service.
Remember to reset the oil life system whenever
the oil is changed. SeeEngine Oil Life System on
page 298for information on the Engine Oil Life
System and resetting the system.
396

When the CHANGE OIL SOON message appears,
certain services, checks, and inspections are
required. Required services are described in the
following for “MaintenanceI” and “MaintenanceII.”
Generally, it is recommended that your rst
service be MaintenanceI, your second service be
MaintenanceII, and that you alternate
MaintenanceIand MaintenanceIIthereafter.
However, in some cases, MaintenanceIImay be
required more often.MaintenanceI— Use MaintenanceIif the
CHANGE OIL SOON message comes on within
10 months since the vehicle was purchased
or MaintenanceIIwas performed.
MaintenanceII— Use MaintenanceIIif the
previous service performed was MaintenanceI.
Always use MaintenanceIIwhenever the CHANGE
OIL SOON message comes on 10 months or more
since the last service or if the message has not
come on at all for one year.

Maintenance Footnotes
(a)Visually inspect brake lines and hoses for
proper hook-up, binding, leaks, cracks, chang, etc.
Inspect disc brake pads for wear and rotors for
surface condition. Inspect drum brake linings/shoes
for wear or cracks. Inspect other brake parts,
including drums, wheel cylinders, calipers,
parking brake, etc.
(b)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing
parts or signs of wear. Inspect power steering
cables for proper hook-up, binding, cracks,
chang, etc.
(c)Visually inspect hoses and have them replaced
if they are cracked, swollen, or deteriorated.
Inspect all pipes, ttings and clamps; replace
with genuine parts as needed. To help ensure
proper operation, a pressure test of the cooling
system and pressure cap and cleaning the outside
of the radiator and air conditioning condenser is
recommended at least once a year.(d)Inspect wiper blades for wear, cracking,
or contamination. Clean the windshield and wiper
blades, if contaminated. Replace wiper blades
that are worn or damaged. See Windshield Wiper
Blade Replacement on page 337andWindshield
and Wiper Blades on page 378for more
information.
(e)Make sure the safety belt reminder light and all
your belts, buckles, latch plates, retractors, and
anchorages are working properly. Look for
any other loose or damaged safety belt system
parts. If you see anything that might keep a safety
belt system from doing its job, have it repaired.
Have any torn or frayed safety belts replaced.
Also look for any opened or broken airbag
coverings, and have them repaired or replaced.
The airbag system does not need regular
maintenance.
(f)Lubricate all key lock cylinders, door hinges
and latches, hood hinges and latches, and trunk lid
hinges and latches. More frequent lubrication
may be required when exposed to a corrosive
environment. Applying silicone grease on
weatherstrips with a clean cloth will make them
last longer, seal better, and not stick or squeak.
