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 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 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 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, be
sure to maintain your vehicle properly.
How This Section is Organized
This maintenance schedule is divided into
four 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 qualified 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.
360

{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, have a qualied
technician do the work. SeeDoing Your
Own Service Work on page 249.
If you want to purchase service information,
seeService Publications Ordering Information
on page 415.“Part B: Owner Checks and Services”
tells you what should be checked and when.
It also explains what you can easily do to keep
your vehicle in good condition.
“Part C: Recommended Fluids and Lubricants”
lists some recommended products necessary
to help keep your vehicle properly maintained.
These products, or their equivalents, should
be used whether you do the work yourself or
have it done.
“Part D: Maintenance Record”is a place
for you to record and keep track of the
maintenance performed on your vehicle.
Keep your maintenance receipts. They may
be needed to qualify your vehicle for warranty
repairs.
361

Part A: Scheduled Maintenance
Services
In this part are scheduled maintenance services
which are to be performed at the mileage intervals
specified.
Using the Maintenance Schedule
We at General Motors want to help 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 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
dealer.
This part tells you the maintenance services you
should have done and when to schedule them.When you go to your dealer for your service
needs, you will 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 C. 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 limits
on your vehicle’s Certification or Tire
Information label. SeeLoading Your Vehicle
on page 238.
•are driven on reasonable road surfaces within
legal driving limits.
•use the recommended fuel. SeeGasoline
Octane on page 251for gasoline engine
vehicles orWhat Fuel to Use on page 253
for diesel engine vehicles.

Scheduled Maintenance
Supplements
If your vehicle has a Caterpillar®diesel engine,
your owner’s manual is supplemented by the
Caterpillar
®Diesel Engine Operation &
Maintenance Manual. If your vehicle has an
Allison Transmission
®, your owner’s manual is
supplemented by an Allison Transmission®
Operator’s Manual. Always refer to these manuals
for related maintenance services.
Scheduled Maintenance
The services shown in this schedule up to
100,000 miles (166 000 km) should be repeated
after 100,000 miles (166 000 km) at the same
intervals for the life of this vehicle. The services
shown after 100,000 miles (166 000 km) should
be repeated at the same miles (km) after
those intervals for the life of this vehicle.Gasoline engine vehicles and some DURAMAX
®
diesel and Isuzu 6H diesel engine vehicles have a
computer that lets you know when to change the
engine oil. This is not based on mileage, but on
engine operation and engine temperature. When
the computer has calculated that the oil needs
changing, the Engine Oil Life System will indicate
that a change is necessary. SeeEngine Oil Life
System (Gasoline Engine) on page 276orEngine
Oil Life System (DURAMAX
®Diesel) on page 278
orEngine Oil Life System (Caterpillar®Diesel
Engine) on page 279.
The “Footnotes” at the end of this Maintenance
Schedule further explain maintenance services.

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.
(1)= If your vehicle has an Allison Transmission
®,
your GM owner manual is supplemented by an
Allison Transmission
®Operator’s Manual. Always
refer to these manuals for related maintenance
services.
383

(28)= Inspect Electronic Vacuum Regulator
Valve (EVRV) filter for excessive contamination
or plugging. If needed, clean filter with solution
of soap and water, let dry and install.
(29)= Drain, flush, and refill cooling system.
This service can be complex; you should
have your dealer perform this service. See
Part C: Recommended Fluids and Lubricants
on page 397for what to use. Inspect hoses.
Clean radiator, condenser, pressure cap, and
neck. Pressure test cooling system and pressure
cap. For Caterpillar
®diesel engines, always
refer to the Caterpillar®Diesel Engine Operation &
Maintenance Manual for coolant recommendations
and change intervals.
(30)= Change the lubricant. See
Part C: Recommended Fluids and
Lubricants on page 397.
(31)= Front axle service: Re-pack upper
kingpin roller bearing.(32)= Air brake service:
•Inspect brake lines and hoses for proper
hook-up, binding, leaks, cracks, chafing,
etc. Inspect drum brake linings for wear or
cracks. Inspect other brake parts at each
wheel, including drums and wheel speed
sensor wiring. Check brake pedal for
excessive free play or travel (or every
6 months, whichever occurs first) and have
serviced if needed. Check brakes more often
if driving habits and conditions result in
frequent braking. Replace air dryer cartridge
only if excessive oil or moisture is present.
A small amount of oil in the system is normal
and should not be considered as a reason
to replace the cartridge.
•Test air lines for leaks; tighten as needed.
Replace compressor filter.
•Inspect air parking brake chamber for leaks
and damage. Inspect lines and hoses for
leaks, cracks, chafing, etc. Also check
all attachments for tightness, wear, or damage.
Note: The spring brake section of the rear
brake diaphragms are non-serviceable.
