Owner Checks and Services on page 6-11tells 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, fluids, and lubricants to
use are listed inRecommended Fluids and Lubricants
on page 6-15andNormal Maintenance Replacement
Parts on page 6-18. 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 ENGINE OIL message (pickup
models) or the change engine oil light (van models)
comes on, it means that service is required for your
vehicle. 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
filter must be changed at least once a year and at this
time the system must be reset. Your GM Goodwrench
®
dealer has GM-trained service technicians who will
perform this work using genuine GM 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 5-24for information on the Engine Oil
Life System and resetting the system.
When the message or light 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
first service be MaintenanceI, your second service be
MaintenanceII, and that you alternate MaintenanceI
and MaintenanceIIthereafter. However, in some cases,
MaintenanceIImay be required more often.
MaintenanceI— Use MaintenanceIif the message
or light 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 message or light comes
on 10 months or more since the last service or if the
message or light has not come on at all for one year.

Maintenance 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.
#Lubricate the front suspension, steering linkage,
transmission shift linkage (pickup models), rear driveline
center splines (van models), and parking brake cable
guides. Pickup models only: Control arm ball joints
require lubrication but should not be lubricated unless
their temperature is 10°F (-12°C) or higher, or they could
be damaged. Vehicles used under severe commercial
operating conditions require lubrication on a regular basis
every 3,000 miles (5 000 km).
(a)A uid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired
and the uid level checked. Add uid if needed.
(b)If you drive regularly under dusty conditions, inspect
the lter or change indicator, if equipped, at each engine
oil change.(c)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.
(d)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing parts,
signs of wear or lack of lubrication. Inspect power
steering lines and hoses for proper hook-up, binding,
leaks, cracks, chang, etc. Pickup models: Visually
check constant velocity joints, rubber boots, and axle
seals for leaks.
(e)Visually inspect hoses and have them replaced if they
are cracked, swollen, or deteriorated. Inspect all pipes,
ttings, and clamps; replace with genuine GM 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.
(f)Visually inspect wiper blades for wear or cracking.
Replace wiper blades that appear worn or damaged
or that streak or miss areas of the windshield.

(g)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.
(h)Lubricate all key lock cylinders, body door hinges,
hood latch assembly, secondary latch, pivots, spring
anchor, release pawl, fuel door hinge, locks, latches,
and any folding or moving seat hardware. Pickup
models: Lubricate tailgate hinges, tailgate linkage,
tailgate handle pivot points, and latch bolt. Van models:
Lubricate hood hinges and rear compartment hinges.
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.
(i)Van Models: If the two chassis mounted fuel
lters have not been replaced, or if the vehicle has
been driven 20,000 miles (32 000 km) or more since the
fuel lters were last replaced, replace both fuel lters.(j)Pickup Models: This vehicle has a CHANGE FUEL
FILTER message in the Driver Information Center (DIC)
to tell you when to replace the fuel lter. See Driver
Information Center (DIC) (Pickup Models Only) on
page 3-9 for more information and how to reset the
message after the fuel lter is replaced. If the fuel lter
has not been replaced, or if the vehicle has been driven
15,000 miles (25 000 km) or more since the fuel lter was
last replaced, replace the lter and reset the message.
(k)Inspect shields and underhood insulation for damage
or looseness. Adjust or replace as required. This is a
Noise Emission Control Service. Applicable to vehicles
sold in the United States and recommended for
vehicles sold in Canada.
(l)Check the air intake system installation to assure
that gaskets are properly sealed and that all hose
connections, fasteners, and other components are tight.
Also check to be sure that the air cleaner housing is
properly seated and the cover ts tightly. Tighten
connections and fasteners or replace damaged parts as
necessary. This is a Noise Emission Control Service.
Applicable to vehicles sold in the United States and
recommended for vehicles sold in Canada.
(m)Check system for interference or binding and for
damaged or missing parts. Replace parts as needed.
Replace any components that have high effort or
excessive wear. Do not lubricate accelerator or
cruise control cables.

occurs rst).
(p)Change automatic transmission uid and external
transmission lter if the vehicle is mainly driven
under one or more of these conditions:
-In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.

-When doing frequent trailer towing.
-Uses such as found in taxi, police, or delivery
service.
(q)Check vent hose at transfer case for kinks and
proper installation.
(r)Drain, ush, and rell cooling system. This service
can be complex; you should have your dealer perform
this service. See Engine Coolant on page 5-34 for
what to use. Inspect hoses. Clean radiator, condenser,
van model fuel operated heater (if equipped), pressure
cap, and ller neck. Pressure test the cooling system
and pressure cap. For van models, see Fuel Operated
Heater (FOH) (Van Models Only) on page 2-8.
(s)Visually inspect belt for fraying, excessive cracks,
or obvious damage. Replace belt if necessary.Owner Checks and Services
