Maintenance Schedule
Introduction
This maintenance section applies to vehicles with a
gasoline engine. For diesel engine vehicles, see the
maintenance schedule section in the DURAMAX Diesel
manual.
Notice:Maintenance intervals, checks, inspections,
recommended fluids, and lubricants are necessary
to keep this vehicle in good working condition.
Damage caused by failure to follow scheduled
maintenance might not be covered by the vehicle
warranty.
Proper vehicle maintenance helps to keep the vehicle
in good working condition, improves fuel economy, and
reduces vehicle emissions for better air quality. Because of all the different ways people use vehicles,
maintenance needs vary. The vehicle might need
more frequent checks and services. Please read the
information under Scheduled Maintenance. To keep the
vehicle in good condition, see your dealer/retailer.
The maintenance schedule is for vehicles that:
.carry passengers and cargo within recommended
limits on the Tire and Loading Information label.
See
Loading the Vehicle on page 5‑30.
.are driven on reasonable road surfaces within legal
driving limits.
.are driven off‐road in the recommended manner.
SeeOff-Road Driving on page 5‑11.
.use the recommended fuel. See Gasoline Octaneon page 6‑7.

{WARNING:
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 dealer/retailer to have a
qualified technician do the work. SeeDoing Your
Own Service Work on page 6‑5.
At your General Motors dealer/retailer, you can be
certain that you will receive the highest level of service
available. Your dealer /retailer has specially trained
service technicians, uses genuine GM replacement
parts, as well as, up to date tools and equipment to
ensure fast and accurate diagnostics.
The proper replacement parts, fluids, and lubricants to
use are listed in Recommended Fluids and Lubricants
on page 7‑12andMaintenance Replacement Partson
page 7‑15. We recommend the use of genuine parts
from your dealer/retailer.
Rotation of New Tires
To maintain ride, handling, and performance of the
vehicle, it is important that the first rotation service for
new tires be performed when they have 8 000 to
13 000 km (5,000 to 8,000 miles). See Tire Inspection
and Rotation on page 6‑80.
Scheduled Maintenance
When the Change Engine Oil Soon
Message Displays
Change engine oil and filter. See Engine Oilon
page 6‑18. An Emission Control Service.
When the Change Engine Oil Soon message displays,
service is required for the vehicle as soon as possible,
within the next 1 000 km/600 miles. If driving under the
best conditions, the engine oil life system might not
indicate the need for vehicle service for more than a
year. The engine oil and filter must be changed at least
once a year and the oil life system must be reset. Your
dealer/retailer has trained service technicians who will
perform this work and reset the system. If the engine oil
life system is reset accidentally, service the vehicle
within 5 000 km/3,000 miles since the last service.
Reset the oil life system whenever the oil is changed.
See Engine Oil Life System on page 6‑20.
7-3

When the Change Engine Oil Soon message
displays, certain services, checks, and inspections are
required. The services described for MaintenanceI
should be performed at every engine oil change.
The services described for Maintenance IIshould be
performed when:
.Maintenance Iwas performed the last time the
engine oil was changed.
.It has been 10 months or more since the Change
Engine Oil Soon message has displayed or since
the last service.
Maintenance I
.Change engine oil and filter. See Engine Oilon
page 6‑18. An Emission Control Service.
.Engine coolant level check. See Engine Coolanton page 6‑31.
.Windshield washer fluid level check. See
Windshield Washer Fluid on page 6‑38.
.Tire inflation check. SeeInflation - Tire Pressureon page 6‑72.
.Tire wear inspection. See Tire Inspection and
Rotation on page 6‑80.
.Rotate tires. See Tire Inspection and Rotationon
page 6‑80.
.Fluids visual leak check (or every 12 months,
whichever occurs first). A leak in any system
must be repaired and the fluid level checked.
.Engine air cleaner filter inspection (vehicles
driven in dusty conditions only). See Engine Air
Cleaner/Filter on page 6‑21.
.Brake system inspection (or every 12 months,
whichever occurs first).
.For vehicles with Allison Transmission®only:
At the first engine oil change only, replace external
transmission filter.
Maintenance II
.Perform all services described in Maintenance I.
.Steering and suspension inspection. Visual
inspection for damaged, loose, or missing parts or
signs of wear.
.Lubricate the front suspension, steering linkage,
and parking brake cable guides. Control arm
ball joints on 2500/3500 series vehicles require
lubrication but should not be lubricated unless their
temperature is−12°C (10°F) or higher, or they
could be damaged. Control arm ball joints on
1500 series vehicles are maintenance‐free.
Vehicles used under severe commercial operating
conditions require lubrication on a regular basis
every 5 000 km/3,000 miles.
7-4

.Engine cooling system inspection. Visual
inspection of hoses, pipes, fittings, and clamps and
replacement, if needed.
.Windshield wiper blade inspection for wear,
cracking, or contamination and windshield and
wiper blade cleaning, if contaminated. See
Windshield and Wiper Blades
on page 6‑114.
Worn or damaged wiper blade replacement.
See Windshield Wiper Blade Replacement
on
page 6‑63.
.Body hinges and latches, key lock cylinders,
folding seat hardware, and tailgate hinges,
linkage, and handle pivot points lubrication.
See Recommended Fluids and Lubricants
on
page 7‑12. More frequent lubrication may be
required when vehicle is exposed to a corrosive
environment. Applying silicone grease on
weatherstrips with a clean cloth makes them last
longer, seal better, and not stick or squeak.
.Restraint system component check. See Checking
the Restraint Systems on page 2‑93.
.Automatic transmission fluid level check and
adding fluid, if needed. See Automatic
Transmission Fluid (4-Speed Transmission)
on
page 6‑23or Automatic Transmission Fluid
(6-Speed Transmission) on page 6‑26.
.Four‐wheel drive vehicles: Transfer case fluid level
check and adding fluid, if needed.
.Engine air cleaner filter inspection. See Engine Air
Cleaner/Filter on page 6‑21.
.Vehicles with diesel engine or GVWR above
4 536 kg (10,000 lbs) only: Shields inspection 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.
Additional Required Services
At the First 160 km/100 Miles, 1 600 km/
1,000 Miles, and 10 000 km/6,000 Miles
.For vehicles with dual wheels: Check dual wheel
nut torque. For proper torque, see Capacities and
Specifications on page 6‑126.

page 6‑18.
.Engine coolant level check. See Engine Coolanton page 6‑31.
.Windshield washer fluid level check. See
Windshield Washer Fluid on page 6‑38.

.Accelerator pedal check for damage, high effort,
or binding. Replace if needed.
First Engine Oil Change After Every
40 000 km/25,000 Miles
.Fuel system inspection for damage or leaks.
.Four‐wheel drive only: Transfer case fluid change
(extreme duty service) for vehicles mainly driven
off‐road in four‐wheel drive. Vehicles used for
farming, mining, forestry, Department of Natural
Resources (DNR), and snow plowing occupations
meet this definition. Check vent hose at transfer
case for kinks and proper installation. Check to be
sure vent hose is unobstructed, clear, and free of
debris. During any maintenance, if a power washer
is used to clean mud and dirt from the underbody,
care should be taken to not directly spray the
transfer case output seals. High pressure water
can overcome the seals and contaminate the
transfer case fluid. Contaminated fluid will
decrease the life of the transfer case and should
be replaced.
