How to Check
Use a good quality pocket-type gage to check
tire pressure. You cannot tell if your tires are
properly inflated simply by looking at them. Radial
tires may look properly inflated even when they are
underinflated. Check the tire’s inflation pressure
when the tires are cold. Cold means your vehicle
has been sitting for at least three hours or driven
no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem.
Press the tire gage firmly onto the valve to get a
pressure measurement. If the cold tire inflation
pressure matches the recommended pressure on
the Tire and Loading Information label, no further
adjustment is necessary. If the pressure is low, add
air until you reach the recommended amount.
If you overfill the tire, release air by pushing on
the metal stem in the center of the tire valve.
Recheck the tire pressure with the tire gage.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Dual Tire Operation
When the vehicle is new, or whenever a wheel, wheel
bolt or wheel nut is replaced, check the wheel nut torque
after 100, 1,000 and 6,000 miles (160, 1 600 and
10 000 km) of driving. For proper wheel nut tightening
information, see “Removing the Flat Tire and Installing
the Spare Tire” later in this section, underChanging a
Flat Tire on page 5-80. Also see “Wheel Nut Torque”
underCapacities and Specifications on page 5-110.
The outer tire on a dual wheel setup generally wears
faster than the inner tire. Your tires will wear more
evenly and last longer if you rotate the tires periodically.
SeeTire Inspection and Rotation on page 5-69.
Also seeScheduled Maintenance on page 6-4.
{CAUTION:
If you operate your vehicle with a tire that is badly
underinflated, the tire can overheat. An overheated
tire can lose air suddenly or catch fire. You or
others could be injured. Be sure all tires (including
the spare) are properly inflated.
SeeTires on page 5-54andInflation - Tire Pressure on
page 5-62for more information on proper tire inflation.
5-63

Tire Inspection and Rotation
Inspect tires regularly for signs of wear or damage.
Also inspect the spare tire. For more information
on tire inspection, seeWhen It Is Time for
New Tires on page 5-71.
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km). SeeScheduled Maintenance
on page 6-4.
The purpose of a regular tire rotation is to
achieve a uniform wear for all tires on the vehicle.
This will ensure that the vehicle continues to
perform most like it did when the tires were new.
Any time you notice unusual wear, rotate the
tires as soon as possible and check wheel
alignment. Also check for damaged tires or wheels.
SeeWhen It Is Time for New Tires on page 5-71
andWheel Replacement on page 5-76.If your vehicle has single rear wheels, always
use the correct rotation pattern shown here when
rotating the vehicle’s tires. Do not include the spare
tire in the tire rotation.

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.
Important: Keep engine oil at the proper level and
change as recommended.
Have you purchased the GM Protection Plan? The Plan
supplements the vehicle warranties. See the Warranty
and Owner Assistance booklet or your dealer/retailer 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 this vehicle in good working condition.
Any damage caused by failure to follow scheduled
maintenance might not be covered by the vehicle
warranty.
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep the
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 fluid levels or
the wrong tire inflation can increase the level of emissions
from the vehicle. To help protect the environment, and to
keep the vehicle in good condition, be sure to maintain
the vehicle properly.
6-2

Using the Maintenance Schedule
We want to help keep this vehicle in good working
condition. But we do not know exactly how you will drive
it. You might drive very short distances only a few times a
week. Or you might drive long distances all the time in
very hot, dusty weather. You might use the vehicle in
making deliveries. Or you might 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 might 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 the vehicle in good
condition, see your dealer/retailer.
This schedule is for vehicles that:
•carry passengers and cargo within recommended
limits on the Tire and Loading Information label.
SeeLoading the Vehicle on page 4-18.
•are driven on reasonable road surfaces within legal
driving limits.
•use the recommended fuel. SeeGasoline Octane
on page 5-6.
The services inScheduled Maintenance on page 6-4
should be performed when indicated. SeeAdditional
Required Services on page 6-6andMaintenance
Footnotes (Gasoline Engine) on page 6-7for 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 dealer/retailer to have a
qualified technician do the work. SeeDoing Your
Own Service Work on page 5-4.
Some maintenance services can be complex. So, unless
you are technically qualified and have the necessary
equipment, have your dealer/retailer do these jobs.
When you go to your dealer/retailer for service, trained
and supported service technicians will perform the work
using genuine parts.
To purchase service information, seeService
Publications Ordering Information on page 7-15.
Owner Checks and Services on page 6-9tells what
should be checked, when to check it, and what
can easily be done to help keep the vehicle in good
condition.
