Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for
wear and cracking. SeeScheduled Maintenance
(Gasoline Engine) on page 617for more
information.
Replacement blades come in different types and
are removed in different ways. For proper type and
length, seeNormal Maintenance Replacement
Parts (Gasoline Engines) on page 632.To replace the windshield wiper blade assembly
do the following:
1. Lift the wiper arm away from the windshield.
2. Push the release lever (B) to disengage the
hook and push the wiper arm (A) out of the
blade (C).
3. Push the new wiper blade securely on the
wiper arm until you hear the release lever
click into place.

How to Check
Use a good quality pocket-type gage to check
tire pressure. You cannot tell if your tires are
properly inated simply by looking at them.
Radial tires may look properly inated even when
they’re underinated. Check the tire’s ination
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 rmly onto the valve to
get a pressure measurement. If the cold tire
ination pressure matches the recommended
pressure on the Tire and Loading Information
label, no further adjustment is necessary. If the
ination pressure is low, add air until you reach the
recommended amount.
If you overll 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
torque and wheel nut tightening information, see
Removing the Spare Tire and Tools on page 566.
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 553. Also seeScheduled Maintenance
(Gasoline Engine) on page 617.
{CAUTION:
If you operate your vehicle with a tire
that is badly underinated, the tire can
overheat. An overheated tire can lose air
suddenly or catch re. You or others
could be injured. Be sure all tires
(including the spare) are properly inated.
SeeInation - Tire Pressure on page 551, for
information on proper tire ination.
552

Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your
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 555
andWheel Replacement on page 560for
more information.
Make sure the spare tire is stored securely. Push,
pull, and then try to rotate or turn the tire. If it
moves, use the wheel wrench/hoist shaft to tighten
the cable. SeeChanging a Flat Tire on page 564.
If your vehicle has dual rear wheels, also see
Dual Tire Operation on page 552.The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The
rst rotation is the most important. SeeScheduled
Maintenance (Gasoline Engine) on page 617.
If your vehicle has single rear wheels and the
tread design for your front tires is the same as your
rear tires, use the rotation pattern shown here
when rotating your tires.

Maintenance Schedule
Introduction
This maintenance section applies to vehicles with
a gasoline engine. If your vehicle has a diesel
engine, see the maintenance schedule section in
the DURAMAX
®Diesel Engine Supplement.
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 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. 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.
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.
615

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.
SeeLoading Your Vehicle on page 409.
are driven on reasonable road surfaces within
legal driving limits.
are driven off-road in the recommended
manner. SeeOff-Road Driving on page 372.
use the recommended fuel. SeeGasoline
Octane on page 470.
The services inScheduled Maintenance (Gasoline
Engine) on page 617should be performed
when indicated. SeeAdditional Required Services
(Gasoline Engine) on page 621andMaintenance
Footnotes (Gasoline Engine) on page 623for
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.
SeeDoing Your Own Service Work on
page 469.
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.
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 657.
Owner Checks and Services on page 625tells 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 629andNormal
Maintenance Replacement Parts (Gasoline
Engines) on page 632. 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
(Gasoline Engine)
This maintenance section applies to vehicles with
a gasoline engine. If your vehicle has a diesel
engine, see the maintenance schedule section in
the DURAMAX
®Diesel Engine Supplement.
When the CHANGE ENGINE OIL message 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 lter 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.
