CHEVROLET COLORADO 2004 1.G Owners Manual

Service Parts Identication Label
You will nd this label on the inside of the glove box. It
is very helpful if you ever need to order parts. On
this label, you will nd the following:
VIN
Model designation
Paint information
Production options and special equipment
Be sure that this label is not removed from the vehicle.
Electrical System
Add-On Electrical Equipment
Notice:Don’t add anything electrical to your vehicle
unless you check with your dealer rst. Some
electrical equipment can damage your vehicle and
the damage wouldn’t be covered by your warranty.
Some add-on electrical equipment can keep other
components from working as they should.
Your vehicle has an air bag system. Before attempting
to add anything electrical to your vehicle, see
Servicing Your Air Bag-Equipped Vehicle on page 1-74.
Windshield Wiper Fuses
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow or ice, the wiper will stop until the motor cools.
If the overload is caused by some electrical problem, be
sure to get it xed.
Power Windows and Other
Power Options
Circuit breakers protect the power windows and other
power accessories. When the current load is too heavy,
the circuit breaker opens and closes, protecting the
circuit until the problem is xed or goes away.
Power and Heated Seat
Circuit Breakers
There is a circuit breaker located underneath the
driver’s side front seat that controls the power and
heated seat functions.
5-103

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of res
caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.
If you ever have a problem on the road and do not have
a spare fuse, you can borrow one that has the same
amperage. Just pick some feature of your vehicle
that you can get along without — like the radio or
cigarette lighter — and use its fuse, if it is the correct
amperage. Replace it as soon as you can.
Engine Compartment Fuse Block
The engine compartment fuse block is located on the
driver’s side of the engine compartment. SeeEngine
Compartment Overview on page 5-12for more
information on location of the engine compartment
fuse block.
To remove the cover, push in on the tab on the end of
the cover and lift. To reinstall the cover, line up the
tab and push down on the cover until the tab clicks
into place.

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
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.
6-2

Using Your 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.
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 4-50.
are driven on reasonable road surfaces within legal
driving limits.
are driven off-road in the recommended manner.
SeeOff-Road Driving with Your Four-Wheel-Drive
Vehicle on page 4-14.
use the recommended fuel. SeeGasoline Octane
on page 5-5.The services inScheduled Maintenance on page 6-4
should be performed when indicated. SeeAdditional
Required Services on page 6-6andMaintenance
Footnotes 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 GM Goodwrench dealer to have a
qualied technician do the work.
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.
6-3

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 get service information, seeService
Publications Ordering Information on page 7-12.
Owner Checks and Services on page 6-8tells 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 6-12andNormal Maintenance Replacement
Parts on page 6-14. 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 OIL light 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.
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. See
Engine Oil on page 5-13for information on the Engine
Oil Life System and resetting the system.
When the CHANGE OIL 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
rst service be MaintenanceI, your second service be
MaintenanceIIand that you alternate MaintenanceIand
MaintenanceIIthereafter. However, in some cases,
MaintenanceIImay be required more often.
MaintenanceI— Use MaintenanceIif the CHANGE
OIL light comes on within ten months since vehicle was
purchased or MaintenanceIIwas performed.
MaintenanceII— Use MaintenanceIIif the previous
service performed was MaintenanceI. Always use
MaintenanceIIwhenever the light comes on ten months
or more since the last service or if the light has not
come on at all for one year.
