2007 CHEVROLET TRAIL BLAZER maintenance

Finish Damage
Any stone chips, fractures or deep scratches in
the nish should be repaired right away. Bare
metal will corrode quickly and may develop into
major repair expense.
Minor chips and scratches can be repaired with
touch-up materials available from your dealer.
Larger areas of nish damage can be corrected
in your dealer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and
dust control can collect on the underbody. If these
are not removed, corrosion and rust can develop
on the underbody parts such as fuel lines, frame,
oor pan, and exhaust system even though
they have corrosion protection.At least every spring, ush these materials from
the underbody with plain water. Clean any
areas where mud and debris can collect.
Dirt packed in close areas of the frame should be
loosened before being ushed. Your dealer or
an underbody car washing system can do this
for you.
Chemical Paint Spotting
Some weather and atmospheric conditions can
create a chemical fallout. Airborne pollutants can
fall upon and attack painted surfaces on the
vehicle. This damage can take two forms: blotchy,
ring-shaped discolorations, and small, irregular
dark spots etched into the paint surface.
Although no defect in the paint job causes this,
we will repair, at no charge to the owner, the
surfaces of new vehicles damaged by this fallout
condition within 12 months or 12,000 miles
(20 000 km) of purchase, whichever occurs rst.

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 might not be covered
by warranty.
516

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.
517

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 356.

manner. SeeOff-Road Driving (Except SS) on
page 323.
use the recommended fuel. SeeGasoline
Octane on page 388.
The services inScheduled Maintenance on
page 519should be performed when indicated.
SeeAdditional Required Services on page 522and
Maintenance Footnotes on page 523for 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

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 554.
Owner Checks and Services on page 525tells 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 529andNormal
Maintenance Replacement Parts on page 532.
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 light or CHANGE
ENGINE OIL DIC message comes on, it means
that service is required for your vehicle. See
Change Engine Oil Light on page 216orDIC
Warnings and Messages on page 224. 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 dealer/retailer has trained service
technicians who will perform this work using
genuine 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 408for information on the Engine Oil Life
System and resetting the system.
519

When the change engine oil light or CHANGE
ENGINE OIL DIC message 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
MaintenanceII, and that you alternate
MaintenanceIand MaintenanceIIthereafter.
However, in some cases, MaintenanceIImay be
required more often.MaintenanceI— Use MaintenanceIif the light
or message 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 light
or message comes on 10 months or more since
the last service or if the light or message has
not come on at all for one year.
