2007 CHEVROLET TRAIL BLAZER maintenance schedule

How to Add Automatic
Transmission Fluid
Refer to the Maintenance Schedule to determine
what kind of transmission uid to use. See
Recommended Fluids and Lubricants on page 529.
Add uid only after checking the transmission
uid while it is hot. A cold check is used only as
a reference. If the uid level is low, add only
enough of the proper uid to bring the level up to
the HOT area for a hot check. It does not take
much uid, generally less than one pint (0.5 L).
Do not overll.
Notice:Use of the incorrect automatic
transmission uid may damage your vehicle,
and the damages may not be covered by
your warranty. Always use the automatic
transmission uid listed inRecommended
Fluids and Lubricants on page 529.
After adding uid, recheck the uid level as
described under “How to Check Automatic
Transmission Fluid,” earlier in this section.
When the correct uid level is obtained, push
the dipstick back in all the way; then ip the
handle down to lock the dipstick in place.
Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is
designed to remain in your vehicle for ve years or
150,000 miles (240 000 km), whichever occurs
rst, if you add only DEX-COOL
®extended
life coolant.
The following explains your cooling system and
how to add coolant when it is low. If you have
a problem with engine overheating, seeEngine
Overheating on page 418.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Give freezing protection down to
−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.

Brakes
Brake Fluid
The brake master
cylinder reservoir is
lled with DOT-3 brake
uid. SeeEngine
Compartment Overview
on page 396for the
location of the reservoir.
There are only two reasons why the brake uid
level in the reservoir might go down. The rst
is that the brake uid goes down to an acceptable
level during normal brake lining wear. When new
linings are put in, the uid level goes back up.
The other reason is that uid is leaking out of the
brake system. If it is, you should have the
brake system xed, since a leak means that
sooner or later the brakes will not work well.So, it is not a good idea to top off the brake uid.
Adding brake uid will not correct a leak. If you
add uid when the linings are worn, then you will
have too much uid when you get new brake
linings. You should add or remove brake uid,
as necessary, only when work is done on
the brake hydraulic system.
{CAUTION:
If you have too much brake uid, it can
spill on the engine. The uid will burn if
the engine is hot enough. You or others
could be burned, and your vehicle could
be damaged. Add brake uid only when
work is done on the brake hydraulic
system. See “Checking Brake Fluid” in
this section.
Refer to the Maintenance Schedule to determine
when to check your brake uid. SeeScheduled
Maintenance on page 519.

Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for

Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference

authorization to use this equipment.
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 466
andWheel Replacement on page 470for
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 to tighten the
cable. For information on storing or removing the
spare tire, seeChanging a Flat Tire on page 474.
The purpose of regular rotation is to achieve
more uniform wear for all tires on the vehicle.
The rst rotation is the most important.

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

Any damage caused by failure to follow
scheduled maintenance might 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.
