you’ll need to add some lubricant.
If the differential is at operating temperature (warm),
add enough lubricant to raise the level to the bottom of
the filler plug hole.
If the differential is cold, add enough lubricant to raise
the level to
1/2 inch (12 mm) below the filler plug hole.
What to Use
Refer to the Maintenance Schedule to determine what
kind
of lubricant to use. See “Recommended Fluids and
Lubricants” in the Index.

When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise.
A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How To Check Power Steering Fluid
When the engine compartment is cool, unscrew the cap
and wipe the dipstick with a clean rag. Replace the cap
and completely tighten it. Then remove the cap again
and look at the fluid level
on the dipstick.
The level should
be at the FULL COLD mark. If
necessary, add only enough fluid to bring the level up to
the mark.
What to Use
Refer to the Maintenance Schedule to determine what
kind of fluid to use. See “Recommended Fluids and
Lubricants” in the Index. Always use the proper fluid.
Failure to use the proper fluid can cause leaks and
damage hoses and seals.

Brake Fluid
Your brake master cylinder
reservoir
is here. It is filled
with
DOT-3 brake fluid.
There are only two reasons why the brake fluid level in the
reservoir might go down. The first is that the brake fluid
goes down to an acceptable level during normal brake
lining wear. When new linings are put in, the fluid level
goes back up. The other reason is that fluid is leaking out
of the brake system. If
it is, you should have your brake
system fixed, since a leak means that sooner or later your
brakes won’t work well, or won’t work at all.
So, it isn’t a good idea to “top off’ your brake fluid.
Adding brake fluid won’t correct a leak. If you add fluid
when your linings are worn, then you’ll have
too much
fluid when you get new brake linings. You should add
(or remove) brake fluid, as necessary, only when work is
done on the brake hydraulic system.
-
-
If you have too much brake fluid, it can spill
on the engine. The fluid
will burn if the engine
is hot enough. You or others could be burned,
and your vehicle could be damaged. Add brake
fluid only when work is done
on the brake
hydraulic system.
Refer to the Maintenance Schedule to determine when to
check your brake fluid. See “Periodic Maintenance
Inspections” in the Index.

Downloaded from www.Manualslib.com manuals search engine When to Check
Check your tires once a month or more. Also, check the
tire pressure of the spare tire.
How to Check
Use a good quality pocket-type gage to check tire
pressure.
You can’t tell.if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
(10
000 to 13 000 km) for any signs of unusual wear.
If unusual wear is present, rotate your tires as soon as
possible and check wheel alignment. Also check for
damaged tires or wheels. See “When It’s Time for New
Tires” and “Wheel Replacement” later in this section for
more information.
I FRT FRT
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation
is the most important. See “Scheduled
Maintenance Services” in the Index for scheduled
rotation intervals.
When rotating your tires, always use one
of the correct
rotation patterns shown here.

Introduction
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 procedures
are 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 your vehicle. To help protect our
environment, and
to keep your vehicle in good
condition, please maintain your vehicle properly.

Services
Using Your Maintenance Schedule
We at General Motors want to help you keep your vehicle
in good working condition. But we don’t know exactly
how you’ll 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 en-ands or in many other ways.
Because
of all the different ways people use their GM
vehicles, maintenance needs vary.
You may even need
more frequent checks and replacements than you’ll find
in the schedules
in this section. So please read this
section and note how you drive.
If you have any
questions on how to keep your vehicle in good
condition, see your GM dealer.
This part tells you the maintenance services you should
have done and when
you should schedule them. If you
go to your dealer for your service needs, you’ll know
that GM-trained and supported service people will
perform the work using genuine GM parts.
The proper fluids and lubricants to use are listed in Part
D. Make sure whoever services your vehicle uses these. All
parts should be replaced and all necessary repairs
done before you or anyone else drives the vehicle.
These schedules are for vehicles that:
