Most lubricant checks in this section also apply to
four-wheel-drive vehicles. However,
they have two
additional systems
that need lubrication.

How to Check Lubricant
When to Check Lubricant
Refer to the Maintenance Schedule to determine how
often
to check the lubricant. See “Periodic Maintenance
Inspections’’ in the Index.
If
the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant. Add enough lubricant
to raise the level to the bottom of the filler plug hole.
What to Use
Refer to the Maintenance Schedule to determine what
kind
of lubricant to use. See “Recommended Fluids and

When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant and when
to change it. See
“Scheduled Maintenance Services” in the Index.
How to Check Lubricant
If the level is below the bottom of the filler plug hole,
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.

Downloaded from www.Manualslib.com manuals search engine 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.
I A CAUTION:
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.
Checking Brake Fluid
I
&-
You can check the brake fluid without taking off the cap.
Just look at the windows
on the brake fluid reservoir.
The fluid levels should be above MIN. If they aren’t,
have your brake system checked
to see if there is a leak.
After work is done
on the brake hydraulic system, make
sure the levels are above
MIN and below the top of
each window.

If your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.
When to Check
Check your tires once a month or more. Also. check the
tire pressure
of the spare tire.
If you have a compact spare tire. it should be at 60 psi
(420 kPa).
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 rotated every 6.000 to 8.000 miles
(10 000 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. See "When It's Time for New Tires" and
"Wheel Replacement'' later
in this section for
more information.
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.

Downloaded from www.Manualslib.com manuals search engine How This Section is Organized
The remainder of this section is divided into five parts:
“Part
A: Scheduled Maintenance Services” shows
what
to have done and how often. Some of these
services can be complex,
so unless you are technically
qualified and have the necessary equipment,
you should
let your dealer’s service department or another qualified
service center do these jobs.
A 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, have a qualified
technician do the work.
If you are skilled enough to do some work on your
vehicle, you will probably want to get the service
information
GM publishes. See “Service and Owner
Publications”
in the Index. “Part
B: Owner Checks and Services”
tells you
what should be checked and when. It also explains
what you can easily do
to help keep your vehicle in
good condition.
“Part C: Periodic Maintenance Inspections”
explains important inspections that your
GM dealer’s
service department or another qualified service center
should perform.
“Part
D: Recommended Fluids and Lubricants” lists
some products
GM recommends to help keep your
vehicle properly maintained. These products, or their
equivalents, should be used whether
you do the work
yourself or have
it done.
“Part
E: Maintenance Record” provides a place for
you
to record the maintenance performed on your
vehicle. Whenever any maintenance is performed,
be
sure to write it down in this part. This will help you
determine when your next maintenance should be done.
In addition,
it is a good idea to keep your maintenance
receipts. They may be needed
to qualify your vehicle for
warranty repairs.

vehicles, maintenance needs vary. You may even need
more frequent checks and replacements than
