What to Use:
Refer to the Maintenance Schedule to
determine what kind of lubricant to use.
See “Recommended Fluids and
Lubricants” in the Index.
Four- Wheel Drive
Most lubricant checks in this section
also apply to four-wheel-drive vehicles.
However, they have two additional
systems that need lubrication.

determine how often to check the
lubricant and when
to change it. See
‘ ‘Scheduled Maintenance Services’ ’ in

How to Check Lubricant: 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.

If your spare wheel does not match your
other wheels, you may want to use this
pattern.
After the tires have been rotated, adjust
the front and rear inflation pressure as
shown
on the Tire-Loading Information
label. Make certain that all wheel nuts
are properly tightened. See “Wheel Nut
Torque’’ in the Index.
CA U TION
A
Rust or dirt on a wheel, or on
the parts
to which it is
fastened, can make the wheel nuts
become loose after a time. The
wheel could come off and cause an
accident. When you change a
wheel, remove any rust or dirt
from places where the wheel
attaches to the vehicle. In an
emergency, you can use
a cloth or
paper towel to
do this; but be sure
to use a scraper or wire brush
later,
if you need to, to get all the
rust or dirt
off. (See “Changing a
Flat Tire” in the Index.)

When It’s Time for New Tires
One way to tell when it’s time for new
tires is to check the treadwear
indicators, which will appear when your
tires have only
2/32 inch (1.6 mm) or
less of tread remaining.
You need a new tire if
You can see the indicators at three

or snagged deep enough to show cord
or fabric.

The tire has a bump, bulge or split.
The tire has a puncture, cut, or other
damage that can’t be repaired well
because of the size or location of the
damage.
Buying New Tires
To find out what kind and size of tires
you need, look at the Tire-Loading
Information label. The tires installed
on
your vehicle when it was new had a Tire
Performance Criteria Specification (TPC
Spec) number on each tire’s sidewall.
When you get new tires, get ones with that same TPC
Spec number. That way,
your vehicle will continue to have tires
that are designed to give proper
endurance, handling, speed rating,
traction, ride and other things during
normal service on your vehicle. If your
tires have
an all-season tread design, the
TPC number will be followed by a
“MS” (for mud and snow).
If you ever replace your tires with those
not having a TPC Spec number, make
sure they are the same size, load range,
speed rating and construction type (bias,
bias-belted
or radial) as your original
tires.
Mixing tires could cause you
- to lose control while driving.
I€ you mix tires of different sizes
or types (radial and bias-belted
tires), the vehicle may not handle
properly, and you could have a
crash. Be sure to use the same size
and type tires on all four wheels.
Uniform Tire Quality Grading
The following information relates to the
system developed by the United States
National Highway Traffic Safety
Administration which grades tires by
treadwear, traction and temperature

Service & Appearance Care
performance. (This applies only to
vehicles sold in the United States.)
Treadwear
The treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded
150 would
wear one and a half
(1 1/2) times as
well on the government course as a tire
graded
100. The relative performance of
tires depends upon the actual conditions
of their use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices and differences in road characteristics and climate.
Traction - A, B, C
The traction grades, from highest to
lowest are:
A, B, and C. They represent
the tire’s ability to stop on wet pavement
as measured under controlled conditions
on specified government test surfaces of
asphalt and concrete.
A tire marked C
may have poor traction performance.
Warning: The traction grade assigned to
this tire is based on braking
(straight-ahead) traction tests and does
not include cornering (turning) traction.
Temperature - A, B, C
The temperature grades are A (the
highest),
B, and C, representing the
tire’s resistance to the generation of heat and
its ability to dissipate heat when
tested under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperature can cause the
material
of the tire to degenerate and
reduce tire life, and excessive
temperature can lead
to sudden tire
failure. The grade
C corresponds to a
level of performance which all passenger
car tires must meet under the Federal
Motor Vehicle Safety Standard
No. 109.
Grades B and A represent higher levels
of performance on the laboratory test
wheel than the minimum required by
law.
Warning: The temperature grade for this
tire is established for a tire that is

properly inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either separately or in
combination, can cause heat buildup and
possible tire failure.
Those grades are molded on the
sidewalls of passenger car tires.
While the tires available as standard or
optional equipment on General Motors
vehicles may vary with respect to these
grades, all such tires meet General
Motors performance standards and have
been approved for use on General
Motors vehicles. All passenger type
(P metric) tires must conform to Federal
safety requirements in addition to these
grades.
Wheel Alignment and Tire Balance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to have
your wheels aligned again. However, if
you notice unusual tire wear
or your
vehicle pulling one way or the other, the
alignment may need to be reset. If you
notice your vehicle vibrating when
driving on a smooth road, your wheels
may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked
or badly rusted. If wheel nuts keep coming
loose, the wheel, wheel bolts,
and wheel nuts should be replaced.
If
the wheel leaks air out, replace it
(except some aluminum wheels, which
can sometimes be repaired). See your
Geo dealer if
any of these conditions
exist.
Your dealer will know the kind of wheel
you need.
If you need to replace any of your
wheels, wheel bolts, or wheel nuts,
replace them only with
new GM original
equipment parts. This way, you will be
sure to have the right wheel, wheel
bolts, and wheel nuts for your Tracker.

nuts on your vehicle can be

Always use the correct wheel,
wheel bolts, and wheel nuts for
replacement.

Aluminum Wheels
If your Geo has these, don’t use chrome
polish on them. Use wax after you clean
them. Also, don’t use abrasive cleaners or cleaning brushes on them
- you
could damage the protective coating.
If you have aluminum wheels,
don’t use an automatic car wa:
that has
hard silicon carbide
cleaning brushes. These brushes
can take off the protective coatinl
Weatherstrips
These are places where glass or metal
meets rubber. Silicone grease there will
make them last longer, seal better, and
not squeak. Apply silicone grease with a
clean cloth at least every six months.
Sheet Metal Damage
If your vehicle is damaged and requires
sheet metal repair or replacement, make
sure the body repair shop applies
anti-corrosion material to the parts
repaired or replaced to restore corrosion
protection.
Foreign Material
Calcium chloride and other salts, ice
melting agents, road oil and tar, tree
sap, bird droppings, chemicals from
industrial chimneys, and other foreign
matter can damage your vehicle’s finish
if they remain on painted surfaces. Use
cleaners
that are marked safe for painted
surfaces for these stains.
