Four-wheel Drive How to Check Lubricant
Most lubricant checks in th’is section also apply to
four-wheel-drive vehicles. However,
they have two
additional systems that need lubrication.
Transfer Case
When to Check and Change Lubricant
Refer to the Maintenance Schedule to deternine how
often to check the lubricant and when to change it. See
“Scheduled Maintenance
Services” 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.

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
“Periodic Maintenance Inspections” and “Scheduled
Maintenance Services” in the Index.
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 (1 2 mm) below the filler plug hole.

Brake Wear
Your Geo has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that make a
high-pitched warning sound when the brake pads are
wor~ and new pads are needed.
The sound may come and
go or be heard all the time your vehicle is moving (except
when you are pushing
on the brake pedal firmly).
The brake wear warning sound means that sooner
or later your brakes won’t work
well. That could
lead
to an accident. When you hear the brake
wear warning
sound, have your vehicle serviced.
I NOTICE: I
Continuing to drive with worn-out brake pads
could result
in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly applied.
This does not mean something is wrong with
your brakes,
Free movement of brake calipers and properly torqued
wheel nuts are necessary to help prevent brake pulsation.
When tires are rotated, inspect brake calipers for
movement, brake pads for wear, and evenly torque wheel
nuts
in the proper sequence to GM specifications.
Your rear drum brakes don’t have wear indicators, but
if
you ever hear a rear brake rubbing noise, have the rear
brake
linings inspected. Also, the rear brake drums
should be removed and inspected each time the tires are
removed for rotation or changing. When you have the
front brakes replaced, have the rear brakes inspected,
too.
Brake linings should always be replaced as complete
axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height,
or if there is a rapid increase in pedal
travel. This could
be a sign of brake trouble.

We don’t make tires. Your new Geo comes with
high-quality tires made by a leading tire manufacturer.
If you ever have questions about your tire warranty and
where to obtain service, see your Geo Warranty booklet
for details.
A CAUTION:
Poorly maintained and improperly used
are dangerous.

overheating as a result of too
much friction.
You could have an air-out and a serious
accident. See “Loading
Your Vehicle” in
the Index.
Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are
cold.
Overinflated tires are more likely to be
cut, punctured or broken by a sudden
impact
-- such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn,
old tires can cause accidents. If your
tread
is badly worn, or if your tires have
been damaged, replace them.

Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
(IO OOO ro 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.

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 schc . [led
rotation intervals.
When rotating
your tires, always use one of the correct
rotation
patterns shown here.

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 an “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. If
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.
Using tires of different sizes may also cause
damage
to your vehicle. Be sure to use the same
size and type tires on all 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 performance.
(This applies only to vehicles sold
in the United States.)
The grades are molded on the sidewalls
of most
passenger car tires. The Uniform Tire Quality Grading
system does not apply to deep tread, winter-type snow
tires, space-saver or temporary use spare tires, tires with
nominal
rim diameters of 10 to 12 inches (25 to 30 cm),
or to some limited-production tires.

While the tires available on General Motors passenger
cars and light trucks
may vary with respect to these
grades, they must also conform to Federal safety
requirements and additional General Motors Tire
Performance Criteria
(TPC) standards.
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 nom 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, and 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 (straightahead) 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 perfol’mance
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.

Finish Damage
Any stone chips, fractures or deep scratches in the finish
should be repaired right away. Bare metal
will corrode
quickly and may develop into a major repair expense.
'Miinor chips and scratches can be repaired with touch-up
materials available from your dealer or other service
outlets. Larger areas of finish 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,
accelerated corrosion (rust)
can occur on the underbody
parts such as fuel lines, frame, floor pan and exhaust
system even though they have corrosion protection.
At least every spring, flush these materials from the
underbody with plain water. Clean any areas where mud
and
other debris can collect. Dirt packed in closed areas
of the frame should be loosened before being flushed.
Your dealer or an underbody vehicle 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 your vehicle. This damage
can take two forms: blotchy, ringlet-shaped
discolorations, and small irregular dark spots etched into
the paint surface.
Although
no defect in the paint job causes this, Geo
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 first.
