If You’re Stuck: In Sand, Mud, Ice or
Snow
What you don’t want to do when your vehicle is stuck is
to spin
your wheels too fast. The method known as
“rocking” can help you get out when you’re stuck, but
you must use caution.
I NOTICE:
Spinning your wheels can destroy parts of your
vehicle as well as the tires. If you spin the wheels
too fast while shifting your transmission back
and forth, you can destroy your transmission.
For information about using tire chains on your vehicle,
see
‘“Tire Chains” in the Index.
ProCarManuals.com

Rocking your vehicle to get it out:
First, turn your steering wheel left and right. That will
clear the area around your front wheels. Then shift back
and forth between REVERSE (R) and
a forward gear (or
with a manual transmission, between FIRST (1) or
SECOND (2) and REVERSE (R)), spinning the wheels
as little as possible. Release the accelerator pedal while
you shift, and press lightly on the accelerator pedal
when the transmission is in gear. If that doesn’t get
you
out after a few tries, you may need to be towed out. Or,
you can use your recovery hooks, if your vehicle has
them.
If you do need to be towed out, see “Towing Your
Vehicle” in the
Index.
Using the Recovery Hooks
Your vehicle is equipped with recovery hooks. The
recovery hooks are provided at the front and rear of your
vehicle. You may need to use them if you’re stuck
off-road and need to be pulled to some place where
you
can continue driving.

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

Inflation - Tire Pressure
The Tire-Loading Information label which is on the
driver’s door shows the correct inflation pressures for
your tires, when they’re cold.
“Cold” means your
vehicle has been sitting for at least three hours or driven
no more than
a mile.
I
’ NOTICE:
Don’t let anyone tell you that underidation or
~ overinflation is all right. It’s not. If your tires don’t
~ have enough air (underinflation) you can get:
Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy.
If your tires have too much air (overinflation),
you can get:
Unusual wear
0 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.
How to Check
Use a good quality pocket-type gage to check tire
pressure. Simply looking at the tires will
not tell you the
pressure, especially if you have radial tires
-- which
may look properly inflated even
if they’re underinflated.
If your tires have valve caps, be sure to put them back on.
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.
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.
ProCarManuals.com

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

After the tires have Deen rotated, adjust the front and
rear inflation pressures as shown on the Tire-Loading
Information label. Make certain that all wheel nuts are
properly tightened. See “Wheel
Nut Torque” in the
Index.

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. These
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
or corroded.
If wheel nuts keep coming loose, the wheel,
wheel bolts, and wheel nuts should be replaced.
If the
wheel leaks air, replace it (except some aluminum
wheels, which can sometimes be repaired). See your
Chevrolet/Geo dealer
if any of these conditions exist.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same load carrying
capacity, diameter, width, offset, and be mounted the
same way as the one it replaces.
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 Geo
model. I NOTICE:
The wrong wheel can also cause problems
with bearing life, brake cooling,
speedometer/odometer calibration, headlamp aim, bumper height, vehicle ground clearance,
and tire or tire chain clearance to the body and
chassis.
