Your Driving and the Road
As with other vehicles of this type, failure
to operate this vehicle correctly may
result
in loss of control or vehicle
rollover.
Off-Road Driving with
Your Geo Four-wheel
Drive Vehicle
This off-road guide is for vehicles that
have four-wheel drive.
Also, see “Anti-lock Brakes”
in the Index.
If your vehicle doesn’t have four-wheel
drive, you shouldn’t drive off-road unless
you’re
on a level, solid surface.
Off-road driving can be great fun. But
it
does have some definite hazards. The
greatest of these is the terrain itself.
“Off-roading” means
you’ve left the great
North American road system behind.
Traffic lanes aren‘t marked. Curves aren’t
banked. There are no road signs. Surfwes
can be slippery, rough, uphill
or downhill.
In short, you’ve gone right back to nature.
Off-road driving involves
some new
skills. And that’s
why it’s very important
that
you read this guide. You’ll find many
driving tips and suggestions. These
will
help make your off-road driving safer and
more enjoyable.
=. .lo8
Before You Go Off-Roading
There are some things to do before you
go out. For example, be sure to have all
necessary maintenance and service work
done. Be sure you read all the information
about your four-wheel drive vehicle in
this manual. Is there enough fuel? Is the
spare tire
fully inflated‘? Are the fluid
levels up where they should
be‘? What are
the local laws
that apply to off-roacting
where you’ll be driving?
If you don’t
know, you should check with law
enforcement people
in the area. Will you
be on someone’s private land?
If so, be
sure
to get the necessary permission.
Loading Your Vehicle for Off-Road
Driving
There are some important things to
remember
about how to load your
vehicle. The heavies1 things should
be on the
load floor and forward of your rear
axle. Put heavier items
as far forward
as you can.
e Be sure the load is secured properly,
so driving on the off-road terrain
doesn’t
toss things around.
You’ll find other important information in
this manual. See “Vehicle Loading” and
”Tires”
in the Index.

Include an ice scraper7 a small brush or
broom. a supply of windshield washer
fluid,
a rag, some winter outer clothing, a
small shovel, a flashlight, a red cloth, and
a couple of reflective warning triangles.
And,
if you will be driving under severe
conditions, include
:I small bag of sand, ;I
piece of old carpet or a couple of burlap
bags to
help provide traction. Be sure yo11
properl}, secure these item in your
vehicle.
Driving on Snow or Ice
Most of the time. those placcs where your
tires meet the road probably have good
traction.
Howe\w-.
it’ thcrc is snow or ice between
your tires antl the road, you can Iwve ;I
very slippery situation. You‘ll have ;t lot
less traction or “grip“ and will need to be
very careful.
What‘s the worst time
for this’? “Wet ice.”
Very cold snow
or ice can be slick and
hurd to drive on. Rut wet ice can be even
more trouble because
it nlay offer the
least traction
of all. You can get ”wet ice”
when it’s about freezing
(32°F; 0°C) and
freezing rain begins to fall. Try to avoid
hiving on wet ice
until salt and sand
:rews
can get there. Whatever the condition
- smooth ice.
packed. blowing or loose snow
- drive
with caution.
Accelerate gently. Try not
to break the
fragile traction. If you accelerate too fast,
the drive wheels will spin and polish the
surface under the tires even more.
Your anti-lock brakes improve your
ability
to make a hard stop on a slippery
road. Even though you have
an anti-lock
braking system.
you’ll want to begin
stopping sooner than
you would on dry
pavement.
See “Anti-lock” in the Index.

Allow greater following distance on
any slippery road.
Watch for slippery spots. The road
might be fine
until you hit H spot that’s
covered with ice.
On an otherwise
clear road. ice patches may appear
in shaded areas where the sun can’t
reach: around clumps
of trees. behind
buildings, or under bridges.
Sometimes the surftlce
of a curve or
an overpass may remain icy when the
surrounding roads are clear.
If you
see a patch of ice ahead of you, brake
before you are on
it. Try not to brake
while
you’re actually on the ice, and
avoid sudden steerins maneuvers.

distance is less than 12 inches, take
the foot off the trailer tongue.
Will you have to make any holes
in
the body of your vehicle when you
install a trailer hitch?
If you do, then
be sure
to seal the holes later when
you remove the hitch. If you don't
seal them, deadly carbon monoxide
(CO) from your exhaust can get into
your vehicle (see "Carbon Monoxide"
in the Index). Dirt and water can, too.
Safety Chains
You should always attach chains between
your vehicle and your trailer. Cross the
safety chains under the tongue of the
trailer
so that the tongue will not drop to
the road if
it becomes separated from the
hitch. Instructions about safety chains
may be provided by the hitch
manufacturer
or by the trailer
manufacturer. Follow the manufacturer's
recommendation
for attaching safety
chains. Always leave just enough slack
so
you can turn with pour rig. And, never
allow safety chains
to drag on the ground.
Trailer Brakes
If your trailer weighs more than 1,000
pounds (450 kg) loaded, then it needs its
own brakes -and they must be adequate.
Be sure
to read and follow the instructions
for the trailer brakes so you'll be able to
install, ad-just and maintain them properly.
Don't tap into your vehicle's brake
system
if the trailer's brake system
will use more than 0.02 cubic inch
(0.3 cc) of fluid from your vehicle's
master cylinder.
If it does. both
systems won't work well. You could
even lose your brakes.
Will the trailer brake parts take
3,000
psi (20 650 kPa) of pressure? If not,
the trailer brake system must not be
used
with your vehicle.
If everything checks out this far. then
make the brake fluid tap at the port on
the master cylinder that sends fluid
to
the rear brakes. But don't use copper
tubing for
this. If you do, it will bend
and finally break off. Use steel brake
tubing.
Driving with a Trailer
Towing a trailer requires a certain amount
of experience. Before setting out for the
open road, you'll want
to get to know
your rig. Acquaint yourself
with the feel
of handling and braking with the added
weight
of the trailer. And always keep in
mind that the vehicle you are driving is
now a good deal longer and not nearly so
responsive as your vehicle is by itself.
Before you start, check the trailer hitch
and platform. safety chains, electrical
contwxtor. lights, tires and mirror
adjustment. If the trailer has electric
brakes, start your vehicle and trailer
moving and then apply the trailer brake
controller by hand to be sure the brakes
are working. This lets you check your
electrical connection
at the same time.
During your trip, check occasionally to be
sure that the load is secure. and that the
lights and any trailer brakes are
still
working.
Following Distance
Stay at least twice as far behind the
vehicle ahead as
you would when driving
your vehicle without
a trailer. This can
help you avoid situations that require
heavy braking and sudden turns.
Passing
You'll need more passing distance up
ahead when you're towing a tnliler. And.
because you're
B good deal longer, you'll
need to go much farther beyond the

Service and Appearance Care
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.
NOTICE:
The wrong wheel can also cause
problems
with bearing life, brake
cooling, speedometer/odometer
calibration, headlight aim, bumper
height, vehicle ground clearance,
and
tire or tire chain clearance to the
body and chassis.
Used Replacement Wheels
A CAUTION:
Putting a used wheel on your vehicle
is dangerous. You can’t know how
it’s been used or how many miles it’s
been driven. It could
fail suddenly
and cause an accident.
If you have
to replace a wheel
use a new GM
original equipment wheel.
Tire Chains
NOTICE:
Use tire chains only where legal and
only when you must. Use only SAE
Class “S” type chains that are the
proper size for your tires. Install them
on the tires of the drive axle (four-
wheel drive vehicles can use chains
on both axles). Tighten them
as
tightly as possible with the ends
securely fastened. Drive slowly and
follow the chain manufacturer’s
instructions.
If you can hear the
chains contacting your vehicle, stop
and retighten them.
If the contact
continues, slow down until
it stops.
Driving too fast with chains
on will
damage your vehicle.
