Cruise Control (If Equipped)
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot on
the accelerator. This can really help on long trips. Cruise
control does not work at speeds below about
25 mph
(40 kmh). When you
apply your brakes, or push the clutch pedal
if you have a manual transmission, the cruise control
shuts
off.
Cruise control can be dangerous where you
can’t drive safely at a steady speed.
So,
don’t use your cruise control on winding
roads
or in heavy traffic.
slippery roads. On such roads,
fast changes
in tire traction can cause needless wheel
spinning, and you could lose control. Don’t
use cruise control on slippery roads.

Here’s how anti-lock works. Let’s say the road is wet.
You’re driving safely. Suddenly an animal jumps out in
front of you.
You slam on the brakes. Here’s what happens with ABS.
A computer senses that wheels are slowing down. If one
of the wheels is about to stop rolling, the computer will
separately work the brakes at each front wheel and at the
rear wheels. The anti-lock system can change the brake pressure
faster than any
dnver could. The computer is
programmed to make the most of available tire and
road conditions.
You can steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates or
wheel speed and controls braking pressure accordingly.

Remember: Anti-lock doesn’t change the time you need
to get your foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle in
front
of you, you won’t have time to apply your brakes
if that vehicle suddenly slows or
stops. Always leave
enough room up ahead to stop, even though you have
anti-lock brakes.
Using Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down
and let anti-lock work for
you. You may feel the system
working, or
you may notice some noise, but this is normal.
ABS
ACTIVE
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
this light will come on. See
“Anti-Lock Brake System
Active Light” in
the Index.
Braking in Emergencies
At some time, nearly every driver gets into a situation
that requires hard braking.
If you have anti-lock, you can steer and brake at the
same time. However,
if you don’t have anti-lock, your
first reaction
-- to hit the brake pedal hard and hold it
down
-- may be the wrong thing to do. Your wheels
can stop rolling. Once they do, the vehicle can’t respond
to your steering. Momentum will carry it in whatever
direction it was headed when the wheels stopped rolling.
That could be off the road, into the very thing you were
trying to avoid, or into traffic.
If you don’t have anti-lock, use a “squeeze” braking
technique. This will give you maximum braking while
maintaining steering control.
You do this by pushing on
the brake pedal with steadily increasing pressure.
In
an emergency, you will probably want to squeeze the
brakes hard without locking the wheels. If
you hear or
feel the wheels sliding, ease
off the brake pedal. This
will help you retain steering control. (If you
do have
anti-lock, it’s different: see “Anti-Lock Brakes” in
the Index.)
In many emergencies, steering can help you more than
even the very best braking.

Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
Steering Tips
Driving on Curves
It’s important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here’s why:
Experienced driver or beginner, each of us is subject to
the same laws
of physics when driving on curves. The
traction
of the tires against the road surface makes it
possible for the vehicle to change its path when you turn
the front wheels. If there’s no traction, inertia will keep
the vehicle going
in the same direction. If you’ve ever
tried to steer a vehicle on wet ice, you’ll understand this.
The traction you can get in a curve depends on the
condition of your tires and the road surface, the angle at
which the curve
is banked, and your speed. While you‘re
in a curve, speed is the one factor you can control. Suppose you’re steering through
a sharp curve. Then you
suddenly apply the brakes. Both control systems
-- steering
and braking
-- have to do their work where the tires meet
the road. Unless you have four-wheel anti-lock brakes,
adding the hard braking can demand too much of those
places. You can lose control.
The same thing can happen
if you’re steering through a
sharp curve and you suddenly accelerate. Those two
control systems
-- steering and acceleration -- can
overwhelm those places where the tires meet the road
and make you lose control.
What should
you do if this ever happens? Ease up on the
brake or accelerator pedal, steer the vehicle the way
you
want it to go, and slow down.
Speed limit signs near curves warn that you should
adjust your speed. Of course, the posted speeds are
based
on good weather and road conditions. Under less
favorable conditions you’ll want to go slower.
If you need to reduce your speed as you approach a
curve, do
it before you enter the curve, while your front
wheels are straight ahead.
Try to adjust your speed
so you can “drive” through the
curve. Maintain
a reasonable, steady speed. Wait to
accelerate
until you are out of the curve, and then
accelerate gently into the straightaway.

Steering in Emergencies
There are times when steering can be more effective
than braking. For example,
you come over a hill and
find a truck stopped in your lane, or a car suddenly pulls
out from nowhere, or
a child darts out from between
parked cars and stops right in front of you. You can
avoid these problems by braking
-- if you can stop in
time. But sometimes you can’t; there isn’t room.
That’s the time for evasive action
-- steering around
the problem.
Your Geo can perform very well in emergencies like
these. First apply your brakes
-- but, unless you
have anti-lock, not enough to lock your wheels. (See
“Braking in Emergencies’’ earlier in this section.) It
is
better to remove as much speed as you can from a
possible collision. Then steer around the problem, to the
left or right depending on the space available. An
emergency like this requires close attention and a
quick decision. If you are holding the steering wheel at
the recommended 9 and 3 o’clock positions, you can
turn
it a full 180 degrees very quickly without removing
either hand. But you have
to act fast, steer quickly, and
just as quickly straighten
the wheel once you have
avoided the object.
The fact that such emergency situations are always
possible
is a good reason to practice defensive driving at
all times and wear safety belts properly.

Off-Road Recovery
You may find sometime that your right wheels have
dropped off the edge
of a road onto the shoulder while
you’re driving.
OFF-ROAD RECOVERY
c;‘ LEFT APPROX. QUARTERTURN
If the level of the shoulder is only slightly below the
pavement, recovery should be fairly easy. Ease
ofc the
accelerator and then, if there
is nothing in the way, steer so
that your vehicle straddles the edge of the pavement. You
can
turn the steering wheel up to one-quarter turn until the
right front tire contacts the pavement edge. Then
turn your
steering wheel to go straight down the roadway.
Passing
The driver of a vehicle about to pass another on a
two-lane highway waits for just the right moment,
accelerates, moves around
the vehicle ahead, then goes
back into the right lane again.
A simple maneuver?
Not necessarily! Passing another vehicle on a two-lane
highway
is a potentially dangerous move, since the
passing vehicle occupies
the same lane as oncoming
traffic for several seconds.
A miscalculation, an error in
judgment, or
a brief surrender to frustration or anger can
suddenly put the passing driver face to face with the
worst of all traffic accidents
-- the head-on collision.
So here are some tips for passing:
0 “Drive ahead.” Look down the road, to the sides and to
crossroads for situations that might affect your passing
patterns. If you have any doubt whatsoever about
making
a successful pass, wait for a better time.
Watch for traffic signs, pavement markings and lines.
If you can see
a sign up ahead that might indicate a
turn or an intersection, delay your pass. A broken
center line usually indicates it’s all right
to pass
(providing the road ahead is clear). Never cross a solid
line on your side of the lane or a double solid line,
even if the road seems empty of approaching traffic.

Loss of Control
Let’s review what driving experts say about what
happens when the three control systems (brakes, steering
and acceleration) don’t have enough friction where the
tires meet the road to do what the driver has asked.
In any emergency, don’t give up. Keep trying to steer and
constantly seek an escape route or area
of less danger.
Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not
“overdriving” those conditions. But skids are
always possible.
The three types of skids correspond to your Geo’s three
control systems.
In the braking skid, your wheels aren’t
rolling.
In the steering or cornering skid, too much speed
or steering
in a curve causes tires to slip and lose
cornering force. And in the acceleration skid, too much
throttle causes the driving wheels to spin.
A cornering skid and an acceleration skid are best
handled by easing your foot off the accelerator pedal.
If your vehicle starts to slide, ease your foot off
the
accelerator pedal and quickly steer the way you want the vehicle
to go. 11 you
start steering quickly enough, your
vehicle may straighten out. Always be ready for a
second skid if it occurs.
Of course, traction
is reduced when water, snow, ice,
gravel or other material is on
the road. For safety, you’ll
want to slow down and adjust your driving to these
conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on
a surface with reduced traction, try
your best to avoid sudden steering, acceleration or
braking (including engine braking by shifting to a lower
gear). Any sudden changes could cause the tires to slide.
You may not realize the surface is slippery until your
vehicle is skidding. Learn to recognize warning clues
--
such as enough water, ice or packed snow on the road to
make a “mirrored surface’’
-- and slow down when you
have any doubt.
If you have the anti-lock braking system, remember:
It helps avoid only the braking skid. If you do not have
anti-lock, then
in a braking skid (where the wheels are
no longer rolling), release enough pressure on the brakes
to get
the wheels rolling again. This restores steering
control. Push the brake pedal down steadily when you
have to stop suddenly.
As long as the wheels are rolling,
you will have steering control.

Driving Guidelines
This multipurpose passenger vehicle is defined as a
utility vehicle in Consumer Information Regulations
issued by the National Highway Traffic Safety
Administration (NHTSA) of the United States
Department of Transportation. Utility vehicles have
higher ground clearance and a narrower track to make
them capable of performing in a wide variety
of off-road
applications. Specific design characteristics give them a
higher center
of gravity than ordinary cars. An
advantage of the higher ground clearance is a better
view of the road allowing you
to anticipate problems.
They are not designed for cornering at the same speeds
as conventional two-wheel-drive vehicles any more than
low-slung sports cars are designed to perform
satisfactorily under off-road conditions. If at all
possible, avoid sharp turns or abrupt maneuvers.
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.
Surfaces 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.
