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
i and braking - have to do their work where the tires
meet the road. Adding
the hard braking can demand too much
at 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? Let 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.

Your Driving and the Road
When you drive into a curve at night,
it’s harder to see the road ahead of you
because it bends away from the straight
beams of your lights. This is one good
reason to drive slower.

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 not enough to lock your
front wheels. 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.
You
must then be prepared to steer back to
your original lane and then brake to a
controlled stop.

vehicle too rapidly. Even though the

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 (as when you turn
a corner on a wet, snow- or ice-covered
road), ease your foot off the accelerator

pedal as soon as you feel the vehicle
start to slide. Quickly steer the way you
want the vehicle to go. If you start
steering quickly enough, your vehicle
will straighten out. As
it does, straighten
the front wheels.
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. Remember: the
rear wheel anti-lock
braking system (RWAL) helps avoid
only a rear braking skid. In a braking
skid (where the front wheels are no
longer rolling), release enough pressure
on the brakes to get the front wheels
rolling again. This restores steering
control. Push the brake pedal down
steadily when you have to stop
suddenly. As long as the front wheels
are rolling, you will have steering
control. Steer the way you want to go.

Driving Guidelines
... 140
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.

If your vehicle doesn’t have four-wheel

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.

Ease up on your speed as you
approach the top
of the hill.
Attach a flag to the vehicle to make
you more visible to approaching
traffic on trails or hills.
Sound the horn as you approach the
top of the hill to let opposing traffic
know you’re there.
Use your headlights even during the
day. They make you more visible to
oncoming traffic.
CAUTION
A Driving to the top (crest) of a
hill at full speed can cause an
accident. There could be a
drop-off, embankment, cliff, or
even another vehicle. You could
be seriously injured or killed. As
you near the top of a hill, slow
down and stay alert.
I
Q: What should I do if my vehicle
stalls,
or is about to stall, and I
can’t make it up the hill?
A: If this happens, there are some
things you-should do, and there are
some things you must not do. First,
here’s what you
should do:
Push the brake pedal to stop
the
vehicle and keep it from rolling
backwards. Also, apply the parking
brake.
If your engine is still running, shift
the transmission into reverse, release
the parking brake, and slowly back
down the hill in reverse.
ProCarManuals.com

If your engine has stopped running,
you’ll need to restart
it. With the
brake pedal depressed and the
parking brake still applied, shift the
transmission
to P (Park) (or, shift to
Neutral if your vehicle has a
manual transmission) and restart the
engine. Then, shift to reverse,
release the parking brake, and
slowly back down the hill in
reverse.
As you are backing down the hill,
put your
left hand on the steering
wheel at the
12 o’clock position.
This way, you’ll be able
to tell if
your wheels are straight or turned to
the left or right as you back down. Here
are some things you
must not do
if you stall, or are about to stall, when
going up
a hill.
Never attempt to prevent a stall by
shifting into
N (Neutral) (or
depressing the clutch, if you have a
manual transmission)
to “rev-up” the
engine and regain forward
momentum. This won’t work. Your
vehicle will roll backwards very
quickly and you could go out of
control.
Instead, apply the regular brake to stop
the vehicle. Then apply the parking
brake. Shift into reverse, release the
parking brake, and slowly back down.
Never attempt to turn around if you
are about to stall when going up a
hill.
If the hill is steep enough to
stall your vehicle, it’s steep enough
to cause you to roll over if you turn
around. If you can’t make it up the
hill, you must back down the hill.
Q: Suppose, after stalling, I try to
back down the hill and decide
I
just can’t do it. What should I do?
A: Set the parking brake, put your
transmission
in P (Park) (or the

manual transmission in first gear),
and turn off the engine. Leave the
vehicle and
go get some help. Exit
on the uphill side and stay clear of
the path the vehicle would take if it
rolled downhill.
Do not shift the
transfer case to
N (Neutral) when
you leave the vehicle. Leave it in
some gear.
A
Shifting the transfer case to
N (Neutral) can cause your
vehicle to roll even if the
transmission is in
P (Park) (or, if
you have the manual transmission,
even if you’re in gear). This is
because the
N (Neutral) position
on the transfer case overrides the
transmission.
If you are going to
leave your vehicle, set the parking
brake and shift the transmission to
P (Park) (or, put your manual
transmission in first gear). But
do I
not shift the transfer case to the N
(Neutral) position. Leave the
transfer case
in the 2H, 4H, or 4L I position.
Driving Downhill
When off-roading takes you downhill,
you’ll want to consider
a number of
things:
How steep is the downhill? Will I b
able to maintain vehicle control?
What’s the surface like? Smooth?
Rough? Slippery? Hard-packed dirt?
Gravel?
Are there hidden surface obstacles?
Ruts? Logs? Boulders?
What’s at the bottom of the hill? Is
there a hidden creek bank or even a
river bottom with large rocks?
