Anti-Lock Brakes (ABS) You slam on the brakes. Here’s what
Your vehicle has an advanced electronic happens with
ABS.
braking system that can help you keep it A computer senses that a rear wheel is
under control. When you stag your
-
vehicle and begin to drive away, you
may hear a momentary motor or
clicking noise. The ABS motor comes
on momentarily when the vehicle
reaches
8 mph (12 km/h). This is the
ABS system testing itself.
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. slowing
down. The computer works the
brakes at the rear wheels. It is
programmed to make the most
of
available tire and road conditions.
As you brake, your computer keeps
receiving updates on rear wheel speed
and controls braking pressure
accordingly.

up to the brake pedal.

To Use Anti-Lock:
Use rear wheel anti-lock like regular
brakes.
You may feel the brakes vibrate,
or you may notice some noise outside
your vehicle, but this is normal. Let
anti-lock work for you, but remember:
Your front wheels can still stop rolling.
If that happens, release enough pressure
on the brakes to get the wheels rolling
again
so that you can steer.
With the four-wheel-drive option, you
won't have anti-lock braking when you
shift into four-wheel drive. But you will
have regular braking. When you shift
back into two-wheel drive, you will
have anti-lock again.

Disc Brake Wear Indicators
Your Geo has front disc and rear drum
brakes.
Disc brake pads have built-in wear
worn 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).

Braking in Emergencies
At some time, nearly every driver gets
into a situation that requires hard
braking.
You have the rear wheel
anti-lock braking system. Your front
wheels can stop rolling when you brake
very hard. 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.
So, 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. When
you do, you can maintain steering
control. In many emergencies, steering
can help you more than even the very
best braking.
Steering
Power Steering
If you lose power steering assist because
the engine stops or the system fails to
function, 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
ProCarManuals.com

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.
ProCarManuals.com

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.
ProCarManuals.com

Depending on your speed, this can be
rather violent for an unprepared driver.
This is one of the reasons driving
experts recommend that you use your
safety belts and keep both hands on the
steering wheel.
The fact that such emergency situations are always possible is a good reason to
practice defensive driving at all times. Off-Road Recovery
You may find sometime that your right
wheels have dropped off the edge of a
road onto the shoulder
(A) while you’re
driving.
If the level of the shoulder is only
slightly below the pavement, recovery
should be fairly easy. Ease
off 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
1/4
turn (B) until the right front tire contacts
the pavement edge. Then turn your
steering wheel to go straight down the
roadway.
If the shoulder appears to be about four
inches
(100 mm) or more below the
pavement,
this difference can cause
problems. If there is not enough room to
pull entirely onto the shoulder and stop,
then follow the same procedures. But
if
the right front tire scrubs against the
side of the pavement, do NOT steer
more sharply. With too much steering
angle, the vehicle may jump back onto
the road with
so much steering input
that it crosses over into the oncoming
traffic before you can bring it back
under control. Instead, ease
off again on
the accelerator and steering input,
straddle the pavement once more, then
try again.

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
