1995 Oldsmobile Achieva brake

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 driver 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 on
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. 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.

To Use 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.
Braking in Emergencies
Use your anti-lock braking system when you need to.
With anti-lock, you can steer and brake at the same
time.
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 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 YOLI 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 accelerate. Both control systems
--
steering and acceleration -- have to do their work where
the tires meet the road. Adding the sudden acceleration
can demand too much of those places. You can lose
control.
What should you do
if this ever happens? Ease up on the
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.
4-8

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.
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
YOLI have to act fast, steer quickly, and
just as quickly straighten the wheel once you
have
avoided the object.
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 Oldsmobile can perform very well in emergencies
like these. First apply your brakes. 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. 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.
4-9

Do not get too close to the vehicle you want to pass
while you’re awaiting an opportunity. For one thing,
following too closely reduces your area
of vision,
especially
if you’re following a larger vehicle. Also,
you won’t have adequate space if the vehicle ahead
suddenly slows or stops. Keep back a reasonable
distance.
When it looks like a chance to pass is coming up,
start
to accelerate but stay in the right lane and don’t
get too close. Time your move
so you will be
increasing speed as the time comes to move into the
other lane. If the way is clear to pass, you will have a
“running start” that more than makes up
for the
distance you would lose by dropping back. And if
something happens
to cause you to cancel your pass,
you need only slow down and drop back again and
wait for another opportunity.
If other cars are lined up to pass a slow vehicle, wait
your turn. But take care that someone isn’t trying to
pass you as you pull out
to pass the slow vehicle.
Remember
to glance over your shoulder and check
the blind spot.
0 Check your mirrors, glance over your shoulder, and
start your left lane change signal before moving out
of the right lane to pass. When you are far enough
ahead
of the passed vehicle to see its front in your
inside mirror, activate your right lane change signal
and move back into the right lane. (Remember that
your right outside mirror is convex. The vehicle you
just passed may seem to be farther away from you
than
it really is.)
Try not to pass more than one vehicle at a time on
two-lane roads. Reconsider before passing the next
vehicle.
0 Don’t overtake a slowly moving vehicle too rapidly.
Even though the brake lamps are not flashing, it may
be slowing down or starting to turn.
If you’re being passed, make it easy for the
following driver to get ahead
of you. Perhaps you
can ease a little to the right.

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
Oldsmobile’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. If
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.
Remember: Any anti-lock brake system
(ABS) helps
avoid only
the braking skid.

Rain and wet roads can mean driving trouble. On a wet
road you can’t stop, accelerate or turn as well because
your tire-to-road traction isn’t as good as on dry roads.
And, if your tires don’t have much tread left, you’ll get
even less traction. It’s always wise
to go slower and be
cautious if rain starts to fall while
you are driving. The
surface may get wet suddenly when your reflexes are
tuned for driving on dry pavement.
The heavier the rain, the harder it is to see. Even if your
windshield wiper blades are
in good shape, a heavy rain
can make it harder to
see road signs and traffic signals,
pavement markings, the edge of the road, and
even
people walking.
It’s wise to keep your wiping equipment in good shape
and keep your windshield washer tank filled. Replace
your windshield wiper inserts when they show signs
of
streaking or missing areas on the windshield, or when
strips of rubber start to separate from the inserts. Driving
too fast through large water puddles or even
going through some car washes can cause problems, too.
The water may affect your brakes. Try to avoid puddles.
But if you can’t, try to slow down before you
hit them.

Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system and
transaxle. These parts can work hard on mountain
roads.
Know how to go down hills. The most important
thing to know is this:
let your engine do some of the
slowing down. Shift
to a lower gear when you go
down a steep or long hill.
4-21

What’s the worst time for this? “Wet ice.” Very cold
snow or ice can be slick and hard to drive on. But wet
ice can be even more trouble because it may offer the
least traction
of all. You can get “wet ice” when it’s
about freezing
(32°F; OOC) and freezing rain begins to
fall.
Try to avoid driving on wet ice until salt and sand
crews 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 the
anti-lock braking system, you’ll want to begin stopping
sooner than you would on dry pavement. See
“Anti-Lock’’ in the Index.
0 Allow greater following distance on any slippery
road.
Watch for slippery spots. The road might be fine
until you hit a 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 surface 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 steering maneuvers.
