If you keep pace with the traffic and
allow realistic following distances, you
will eliminate a lot
of unnecessary
braking. That means better braking and longer brake life.
If your engine ever stops while you're
driving, brake normally but don't
pump your brakes.
If you do, the pedal
may get harder to push down. If your
engine stops, you will still have some
power brake assist. But you will use it
when you brake. Once the power
assist is used up, it may take longer to
stop and the brake pedal will be
harder to push.

When you start your vehicle and begin
to drive away you may hear a
momentary motor or clicking noise

also hear this
noise if you leave the ignition in the
Run position for about four seconds
before starting the vehicle.)
If you have your foot on the brake
pedal, this check won’t happen until
the vehicle goes about
4 mph (6 Wh)
or until you take your foot off the
brake pedal.
You’ll also hear a clicking noise the
next time the vehicle goes about
4
mph (6 Wh).
If there’s a problem with the anti-lock
brake system, the anti-lock brake system

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. When
you start your vehicle and begin to drive
away, you may notice that your brake
pedal moves a little
while this is going
on.

Disc Brake Wear Indicators
Your Oldsmobile has front disc brakes
and rear drum brakes. Disc brake pads
have built-in wear indicators that make a
high-pitched warning sound when the
brake pads are 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).

Disc Brake Wear Indicators (CONT.)
Some driving conditions or climates
may cause a brake squeal when
the
brakes are first applied or lightly
applied. This does not mean something
is wrong with your brakes.
Rear Drum Brakes
Your rear drum brakes don’t have wear
indicators, but if
you ever hear a rear
brake rubbing noise, have the rear brake
linings inspected. Also, the rear brake
drums should be removed and inspected
each time the tires are removed for
rotation or changing. When you have the
front brakes replaced, have the rear
brakes inspected, too.
Brake linings should always be replaced
as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does
not return to normal height, or if there
is
a rapid increase in pedal travel. This
could be a sign
of brake trouble.
ProCarManuals.com

Brake Adjustment
Every time you make a brake stop, your
brakes adjust for wear.
If you rarely
make a moderate or heavier stop, then
your brakes might not adjust correctly.
If you drive in that way, then-very
carefully-make a few moderate brake
stops about every
1,000 miles (1 600 km),
so your brakes will adjust properly.
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.
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
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 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 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.
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.

1 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.
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. 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.

Ofi-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.
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
?4 turn
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
behre 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.
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:
“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.
ProCarManuals.com

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.
vehicle you want to pass isn’t aware of
your presence, tap the horn a couple
of times before passing.
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.
If you suspect that the driver of the
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.

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 (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.
E 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
