1993 Oldsmobile Cutlass Supreme Owner's Manuals

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.
CAUTION
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. A brief mechanical noise is
normal. This is the
ABS system testing
itself.
You also may hear a clicking
noise as
you accelerate after a hard
stop.
Disc Brake Wear lndicafors
Your Oldsmobile has four-wheel disc
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.)
zontinuing to drive with worn-01

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.
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.
Brake Adjustment
Every time you make a moderate brake
stop, your disc 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.

Power Seering
If you lose power steering assist
became the engine stops or the system
fails to function, you can steer but it
will take much more effort.

Steering Tips-Driving on Curves
154
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 jaws 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 banlted, 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 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.
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.

I 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-but unless you have anti-
lock, not enough to lock your 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
quicldy 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.

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.
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 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.
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 malting a
successful pass, wait for a better time.
I

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
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.
If you suspect that the driver of the
vehicle you want to pass isn’t aware
of your presence, tap the horn a
couple of times before passing. Or,
you can use flash-to-pass. See the
Index under Flash-to-Pass.
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.
I (providing the road ahead is clear).
When it loolts 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.
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 braldng (including engine braking by shifting to a
lower gear). Any sudden changes could
