Cruise Control (Option)
I
A CAUTION:
Cruise Control can be dangerous where
you can’t drive safely at
a steady speed.
So, don’t use your Cruise Control on
winding roads or in heavy traffic.
Cruise Control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause needless
wheel spinning, and you could lose
control. Don’t use Cruise Control
on
slippery roads.
With Cruise Control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot on
the accelerator. This can really help on long trips. Cruise
Control
does not work at speeds below about 25 mph
(40 h/h).
When you apply your brakes, the Cruise Control shuts
off.

If there’s a problem with the anti-lock brake system, the
anti-lock brake system warning light will stay
on or
flash.
See “Anti-lock Brake System Warning Light”
in the
Index.
I
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. The
computer separately works the brakes at each front
wheel and at the rear wheels.
141
ProCarManuals.com

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.
/A 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
cvddenly
slows or stops. Always leave enough
luom 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 also may hear a
clicking noise as
you accelerate after a hard stop.
Disc Brake Wear Indicators
Your Buick 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).

A LAUTION:
The brake wear warning sound means that
sooner or later your brakes won’t work well. Thal
could lead to an accident. When you hear the
brake wear warning sound, have your vehicle
serviced
NOTICE:
Continuing to drive with worn-out ‘-ake pat-
could result in costly brake repair
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
1000 miles (1600 km), so your
brakes will adjust properly.
Braking in Emergencies
At some time, nearly every driver gets into a situation
that requires hard braking.
If you have anti-lock, you can steer and brake at the
same time. However, if
you don’t have anti-lock, your
first reaction
-- to hit the brake pedal hard and hold it
down
-- may be the wrong thing to do. Your wheels can
stop rolling. 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.
ProCarManuals.com

That could be off the road, into the very thing you were
trying to avoid,
or into traffic.
If you don’t have anti-lock, 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.
In an emergency
you will probably want to “squeeze”
the brakes hard without locking the wheels. If you hear
or feel the wheels sliding, ease off the brake pedal. This
will help you retain steering control.
(If
you & have anti-lock, it’s different: see Index under
“Anti-lock Brake System.”) 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 r8 easonable 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 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
of 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.

ProCarManuals.com

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.
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 Buick 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 quickly without removing
either hand.
Rut 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
1 AC
ProCarManuals.com

experts recommend that you use your safety belts ana
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 1/4 turn until the
right front tire contacts the pavement edge. Then turn
your steering wheel to go straight down the roadway.
OFF ROAD RECOVERY /+-- &-A ..
/
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

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.
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.
Don’t overtake a slowly moving vehicle too rapidly.
Even though
the brake lights 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 Buick’s
three control system.s. In
the braking skid your wheels
aren’t rolling. In the steering or cornering skid,
too
much speed or steeri.ng 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
handied 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
148
ProCarManuals.com

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.
If you have the anti-lock braking system, remember: It
helps avoid only the braking skid. If you do not have
anti-lock, then in a braking skid (where the wheels are
no longer rolling), release enough pressure on the brakes
to get the wheels rolling again. This restores steering
control. Push the brake pedal down steadily when you have
to stop suddenly.
As long as the wheels are rolling,
you will have steering control. Steer the way you want
to go.
Driving at Night
Night driving is more dangerous than day driving. One
reason is that some drivers are likely
to be impaired --
by alcohol or drugs, with night vision problems, or by
fatigue.
