Cruise Control (Option) When you apply your brakes, the Cruise Control shuts
off.
A CAUTION:
0 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.
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 m).
I Cruise Control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause n dless
wheel spinning, and you could lose
control. Don’t use Cruise Control on
slippery roads.

A computer senses that wheels are slowing down. The
computer separately works the brakes at each fmnt
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.
__
r
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
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 also may hear a
clicking noise as you accelerate after a hard stop.
Disc Brake Wear Indicators
Your Buick 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).

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 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.
154

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
Qf 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. 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.

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. 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.

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 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’l\
l
..
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
I

start bralung. If you must brake on the through lane, and
if there
is traffic close behind you, you can allow a little
extra time and flash your brake lights (in addition to your turn signal) as extra warning that you are about to
slow down and exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted. Reduce your speed
according to your speedometer, not to your sense of
motion. After driving for any distance at higher speeds,
you may tend to think you are going slower than you
actually are. For example,
40 mph (65 km/h) might
seem like only
20 mph (30 km/h). Obviously, this could
lead to serious trouble on a ramp designed for
20 mph
(30 krn/h)!
Driving a Long Distance
Although most long trips today are made on freeways,
there are still many made on regular highways.
Long-distance driving on freeways and regular
highways is the same in some ways. The trip has to be
planned and the vehicle prepared, you drive at
higher-than-city speeds, and there are longer turns
behind the wheel. You’ll enjoy your trip more if you and
your vehicle are
in good shape. Here are some tips for a
successful long trip.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re not fresh
-- such as after a day’s
work
-- don’t plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it’s ready to go. If it needs
service, have it done before starting out. Of course,
you’ll find experienced and able service experts in
Buick dealerships all across North America. They’ll be
ready and willing to help
if you need it.
Here are some things you can check before a trip:
0 Windshield Washer Fluid: Is the reservoir full? Are
all windows clean inside and outside?
WiDer Blades: Are they in good shape/
Fuel, Engine Oil, Other Fluids: Have you checked
all levels?
0 Lights: Are they all working? Are the lenses clean?
0 Tires: They are vitally important to a safe,
trouble-free trip. Is the tread good enough for long-distance driving?
Are the tires all inflated to the
recommended pressure?

Weather Forecasts: What’s the weather outlook
along your route? Should you delay your trip a short
time to avoid a major storm system?
Maps: Do you have up-to-date maps?
On the Road
Unless you are the only driver, it is good to share the
driving task with others. Limit turns behind the wheel to
about
100 miles (160 km) or two hours at a sitting.
Then, either change drivers or stop for some refreshment
like coffee, tea or soft drinks and some limbering up.
But do stop and move around. Eat lightly along the way.
Heavier meals tend to make some people sleepy.
On two-lane highways or undivided multilane highways
that do not have controlled access;you’ll want to watch
for some situations not usually found on freeways.
Examples are: stop signs and signals, shopping centers with direct access to the highway, no passing zones and
school zones, vehicles turning left and right
off the road,
pedestrians, cyclists, parked vehicles, and even animals.
Highway Hypnosis
Is there actually such a condition as “highway hypnosis”?
Or is it just plain falling asleep at the wheel? Call it
highway hypnosis, lack of awareness, or whatever.
I
There is something about an easy stretch of road with the
same scenery, along with the hum of the tires on the road,
the drone of the engine, and the rush of the wind against
the vehicle that can make you sleepy. Don’t let it happen
to you!
If it does, your vehicle can leave the road in
than a second, and you could crash and be injured.
What can you do about highway hypnosis? First, be
aware that it can happen.

Make sure your vehicle is well ventilated, with a
comfortably cool interior.
Keep your eyes moving. Scan the road ahead and
to
the sides. Check your rearview mirrors frequently and your instruments from time to time.
This can help you
avoid a fixed stare.
Wear good sunglasses in bright light. Glare can cause
drowsiness. But don’t wear sunglasses at night. They will drastically reduce your overall vision at the very
time you need all the seeing power you have.
If you get sleepy, pull
off the road into a rest, service,
or parking area and take a nap, get some exercise, or
both. For safety, treat drowsiness on the highway as
an emergency.
As in any driving situation, keep pace with traffic and
allow adequate following distances.
