Anti-Lock Brakes (ABS)
Your Buick has an advanced electronic braking system
that will help prevent skidding.
ANT‘ LOCK (@)
ANTI
LOCK
This light on the instrument panel will go on when you
start your vehicle.
When you start your vehicle and begin to drive away, you
may hear a momentary motor or clicking noise. And you
may even notice that your brake pedal moves a little while
this is going
on. This is the ABS system testing itself. If
there’s a problem with the anti-lock brake system, the
anti-lock brake system warning light will stay on.
See “Anti-lock Brake System Warning Light”
in the
Index. 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.
167
ProCarManuals.com

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.
m
b 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.
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 hear a motor or
clicking noise during a hard stop, but this is normal.
Traction Control System (Option)
Your vehicle may have a traction control system that
limits wheel spin. This is especially useful in slippery
road conditions. The system operates only
if it senses
that one or both of the front wheels are spinning or
beginning to lose traction. When
this happens, the
system works the front brakes and reduces engine power
(by shutting off fuel injectors and managing spark) to
limit wheel spin.
You may feel the system working, or you may notice
some noise, but this
is normal. If your vehicle is in
cruise control when the traction control system begins to

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 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. Both control systems --
steering and acceleration -- have to do their work where
the tires meet the road. Unless
you have traction control
and
the system is on, 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.
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.
170
ProCarManuals.com

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.
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. 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. 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.

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 is best handled by easing your foot off”
the accelerator pedal.
If you have the traction control system, remember: It
helps avoid only the acceleration skid.
If you do not have traction control, or if the system is
off, then an acceleration skid is also 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 c’ause 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 braking system
(ABS) helps
avoid only the braking skid.

ProCarManuals.com

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.
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.
If You’re Caught in a Blizzard
If you are stopped by heavy snow, you could be in a
serious situation. You should probably stay with your
vehicle unless you know
for sure that you are near help
and
you can hike through the snow. Here are some
things to do to summon help and keep yourself and your
passengers safe: Turn on your hazard flashers. Tie a red
cloth
to your vehicle to alert police that you’ve been
stopped by
the snow. Put on extra clothing or wrap a

the trailer brakes so you’ll be able to install, adjust and
maintain them properly. Because you have anti-lock
brakes, do not try
to tap into you vehicle’s brake system.
If
you do, both brake systems won’t work well, or at all.
Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the
trailer. And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly
so
responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform,
safety chains, electrical connector, lights, tires and
mirror adjustment. If the trailer has electric brakes, start
your vehicle and trailer moving and then apply the
trailer brake controller by hand to be sure the brakes are
working. This lets you check your electrical connection
at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lights and any trailer brakes
are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as you
would when driving your vehicle without a trailer. This
can help you avoid situations that require heavy braking
and sudden turns.
Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal
longer, you’ll need
to go much farther beyond the
passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the
left, just move that hand
to the left.
To move the trailer to the right, move your
hand to the right. Always back up slowly and,
if
possible, have someone guide you.
Making Turns
When you’re turning with a trailer, make wider turns
than normal.
Do this so your trailer won’t strike soft
shoulders, curbs, road signs, trees, or other objects.
Avoid jerky or sudden maneuvers. Signal well in
advance.
