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.

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

limit wheel spin, the cruise control will automatically
disengage. When road conditions allow you to safely
use it again, you may re-engage the cruise control. (See
“Cruise Control” in the Index.) traction control system
off if you ever need to. (You
should turn the system off if your vehicle ever gets stuck
in sand, mud, ice or snow. See “Rocking Your Vehicle’’
in the Index.)
TRACTION
OFF
The “TRACTION OFF” warning light will come on
when you turn the traction control system off. When the
system
is on, this light will come on to let you know if
there’s a problem with your traction control system. See
“Traction Control System Warning Light” in
the Index.
When this warning light is
on, the system will not limit
wheel spin. Adjust your driving accordingly.
The traction control system automatically comes on
whenever you start your vehicle.
To limit wheel spin,
especially in slippery road conditions,
you should
always leave the system on. But you can turn the To
turn the system off,
press the “TRACTION
CONTROL” button
on the
instrument panel to the left
of the steering wheel.
The “TRACTION
OFF” warning light will come on and
stay on.
If the system is limiting wheel spin when you
press the button, the system won’t
turn off right away. It
will wait until there’s no longer
a current need to limit
wheel spin.
You can
turn the system back on at any time by pressing
the button again. The “TRACTION
OFF” warning light
should go off.

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.

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.

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:
0 “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.
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.

0 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.
0 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.
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 ov’er your shoulder and check
the blind spot.

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 man 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.
0 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 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 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.
