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 colnputer 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.
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 feel the system
working, or
you may notice some noise, but this is
normal. When your anti-lock system is adjusting brake
pressure to help avoid a braking skid, the
LOW TRAC
light will come on. See “Anti-Lock Brake System
Active Light”
in the Index.
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.
ProCarManuals.com

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. 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.
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. (See “Braking
in
Emergencies” earlier in this section.) 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.
ProCarManuals.com

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 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.

Driving too fast through large water puddles or even
going through some car washes can cause problems, too.
The water may affect your brakes. Try to avoid puddles.
But if you can’t, try to slow down before you
hit them.
I . .. . .
Hydroplaning
Hydroplaning is dangerous. So much water can build LIP
under your tires that they can actually ride on the water.
This can happen
if the road is wet enough and you’re
going fast enough. When your vehicle
is hydroplaning,
it has
little or no contact with the road. Hydroplaning doesn’t happen often.
But it can if your
tires haven’t much tread or
if the pressure in one or
more is low. It can happen
if a lot of water is standing on
the road. If you can see reflections from trees, telephone
poles, or other vehicles, and raindrops “dimple” the
water’s surface, there could be hydroplaning.
Hydroplaning usually happens at higher speeds. There
just isn’t
a hard and fast rule about hydroplaning. The
best advice is to
slow down when it is raining.

Turn on your low-beam headlamps -- not just your
parking
lamps -- to help make you more visible to
others.
Besides slowing down, allow some extra following
distance. And be especially careful when you
pass
another vehicle. Allow yourself more clear room
ahead, and be prepared
to have your view restricted
by road spray.
Have good tires
with proper tread depth. (See
“Tires”
in the Index.)

If you drive regularly in steep country, or if you’re
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
0 Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system and
transaxle. These parts can work hard
on mountain
roads.
0 Know how to go down hills. The most important
thing to know is this: let your engine
do some of the
slowing down. Shift to a lower gear when you go
down a steep or long
hill.
A CAUTION:
If you don’t shift down, your brakes eould get so

Know how to go uphill. You may want to shift down
to
a lower gear. The lower gears help cool your engine
and transaxle, and
you can climb the hill better.
Stay
in your own lane when driving on two-lane
roads
in hills or mountains. Don’t swing wide or cut
across the center
of the road. Drive at speeds that let
you stay
in your own lane.
As you go over the top of a hill, be alert. There
could be something
in your lane, like a stalled car
or an accident.
You may see highway signs on mountains that warn
of
special problems. Examples are long grades, passing or
no-passing zones, a falling rocks area, or winding
roads. Be alert to these and take appropriate action.

Driving on Snow or Ice
Most of the time, those places where your tires meet the
road probably have good traction.
However,
if there is snow or ice between your tires and the
road, you can have a very slippery situation. You’ll have a
lot less traction or “grip” and will need to be very careful.
What’s
the worst time for this‘? “Wet ice.” Very cold
snow or ice can be slick and hard
to drive on. But wet
ice can be even more trouble because
it may offer the least traction
of all. You can
get “wet ice” when it’s
about freezing
(32” F; 0” C) and freezing rain begins to
fall. Try to avoid driving
on wet ice until salt and sand
crews can get there.
Whatever the condition
-- smooth ice, packed, blowing
or loose snow
-- drive with caution. Accelerate gently.
Try not to break the fragile traction.
If you accelerate
too fast, the drive wheels
will spin and polish the surface
under the tires even more.
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.

Hitches Safety Chains
It’s
important to have the correct hitch equipment.
Crosswinds, large trucks going by, and rough roads are a
few reasons why you’ll need the right hitch. Here are
some rules to follow:
0
0
Will you have to make any holes in the body of your
vehicle when you install
a trailer hitch? If you do,
then be sure to seal the holes later when you remove
the hitch.
If you don’t seal them, deadly carbon
monoxide (CO) from your exhaust can get
into your
vehicle (see “Carbon Monoxide”
in the Index). Dirt
and water can, too.
The bumpers on your vehicle are not intended for
hitches.
Do not attach rental hitches or other
bumper-type hitches to them. Use only
a
frame-mounted hitch that does not attach to the
bumper. You
should always attach chains between your vehicle
and your trailer. Cross the safety chains under the tongue
of the trailer
so that the tongue will not drop to the road
if
it becomes separated from the hitch. Instructions
about safety chains may be provided by the hitch
manufacturer or
by the trailer manufacturer. Follow the
manufxturer’s recommendation for attaching safety
chains and do not attach them to
the bumper. Always
leave just enough slack
so you can turn with your rig.
And, never allow safety chains
to drag on the ground.
Trailer Brakes
If your trailer weighs more than 1,000 pounds (450 kg)
loaded, then
it needs its own brakes -- and they must be
adequate. Be sure to read and follow the instructions for
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 your vehicle’s brake
system. If
you do, both brake systems won’t work well,
or at
all.
