A CAUTION:
Driving without washer fluid can be
dangerous.
A bad mud splash can block
your vision. You could
hit another vehicle
or
go off the road. Check your washer
fluid level often.
In freezing weather, don’t use your washer
until the windshield is warmed. Otherwise
the washer fluid can form ice on the
windshield, blocking your vision.

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. 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.
155

I 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.
. 5 ’,.
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 the
anti-lock pump or motor operate, and feel the brake
pedal pulsate, but this is normal.
.
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).
I ‘
A CAUTION:
The brake wear warning sound means that
sooner or later your brakes won’t work well.
That could lead to an accident. When you hear
the brake wear warning sound, have your
:~
vehicle serviced. &tz
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.
156

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
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.
157

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 acceleratorpedal 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 enoughewater, 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. 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 --
