brakes BUICK SKYLARK 1993 User Guide

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.

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\

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

wet suddenly when your reflexes are tuned for driving
on dry pavement.
The heavier the rain, the harder it is to see. Even if your
windshield wiper bladesare in good shape, a heavy rain
can make it harder to see road signs and traffic signals,
pavement markings, the edge of the road, and even
people walking. Road spray can often be worse
for
vision than rain, especially if it comes from a dirty road.
So it is wise to keep your wiping equipment in good
shape and keep your windshield washer tank filled.
Replace your windshield wiper inserts when they
show
signs of streaking or missing areas on the windshield, or
when strips of rubber start to separate from the inserts.

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.

A CAUTION:
Wet brakes can cause accidents. The: ton’t

a quick stop and may cause pulling
to one side. You could lose control of the vehicle.
After driving through a large puddle of water or
car wash, apply your brake pedal ligh rtil
your brakes work normally.
Hydroplaning
Hydroplaning is dangerous. So much water can build up
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.
You might not be aware of hydroplaning. You could drive
along for some time without realizing your tires aren’t in
constant contact with the road. -You could find out the
hard way: when you have to slow, turn, move out to,pass
-- or if you get hit by a gust of wind. You could suddenly
fiid yourself out of control.
Hydroplaning doesn’t happen often. But it can if your
tires haven’t much tread or if the pressure in ?ne 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, and be
careful.
Some Other Rainy Weather Tips
0 Turn on your headlights -- not just your parang
lights
-- to help make you more visible to others.
0 Look for hard-to-see vehicles coming from behind.
You may want to use your headlights even in
daytime if it’s raining hard.
0 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.
If the road spray is so heavy you are
actually blinded, drop back. Don’t pass until
conditions improve. Going more slowly is better
than having an accident.
Use your defogger if it helps.
Have good tires with proper tread depth. (See “Tires” in the Index.)

Driving on steep hills or mountains is different from
driving in flat or rolling terrain. 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.
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.
Know how to go down hills. The most important
thing to know is this: let your engine do some of the
slowing down. Don’t make your brakes do it all.
Shift to a lower gear when you go down a steep or
long hill. That way, you will slow down without
excessive use of your brakes.

Towing a Trailer
A CAUTION:
If you don’t use the correct equipment and drive
properly, you can lose control when you pull
a
trailer. For example, if the trailer is too heavy. the
brakes may not work well
-- or even at all. Yo
and your passengers could be seriously injured.
Pull
a trailer only if you have followed all the
steps in this section.

the information in “Weight of the Trailer”. that appears

Load-pulling components such as the engine, transaxle, wheel assemblies, and tires are forced to work harder
against the drag of the added weight. The engine is

The bumpers on your vehicle are not intended for
hitches.
Do not attach rental hitches or other
bumper-type hitches to them.
Safety Chains
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 manufacturer’s recommendation for
attaching safety chains. Always leave just enough slack
so you can turn with your rig. And, never allow safety
chains to drag
on the ground.
Trailer Brakes
Does your trailer have its own brakes? 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. ff 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.
d
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.
nrn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have a
different turn signal flasher and extra wiring. The green
arrows on your instrument panel will flash whenever you signal a turn or lane change. Properly hooked up, the trailer lights will also flash, telling other drivers
you’re about to turn, change lanes or stop.
When towing a trailer, the green arrows on your
instrument panel will flash for turns even if the bulbs on
the trailer are burned out. Thus, you may think drivers
behind you are seeing your signal when they are not. It’s
important to check occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long
or steep downgrade. If you don’t shift
down, you might have to use your’brakes
so much that
they would get hot and no longer work well.
On a long uphill grade, use the highest gear. possible. If
you cannot maintain posted speeds, driving at a lower
speed may help avoid overheating your engine and
transaxle.
Parking on Hills
You really should not park your vehicle, with a trailer
attached, on a hill. If something goes wrong, your rig
could
start to move. People can be injured, and both
your vehicle and the trailer can be damaged.

Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill),
engine oil, belt, cooling system, and brake adjustment.
Each of these is covered in this manual, and the Index
will help you find them quickly.
If you’re trailering, it’s
a good idea to review these sections before
you start
your trip.
Check periodically to see that all hitch nuts and bolts are
tight.
I 1. Apply your regular brakes and hold the pedal down
while you:

0 Shift into a gear; and
0 Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
