Control of a Vehicle
You have three systems that make your vehicle go where
you want it to go. They are the brakes, the steering and
the accelerator. All three systems have to do their work
at the places where the tires meet the road.
Sometimes, as when you’re driving on snow or ice, it’s
easy to ask more of those control systems than the tires
and road can provide. That means you can lose control
of your vehicle.
Braking
Braking action involves perception time and reaction
time.
First, you have to decide to push on the brake pedal.
That’s
perception time. Then you have to bring up your
foot and do it. That’s
reaction time.
Average reaction time is about 3/4 of a second. But
that’s only an average. It might be less with one driver
and as long as two or three seconds or more with
another. Age, physical condition, alertness, coordination,
and eyesight all play a part.
So do alcohol, drugs and
frustration. But even in 3/4 of a second, a vehicle
moving at
60 mph (100 km/h) travels 66 feet (20 m).
That could be a lot of distance in an emergency,
so
keeping enough space between your vehicle and others
is important.
And,
of course, actual stopping distances vary greatly
with the surface
of the road (whether it’s pavement or
gravel); the condition of the road (wet, dry, icy); tire
tread; and the condition
of your brakes.

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.

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

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 114 turn until the
right front tire contacts the pavement edge. Then turn
your steering wheel to go straight down the roadway.

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.
4-12
ProCarManuals.com

A cornering skid and an acceleration skid are 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 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 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 brake system
(ABS) helps
avoid
only the braking skid.
Driving at Night
Night driving is more dangerous than day driving. One
reason is that some drivers are likely to be impaired
-- by
alcohol
or drugs, with night vision problems, or by fatigue.
Here are some
tips on night driving.
0 Drive defensively.

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.

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 as
responsive as your vehicle is by
itself.
Before you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, 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 lamps 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.

ProCarManuals.com

When your vehicle is being towed, have the ignition key
off. The steering wheel should be clamped in a
straight-ahead position, with
a clamping device
designed for towing service.
Do not use the vehicle’s
steering column lock for this. The transaxle should be
in
NEUTRAL (N) and the parking brake released.
Don’t have your vehicle towed on the front wheels,
unless
you must. If the vehicle must be towed on the
front wheels, don’t go more than
35 mph (56 km/h) or
farther than
50 miles (80 km) or your transaxle will be
damaged.
If these limits must be exceeded, then the
front wheels have to be supported
on a dolly.
A CAUTION:

If a Tire Goes Flat
It’s unusual for a tire to “blow out” while you’re driving,
especially if you maintain your tires properly. If air goes
out
of a tire, it’s much more likely to leak out slowly.
But
if you should ever have a “blowout,” here are a few
tips about what
to expect and what to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip
the steering wheel firmly.
Steer to maintain lane position, then gently brake
to a
stop well
out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use
in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get
the vehicle under control by
steering the way
you want the vehicle to go. It may be
very bumpy and noisy, but
you can still steer. Gently
brake
to a stop, well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment to change
a flat tire safely.
