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. Avoid
needless heavy braking. Some people drive in
spurts
-- heavy acceleration followed by heavy braking
-- rather than keeping pace with traffic. This is a
mistake. Your brakes may
not have time to cool between
hard stops. Your brakes
will wear out much faster if you
do a lot of heavy braking. If you keep pace with the
traffic and allow realistic following distances, you will
eliminate a lot of unnecessary braking. That means
better braking and longer brake life.
If your engine ever stops while you’re driving, brake
normally but don’t pump your brakes. If you do, the
pedal may get harder to push down. If your engine
stops, you
will still have some power brake assist. But
you
will use it when you brake. Once the power assist is
used up,
it may take longer to stop and the brake pedal
will be harder to push.

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.
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.

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, 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 braking system (ABS) helps
avoid only the braking skid.

Tires: They are vitally important
to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?
Weather Forecasts: What’s

your route? Should you delay
your trip a short time
to avoid a major storm system?
Maps:
Do you have ur>-to-date maps?
Highway Hypnosis
Is there actually such a condition as “highway hypnosis”?
Or is
it just plain falling asleep at the wheel? Call it
highway hypnosis, lack of awareness, or whatever.
There is something about an easy stretch
of road with the
same scenery, along with the hum of the tires on the road,
the drone of the engine, and the rush of the wind against
the vehicle that can make you sleepy. Don’t let
it happen
to you! If
it does, your vehicle can leave the road in
than a second, and
you could crash and be injured.
What can you do about highway hypnosis? First, be
aware that
it can happen.

Make sure your vehicle is well ventilated, with a
comfortably cool interior.
Keep your eyes moving. Scan the road ahead and to
the sides. Check your rearview mirrors and your
instruments frequently.
If you get sleepy,
pull off the road into a rest, service,
or parking area and take a nap, get some exercise, or
both. For safety, treat drowsiness on the highway as
an emergency.

Hill and Mountain Roads
I
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.
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.

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.
Winter Driving
Here are some tips for winter driving:
0 Have your Buick in good shape for winter. Be sure
your engine coolant mix is correct.
0 You may want to put winter emergency supplies in
your trunk.

bags, rags, floor mats -- anything you can wrap around
yourself or tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That
is, push the accelerator slightly. This
uses less fuel for the heat that you get and
it keeps the
battery charged. You will need a well-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlights. Let the heater run for awhile.

Then, shut the engine off and close the window almost
all the way
to preserve the heat. Start the engine again
and repeat this only when you
feel really uncomfortable
from the cold. But do
it as little as possible. Preserve the
fuel as long as you can.
To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or
so until help comes.
Towing a Trailer
I NOTICE: I
Pulling a trailer improperly can damage your
vehicle and result in costly repairs not covered
by your warranty.
To pull a trailer correctly, follow
the advice in this section, and see your Buick
dealer for important information about towing a
trailer with your vehicle.
Your car can tow a trailer if it is equipped with 3.1L or
3.8L V6 engine and proper trailer towing equipment. To
identify what the vehicle trailering capacity is for your
vehicle, you should read the information
in “Weight of
the Trailer” that appears later in this section. But
trailering is different than just driving your vehicle by
itself. Trailering means changes in handling, durability,
and fuel economy. Successful, safe trailering takes
correct equipment, and it has to be used properly.
That’s the reason for this section. In it are many
time-tested, important trailering tips and safety rules.
Many of these are important for your safety and ‘that of
your passengers.
So please read this section carefullv
before
you pull a trailer.
