IS
Here you’ll find information about driving on different
kinds
of roads and in varying weather conditions. We’ve
also included many other useful tips on driving.
Defensive Driving
The best advice anyone can give about driving is: Drive
defensively.
Please start with
a very important safety device in your
Chevrolet: Buckle up. (See “Safety Belts”
in the Index.)
Defensive driving really means “be ready for anything.”
On city streets, rural roads, or freeways,
it means
“always expect the unexpected.”
Assume that pedestrians or other drivers are going to be
careless and make mistakes. Anticipate what they might
do. Be ready for their mistakes.
Rear-end collisions are about
the most preventable of
accidents. Yet they are common. Allow enough
following distance. It’s the best defensive driving
maneuver,
in both city and rural driving. You never
know when the vehicle
in front of you is going to brake
or
turn suddenly.

Death and injury associated
with drinking and driving is
a national tragedy. It’s the number one contributor to the
highway death toll, claiming thousands of victims every
year.
Alcohol affects four things that anyone needs
to drive a
vehicle:
Judgment
0 Muscular Coordination
0 Vision
0 Attentiveness
Police records show that almost half
of all motor
vehicle-related deaths involve alcohol. In most cases,
these deaths are the result of someone who
was drinking
and driving. In recent years, some 18,000 annual motor
vehicle-related deaths have been associated with the use
of alcohol, with more than
300,000 people injured.
Many adults
-- by some estimates, nearly half the adult
population
-- choose never to drink alcohol, so they
never drive after drinking.
For persons under 2 1, it’s
against the law in every
U.S. state to drink alcohol.
There are good medical, psychological and
developmental reasons for these laws. The obvious
way to solve this highway safety problem
is for people never
to drink alcohol and then drive. But
what if people do? How much is “too much” if the
driver plans to drive? It’s a lot less than many might
think. Although it depends on each person and situation, here is some general information on the problem.
The Blood Alcohol Concentration (BAC)
of someone
who is drinking depends upon four things:
0 How much alcohol consumed
0 The drinker’s body weight
0 The amount of food that is consumed before and
during drinking
The length of time it has taken the drinker to
consume the alcohol
According to the American Medical Association, a
1 80-pound (82 kg) person who drinks three 12-ounce
(355 ml) bottles of beer in an hour will end up with a
BAC
of about 0.06 percent. The person would reach the
same BAC by drinking three 4-ounce
(120 ml) glasses
of wine or three mixed drinks if each had
1-1/2 ounces
(45 ml) of a liquor like whiskey, gin or vodka.

It’s the amount of alcohol that counts. For example, if
the same person drank three double martinis (3 ounces
or
90 ml of liquor each) within an hour, the person’s
BAC would be close to
0.12 percent. A person who
consumes food just before or during drinking will have a
somewhat lower BAC level.
There is
a gender difference, too. Women generally have
a lower relative percentage of body water than men. Since
alcohol is carried in body water, this means that a
woman generally will reach a higher BAC level than a
man of her same body weight when each has the same
number
of drinks.
The law in many
U.S. states sets the legal limit at a BAC
of 0.10 percent. In a growing number of U.S. states, and
throughout Canada, the limit is
0.08 percent. In some
other countries
it’s even lower. The BAC limit for all
commercial drivers in the
U.S. is 0.04 percent.
The BAC will be over
0.10 percent after three to six
drinks
(in one hour). Of course, as we’ve seen, it
depends on how much alcohol is in the drinks, and how
quickly the person drinks them.
But the ability to drive is affected well below a BAC
of 0.10 percent. Research shows that the driving skills
of many people are impaired at a BAC approaching
0.05 percent, and that the effects are worse at night. All
drivers are impaired
at BAC levels above 0.05 percent.
Statistics show that the chance of being
in a collision
increases sharply for drivers who have
a BAC of
0.05 percent or above. A driver with a BAC level of
0.06 percent has doubled his or her chance of having a
collision. At a BAC level of 0.10 percent, the chance of
this driver having a collision is twelve times greater; at a
level of
0.15 percent, the chance is twenty-five times
greater

in one drink.
No amount of coffee or number of cold
showers will speed that up. “I’ll be careful” isn’t the
right answer. What
if there’s an emergency, a need to
take sudden action, as when a child darts into the street?
A person with even a moderate BAC might not be able
to react quickly enough to avoid the collision.
There’s something else about drinking and driving that
many people don’t know. Medical research shows that
alcohol in
a person’s system can make crash injuries
worse, especially injuries to the brain, spinal cord or
heart. This means that when anyone who
has been
drinking
-- driver or passenger -- is in a crash, that
person’s chance
of being killed or permanently disabled
is higher than if the person had not been drinking.

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.

Downloaded from www.Manualslib.com manuals search engine 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.
Anti-Lock Brakes (ABS)
Your Chevrolet has an advanced electronic braking
system that will help prevent a braking skid.
ANTI -
LOCI
This light
panel will
when you on the
instrument
come on briefly
start your vehicle.
When you start your vehicle,
or when you begin to drive
away, you may hear a momentary motor or clicking
noise. And you may even notice that your brake pedal
moves a little while this
is going on. This is the ABS
system testing itself.
If there’s a problem with the
anti-lock brake system, the anti-lock brake system
warning light will stay on or flash.
See “Anti-Lock Brake System Warning Light’’ in the
Index.

Downloaded from www.Manualslib.com manuals search engine 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.
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. 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.
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.

Downloaded from www.Manualslib.com manuals search engine 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
worhng, 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.
