CHEVROLET CORVETTE 1997 5.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine Defensive Driving
The best advice anyone can give about driving is:
Drive defensively.
Please start with a very important safety device in your
Corvette: Buckle up. (See “Safety Belts” in the Index.) 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.
Drunken Driving
I 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:
0 Judgment
Muscular Coordination
0 Vision
0 Attentiveness.
Defensive driving really means “be ready for anything.”
On city streets, rural roads or freeways, it means
“always expect the unexpected.”

Downloaded from www.Manualslib.com manuals search engine 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 17,000 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 21, 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 The amount of alcohol consumed
0 The drinker’s body weight
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
180-lb. (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
(1 20 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.
4-3

Downloaded from www.Manualslib.com manuals search engine 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 United States
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 12 times greater; at a
level of 0.15 percent, the chance is
25 times greater!
4-4

Downloaded from www.Manualslib.com manuals search engine The body takes about an hour to rid itself of the alcohol
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.
Drinking and then driving is very dangerous.
Your reflexes, perceptions, attentiveness and
judgment can be affected by even a small amount
of alcohol. You can have a serious
-- or even
fatal
-- collision if you drive after drinking.
Please don’t drink and drive or ride with a driver
who
has been drinking. Ride home in a cab; or if
you’re with a group, designate
a driver who will
not drink.

Downloaded from www.Manualslib.com manuals search engine 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.
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 314 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; the condition of your brakes; the weight
of the
vehicle and the amount of brake force applied.
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.
4-6

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 vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
When you start your engine and begin to drive away,
your anti-lock brake system will check itself. You may
hear a momentary motor or clicking noise while this test
is going on, and you may even notice that your brake
pedal moves a little. This
is normal.
If there’s a problem with the
anti-lock brake system, this
warning light will stay on.
See “Anti-Lock Brake
4-7

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.
4-8

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 or always decrease
stopping distance. 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.
Using Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down
and let anti-lock work for you. You may hear a motor
or
clicking noise and feel the brake pedal move a little
during a stop, but this is normal.
When your anti-lock system is adjusting brake pressure
to help avoid a braking skid, the
ABS ACTIVE message
will come on. See “ABS ACTIVE Message” in
the Index.
Traction Control System (TCS)
Your vehicle has a traction control system called TCS
that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if it
senses that the rear wheels are spinning
too much or are
beginning to lose traction. When this happens, the
system works the rear brakes and reduces engine power
(by closing the throttle and managing engine spark) to
limit wheel spin.
The TRACTION SYSTEM ACTIVE message will
come on when the TCS system is limiting wheel spin.
See “TRACTION SYSTEM ACTIVE Message” in the
Index. You may feel or hear the system working, but this
is normal.
If your vehicle is in cruise control when the TCS system
begins to limit wheel spin, the cruise control will
automatically disengage. When road conditions allow
you to safely use
it again, you may re-engage the cruise
control. (See “Cruise Control”
in the Index.)
4-9

Downloaded from www.Manualslib.com manuals search engine TCS Light
The SERVICE TRACTION
SYSTEM message and the
TCS warning light will
come on to let you know if
there’s a problem with your TCS system. See
“SERVICE TRACTION
SYSTEM Message” in
the Index.
When this light and the SERVICE TRACTION
SYSTEM message are on, the system will not limit
wheel spin. Adjust your driving accordingly.
The TCS system automatically comes on whenever you
start your vehicle. To limit wheel spin, especially in
slippery road conditions, you should always leave the
system on. But you can turn the
TCS system off if you
ever need to. (You should turn the system off if your
vehicle ever gets stuck in sand, mud, ice or
snow. See
“Rocking
Your Vehicle” in the Index.) To
turn the system
off, press the button located on the
console. You can turn the system ON or
OFF at any time
by pressing the TCS switch. The DIC will display the
appropriate message when you push the button.

Downloaded from www.Manualslib.com manuals search engine Braking in Emergencies
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.
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.
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. Refer to
“Traction Control System” in the Index.
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.
