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.

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

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 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.)

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.

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.
4-11

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

Downloaded from www.Manualslib.com manuals search engine 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.
I OFF-ROAD RECOVERY / A&*$
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 one-quarter turn until the
right front tire contacts the pavement edge. Then
turn your
steering wheel to go straight down the roadway.
Passing
The driver of a vehicle about to pass another on a
two-lane highway waits for just the right moment,
accelerates, moves around the vehicle ahead, then goes
back into the right lane again.
A simple maneuver?
Not necessarily! Passing another vehicle
on a two-lane
highway is a potentially dangerous move, since the
passing vehicle occupies the same lane as oncoming
traffic for several seconds,
A miscalculation, an error in
judgment, or a brief surrender to frustration or anger can
suddenly put the passing driver face to face with the
worst of all traffic accidents
-- the head-on collision.
So here are some tips for passing:
a “Drive ahead.” Look down the road, to the sides and to
crossroads for situations that might affect your passing
patterns.
If you have any doubt whatsoever about
making a successful pass, wait for a better time.
a Watch for traffic signs, pavement markings and lines.
If you can see a sign up ahead that might indicate a
turn or an intersection, delay your pass. A broken
center line usually indicates it’s all right
to pass
(providing the road ahead is clear). Never cross a solid
line
on your side of the lane or a double solid line,
even if the road seems empty
of approaching traffic.
