INoTIcE .
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 wilI still have
some power brake assist. But you will
use it when you brake. Once the
power assist is used up, it may take
Homgez ta stop and the brake pedal will
be harder to push.
Anti-L~ck Brakes (ABS)
Your Corvette has an advanced
electronic braking system that will help
prevent skidding.
This light on the instrument panel will
go on when you start your vehicle.
See the Index under Anti-Lock Brake
System Light.

Anfi-Lock Brakes (CONT.)
Here's haw 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. The computer separately
works
the brakesat each front wheel
and at the .rear wheels.
e 74
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 alid road
conditions.
You can steer around the obstacle while
braking hard.
As you brake, your computer keeps
receiving
updates on wheel speed ad
controls braking pressure accordingly.
CAUTION

Don't pump the brakes. Just hold the
brake pedal downand let anti-lock
work for you. You may feel the brake
pedal
vibrate, or you -may notice some
noise,
but thi.s is normal.
When the ABS is active, the ABS

Corvette ASR (Acceleration SIip
R.egulati0.n) System
Yo& vehicle has an ASR system that
limits wheel
spin. This is especially
useful in slippery road conditions. The
ASR system works at all speeds. It
limits
wheel spin by reducing englne
torque
by cLusing the throttle and
managing
sp'ark and .applyiag the rear
brakes. You may €&el the system

Steering Tips-Driving on Curves
(CONT.)
Speed limit signs near curves warm 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 hont wheels are
straight ahead.
Try
to adjust your speed so you can
Wive” 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.
When you drive into
a curve at night,
it’s harder to see the road ahead
of you
because it bends away
from the straight
beams
of your lights. This is one good
reason to drive slower.

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
€ram 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. It is better
to remove as much
speed as you can
from a possible
collision. Then steer around the
9
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. You
must then be prepared to steer back to
your original lane and then brake to a
controlled stop.
Depending on your speed, this can be
rather violent for an unprepared driver.
This is one of the reasons driving
experts recommend that you use your
safety belts and keep both hands
on the
steering wheel.
The fact that such emergency situations
are always possible is
a good reason to
practice defensive driving at
all times.

Skidding (CONT.)
(including engine braking by shifting to
a lower gear). Any sudden change 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
bralung skid.
Steer the way you want
the vehicle to
go.
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.
Drive defensively. Remember, this is
the most dangerous time.
Don’t drink and drive. (See the Index
under Drunken Dn’ving for mure on
this problem.)
Adjust your inside rearview mirror to
reduce
the glare from headlights
behind you.
Since you can’t see as well, you may
need
to slow down and keep more
space between you and other vehicles.
It’s hard to teil how fast the vehicle
ahead
is going just by looking at its
taillights.
speed roads. Your headlights can light
up only so much road ahead.
Slow down, especially on higher
In remote areas, watch for animals.
If you’re tired, pull off the road in a
safe place and rest.

Myht Vision
No one can see as well at night, as in the
daytime. But as
we get older -these
differences increase. A. 50-year-ald driver may require .at least twice as
much light to see the same thing at
night as a 20-year-old.
What you 80 in the daytime can also
&ct your night vision. For example, if
you spen-d-the day in bright sunshine
you
are wise to wear sunglasses. Your
eyes will have less trouble adjusting to
night.
But if you’re driving, don’t
wear
sunglasses at night. They may cut down
on glare from headlights, but they also
make
a lot of things invisible that
should
r.enmin visible-such as parked
cars, obstacles, pedestrians, or even
trains blocking railway
crossings.. You
may want to put on your sunglasses
after you have pulled into a brightly
lighted service or refreshment area.
Eyes shielded from that glare may
adjust more quickly to darkness back
on the road, But be sure to remove your
sunglasses before
you .leave the service
area.
You can be temporarily blinded by
approaching lights. It
can take a second
or
two, or even several seconds, for
your eyes to readjust to the dark. When
you are faced with severe glare (as from
a driver who doesn’t lower the high
beams,
or a vehicle with misaimed
headlights),
slow down a little. Avoid
-staring directly into the approaching
lights. If there is a line of opposing
traffic, make occasional glances
over the
line of headlights to make certain that
one
of the vehicles isn’t starting to
move into your lane. Once you .are past
the bright lights, give your eyes time
to
readjust before resuming speed.
High Beams
If the vehicle approaching-you has its
high beams on, signal by fliclcing yours
to high and then back to low beam. This
is the usual signal to lower the
headlight beams. zf.the other
driver still
doesn’t lower the
beams, resist the
ternaptation to. put
your high beams on.
This only makes two ha-blinded
drivers.
On a freeway, use your high beams only
in remote axeas where you won’t impair
approaching drivers.
In some p€aces,
like cities, using high beams is illegal.
When you follow another vehicle on a
freeway
or highway, use low beams.
True, most vehicles
now have day-night
mirrors that enable the driver to reduce
glare. But outside
mirrors are not of this
type and high beams
from behind can
bother the driver ahead.

Torque Lock
(AUTQMATIC TRANSMISSION)
If you are parking on a hill and you
don’t shift your transmissian into
P (Park) properly, the weight of the
vehicle may put
too much force on the
parking pawl in the transmission. You
may find it difficult to pull the shift
lever out of
P (Ihrlr). This is called
“torque
lock.” To prevent torqu’e lock,
always
be sure to shift into P (Park)
properly before you leave the driver’s
seat.
To find out how, see the Index
under Shifting Into P (Park).
When you are ready to drive, move the
shift lever out
of P (Park) before you
release the parking brake.
If torque lock does occur, you may need
to. have another vehicle push yours a
little uphill to take some of-the pressure
from the transmiss.ion, ‘so you can pull
the
shifi lever out of P (Park).

Winter Driving
Here are some tips for winter driving:
Have your Corvette in good shape for
winter.
Be sure your engine coolant
mix is correct.
Snow tires can help in loose snow,
but they may give you less traction on
ice than regular tires. If you do not
expect to be driving
in deep snow, but
may have
to travel over ice, you may
not want to switch to
snow tires at .all.
YOU may want to put winter
emergency supplies in your vehicle.
Include
an ice scraper, a small brush or
broom, a supply of windshield washer
fluid, a rag, some winter outer clothing,
a small shovel, a flashlight, .a red cloth,
and a couple of reflective warning
triangles. And, if-you will be driving
under severe conditions,
include a small
bag of sand, a piece of old carpet or a
couple of burlap bags to help provide
traction. Be sure you properly secure
these items in your vehicle.

If You're Caught in a Blizzard
If you are stopped by heavy snow, you
could be in
a serious situation. You
should probably stay with your vehicle
unless you
know for sure that you are
near help and you can hike through the
snow. Here are some things
to do to
summon help and keep yourself and
your passengers
safe:
Turn on your hazard flashers.
Tie a red cloth to your vehicle to alert
police that you've been stopped
by the
snow.
!OO
Put on extra clothing or wrap a
blanket around you. If you have no
blankets or extra clothing, make body
insulators
from newspapers, burlap
bags, rags, floor mats-anything you
can wrap around yourself or tuck
under
your clothing tu keep warm.
