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

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 noid and feel the brake pedal move a little
during
a stop, but this is normal.
ABS
ACTIVE
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
this light will come on. See
“Anti-Lock Brake System
Active Light” in the Index.
ASR (Acceleration Slip Regulation) System
Your vehicle has a traction control system called ASR
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.
ASR
ACTIVE
This light will come on
when the ASR system is
limiting wheel spin. See
“ASR System Active Light”
in the Index. You may feel
or hear the system working,
but this is normal.
If your vehicle is in cruise control when the ASR 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.)

ASR
This warning light will
come on to let you know if
there’s a problem with your
ASR system. See “ASR
System Warning Light” in
the Index.
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly. (The ASR
OFF light will also come on when the ASR system
warning light comes on.)
The ASR system automatically comes on whenever you
start your vehicle.
To limit wheel spin, especially in
I slippery road conditions, you should always leave the
system on. But you can
turn the ASR 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
above-the
headlamp switch. The ASR
OFF light will come on and
stay on.
If the ASR system is limiting wheel spin when
you press the button,
the system will turn off right away.
You can turn the system back on at any time by pressing
the button again. The ASR
OFF light should go off.
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.

Downloaded from www.Manualslib.com manuals search engine Steering in Emergencies
There are times when steering can be more effective
than bralung. 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 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 Corvette’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 is best handled by easing your foot off
the accelerator pedal.
Remember: Any
ASR system helps avoid only the
acceleration skid. If
your
ASR system is off, then an acceleration skid
is also 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 brake system (ABS) helps
avoid only the braking skid.

Downloaded from www.Manualslib.com manuals search engine Driving on Snow or Ice
Most of the time, those places where your tires meet the
road probably have good traction.
However, if there is snow or ice between your tires and the
road, you can have a very slippery situation. You’ll have a
lot less traction or “grip” and will need to be very ca\
reful.
What’s the worst time for this? “Wet ice.” Very cold
snow or ice can be slick and hard to drive on. But wet
ice can be even more trouble because it may offer the
least traction of all. You
can get wet ice when it’s about freezing
(32 OF; OOC)
and freezing rain begins to fall. Try to avoid driving on
wet ice until salt and sand crews can get there.
Whatever the condition
-- smooth ice, packed, blowing
or loose snow
-- drive with caution.
Keep your ASR system on. It improves your ability to
accelerate when driving on a slippery road. Even though
your vehicle has the ASR system, you’ll want to slow
down and adjust your driving to the road conditions. See
“ASR System”
in the Index.
Your anti-lock brakes improve your vehicle’s stability
when you make a hard stop on a slippery road. Even
though you have the anti-lock braking system, you’ll
want to begin stopping sooner than you would on dry
pavement. See “Anti-Lock” in the Index.
Allow greater foliowing distance on any slippery road.
Watch for slippery spots. The road might be fine
until you hit a spot that’s covered with ice. On an
otherwise clear road, ice patches may appear in
shaded areas where the sun can’t reach: around
clumps of trees, behind buildings or under bridges.
Sometimes the surface of a curve or an overpass may
remain icy when the surrounding roads are clear. If
you see a patch
of ice ahead of you, brake before you
are on it. Try not to brake while you’re actually on
the ice, and avoid sudden steering maneuvers.

This can cause deadly
CO (carbon monoxide) gas
to get inside. CO could overcome you and kill
you. You can’t see it or smell
it, so you might not
know it
is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn’t collect there.
Open a window just
a little on the side of the
vehicle that’s away from the wind. This will help
keep
CO out.
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 headlamps. 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.

A vehicle
can fall from a car carrier if it isn’t
adequately secured. This can cause a collision,
serious personal injury and vehicle damage. The
vehicle should be tightly secured with chains or
steel cables before
it is transported.
Don’t use substitutes (ropes, leather straps,
canvas webbing, etc.) that can be cut by sharp
edges underneath the towed vehicle. Always use
T-hooks inserted in the T-hook slots. Never use
J-hooks. They will damage drivetrain and
suspension components.
When your vehicle is being towed, have the ignition
key

H
I NOTICE:
Your engine has a specific coolant high fill
reservoir
fill procedure. Failure to follow this
procedure could cause your engine
to overheat
and be severely damaged.
1. You can remove the coolant high fill reservoir
pressure cap when the cooling system, including the
coolant high
fill reservoir pressure cap and upper
radiator hose, is no longer hot. Turn the pressure cap
slowly counterclockwise
until it first stops. (Don’t
press down while turning
the pressure cap.)
If you hear a hiss, wait for that to stop. A hiss means
there is still some pressure left.
2. Then keep turning the pressure cap, but now push
down
as you turn it. Remove the pressure cap.

Downloaded from www.Manualslib.com manuals search engine If a Tire Goes Flat
It’s unusual for a tire to “blow out’’ while you’re driving,
especially if you maintain your tires properly. If air goes
out of a tire, it’s much more likely to leak out slowly.
But if you should ever have a “blowout,” here are a few
tips about what to expect and what to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot
off
the accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake
to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get
the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop
-- well off the road if possible.
If
a tire goes flat, the next part shows how to use your
jacking equipment to change a flat tire safely. If your
vehicle has Extended Mobility Tires (tires with
“EMT”
molded on the sidewalls), see “Extended Mobility Tires”
in the Index.
.Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your hazard
warning flashers.
A CAUTION:
3
Changing a tire can cause an injury. The vehicle
can slip off the jack and roll over you or other
people. You and they could be badly injured.
Find
a level place to change your tire. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put an automatic transmission shift lever in
PARK (P), or shift a manual transmission
to
FIRST (1) or REVERSE (R).
3. lbrn off the engine.
To
be even more certain the vehicle won’t move,
you can put blocks at the front and rear of the
tire farthest away from the one being changed.
That would be the tire on the other side of the
vehicle, at the opposite end.
