tires CHEVROLET CORVETTE 1994 4.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine Features and Controls
For LTPWS to work properly, you must
drive your Corvette faster than
25 mph
(40 km/h) and for more than
2 miles
(4 km). The system will not warn you
before
you begin to drive that a tire is flat.
When the “LOW/FLAT TIRE’ light
comes on, check
the tire pressure in all
four road tires as soon as you can. Adjust
the tire pressure as needed to those shown
on the Tire-Loading Information label on
the driver’s door. If the light stays on after
the tire pressure is adjusted, see your
dealer.
NOTICE:
Driving with a flat tire may damage
the tire,
the wheel or the tire pressure
sensor installed inside the tire on the
wheel rim. Using tire sealants may
also damage
the sensor.
If you have EMTs, see “Extended
Mobility Tires”
in the Index. The
LTPWS sensor is directly opposite
the valve stem on the tire. Take care when
servicing or having your tires serviced.
The sensors may not work properly if
damaged. To prevent damage to the
sensors, see the 1994 Corvette Service
Manual for correct tire mounting and
dismounting procedures.
The “LOWRLAT TIRE” light may come
on if your vehicle is close to another
vehicle that has LTPWS and has a tire
with low pressure.
LTPWS can
warn you about a low tire,
but it does not replace normal tire
maintenance. See “Tires” in the Index.

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. That’s especially true for brain,
spinal cord and heart injuries. That means
that if anyone who has been drinking
-
driver or passenger - is in a crash, the
chance
of being killed or permanently
disabled is higher than if that person had
not been drinking. And we’ve already
seen that the chance of a crash itself is
higher for drinking drivers.

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.
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
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
314 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.
Avoid needless heavy braking. Some
people drive in spurts
- heavy
acceleration followed by heavy braking
- rather than keeping pace with traffic.

Downloaded from www.Manualslib.com manuals search engine Your Driving and the Road
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. Unless
your
ASR system is on, adding the
sudden acceleration can demand too
much of those places. You can lose
control.
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.
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. 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.

If other cars are lined up to pass a
slow vehicle, wait your turn. But take
care that someone isn’t trying to pass
you as you pull out to pass the slow
vehicle. Remember to glance over
your shoulder and check the blind
spot.
Check your mirrors, glance over your
shoulder, and start your left lane
change signal before moving out of
the right lane to pass. When you are
far enough ahead
of the passed vehicle
to see its front
in your inside mirror,
activate your right lane change signal
and move back into the right lane.
(Remember that your right outside
mirror is convex. The vehicle you just
passed may seem to be farther away
from you than it really is.)
Try not to pass more than one vehicle
at a time on two-lane roads.
Reconsider before passing the next vehicle.
Don’t overtake a slowly moving
vehicle too rapidly. Even though the
brake lights are not flashing, it may be
slowing down or starting
to turn.
If you’re being passed, make it easy
for the following driver to get ahead
of you. Perhaps you can ease a little
to the right.

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.

Downloaded from www.Manualslib.com manuals search engine 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 braking system (ABS) helps avoid only the braking skid.

1 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.
0 Drive defensively.
0 Don’t drink and drive.
0 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.
Slow down, especially on higher
speed roads. Your headlights can light
up only
so much road ahead.
In remote areas, watch for animals.
If you’re tired, pull off the road in a
safe place and rest.
Night Vision
No one can see as well at night as in
the daytime. But as we get older these
differences increase.
A 50-year-old
driver may require at least twice as much
light to see the same thing at night as a
20-year-old.
What you do in the daytime can also
affect your night vision. For example, if
you spend 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.
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
131 ..

Downloaded from www.Manualslib.com manuals search engine Your Driving and the Road
vehicle with misaimed headlights), slow
down a little. Avoid staring directly into
the approaching lights.
Keep your windshield and all the glass
on your vehicle clean
- inside and out.
Glare at night is made much worse by dirt
on the glass. Even the inside of the glass
can build up a film caused by dust. Dirty
glass makes lights dazzle and flash more
than clean glass would, making the pupils
of your eyes contract repeatedly.
Remember that your headlights light up
far less of a roadway when you are in a
turn
or curve. Keep your eyes moving;
that way, it’s easier to pick out dimly
lighted objects. Just as your headlights
should be checked regularly for proper
aim,
so should your eyes be examined
regularly. Some drivers suffer from night
blindness
- the inability to see in dim
light
- and aren’t even aware of it.

Driving in the Rain
Rain and wet roads can mean driving
trouble. On a wet road you can’t stop,
accelerate or turn as well because your
tire-to-road traction isn’t as good as on
dry roads. And, if your tires don’t have
much tread left, you’ll get even less
traction. It’s always wise to go slower and
be cautious
if rain starts to fall while you
are driving. The surface may get wet
suddenly when your reflexes are tuned
for driving on dry pavement.
The heavier the rain, the harder it is to
see. Even if your windshield wiper blades
are in good shape, a heavy rain can make
it harder to see road signs and traffic
signals, pavement markings, the edge
of the road, and even people walking. It’s wise
to keep your wiping equipment
in good shape and keep your windshield washer tank filled. Replace your
windshield wiper inserts
when they show
signs of streaking or missing areas on the
Windshield, or when strips of rubber start
to separate from the inserts.

Downloaded from www.Manualslib.com manuals search engine Driving too fast through large water
puddles or even going through some car washes can cause problems, too. The
water may affect your brakes. Try to
avoid puddles.
But if you can’t, try to
slow down before you
hit them.
Hydroplaning
Hydroplaning is dangerous. So much
water can build up under your tires that
they can actually ride
on the water. This
can happen if the road is wet enough and
you’re going fast enough. When your
vehicle is hydroplaning, it has little or
no
contact with the road.
Hydroplaning doesn’t happen often. But it
can
if your tires haven’t much tread or if
the pressure in one or more is low. It can
happen if a lot of water is standing on the
road.
If you can see reflections from trees,
telephone poles, or other vehicles, and
raindrops “dimple” the water’s surface,
there could be hydroplaning.
Hydroplaning usually happens at higher
speeds. There just isn’t a hard and fast
rule about hydroplaning. The best advice
IS to slow down when it is raining.
Some Other Rainy Weather Tips
0 Turn on your low-beam headlights -
not just your parking lights - to help
make you more visible to others.
0 Besides slowing down, allow some
extra following distance. And be
especially careful when you pass
another vehicle. Allow yourself more
clear room ahead, and be prepared to
have your view restricted by road
spray.
Have good tires with proper tread
depth. (See “Tires” in the Index.)

Downloaded from www.Manualslib.com manuals search engine begin to check traffic. Try to determine
where you expect to blend with the flow.
Try to merge into the gap
at close to the
prevailing speed. Switch on your turn
signal, check your mirrors and glance
over your shoulder as often as necessary.
Try to blend smoothly with the traffic
flow.
Once you are on the freeway, adjust your
speed to the posted limit or to the
prevailing rate if it’s slower. Stay in the
right lane unless you want to pass.
Before changing lanes, check your
mirrors. Then use your turn signal. Just
before you leave the lane, glance quickly
over your shoulder to make sure there
isn’t another vehicle in your “blind” spot.
Once you are moving on the freeway,
make certain you allow a reasonable
following distance. Expect to move
slightly slower at night.
When you want to leave the freeway,
move to the proper lane well
in advance.
If you miss your exit do not, under any
circumstances, stop and back up. Drive on
to the next exit.
The exit ramp can be curved, sometimes
quite sharply. The exit speed is usually
posted. Reduce your speed according to your speedometer, not
to your sense of
motion. After driving for any distance at
higher speeds, you may tend to think you
are going slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well
rested. If you must start when you’re not
fresh
- such as after a day’s work -
don’t plan to ,make too many miles that
first part
of the journey. Wear comfortable
clothing and shoes you can easily drive
in.
Is your vehicle ready for a long trip? If
you keep it serviced and maintained, it’s
ready to go. If it needs service, have it
done before starting out. Of course, you’ll
find experienced and able service experts
in Chevrolet dealerships all across North
America. They’ll be ready and willing to
help if you need
it.
Here are some things you can check
before a trip:
Windshield Washer Fluid: Is the
reservoir full? Are all windows clean
inside and outside?
0 Wiper Blades: Are they in good
shape?
0
0
Fuel, Engine Oil, Other Fluids:
Have you checked all levels?
Lights: Are they all working? Are the
lenses clean?
Tires: They are vitally important to a
safe, trouble-free trip.
Is the wead
good enough for long-distance
driving? Are the tires all inflated to
the recommended pressure?
Weather Forecasts: What’s the
weather outlook along your route?
Should you delay your trip
a short
time to avoid a major storm system?
Maps: Do you have up-to-date maps?
Highway Hypnosis
Is there actually such a condition as
“highway hypnosis”? Or is it jugt plain
falling asleep at the wheel? Call it
highway hypnosis, lack of awareness, or
whatever.
There is something about an easy stretch
of road with the same scenery, along with
the hum of the tires on the road, the drone
of the engine, and the rush of the wind
against the vehicle that can make you
sleepy. Don’t let it happen to you! If it
does, your vehicle can leave the road in
less than a second, and you could crash
and be injured.

What can you do about highway
hypnosis? First, be aware that
it can
happen.
Then here are some tips:
0 Make sure your vehicle is well
ventilated, with a comfortably cool
interior.
0 Keep your eyes moving. Scan the road
ahead and to the sides. Check your
rearview mirrors and your instruments
frequently.
0 If you get sleepy, pull off the road into
a rest, service, or parking area and
take a nap, get some exercise, or both.
For safety, treat drowsiness on
the
highway as an emergency.
Hill and Mountain
Roads
Driving on steep hills or mountains is
jifferent from driving in flat or rolling
terrain. If you drive regularly in steep
zountry, or if you’re planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
Keep your vehicle in good shape.
Check all fluid levels and also the
brakes, tires, cooling system and
transmission. These parts can work
hard on mountain roads.
Know how to go down hills. The most
important thing to know is this: let
your engine do some
of the slowing
down. Shift to a lower gear when you
go down a steep or long hill.
0 Know how to go uphill. You may
want to shift down to a lower gear.
The lower gears help cool your engine and transmission, and you can climb
the hill better.

Driving on Snow or Ice
Most of the time, those places where you1
tires meet the road probably have good
traction.
However,
if there is snow or ice between
your iires 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 careful.
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°F; 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
ability to 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.
0
0
Allow greater following 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.
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. 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 to keep warm.
You can run the engine to keep warm, but
be careful.
