ASR Active Light
When your ASR system is limiting wheel
spin, the “ASR ACTIVE’ light will come
on. Slippery road conditions may exist if
this light comes
on, so adjust your driving
accordingly. The light will stay on for a
few seconds after the ASR system stops
limiting wheel spin. The “ASR ACTIVE’
light also comes
on briefly, as a bulb
check, when the engine is started.
Low Tire Pressure Warning Light
(Option)
The LTPWS has a sensor on each road
wheel that transmits to a receiver
on the
instrument panel. The system operates on
a radio frequency subject to Federal
Communications Commission (FCC)
Rules.
This device complies with Part
15 of the
FCC Rules. Operation
is subject to the
following two conditions:
1. This device may not cause harmful
2. This device must accept any
interference,
and
interference received, including
interference that may cause undesired
operation.
Changes or modifications to this system
by other than an authorized service
facility could void authorization to use
this equipment.
LOWIFLAT
TIRE
..
The Low Tire Pressure Warning System
(LTPWS) monitors air pressure in each
road tire while you’re driving your
Corvette. The “LOW/FLAT TIRE” light
will come
on whenever tire pressure in
any road tire goes below
25 psi (175 kPa)
and it will stay
on until you turn off the
ignition. The light may come on if any
LTPWS parts aren’t working properly.

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.

Downloaded from www.Manualslib.com manuals search engine 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.
SERVICE
I
Anti-Lock 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.
When you start your vehicle and begin to
drive away, you may hear a momentary
motor or clicking noise. And you may
even notice that your brake pedal moves
,
little while this is going on. This is the
ABS system testing itself. If there’s a
problem with the anti-lock brake system,
the anti-lock brake system warning light
will stay on.
See “Anti-lock Brake System Warning
Light” in the Index. Here’s how anti-lock works. Let’s, say
the road
is wet. You’re driving safely.
Suddenly an animal jumps out in front

ABS. ..
A computer senses that wheels &g,
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. of

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.)

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.

pressure cap. At any time during this
procedure if coolant begins
to flow
out
of the filler neck, reinstall the
pressure cap. Be sure the arrows on
the cap line up like this.
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, 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 qff the road
if possible.
If a tire goes flat, the next section 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
damage by driving slowly to a level place.
Turn on your hazard warning flashers.

Downloaded from www.Manualslib.com manuals search engine Compact Spare Tire
Although the compact spare was fully
inflated when your vehicle was new, it
can lose air after a time. Check the
inflation pressure regularly. It should be
60 psi (420 kPa). After installing the
compact spare on your vehicle, you
should stop as soon as possible and make
sure your spare tire is correctly inflated.
The compact spare is made to perform
well at posted speed limits for distances
up to
3,000 miles (5 000 km), so you can
finish your trip and have your full-size
tire repaired or replaced where you want.
Of course, it’s best to replace your spare
with a full-size tire as soon as you can.
Your spare will last longer and be in
good shape in case you need it again.
-
NOTICE:
Don’t take your compact spare
through an automatic car wash with
guide rails. The compact spare can
get caught on the rails. That can
damage the tire and wheel, and
maybe other parts
of your vehicle.
Don’t use your compact spare on some
other vehicle.
And don’t
mix your compact spare or
wheel with other wheels
or tires. They
won’t
fit. Keep your spare and its wheel
together.
NOTICE:
Tire chains won’t fit your compact
spare. Using them will damage
your vehicle and destroy the chains
too. Don’t use tire chains on your
compact spare.
If You’re Stuck: In
Sand, Mud, Ice or
Snow
What you don’t want to do when your
vehicle is stuck is to spin your wheels.
The method known as “rocking” can help
you get out when you’re stuck, but .you
must use caution.

Downloaded from www.Manualslib.com manuals search engine Extended Mobility Tires (omoiv)
If your Corvette has optional Goodyear
Extended Mobility Tires (EMT’s), the tires will have “EMT” molded on the
sidewalls. These tires perform
so well
without any air that a Low Tire Pressure
Warning System (LTPWS)
is used to
alert you if a tire has lost pressure.
A
“LOWELAT TIRE” light will appear on
your Driver Information Center if a tire’s
inflation pressure is less than
25 psi
(1 70 kPa). If the “LOWELAT TIRE”
light comes on, check your tire pressures
as soon as you can. See “Low Tire
Pressure Warning System” in
the Index
for additional information.
If a tire goes flat, you won’t need to stop
on the side of the road to change the tire.
You can just keep on driving. The shorter
the distance you drive and the slower the
speed, the greater the chance that the tire
will not have to be replaced. If you drive on
a deflated EMT for distances
of
50 miles (80 km) or less and at speeds of
55 mph (90 km/h) or less, there is a good
chance that the tire can be repaired. The
tire can operate effectively with no air
pressure for up to
200 miles (320 km) at
speeds up to
55 mph (90 km/h), but the
tire would then have to be replaced. Also
remember: When a tire is filled with air, it
provides a cushion between the road and
the wheel. Because you do not have this
cushion when driving on a deflated tire,
try to avoid potholes that could damage
your wheel and require replacement of it.
Some road hazards can damage a tire
beyond repair. This damage could occur
before you’ve driven on the tire in a
deflated condition. Whenever a tire has
been damaged, or if you’ve driven any
distance on a deflated EMT, check with
a Goodyear EMT Service Center to
determine whether the tire can be
repaired or should be replaced. To
maintain your vehicle’s extended
mobility feature, all replacement tires
must be Extended Mobility Tires.
See the Goodyear Extended Mobility Tire
Owner’s Manual and Limited Warranty
supplied with your Corvette for additional
information.

Inflation - Tire Pressure
The Tire-Loading Information label which is on the driver’s door shows the correct
inflation pressures for your tires, when they’re cold. “Cold” means your vehicle has
been sitting for at least three hours or driven no more than a mile.
For competitive driving or high-speed driving (over
150 mph or 240 krn/h), make
sure your tires are inflated to
35 psi (240 kPa). When you end this type of driving,
reduce the “cold” inflation pressures (if necessary) to those listed
on the
Tire-Loading Information label.
NOTICE:
Don’t let anyone tell you that underinflation or overinflation is all right. It’s not.
If your tires don’t have enough air (underinflation) you can get:
0 Too much flexing
0 Too much heat
0 Tire overloading
0 Bad wear
0 Bad handling
Bad fuel economy.
If your tires have too much air (overinflation), you can get:
Unusual wear
Bad handling
0 Rough ride
Needless damage from road hazards.
When to Check: Check your tires
mce
a month or more. Don’t forget
your compact spare tire. It should be at
50 psi (420 Wa).
How to Check: Use a good quality
pocket-type gauge to check tire
pressure. Simply looking at the tires
will not tell you the pressure,
=specially if you have radial tires
-
which may look properly inflated even
if they’re underinflated.
Lf your tires have valve caps, be sure to
put them back on. They help prevent
leaks by keeping out dirt and moisture.
Tire Rotation
I’he tires on your Corvette are
lirectional, asymmetrical, and are
different sizes front to rear. Due to this,
your tires should not be rotated. Each
tire and wheel should be used only in
the position it is in.

Be careful with a hair dryer or heat
lamp. You could scorch the fabric.
Wipe with a clean cloth.
Using Solvent-Type Cleaner on Fabric
First, see if you have to use solvent-type
cleaner at all. Some spots and stains will
clean
off better with just water and mild
soap.
If you need to use a solvent:
0
0 Gently scrape excess soil from the
trim material with a clean, dull knife
or scraper. Use very little cleaner, light
pressure and clean cloths (preferably
cheesecloth). Cleaning should start at
the outside of the stain, “feathering”
toward the center. Keep changing to a
clean section of the cloth.
When you clean a stain from fabric,
immediately dry the area with an air
hose, hair dryer, or heat lamp to help
prevent a cleaning ring. (See the
previous NOTICE.)
Fabric Protection
Your Corvette has upholstery and carpet
that has been treated with Scotchgard”
Fabric Protector, a 3M product.
Scotchgard
” protects fabrics by repelling
oil and water, which are the carriers of
most stains. Even with this protection,
you still need to clean your upholstery
often to keep it looking new.
Further information on cleaning is
available by calling 1-800-433-3296
(in Minnesota, 1-800-642-6167).
Special Cleaning Problems
Greasy or oily stains:
Such as grease,
oil, butter, margarine, shoe polish, coffee
with cream, chewing gum, cosmetic
creams, vegetable oils, wax crayon, tar
and asphalt.
Carefully scrape
off excess stain.
Follow the solvent-type instructions
described earlier.
Shoe polish, wax crayon, tar and
asphalt will stain if left on a vehicle
seat fabric. They should be removed
as soon as possible. Be careful,
because the cleaner will dissolve them
and may cause them to spread.
