Storing a Flat Tire (ZR-1 Rear Tires)
A ZR-1 rear tire will not fit in the tray, so
you must put it on the floor of the rear
area. Put the flat tire
in the storage bag
provided. Place the tire on the rear area
floor.
Use the luggage straps to hold the tire in
place. Loosen the straps, then attach each
end of the longer strap to the rear cargo
hooks.
Attach the other strap to the hook behind
the console. righten
the straps by pulling
on the loose
ends.
When the tire is stored in the rear cargo
area, you can’t store a removable roof
panel. It will not
fit into the latches
properly.
Put the wheel wrench back in its place
under
the driver’s seat. Be sure to tighten
the wingnuts. Raise the
tire carrier tray to its upper
position and tighten the latch bolt until
it
is snug.

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.

NOTICE:
Spinning your wheels can destroy
parts of your vehicle as well as the
tires. If you spin the wheels too fast
while shifting your transmission
back and forth, you can destroy your
transmission.
. . .I70
Rocking your vehicle to get it out:
First, turn your steering wheel left and
ight. That will clear the area around your
front wheels. You should
turn your ASR
system
off. (See “ASR System” in the
[ndex.) Then shift back and forth between
“R’ (Reverse) and a forward gear (or with
9 manual transmission, between First or
Second gear and Reverse), spinning the
wheels as little as possible. Release the
accelerator pedal while you shift, and
press lightly on the accelerator pedal
when the transmission is in gear. If that
doesn’t get you out after a few tries, you
may need to be towed out.
If you do need
to be towed out, see “Towing Your
Vehicle” in the Index.

Doing Your Own Service Work
If you want to do some of your own
service work, you’ll want to get the
proper Chevrolet Service Manual. It tells
you much more about how to service
your Corvette than this manual can.
To
order the proper service manual, see
“Service Publications” in the Index.
Your vehicle has an air bag system.
Before attempting to do your own
service work, see “Servicing Your Air
Service
Your Chevrolet dealer knows your vehicle
best and wants you to be happy with it.
We hope you’ll go to your dealer for all
your service needs. You’ll get genuine
GM parts and GM-trained and supported
service people.
We hope you’ll want to keep your GM
vehicle all
GM. Genuine GM parts have
one of these marks. Bag-Equipped
Corvette” inthe Index.
You should keep a record with all parts
receipts and list the mileage and the date
of any service work you perform. See
“Maintenance Record” in the Index.
I NOTICE:

If you try to do your own service
work without knowing enough about
it, your vehicle could be damaged.

Downloaded from www.Manualslib.com manuals search engine Fuel
Use premium unleaded gasoline rated at
91 octane or higher. You may use middle
grade or regular unleaded gasolines, but
your vehicle may not accelerate as well.
The gasoline you use should meet
specifications ASTM D4814 in the
U.S.
and CGSB 3.5-92 in Canada. These fuels
should have the proper additives,
so you
should not have to add anything to the
fuel.
In the U.S. and Canada, it’s easy to be
sure you get the right kind of gasoline
(unleaded). You’ll see “UNLEADED’
right on the pump. And only unleaded
nozzles will fit into your vehicle’s filler
neck.
Be sure the posted octane for premium
is
at least 91 (at least 89 for middle grade
and 87 for regular). If the octane is less
than
87, you may get a heavy knocking
noise when you drive. If it’s bad enough,
it can damage your engine.
If you’re using fuel rated at 91 octane or
higher and you still hear heavy knocking,
your engine needs service. But don’t
worry if you hear a little pinging noise
when you’re accelerating or driving up a
hill. That’s normal and you don’t have to
buy a higher octane fuel to get rid of
pinging. It’s the heavy, constant knock
that means you have a problem.
What about gasoline with blending
materials that contain oxygen
(oxygenates), such as MTBE or alcohol?
MTBE is “methyl tertiary-butyl ether.’’
Fuel that is no more than 15% MTBE is
fine for your vehicle.
Ethanol is ethyl or grain alcohol.
Properly-blended fuel that is no more
than
10% ethanol is fine for your vehicle.
Methanol
is methyl or wood alcohol.
NOTICE:
Fuel that is more than 5% methanol
is bad for your vehicle. Don’t use it.
It can corrode metal parts
in your fuel
system and also damage plastic and
rubber parts. That damage wouldn’t
be covered under your warranty.
And even at
5% or less, there must
be “cosolvents” and corrosion
preventers in this fuel to help avoid
these problems.
Gasolines for Cleaner Air
Your use of gasoline with deposit control
additives will help prevent deposits from
forming in your engine and fuel system.
That helps keep your engine
in tune and
your emission control system working
properly. It’s good for your vehicle, and
you’ll be doing your part for cleaner air.
Many gasolines are now blended with
oxygenates. General Motors recommends
that you use gasolines with these blending
materials, such as MTBE and ethanol. By
doing
so, you can help clean the air,
especially in those parts of the country
that have high carbon monoxide levels.
In addition, some gasoline suppliers are
now producing reformulated gasolines.
These gasolines are specially designed to
reduce vehicle emissions. General Motors
recommends that you use reformulated
gasoline. By doing
so, you can help clean
the air, especially in those parts of the
country that have high ozone levels.
You should ask your service station
operators
if their gasolines contain deposit
control additives and oxygenates, and if
they have been reformulated to reduce
vehicle emissions.

Fuels in Foreign Countries
If you plan on driving in another country
outside the
U.S. or Canada, unleaded
fuel may be hard to find.
Do not use
leaded gasoline. If you use even one
tankful, your emission controls won’t
work well or at all. With continuous use,
spark plugs can get fouled, the exhaust
system can corrode, and your engine oil
can deteriorate quickly. Your vehicle’s
oxygen sensor will be damaged. All of
that means costly repairs that wouldn’t
be covered by your warranty.
To check on fuel availability, ask an auto
club, or contact a major oil company that
does business
in the country where you’ll
be driving.
You can also write us at the following
address for advice. Just tell
us where
you’re going and give your Vehicle
Identification Number (VIN).

Filling
Your Tank
The cap is under a hinged door on the rear
of your vehicle. While
refueling, place the cap in the
indent to the left of the filler neck.
To take
off the cap, turn it slowly to the
left (counterclockwise).

Downloaded from www.Manualslib.com manuals search engine Be careful not to spill gasoline. Clean
5asoline from painted suirfaces
as soon
1s possible. See “Cleaning the Outside
If Your Corvette’’ in the Index.
When you put the cap back on, turn it to
:he right until you hear at least three
:licks.
NOTICE:
If you need a new cap, be sure to
get the right type. Your dealer can
get one for you.
If you get the wrong
type, it may not fit or have proper
venting, and your fuel tank and
emissions system might be damaged.
