On
very hot days, your vehicle will cool down more
quickly and economically if you open the windows long
enough to let hot inside
air escape. Then keep your
windows closed in order to allow the air conditioning to
work best. Maximum cooling will occur when the
RECIRCULATE setting is operating, airflow direction is
in the upper mode, and the temperature control knob (on
a manual climate control system) is turned all the way to
the blue area. These settings will be selected by the
Automatic Electronic Dual Climate Control System if
operating in AUTO when maximum cooling is required.
When the air conditioning is on, you may sometimes
notice slight changes in your vehicle’s engine
performance and power. This is normal. The system is
designed to .help fuel economy while maintaining the
desired cooling level.
The
air conditioning removes moisture from the air, so you
may notice water dripping fi-om under your vehicle when
it is idling or after it has been turned
off. This is normal. The
heater works best
if you keep your windows closed.
Maximum heating will occur when airflow direction is
in the lower mode and the temperature control knob (on
a manual climate control system) is all the way
in the
red area. These settings will be selected by the
Automatic Electronic Dual Climate Control System if
operating in AUTO when maximum heating is required.
The BI-LEVEL setting is designed for use on sunny days
when the
air is only moderately warm or cool. On days
like these, the sun may adequately warm your upper body,
but your lower body may not
be warm enough. The
BI-LEVEL setting will direct cooler airflow to
your upper
body and warmer
air to the floor area.
If you have the optional engine coolant heater and use it
during cold weather
0°F (- 18 “C) or lower, your heating
system will provide heat more quickly because the
coolant is already warmed. See “Engine Coolant Heater”
in the Index.

Downloaded from www.Manualslib.com manuals search engine 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
GM
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?
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked
all levels?
Lamps: Are they all working? Are the lenses clean?
Tires: They are vitally important to a safe,
trouble-free trip.
Is the tread 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?

Downloaded from www.Manualslib.com manuals search engine I A CAUTION:
Snow can trap exhaust gases under your vehicle.
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 a while.
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.

Two labels on your vehicle show how much weight it
may properly carry. The Tire-Loading Information label
found on the rear edge of the driver’s door tells you the
proper size, speed rating and recommended inflation. It
also gives you important information about the number
of people that can be in your vehicle and the total weight
that you can carry. This weight is called Vehicle
Capacity Weight and includes the weight
of all
occupants, cargo, and all non-factory-installed options.

The other label is the Certification label, found on the
rear edge of the driver’s door. It tells you the gross
weight capacity of your vehicle, called the GVWR
(Gross Vehicle Weight Rating). The GVWR includes the
weight of the vehicle, all occupants, fuel and cargo.
Never exceed the GVWR for your vehicle, or the
GAWR (Gross Axle Weight Rating) for either the front
or rear axle.
And, if you do have a heavy load,
you should spread it
out. Don’t carry more than
100 lbs. (45 kg) in your
rear area.

Downloaded from www.Manualslib.com manuals search engine CAUTION: (Continued)
Be sure you have sufficient knowledge,
-
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. “English” and “metric”
fasteners can be easily confused. If you use
the wrong fasteners, parts can later break
or fall off. You
could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you rnight add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your dealer before adding equipment to the outside
of
your vehicle.
Fuel
Use premium unleaded gasoline rated at 91 octane or
higher for best performance. You may use middle grade
or regular unleaded gasolines, but your vehicle may not
accelerate as well. At a
minimum, the gasoline you use should meet
specifications ASTM
D48 14 in the United States and
CGSB
3.5-M93 in Canada. Improved gasoline
specifications have been developed by the American
Automobile Manufacturers Association (AAMA) for
better vehicle performance and engine protection.
Gasolines meeting the AAMA specification could
provide improved driveability and emission control
system protection compared to other gasolines.
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 the recommended octane or
higher and you 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.
If your vehicle is certified to meet California Emission
Standards (indicated on the underhood emission control
label), it is designed to operate on fuels that meet
California specifications.
If such fuels are not available
in states adopting California emissions standards, your
f
6-3

Downloaded from www.Manualslib.com manuals search engine vehicle will operate satisfactorily on fuels meeting
federal specifications, but emission control system
performance may be affected. The malfunction indicator
lamp on your instrument panel may turn on and/or your
vehicle may fail a smog-check test. If
this occurs, return
to your authorized Corvette dealer for diagnosis to
determine the cause of failure. In the event it is
determined that the cause of the condition is the type of
fuels used, repairs may not be covered by your warranty.
Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT);
ask your service station operator whether or not
his fuel
contains MMT. General Motors does not recommend the
use of such gasolines.
If fuels containing MMT are used,
spark plug life may be reduced and your emission
control system performance may be affected. The
malfunction indicator lamp on your instrument panel
may turn on. If
this occurs, return to your authorized
Corvette dealer for service.
To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming
in your engine and fuel
system, allowing your emission control system to
function properly. Therefore, you should not have to add anything to the fuel. In addition, gasolines containing oxygenates, such as ethers and ethanol,
and
reformulated gasolines may be available in your area to
help clean the air. General Motors recommends that you
use these gasolines if they comply with the
specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. 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.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard to
find. Never use leaded gasoline or any other fuel not
recommended in the previous text on fuel. Costly repairs
caused by use of improper fuel 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.
