Downloaded from www.Manualslib.com manuals search engine 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
Corvette dealerships all across North America. They’ll
be ready and willing to help if you need it.

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?

Is there actually such a condition as “highway hypnosis”?
Or
is it just 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.

Make sure your vehicle is well ventilated, with a
comfortably cool interior.
Keep your eyes moving. Scan the road ahead and to
the sides. Check your rearview mirrors and your
instruments frequently.
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 different from
driving in flat or rolling terrain.

Downloaded from www.Manualslib.com manuals search engine If you drive regularly in steep country, or if you’re
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
0
0 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.
I
If you don’t shift down, your brakes could get so
hot that they wouldn’t work well. You would then
have poor braking or even none going down a hill.
You could crash. Shift down to let your engine
assist your brakes on a steep downhill slope.
’ A CAUTION:
I
Coasting downhill in NEUTRAL (N) or with the
ignition
off is dangerous. Your brakes will have to
do all the work of slowing down. They could get
so
hot that they wouldn’t work well. You would then
have poor braking or even none going down a
hill.
You could crash. Always have your engine running
and your vehicle
in gear when you go downhill.
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.
Stay in your own lane when driving on two-lane
roads in hills or mountains. Don’t swing wide or cut
across the center of the road. Drive at speeds that let
you stay in your own lane.

special problems. Examples are long grades, passing or
no-passing zones, a falling rocks area or windmg
roads. Be
alert to these and take appropriate action.

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.

Other Warning Devices
If you carry reflective triangles, you can set one up at the sid\

300 feet (100 m) behind your vehicle.
Jump Starting
If your battery has run down, you may want to use another
vehicle and some jumper cables to start your Corvette.
But please use the following steps to do it safely.
NOTICE:
Ignoring these steps could result in costly damage
to your vehicle that wouldn’t be covered by
your warranty.

need to add water to the Delco Freedom@ battery
installed in every new
GM vehicle. But if a battery
has filler caps, be sure the right amount of fluid
is
there. If it is low, add water to take care of that
first.
If you don’t, explosive gas could be present.
Battery fluid contains acid that can burn you.
Don’t get
it on you. If you accidentally get it in
your eyes
or on your skin, flush the place with
water and get medical help immediately.
5. Check that the jumper cables don’t have loose or
missing insulation. If they do,
you could get a shock.
The vehicles could be damaged, too.
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engines are running.
6. Positive (+) goes to positive (+) and negative (-)

Heater and radiator hoses, and other engine
parts, can be very
hot. Don’t touch them. If you
do, you can be bul‘ned.
Don’t run the engine
if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
I NOTICE:
I
Engine damage from running your engine
without coolant isn’t covered by your warranty.

If there seems to be no leak, with the engine on, check to
see if the electric engine fans are running.
If the engine
is overheating, both fans should be running. If they
aren’t, your vehicle needs service.

rear storage compartment behind the passenger’s seat.
Make sure the parts are stored properly in the foam
container. Position the jack in the container
so that you
can read the yellow CAUTION label fromthe driver’s
seat. Replace the plastic tray and close the storage
compartment.
NOTICE:
Your Corvette’s radio receiver box is in the rear
storage compartment.
To help avoid damage,
carefully place the jack, socket and wheel lock
key into the foam container in the compartment.
Do not toss or place the items against the radio
receiver box or any wiring.
Compact Spare Tire (If So Equipped)
Although the compact spare tire 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 Wa).
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 OOO 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.
When the compact spare is installed, your
vehicle’s handling capabilities will be reduced
during severe maneuvers.
If you drive too fast,
you could lose control
of your vehicle. You or
others could be injured. Don’t drive over
55 mph
(90 km/h) when the compact spare is installed.

If you have the 5.7L Code 5 engine, use premium
unleaded gasoline rated at
91 octane or higher.
If you have the 5.7L Code
P engine, 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 D4814 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 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.
If your vehicle
is certified to meet California Emission
Standards (indicated on the underhood tune-up 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 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.
