System Problems
If ,the light above a button flashes when
you turn on the ignition, your system may
have an electrical problem. The flashing
will continue for one minute, then stop.
The flashing light could also mean the
refrigerant level
is too low in your
system. The light will continue to flash, even
if refrigerant
is added, until the
system is reset. Have your system
checked and serviced
if needed.

Keep the hood and front air inlet free
of ice, snow, or any other obstruction
(such as leaves). The heater and
defroster will work far better, reducini
the chance of fogging the inside of
your windows.
When you enter a vehicle in cold
weather, adjust the fan to the highest
speed for a few moments before
driving
off. This helps clear the intake
ducts of snow and moisture, and
reduces the chance of fogging the
inside of your windows.
Keep the air path under the front seats
clear of objects. This helps air to
circulate throughout your vehicle.

Audio Systems
Your Delco@ audio system has been
designed to operate easily and give years
of listening pleasure. But you will get the
most enjoyment out of
it if you acquaint
yourself with it first. Find out what your
Delco@ system can do and how to operate
all its controls, to be sure you’re getting
the most out of the advanced engineering
that went into it.
NOTICE:
Before you add any sound equipment
to your
;chicle - like a tape player,
CB radio, mobile telephone or two-
way radio
- be sure you can add
what you want. If you can, it’s very
important to do it properly. Added
sound equipment may interfere
with the operation of your vehicle’s
engine, Delco@ radio or other systems, and even damage them. And, your
vehicle’s systems may interfere with
the operation of sound equipment
that has been added improperly.
So, before adding sound equipment,
check with your dealer and be sure to
check Federal rules covering mobile
radio and telephone units.

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 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.
. . .I32
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.

City Driving
One of the biggest problems with city
streets is the amount of traffic on them.
You’ll want to watch out for what the
other drivers are doing and pay attention
to trafflc signals.
Here are ways to increase your safety in
city driving:
0 Know the best way to get to where
you are going. Get a city map and
plan your trip into an unknown part
of the city just as you would-for a
cross-country trip.
Try to use the freeways that rim and
crisscross most large cities. You’ll
save time and energy. (See the next
section, “Freeway Driving.”)
. . .I34
Treat a green light as a warning signal.
A traffic light is there because the
corner is busy enough to need it.
When a light turns green, and just
before
you start to move, check both
ways for vehicles that have not
cleared the intersection or may be
running the red light.
Freeway Driving
Mile for mile, freeways (also called
thruways, parkways, expressways,
turnpikes, or superhighways) are the
safest of all roads.
But they have their
own special rules.
The most important advice on freeway driving is: Keep up with traffic and keep
to the right. Drive at the same speed most
of the other drivers are driving. Too-fast
or too-slow driving breaks
a smooth
traffic flow. Treat the left lane
on a
freeway as a passing lane.
At the entrance there is usually a ramp
that leads to the freeway. If you have a
clear view of the freeway as you drive
along the entrance ramp, you should

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.

If your battery has run down, you may
want to use another vehicle and some
jumper cables to start your Corvette.
But please follow the steps below to
do it safely.
NOTICE:
Ignoring these steps could result
in costly damage to your vehicle
that wouldn’t be covered by your
warranty.
Trying to start your Corvette by
pushing or pulling it could damage
your vehicle,
even if you have a
manual transmission. And if you
have an automatic transmission, it
won’t start that way.
Ib Jump Start Your Corvette:
1. Check the other vehicle. It must have
a 12-volt battery with a- negative
ground system.
NOTICE:
If the other system isn’t a 12-volt
system with a negative ground, both
vehicles can be damaged.
2. Get the vehicles close enough so the
jumper cables can reach, but be sure
the vehicles aren’t touching each
other. If they are, it could cause a ground connection you don’t
want.
You wouldn’t be able to start your
Corvette, and the bad grounding could
damage the electrical systems.
3. Turn off the ignition on both vehicles.
Turn
off all lights that aren’t needed,
and radios. This will avoid sparks and
help save both batteries. And it could
save your radio!
I NOTICE:
I
If you leave your radio on, it could be
badly damaged. The repairs wouldn’t
be covered by your warranty.
4. Open the hoods and locate the
batteries. Find the positive
(+) and
negative
(-) terminals on each.

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.
6. Positive (+) goes to positive (+) and
negative
(-) goes to negative (-) or a
metal engine part. Connect the red
positive
(+) cable to the positive (+)
terminal of the vehicle with the dead
battery. Use a remote positive
(+)
terminal if the vehicle has one.
