seconds when you start your vehicle. If
the light stays on or comes on while
you’re driving, there may be a problem

designed to sense vehicle speed in the
first minute after the vehicle is started.
If the vehicle is not moved
in that first
minute, the system records a fault. The

Clean your tape player with a

Care of Your Compact Discs
Handle discs carefully. Store them in theil
original cases or other protective cases
and away from direct sunlight and dust.
U
the surface of a disc is soiled, dampen a
clean, soft cloth in a mild, neutral
detergent solution and clean it, wiping
from the center to
the edge.
Be sure never to touch the signal surface
when handling discs. Pick up discs by
grasping the outer edges or the edge of
the
hole and the outer edge.
Power Antenna Mast Care
Your power antenna will look its best and
work well if it’s cleaned from time to
time.
To clean the antenna mast:
1. Turn on the radio to raise the antenna.
2. Dampen a clean cloth with mineral
spirits or an equivalent solvent.
3. Wipe the cloth over the mast, removing any dirt.
4. Wipe the mast dry with a clean cloth.
5. Turn the radio off and on to make the
antenna go down and up.
If the antenna is still dirty, repeat the steps.

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.

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.

about to stop rolling, the computer will

could. The computer is programmed to
make the most of available tire and road
conditions. of

ASR system automatically comes on
whenever you start your vehicle. To limit
wheel spin, especially in slippery road
conditions, you should always leave the
system on. But you can turn the ASR
system off
if you ever need to. (You
should turn the system off if your vehicle
ever gets stuck
in sand, mud, ice or snow.
See “Rocking Your Vehicle” in the

To

spin when you press the button, the

You can turn the system back on at any
time by pressing the button again. The

Braking in Emergencies
Use your anti-lock braking system when
you need to. With anti-lock, you can steer
and brakG at the same time. In many
emergencies, steering can help you more
than even the very best braking.

Driving on Curves
It’s important to take curves at a
reasonable speed.
A lot
of the “driver lost control” accidents
mentioned
on the news happen on curves.

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.

Downloaded from www.Manualslib.com manuals search engine Your Driving and the Road
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.

Connect it to the positive

has one.
8. Now connect the black negative (-)
cable to the good battery’s negative

touch anything until the next step.
9. The other end of the negative cable
doesn’t go to the dead battery. It goes
to a heavy, unpainted metal part on
the engine of the vehicle with the
dead battery. Attach the cable at least
18 inches (45 cm) away from the
dead battery, but not near engine
parts that move. The electrical
connection is just as good there, but
the chance of sparks getting back to
the battery is much less.
10. Now start the vehicle with the good
battery and
run the engine for a
while.
11. Try to start the vehicle with the dead
battery. If it won’t start after a few
tries, it probably needs service.
