To Play the Radio
Turn the upper knob to turn the system
on or
off.
~ Volume: Turn the upper knob to adjust
~ the volume. Your system also has a
’ feature called speed-compensated
volume (SCV). With SCV, your audio
system makes up for road noise by
getting louder as you drive faster. The
control behind the upper knob has three
SCV positions.
“H” has a higher
maximum volume and gets louder
faster than
“L.” Use “H” when you
are driving with the roof panel
off,
the convertible top down or the
windows open. If you don’t want to
use SCV,
turn the control to “OFF.”
Recall: Press the upper knob to recall the
station being played or the clock display.
Finding a Station

Fade: Turn the “FADE” knob to move
the sound between the front and rear
speakers. Note that if you turn the knob
all the way to
“F” or “R,” you may still
get some sound from the opposite
speakers.
To Play a Cassette Tape
Your tape player is built to work best with
tapes that are
30 to 45 minutes long on
each side. Tapes longer than that are
so
thin they may not work well in this player.
The longer side with the tape visible goes
in first.
If you hear nothing or hear just a
garbled sound, it may not be in squarely.
Press “EJCT” to remove the tape and
start over.
Once the tape is playing, use the knobs
for volume and fade, just as you do for
radio. If both a tape and a compact disc
are loaded into
the system, press
“CNCD’ to select
the one you want.
Reverse: Press “REV” to return to a
favorite passage rapidly. Press it again to
play the passage. The radio will play
while the tape is rewinding.
Fast Forward: Press “FF” to advance
the tape rapidly. Press it again to play.
The radio will play while the tape is
advancing.

Repeat: Press “REPT” to go to the
beginning of
the current selection after
ten seconds or more of play. After five
seconds or less of play,
the player will
return to
the beginning of the previous
selection.
Search: Press “SRCH’ to go to the
beginning of the next selection.
Scan: Press “SCAN’ to listen to the first
eight seconds of each passage. Press it
again to stop scanning.
Program: Press the upper knob to change
the side of the tape that is playing. The
lighted arrows show which side is
currently playing.
Eject: Press “EJCT” to remove the tape.
Stop: Press “STOP-PLAY” to listen to the
radio without ejecting the cassette tape.
Press it again to go back to the tape.
Metal Tapes: Press “CrO;! ” when
playing high bias chrome or metal tapes.
To Play a Compact Disc
Don’t use the mini-discs (3” singles).
They will eject, but they won’t play. Use
only full-size compact discs. With
the audio system
on, insert a disc
into
the slot with the label side up. “CD”
will appear on the display and track
1 will
begin to play. If both
a tape and a
compact disc are loaded into the system,
press “CNCD’ to select the one you
want.
If the disc comes back out and “ERR”
appears on the display, it could be that:
The disc is upside down.
It is dirty, scratched, or wet.
0 There’s too much moisture in the air.
(Wait about an hour and try again.)
You are driving on a very rough road.
The temperature is too hot or too cold.
Recall: Press “RCL“’ to see what track is
playing. Press it again within five seconds
to see how long it has been playing, the
elapsed time (“EL TIME’).
Reverse: Press and hold “REV” to return
to a favorite passage rapidly. The
decreasing elapsed time will show on
the
display.
Fast Forward: Press and hold “FF” to
advance through passages. The increasing
elapsed time will show on the display.

Press “EJCT” to eject the disc and
switch to radio. If the ignition or audio
system is turned
off, the player will
pull the disc back in if you don’t
remove it from the opening within
30 seconds.
Understanding Radio Reception
FM Stereo
FM stereo will give you the best sound.
But FM signals will reach only about
10 to 40 miles (16 to 65 km). And, tall
buildings or hills can interfere with
FM signals, causing the sound to come
and go.
AM
The range for most AM stations is greater
than for
FM, especially at night. The
longer range, however, can cause stations
to interfere with each other. AM can pick
up noise from things like storms and
power lines. Try reducing the treble to
reduce this noise if you ever get it. Care of Your Cassette Tape
Player
A tape player that is not cleaned regularly
can cause reduced sound quality, ruined
cassettes, or a damaged mechanism.
Cassette tapes should be stored in their
cases away from contaminants, direct
sunlight, and extreme heat. If they aren’t,
they may not operate properly or cause
failure of the tape player.
Your tape player should be cleaned
regularly each month or after every 15
hours of use. If
you notice a reduction in
sound quality, try a known good cassette
to see if the tape or the tape player
is
at fault. If this other cassette has no
improvement in sound quality, clean the
tape player.

Downloaded from www.Manualslib.com manuals search engine Comfort Controls and Audio Systems
Clean your tape player with a
wiping-action, non-abrasive cleaning
cassette
(GM Part No. 12344600), and
follow the directions provided with
it.
Cassettes are subject to wear and the
sound quality may degrade over time.
Always make sure that the cassette tape is
in good condition before you have your
tape player serviced.
. . .I18
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 According to the American Medical
Association, a 180-pound (82 kg) person
who drinks three 12-ounce (355 ml)
bottles
of beer in an hour will end up with
a BAC of about
0.06 percent. The person
would reach the same BAC by drinking
three 4-ounce (1 20
ml) glasses of wine or
three mixed drinks if each had 1
- 1/2
ounces (45 ml) of a liquor like whiskey,
gin or vodka.
It’s the amount of alcohol that counts. For
example, if
the same person drank three
double martinis (3 ounces or
90 ml of
liquor each) within
an hour, the person’s
BAC would be close to 0.12 percent. A
person who consumes food just before or
during drinking will have
a slightly lower
BAC level.

The law in most U.S. states sets the legal
limit at a BAC of 0.10 percent.
In Canada
the limit is
0.08 percent, and in some
other countries it’s lower than that. The
BAC will be over
0.10 percent after three
to six drinks (in one hour). Of course, as
we’ve seen, it depends on how much
alcohol is in the drinks, and how quickly
the person drinks them.
.,. c. .-’ .t
But it’s very important to keep in mind
that the ability to drive is affected well
below a BAC of 0.10 percent. Research
shows that the driving skills
of many
people ai-e impaired at a BAC
approaching
0.05 percent, and that the
effects are worse at night. All drivers are
impaired at BAC levels above
0.05
percent. Statistics show that the chance of
being in an accident increases sharply for
drivers who have a BAC of
0.05 percent
or above. A driver with a BAC level of
0.06 percent (three beers in one hour for a
180-pound or 82 kg person) has doubled
his or her chance of having an accident.
At a BAC level of 0.10 percent, the
chance of that driver having an accident is
six times greater; at a level of
0.15.
percent, the chances are twenty-five times
greater! And, the body takes about an
hour to rid itself
of the alcohol in :one
drink.
No amount of coffee or number of
cold showers will speed that
up.
“I’ll be careful” isn’t the right answer.
What if there’s
an emergency, a need to
take sudden action, as when a child darts
into the street? A person with a higher
BAC might not be able to react quickly
enough to avoid the collision.

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

wheel and at the rear wheels.

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

You can steer around the obstacle while
braking hard.
As you brake, your computer keeps
receiving updates on wheel speed and
controls braking pressure accordingly.
Remember: Anti-lock doesn’t change the
time you need to get your foot up to the
brake pedal.
If you get too close to the
vehicle
in front of you, you won’t have
time to apply your brakes if that vehicle
suddenly slows or stops. Always leave
enough room up ahead to stop, even
though you have anti-lock brakes.
To Use Anti-Lock
Don’t pump the brakes. Just hold the
brake pedal down and let anti-lock work
for you. You may hear a motor or clicking

noise and feel the brake pedal move a
little during a hard stop, but this is
normal. When your anti-lock system is
adjusting brake pressure to help avoid a
braking skid, the “ABS ACTIVE” light
will come on. See “Anti-Lock Brake
System Active Light” in the Index.
ASR (Accelerated Slip Regulation)
System
Your vehicle has an ASR system that
limits wheel spin. This is especially
useful in slippery road conditions. The
system operates only if it senses that the
rear wheels are spinning too much or
are beginning to lose traction. When this
happens, the system works
the rear brakes
and reduces engine power (by closing the
throttle and managing spark) to limit
wheel spin.
The “ASR ACTIVE” light will come on
when the ASR system is limiting wheel
spin. See “ASR Active Light”
in the
Index. You may feel the system working,
or you may notice some noise, but this is
normal.
If your vehicle is in cruise control when
the ASR system begins to limit wheel
spin, the cruise control will automatically disengage. When road conditions allow
you to safely use it again, you may
re-engage cruise control. (See “Cruise
Control” in the Index.)

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
Index.)
To
turn the system off, press the button
located above the headlight switch. The
“ASR

on. If the ASR system is limiting wheel
spin when you press the button, the
system won’t turn off right away. It will

need
to limit wheel spin.
You can turn the system back on at any
time by pressing the button again. The
“ASR

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.

Downloaded from www.Manualslib.com manuals search engine Off-Road Recovery
You may find sometime that your right
wheels have dropped off the edge of a
road onto the shoulder (A) while you’re
driving.
If the level of the shoulder is only slight11
below the pavement, recovery should be
fairly easy. Ease off the accelerator and
then,
if there is nothing in the way, steer
so that your vehicle straddles the edge of
the pavement.
You can turn the steering
wheel up to
1/4 turn (B) until the right
front tire contacts the pavement edge.
Then turn your steering wheel to
go
straight down the roadway.
Passing
fhe driver of a vehicle about to pass
mother on a two-lane highway waits for
ust the right moment, accelerates, moves
tround the vehicle ahead, then goes back
.nto the right lane again.
A simple
naneuver?
Vot necessarily! Passing another vehicle
In a two-lane highway is a potentially
langerous move, since the passing
fehicle occupies the same lane as
Incoming traffic for several seconds. A
niscalculation, an error in judgment, or
brief surrender to frustration or anger
:an suddenly put the passing driver face
:o face with the worst of all traffic
lccidents
- the head-on collision.
So here are some tips for passing:
“Drive ahead.” Look down the road,
to the sides, and
to crossroads for
situations that might affect your
passing patterns. If you have any
doubt whatsoever about making a
successful pass, wait for a better time.
Watch for traffic signs, pavement
markings, and lines. If you can see a
sign up ahead that might indicate a
turn or an intersection, delay your
pass. A broken center line usually indicates
it’s all right to pass
(providing the road ahead
is clear).
Never cross a solid line on your side
of the lane or a double solid line, even
if the road seems empty of
approaching traffic.
Do not get too close to the vehicle you
want to pass while you’re awaiting an
opportunity. For one thing, following
too closely reduces your area of
vision, especially if you’re following
a larger vehicle. Also, you won’t have
adequate space if the vehicle ahead
suddenly slows or stops. Keep back a
reasonable distance.
When it looks like a chance to pass
is coming up, start to accelerate but
stay in the right lane and don’t get too
close. Time your move
so you will be
increasing speed as the time comes to
move into the other lane. If the way is
clear to pass, you will have a “running
start” that more than makes up for the
distance you would lose by dropping
back. And if something happens to
cause you to cancel your pass, you
need only slow down and drop back
again and wait for another
opportunity.

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.
