AmSt
The AmSt button is just below the PWR button. Push this when you tune to
an AM station that broadcasts
in stereo. Your STEREO light will come on
when you’re receiving AM stereo.
If you push AmSt and there is no more
noise, it means the station is weak. You’ll hear the station better
if you don’t
use
AmSt. Just push the AmSt button again to cancel stereo.
NOTE: Your Delco system may be able to receive C-QUAM@ stereo
broadcasts. Many AM stations around the country use
C-QUAM@ to produce
stereo, though some
do not. C-QUAM@ is a registered trademark of Motorola
Inc.
If your Delco system can get C-QUAM@ signals, your STEREO light will
come on when you are receiving stereo.
Cassette Deck with Graphic Equalizer
I
Press the PWR button on the radio to turn the unit on. The radio will play
until a cassette is pushed into the cassette entry door (the tape \
side goes in
first.) The cassette deck is built
to work best with tapes that are 30 to 45
minutes long on each side. Tapes longer than that are so thin that they may
not work well in this player.
Once the tape is playing, use the
VOL, BAL and FADE controls on the
radio. The arrows indicate which side
of the tape is being played.

Equalizer
Boost the bass, emphasize a voice in a song, brighten the treble-your
equalizer enables you
to adjust five separate sound frequencies to your
individual taste.

Comfort Controls & Audio Systems
Press (+) to emphasize a frequency, press (-) to de-emphasize it. It’s best
to begin with all the controls in the middle position, then adjust each control
as you like. Observe the
VF display for relative emphasis.
Cr02
This button sets tape bias. When playing high bias chrome or metal tapes,
press
Cr02 (the light in the button will come on). When playing standard
tapes, press the button again (the light will go out).
PROG
To go from one side of the tape to the other, press the PROG button.
Observe the lighted arrows to determine which side of the tape is being
played.
If a tape is inserted with side “1” (or “A”) up, then the up arrow means that
that side is being played. Likewise, a down arrow would indica\
te that side
“2”
(or “By) had been selected. The player will automatically switch to the other
side of the tape when the first side ends.
EJECT
Press EJECT to eject the cassette tape from the player (the radio will t\
hen
play.)

Care of Your Cassette Tape PIayer
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
15 hours of
use. If you notice a reduction in sound quality, try a known good cassette to
see
if the tape or the player is at fault. If this other cassette has no
improvement in sound quality, clean the tape player.
Clean your tape player with a wiping-action, non abrasive clean\
ing cassette,
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.
K1313
Fixed Mast Antenna
The fixed mast antenna can withstand most car washes without b\
eing
damaged.
If the mast should ever become slightly bent, you can straighten \
it
out by hand. If the mast
is badly bent, as it might be by vandals, you should
replace it.
Check every once in a while to be sure the mast is still tightened to the
fender.

Traffic Lights

AM402014
We’re all familiar with traffic lights or stop lights. Often green arrows\
are
being used in the lights for improved traffic control. On some multilane roads,
green arrows light up, indicating that traffic in one or more lanes can move or
make a turn. Green arrows don’t mean “go no matter what,” You’ll still need
to proceed with caution, yielding the right of way to pedestrians and
sometimes to other vehicles.
Some traffic
lights also use red arrows to signify that you must stop before
turning on red.
REVERSIBLE

ROADWAY MULTI-LANE
AM402015
Many city roads and expressways, and even bridges, use reversib\
le-lane
traffic control during rush hours.
A red X light above a lane means no driving
in that lane at that time.
A green arrow means you may drive in that lane.
Look for the signs posted to warn drivers what hours and days these
systems are in effect.

Pavement Markings
NO PASSING ZONE
AM40201 6
Pavement markings add to traffic signs and signals. They give information to
drivers without taking attention from the roadway. A solid yell\
ow line on your
side of the road or lane means “don’t cross.”
Your Own Signals
Drivers signal to others, too. It’s not only more polite, it’s safer, to let other
drivers know what you are doing. And in some places the law requires driver
signals.
Turn and lane change signals: Always signal when you plan to turn or
change lanes.
If necessary, you can use hand signals out the window: Left arm straight out
for
a left turn, down for slow or about-to-stop, and up for a right\
turn.
Slowing down: If time allows, tap the brake pedal once or twice in advance
of slowing or stopping. This warns the driver behind you.
Disabled: Your four-way flashers signal that your vehicle is disabled or \
is a
hazard. See “Hazard Warning Flasher” in the Index.
Traffic Officer
The traffic police officer is also a source of important information. The officer’s
signals govern, no matter what the traffic lights or other signs say. \
The next part discusses some of the road conditions you may e\
ncounter.

AM407001
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 (120 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.

Your Driving and the Road
Most drivers treat their brakes with care. Some, however, overw\
ork the
braking system with poor driving habits.
Avoid needless heavy braking, Some people drive in spurts-heavy \
acceleration followed by heavy braking-rather than keeping pace \
with
traffic. 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.
Don’t “ride” the brakes by letting your left foot rest\
lightly on the brake
pedal while driving.
AM410001
“Riding” your brakes can cause them to overheat to the p\
oint that
h they won’t work well. You might not be able to stop your vehicle in
time to avoid an accident.
If you “ride” your brakes, they will get so
hot they will require a lot of pedal force to slow you down. Avoid
“riding” the brakes.
‘Riding” the brakes wears them
out much faster. You would need costly
wake replacement much sooner than normal, and it also reduces fuel
mnomy.
NOTICE
If you keep pace with the traffic and allow realistic following d\
istances, you
will eliminate a
lot of unnecessary braking. That means better braking and
longer brake life.

Brake System Warning Light
K2325
This light appears on your instrument cluster to warn you if your regular
braking system needs service. See “Brake System Warning Light\
”
in the
Index.
Disc Brake Wear lndicators
Disc brake pads have built-in wear indicators that make a high\
-pitched
warning sound when the brake pads are worn and new pads are \
needed.
The sound may come and go or be heard all the time your veh\
icle is moving
(except when you are pushing on the brake pedal firmly).
I
CAUTION
The brake wear warning sound means that sooner or later your \
your
brakes won’t work well. That could lead to an accident. When you
hear the brake wear warning sound, have your vehicle serviced. \
I
NOTICE
Continuing to drive with worn-out brake pads could result in costly brakt
repair.
ome driving conditions
or climates may cause a brake squeal when the
brakes are first applied or lightly applied. This does
not mean something is
wrong with your brakes.
4-1 7

The traction you can get in a curve depends on the condition of your tires
and the
road surface, the angle at which the curve is banked, and your
speed. While you’re in
a curve, speed is the one factor you can control.
Suppose you’re steering through a sharp curve. Then you suddenly
accelerate. Those two control systems-steering and acceleration-ca\
n
overwhelm those places where the tires meet the road and make \
you lose
control.
What should you do if this ever happens? Let up on the accel\
erator peaal,
steer the vehicle the way you want it
to go, and slow down.
Speed limit signs near curves warn that you should adjust your\
speed. Of
course, the posted speeds are based
on good weather and road conditions.
Under less favorable conditions you’ll want
to go slower.
If you need to reduce your speed as you approach a curve, do it before you
enter the curve, while your front wheels are straight ahead.
Try to adjust your speed so you can “drive” through the curve. Maintain a
reasonable, steady speed. Wait to accelerate until
you are out of the curve,
and then accelerate gently into the straightaway.
When you drive into
a curve at night, it’s harder to see the road ahead of
you because it bends away from the straight beams
of your lights. This is
one
good reason to drive slower.
Steering in Emergencies
There are times when steering can be more effective than braki\
ng. For
example, you come over a hill and find a truck stopped in your lane, or a
car suddenly pulls out from nowhere,
or a child darts out from between
parked cars and stops right in front of you. You can avoid these problems by
braking-if you can stop in time. But sometimes you can’t; there isn’t room.
That’s the time for evasive action-steering around the proble\
m.
Your vehicle can perform very well in emergencies like these. First \
apply your
brakes.
It is better
to remove as much speed as you can from a possible collision.
Then steer around the problem, to the left or right depending \
on the space
available.
An emergency like this requires close attention and a quick decision.
If you
are holding the steering wheel at the recommended
9 and 3 o’clock positions,
you can turn it a full
180 degrees very quickly without removing either hand.
But you have
to act fast, steer quickly, and just as quickly straighten the
4-1 9

Your Driving and the Road
wheel once you have avoided the object. You must then be prep\
ared to steer
back to your original lane and then brake to a controlled stop.
Depending on your speed, this can be rather violent for an un\
prepared driver.
This is one
of the reasons driving experts recommend that you use your
safety belts and keep both hands on the steering wheel.
-
K2218
The fact that such emergency situations are always possible is a good reason
to practice defensive driving at all times.
Off-Road Recovery
You may find sometime that your right wheels have dropped off the edge of
a road onto the shoulder while you're driving.
If the level of the shoulder is only slightly 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 until the right front tire contacts
the pavement edge. Then turn your steering wheel to go straight down the
roadway.
