Playing the Radio
PWR-VOL:
Press this knob to turn the system on and
off. To increase volume, turn the knob clockwise. Turn
it counterclockwise to decrease volume. The knob is
capable of rotating continuously.
RECALL: Display the time with the ignition off by
pressing this button. When the radio is playing, press
this button to recall the station frequency.
SCV Your system has a feature called
Speed-Compensated-Volume (SCV). With SCV, your
audio system adjusts automatically to make up for road
and wind noise as you drive. Set the volume at the
desired level. Move the control ring behind the upper
knob clockwise to adjust the SCV. Then, as you drive,
SCV automatically increases the volume,
as necessary,
to overcome noise at any particular speed. The volume
level should always sound the same to you
as you drive.
If you don't want to use
SCV, turn the control all the
way down. Each detent
on the control ring allows for
more volume compensation at a faster rate
of speed.

Theft-Deterrent Feature
THEFTLOCK” is designed to discourage theft of your
radio.
It works by using a secret code to disable all radio
functions whenever battery power is removed.
The THEFTLOCK feature for the radio may be used or
ignored.
If ignored, the system plays normally and the
radio
is not protected by the feature. If THEFTLOCK is
activated, your radio
will not operate if stolen.
When THEFTLOCK is activated, the radio will display
LOC to indicate a locked condition anytime battery
power is removed. If your battery loses power for any
reason, you must unlock the radio with the secret code
before
it will operate.
Activating the Theft-Deterrent Feature
The instructions which follow, explain how to enter your
secret code to activate the THEFTLOCK system.
It is
recommended that you read through all nine steps
before starting the procedure.
NOTE: If you allow more than
15 seconds to elapse
between any steps, the radio automatically reverts to
time and you must start the procedure over at Step 4.
1. Write down any three or four-digit number from
000 to 1999 and keep it in a safe place separate from
the vehicle.
2. Turn the ignition to ACCESSORY or RUN.
3. Turn the radio off.
4. Press the 1 and 4 buttons together. Hold them down
until --- shows on the display. Next you will use the
secret code number which you have written down.
5. Press MN and 000 will appear on the display.
6. Press MN again to make the last two digits agree
with your code.
7. Press HR to make the first one or two digits agree
with your code.
8. Press AM-FM after you have confirmed that the
code matches the secret code you have written down.
The display
will show REP to let you know that you
need to repeat Steps
5 through 7 to confirm your
secret code.
9. Press AM-FM and this time the display will show
SEC to let you know that your radio
is secure. The
indicator by the volunle control
will begin flashing
when the ignition is turned off.

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). 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.
Tips About Your Audio System
Hearing damage from loud noise is almost undetectable
until it is too late. Your hearing can adapt to higher
volumes of sound. Sound that seems normal
can be loud
and harmf~ll to your hearing. Take precautions by
adjusting the volume control on your radio to
a safe
sound level before your hearing adapts to
it.
To help avoid hearing loss or damage:
Adjust the volume control to the lowest setting.
Increase volume slowly until you hear comfortably
and clearly.
NOTICE:
Before you add any sound equipment to your
vehicle
-- 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. Your vehicle’s systems may interf‘ere
with the operation
of sound equipment that has
been added improperly.
So, before adding sound equipment, check with
your retailer and be sure to check Federal rules
covering mobile radio and telephone units.

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. 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 vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that
will help
prevent a braking skid.
When you start your engine and begin to drive away,
your anti-lock brake system will check itself. You
may
hear a momentary motor or clicking noise while this test
is going on. This
is normal.
If there’s a problem with the
anti-lock brake system, this
warning light will stay on.
System Warning Light” in
the Index.
ANTI - LOCK See “Anti-Lock Brake
ProCarManuals.com

Here’s how anti-lock works. Let’s say the road is wet.
You’re driving safely. Suddenly an animal jumps out
in
front of you.
You slam
on the brakes. Here’s what happens with ABS.
A computer senses that wheels are slowing down. If one
of the wheels is about to stop rolling, the computer
will
separately work the brakes at each front wheel and at the
rear wheels. The anti-lock system can change the brake
pressure faster
than any driver could. The computer is programmed to
make the most of available tire and road conditions.
You can steer around the obstacle while braking hard.
As you brake, your cornputer keeps receiving updates on
wheel speed and controls braking pressure accordingly.

ProCarManuals.com

Remember: Anti-lock doesn’t change the time you need
to get your foot
up to the brake pedal or always decrease
stopping distance.
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.
Using Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down
and let anti-lock work for you.
You may feel the brakes
vibrate, or you may notice some noise, but this is normal.
Braking in Emergencies
With anti-lock, you can steer and brake at the same
time.
In many emergencies, steering can help you more
than even the very best braking.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is
not functioning, you can steer but
it will take much more effort.
Steering Tips
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. Here’s why:
Experienced driver or beginner, each
of us is subject to
the same laws of physics when driving
on curves. The
traction
of the tires against the road surface makes it
possible for the vehicle to change its path when you turn
the front wheels.
If there’s no traction, inertia will keep
the vehicle going in the same direction.
If you’ve ever
tried to steer a vehicle on wet ice,
you’ll understand this.
