CD Player Anti-Theft Feature
Delco LOC II@ is an anti-theft feature
for the compact disc player. It can be
used or ignored. If ignored, the system
plays normally. If it is used, your player won’t be usable if it is ever stolen,
because it will go to
LOC mode any
time battery power is removed. It will also go to LOC mode any time power
from the battery is turned
off by the
Battery Rundown Protection feature (see
the
Index under Battery Rundown
Protection). Until an unLOC code is
entered, it will not turn on.
The instructions below tell you how to
enter a secret code into the system. If
your vehicle loses battery power for any reason, you must unlock the system with
the secret code before your audio system
will
turn on.
To Set the Anti-Theft System:
1 . Write down any six-digit number and
keep it in a safe place. This is your
secret code.
2. Turn the ignition to the Accessory or
Run position.
3. Press the PWR button to turn the
radio off.
116
4. Press station preset buttons 1 and 4
at the same time and hold until
“---” appears on the display.
NOTE: You now have only 15 seconds
between each of the following steps.
5. Press SET, and 000 will appear on
the display.
6. Press the SEEK, button until the
first digit of your code appears.
7. Rotate the lower knob right or left
until the second and third digits of
your code appear.
8. Press the lower knob (000 will
appear again on the display).
9. Press the SEEK, button until the
fourth digit of your code appears.
1 0. Rotate the lower knob right or left
until the
fifth and sixth digits of
your code appear.
1 1 . Press the lower knob (rEP will
appear for five seconds, then
000).
12. Repeat steps 6-11. This time SEC
will appear, indicating that Delco
LOC II@ is set, and your audio
system is secure.
To Disable the Anti-Theft System:
Enter your secret code by following
these steps (you will have only
15
seconds between each step).
1 . Turn the ignition to the Accessory or
Run position, and turn the radio off.
2. Press station preset buttons 1 and 4 at
the same time.
SEC will appear on
the display, indicating the audio system is secure.
3. Press SET, and 000 will appear on
the display.
4. Press the SEEK, button until the first digit of your code appears.
5. Rotate the lower knob right or left
until the second and third digits of
your code appear.

6. Press the lower knob (000 will
appear again on the display).
7. Press the SEEK, button until the
fourth digit of your code appears.
8. Rotate the lower knob right or left
until the fifth and sixth digits
of your
code appear.
9. Press the lower knob. If the display
shows
"---", the disabling sequence
was successful (the numbers matched
the user-selected code or
the factory
back-up code) and the audio system is in the
UNSECURED mode. If the
display shows
SEC, the disabling
sequence was unsuccessful and the
numbers did not match either
of the
codes. In this case, the audio system
will remain in the
SECURED mode.
To Unlock the System After a Power
Loss:
When battery power is reapplied to a
secured audio system after a loss of
power, the audio system will not turn on
and
LOC will appear on the digital
display. You will need to unlock the
Delco LOC
II@ system.
1 . Turn the ignition to the Accessory or
Run position, and turn the radio off.
2. Press SET, and 000 will appear on
the display.
3. Follow steps 4-8 for disabling your
anti-theft system.
4. Press the lower knob. The time will
appear on the digital display if you
are successful. If
SEC appears,
however, the numbers did not match
and your audio system is still locked.
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 also pick up noise from things like
storms and power lines.
To lower this
noise, try reducing the treble level.
AM Stereo
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 indicator light will
come on when you are receiving it.

“Riding” the brakes wears them
out much faster. You would need
costly brake replacement
much
sooner than normal, and it also reduces fuel economy. 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 Bmkes (ABS)
Your Pontiac 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 a little while this is going
on. This is the ABS system testing itself.
If you have your foot on the brake
pedal,
this check won’t happen until the vehicle
goes about
4 mph (6 km/h) or until you
take your foot off the brake pedal.

Your Driving and the Road
Anti-Lock Brakes (CONT.)
After an ABS stop, you may also hear a
clicking noise the next time the vehicle
reaches about
4 mph (6 km/h).
If there’s a problem with the anti-lock
brake system, the anti-lock brake system
warning light will stay
on or flash.
See the
Index under Anti-Lock Brake
System Warning Light.

Here’s how anti-lock works. Let’s say
the road is wet. You’re driving safely.
Suddenly an animal jumps out in front
You slam on the brakes. Here’s what
happens with ABS.
A computer senses that wheels are
slowing down. The computer separately
works the brakes at each front wheel
and at the rear wheels.
The anti-lock system can change the
of you.
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
computer keeps receiving updates on
wheel speed and controls braking
pressure accordingly.
Anti-lock doesn’t change the
time you need
to get your foot
the brake pedal. If you get
too close to the vehicle in front
of
I 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.
ProCarManuals.com

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 clicking noise
as you accelerate after a hard stop.
Disc Brake Wear Indicators
Your Pontiac has front disc brakes and
rear drum brakes. 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 vehicle is
moving (except when you are pushing
on the brake pedal firmly).
A
The brake wear warning
sound means that sooner
or
later your brakes won’t work well.
That could lead to an accident.
When you hear the brake wear
warning sound, have your vehicle
serviced.

Brake Aflustment
Every time you make a moderate reverse
brake stop, your brakes adjust for wear.
If you rarely make a moderate or
heavier stop, then your brakes might not
adjust correctly. If you drive
in that way,
then-very carefully-make a few
moderate brake stops about every
1,OOO
miles (1 600 km), so your brakes will
adjust properly.
If your brake pedal goes down farther
than
normal, your rear drum brakes may
need adjustment. Adjust them by
backing up and
firmly applying the
brakes a few times.
Braking In Emergencies
Use your anti-lock braking system when
you need to. 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.
Power Steering -
If you lose power steering assist because
the engine stops or the system fails to
function, you can steer but it will
take
much more effort.

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 braking. 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 problem.
Your Pontiac 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 wheel
once
you have avoided the object. You
must then be prepared 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 unprepared driver.
This is one of the reasons driving
experts recommend that
you use your
safety belts and keep both hands on the
steering wheel.
The fact that such emergency situations
are always possible is a good reason to
practice defensive driving at all times.
ProCarManuals.com

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 Pontiac’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 and an acceleration
skid are best handled by easing your
foot
off the accelerator pedal. If your
vehicle starts to slide (as when you turn
a corner on a wet, snow- or ice-covered
road), ease your foot off the accelerator
pedal as soon as you feel the vehicle
start to slide. Quickly steer the way you
want the vehicle to go.
If you start
steering quickly enough, your vehicle
will straighten out. As it does, straighten
the front wheels.
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. While driving on
a surface with reduced
traction, try your best to avoid sudden
steering, acceleration, or braking
(including engine braking by shifting to
a lower gear). Any sudden change could
cause the tires to slide.
You may not
realize the surface is slippery until your
vehicle is skidding. Learn to recognize
warning clues-such as enough water,
ice or packed snow
on the road to make
a “mirrored surface”-and slow down
when you have any doubt.
Remember: Any anti-lock braking
system
(ABS) helps avoid only the
braking skid.
