Playing 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 should face to the
right.
If the ignition is on, but the radio is off, the tape
will begin playing. If you hear nothing but a garbled
sound, the tape may not be in squarely. Press EJECT to
remove the tape and start over.
While the tape
is playing, use the VOL, FADE, BAL,
TREB and BASS controls just as you do for the radio.
The display will show TP with a
box around it and an
arrow to show which side
of the tape is playing. Your
tape bias is set automatically. When a metal or
chrome tape is inserted, HI-BIAS appears on the
display.
If you want to insert a tape when the ignition is
off, first press EJECT or RCL.
If E and a number appear on the radio display, the tape
won’t play because of an error.
ElO: The tape is tight and the player can’t turn the
tape hubs. Remove the tape. Hold the tape with the
open end down and try to turn the right hub
counterclockwise with a pencil. Turn the tape over
and repeat. If the hubs do not turn easily, your tape
may be damaged and should not be used in the
player. Try a new tape to make sure your player
is
working properly.
0 Ell: The tape is broken. Try a new tape.
If any error occurs repeatedly or if an error can’t be
corrected, please contact your retailer. If your radio
displays an error number, write it down and provide it to
your retailer when reporting the problem.
REV (1): Press this button to reverse the tape rapidly.
Press

Theft-Deterrent Feature
THEFTLOCK TM 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
7. Press HR to make the first one or two digits agree
with
your code.
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.

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
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, and you may even notice that your brake
pedal moves a little. This is normal.

ANT‘- (@)
If there’s a problem with the
anti-lock brake system, this
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. 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 computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
4-8

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 hear a motor or
clicking noise during a hard stop, but this is normal.
Traction Control System
Your vehicle has a traction control system that limits
wheel spin. This is especially useful in slippery road
conditions. The system operates only if it senses that one
or both of the front wheels are spinning or beginning to
lose traction. When this happens, the system works the
front brakes and reduces engine power to limit
wheel spin.
TRACTION ACTIVE
This light will come on
when your traction control
system is limiting wheel
spin. See “Traction Control
System Active Light” in
the Index.
You may feel or hear the system working, but this
is normal.
If your vehicle is in cruise control when the traction
control 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 the cruise control. (See “Cruise Control”
in
the Index.)

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.
Magnasteer TM
Your vehicle is equipped with GM Magnasteer TM, a
steering system that continuously adjusts the effort you
feel when steering at all vehicle speeds. It provides ease
when parking yet a firm, solid feel at highway speeds.
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.
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. Both control
systems
-- steering and acceleration -- have to do their
work where the tires meet the road. Adding the sudden
acceleration can demand
too much of those places. You
can lose control. Refer to “Traction Control System” in
the Index.
What should you do if this ever happens? Ease up on the
accelerator pedal, 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.
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 Aurora can perform very well in emergencies like
these. First apply your brakes. (See “Braking in
Emergencies” earlier in this section.)
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.
The fact that such emergency situations are always
possible is a good reason
to practice defensive driving at
all times and wear safety belts properly.
