Theft-Deterrent Feature
THEFTLOCKžis designed to discourage theft of your
radio. It works by using a secret code to disable all radio
functions whenever battery power is interrupted.
If THEFTLOCK
žis active, the THEFTLOCKžindicator
will ¯ash when the ignition is off.
The THEFTLOCK
žfeature 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
žis
activated, your radio will not operate if stolen.
When THEFTLOCK
žis 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 THEFTLOCKžsystem. Read
through all nine steps before starting the procedure.
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 on.
3. Turn the radio off.
4. Press the 1 and 4 pushbuttons at the same time.
Hold them down until --- shows on the display.
Next you will use the secret code number which you
have written down.
5. Press MIN and 000 will appear on the display.
6. Press MIN again to make the last two digits agree
with your code.
7. Press HRS to make the ®rst one or two digits agree
with your code.
8. Press AM-FM after you have con®rmed 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 con®rm
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 Ð heavy acceleration followed by heavy
braking Ð 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 Brake System (ABS)
Your vehicle may have anti-lock brakes. ABS is an
advanced electronic braking system that will help
prevent a braking skid.
If your vehicle has anti-lock brakes, this warning light on
the instrument panel will come on brie¯y when you
start your vehicle.
When you start your engine, or when you 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 or pulses a little. This is normal.United States

Let's say the road is wet and you're driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. 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 wheel.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. This can help you 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
®rmly and let anti-lock work for you. You may feel a
slight brake pedal pulsation or notice some noise, but
this is normal.
Braking in Emergencies
At some time, nearly every driver gets into a situation
that requires hard braking.
If you have anti-lock, you can steer and brake at the
same time. However, if you don't have anti-lock,
your ®rst reaction Ð to hit the brake pedal hard andhold it down Ð may be the wrong thing to do. Your
wheels can stop rolling. Once they do, the vehicle can't
respond to your steering. Momentum will carry it in
whatever direction it was headed when the wheels
stopped rolling. That could be off the road, into the very
thing you were trying to avoid, or into traffic.
If you don't have anti-lock, use a ªsqueezeº braking
technique. This will give you maximum braking while
maintaining steering control. You can do this by pushing
on the brake pedal with steadily increasing pressure.
In an emergency, you will probably want to squeeze the
brakes hard without locking the wheels. If you hear or
feel the wheels sliding, ease off the brake pedal.
This will help you retain steering control. If you
dohave
anti-lock, it's different. See ªAnti-Lock Brake Systemº
in this section.
In many emergencies, steering can help you more than
even the very best braking.
4-9

Suppose you're steering through a sharp curve.
Then you suddenly apply the brakes. Both control
systems Ð steering and braking Ð have to do their work
where the tires meet the road. Unless you have
four-wheel anti-lock brakes, adding the hard braking can
demand too much of those places. You can lose control.
The same thing can happen if you're steering through a
sharp curve and you suddenly accelerate. Those two
control systems Ð steering and acceleration Ð can
overwhelm those places where the tires meet the road
and make you lose control. See
Enhanced Traction
System (ETS) on page 4-10.
What should you do if this ever happens? Ease up on
the brake or 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 ªdriveº 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 ®nd 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 Ð if you can stop in time. But
sometimes you can't; there isn't room. That's the time for
evasive action Ð steering around the problem.
Your vehicle can perform very well in emergencies like
these. First apply your brakes Ð but, unless you
have anti-lock, not enough to lock your wheels. See
Braking on page 4-6. 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.
