Theft-Deterrent Feature
THEFlLOCK@ 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 THEFIZOCK 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 THEFIZOCK is
activated, your radio will not operate if stolen.
When
THEFI'LOCK 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
THEFI'LOCK 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

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, 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.
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. 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.
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
firmly and let anti-lock work for you. You may feel a
slight brake pedal pulsation
or notice some noise, but
this is normal.
Enhanced Traction System
If your vehicle has the optional four-speed automatic
transaxle,
it also has an Enhanced Traction System
(ETS) 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 reduces engine power and may also upshift the
transaxle
to limit wheel spin.
LOW
TRAC
This light will come on
when your Enhanced
Traction System
is limiting
wheel spin. See “Enhanced
Traction System Active
Light” in the Index.
You may
feel or hear the system working, but this
is normal.
The Enhanced Traction System operates
in all transaxle
shift lever positions. But the system can upshift the
transaxle only as high
as the shift lever position you’ve
chosen,
so you should use the lower gears only when
necessary. See “Automatic Transaxle” in the Index.
ETS
OFF
When the system is on and
the parking brake is fully
released,
this warning light
will come on to let you
know
if there’s a problem
with the system.
See “Enhanced Traction System
Warning Light” in the
Index. When
this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
4-9

To limit wheel spin, especially in slippery road
conditions, you should always leave the Enhanced
Traction System
on. But you can turn the system off if
you ever need to. (You should turn the system off if your
vehicle ever gets stuck in sand, mud, ice
or snow. See
“Rocking Your Vehicle” in
the Index.)
To turn the system on or off,
press the button on the shift
lever knob.
When
you turn the system off, the Enhanced Traction
System warning light will come on
and stay on. If the
Enhanced Traction System is limiting wheel spin when
you press the button to
turn the system off, the warning
light will come on
-- but the system won’t turn off right
away. It
will wait until there’s no longer a current need
to limit wheel spin. You
can turn the system
back on at any time by pressing
the button again. The Enhanced Traction System
warning light should go off.
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.
Variable Effort Steering (If Equipped)
This steering system provides lighter steering effort for
parking and at low vehicle speeds. Steering effort will
increase at higher speeds for improved road feel.
4-10

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 vehicle 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.
4112

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 vehicle’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 is best handled by easing your foot off
the accelerator pedal.
If you have the Enhanced Traction System, remember: It
helps avoid only the acceleration skid.
If you do not have the Enhanced Traction System, or if
the system is
off, then an acceleration skid is also best
handled
by easing your foot off the accelerator pedal.
If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want
the
vehicle to go. If you start steering quickly enough, your
vehicle may straighten out. Always be ready for
a
second skid if it occurs.
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 changes 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 brake system
(ABS) helps
avoid only the braking
skid.
4-15

Your anti-lock brakes improve your vehicle’s stability
when you make a hard stop on a slippery road. Even
though you have the anti-lock braking system, you’ll
want to begin stopping sooner than you would on
dry
pavement. See “Anti-Lock” in the Index.
Allow greater following distance on any
slippery road.
Watch for slippery spots. The road might be fine
until you
hit a spot that’s covered with ice. On an
otherwise clear road, ice patches may appear in
shaded areas where the sun can’t reach: around
clumps of trees, behind buildings or under bridges.
Sometimes the surface of a curve or an overpass may
remain icy when the surrounding roads are clear. If you see
a patch of ice ahead of you, brake before you
are on
it. Try not to brake while you’re actually on
the ice, and avoid sudden steering maneuvers.
If You’re Caught in a Blizzard
If you are stopped by heavy snow, you could be in a
serious situation. You should probably stay
with your
vehicle
unless you know for sure that you are near help
and you can hike through the snow. Here are some
things to do to summon help and keep yourself and your
passengers safe:
Turn on your hazard flashers.
