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.

Anti-Lock Brakes (ABS)
If there’s ;1 problem with the
anti-lock
brake system. this
warning light
will stay on.
See “Anti-Lock Brake
System Warning Light”
in
the Index.

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. I
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. You
can steer
around the obstacle while braking hard.
As you brake. your colnputer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
4-8

An emergency like this requires close attention and a
quick decision. If yo^^ 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
SLICII emergency situations are always
possible is
a good rwson to practice defensive driving at
all times and wear safety belts properly.
Off-Road Recovery
I OFF- ROAD RECOVERY / ,+
-/// edge of paved surface
If the level of the shoulder is only slightly below the
pwement, recovery should
be fairly easy. Ease off the
accelerator and then,
if there is nothing in the way, steer so
that your vehicle straddles the edge of the pavement. YOLI
can turn the steering wheel up to one-quarter turn until the
right front
tire contacts the pavement edge. Then turn your
steering wheel
to go straight down the roadway.
4-11

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 il 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 lilnited.
While driving
on a surface with reduced traction. try
your best to avoid sudden steering, acceleration
or
braking (inclucling engine braking by shifting to a lower
gear).
Any sudden changes could cause the tircs lo slide.
You may not realize the surface is slippery until yo11r
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.
Driving Guidelines
This multipurpose passenger vehicle is defined as a utility
vehicle in Consumer Information Regulations issued by
the National Highway Traffic Safety Administration (NHTSA)
of the United States Department of
Transportation.
Utility vehicles have higher ground
clearance
and a narrower track to make them capable of
performing
in a wide variety of off-road applications.
Specific design characteristics give them
a higher center of
gravity than ordinary cars. An advantage of the higher
ground clearance is
a better view of the road allowing yo11
to anticipate problems. They are not designed for
cornering at the same speeds
as conventional
two-wheel-drive vehicles any more than low-slung sports cars are dcsigned
to perform satisfactorily under off-road
conditions.
If at all possible. avoid shalp turns or abrupt
manewers. As with other vehicles
of this type. failure to
operate this vehicle correctly may result
in loss of control
or vehicle rollover.
4-14

What's the worst time for this'? "Wet ice." Very cold
snow
or ice can be slick and hard to drive on. But wet
ice can be
even more trouble because it may offer the
least traction
of all. You can get wet ice when it's about
freezing
(32°F; 0°C) and freezing rain begins to fill.
Try to avoid driving on wet ice until salt and sand crews
can get there. Whatever
me condition
-- smooth ice, packed, blowing.
or loose snow -- drive with caution.
Accelerate gently. Try not to break the fragile traction. If
you accelerate
too fist, the drive wheels will spin and
polish the surface under the tires even more.
Your anti-lock brakes improve your vehicle's stability
when
you make a hard stop on a slippery road. Even
though
you have an 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.
4-3s

Snow can trap exhaust gases under your vehicle.
This can cause deadly
CO (carbon monoxide) gas
to get inside.
CO could overcome you and kill
you. You can’t see it or smell it,
so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn’t collect there.
Open a window just a little on the side of the
vehicle that’s away from the wind. This will help
keep
CO out.
Run your engine only as long as you must. This saves
fuel. When
you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly.
This
uses less fuel for the heat that you get and it keeps the
battery charged.
You will need a well-charged battery to
restart the vehicle. and possibly for signaling later on
with your headlamps. Let the heater run for a while.
Then, shut the engine
off and close the window almost
all the way
to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold.
But do it as little as possible. Preserve the
fuel as long
as you can. To help keep warm, you can get
out of the vehicle and
do some hirly vigorous exercises
every half
hour or so until help comes.

3.
3.
Set the par' * lg brake firmly.
Place an automatic transmission
in PARK (P) or a
manual transmission in FIRST ( I ).
Firmly attach the vehicle being towed to the tow
vehicle.
Do not tow the vehicle by the rear bumper
bar. Refer
to the hitch manufacturer's instructions.
Place the manual shift transfer case shift lever
in
NEUTRAL (N).
A CAUTION:
Shifting the transfer case into NEUTRAL (N) can
cause your vehicle to roll even if the transmission
is
in PARK (P), for an automatic transmission, or
if your vehicle is in gear, for a manual
transmission. You
or others could be injured.
Make sure the parking brake
is firmly set before
you shift the transfer case into
NEUTRAL (N).
5. Release the parking brake only after the vehicle
being towed is firmly attached
to the tow vehicle.
6. Insert the ignition key into the ignition switch and
turn
it one notch forward of the LOCK position. This
places the key
in the OFF position, which unlocks
the steering column while preventing battery drain.
Unlocking the steering column will allow
for proper
movement
of the front wheelshires during towing.
4-41

When your vehicle is being towed. have the ignition key
turned to the OFF position. The steering wheel should
be cla111ped
in a straight-alwad position with a clamping
device designed for towing service. Do not use the
vehicle's steering column lock for this. The transmission
should be
in NEUTRAL (N) and the transfer case, if you
have one. should be in 2HI. The parking brake should
be released.
If your vehicle 11as a floor mounted shifter and no
electrical power, the electrical solenoid lock must be
overridden to shift from PARK (P) to NEUTRAL (N).
Follow these steps:
1. Push the base of the shift lever boot forward \%7ith
your tlwmb.
2. Lift the boot and find the white solenoid lever.
