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 has been interrupted. 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.

Re,member: 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.
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.
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 the
brakes vibrate,
or YOLI may notice some noise, but
this is normal. Your anti-lock brakes work at all
times
-- whether you are in two-wheel or
four-wheel drive.
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 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.

0 Check your mirrors, glance over your shoulder and
start your left lane change signal before moving out
of the right lane to pass. When you are far enough
ahead of the passed vehicle to see its front
in your
inside mirror, activate your right lane change signal
and move back into the right lane. (Remember that
your right outside mirror is convex. The vehicle you
just passed may seem to be farther away from you
than
it really is.)
Try not to pass more than one vehicle at a time on
two-lane roads. Reconsider before passing the
next vehicle.
Don’t overtake a slowly moving vehicle too rapidly.
Even though the brake lamps are not flashing, it may
be slowing down or starting to turn.
0 If you’re being passed, make it easy for the
following driver to get ahead of you. Perhaps
you
can ease a little to the right.
Loss of Control
Let’s review what driving experts say about what
happens
when the three control systems (brakes, steering
and acceleration) don’t have enough friction where the
tires meet the road
to do what the driver has asked.
In any emergency, don’t give up. Keep trying
to steer
and constantly seek an escape route or area of
less danger.
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 and an acceleration skid are best
handled by easing your foot off the accelerator pedal.

Traveling to Remote Areas
It makes sense to plan your trip, especially when going
to
a remote area. Know the terrain and plan your route.
You are much less likely to get bad surprises. Get
accurate maps of trails and terrain. Try to learn of any
blocked
or closed roads.
It’s also a good idea to travel with at least one other
vehicle.
If something happens to one of them, the other
can help quickly.
Getting Familiar with Off-Road Driving
It’s a good idea to practice in an area that’s safe and
close
to home before you go into the wilderness.
Off-road driving does require some new and different
driving skills. Here’s what we mean.
Tune your senses to different kinds of signals. Your
eyes, for example, need to constantly sweep the terrain
for unexpected obstacles. Your ears need to listen for
unusual tire or engine sounds. With your arms, hands,
feet and body.
you‘ll need to respond to vibrations and
vehicle bounce. Controlling
your vehicle is the
key to successful
off-road driving. One
of the best ways to control your
vehicle is
to control your speed. Here are some things to
keep
in mind. At higher speeds:
0 you approach things faster and you have less time to
scan the terrain for obstacles.
0 you have less time to react.
0 you have more vehicle bounce when you drive
over obstacles.
0 you’ll need more distance for braking, especially
since you’re on an unpaved surface.
A c. u7c-i:
When you’re driving off-road, bouncing and
quick changes in direction can easily throw you
out of position. This could cause you
to lose
control and crash.
So, whether you’re driving on
or off the road, you and your passengers should
wear safety belts.

Scanning the Terrain
Off-road driving can take you over many different kinds
of terrain.
You need to be familiar with the telrain and its
many different features. Here are some things to consider.
S~lr$uce Conditions. Off-roading can take you over
hard-packed dirt, gravel, rocks, grass, sand, mud, snow
or ice. Each of these surfaces affects the steering,
acceleration and braking of your vehicle
in different
ways. Depending upon the kind of surface
you are on,
you may experience slipping, sliding, wheel spinning,
delayed acceleration, poor traction and longer
braking distances.
Su$ace Obstucles . Unseen or hidden obstacles can be
hazardous.
A rock, log, hole, rut or bump can startle you if
you're not prepared for them. Often these obstacles are
hidden by grass, bushes, snow
or even the rise and fall of
the terrain itself. Here are
some things to consider:
0 Is the path ahead clear'?
Will the surface texture change abruptly up ahead?
Does the travel take you uphill or downhill? (There's
more discussion of these subjects later.)
Will you have to stop suddenly or change
direction quickly'? When you
drive over obstacles or rough terrain, keep
a
firm grip on the steering wheel. Ruts, troughs or other
surhce features can jerk the wheel out
of your hands if
you're not prepared.
When you drive over bumps, rocks, or other obstacles,
your wheels can leave the ground.
If this happens, even
with one or two wheels, you can't control the vehicle as
well or at all.
Because you
will be on an unpaved surface, it's
especially important to avoid sudden acceleration,
sudden turns or sudden braking.
In a way, off-road driving requires a different kind of
alertness from driving on paved roads and highways.
There are no road signs, posted speed limits or signal
lights.
You have to use your own good judgment about
what is safe and what isn't.
Drinking and driving can be very dangerous
on any
road. And this is certainly true for off-road driving. At
the very time
you need special alertness and driving
skills, your reflexes, perceptions and judgment can be
affected by even
a small amount of alcohol. You could
have a serious
-- or even fatal -- accident if you drink
and drive or ride with a driver who has been drinking.
See "Drunken Driving"
in the Index.

Payload
The payload capacity is shown on the CertificationRire
label. This is the maximum load capacity that your
vehicle can carry. Be sure to include the weight of the
occupants as part
of your load. If you added any
accessories or equipment after your vehicle left the
factory, remember to subtract the weight
of these things
from the payload.
Your dealer can help you with this.
Electronic Level Control
The rear of the vehicle is automatically kept level as you
load
or unload your vehicle. However, you should still
not exceed the
GVWR or the GAWR.
The ignition has to be on for the level control to work.
The system includes a small electric air compressor and
air-adjustable rear shock absorbers.
You may hear the compressor operating when you load
or unload your vehicle, and periodically
as the system
self-adjusts. This is normal. The compressor should operate for
brief periods
of time
If the sound continues for an extended period of time,
your vehicle needs service.
To keep your battery from
being drained. you may want to remove the
LD LEV
fuse in the fuse control panel until you can get your
vehicle serviced (see “Fuses and Circuit Breakers”
in
the Index).
Using heavier suspension components to get added
durability might not change your weight ratings.
Ask
your dealer to help you load your vehicle the right way.
NOTICE:
Your warranty does not cover parts or
components that fail because
of overloading.

Every vehicle is ready for some trailer towing. If yours
was built with trailering options, as many are, it’s ready
for heavier trailers. But trailering is different than just
driving your vehicle by itself. Trailering means changes
in handling, durability and fuel economy. Successful,
safe trailering takes correct equipment, and
it has to be
used properly.
That’s
the reason for this part. In it are many
time-tested, important trailering tips and safety rules. Many
of these are important for your safety and that of
your passengers.
So please read this section carefully
before you pull a trailer.
If You Do Decide To Pull A Trailer
If you do, here are some important points:
0
0
There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure
your rig will be legal, not only where you live but
also where you’ll be driving.
A good source for this
information can be state or provincial police.
Consider using a sway control if your trailer
will
weigh 2,000 lbs. (900 kg) or less. You should always
use a sway control if your trailer will weigh more
than
2,000 Ibs. (900 kg). You can ask a hitch dealer
about sway controls.

Don’t tow a trailer at all during the first 500 miles
(800 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.
Then, during the first
500 miles (800 km) that you
tow a trailer, don’t drive over 50 mph (80 km/h) and
don’t make starts at full throttle. This helps your
engine and other parts of
your vehicle wear in at the
heavier loads.
You should use DRIVE
(D) (or, as you need to, a
lower gear) when towing a trailer. Operating your
vehicle
in DRIVE (D) when towing a trailer will
minimize heat buildup and extend the life
of
your transmission.
Three important considerations have to
do with weight:
the weight of the trailer,
0 the weight of the trailer tongue
0 and the weight on your vehicle’s tires.

4. Raise the vehicle by turning the jack handle to the
right. Raise the vehicle
far enough off the ground so
there is enough room for the spare tire to fit.
5. Remove all the wheel nuts and take off the flat tire.
6. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could come
off and cause an accident. When you change
a
wheel, remove any rust or dirt from the places
where the wheel attaches to the vehicle. In an
emergency, you can use a cloth
or a paper towel
to do this; but be sure to use
a scraper or wire
brush later, if you need to, to get all the rust or
dirt
off.
