1. Stop your vehicle.
2. Drive 7 feet (2 m) in the direction opposite to the
direction
you were driving before you stopped.
3. Then, press
the clutch if you have a manual
transmission, and shift the transfer case to
TWO-WHEEL HIGH (2H). The hubs will unlock.
Transfer Case
E

The transfer case shift lever is on the floor to the right
of the driver.
Use this lever to shift into and out of
four-wheel drive.
An indicator light comes on when
the transfer case is in FOUR-WHEEL HIGH (4H) or
FOUR-WHEEL LOW (4L).
TWO-WHEEL HIGH (2H): This setting is for driving
in
most street and highway situations. Your front axle is
not engaged in two-wheel drive.
FOUR-WHEEL HIGH (4H): This setting engages
your front axle to help drive your vehicle. Use
FOUR-WHEEL HIGH (4H) when you need extra
traction, such as on wet or icy roads,
or in most off-road
situations.
NEUTRAL (N): Shift to this setting only when your
vehicle needs to be towed.
FOUR-WHEEL LOW (4L): This setting also engages
your front axle to give you extra traction and can be
used for driving downhill, uphill or on rocky terrain
when you’re driving slower than 35 mph (55
km/h).
Remember that driving in FOUR-WHEEL HIGH (4H)
or FOUR-WHEEL LOW (4L) may reduce fuel
economy. Also, driving in four-wheel drive on
dry
pavement could cause your tires to wear faster and make
your transfer case harder to shift.

You have three systems that make your vehicle go where
you want it to go. They
are the brakes, the steering and
the accelerator. All three systems have to do their work
at the places where the tires meet the road.
Sometimes, as when you’re driving on snow or ice, it’s
easy to ask more of those control systems than the tires
and road can provide. That means you can lose control
1 of your vehicle.
~~ ~~~~~~~~~
Braking
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That’s
perception time. Then you have to bring up your
foot and do it. That’s
reaction time.
Average reaction time is about 3/4 of a second. But
that’s only an average. It might be less with one driver
and as long
as two or three seconds or more with
another. Age, physical condition, alertness, coordination
and eyesight all play
a part. So do alcohol, drugs and
frustration. But even in
3/4 of a second, a vehicle
moving at
60 mph (100 kmk) travels 66 feet (20 m).
That could be a lot of distance in
an, emergency, so
keeping enough space between your vehicle and others
is important.
And, of course, actual stopping distances vary greatly
with the surface of the road (whether it’s pavement or
gravel); the condition of the road (wet, dry, icy); tire
tread; the condition of your brakes; the weight of the
vehicle and the amount of brake force applied.

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.
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 apply the brakes. Both control
systems
-- steering and braking -- 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
-- steering and acceleration -- can
overwhelm those places where the tires meet the road and make you lose control.
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 “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.

Downloaded from www.Manualslib.com manuals search engine 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.
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.
If you have the anti-lock braking system, remember: It
helps avoid only the braking
skid. If you do not have
anti-lock, then in a braking skid (where the wheels are
no longer rolling), release enough pressure on the brakes to get
the wheels rolling again. This restores steering
control. Push the brake pedal down steadily when you
have
to stop suddenly. As long as the wheels are rolling,
you will have steering control.

Downloaded from www.Manualslib.com manuals search engine Before You Go Off-Roading
There are some things to do before you go out. For
example, be sure to have all necessary maintenance and service work done. Check to make sure all underbody
shields (if
so equipped) are properly attached. Be sure
you read all the information about your
four-wheel-drive vehicle in this manual. Is there enough
fuel?
Is the spare tire fully inflated? Are the fluid levels
up where they should be? What are the local laws that
apply to off-roading where you’ll be driving? If you
don’t know, you should check with law enforcement
people in the area. Will you be on someone’s private land? If
so, be sure to get the necessary permission.
Loading Your Vehicle for Off-Road Driving
There are some important things to remember about
how
to load your vehicle.
The heaviest things should be on the load floor and
forward of your rear axle. Put heavier items as far
forward as you can.
Be sure the load is secured properly, so driving on
the off-road terrain doesn’t
toss things around.
Cargo on the load floor piled higher than
the seatbacks can be thrown forward
during a sudden stop. You or your
passengers could be injured. Keep cargo
below the top of the seatbacks.
Unsecured cargo on the load floor can be
tossed about when driving over rough
terrain. You
or your passengers can be
struck by flying objects. Secure the
cargo properly.
Heavy loads on the roof raise the vehicle’s
center of gravity, making
it more likely to
roll over. You can be seriously or fatally
injured if the vehicle rolls over.
Put heavy
loads inside the cargo area, not on the roof.
Keep cargo in the cargo area
as far forward
and low as possible.
You’ll find other important information in this manual. See “Vehicle Loading,” “Luggage Carrier” and “Tires\
”
in the Index.

Downloaded from www.Manualslib.com manuals search engine Driving Across an Incline
Sooner or later, an off-road trail will probably go &crW$
the incline of a hill.
If this happens, you have to decide
whether to try to drive across the incline. Here are some
things to consider:
0 A hill that can be driven straight up or down may be
too steep to drive across. When you go straight up or
down a hill, the length of the wheel base (the
distance from the front wheels to the rear wheels)
reduces the likelihood the vehicle will tumble end
over end. But when you drive across an incline, the
much more narrow track width (the distance between
the left and right wheels) may not prevent the vehicle
from tilting and rolling over. Also, driving across an
incline puts more weight on the downhill wheels.
This could cause a downhill slide or a rollover.
0 Surface conditions can be a problem when you drive
across a hill. Loose gravel, muddy spots, or even wet
grass can cause your tires to slip sideways, downhill.
If the vehicle slips sideways,
it can hit something
that will trip
it (a rock, a rut, etc.) and roll over.
Hidden obstacles can make the steepness of the
incline even worse. If
you drive across a rock with
the uphill wheels, or if the downhill wheels drop into
a rut or depression, your vehicle can tilt even more.
For reasons like these, you need to decide carefully
whether to try to drive across an incline. Just because
the trail goes across the incline doesn’t mean you
have to drive it. The last vehicle to try it might have
rolled over.
A CAUTION:
Driving across an incline that’s too steep will
make your vehicle roll over. You could be
seriously injured or killed.
If you have any doubt
about the steepness
of the incline, don’t drive
across it. Find another route instead.

Downloaded from www.Manualslib.com manuals search engine Driving in Mud, Sand, Snow or Ice
When you drive in mud, snow or sand, your wheels
won’t get good traction. You can’t accelerate as
quickly, turning is more difficult, and you’ll need
longer braking distances.
It’s best to use a low gear when you’re in mud
-- the
deeper the mud, the lower the gear. In really deep mud,
the idea
is to keep your vehicle moving so you don’t
get stuck.
When you drive on sand, you’ll sense
a change in wheel
traction. But it will depend upon how loosely packed the
sand is. On loosely packed sand (as on beaches or sand
dunes) your tires will tend to sink into the sand. This has
an effect on steering, accelerating and braking.
You may
want to reduce the air pressure in your tires slightly
when driving on sand. This will improve traction. Hard packed snow and ice offer
the worst tire traction.
On these surfaces, it’s very easy to lose control. On wet
ice, for example, the traction is so poor that you will
have difficulty accelerating. And if you do get moving,
poor steering and difficult braking can cause
you to slide
out
of control.
Driving on frozen lakes, ponds or rivers can be
dangerous. Underwater springs, currents under
the ice, or sudden thaws can weaken the ice. Your
vehicle could fall through the ice and you and
your passengers could drown. Drive your vehicle
on safe surfaces only.

Downloaded from www.Manualslib.com manuals search engine Driving in Water
Light rain causes no special off-road driving problems. But heavy rain can mean flash flooding, and flood
waters demand extreme caution.
Find out how deep the water is before you drive through
it.
If it’s deep enough to cover your wheel hubs, axles or
exhaust pipe, don’t try it
-- you probably won’t get
through. Also, water that deep can damage your axle
and other vehicle parts.
If the water isn’t too deep, then drive through it slowly.
At fast speeds, water splashes on your ignition system
and your vehicle can stall. Stalling can also occur if you
get your tailpipe under water. And, as long as your
tailpipe is under water, you’ll never be able
to start your
engine. When you
go through water, remember that
when your brakes get wet, it may take you longer
to stop.
A CAUTION:
Driving through rushing water can be dangerous.
Deep water can sweep your vehicle downstream
and you and your passengers could drown.
If it’s
only shallow water, it can still wash
away the
ground from under your tires, and you could lose
traction and roll the vehicle over. Don’t drive
through rushing water.
