1. The vehicle must be moving less than 3 mph
(4.8
kmh) with the transmission in NEUTRAL (N)
for an automatic transmission. For a manual
transmission, the clutch pedal must be engaged.
The preferred method for shifting into
or out of 4LO
is to have your vehicle moving 1 to 2 mph (1.6 to
3.2 km/h).
2. Press the transfer case shift button and shift in one
continuous motion.

Remember that driving
in 4HI or 4LO 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 and reduce
powertrain longevity.
Electronic Transfer Case (U' Equipped)

vehicle has the electronic
transfer case,
the transfer

You can choose among three driving settings:
2HI: This setting is for driving in most street and
highway situations. Your front axle is not engaged in
two-wheel drive. When this lamp
is lit, it is about
one-half
as bright as the others.
4HI: This setting engages your front axle to help drive
your vehicle. Use
4HI when you need extra traction, such
as on snowy or icy roads, or in most off-road situations.

Downloaded from www.Manualslib.com manuals search engine Control of a Vehicle
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.
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 314 of a second, a vehicle
moving
at 60 mph (100 km/h) 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.
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
of your vehicle.

Downloaded from www.Manualslib.com manuals search engine 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
and let anti-lock work for you. You may feel the brakes
vibrate, or you may notice some noise, but this is
normal. On vehicles
with four-wheel drive, your
anti-lock brakes work at all times
-- whether you are in
two-wheel drive 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
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.
4-9

Downloaded from www.Manualslib.com manuals search engine Suppose you‘re steering through a sharp curve. Then you
suddenly accelerate.
Both control systems -- steering and
acceleration
-- have to do their work where the tires meet
the road. Adding the sudden acceleration can demand too
much of those places. You can lose control.
What should
YOLI do if this ever happens‘? Ease up on the
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 it
curve. do it befhre you enter the curve, while your front
wheels are straight ahead.
Try

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.
3- 10

Downloaded from www.Manualslib.com manuals search engine 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.
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 accelerationj 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.

Driving Across an Incline
Sooner or later, an off-road trail will probably go across
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.

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 31 incline. Just because the trail goes
;lcross the incline doesn’t mean you have to drive it. The
last vehcle
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
b *et 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
came you to slide
out
of control.
I A CAUTION:
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.
Driving in Water
Light rain causes no special off-road driving problems.
But heavy rain can mean tlash 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.
4-26

Downloaded from www.Manualslib.com manuals search engine 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
b 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.
I 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.

information on driving throwh water.
After Off-Road Driving
Remove any brush or debris that has collected on the
underbody, chassis or under the hood. These
accumulations can be
