You may never need
4 LOW. It sends the maximum power to all four wheels.
You might choose
4 LOW if you were driving off-road in sand, mud, or deep
snow and climbing or descending steep hills.
You can shift from
2 WHEEL to 4 HIGH or from 4 HIGH to 2 WHEEL while
the vehicle is moving.
It is not necessary for you to press the transfer case
shift lever button. Your front axle will engage faster if you take your foot
off
of the accelerator for a few seconds after you shift.
To shift into or out of 4 LOW or N SET PARKING BRAKE:
-
1. Stop your vehicle and shift your transmission into neutral.
2. Press the transfer case shift button and shift in one continuous motion.
Don’t pause in
N SET PARKING BRAKE as you shift into or out of 4 LOW,
or your gears could clash.
Remember that driving in
4 HIGH or 4 LOW 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.
Electronic Transfer Case

The optional electronic shift transfer case switch is on the left side of your
instrument panel above the light switches. Use this switch to \
shift into and
out of four-wheel drive. You can choose among three driving settings:

street and highway situations. Your front axle
is not engaged in
two-wheel drive.

Control of a Vehicle
AM409005
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 thr\
ee 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 e\
asy
to ask more of
those control systems than the tires and road can provide. Tha\
t means you
can lose control
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
314 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, coordinati\
on, 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 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 t\
he road (wet,
dry,
icy); tire tread; and the condition of your brakes.

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 sudd\
enly apply the
brakes. Both control systems-steering and braking-have to do their work
where the tires meet the road. Adding the hard braking can de\
mand too
much at those places. You can lose control. The same thing can happen
if
you’re steering through a sharp curve and you suddenly accel\
erate. 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? Let 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.
When you drive into a curve at night, it’s harder to see the road ahead of
you because it bends away from the straight beams of your lights. This is
one
good reason to drive slower.
Steering in Emergencies
There are times when steering can be more effective than braki\
ng. For
example, you come over a hill and find a truck stopped in your lane, or a

Don’t overtake a slowly moving vehicle too rapidly. Even tho\
ugh the
brake lights are not flashing, it may be slowing down or starting to turn.
If you’re being passed, make it easy for the following driv\
er 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 whe\
n the three
control systems (brakes, steering and acceleration) don’t ha\
ve 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 conditi\
ons, and by not
“overdriving” those conditions. But skids are always possib\
le.
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 (as when you turn
a corner on a wet, snow- or ice-covered road), ease your foo\
t
off the
accelerator pedal as soon as you feel the tires start to slide. Quickly steer
the way you want the vehicle to go. If you start steering quickly enough, your
vehicle will straighten out.
As it does, straighten the front wheels.
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 limit\
ed.
While driving on a surface with reduced traction, try your bes\
t to avoid
sudden steering, acceleration, or braking (including engine brak\
ing by shifting
to a lower gear). Any sudden move 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.

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 v\
ehicle. If something
happens to one of them, the other can help quickly.
Does your vehicle have a winch? If
so, be sure to read the winch
instructions. In a remote area, a winch can be handy
if you get stuck. But
you’ll want to know how to use
it properly.
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, hand\
s, feet, and
body you’ll need to respond
to vibrations and vehicle bounce.

Downloaded from www.Manualslib.com manuals search engine 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 acro\
ss the incline.
Here are some things to consider:
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 dist\
ance
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 r\
ollover.
Surface conditions can be a problem when you drive across a h\
ill. 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 mor\
e.
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.
CAUTION
Driving across an incline that’s too steep will make your vehicle roll
over. Yolu could ble seriously injured or killed. If you h’ave any doubt
about the steepness of the incline, don’t drive
across it. Find another
route instead.
Q: What if I’m driving across an incline that’s not too steep, but I hit
some loose gravel and start to slide downhill. What should
I do?
A: If you feel your vehicle starting to slide sideways, turn downhill. This
should help straighten out the vehicle and prevent the side sl\
ipping. However,
a much better .way to prevent this
is to get out and “walk the course” so you
know what the surface is like before you drive
it.

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 tract\
ion
is so poor
that you will have difficulty accelerating. And
if you do get moving, poor

Driving In Water
Light rain causes no special off-road driving problems. But hea\
vy 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. S\
talling can also
occur
if you get your tailpipe under water. And, as long as your tailp\
ipe is
under water, you’ll never be able to start your engine. Whe\
n you go through
water, remember that when your brakes get wet,
it may take you longer to
stop.
A
Driving through rushing water can be dangerous. Deep water can
sweep your vehilcle downstream and you and your passengers could
drown.
If it’s only inches deep, 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.

After Off-Road Driving
Remove any brush or debris that has collected on the underbodv\
. chassis, or
under the hood. These accumulations can be a fire hazard.
After operation in mud or sand, have the brake linings cleaned\
and checked.
These substances can cause glazing and uneven braking. Check th\
e body
structure, steering, suspension, wheels, tires, and exhaust syste\
m for damage.
Also, check the fuel lines and cooling system for any leakage.\

Your vehicle will require more frequent service due to off-road use.\
Refer to
the Maintenance Schedule for additional information.
Driving at Night
AN450005
Night driving is more dangerous than day driving. One reason is that some
drivers are likely
to be impaired-by alcohol or drugs, with night vision
problems, or by fatigue.
Here are some tips on night driving.
Drive defensively. Remember, this is the most dangerous time.
Don’t drink and drive (See “Drunken Driving” in the Index for more on
this problem.)
Adjust your inside rearview mirror to reduce the glare from headlights
behind you.
