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
accelerate. Those two control systems-steering and acceleration-ca\
n
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 accel\
erator peaal,
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
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 proble\
m.
Your vehicle can perform very well in emergencies like these. First \
apply your
brakes.
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.
An emergency like this requires close attention and a quick decision.
If you
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

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 d\
rivers avoid
most skids by taking reasonable care suited
to existing conditions, 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 foot off the
accelerator pedal as soon as you feel the vehicle 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 best to avoid
sudden steering, acceleration,
or braking (including engine braking by shifting
to a lower gear). Any sudden changes could cause the tires t\
o 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.
Remember: Any anti-lock braking system (ABS) helps avoid only the braking
skid. Steer the way you want
to go.

Driving Guidelines (Utility Models)
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 you to anticipate problems. They are not
designed for cornering at the same speeds as conventional 2-whe\
el drive
vehicles any more than low-slung sports cars are designed to p\
erform
satisfactorily under off-road conditions. If at
all possible, avoid sharp turns or
abrupt maneuvers.
As with other vehicles of this type, failure to operate this
vehicle correctly may result in
loss of control or vehicle rollover.
OffmRoad Driving with Your Four-Wheel
Drive Vehicle
This off-road guide is for vehicles that have four-wheel drive. (Also, see
“Anti-lock Brakes” in the Index.)
If your vehicle doesn’t have four-wheel drive,
you shouldn’t drive off-road unless you’re on
a level, solid surface.
Off-road driving can be great fun. But it does have some definite hazards.
The greatest of these is the terrain itself.
“Off-roading” means you’ve left the great North American road system behind.
Traffic lanes aren’t marked. Curves aren’t banked. There a\
re no road signs.
Surfaces can be slippery, rough, uphill
or downhill. In short, you’ve gone right
back to nature.
Off-road driving involves some new skills. And that’s why it’s very important
that you read this guide. You’ll find many driving tips and suggestions. These
will help make your off-road driving safer and more enjoyable.
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. 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.
rn CAUTION
m m
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. I
You’ll find other important information in this manual. See “Vehicle Loading”,
“Luggage Carrier” and “Tires” in the Index.
Traveling to Remote Areas
It makes sense to plan your trip, especially when going to a \
:emote 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.
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 befor\
e
you go into the wilderness. Off-road driving does require some \
new and
different driving skills. Here’s what
we mean.

Your Driving and the Road
Approaching a Hill
When you approach a hill, you need to decide if it’s one of those hills that’s
just too steep to climb, descend, or cross. Steepness can be hard to judge.
On a very small hill, for example, there may be a smooth, constant incline
with only a small change in elevation where you can easily se\
e all the way
to the top. On a large hill, the incline may get steeper as you near the top,
but you may not see this because the crest of the hill is hidden by bushes,
grass, or shrubs.
Here are some other things to consider as you approach a
hill.

Is there a constant incline, or does the hill get sharply steeper\
in
places?
Is there good traction on the hillside, or will the surface cause tire
slipping?
Is there a straight path up
or down the hill so you won’t have to make
turning maneuvers?
Are there obstructions
on the hill than can block your path (boulders,
trees, logs or ruts)?
What’s beyond the hill? Is there a cliff, an embankment, a drop-off, a
fence? Get out and walk the hill
if you don’t know. It’s the smart way to
find out.
Is the hill simply too rough? Steep hills often have ruts, gu\
llies, troughs
and exposed rocks because they are more susceptible to the eff\
ects of
erosion.

Once you decide you can safely drive up the hill, you need to take some
special steps.

Use a lower gear and get a firm grip on the steering wheel. \
Get a smooth start up the hill and try to maintain your speed. Don’t use
more power than you need, because you don’t want your wheel\
s to start
spinning or sliding.
Try to drive straight up the hill if at all possible. If the path twists and
turns, you might want to find another route.

Q: What should I do if my vehicle stalls, or is about to stall, and I can’t
make it up the hill?
A: If this happens, there are some things you should do, and there \
are some
things you must not do. First, here’s what you should do:
Push the brake pedal to stop the vehicle and keep it from rolling
backwards.
Also, apply the parking brake.
If your engine is still running, shift the transmission into reverse, release
the parking brake, and slowly back down the hill in reverse.
If your engine has stopped running, you’ll need to restart it. With the
brake pedal depressed and the parking brake still applied, shift the
transmission to
P (Park) (or, shift to N (Neutral) if your vehicle has a
manual transmission) and restart the engine. Then, shift
to reverse,
release the parking brake, and slowly back down the hill
in reverse.
As you are backing down the hill, put your left hand on the steering
wheel at the
12 o’clock position. This way, you’ll be able to tell if your
wheels are straight or turned to the left or right as you back down.

Your Driving and the Road
What you do in the daytime can also affect your night vision. For example, if
you spend the day in bright sunshine you are wise to wear sunglasses. Your
eyes will have less trouble adjusting to night.
But
if you’re driving, don’t wear sunglasses at night. They may \
cut down on
glare from headlights, but they also make a lot of things invisible that should
remain visible-such as parked cars, obstacles, pedestrians, or e\
ven trains
blocking railway crossings. You may want
to put on your sunglasses after you
have pulled into a brightly-lighted service or refreshment area. Eyes shielded
from that glare may adjust more quickly
to darkness back on the road. But
be sure
to remove your sunglasses before you leave the service area.
You can be temporarily blinded by approaching lights. It can take a second or
two, or even several seconds, for your eyes to readjust
to the dark. When
you are faced with severe glare (as from a driver who doesn’\
t lower the high beams, or a vehicle with misaimed headlights), slow down a li\
ttle. Avoid
staring directly into the approaching lights.
If there is a line of opposing
traffic, make occasional glances over the line of headlights
to make certain
that one
of the vehicles isn’t starting to move into your lane. Once you are
past the bright lights, give your eyes time to readjust before resuming speed.
High Beams
If the vehicle approaching you has its high beams on, signal by \
flicking yours
to high and then back to low beam. This is the usual signal to lower the
headlight beams. If the other driver still doesn’t lower the beams, resist the
temptation
to put your high beams on. This only makes two half-blinded
drivers.
On a freeway, use your high beams only in remote areas where you w\
on’t
impair approaching drivers. In some places, like cities, using \
high beams is
illegal.
When you follow another vehicle on a freeway or highway, use \
low beams.
True, most vehicles now have day-night mirrors that enable the \
driver to reduce glare. But outside mirrors are not
of this type and high beams from
behind can bother the driver ahead.
A Few More Night Driving Suggesiions
Keep your windshield and all the glass on your vehicle clean-inside and out.
Glare at night is made much worse by dirt
on the glass. Even the inside of
the glass can build up a film caused by dust. Tobacco smoke also makes
inside
glass surfaces very filmy and can be a vision hazard if it’s left there.
Dirty glass makes lights dazzle and flash more than clean glas\
s would,
making the pupils of your eyes contract repeatedly. You might even want

If there is no curb when you’re parking uphill, turn the wheel\
s to the right.
If there is no curb when you’re parking uphill on the left si\
de of a one-way
street, your wheels should be turned to the left.
Torque Lock (Automatic Transmission)
If you are parking on a hill and you don’t shift your transmi\
ssion into P
(Park) properly, the weight of the vehicle may put too much \
force on the
parking pawl in the transmission. You may find
it difficult to pull the shift lever
out of
P (Park). This is called “torque lock.” To prevent torque lock, always
be sure
to shift into P (Park) before you leave the driver’s seat. To find out
how, see “Shifting Into P (Park)” in the Index.
When
you are ready to drive, move the selector lever out of P (Park)
BEFORE you release the parking brake.
If “torque lock” does occur, you may need to have another vehicle push
yours
a little uphill to take some of the pressure from the transmission, so
you can pull the shift lever out of P (Park).
