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.
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.
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 kmh) 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; and the condition
of your brakes.

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 wark at all times
-- whether you are
in two-wheel drive or four-wheel drive.
Braking in Emergencies
Use your anti-lock braking system when you need to.
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 eftort.
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.

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 you
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 roadconditions. 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.
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 petform 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.
4-9

Downloaded from www.Manualslib.com manuals search engine 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 wheel once
you have
avoided the object.
The fact that such emergency situations are always
possible
is a good reason to practice defensive driving at
all times and wear safety belts properly.
Off-Road Recovery
You m find sometime that your right wheels have
droppe
1 off the edge of a road onto the shoulder while
you’re ,Iriving.
If the level of the shoulder is only slightly below the
pavement, recovery should be fairly easy. Ease
off the
accelerator and then, if there is nothing
in the way, steer so
that your vehicle straddles the edge of the pavement. You
can
turn the steering wheel up to one-quarter turn until the
right front tire contacts the pavement edge. Then
turn your
steering wheel to
go straight down the roadway.

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

if
your right outside mirror is convex, the vehicle you
just passed may seem to be ,farther away from you
than it really is.)
on two-lane roads. Reconsider before passing the
next vehicle.
Try not to pass more than one vehicle at a time
0 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.
4-12

Downloaded from www.Manualslib.com manuals search engine 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.
Remember: Any anti-lock brake system (ABS) helps
avoid only the braking skid.
Driving Guidelines
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 two-wheel-drive vehicles any more than
low-slung sports cars
are designed to perform
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.

Off-road driving can take you over many different kinds of terrain. You need to be familiar with
the terrain and its
many different features. Here are some things to consider.
Surfiuce Conditions. Off-roading can take you over
hard-packed
dirt, gravel, rocks, grass, sand, mud, snow or
ice. Each of these surfaces affectsthe 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.
&$ace Obstacles. 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?
0 Does the travel take you uphill or downhill?
0 Will you have to stop suddenly or change
(There’s more
discussion
of these subjects later.)
direction quickly? When
you drive over obstacles or
rough terrain, keep a
firm grip on the steering wheel. Ruts, troughs or other
surface 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.

Once you decide you can safely drive up the hill, you
need to take some special steps.
Use a low 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 wheels 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.
7 - ~~
A CAUTION:
Turning or driving across steep hills can be
dangerous.
You could lose traction, slide
sideways, and possibly roll over.
You could be
seriously injured or killed. When driving up hills,
always try to go straight up.
Ease up on your speed as you approach the top
of the hill.
Attach a flag to the vehicle to make you more visible
to approaching traffic on trails or hills.
Sound the horn as you approach the top of the hill to
let opposing traffic know you’re there.
Use your headlamps even during the day. They make
you more visible to oncoming traffic.
A CAUTION:
Driving to the top (crest) of a hill at full speed can
cause an accident. There could be a drop-off,
embankment, cliff, or even another vehicle.
You
could be seriously injured or killed. As you near
the top of a hill, slow down and stay alert.
