Your Driving, the Road, and
Your Vehicle
Whenever we drive, we are taking on an
important responsibility. This is true for any motor
vehicle — passenger car, van, truck, sport utility.
Driver behavior, the driving environment, and the
vehicle’s design all affect how well a vehicle performs.
But statistics show that the most important factor,
by far, is how we drive.
Knowing how these three factors work together can
help you understand how your vehicle handles and
what you can do to avoid many types of crashes,
including a rollover crash.
Driver Behavior
The single most important thing is this: everyone in
the vehicle, including the driver, should buckle up.
SeeSafety Belts: They Are for Everyone on page 1-10.
In fact, most serious injuries and fatalities to unbelted
occupants can be reduced or prevented by the use
of safety belts. In a rollover crash, an unbelted person
is signicantly more likely to die than a person wearing
a seat belt. In addition, avoiding excessive speed,
sudden or abrupt turns, and drunken or aggressive
driving can help make trips safer and avoid thepossibility of a crash, especially a rollover crash. This
section provides many useful tips to help you drive
more safely.
Driving Environment
You can also help avoid a rollover or other type of crash
by being prepared for driving in inclement weather, at
night, or during other times where visibility or traction
may be limited, such as on curves, slippery roads,
or hilly terrain. Unfamiliar surroundings can also have
hidden hazards.
To help you learn more about driving in different
conditions, this section contains information about city,
freeway, and off-road driving, as well as other hints
for driving in various weather conditions.
Vehicle Design
According to the U.S. Department of Transportation,
utility vehicles have a signicantly higher rollover
rate than other types of vehicles. Utility vehicles do
have higher ground clearance and a narrower track
or shorter wheelbase than passenger cars, to make
them more capable for off-road driving. Specic
design characteristics like these give the driver a
better view of the road, but also give utility vehicles a
higher center of gravity than other types of vehicles.

Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down. If
one of the wheels is about to stop rolling, the computer
will separately work the brakes at each wheel.The anti-lock system can change the brake
pressure faster than any driver could. The computer
is programmed to make the most of available tire and
road conditions. This can help you steer around the
obstacle while braking hard.
As you brake, your computer keeps receiving updates
on wheel speed and controls braking pressure
accordingly.

Remember: Anti-lock does not 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 will not 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
Do not pump the brakes. Just hold the brake pedal
down rmly and let anti-lock work for you. You may feel
a slight brake pedal pulsation or notice some noise,
but this is normal.
Braking in Emergencies
At some time, nearly every driver gets into a situation
that requires hard braking.
If you have anti-lock, you can steer and brake at the
same time. However, if you do not have anti-lock, your
rst reaction — to hit the brake pedal hard and hold
it down — may be the wrong thing to do. Your wheels
can stop rolling. Once they do, the vehicle can not
respond to your steering. Momentum will carry it
in whatever direction it was headed when the wheels
stopped rolling. That could be off the road, into the
very thing you were trying to avoid, or into traffic.If you do not have anti-lock, use a “squeeze” braking
technique. This will give you maximum braking while
maintaining steering control. You can do this by pushing
on the brake pedal with steadily increasing pressure.
In an emergency, you will probably want to squeeze
the brakes hard without locking the wheels. If you hear
or feel the wheels sliding, ease off the brake pedal.
This will help you retain steering control. If youdohave
anti-lock, it is different. See “Anti-Lock Brake System”
in this section.
In many emergencies, steering can help you more than
even the very best braking.
Traction Control System (TCS)
Your vehicle may have a traction control system that
limits wheel spin. This is especially useful in slippery
road conditions. The system operates only if it senses
that one or both of the front wheels are spinning or
beginning to lose traction. When this happens,
the system reduces engine power to limit wheel spin.
4-10
ProCarManuals.com

This light will come on
when your traction control
system is limiting wheel
spin. SeeLow Traction
Light on page 3-33.
You may feel or hear
the system working, but
this is normal.
The traction control system automatically comes
on whenever you start your vehicle. To limit wheel spin,
especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system off if you ever need to. You
should turn the system off if your vehicle ever gets stuck
in sand, mud, ice or snow and rocking the vehicle is
required. See “Rocking Your Vehicle To Get It Out”
underIf You Are Stuck: In Sand, Mud, Ice or Snow
on page 4-44.If your vehicle is equipped
with the 2.2L four cylinder
engine, the traction
control system can be
turned off by pressing the
traction control button.
It is located on the
instrument panel above
the audio system.
The light on the button will go off. If your vehicle is
equipped with the 3.5L V6 engine, the traction control
system will be turned off when the shift lever is in
REVERSE (R) or LOW (L). The traction control system
warning light will be displayed on the instrument
panel.
The traction control system can be activated again
by pressing the traction control button for the 2.2L
four cylinder engine, or by selecting DRIVE (D)
or INTERMEDIATE (I) for the 3.5L V6 engine.
4-11
ProCarManuals.com

If the system is limiting wheel spin when you press
the button, the light on the button will go off, but
the system will not turn off until there is no longer a
current need to limit wheel spin. You can turn the system
back on at any time by pressing the button again. The
light on the button should come on. If the light does
not come on, you may not have traction control and your
vehicle should be serviced at a retailer.
All-Wheel Drive (AWD) System
If your vehicle has all-wheel drive (AWD), the AWD
system operates automatically without any action
required by the driver. If the front drive wheels begin
to slip, the rear wheels will automatically begin to
drive the vehicle as required. There may be a slight
engagement noise during hard use but this is normal.
During heavy AWD applications, the engine torque
may be reduced to protect AWD system components.
If the vehicle is exposed to extended heavy AWD
usage, the AWD system will shut itself off to protect
the system from overheating. When the system
cools down, the AWD system will activate itself again
automatically; this cool-down can take up to 20 minutes
depending on outside temperature and vehicle use.
Steering
Electric Power Steering
If the engine stalls while you are driving, the power
steering assist system will continue to operate until
you are able to stop your vehicle. If you lose power
steering assist because the electric power steering
system is not functioning, you can steer, but it will take
more effort.
If you turn the steering wheel in either direction several
times until it stops, or hold the steering wheel in the
stopped position for an extended amount of time, you
may notice a reduced amount of power steering
assist. The normal amount of power steering assist
should return shortly after a few normal steering
movements.
The electric power steering system does not require
regular maintenance. If you suspect steering system
problems and/or the Service Vehicle Soon light comes
on, contact your retailer for service repairs.

Steering Tips
Driving on Curves
It is important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here is 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 is no traction,
inertia will keep the vehicle going in the same direction.
If you have ever tried to steer a vehicle on wet ice,
you will 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
are in a curve, speed is the one factor you can control.
Suppose you are 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 are 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. SeeTraction Control
System (TCS) on page 4-10.
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 will 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 nd
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 cannot; there is not room.
That is the time for evasive action — steering around
the problem.
Your vehicle can perform very well in emergencies like
these. First apply your brakes — but, unless you
have anti-lock, not enough to lock your wheels.
SeeBraking on page 4-7. 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 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 may nd that your right wheels have dropped off the
edge of a road onto the shoulder while you’re driving.
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.
Passing
The driver of a vehicle about to pass another on a
two-lane highway waits for just the right moment,
accelerates, moves around the vehicle ahead, then
goes back into the right lane again. A simple maneuver?
Not necessarily! Passing another vehicle on a two-lane
highway is a potentially dangerous move, since the
passing vehicle occupies the same lane as oncoming
traffic for several seconds. A miscalculation, an error in
judgment, or a brief surrender to frustration or anger
can suddenly put the passing driver face to face with the
worst of all traffic accidents — the head-on collision.
So here are some tips for passing:
Drive ahead. Look down the road, to the sides
and to crossroads for situations that might affect
your passing patterns. If you have any doubt
whatsoever about making a successful pass, wait
for a better time.
Watch for traffic signs, pavement markings and
lines. If you can see a sign up ahead that might
indicate a turn or an intersection, delay your pass.
A broken center line usually indicates it is all
right to pass, providing the road ahead is clear.
Never cross a solid line on your side of the lane or
a double solid line, even if the road seems empty
of approaching traffic.

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
are not 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 is best handled by easing your foot
off the accelerator pedal.
If you have the Traction Control System (TCS),
remember: It helps avoid only the acceleration skid.
SeeTraction Control System (TCS) on page 4-10.Ifyou
do not have this system, or if the system is off, then
an acceleration skid is also 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 will 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 (ABS),
remember: It helps avoid only the braking skid. If you
do not have ABS, 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.

Operating Your All-Wheel-Drive
Vehicle Off Paved Roads
This off-road guide is for vehicles that have all-wheel
drive. If your vehicle does not have all-wheel drive, you
should not drive off-road unless you are on a level,
solid surface.
Many of the same design features that help make
your vehicle responsive on paved roads during
poor weather conditions — features like all-wheel
drive — help make it much better suited for off-road
use. Its higher ground clearance also helps your vehicle
step over some off-road obstacles. But your vehicle
does not have features like special underbody shielding
and a transfer case low gear range, things that are
usually thought necessary for extended or severe
off-road service.
Also, seeBraking on page 4-7.
Off-road driving can be great fun. But it does have
some denite hazards. The greatest of these is
the terrain itself.
“Off-roading” means you have left the North American
road system behind. Traffic lanes are not marked.
Curves are not banked. There are no road signs.
Surfaces can be slippery, rough, uphill or downhill.
In short, you have gone right back to nature.Off-road driving involves some new skills. And that is
why it is very important that you read this guide. You
will nd 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. Is there enough fuel? Is
the spare tire fully inated? Are the uid levels up where
they should be? What are the local laws that apply to
off-roading where you will be driving? If you do not
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 oor 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 does not toss things around.
