amount of coffee or number of cold showers will speed that up. “I’ll be
careful” isn’t the right answer. What if there’s an emergency, a need to take
sudden action, as when a child darts into the street?
A person with even a
moderate
BAC might not be able to react quickly enough to avoid the
collision.
There’s something else about drinking and driving that many people don’t
know. Medical research shows that alcohol
in a person’s system can make
crash injuries worse, especially injuries
to the brain, spinal cord or heart.
This means that when anyone who has been drinking
- driver or passenger
- is in a crash, that person’s chance of being killed or permanently disabled
is higher than if the person had not been drinking.
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.

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.
To Use Rear- Wheel Anii-Lock
Use rear-wheel anti-lock like regular brakes. You may feel the brakes
vibrate, or
you may notice some noise outside your vehicle, but this is
normal. Let anti-lock work for you, but remember: Your front wheels can
still stop rolling. If that happens, release enough pressure
on the brakes to
get the wheels rolling again
so that you can steer.
Braking in Emergencies
At some time, nearly every driver gets into a situation that requires hard braking.
The four-wheel anti-lock system
lets you steer and brake at the same time.
If you have the rear-wheel anti-lock braking system, your front wheels can
stop rolling when you brake very hard. Once they do, the vehicle can’t
respond to your steering. Momentum will carry
it in whatever direction it
was headed when the front wheels stopped rolling. That could be off the
road, into the very thing you were trying
to avoid, or into traffic.
So, unless you have four-wheel anti-lock, use a “squeeze” braking
technique. This will give
you maximum braking while maintaining steering
control. You do this by pushing on the brake pedal with steadily increasing
pressure. When you do, it
will help maintain steering control. 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
4-7
Downloaded from www.Manualslib.com manuals search engine 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 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’re 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.
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’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 perform very well in emergencies like these. First apply
your brakes
- but, unless you have four-wheel anti-lock, not enough to
lock your front wheels.
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.
4-8
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 may find sometime 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 114 turn until the right front tire contacts
the pavement edge. Then turn your steering wheel to go straight down the
roadway.

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.
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.
4- 11
Downloaded from www.Manualslib.com manuals search engine Remember: If you have the four-wheel anti-lock braking system, it helps
avoid only the braking skid. The rear-wheel anti-lock braking system helps
avoid only a rear braking skid. In a braking skid (where the front wheels are
no longer rolling), release enough pressure
on the brakes to get the front
wheels rolling again. This restores steering control. Push the brake pedal
down steadily when you have to stop suddenly. As long as the front wheels
are rolling, you will have steering control.
Driving Guidelines
OR-Road 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 are 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. Check to make sure all
underbody shields (if
so equipped) are properly attached. 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.

Downloaded from www.Manualslib.com manuals search engine 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, hands, feet, and
body you’ll need to respond to vibrations and vehicle bounce.
Controlling your vehicle is the key to successful off-road driving. One
of
the best ways to control your vehicle is to control your speed. Here are some
things to keep in mind.
At higher speeds:
you approach things faster and you have less time to scan the terrain for
obstacles.
you have less time to react.
you have more vehicle bounce when you drive over obstacles.
you’ll need more distance for braking, especially since you’re on an
unpaved surface.
Scanning the Terrain
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.
Sugace Conditions. Off-roading can take you over hard-packed dirt,
gravel, rocks, grass, sand, mud, snow or ice. Each of these surfaces affects
the 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.
4- 14
Downloaded from www.Manualslib.com manuals search engine Sur$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:
Is the path ahead clear?
0 Will the surface texture change abruptly up ahead?
0 Does the travel take you uphill or downhill? (There’s more discussion
of these subjects later.)
0 Will you have to stop suddenly or change 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.)
Driving On Off-Road Hills
Off-road driving often takes you up, down, or across a hill. Driving safely
on hills requires good judgment and an understanding of what your vehicle
can and can’t do. There are some hills that simply can’t be driven, no matter
how well built the vehicle.
