Defensive Driving
Defensive driving means “always
expect the unexpected.” The
rst step in driving defensively is to
wear your safety belt — See
Safety Belts: They Are for Everyone
on page 1-11.
{CAUTION
Assume that other road users
(pedestrians, bicyclists, and other
drivers) are going to be careless
and make mistakes. Anticipate
what they might do and be ready.
In addition:
Allow enough following
distance between you and
the driver in front of you.
Focus on the task of driving.
Driver distraction can cause
collisions resulting in injury or
possible death. These simple
defensive driving techniques could
save your life.
Drunk Driving
{CAUTION
Drinking and then driving is very
dangerous. Your reexes,
perceptions, attentiveness, and
judgment can be affected by even
a small amount of alcohol. You
can have a serious — or even
fatal — collision if you drive after
drinking. Do not drink and drive or
ride with a driver who has been
drinking. Ride home in a cab; or if
you are with a group, designate a
driver who will not drink.
Death and injury associated with
drinking and driving is a global
tragedy.
Alcohol affects four things that
anyone needs to drive a vehicle:
judgment, muscular coordination,
vision, and attentiveness.
4-2 Driving Your Vehicle

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. These
problems can be avoided by
braking — if you can stop in time.
But sometimes you cannot stop
in time because there is no room.
That is the time for evasive
action —steering around the
problem.
The vehicle can perform very well in
emergencies like these. First
apply the brakes. SeeBraking on
page 4-3. It is better to remove
as much speed as possible from a
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 holding the steering wheel at
the recommended 9 and 3 o’clock
positions, it can be turned 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
The vehicle’s right wheels can drop
off the edge of a road onto the
shoulder while 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 the vehicle straddles
the edge of the pavement.
Driving Your Vehicle 4-11

Of course, traction is reduced when
water, snow, ice, gravel, or other
material is on the road. For safety,
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 reducing
vehicle speed by shifting to a lower
gear. Any sudden changes could
cause the tires to slide. You may not
realize the surface is slippery until
the 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 Antilock Brake
System (ABS) helps avoid only the
braking skid.Off-Road Driving
The airbag system is designed to
work properly under a wide range
of conditions, including off-road
usage. Always wear your safety belt
and observe safe driving speeds,
especially on rough terrain.
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
reexes, 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.Off-roading can be great fun
but has some denite hazards. The
greatest of these is the terrain
itself. When off-road driving, traffic
lanes are not marked, curves are not
banked, and there are no road
signs. Surfaces can be slippery,
rough, uphill, or downhill.
Avoid sharp turns and abrupt
maneuvers. Failure to operate the
vehicle correctly off-road could result
in loss of vehicle control or vehicle
rollover.
Off-roading involves some new
skills. That is why it is very important
that you read these driving tips
and suggestions to help make
off-road driving safer and more
enjoyable.
Driving Your Vehicle 4-13

For mounds, washouts, loose
up-hill slopes, ditches, etc.
When wheel spin occurs as the
vehicle is moving, the driver may
notice a slight shaking or shuddering
of the vehicle. This should be
stopped as soon as possible to
prevent damage to vehicle
components. This is the indication
that a loss of traction is occurring on
this terrain. The operator should:
1. Reduce speed and apply
the brakes.
2. Assess the terrain properly and
adjust vehicle speed and gear
ranges accordingly: Four-Wheel
High position for higher speeds
and Four-Wheel-Low Lock
for more torque and lower
speeds. Transmission 1 (First)
gear is generally recommended.3. Apply slight pressure to the
brake when the shaking or
shuddering sensation is felt,
keeping the vehicle moving in a
controlled manner.
4. Be prepared to alternate between
braking and accelerating through
the adverse terrain.
Getting Familiar with Off-Road
Driving
It is a good idea to practice in an
area that is safe and close to home
before you go into the wilderness.
Off-roading requires some new
and different skills.
Tune your senses to different
kinds of signals. Your eyes need
to constantly sweep the terrain
for unexpected obstacles. Your ears
need to listen for unusual tire or
engine sounds. Use your arms,
hands, feet, and body to respond to
vibrations and vehicle bounce.Controlling the vehicle is the key to
successful off-road driving. One of
the best ways to control the
vehicle is to control the speed.
At higher speeds:
You approach things faster and
have less time to react.
There is less time to scan the
terrain for obstacles.
The vehicle has more bounce
when driving over obstacles.
More braking distance is needed,
especially on an unpaved surface.
{CAUTION
When you are driving off-road,
bouncing and quick changes in
direction can easily throw you
out of position. This could cause
you to lose control and crash.
So, whether you are driving
on or off the road, you and
your passengers should wear
safety belts.
