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.
I 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 314 of a second, a vehicle
moving at
60 mph ( 100 km/h) 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; the condition
of your brakes; the weight of the
vehicle and the amount
of brake force applied.

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
* ‘.s is normal.
Braking in Emergencies
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 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 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 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.
4-9

Downloaded from www.Manualslib.com manuals search engine 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 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. (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.
4-10

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 one-quarter turn until the
right front tire contacts the pavement edge. Then turn your
steering wheel
to go straight down the roadway.

Downloaded from www.Manualslib.com manuals search engine 0 Check your mirrors, glance over your shoulder and
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
and move back
into the right lane. (Remember that
your right outside mirror is convex. The vehicle
you
just passed may seem to be farther away from you
than
it really is.)
0 Try not to pass more than one vehicle at a time on
two-lane roads. Reconsider before passing the
next vehicle.
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.
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.
4-13

Downloaded from www.Manualslib.com manuals search engine A cornering skid and an acceleration slud 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.
Remember: Any anti-lock brake system (ABS) helps
avoid only the braking skid.
Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to be
impaired
-- by alcohol or drugs, with night vision
problems, or by fatigue.

What’s the worst time for this? “Wet ice.” Very cold
snow or
ice can be slick and hard to drive on. But wet
ice can be even more trouble because it may offer the
least traction of all.
You can get wet ice when it’s about
freezing
(32°F; OOC) and freezing rain begins to fall.
Try to avoid driving on wet ice until salt and sand crews
can get there. Whatever the condition
-- smooth ice, packed, blowing
or loose snow -- drive with caution.
Accelerate gently.
Try not to break the fragile traction. If
you accelerate too fast, the drive wheels will spin and
polish the surface under the tires even more.
Your anti-lock brakes improve
your vehicle’s stability
when
you make a hard stop on a slippery road. Even
though you have an anti-lock braking system, you’ll
want to begin stopping sooner than
you would on dry
pavement. See “Anti-Lock” in the Index.
a
a
Allow greater following distance on any
slippery road.
Watch for slippery spots. The road might be fine
until you hit a spot that’s covered with ice. On an
otherwise clear road,
ice patches may appear in
shaded areas where the sun can’t reach: around
clumps
of trees, behind buildings or under bridges.
Sometimes the surface of a curve or
an overpass may
remain icy when the surrounding roads are clear. If
you see a patch of ice ahead of you, brake before you
are on it. Try not to brake while you’re actually on
the ice, and avoid sudden steering maneuvers.
4-25

Downloaded from www.Manualslib.com manuals search engine Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want
to get
to know your rig. Acquaint yourself with the feel
of
handling and braking with the added weight of the
trailer. And always keep in mind that the vehicle
you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before
you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand to be sure
the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally
to be sure that the
load is secure, and that the lamps and any trailer brakes
are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as you
would when driving your vehicle without a trailer. This
can help
you avoid situations that require heavy braking
and sudden turns.
Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re
a good deal
longer, you’ll need
to go much farther beyond the
passed vehicle before
you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the left. To move the trailer to the right, move your
hand
to the right. Always back up slowly and, if
possible, have someone guide
you.
Making Turns
NOTICE:
Making very sharp turns while trailering could
cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you’re turning with a trailer, make wider turns than
normal. Do this so your trailer won’t strike soft shoulders,
curbs, road signs, trees or other objects. Avoid jerky or
sudden maneuvers. Signal well in advance.

The hazard warning flasher button is located on top of
the steering column.
Your hazard warning flashers let you warn others. They
also
let police know you have a problem. Your front and
rear turn signal lamps will flash on and
off.
Press the button down to make your front and rear turn
signal lamps flash on and
off. Your hazard warning
flashers work
no matter what position your key is in,
and even if the key isn’t in.
To turn off the flashers, press the button down again.
When the hazard warning flashers are on. your
turn signals
won’t work. They
also won’t flash while you’re braking.
