Downloaded from www.Manualslib.com manuals search engine 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.

Downloaded from www.Manualslib.com manuals search engine 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 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; and the condition of your brakes.
Avoid needless heavy braking. Some people drive in spurts
- heavy
acceleration followed by heavy braking
- rather than keeping pace with
traffic. This is a mistake. Your brakes may not have time to cool between
hard stops. Your brakes will wear out much faster if you do a lot
of heavy
braking. If you keep pace with the traffic and allow realistic following
distances, you will eliminate a lot of unnecessary braking. That means better
braking and longer brake
life.
If your engine ever stops while you’re driving, brake normally but don’t
pump your brakes. If you do, the pedal may get harder to push down. If
your engine stops, you will still have some power brake assist. But you will
use it when you brake. Once the power assist is used up, it may take longer
to stop and the brake pedal will be harder to push.

Your vehicle has an advanced electronic braking system that can help you
keep it under control. When you start your vehicle and begin to drive away,
you may hear a momentary motor or clicking noise. This is the ABS system
testing itself.
nere
s now anti-lock works. Let’s say the road is wet. You’re driving safely.
Suddenly an animal jumps out
in front of you.
You slam on the brakes. Here’s 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
front wheel and at
the rear wheels. 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. You can steer around
the obstacle while braking hard.
As you brake, your computer keeps receiving updates on wheel speed and
controls braking pressure accordingly.

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. 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.
To Use 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.
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.
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.
4-7

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. 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.

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’s 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.
Do not get too close to the vehicle you want to pass while you’re
awaiting
an opportunity. For one thing, following too closely reduces
your
area of vision, especially if you’re following a larger vehicle.
Also, you won’t have adequate space if the vehicle ahead suddenly
slows or stops. Keep back a reasonable distance.
When it looks like a chance
to pass is coming up, start to accelerate but
stay in the right lane and don’t get too close. Time your move
so you
will be increasing speed as the time comes to move into the other lane.
If the way is clear to pass, you will have a “running start” that more
than makes up for the distance you would lose by dropping back. And
if something happens
to cause you to cancel your pass, you need only
slow down and drop back again and wait for another opportunity.
If other cars are lined up to pass a slow vehicle, wait your turn. But
take care that someone isn’t trying to pass
you as you pull out to pass
the slow vehicle. Remember
to glance over your shoulder and check
the blind spot.
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.)
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 lights 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. Perham vou
can ease a little to the ripht.

Downloaded from www.Manualslib.com manuals search engine Loss of Confrol
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.
Remember: Any anti-lock brake system (ABS) helps avoid only the braking
skid.

windshield washer tank filled. Replace your windshield wiper inserts when
they show signs
of streaking or missing areas on the windshield, or when
strips of rubber start to separate from the inserts.
Driving too fast through large water puddles or even going through some
car washes can cause problems, too. The water may affect your brakes. Try
to avoid puddles. But if you can’t, try to slow down before you hit them.
I A CAUTION: .’
Wet brakes can cause accidents. They won’t work well in a
quick stop and may cause pulling to one side.
You could lose
control of the vehicle.
After driving through a large puddle
of water or a car wash,
apply your brake pedal lightly until your brakes work normally.\

Hydroplaning
Hydroplaning is dangerous. So much water can build up under your tires
that they can actually ride on the water. This can happen if the road
is wet
enough and you’re going fast enough. When your vehicle is hydroplaning, it
has little or no contact with the road.
Hydroplaning doesn’t happen often. But it can if your tires haven’t much
tread or if the pressure in one or more is low. It can happen if a lot
of water
is standing on the road. If
you can see reflections from trees, telephone
poles, or other vehicles, and raindrops “dimple” the water’s surface; there
could be hydroplaning.
Hydroplaning usually happens at higher speeds. There just
isn’t a hard and
fast rule about hydroplaning. The best advice is to slow down when it is
raininq.

Downloaded from www.Manualslib.com manuals search engine Your anti-lock brakes improve your ability to 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.
0 Allow greater following distance on any slippery road.
0 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.

If you are stopped by heavy snow, you could be in a serious situation. You
should probably stay with your vehicle unless you know for sure that you
are near help and you can hike through the snow. Here are some things
to do
to summon help and keep yourself and your passengers safe: Turn on your
hazard flashers. Tie a red cloth to your vehicle to alert police that you've
been stopped by the snow. Put on extra clothing or wrap
a blanket around
you. If you have no blankets or extra clothing, make body insulators from
newspapers, burlap bags, rags, floor mats
- anything you can wrap around
yourself or tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
