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.
Average
reaction time is about 314 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; the condition of your brakes; the weight of the
vehicle and the amount of brake force applied.
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 tim.
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.

Downloaded from www.Manualslib.com manuals search engine 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.
Anti-Lock Brakes (ABS)
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
When you start your engine and begin
to drive away,
your anti-lock brake system will check itself. You may
hear a momentary motor or clicking noise while this test
is going on, and you may even notice that your brake
pedal moves a little. This is normal.
ABS
If there’s a problem with
the anti-lock brake system,
this warning light will stay on. See “Anti-Lock Brake
System Warning Light” in
the Index.

Downloaded from www.Manualslib.com manuals search engine Here’s how 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 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.
I
I
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.
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.

Downloaded from www.Manualslib.com manuals search engine Using Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down
firmly and let anti-lock work for you. You may hear the
anti-lock pump or motor operate, and feel the brake
pedal pulsate, but this
is normal.
Traction Control System
Your vehicle has 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 rear wheels are spinning or beginning
to lose traction. When this happens, the system brakes
the spinning wheel and/or reduces engine power to
limit wheel spin.
You may feel or hear the system working, but this is normal.
This warning light will
come on to let you know if
there’s a problem with your traction control system.
See “Traction Control System Warning Light” in the
Index. When this warning light is on, the system will
not
limit wheel spin. Adjust your driving accordingly. 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. See “Rocking Your
Vehicle” in the Index.)
To turn the system off, press the TCS
OFF button located
next to the radio on the
center console.
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.

Downloaded from www.Manualslib.com manuals search engine 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.
Speed Sensitive Steering (SSS)
This system varies the amount of steering effort in
relation to your vehicle speed. Steering is easier at a
lower speed for maneuvering and parking ease. As your
vehicle speed increases, the steering effort
also increases.
At highway speeds, the amount of steering effort
is
increased to provide manual-like steering for maximum
control and stability.
If your vehicle seems harder to steer
than normal when parking or driving slow, something
may be wrong with the speed sensitive steering system.
You will still have power steering, however, steering will
be stiffer than normal at low speeds.
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. Refer to
“Traction Control System” in the Index.
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.
4-10

Downloaded from www.Manualslib.com manuals search engine 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. 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.

Downloaded from www.Manualslib.com manuals search engine Off-Road Recovery Passing
You may find 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. 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:
0 “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.
0 Watch for traffk 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.

Downloaded from www.Manualslib.com manuals search engine 0 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.
0 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.)
on two-lane roads. Reconsider before passing the
next vehicle.
0 Try not to pass more than one vehicle at a time
0 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.
