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
firmly and let anti-lock work for you. You may feel a
slight brake pedal pulsation or notice some noise,
but this is normal.
Braking in Emergencies
At some time, nearly every driver gets into a situation
that requires hard braking.
If you have anti-lock, you can steer and brake at the
same time. However,
if you don’t have anti-lock,
your first reaction
- to hit the brake pedal hard
and hold it down
- mav be the wronq thina to do. Your
wheels can stop rolling. Once they do, the vehicle
can’t respond to your steering. Momentum will carry
it in whatever direction it was headed when the wheels
stopped rolling. That could be off the road, into the
very thing you were trying to avoid, or into traffic.
If you don’t have anti-lock, use a “squeeze” braking
technique. This will give you maximum braking while
maintaining steering control. You can do this by pushing
on the brake pedal with steadily increasing pressure.
In an emergency, you will probably want to squeeze
the brakes hard without locking the wheels. If you hear
or feel the wheels sliding, ease
off the brake pedal.
This will help you retain steering control.
If you do have
anti-lock, it’s different. See “Anti-Lock Brakes.”
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 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. See
Traction Control
System (TCS) on page
4- 10.
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.
See
Braking on page 4-6. 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

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 Passing
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:
You may
find that your right wheels have dropped off the
edge
of a road onto the shoulder while you’re driving.
e
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.
e
“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.
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.

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 is best handled by easing your foot
off
the accelerator pedal.
If you have the Traction Control System, remember:
It helps avoid only the acceleration skid.
If you do not
have this system, or
if the system is off, then an
acceleration skid is also 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.
If you have the anti-lock braking system, remember:
It helps avoid only the braking skid.
if you do not have
anti-lock, then in a braking skid (where the wheels
are no longer rolling), release enough pressure on the
brakes to get the wheels rolling again. This restores
steering control. Push the brake pedal down steadily
when you have to stop suddenly.
As long as the wheels
are rolling, you will have steering control.
4-1 6

Remember, unless you have anti-lock, if you brake
so hard that your wheels stop rolling, you’ll just slide.
Brake so your wheels always keep rolling and you can
still steer.
0 Whatever your braking system, 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’re Caught in a Blizzard
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.

Notice: Spinning your wheels can destroy parts
of your vehicle as well
as the tires. If you spin the
wheels too fast while shifting your transaxle
back and forth, you can destroy your transaxle.
See “Rocking Your Vehicle
To Get It Out.”
For information about using tire chains on your vehicle,
see
Tire Chains on page 5-67.
Rocking Your Vehicle To Get It Out
First, turn your steering wheel left and right. That will
clear the area around your front wheels.
If your vehicle
has traction control, you should turn your traction
control system
off. See Traction Control System (TCS)
on page 4-10.
Then shift back and forth between
REVERSE (R) and a forward gear, spinning the wheels
as little as possible. Release the accelerator pedal
while you shift, and press lightly on the accelerator pedal
when the transaxle
is in gear. By slowly spinning your
wheels in the forward and reverse directions, you
will cause a rocking motion that may free your vehicle.
If that doesn’t get you out after a few tries, you may
need to be towed out. If you do need to be towed out,
see “Towing Your Vehicle” following.
