Sun Visors
To block out glare, you can swing down the
visors. You can also swing them out to block glare
from the side.
Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an
elaborate break-in. But it will perform better in
the long run if you follow these guidelines:
Let your engine warm up before you
operate your vehicle under load.
Keep your speed at 55 mph (88 km/h) or
less for the rst 500 miles (805 km).
Do not drive at any one speed, fast or
slow, for the rst 500 miles (805 km).
Do not make full-throttle starts.
Avoid making hard stops for the rst
200 miles (322 km) or so. During this time
your new brake linings are not yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking-in guideline every time
you get new brake linings.
Use the lowest gear you can when you start
a loaded vehicle in motion and when going
up hills to avoid overloading the engine.
Check and adjust engine and transmission
uid levels often and be sure tires are
properly inated for the load you are
carrying.
If you have a Caterpillar®diesel engine, see
the Caterpillar®Diesel Engine Operation
and Maintenance Manual.

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 are driving on snow or
ice, it is 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
SeeBrake System Warning Light on page 169.
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake
pedal. That is perception time. Then you have to
bring up your foot and do it. That is reaction time.Average reaction time is about three-fourths of
a second. But that is 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 three-fourths 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 is
pavement or gravel; the condition of the road,
whether it is wet, dry or icy; tire tread; the condition
of the brakes; the weight of the vehicle; the
weight of the load; and the amount of brake
force applied.
210

To turn the system on
or off, press the traction
control button located
on the instrument panel.
If you used the TCS button to turn the system off,
the light in the top of the button will come on and
stay on. You can turn the TCS back on at any time
by pressing the button again; the light should go off.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.
On vehicles with hydraulic brakes, the power
steering and main hydraulic brake system both use
the power steering pump. SeeBraking on page 210.
Steering Tips
Driving on Curves
It is important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned
on the news happen on curves. Here is 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 is
no traction, inertia will keep the vehicle going in the
same direction. If you have ever tried to steer a
vehicle on wet ice, you will understand this.
217

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 are in a curve, speed is
the one factor you can control.
Suppose you are 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.
SeeTraction Control System (TCS) on page 216.
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 will 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 cannot; there is not room. That is the time for
evasive action — steering around the problem.
Your vehicle can perform very well in emergencies
like these. First apply your brakes.
SeeBraking on page 210. 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.

•When it looks like a chance to pass is coming
up, start to accelerate but stay in the right lane
and do not 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 is
not trying to pass you as you pull out to pass
the slow vehicle.
•Check your vehicle’s mirrors and start the 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 vehicle’s passenger side outside mirror,
activate the right lane change signal and move
back into the right lane. Remember that, if your
vehicle’s right outside mirror is convex, the
vehicle you just passed may seem to be further
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.
•Do not 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 are 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 us review what driving experts say about what
happens when the three control systems — brakes,
steering, and acceleration — do not have enough
friction where the tires meet the road to do what the
driver has asked.
In any emergency, do not give up. Keep trying to
steer and constantly seek an escape route or
area of less danger.
221

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 are not 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 (TCS),
remember: It helps avoid only the acceleration
skid. SeeTraction Control System (TCS) on
page 216. 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.Of course, traction is reduced when water, snow,
ice, gravel, or other material is on the road.
For safety, you will 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 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 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 Brake System (ABS),
remember: It helps avoid only the braking skid.
If you do not have ABS, 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.

Keep the windshield and all the glass on your
vehicle clean — inside and out. Glare at night is
made much worse by dirt on the glass. Even
the inside of the glass can build up a film caused
by dust. Dirty glass makes lights dazzle and
flash more than clean glass would, making the
pupils of your eyes contract repeatedly.
Remember that the headlamps light up far less of a
roadway when you are in a turn or curve. Keep your
eyes moving; that way, it is easier to pick out dimly
lighted objects. Just as the headlamps should be
checked regularly for proper aim, so should your
eyes be examined regularly. Some drivers suffer
from night blindness — the inability to see in dim
light — and are not even aware of it.Driving in Rain and on Wet Roads
Rain and wet roads can mean driving trouble. On a
wet road, you cannot stop, accelerate, or turn as
well because your tire-to-road traction is not as
good as on dry roads. And, if your tires do not have
much tread left, you will get even less traction. It is
always wise to go slower and be cautious if rain
starts to fall while you are driving. The surface may
get wet suddenly when your reflexes are tuned for
driving on dry pavement.
