Remove any brush or debris that has collected on the underbody, chassis or
under the hood. These accumulations can be a fire hazard.
After operation in mud or sand, have the brake linings cleaned and checked.
These substances can cause glazing and uneven braking. Check th\
e body structure, steering, suspension, wheels, tires, and exhaust syste\
m for
damage. Also, check the fuel lines and cooling system for any leakage.
Your vehicle will require more frequent service due to off-road use.\

Driving at Night

problems,
or by fatigue.
Here are some tips on night driving.
Drive defensively.

behind you.

Night Vision
No one can see as well at night as in the daytime. But as we get older these
differences increase. A 50-year4d driver may require at least twice as
much light to see the same thing at night as a 20-year-old.
What you do in the daytime can also affect your night vision.\
For example,
if you spend the day in bright sunshine you are wise to wear sunglasses.
Your eyes will have less trouble adjusting to night. But if you’re driving,
don’t wear sunglasses at night. They may cut down on glare \
from
headlights, but they also make a lot of things invisible.
You can be temporarily blinded by approaching lights. It can take a second
or two, or even several seconds, for your eyes to readjust to the dark. When
you are faced with severe glare (as from a driver who doesn’\
t lower the high
beam, or a vehicle with misaimed headlights), slow down a little. A\
void
staring directly into the approaching lights.
Keep your 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 your headlights light up far less of a roadway when you
are
in a turn or curve. Keep your eyes moving; that way, it’s \
easier to pick out
dimly lighted objects. Just as your headlights 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 aren’t
even aware of it.
Driving in the Rain
Rain and wet roads can mean driving trouble. On a wet road you can’t st\
op,
accelerate or
turn as well because your tire-to-road traction isn’t as good as
on dry roads. And, if your tires don’t have much tread left, you’ll get even

Downloaded from www.Manualslib.com manuals search engine Try to use the freeways that rim and crisscross most large cities. You’ll
save time and energy. (See the next part, “Freeway Driving.”)
0 Treat a green light as a warning signal. A traffic light is there because
the corner is busy enough to need it. When a light turns green, and just
before you start to move, check both ways for vehicles that have not
cleared
the intersection or may be running the red light.
Freeway Driving
Mile for mile, freeways (also called thruways, parkways, expressways,
tumplkes, or superhighways) are the safest
of all roads. But they have their
own special rules.
The most important advice on freeway driving is: Keep up with
traffic and
keep to the right. Drive at the
same speed most of the other drivers are
driving. Too-fast or too-slow driving breaks a smooth traffic flow. Treat the
left lane on a freeway as a passing lane.
At the entrance there is usually a ramp that leads to the freeway. If you have
a clear view of the freeway as you drive along the entrance ramp, you
should begin to check traffic. Try to determine where you expe\
ct to blend
with the flow. Try to merge into the gap at close to the prevailing s\
peed.
Switch on your turn signal, check your mirrors and glance over your
shoulder
as often as necessary. Try to blend smoothly with the traffic flow.
Once you are on the freeway, adjust
your speed to the posted limit or to the
prevailing rate
if it’s slower. Stay in the right lane unless you want to pass.
Before changing lanes, check your mirrors. Then use your turn signal.
Just before you leave the lane, glance quickly over your shoulder t\
o make
sure there isn’t another vehicle
in your “blind” spot.
4-29

Downloaded from www.Manualslib.com manuals search engine Once you are moving on the freeway, make certain you allow a reasonable
following distance. Expect to move slightly slower at night.
When you want to leave the freeway, move to the proper lane well in
advance. If you miss your exit do not, under any circumstances, stop and
back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed
is usually posted.
Reduce your speed according to your speedometer, not to your s\
ense of
motion. After driving for any distance at higher speeds, you may tend to
think you are going slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you must start when you’re
not fresh
- such as after a day’s work - don’t plan to make too many
miles that first part of the journey. Wear comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip?
If you keep it serviced and maintained,
it’s ready to go. If it needs service, have it done before starting out. Of
course, you’ll find experienced and able service experts in Vehicle
dealerships all across North America. They’ll be ready and w\
illing to help if
you need it.
Here are some things you can check before a trip:
Windshield Washer Fluid: Is the reservoir full? Are all windows clean
inside and outside?
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked all levels?
Lights: Are they all working? Are the lenses clean?
Tires: They are vitally important to a safe, trouble-free trip. Is th\
e tread
good enough for long-distance driving? Are the tires all inflated to the
recommended pressure?
Should you delay your trip a short time to avoid a major storm syst\
em?
Weather Forecasts: What’s the weather outlook along your route?
Maps: Do you have up-to-date maps?

Is there actually such a condition as “highway hypnosis”? Or is it just plain
falling asleep at the wheel? Call it highway hypnosis, lack of awareness, or
whatever.
There is something about an easy stretch of road with the same scenery,
along with the hum
of the tires on the road, the drone of the engine, and the
rush of the wind against the vehicle that can make you sleepy. Don’t let it
happen to you!
If it does, your vehicle can leave the road in less than a
second, and you could crash and be injured.

0 If you get sleepy, pull off the road into a rest, service, or parking area
and take a nap, get some exercise, or both. For safety, treat drowsiness

an emergency.
Hill and Mountain Roads
Driving on steep hills or mountains is different from driving in flat or
rolling terrain.
If you drive regularly in steep country,
or if you’re planning to visit there,
here are some tips that can make your trips safer and more enjoyable. (See
“Off-Road Driving” in the Index for information about driving off-road.)

brakes, tires, cooling system and transmission. These parts can \
work
hard on mountain roads.
Know how to go down hills. The most important thing to know is this:
let your engine do some of the slowing down. Shift to a lower gear
when you go down a steep or long hill.
Know how to go uphill. You may want to shift down to a lower gear.
The lower gears help cool your engine and transmission, and you ca\
n
climb the hill better.
Stay in your own lane when driving on two-lane roads in hills or
mountains. Don’t swing wide
or cut across the center of the road. Drive
at speeds that
let you stay in your own lane.
As you .go over the top of a hill, be alert. There could be something in
your lane, like a stalled
car or an accident.
You may see highway signs on mountains that warn of special
problems. Examples are long grades, passing or no-passing zones, a
falling- rocks area, or winding roads. Be alert to these and \
take
appropriate action.

Downloaded from www.Manualslib.com manuals search engine You can tow trailers to 2,000 pounds (900 kg) with a step bumper hitch, but
if your trailer tongue has a V-shaped foot, your bumper could be damaged
in sharp turns. Check the distance from the front edge of the foot to the
middle of the hitch ball socket.
If the distance is less than 12 inches, take the
foot
off the trailer tongue.
Safety Chains
You should always attach chains between your vehicle and your trail\
er.
Cross the safety chains under the tongue of the trailer
so that the tongue will
not drop
to the road if it becomes separated from the hitch. Instructions
about safety chains may be provided by the hitch manufacturer \
or by the
trailer manufacturer. Follow the manufacturer’s recommendation for
attaching safety chains. Always leave just enough slack
so you can turn with
your rig. And, never allow safety chains to drag
on the ground.
Trailer Brakes
If your trailer weighs more than 1,000 pounds (450 kg) loaded, then it needs
its own brakes
- and they must be adequate. Be sure to read and follow the
instructions for the trailer bE---:s
so you’ll be able to install, adjust and
maintain them properly.
Your trailer brakes system can tap into vehicle’s hydraulic brake system
except:
Don’t tap into your vehicle’s brake system if the trailer’s brake system will
use more than
0.02 cubic inch (0.3~~) of fluid from your vehicle’s master
cylinder. If it does, both braking systems won’t work well. You could even
lose your brakes.
Will the trailer parts take
3,000 psi (20 650 Pa) of pressure? If not, the
trailer brake system must not be used with your vehicle.
If everything checks out this far, then make the brake fluid tap at the port on
the master cylinder that sends fluid to the rear brakes. But don’t use copper
tubing for this.
If you do, it will bend and finally break off. Use steel brake
tubing.
Driving with a Trailer
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. Acquai\
nt 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
so responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform, safety chains,
electrical connector, lights, tires and mirror adjustment. If th\
e trailer has
electric brakes, start your vehicle and trailer moving and then\
apply the

Downloaded from www.Manualslib.com manuals search engine trailer brake controller by hand to be sure the brakes are working. This lets
you check your electricql connection at the same time.
During your trip, check occasionally to be sure that the load \
is secure, and
that the lights 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 apd sudden turns.
Passing
You’ll need more passing distance up ahead when you’re to\
wing a trailer.
And, because you’re a good deal longer, you’ll need to g\
o 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
When you’re turning with a trailer, make wider turns than n\
ormal. 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.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have a different \
turn signal
flasher and extra wiring. The green arrows on your instrument panel wi\
ll
flash whenever you signal a turn or lane change. Properly hooked up, the
trailer lights will also flash, telling other drivers you’re \
about
to turn,
change lanes or stop.
When towing a trailer, the green arrows on your instrument pan\
el will flash
€or
turns even if the bulbs on the trailer are burned out. Thus, you may think
drivers behind you are seeing your signal when they are not. It’s importan\
t
to check occasionally to be sure the trailer bulbs are still \
working.
