Downloaded from www.Manualslib.com manuals search engine Loading Your Vehide for Off-Road Rriving
There are some important things to remember about how to load your
vehicle.
The heaviest things should be on the load floor and forward of your
rear axle. Put heavier items as
far forward as you cm.
Be sure the load is secured properly, so driving on the off-road terrain
doesn’t toss things around.
You’ll find other important information in this manual. See
“ Vehicle
Loading,” and “Tires” in the Index.
Traveling to Remote Areas
It makes sense to plan your trip, especially when going to a rem\
ote area.
Know the terrain and plan your route. You are much less likely to get bad
surprises. Get accurate maps of
trails and terrain. Try to learn of any
blocked or closed roads.
It’s also a good idea to travel with at least one other v\
ehicle.
If something
happens to one
of them, the other can help quickly.
Does your vehicle have a winch?
If so, be sure to read the winch
instructions. In a remote area, a winch can be handy
if you get stuck. But
you’ll want to know how to use
it properly.

mix is correct.
Include an ice scraper, a small brush or broom, a supply of windshield
washer fluid, a rag, some winter outer clothing, a small shove\
l,
a flashlight,
a red cloth, and a couple
of reflective warning triangles. And, if you will be
driving under severe conditions, include a small bag
of sand, a piece of old
carpet or a couple of burlap bags to help provide traction. Be sure you
properly secure these items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where your tires meet the road probably\
have
good traction.
However, if there is snow or ice between your tires and the road, you can
have a very slippery situation. You’ll have a lot less traction or “grip” and
will need to be very careful.

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.

the tires.
