Luggage Carrier (Option)
The luggage carrier has slats and side rails attached to the roof, and cross
rails which can be moved fore and aft in the side rails to help secure cargo.
Tie the load
to the side rails or side rail supports. Use the cross rails mostly
for fore and aft stops.
NOTICE:
Loading cargo that weighs more than 200 pounds (90.6 kg) on
the luggage carrier may damage your vehicle. When you carry
large things, never let them hang over the rear or the sides of
your vehicle. Load your cargo
so that it rests on the slats and
does not scratch or damage the vehicle. Put the cargo against the
side rails and fasten
it securely to the luggage carrier.
Don’t exceed the maximum vehicle capacity when loading your vehicle. For
more information on vehicle capacity and loading, see “Loading Your
Vehicle” in the Index.
To prevent damage or loss of cargo as you’re driving, check now and then to
make sure the luggage carrier and cargo are still securely fastened.
Be sure the cargo is properly loaded.
0 If small heavy objects are placed on the roof, place the load in the area
over the rear wheels (behind the rear side door
on wagon models). If
you need to, cut a piece of 3/8 inch plywood to fit inside the cross rails
and side rails to spread the load.
If plywood is used, tie it to the side rail
supports.
0 Tie the load to the cross rails or the side rail supports. Use the cross
rails only
to keep the load from sliding.

If you need to carry long items, move the cross rails as far apart as they
will go. Tie the load to the cross rails and the side rails or side rail
supports. Also tie
the load to the bumpers. Do not tie the load so tightly
that the cross rails or side rails are damaged.
After moving the cross rails, be sure to tighten all the slider screws.
Trailer Wiring Harness (Option)
An optional 7-wire
harness
is stored under
your vehicle along the
rear frame

harness has a

in-line fused battery
feed wire and no
connector, and should
be wired by a
qualified electrical
technician.
Securely attach the harness
to the trailer, then tape or strap it to your
vehicle’s frame rail. Be sure
you leave it loose enough so the wiring won‘t
bind or break when turning with the trailer, but
not so loose that it drags on
the ground.
Store the harness in its original position. Wrap the harness together and tie it
neatly so it won’t be damaged.

Off-Road Driving with Your
Four- Wheel Drive Vehicle
This off-road guide is for vehicles that have four-wheel drive.
Also, see “Anti-lock Brakes”
in the Index.
If your vehicle doesn’t have four-wheel drive, you shouldn’t drive off-road
unless you’re
on a level, solid surface.
Off-road driving
can be great fun. But it does have some definite hazards.
The greatest of these is the terrain itself.
“Off-roading” means you’ve left the great North American road system
behind. Traffic lanes aren’t marked. Curves aren’t banked. There are no
road signs. Surfaces can be slippery, rough, uphill or downhill. In short,
you’ve gone right back
to nature.
Off-road driving involves some new skills. And that’s
why it’s very
important that you read this guide. You’ll find many driving tips and
suggestions. These will help make your off-road driving safer and more
enjoyable.
Before You Go Off-Roading
There are some things to do before you go out. For example, be sure to have
all necessary maintenance and service work done. Be sure you read
all the
information about your four-wheel drive vehicle
in this manual. Is there
enough fuel?
Is the spare tire fully inflated? Are the fluid levels up where
they should be? What are the local laws that apply to off-roading where
you’ll be driving? If you don’t know, you should check
with law
enforcement people in the area. Will you be on someone’s private land? If
so, be sure to get the necessary permission.
Loading Your Vehicle for Off-Road Driving
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

Winter Driving
Here are some tips for winter driving:
0 Have your vehicle in good shape for winter. Be sure your engine
coolant
mix is correct.
0 You may want to put winter emergency supplies in your vehicle.
Include an ice scraper, a small brush or broom, a supply
of windshield
washer fluid, a rag, some winter outer clothing, a small shovel, 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.

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 and sudden turns.
Passing
You’ll need more passing distance up ahead when you’re towing a trailer.
And, because you’re a good deal longer, you’ll need
to go 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.
