Understanding Radio Reception
FM Stereo
FM stereo will give you the best sound. But FM signals
will reach only about 10
to 40 miles ( 16 to 65 km). Tall
buildings or hills can interfere with FM signals, causing
the sound
to come and go.
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations
to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise if you ever get it.

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. Check to make sure all underbody
shields (if
so equipped) are properly attached. 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 rear axle. Put heavier items as far
forward as you can.’
Be’ sure the load is secured properly, so driving on
’ the off-road ten@ doesn’t toss things around. Cargo on the load floor
piled higher than
the seatbacks can be thrown forward
during
a sudden stop. You or your
passengers could be injured. Keep cargo
below the top of the seatbacks.
Unsecured cargo on the load floor can be
tossed about when driving over rough
terrain. You or your passengers can be
struck by flying objects. Secure the
cargo properly.
Heavy loads on the roof raise the vehicle’s
center of gravity, making it more likely to
roll over.
You can be seriously or fatally
injured if the vehicle rolls over. Put heavy
loads inside the cargo area, not on the roof. Keep cargo in the cargo area
as far forward
and low
as possible.
You’ll find other important information
in this manual.

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.
Here are some tips for winter driving:
0 Have your vehicle in good shape for winter.
0 You may want to put winter emergency supplies in

The CertificatiodTire label is found on the driver's door
edge, above
the door latch. The label shows the size of
your original tires and the inflation pressures needed to
obtain the gross weight capacity of your vehicle. This is
called the GVWR (Gross Vehicle Weight Rating). The
GVWR includes the weight
of the vehicle, all occupants,
fuel, cargo and trailer tongue weight, if pulling a trailer.
The Certificationmire label also
tells you the maximum
weights for the front and rear axles, called Gross Axle
Weight Rating (GAWR). To find out the actual loads
on
your front and rear axles, you need to go to a weigh station and weigh your vehicle.
Your dealer can help
you with this. Be sure'to spread out your load equally
on both sides of the centerline.
Never exceed the GVWR for your vehicle, or
the
Gross Axle Weight Rating (GAWR) for either the front
or rear axle.
And, if you do have a heavy load, you should spread
it out.
Similar appearing vehicles may have different GVWR's
and payloads. Please note the Certificationire label
of
your truck or consult your dealer for additional details.

Downloaded from www.Manualslib.com manuals search engine ’ A CAUTIGA:
Do not load your vehicle any heavier than the
GVWR, or either the maximum front or rear
GAWR.
If you do, parts on your vehicle can
break, or it can change the
way your vehicle
handles. These could cause you to lose control.
Also, overloading can shorten the life of
your vehicle.
Using heavier suspension components to get added
durability might
not change your weight ratings. Ask
your dealer
to help you load your vehicle the right way.
NOTICE:
Your warranty does not cover parts or
components that fail because
of overloading. If
you put
things inside your vehicle -- like suitcases,
tools, packages, or anything else
-- they will go as fast
as the vehicle goes. If
you have to stop or turn quickly,
or
if there is a crash, they’ll keep going.
Things you put inside your vehicle can strike

By positioning four 2” x 6” wooden planks across the
width of the pickup box, you can create an upper load
platform. The planks
must be inserted in the pickup box
depressions. The length of the planks must allow for at
least a
314 inch bearing surface on each end of the plank.
When using this upper load platform, be sure the load is
securely tied down to prevent
it from shifting. The
load’s center
of gravity should be positioned in a zone
over the rear axle. The zone is located
in the area
between the front
of each fenderwell and the rear of
each fenderwell. The center of gravity height must not
extend above
the top of the pickup box flareboard.
Any load that extends beyond the vehicle’s taillamp area
must be properly marked according to local laws and
regulations.
Remember not to exceed the Gross Axle Weight Rating
(GAWR) of the rear axle. See “Loading Your Vehicle”
in the Index.
Payload
The payload capacity is shown on the Certification/Tire
label. This is the maximum load capacity that your
vehicle can carry. Be sure to include the weight of the
occupants as part of your load. If you added any
accessories or equipment after your vehicle left the
factory, remember
to subtract the weight of these things
from the payload. Your dealer can help you with this.
Add-on Equipment
When you carry removable items, you may need to put a
limit on how many people you carry inside your vehicle.
Be sure to weigh your vehicle before you buy and install
the new equipment.

If your trailer weighs more than 1,000 lbs. (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 brakes
so you’ll be able to install, adjust and
maintain them properly.
Your trailer’s brake system can tap into the vehicle’s
hydraulic brake system only if
a
a
The trailer parts can withstand 3,000 psi
(20 650 kPa) of pressure.
The trailer’s brake system will use less than
0.02 cubic inch (0.3 cc) of fluid from your vehicle’s
master cylinder. Otherwise, both braking systems
won’t work well. You could even lose your brakes.
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. Acquaint 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
as
responsive as your vehicle is by itself.
Before
you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller
by hand to be sure
the brakes are working. This lets
you check your
electrical connection at the same time.
During your trip, check occasionally
to be sure that the
load is secure, and that the lamps and any trailer brakes
are still working.

Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while
you:
Start your engine;
0 Shift into a gear; and
0 Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, belt, cooling system
and brake adjustment. Each
of these is covered in this
manual, and the Index will help
you find them quickly.
If you’re trailering, it’s
a good idea to review these
sections before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Trailer Wiring Harness
The eight-wire harness is stored under your vehicle
along
the rear frame crossmember. This harness has a
30-amp feed wire with an inline fuse located in the
instrument panel fuse block and no connector. It should
be wired by a qualified electrical technician. The
technician can use
the following color code chart when
connecting the wiring harness to your trailer.
0 DARK BLUE: Use for electric trailer brakes or
0 RED: Use for battery charging; it connects to the
LIGHT GREEN: Back-up lamps.
0 BROWN: Taillamps and parking lamps.
0 YELLOW Left stoplamp and turn signal.
0 DARK GREEN: Right stoplamp and turn signal.
0 WHITE (Heavy Gage): Ground wire.
0 WHITE (Light Gage): Auxiliary stoplamp.
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 doesn’t bend or break,
but not so
loose that it drags on the ground. Store the
harness in its original place. Wrap the harness together
and tie
it neatly so it won’t be damaged.

A vehicle can fall from a car carrier if it isn’t
adequately secured, This can cause a collision,
serious personal injury and vehicle damage. The
vehicle should be tightly secured with chains or
steel cables before
it is transported.
Don’t use substitutes (ropes, leather straps,
canvas webbing, etc.) that can be cut by sharp
edges underneath the towed vehicle. Always use
T-hooks inserted in the T-hook slots, Never use
J-hooks. They will damage drivetrain and
suspension components, When your vehicle
is being towed, have the ignition key
turned
to the OFF position. The steering wheel should
be clamped in a straight-ahead position with a clamping device designed for towing service.
Do not use the
vehicle’s steering column lock for this. The transmission
should be in
NEUTRAL (N) and the transfer case, if
you have one, should be in 2HI. The parking brake
should be released.
Don’t have your vehicle towed on the drive wheels
unless you must.
If the vehicle must be towed on the
drive wheels, be sure to follow the speed and distance
restrictions later in this section or your transmission will
be damaged. If these limitations must be exceeded, then
the drive wheels have
