It makes sense to plan your trip, especially when going
to a remote 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
vehicle. 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.
Getting Familiar with Off-Road Driving
It’s a good idea to practice in an area that’s safe and
close to home before you
go into the wilderness.
Off-road
driving does require some new and different
driving
skills. Here’s what we mean.
Tune your senses to different kinds of signals. Your
eyes. for example, need to constantly sweep the terrain
for unexpected obstacles. Your ears need to listen for
unusual tire
or engine sounds. With your arms, hands,
feet and body, you’ll need to respond to vibrations and
vehicle bounce. Controlling
your vehicle is the key to successful
off-road driving. One of
the best ways to control your
vehicle is to control your speed. Here are some things to
keep
in mind. At higher speeds:

you approach things faster and you have less time to
scan the terrain for obstacles.
you have less time to react.
you have more vehicle bounce when you drive
over obstacles.
you’ll need more distance for braking, especially
since you’re on
an unpaved surface.
I A CAUTION:
When you’re driving off-road, bouncing and
quick changes in direction can easily throw you
out
of position. This could cause you to lose
control and crash. So, whether you’re driving on
or off the road, you and your passengers should
wear safety belts.

Off-road driving often takes you up, down or across a
hill. Driving safely
on hills requires good judgment and
an understanding
of what your vehicle can and can’t do.
There are some hills that simply can’t be driven,
no
matter how well built the vehicle. incline
may get steeper as
you near the top, but you may
not see this because
the crest of the hill is hidden by
bushes, grass or shrubs.
Here are some other things
to consider as you approach
a
hill.
0
I A CAUTION: 0
Many hills are simply too steep for any vehicle. If
you drive up them, you will stall. If you drive
down them, you can’t control your speed.
If you
drive across them, you will roll over.
You could be
~ seriously injured or killed. If you have any doubt
~ about the steepness, don’t drive the hill.
Approaching a Hill
When you approach a hill, you need to decide if it’s one
of those hills that’s just too steep to climb, descend or
cross. Steepness can be hard to judge. On a very small
hill, for example, there
may be a smooth. constant
incline with
only a small change in elevation where you
can easily see all the way to the top. On a large hill, the

Is there a constant incline, or does the hill get sharply
steeper in places?
Is there good traction on the hillside, or will the
surface cause tire slipping?
Is there a straight path up or down the hill so you
won’t have to make turning maneuvers?
Are there obstructions on the
hill that can block your
path (boulders. trees, logs or ruts)?
What’s beyond the hill?
Is there a cliff, an
embankment. a drop-off,
a fence? Get out and walk
the
hill if you don’t know. It’s the smart way to
find out.
Is the hill simply too rough? Steep hills often have
ruts, gullies, troughs and exposed rocks because they
are more susceptible
to the effects of erosion.

to stall, and I can’t make it up the hill?
do. and there are some things you must not do.
First, here’s what
you should do:
0 Push the brake pedal to stop the vehicle and keep it
from rolling backwards. Also, apply the parking brake.
0 If your engine is still running, shift the transmission
to REVERSE
(R), release the parking brake, and
slowly back down the hill
in REVERSE (R).
0 If your engine has stopped running, you’ll need to
restart it. With the brake pedal depressed and the
parking brake still applied, shift
the transmission to
PARK (P) (or, shift to NEUTRAL (N) if your
vehicle has a manual transmission) and restart
the
engine. Then, shift to REVERSE (R), release the
parking brake, and slowly back down the
hill as
straight as possible in REVERSE (R).
As you are backing down the hill, put your left hand
on the steering wheel at the 12 o’clock position. This
way, you’ll be able
to tell if your wheels are straight
and maneuver
as you back down. It’s best that you
back down the hill with your wheels straight rather
than
in the left or right direction. Turning the wheel
too far to the left or right will increase the possibility
of
a rollover.
Here are some things
you must not do if you stall, or are
about
to stall, when going up a hill.
0 Never attempt to prevent a stall by shifting into
NEUTRAL
(N) (or depressing the clutch, if you
have
a manual transmission) to “rev-up” the engine
and regain forward momentum. This
won’t work.
Your vehicle will roll backwards very quickly and
you could go out of control.
Instead, apply the regular brake
to stop the
vehicle. Then apply
the parking brake. Shift to
REVERSE
(R), release the parking brake, and
slowly back straight down.
0 Never attempt to turn around if you are about to stall
when going up
a hill. If the hill is steep enough to
stall your vehicle, it’s steep enough to cause you to
roll over if you turn around. If you can’t make it up
the hill, you must back straight down the hill.

What’s the worst time for this’? “Wet ice.“ Very cold
snow or ice can be slick and hard
to drive on. But wet
ice can be even more trouble because
it may offer the
least traction
of all. You can get wet ice when it’s about
freezing
(32°F; OOC) and freezing rain begins to fall.
Try to avoid driving on wet ice until salt and sand crews
can get there. Whatever
the condition
-- smooth ice, packed, blowing
or loose snow
-- drive with caution.
Accelerate gently. Try
not to break the fragile traction. If
you accelerate too fast. the drive wheels will spin and
polish the surface under the tires even more.
Your anti-lock brakes improve your vehicle’s stability
when you make a hard stop
on a slippery road. Even
though
you have an anti-lock braking system, you’ll
want
to begin stopping sooner than you would on dry
pavement. See “Anti-Lock” in
the Index.
Allow greater following distance on any
slippery road.
Watch for slippery spots. The road might be fine
until you hit a spot that’s covered with ice. On an
otherwise clear road, ice patches may appear in
shaded areas where the sun can’t reach: around
clumps
of trees, behind buildings or under bridges.
Sometimes the surface of a curve or an overpass may
remain icy
when the surrounding roads are clear. If
you see a patch of ice ahead of you, brake before you
are on it. Try not to brake while you’re actually on
the ice, and avoid sudden steering maneuvers.

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
Snow can trap exhaust gases under your vehicle.
This can cause deadly
CO (carbon monoxide) gas
to get inside.
CO could overcome you and kill
you. You can’t see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that
is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn’t collect there.
Open a window just
a little on the side of the
vehicle that’s away from the wind. This
will help
keep CO out.
Run your engine only as long as you must. This saves
fuel. When
you run the engine, make it 90 a little faster
than
just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged.
You will need a well-charged battery to
restart the vehicle. and possibly for signaling later on
with your headlamps. Let the heater
run for a while.
Then. shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when
you feel really uncomfortable
from the
cold. But do it as little as possible. Preserve the
fuel
as long as you can. To help keep warm. you can get
out of the vehicle
and do some fairly vigorous exercises
every
half hour or so until help comes.

The light duty trailer wiring is a six-wire harness
assembly. The optional heavy-duty trailer wiring is an
eight-wire harness assembly. The harnesses are stored
under the vehicle, along the passenger-side frame
crossmember on two-door vehicles or on the driver’s
side corner frame crossmember on four-door vehicles.
The heavy-duty trailer wiring has
a 30-amp feed wire
with an inline
fuse located by the junction block. See
“Fuses and Circuit Breakers”
in the Index. Both
harnesses have no connector and 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.
Dark Blue: Use for electric trailer brakes or
auxiliary wiring.
0 Red: Use for battery charging; it connects to the
starter solenoid (eight-wire harness only).
0 Light Green: Back-up lamps (eight-wire
harness only).
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.

Downloaded from www.Manualslib.com manuals search engine 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.
If your vehicie has a floor mounted shifter and no
electrical power, the electrical solenoid lock must be
overridden
to shift from PARK (P) to NEUTRAL (N).
Follow these steps:
1. Push the base of the shift lever boot forward with
your thumb.
2. Lift the boot and find the white solenoid lever.

1. You can remove the pressure cap when the cooling
system, including the pressure cap and upper radiator
hose, is no longer hot. Turn the pressure cap slowly
counterclockwise
until it first stops. (Don't press
down while turning the pressure cap.)
If you hear a hiss. wait for that to stop. A hiss means
there is still some pressure left.
2. Then keep turning the pressure cap, but now push
down as you turn it. Remove the pressure cap.
