kmrting Your Engine
Engines start differently. The 8th digit of your Vehicle Identification Number
(VIN) shows the code letter or number for your engine. You
will find the VIN
at the top left of your instrument panel. (See “Vehicle Identification Number\
”
in the Index.) Follow the proper steps to start the engine.
To Start Your 5.7 Liter (Code K) engine
or
7.4 Liter (Code N) engine:
1. Automatic Transmission
Move your shift lever to P (Park) or N (Neutral). Your engine won’t start
in any other position-that’s a safety feature. To restart when you’re
already moving, use
N (Neutral) only.

I NOTICE
Cruise Control (Option)
K2247
With Cruise Control, you can maintain a speed of about 25 mph (40 km/h)
or more without keeping your foot on the accelerator. This can\
really help
on long trips. Cruise Control does not work at speeds below a\
bout
25 mph
(40 krn/h).
When you apply your brakes, or the clutch pedal,
if you have a manual
transmission, the Cruise Control shuts
off.

2. To slow down in very small amounts, push the button for less than half
a second. Each time you do this, you'll
go about 1 mph (1.6 kmlh)
slower.
Passing Another Vehicle While Using Cruise Control
Use the accelerator pedal to increase your speed. When you take your foot
off the pedal, your vehicle will slow down to the Cruise Control \
speed you set
earlier.
Using Cruise Control on Hills
How well your Cruise Control will work on hills depends upon your speed,
load, and the steepness of the hills. When going up steep hil\
ls, you may
have to step on the accelerator pedal to maintain your speed. When going
downhill, you may have to brake or shift to
a lower gear to keep your speed
down. Of course, applying the brake takes you out of Cruise Control. Many
drivers find this to be
too much trouble and don't use Cruise Control on
steep hills.
To Get Out of Cruise Control
There are several ways to turn off the Cruise Control:
.Y ..
1. Step lightly on the brake pedal or push the clutch pedal, if you have a
manual transmission; OR
2. Move the Cruise switch to OFF.
When you turn off the Cruise Control or the ignition, your Cruise Control set

Here are some things you must not do if you stall, or are about to stall,
when going up a hill.
Never attempt to prevent a stall by shifting into N (Neutral) (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 into reverse, release the parking brake, and slowl\
y back down.
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 down the hill.
Q: Suppose, after stalling, I try to back down the hill and decide I just
can’t
do it. What should I do?
A: Set the parking brake, put your transmission in P (Park) (or the manual
transmission in first gear), and turn
off the engine. Leave the vehicle and go
get some help. Exit
on the uphill side and stay clear of the path the vehicle
would take
if it rolled downhill. Do not shift the transfer case to N (Neutral)
when you leave the vehicle. Leave
it in some gear.
Shifting the transfer case to N (Neutral) can cause your vehicle to

(Neutral) position on the transfer case overrides the transmission. If
you are going to leave your vehicle, set the parking brake and shift
the transmission to P (Park) (or, put your manual transmission in first
gear). But do not shift the transfer case to the N (Neutral) position.

Driving Downhill
When off-roading takes you downhill, you’ll want to consider a number of
things:
How steep is the downhill? Will I be able to maintain vehicle control?
What’s the surface like? Smooth? Rough? Slippery? Hard-packed \
dirt?
Are there hidden surface obstacles? Ruts? Logs? Boulders?
Gravel?

What’s at the bottom of the hill? Is there a hidden creek bank or even a
river bottom with large rocks?
If you decide you can go down a hill safely, then try to keep your vehicle
headed straight down, and use a low gear. This way, engine drag can help
your brakes and they won’t have to do all the work. Descend slowly, keeping
your vehicle under control at all times.
’ [ Heavy braking when going down a hill can cause your brakes to
overheat and fade. This could cause
loss of control and a serious
accident. Apply the brakes lightly when descending a hill and use a
I low gear to keep vehicle speed under control. 1
Q: Are there some things I should not do when driving down a hill?
A: Yes! These are important because if you ignore them you could lose
control and have
a serious accident.
When driving downhill, avoid turns that take you &%C>Ss the incline of the
hill.
A hill that’s not too steep to drive down may be too steep to drive
across. You could roll over
if you don’t drive straight down.
Never go downhill with the transmission in N (Neutral), or with the clutch
pedal depressed in a manual shift. This is called “free-wheeling.” Your
brakes will have to do all the work and could overheat and fade.
Q: Am I likely to stall when going downhill?
A: It’s much more likely to happen going uphill, But if it happens going
downhill, here’s what to do.
Stop your vehicle by applying the regular brakes. Apply the parking

down.
If the engine won’t start, get out and get help.
Driving Across an Incline
Sooner or later, an off-road trail will probably go across the incline of a hill. If
this happens, you have to decide whether to try
to drive across the incline.
Here are
some things to consider:

Engine Fan Noise
This vehicle has a clutched engine cooling fan. When the clutc\
h is engaged,
the fan spins faster
to provide more air to cool the engine. In most every day
driving conditions the clutch is not engaged. This improves fuel economy and
reduces fan noise. Under heavy vehicle loading, trailer towing \
and/or high
outside temperatures, the fan speed increases when the clutch e\
ngages.
So
you may hear an increase in fan noise. This is normal and sh\
ould not be
mistaken
as the transmission slipping or making extra shifts. It is merely the
cooling system functioning properly. The fan
will slow down when additional
cooling is not required and the clutch disengages.
You may also hear this fan noise when you start the engine. \
It will go away
as the fan clutch disengages.
If a Tire Goes Fiat
It’s unusual for a tire to “blow out” while you’re driving,\
especially if you
maintain your tires properly.
If air goes out of a tire, it’s much more likely to
leak out slowly. But if you should ever have a “blowout,” here are a few tips
about what
to expect and what to do:
If a front tire fails, the flat tire will create a drag that pulls the vehicle toward
that side. Take your foot
off the accelerator pedal and grip the steering wheel
firmly. Steer to maintain lane position, then gently brake
to a stop well out of
the traffic lane.
A rear blowout, particularly on a curve, acts much like a skid and may
require the same correction you’d use in a skid. In any rear blowout, remove
your foot from the accelerator pedal. Get the vehicle under co\
ntrol by steering
the way you want the vehicle
to go. It may be very bumpy and noisy, but
you can still steer. Gently brake to a stop, well off the road if possible.
If your tire goes flat, the next part shows how to use your jacking equipment
to change a flat tire safely.
Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage by driving slowly to a
level place. Turn
on your hazard warning flashers.
