among three driving settings:
0
0
0
2HI - This setting is for driving in most street and highway situations.
Your front axle
is not engaged in two-wheel drive.
4HI - This setting engages your front axle to help drive your vehicle.
Use 4HI when you need extra traction, such as
on snowy or icy roads,
or
in most off-road situations.
4LO - This setting also engages your front axle to give you extra
traction. You may never need
4LO. It sends the maximum power to all
four wheels. You might choose
4LO if you were driving off-road in
sand, mud, deep snow and climbing or descending steep hills.
Amber indicator lights
in the switches show you which setting you are in.
The indicator lights will come on briefly when you turn on the ignition and
one will stay
on. If the lights do not come on, you should take your vehicle
in for service. When shifting, an indicator light will flash until the shift is
completed then remain solidly lit.
To shift from 2HI to 4HI - Press and release the 4HI switch. This can be
done at any speed, and the front axle will lock automatically.
To shift from 4HI to 2HI - Press and release the 2HI switch. This can be
done at any speed, and the front axle will unlock automatically.
To shift from 2H1, or 4HI to 4LO - The vehicle must be stopped or
moving less than
3 mph (4.8 km/h) with the transmission in NEUTRAL (N)
in vehicles equipped with an automatic transmission or the clutch pedal
depressed
in vehicles equipped with a manual transmission. The preferred
method for shifting into
4LO is to have your vehicle slowly moving 1 to 2
mph (1.6 to 3.2 kdh). Press and release the 4LO switch. You must wait for
the amber
4LO indicator light to stop flashing and go solid amber before
shifting your transmission into gear or releasing
the clutch pedal.

Downloaded from www.Manualslib.com manuals search engine Normal operating range shows your engine speed during normal driving
conditions. For example, when the needle points
to 2, it means the engine is
running at
2,000 revolutions per minute (rpm). The tachometer needle will
vary all the time that the engine is running.
The red warning range tells you that your engine speed is reaching its upper
limits. Don’t drive very long with the tachometer in the red warning range.
If you have a manual transmission, shift to a higher gear as soon as possible.
If you have an automatic transmission, lift your foot off of the accelerator
pedal. If
you drive for very long with the tachometer in the red danger
range, engine damage will result.
I NOTICE:
Do not operate the engine with the tachometer in the red range,
or engine damage
will occur.
The red danger range tells you that your engine speed is at its upper limits.
You should immediately shift to a higher gear, or lift your
foot off of the
accelerator pedal. If you drive for very long with the tachometer in the red
danger range, engine damage will result.
Warning Lights and Indicators
This part describes the warning lights and gages that may be on your
vehicle.
The pictures will help you locate them.
Warning lights and gages can signal that something is wrong before it
becomes serious enough
to cause an expensive repair or replacement.
Paying attention to your warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a problem with one of your
vehicle’s functions.
As you will see in the details on the next few pages,
some warning lights come on briefly when you start the engine just to let
you know they’re working. If
you are familiar with this section, you should
not be alarmed when this happens.
Gages can indicate when there may be or is a problem with one
of your
vehicle’s functions. Often gages and warning lights work together to let you
know when there’s a problem with your vehicle.
When one
of the warning lights comes on and stays on when you are
driving, or when one
of the gages shows there may be a problem, check the
section that
tells you what to do about it. Please follow this manual’s advice.
Waiting to do repairs can be costly
- and even dangerous. So please get to
know your warning lights and gages. They’re a big help.

If you wish to use a power winch on your vehicle, only use it when your
vehicle
is stationary or anchored.
I NOTICE:
-
Operating a power winch with an automatic transmission in
PARK
(P) or a manual transmission in gear may damage the
transmission. Always put the transmission
in a Neutral position
while operating
a power winch.
Use the regular brakes, set the parking brake or block the wheels to keep
your vehicle from rolling.
If your vehicle is equipped with an airbag, see “Adding Equipment to Your
Air Bag-Equipped Vehicle” in the Index.
Recreational Vehicle Towing (Four- Wheel
Drive Only)
If your vehicle has four-wheel drive, you may tow it behind another vehicle
providing it does not have the optional electronic shift transfer case.
I NOTICE:
Recreational vehicle towing is not recommended for vehicles
with the optional electronic shift transfer case because the
electronic shift has no neutral position.
Before towing, you should:
1. Set the parking brake firmly.
2. Place the automatic transmission in PARK (P) or the manual
transmission in the lowest gear
(FIRST GEAR).

Downloaded from www.Manualslib.com manuals search engine Don’t tow a trailer at all during the first 500 miles (800 km) your new
vehicle is driven. Your engine, axle or other parts could be damaged.
Then, during the first 500 miles (800 km) that you tow a trailer, don’t
drive over
50 mph (80 km/h) and don’t make starts at full throttle. This
helps your engine and other parts of your vehicle wear in at the heavier
loads.
If you have an automatic transmission, you should use DRIVE (D) (or,
as you need to, a lower gear) when towing a trailer. Operating your
vehicle
in DRIVE (D) when towing a trailer will minimize heat
build-up and extend the life of your transmission. If you have a manual
transmission and you are towing a trailer, it’s better not to use
FIFTH
(5) gear. Just drive in FOURTH (4) gear (or, as you need to, a lower
gear)-
Three important considerations have to do with weight:
Weight of the Trailer
How heavy can a trailer safely be?
It depends on how you plan to use your rig. For example, speed, altitude,
road grades, outside temperature and how much your vehicle is used to pull
a trailer are all important. And, it can also depend on any special equipment
that you have on your vehicle.
You can ask your dealer for our trailering information
or advice, or you can
write us at the address listed in your Warranty and Owner Assistance
Information Booklet.

Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important weight to measure
because it affects the total or gross weight of your vehicle. The gross vehicle
weight (GVW) includes the curb weight of the vehicle, any cargo you may
carry in it, and the people who will be riding in the vehicle. And if you will
tow a trailer, you must add the tongue load to the GVW because your
vehicle will be carrying that weight, too. See “Loading Your Vehicle” in the
Index for more information about your vehicle’s maximum load capacity.

Downloaded from www.Manualslib.com manuals search engine Driving On Grades
Reduce speed and shift to a lower gear before you start down a long or steep
downgrade. If you don’t shift down, you might have to use your brakes
so
much that they would get hot and no longer work well.
On a long uphill grade,
shift down and reduce your speed to around 45 mph
(70 km/h) to reduce the possibility of engine and transmission overheating.
When towing at high altitude on steep uphill grades, consider the following:
Engine coolant will boil at a lower temperature than at normal altitudes. If
you
turn your engine off immediately after towing at high altitude on steep
uphill grades, your vehicle may show signs similar to engine overheating.
To avoid this, let the engine run while parked (preferably on level ground)
with the automatic transmission in PARK
(P) (or the manual transmission
out of gear and the parking brake applied) for
a few minutes before turning
the engine
off. If you do get the overheat warning, see “Engine
Overheating” in the Index.
Parking on Hi//s
You really should not park your vehicle, with a trailer attached, on a hill. If
something goes wrong, your rig could start to move. People can be injured,
and both your vehicle and the trailer can be damaged.
But if you ever have to park your rig on a hill, here’s how to do it:
1. Apply your regular brakes, but don’t shift into PARK (P) yet, or into
gear for a manual transmission. When parking uphill,
turn your wheels
away from the curb. When parking downhill,
turn your wheels into the
curb.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until the
chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking brake, and then
shift into PARK
(P), or REVERSE (R) for a manual transmission.
5. If you have a four-wheeldrive vehicle with a manual transfer case
shift lever, be sure the transfer case is
in a drive gear - not in
NEUTRAL (N).
6. Release the parking brake.

Downloaded from www.Manualslib.com manuals search engine When You Are Ready to Leave After Parking on a Hill
1. Apply your regular brakes and hold the pedal down while you:
Start your engine;
Shift into a gear; and
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.
