possibly warm up the DEF fluid and allow the

gauge to update after a period of run time. Under

very cold conditions, it is possible that the gauge

may not reflect the new fill level for several drives.



Excessive overfilling of the DEF tank can result in

a MIL lamp/fault code and inaccurate level read

ings.

Refilling With Nozzles
You can fill up at any DEF distributor.
Proceed as follows:



Insert the DEF nozzle in the filler, start refilling and

stop refilling at the first shut-off (the shut-off indi

cates that the DEF tank is full). Do not proceed

with the refilling, to prevent spillage of DEF.



Extract the nozzle.

Refilling With Containers
Proceed as follows:



Check the expiration date.



Read the advice for use on the label before

pouring the content of the bottle into the DEF tank.



If systems which cannot be screwed in (e.g. tanks)

are used for refilling, after the indication appears

on the instrument panel display

page 104 fill

the DEF tank with no more than 2 gal (8 L).



If containers which can be screwed to the filler are

used, the reservoir is full when the DEF level in the

container stops pouring out. Do not proceed

further.

3. Stop filling the DEF tank immediately when any of the

following happen: DEF stops flowing from the fill

bottle into the DEF fill inlet, DEF splashes out the fill

inlet, or a DEF pump nozzle automatically shuts off.

4. Reinstall cap onto DEF fill inlet.

VEHICLE LOADING

ERTIFICATION

ABEL

As required by National Highway Traffic Safety

Administration regulations, your vehicle has a certification

label affixed to the driver's side door or pillar.
This label contains the month and year of manufacture,

Gross Vehicle Weight Rating (GVWR), Gross Axle Weight

Rating (GAWR) front and rear, and Vehicle Identification

Number (VIN). A Month-Day-Hour (MDH) number is

included on this label and indicates the Month, Day and

Hour of manufacture. The bar code that appears on the

bottom of the label is your VIN.

Gross Vehicle Weight Rating (GVWR)

The GVWR is the total permissible weight of your vehicle

including driver, passengers, vehicle, options and cargo.

The label also specifies maximum capacities of front and

rear axle systems (GAWR). Total load must be limited so

GVWR and front and rear GAWR are not exceeded.

CAUTION!



To avoid DEF spillage, and possible damage to the

DEF tank from overfilling, do not “top off” the DEF

tank after filling.



DO NOT OVERFILL. DEF will freeze below 12ºF

(-11ºC). The DEF system is designed to work in

temperatures below the DEF freezing point, however,

if the tank is overfilled and freezes, the system could

be damaged.



When DEF is spilled, clean the area immediately with

water and use an absorbent material to soak up the

spills on the ground.



Do not attempt to start your engine if DEF is acciden

tally added to the diesel fuel tank as it can result in

severe damage to your engine, including but not

limited to failure of the fuel pump and injectors.



Never add anything other than DEF to the tank –

especially any form of hydrocarbon such as diesel

fuel, fuel system additives, gasoline, or any other

petroleum-based product. Even a very small amount

of these, less than 100 parts per million or less than

1 oz. per 78 gal (295 L) will contaminate the entire

DEF system and will require replacement. If owners

use a container, funnel or nozzle when refilling the

tank, it should either be new or one that has only

been used for adding DEF. Mopar® provides an

attachable nozzle with its DEF for this purpose.

170

STARTING AND OPERATING

Payload

The payload of a vehicle is defined as the allowable load

weight a truck can carry, including the weight of the driver,

all passengers, options and cargo.

Gross Axle Weight Rating (GAWR)

The GAWR is the maximum permissible load on the front

and rear axles. The load must be distributed in the cargo

area so that the GAWR of each axle is not exceeded.
Each axle GAWR is determined by the components in the

system with the lowest load carrying capacity (axle,

springs, tires or wheels). Heavier axles or suspension

components sometimes specified by purchasers for

increased durability do not necessarily increase the

vehicle's GVWR.

Tire Size

The tire size on the Vehicle Certification Label represents

the actual tire size on your vehicle. Replacement tires

must be equal to the load capacity of this tire size.

Rim Size

This is the rim size that is appropriate for the tire size

listed.

Inflation Pressure

This is the cold tire inflation pressure for your vehicle for

all loading conditions up to full GAWR.

Curb Weight

The curb weight of a vehicle is defined as the total weight

of the vehicle with all fluids, including vehicle fuel, at full

capacity conditions, and with no occupants or cargo

loaded into the vehicle. The front and rear curb weight

values are determined by weighing your vehicle on a

commercial scale before any occupants or cargo are

added.

The actual total weight and the weight of the front and rear

of your vehicle at the ground can best be determined by

weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commercial

scale to ensure that the GVWR has not been exceeded.

The weight on the front and rear of the vehicle should then

be determined separately to be sure that the load is

properly distributed over the front and rear axle. Weighing

the vehicle may show that the GAWR of either the front or

rear axles has been exceeded but the total load is within

the specified GVWR. If so, weight must be shifted from

front to rear or rear to front as appropriate until the

specified weight limitations are met. Store the heavier

items down low and be sure that the weight is distributed

equally. Stow all loose items securely before driving.
Improper weight distributions can have an adverse effect

on the way your vehicle steers and handles and the way

the brakes operate.

TRAILER TOWING

In this section you will find safety tips and information on

limits to the type of towing you can reasonably do with your

vehicle. Before towing a trailer, carefully review this

information to tow your load as efficiently and safely as

possible.
To maintain the New Vehicle Limited Warranty coverage,

follow the requirements and recommendations in this

manual concerning vehicles used for trailer towing.

OMMON

OWING

EFINITIONS

The following trailer towing related definitions will assist

you in understanding the following information:

Gross Vehicle Weight Rating (GVWR)

The GVWR is the total allowable weight of your vehicle.

This includes driver, passengers, cargo and tongue

weight. The total load must be limited so that you do not

exceed the GVWR

page 169.

Gross Trailer Weight (GTW)

The GTW is the weight of the trailer plus the weight of all

cargo, consumables and equipment (permanent or

temporary) loaded in or on the trailer in its "loaded and

ready for operation" condition.
The recommended way to measure GTW is to put your fully

loaded trailer on a vehicle scale. The entire weight of the

trailer must be supported by the scale.

WARNING!

Do not load your vehicle any heavier than the GVWR or

the maximum front and rear GAWR. If you do, parts on

your vehicle can break, or it can change the way your

vehicle handles. This could cause you to lose control.

Overloading can shorten the life of your vehicle.

STARTING AND OPERATING

171

Gross Combination Weight Rating (GCWR)

The GCWR is the total permissible weight of your vehicle

and trailer when weighed in combination.

Gross Axle Weight Rating (GAWR)

The GAWR is the maximum capacity of the front and rear

axles. Distribute the load over the front and rear axles

evenly. Make sure that you do not exceed either front or

rear GAWR

page 169.

Tongue Weight (TW)

The TW is the downward force exerted on the hitch ball by

the trailer. You must consider this as part of the load on

your vehicle.

Frontal Area

The frontal area is the maximum height multiplied by the

maximum width of the front of a trailer.

Trailer Sway Control (TSC) – If Equipped

The TSC is a telescoping link that can be installed between

the hitch receiver and the trailer tongue. It typically

provides adjustable friction associated with the

telescoping motion to dampen any unwanted trailer

swaying motions while traveling.

Weight-Carrying Hitch

A weight-carrying hitch supports the trailer tongue weight,

just as if it were luggage located at a hitch ball or some

other connecting point of the vehicle. These kinds of

hitches are commonly used to tow small and medium

sized trailers.

Weight-Distributing Hitch

A Weight-Distributing Hitch works by applying leverage

through spring (load) bars. They are typically used for

heavier loads to distribute trailer tongue weight to the tow

vehicle's front axle and the trailer axle(s). When used in

accordance with the manufacturer's directions, it provides

for a more level ride, offering more consistent steering and

brake control thereby enhancing towing safety. The

addition of a friction/hydraulic sway control also dampens

sway caused by traffic and crosswinds and contributes

positively to tow vehicle and trailer stability. Trailer sway

control and a Weight-Distributing (load equalizing) Hitch

are recommended for heavier Tongue Weights (TW) and

may be required depending on vehicle and trailer

configuration/loading to comply with Gross Axle Weight

Rating (GAWR) requirements.

WARNING!

It is important that you do not exceed the maximum

front or rear GAWR. A dangerous driving condition can

result if either rating is exceeded.

WARNING!



An improperly adjusted Weight Distributing Hitch

system may reduce handling, stability, braking

performance, and could result in a collision.



Weight-Distributing Hitch Systems may not be

compatible with surge brake couplers. Consult with

your hitch and trailer manufacturer or a reputable

Recreational Vehicle dealer for additional informa

tion.

Never exceed the maximum tongue weight stamped on

your bumper or trailer hitch.

Weight Distribution

Consider the following items when computing the weight

on the rear axle of the vehicle:



The tongue weight of the trailer.



The weight of any other type of cargo or equipment put

in or on your vehicle.



The weight of the driver and all passengers.

NOTE:

Remember that everything put into or on the trailer adds

to the load on your vehicle. Also, additional

factory-installed options or dealer-installed options must

be considered as part of the total load on your vehicle.

Refer to the Tire And Loading Information Placard for the

maximum combined weight of occupants and cargo for

your vehicle.

OWING

EQUIREMENTS

To promote proper break-in of your new vehicle drivetrain

components, the following guidelines are recommended:

WARNING!

Improper towing can lead to a collision. Follow these

guidelines to make your trailer towing as safe as

possible:



Make certain that the load is secured in the trailer

and that it will not shift during travel. When trailering

cargo that is not fully secured, dynamic load shifts

can occur that may be difficult for the driver to

control. You could lose control of your vehicle and

have a collision.



When hauling cargo, or towing a trailer, do not over

load your vehicle or trailer. Overloading can cause a

loss of control, poor performance, or damage to

brakes, axle, engine, transmission, steering, suspen

sion, chassis structure, or tires.



Safety chains must always be used between your

vehicle and trailer. Always connect the chains to the

frame or hook retainers of the vehicle hitch. Cross

the chains under the trailer tongue and allow enough

slack for turning corners.



Vehicles with trailers should not be parked on a

grade. When parking, apply the parking brake on the

tow vehicle. Put the tow vehicle transmission in

PARK. Always block or "chock" the trailer wheels.



GCWR must not be exceeded.



Total weight must be distributed between the tow

vehicle and the trailer such that the following four

ratings are not exceeded:



GVWR



GTW



GAWR



Tongue weight rating for the trailer hitch utilized

CAUTION!



Do not tow a trailer at all during the first 500 miles

(805 km) the new vehicle is driven. The engine, axle

or other parts could be damaged.



Then, during the first 500 miles (805 km) that a

trailer is towed, do not drive over 50 mph (80 km/h)

and do not make starts at full throttle. This helps the

engine and other parts of the vehicle wear in at the

heavier loads.

WARNING!

STARTING AND OPERATING

(Continued)

Towing Requirements — Tires



Proper tire inflation pressures are essential to the safe

and satisfactory operation of your vehicle.



Check the trailer tires for proper tire inflation pressures

before trailer usage.



Check for signs of tire wear or visible tire damage

before towing a trailer.



Replacing tires with a higher load carrying capacity will

not increase the vehicle's GVWR and GAWR limits.



For further information

page 345.

Towing Requirements — Trailer Brakes



Do not interconnect the hydraulic brake system or

vacuum system of your vehicle with that of the trailer.

This could cause inadequate braking and possible

personal injury.



An electronically actuated trailer brake controller is

required when towing a trailer with electronically actu

ated brakes. When towing a trailer equipped with a

hydraulic surge actuated brake system, an electronic

brake controller is not required.



Trailer brakes are recommended for trailers over 1,000

lb (453 kg) and required for trailers in excess of 2,000

lb (907 kg).

Towing Requirements — Trailer Lights And

Wiring

Whenever you pull a trailer, regardless of the trailer size,

stop lights and turn signals on the trailer are required for

motoring safety.
The Trailer Tow Package may include a four- and seven-pin

wiring harness. Use a factory approved trailer harness and

connector.

NOTE:

Do not cut or splice wiring into the vehicle’s wiring

harness.

The electrical connections are all complete to the vehicle

but you must mate the harness to a trailer connector.

Refer to the following illustrations.

NOTE:



Disconnect the trailer wiring connector from the vehicle

(or any other device plugged into the vehicle's electrical

connectors) before launching a boat into water.



Be sure to reconnect once clear from water area.

Four-Pin Connector

WARNING!



Do not connect trailer brakes to your vehicle's

hydraulic brake lines. It can overload your brake

system and cause it to fail. You might not have

brakes when you need them and could have an acci

dent.



Towing any trailer will increase your stopping

distance. When towing, you should allow for addi

tional space between your vehicle and the vehicle in

front of you. Failure to do so could result in an acci

dent.

CAUTION!

If the trailer weighs more than 1,000 lb (453 kg)

loaded, it should have its own brakes and they should

be of adequate capacity. Failure to do this could lead to

accelerated brake lining wear, higher brake pedal

effort, and longer stopping distances.

OWING

IPS

Before setting out on a trip, practice turning, stopping and

backing the trailer in an area away from heavy traffic.
If using a manual transmission vehicle for trailer towing,

all starts must be in FIRST gear to avoid excessive clutch

slippage.

Automatic Transmission — If Equipped

Select the DRIVE range when towing. The transmission

controls include a drive strategy to avoid frequent shifting

when towing. However, if frequent shifting does occur

while in DRIVE, you can use the AutoStick shift control to

manually select a lower gear.

NOTE:

Using a lower gear while operating the vehicle under heavy

loading conditions, will improve performance and extend

transmission life by reducing excessive shifting and heat

buildup. This action will also provide better engine

braking.

AutoStick — If Equipped



When using the AutoStick shift control, select the

highest gear that allows for adequate performance and

avoids frequent downshifts. For example, choose “5” if

the desired speed can be maintained. Choose “4” or

“3” if needed to maintain the desired speed.



To prevent excess heat generation, avoid continuous

driving at high RPM. Return to a higher gear or vehicle

speed when grade and road conditions allow.

Cruise Control — If Equipped



Do not use in hilly terrain or with heavy loads.



When using the Cruise Control, if you experience speed

drops greater than 10 mph (16 km/h), disengage until

you can get back to cruising speed.



Use Cruise Control in flat terrain and with light loads to

maximize fuel efficiency.

bar on your vehicle. The bumper face bar will be

damaged.

WARNING!

You or others could be injured or killed if you leave the

vehicle unattended with the transfer case in the (N)

Neutral position without first fully engaging the parking

brake. The transfer case (N) Neutral position

disengages both the front and rear driveshafts from the

powertrain, and will allow the vehicle to roll, even if the

automatic transmission is in PARK (or manual

transmission is in gear). The parking brake should

always be applied when the driver is not in the vehicle.

CAUTION!

It is necessary to follow these steps to be certain that

the transfer case is fully in (N) Neutral before

recreational towing to prevent damage to internal parts.

CAUTION!

Damage to the transmission may occur if the

transmission is shifted into PARK with the transfer case

in (N) Neutral and the engine running. With the transfer

case in (N) Neutral ensure that the engine is OFF before

shifting the transmission into PARK.

Utility vehicles have higher ground clearance and a

narrower track to make them capable of performing in a

wide variety of off-road applications. Specific design

characteristics give them a higher center of gravity than

conventional passenger cars.
An advantage of the higher ground clearance is a better

view of the road, allowing you to anticipate problems. They

are not designed for cornering at the same speeds as

conventional passenger cars any more than low-slung

sports cars are designed to perform satisfactorily in

off-road conditions. Avoid sharp turns or abrupt

The Basics Of Off-Road Driving

You will encounter many types of terrain driving off-road.

You should be familiar with the terrain and area before

proceeding. There are many types of surface conditions:

hard-packed dirt, gravel, rocks, grass, sand, mud, snow

and ice. Every surface has a different effect on your

vehicle's steering, handling and traction. Controlling your

vehicle is one of the keys to successful off-road driving, so

always keep a firm grip on the steering wheel and

maintain a good driving posture. Avoid sudden

accelerations, turns or braking. In most cases, there are

no road signs, posted speed limits or signal lights.

Therefore, you will need to use your own good judgment on

what is safe and what is not. When on a trail, you should

always be looking ahead for surface obstacles and

changes in terrain. The key is to plan your future driving

route while remembering what you are currently driving

over.

NOTE:

It is recommended that the Stop/Start system and the

Forward Collision Warning (FCW) system (if equipped) be

disabled during off-road use.

When To Use 4L Range

When off-road driving, shift into 4L for additional traction

and control on slippery or difficult terrain, ascending or

descending steep hills, and to increase low speed pulling

power. This range should be limited to extreme situations

such as deep snow, mud, steep inclines, or sand where

additional low speed pulling power is needed. Vehicle

speeds in excess of 25 mph (40 km/h) should be avoided

when in 4L.

Simultaneous Brake And Throttle

Operation

Many off-road driving conditions require the simultaneous

use of the brake and throttle (two-footed driving). When

climbing rocks, logs, or other stepped objects, using light

brake pressure with light throttle will keep the vehicle from

jerking or lurching. This technique is also used when you

need to stop and restart a vehicle on a steep incline.

Driving In Snow, Mud And Sand

SNOW

In heavy snow or for additional control and traction at

slower speeds, shift the transmission into a low gear and

the transfer case into 4L if necessary. Do not shift to a

lower gear than necessary to maintain headway.

Over-revving the engine can spin the wheels and traction

will be lost. If you start to slow to a stop, try turning your

steering wheel no more than a 1/4 turn quickly back and

forth, while still applying throttle. This will allow the tires to

get fresh traction and help maintain your momentum.

MUD

Deep mud creates a great deal of suction around the tires

and is very difficult to get through. You should use DRIVE,

with the transfer case in the 4L position to maintain your

momentum. If you start to slow to a stop, try turning your

steering wheel no more than a 1/4 turn quickly back and

forth for additional traction. Mud holes pose an increased

threat of vehicle damage and getting stuck. They are

normally full of debris from previous vehicles getting

stuck. As a good practice before entering any mud hole,

get out and determine how deep it is, if there are any

hidden obstacles and if the vehicle can be safely

recovered if stuck.

WARNING!



Always wear your seat belt and firmly tie down cargo.

Unsecured cargo can become projectiles in an

off-road situation.



A malfunctioning catalytic converter can reach higher

temperatures than in normal operating conditions.

This can cause a fire if you drive slowly or park over

flammable substances such as dry plants, wood,

cardboard, etc. This could result in death or serious

injury to the driver, occupants or others.

CAUTION!

Do not use 4L when operating the vehicle on dry

pavement. Driveline hardware damage can result.

WARNING!

CAUTION!

On icy or slippery roads, do not downshift at high engine

RPM or vehicle speeds, because engine braking may

cause skidding and loss of control.

180

STARTING AND OPERATING

SAND

Soft sand is very difficult to travel through with full tire

pressure. When crossing soft, sandy spots in a trail,

maintain your vehicle's momentum and do not stop. The

key to driving in soft sand is using the appropriate tire

pressure, accelerating slowly, avoiding abrupt maneuvers

and maintaining the vehicle's momentum. If you are going

to be driving on large soft sandy areas or dunes, reduce

your tire pressure to a minimum of 15 psi (103 kPa) to

allow for a greater tire surface area. Reduced tire pressure

will drastically improve your traction and handling while

driving on the soft sand, but you must return the tires to

normal air pressure before driving on pavement or other

hard surfaces. Be sure you have a way to reinflate the tires

prior to reducing the pressure.

Crossing Obstacles (Rocks And Other

High Points)

While driving off-road, you will encounter many types of

terrain. These varying types of terrain bring different types

of obstacles. Before proceeding, review the path ahead to

determine the correct approach and your ability to safely

recover the vehicle if something goes wrong. Keeping a

firm grip on the steering wheel, bring the vehicle to a

complete stop and then inch the vehicle forward until it

makes contact with the object. Apply the throttle lightly

while holding a light brake pressure and ease the vehicle

up and over the object.

USING A SPOTTER

There are many times where it is hard to see the obstacle

or determine the correct path. Determining the correct

path can be extremely difficult when you are confronting

many obstacles. In these cases have someone guide you

over, through, or around the obstacle. Have the person

stand a safe distance in front of you where they can see

the obstacle, watch your tires and undercarriage, and

guide you through.

CROSSING LARGE ROCKS

When approaching large rocks, choose a path which

ensures you drive over the largest of them with your tires.

This will lift your undercarriage over the obstacle. The

tread of the tire is tougher and thicker than the side wall

and is designed to take the abuse. Always look ahead and

make every effort to cross the large rocks with your tires.

CROSSING A RAVINE, GULLY, DITCH,

WASHOUT OR RUT

When crossing a ravine, gully, ditch, washout or a large rut,

the angled approach is the key to maintaining your

vehicle's mobility. Approach these obstacles at a

45-degree angle and let each tire go through the obstacle

independently. You need to use caution when crossing

large obstacles with steep sides. Do not attempt to cross

any large obstacle with steep sides at an angle great

enough to put the vehicle at risk of a rollover. If you get

caught in a rut, dig a small trench to the right or left at a

45-degree angle ahead of the front tires. Use the removed

dirt to fill the rut ahead of the turnout you just created. You

should now be able to drive out following the trench you

just created at a 45-degree angle.

CROSSING LOGS

To cross a log, approach it at a slight angle (approximately

10 to 15 degrees). This allows one front tire to be on top

of the log while the other just starts to climb the log. While

climbing the log, modulate your brake and accelerator to

avoid spinning the log out from under your tires. Then ease

the vehicle off the log using your brakes.

CAUTION!

Reduced tire pressures may cause tire unseating and

total loss of air pressure. To reduce the risk of tire

unseating, while at a reduced tire pressure, reduce your

speed and avoid sharp turns or abrupt maneuvers.

WARNING!

Crossing obstacles can cause abrupt steering system

loading which could cause you to lose control of your

vehicle.

CAUTION!



Never attempt to straddle a rock that is large enough

to strike your axles or undercarriage.



Never attempt to drive over a rock which is large

enough to contact the door sills.

WARNING!

There is an increased risk of rollover when crossing an

obstacle, at any angle, with steep sides.

STARTING AND OPERATING

GETTING HIGH-CENTERED

If you get hung up or high-centered on an object, get out of

the vehicle and try to determine what the vehicle is hung

up on, where it is contacting the underbody and what is

the best direction to recover the vehicle. Depending on

what you are in contact with, jack the vehicle up and place

a few rocks under the tires so the weight is off of the high

point when you let the vehicle down. You can also try

rocking the vehicle or winching the vehicle off the object.

Hill Climbing

Hill climbing requires good judgment and a good

understanding of your abilities and your vehicle's

limitations. Hills can cause serious problems. Some are

just too steep to climb and should not be attempted. You

should always feel confident with the vehicle and your

abilities. You should always climb hills straight up and

down. Never attempt to climb a hill on an angle.

BEFORE CLIMBING A STEEP HILL

As you approach a hill, consider its grade or steepness.

Determine if it is too steep. Look to see what the traction

is on the hill side trail. Is the trail straight up and down?

What is on top and the other side? Are there ruts, rocks,

branches or other obstacles on the path? Can you safely

recover the vehicle if something goes wrong? If everything

looks good and you feel confident, shift the transmission

into a lower gear with 4L engaged, and proceed with

caution, maintaining your momentum as you climb the hill.

DRIVING UP HILL

Once you have determined your ability to proceed and

have shifted into the appropriate gear, line your vehicle up

for the straightest possible run. Accelerate with an easy

constant throttle and apply more power as you start up the

hill. Do not race forward into a steep grade; the abrupt

change of grade could cause you to lose control. If the

front end begins to bounce, ease off the throttle slightly to

bring all four tires back on the ground. As you approach

the crest of the hill, ease off the throttle and slowly

proceed over the top. If the wheels start to slip as you

approach the crest of a hill, ease off the accelerator and

maintain headway by turning the steering wheel no more

than a 1/4 turn quickly back and forth. This will provide a

fresh "bite" into the surface and will usually provide

enough traction to complete the climb. If you do not make

it to the top, place the vehicle in REVERSE and back

straight down the grade using engine resistance along

with the vehicle brakes.

DRIVING DOWNHILL

Before driving down a steep hill, you need to determine if

it is too steep for a safe descent. What is the surface

traction? Is the grade too steep to maintain a slow,

controlled descent? Are there obstacles? Is it a straight

descent? Is there plenty of distance at the base of the hill

to regain control if the vehicle descends to fast? If you feel

confident in your ability to proceed, then make sure you

are in 4L and proceed with caution. Allow engine braking

to control the descent and apply your brakes, if necessary,

but do not allow the tires to lock.

CAUTION!

Do not attempt to cross a log with a greater diameter

than the running ground clearance or the vehicle will

become high-centered.

CAUTION!

Winching or rocking the vehicle off hard objects

increases the risk of underbody damage.

WARNING!

Never attempt to climb a hill at an angle or turn around

on a steep grade. Driving across an incline increases

the risk of a rollover, which may result in severe injury.

WARNING!

Do not descend a steep grade in NEUTRAL. Use vehicle

brakes in conjunction with engine braking. Descending

a grade too fast could cause you to lose control and be

seriously injured or killed.

182

STARTING AND OPERATING

DRIVING ACROSS AN INCLINE

If at all possible, avoid driving across an incline. If it is

necessary, know your vehicle's abilities. Driving across an

incline places more weight on the downhill wheels, which

increases the possibilities of a downhill slide or rollover.

Make sure the surface has good traction with firm and

stable soils. If possible, transverse the incline at an angle

heading slightly up or down.

IF YOU STALL OR BEGIN TO LOSE HEADWAY

If you stall or begin to lose headway while climbing a steep

hill, allow your vehicle to come to a stop and immediately

apply the brake. Restart the engine and shift into

REVERSE. Back slowly down the hill allowing engine

braking to control the descent and apply your brakes, if

necessary, but do not allow the tires to lock.

Driving Through Water

Extreme care should be taken crossing any type of water.

Water crossings should be avoided, if possible, and only

be attempted when necessary in a safe, responsible

manner. Only drive through areas which are designated

and approved. Tread lightly and avoid damage to the

environment. Know your vehicle's abilities and be able to

recover it if something goes wrong. Never stop or shut a

vehicle off when crossing deep water unless you ingested

water into the engine air intake. If the engine stalls, do not

attempt to restart it. Determine if it has ingested water

first. The key to any crossing is low and slow. Shift into

FIRST gear (manual transmission), or DRIVE (automatic

transmission), with the transfer case in the 4L position

and proceed very slowly with a constant slow speed of {3

to 5 mph (5 to 8 km/h) maximum} and light throttle. Keep

the vehicle moving; do not try to accelerate through the

crossing. After crossing any water higher than the bottom

of the axle differentials, inspect all of the vehicle fluids for

signs of water ingestion.

BEFORE YOU CROSS ANY TYPE OF WATER

As you approach any type of water, you need to determine

if you can cross it safely and responsibly. If necessary, get

out and walk through the water or probe it with a stick. You

need to be sure of its depth, approach angle, current and

bottom condition. Be careful of murky or muddy waters;

check for hidden obstacles. Make sure you will not be

intruding on any wildlife, and you can recover the vehicle

if necessary. The key to a safe crossing is the water depth,

current and bottom conditions. On soft bottoms, the

vehicle will sink in, effectively increasing the water level on

the vehicle. Be sure to consider this when determining the

depth and the ability to safely cross.

CROSSING PUDDLES, POOLS, FLOODED

AREAS OR OTHER STANDING WATER

Puddles, pools, flooded or other standing water areas

normally contain murky or muddy waters. These water

types normally contain hidden obstacles and make it

difficult to determine an accurate water depth, approach

angle, and bottom condition. Murky or muddy water holes

are where you want to hook up tow straps prior to entering.

This makes for a faster, cleaner and easier vehicle

recovery. If you are able to determine you can safely cross,

than proceed using the low and slow method.

WARNING!

Driving across an incline increases the risk of a rollover,

which may result in severe injury.

WARNING!

If the engine stalls or you lose headway or cannot make

it to the top of a steep hill or grade, never attempt to

turn around. To do so may result in tipping and rolling

the vehicle, which may result in severe injury. Always

back carefully straight down a hill in REVERSE. Never

back down a hill in NEUTRAL using only the vehicle

brakes. Never drive diagonally across a hill, always drive

straight up or down.

CAUTION!



Water ingestion into the axles, transmission, transfer

case, engine or vehicle interior can occur if you drive

too fast or through too deep of water. Water can

cause permanent damage to engine, driveline or

other vehicle components, and your brakes will be

less effective once wet and/or muddy.



When driving through water, do not exceed 5 mph

(8 km/h). Always check water depth before entering

as a precaution, and check all fluids afterward.

Driving through water may cause damage that may

not be covered by the New Vehicle Limited Warranty.

CAUTION!

Muddy waters can reduce the cooling system

effectiveness by depositing debris onto the radiator.

STARTING AND OPERATING

183

CROSSING DITCHES, STREAMS, SHALLOW

RIVERS OR OTHER FLOWING WATER

Flowing water can be extremely dangerous. Never attempt

to cross a fast running stream or river even in shallow

water. Fast moving water can easily push your vehicle

downstream, sweeping it out of control. Even in very

shallow water, a high current can still wash the dirt out

from around your tires putting you and your vehicle in

jeopardy. There is still a high risk of personal injury and

vehicle damage with slower water currents in depths

greater than the vehicle's running ground clearance. You

should never attempt to cross flowing water which is

deeper than the vehicle's running ground clearance. Even

the slowest current can push the heaviest vehicle

downstream and out of control if the water is deep enough

to push on the large surface area of the vehicle's body.

Before you proceed, determine the speed of the current,

the water's depth, approach angle, bottom condition and

if there are any obstacles. Then cross at an angle heading

slightly upstream using the low and slow technique.

After Driving Off-Road

Off-road operation puts more stress on your vehicle than

does most on-road driving. After going off-road, it is always

a good idea to check for damage. That way you can get any

problems taken care of right away and have your vehicle

ready when you need it.



Completely inspect the underbody of your vehicle.

Check tires, body structure, steering, suspension, and

exhaust system for damage.



Inspect the radiator for mud and debris and clean as

required.



Check threaded fasteners for looseness, particularly

on the chassis, drivetrain components, steering, and

suspension. Retighten them, if required, and torque to

the values specified in the Service Manual.



Check for accumulations of plants or brush. These

things could be a fire hazard. They might hide damage

to fuel lines, brake hoses, axle pinion seals, and

propeller shafts.



After extended operation in mud, sand, water, or

similar dirty conditions, have the radiator, fan, brake

rotors, wheels, brake linings, and axle yokes inspected

and cleaned as soon as possible.

NOTE:

Inspect the clutch vent holes in the manual transmission

bell housing for mud and debris and clean as required.



If you experience unusual vibration after driving in

mud, slush or similar conditions, check the wheels for

impacted material. Impacted material can cause a

wheel imbalance and freeing the wheels of it will

correct the situation.

WARNING!

Never drive through fast moving deep water. It can push

your vehicle downstream, sweeping it out of control.

This could put you and your passengers at risk of injury

or drowning.

WARNING!

Abrasive material in any part of the brakes may cause

excessive wear or unpredictable braking. You might not

have full braking power when you need it to prevent a

collision. If you have been operating your vehicle in dirty

conditions, get your brakes checked and cleaned as

necessary.
