page 404.

Remove cap from DEF tank (located on drivers side

of the vehicle or in fuel door).

DEF Filler Cap And Fuel Fill Chassis Cab Models

NOTE:



The DEF gauge may take up to five seconds to

update after adding a gallon or more of DEF to

the DEF tank. If you have a fault related to the

DEF system, the gauge may not update to the

new level. See an authorized dealer for service.



The DEF gauge may also not immediately

update after a refill if the temperature of the

DEF fluid is below 39°F (4°C). The DEF tank

heater will 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.



At 40°F (4°C) you could see some increase in

the DEF gauge due to the tank thawing. The

gauge and level sensor are working properly and

are just updating with proper thawed DEF.



Excessive overfilling of the DEF tank can result

in a MIL lamp/fault code and inaccurate level

readings.

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



Insert the DEF nozzle in the filler tube, start

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

shut-off indicates 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.



After the indication appears on the instrument

cluster display

Ú

page 81 fill the DEF tank with

no more than 6 gallons (22 liters).

1 — Diesel Exhaust Fluid (DEF) Fill Location
2 — Diesel Fuel Fill Location

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 immedi

-

ately with water and use an absorbent mate

-

rial to soak up the spills on the ground.



Do not attempt to start your engine if DEF is

accidentally 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.

172

STARTING AND OPERATING

Stop filling the DEF tank immediately if DEF

splashes or wells back in the filler neck.
Reinstall cap onto DEF filler tube.
Filling The Def Tank In Cold Climates
Since DEF will begin to freeze at 12°F (-11°C),

your vehicle is equipped with an automatic DEF

heating system. This allows the DEF injection

system to operate properly at temperatures below

12°F (-11°C). If your vehicle is not in operation for

an extended period of time with temperatures

below 12°F (-11°C), the DEF in the tank may

freeze. If the tank is overfilled and freezes, it could

be damaged. Therefore, do not overfill the DEF

tank.

Extra care should be taken when filling with

portable containers to avoid overfilling. Note the

level of the DEF gauge in your instrument cluster.

You may safely add a maximum of 2 gallons

(7.5 liters) of DEF from portable containers when

your DEF gauge is reading ½ full.

(GVWR)

The GVWR is the total permissible weight of your

maximum capacities of front and rear axle systems

(GAWR). Total load must be limited so GVWR and

front and rear GAWR are not exceeded.

(GAWR)

The GAWR is the maximum permissible load on the

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 does not

necessarily increase the vehicle's GVWR.

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.



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 gallons

(295 liters) 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.

CAUTION!

STARTING AND OPERATING

173

L

OADING

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 axles. Weighing the vehicle may

show that the GAWR of either the front or rear axle

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.

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

Ú

page 172.

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.

CAUTION!

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.

WARNING!

If the gross trailer weight is 5,000 lb (2,267 kg)

or more, it is recommended to use a

weight-distributing hitch to ensure stable

handling of your vehicle. If you use a standard

weight-carrying hitch, you could lose control of

your vehicle and cause a collision.

4

174

STARTING AND OPERATING

Gross Combination Weight Rating (GCWR)

The GCWR is the total allowable 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

Ú

page 172.

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.

Trailer Frontal Area

The frontal area is the maximum height multiplied

by the maximum width of the front of a trailer.

Trailer Sway Control (TSC)

The TSC can be a mechanical telescoping link that

can be installed between the hitch receiver and the

trailer tongue that typically provides adjustable

friction associated with the telescoping motion to

dampen any unwanted trailer swaying motions

while traveling.
If equipped, the electronic TSC recognizes a

swaying trailer and automatically applies individual

wheel brakes and/or reduces engine power to

attempt to eliminate the trailer sway.

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 system 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

(TSC) 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 GAWR requirements.

Without Weight-Distributing Hitch (Incorrect)

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. You could lose control of the vehicle

and have a collision.

WARNING!



An improperly adjusted weight-distributing

hitch system may reduce handling, stability

and braking performance and could result in a

collision.



Weight-distributing systems may not be

compatible with surge brake couplers. Consult

with your hitch and trailer manufacturer or a

reputable Recreational Vehicle dealer for

additional information.

the front fender is approximately (H2-H1)/

2+H1 (about 1/2 the difference between

H2 and H1 above normal ride height [H1]).

6. Perform a visual inspection of the trailer and

weight-distributing hitch to confirm manufac

-

turers’ recommendations have been met.

NOTE:

For all towing conditions, we recommend towing

with TOW/HAUL mode engaged.

Fifth-Wheel Hitch

The fifth-wheel hitch is a special high platform with

a coupling that mounts over the rear axle of the tow

vehicle in the truck bed. It connects a vehicle and

fifth-wheel trailer with a coupling king pin.
Your truck may be equipped with a fifth-wheel hitch

option. Refer to the separately provided fifth-wheel

hitch safety, care, assembly, and operating



The tongue weight of the trailer.



The weight of any other type of cargo or equip

-

ment 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

EQUIREMENTS

To promote proper break-in of your new vehicle

drivetrain components, the following guidelines

are recommended.

Perform the maintenance listed in the “Scheduled

Servicing”

Ú

page 328. When towing a trailer,

never exceed the GAWR or GCWR ratings.

CAUTION!

Always load a trailer with 60% of the weight in

the front of the trailer. This places 10% of the

GTW on the tow hitch of your vehicle. Loads

balanced over the wheels or heavier in the rear

can cause the trailer to sway severely side to

side which will cause loss of control of the

vehicle and trailer. Failure to load trailers heavier

in front is the cause of many trailer collisions.

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!



Make certain that the load is secured in the

trailer and 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

overload your vehicle or trailer. Overloading

can cause a loss of control, poor performance

or damage to brakes, axle, engine, transmis

-

sion, steering, suspension, chassis structure

or tires.

CAUTION!

STARTING AND OPERATING

Towing Requirements — Tires



Do not attempt to tow a trailer while using a

compact spare tire.



Do not drive more than 50 mph (80 km/h) when

towing while using a full size spare tire.



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.



For the proper tire replacement procedures.

Replacing tires with a higher load carrying

capacity will not increase the vehicle's GVWR

and GAWR limits.



For further information

Ú

page 376.

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 actuated 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).



Safety chains must always be used between

your vehicle and trailer. Always connect the

chains to the 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. For four-wheel drive

vehicles, make sure the transfer case is not in

NEUTRAL. 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.

WARNING!

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 accident.



Towing any trailer will increase your stopping

distance. When towing, you should allow for

additional space between your vehicle and the

vehicle in front of you. Failure to do so could

result in an accident.

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.

Integrated Trailer Brake Module (ITBM) —

If Equipped

Your vehicle may have an ITBM for Electric and

Electric Over Hydraulic (EOH) trailer brakes.

NOTE:

This module has been designed and verified with

electric trailer brakes and new electric over

hydraulic systems. Some previous EOH systems

may not be compatible with ITBM.

Integrated Trailer Brake Module (ITBM)

The user interface consists of the following:
Manual Brake Control Lever
Slide the manual brake control lever to the left to

activate power to the trailer's electric brakes

independent of the tow vehicle's brakes. If the

manual brake control lever is activated while the

brake is also applied, the greater of the two inputs

determines the power sent to the trailer brakes.
The trailer and the vehicle’s stop lamps will come

on when braking normally with the vehicle brake

pedal. Only the trailer stop lamps will come on

when the manual brake control lever is applied.
Trailer Brake Status Indicator Light
This light indicates the trailer electrical connection

status.
If no electrical connection is detected after the

ignition is turned on, pushing the GAIN adjustment

button or sliding the manual brake control lever

will display the GAIN setting for 10 seconds and the

Trailer Brake Status Indicator Light will not be

displayed.
If a fault is detected in the trailer wiring or the ITBM,

the Trailer Brake Status Indicator Light will flash.
GAIN Adjustment Buttons (+/-)
Pushing these buttons will adjust the brake control

power output to the trailer brakes in

0.5 increments. The GAIN setting can be increased

to a maximum of 10 or decreased to a minimum of

0 (no trailer braking).

GAIN
The GAIN setting is used to set the trailer brake

control for the specific towing condition and should

be changed as towing conditions change. Changes

to towing conditions include trailer load, vehicle

load, road conditions and weather.
Adjusting GAIN

NOTE:

This should only be performed in a traffic-free envi

-

ronment at speeds of approximately 20–25 mph

IPS

Before setting out on a trip, practice turning,

stopping, and backing up the trailer in an area

located away from heavy traffic.

Automatic Transmission

The DRIVE range can be selected when towing. The

transmission controls include a drive strategy to

avoid frequent shifting when towing. However, if

frequent shifting does occur while in DRIVE, select

TOW/HAUL mode or select a lower gear range

(using the Electronic Range Select (ERS) shift

control).

NOTE:

Using TOW/HAUL mode or selecting a lower gear

range (using the ERS shift control) while operating

the vehicle under heavy loading conditions will

improve performance and extend transmission life

by reducing excessive shifting and heat build-up.

This action will also provide better engine braking.
6-Speed Automatic Transmission Only
When towing a loaded trailer up steep grades at

low speeds (20 mph [32 km/h] or below), holding

your vehicle in FIRST gear (using the ERS shift

control) can help to avoid transmission

overheating.

STARTING AND OPERATING

183

If you regularly tow a trailer for more than

45 minutes of continuous operation, then change

the automatic transmission fluid and filter(s) as

specified for "police, taxi, fleet, or frequent trailer

towing."

Ú

page 329.

NOTE:

Check the automatic transmission fluid level

before towing (6-speed automatic only).

Tow/Haul Mode

To reduce potential for automatic transmission

overheating, activate TOW/HAUL mode when

driving in hilly areas, or select a lower gear range

(using the Electronic Range Select (ERS) shift

control) on more severe grades.

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.

SNOWPLOW — IF EQUIPPED

Snowplow Prep Packages are available as a factory

installed option. These packages include

components necessary to equip your vehicle with a

snowplow.

NOTE:

Before installation of a snowplow it is highly recom

-

mended that the owner/installer obtain and follow

the recommendations contained within the current

Body Builder’s Guide. See an authorized dealer,

installer or snowplow manufacturer for this infor

-

mation. There are unique electrical systems that

must be connected to properly ensure operator

safety and prevent overloading vehicle systems.

STARTING AND OPERATING

The loaded vehicle weight, including the snowplow

system, all aftermarket accessories, driver,

passengers, options, and cargo, must not exceed

either the Gross Vehicle Weight Rating (GVWR) or

Gross Axle Weight Rating (GAWR). These weights

are specified on the Safety Compliance

Certification Label on the driver's side door

opening.

NOTE:

Detach the snowplow when transporting

passengers.
Vehicle front end wheel alignment was set to

specifications at the factory without consideration

for the weight of the plow. Front end toe-in should

be checked and reset if necessary at the beginning

and end of the snowplow season. This will help

prevent uneven tire wear.
The blade should be lowered whenever the vehicle

is parked.
Maintain and operate your vehicle and snowplow

equipment following the recommendations

provided by the specific snowplow manufacturer.

The blade restricts air flow to the radiator and

causes the engine to operate at higher than

normal temperatures. Therefore, when

transporting the plow, angle the blade completely

and position it as low as road or surface conditions

permit. Do not exceed 40 mph (64 km/h). The

operator should always maintain a safe stopping

distance and allow adequate passing clearance.

O

PERATING

IPS

Under ideal snow plowing conditions, 20 mph

(32 km/h) should be maximum operating speed.

The operator should be familiar with the area and

surface to be cleaned. Reduce speed and use

extreme caution when plowing unfamiliar areas or

under poor visibility.

AINTENANCE

Snowplows should be maintained in accordance

with the plow manufacturer's instructions.
Keep all snowplow electrical connections and

battery terminals clean and free of corrosion.
When plowing snow, to avoid transmission and

drivetrain damage, the following precautions

should be observed.



Operate with transfer case in 4WD LOW when

plowing small or congested areas where speeds

are not likely to exceed 15 mph (24 km/h). At

higher speeds operate in 4WD HIGH.



Vehicles with automatic transmissions should

use 4WD LOW when plowing deep or heavy

snow for extended periods of time to avoid

transmission overheating.



Do not shift the transmission unless the engine

has returned to idle and wheels have stopped.

Make a practice of stepping on the brake pedal

while shifting the transmission.

DO NOT flat tow this vehicle. Damage to the

drivetrain will result.
Recreational towing (for two-wheel drive models) is

allowed ONLY if the rear wheels are OFF the

ground. This may be accomplished using a tow

dolly or vehicle trailer. If using a tow dolly, follow

this procedure:
1. Properly secure the dolly to the tow vehicle,

following the dolly manufacturer's

instructions.

2. Drive the rear wheels onto the tow dolly.
3. Firmly apply the parking brake. Place

automatic transmission in PARK.

4. Properly secure the rear wheels to the dolly,

following the dolly manufacturer's instructions.

5. Turn the ignition to the OFF position and

remove the key fob.

NOTE:

Both the manual shift and electronically shifted

transfer cases must be shifted into N (Neutral) for

recreational towing. Automatic transmissions must

be shifted into PARK for recreational towing. Refer

to the following for the proper transfer case N

(Neutral) shifting procedure for your vehicle.

Shifting Into N (Neutral)

Use the following procedure to prepare your

vehicle for recreational towing.

1. Bring the vehicle to a complete stop on level

ground, with the engine running. Firmly apply

the parking brake.

2. Shift the transmission to NEUTRAL.
3. Press and hold the brake pedal.

CAUTION!



DO NOT dolly tow any four-wheel drive vehicle.

Towing with only one set of wheels on the

ground (front or rear) will cause severe trans

-

mission and/or transfer case damage. Tow

with all four wheels either ON the ground, or

OFF the ground (using a vehicle trailer).



Tow only in the forward direction. Towing this

vehicle backwards can cause severe damage

to the transfer case.



Before recreational towing, the transfer case

must be in N (Neutral). To be certain the

transfer case is fully in N (Neutral), perform

the procedure outlined under “Shifting Into N

(Neutral)”. Internal transmission damage will

result, if the transfer case is not in N (Neutral)

during towing.



The transmission must be placed in PARK for

recreational towing.



Towing this vehicle in violation of the above

requirements can cause severe transmission

and/or transfer case damage. Damage from

improper towing is not covered under the New

Vehicle Limited Warranty.



Do not disconnect the rear driveshaft because

fluid will leak from the transfer case, causing

damage to internal parts.



Do not use a bumper-mounted clamp-on tow

bar on your vehicle. The bumper face bar will

be damaged.

CAUTION!

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. 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.
