LUID

Your vehicle is equipped with a Selective Catalytic

Reduction (SCR) system to meet the very stringent

diesel emissions standards required by the

Environmental Protection Agency.
The purpose of the SCR system is to reduce levels

of NOx (oxides of nitrogen emitted from engines)

that are harmful to our health and the environment

to a near-zero level. A small quantity of Diesel

Exhaust Fluid (DEF) is injected into the exhaust

upstream of a catalyst where, when vaporized, it

converts smog-forming nitrogen oxides (NOx) into

harmless nitrogen (N2) and water vapor (H2O), two

natural components of the air we breathe. You can

operate with the comfort that your vehicle is

contributing to a cleaner, healthier world

environment for this and generations to come.

System Overview

This vehicle is equipped with a Diesel Exhaust Fluid

(DEF) injection system and a Selective Catalytic

Reduction (SCR) catalyst to meet the emission

requirements.
The DEF injection system consists of the following

components:



DEF tank



DEF pump



DEF injector



Electronically-heated DEF lines



DEF control module



NOx sensors



Temperature sensors



SCR catalyst



UQS Sensor

For system messages and warnings

Ú

page 103.

NOTE:



Your vehicle is equipped with a DEF injection

system. You may occasionally hear an audible

clicking noise. This is normal operation.



The DEF pump will run for a period of time after

engine shutdown to purge the DEF system. This

is normal operation.

Diesel Exhaust Fluid Storage

Diesel Exhaust Fluid (DEF) is considered a very

stable product with a long shelf life. If DEF is kept

in temperatures between 10°F and 90°F (-12°C

and 32°C), it will last a minimum of one year.
DEF is subject to freezing at the lowest

temperatures. For example, DEF may freeze at

temperatures at or below 12°F (-11°C). The

system has been designed to operate in this

environment.

WARNING!



Never have any smoking materials lit in or

near the vehicle when the fuel door is open or

the tank is being filled.



Never add fuel when the engine is running.

This is in violation of most state and federal

fire regulations and may cause the Malfunc

-

tion Indicator Light to turn on.



A fire may result if fuel is pumped into a

portable container that is inside of a vehicle.

You could be burned. Always place fuel

containers on the ground while filling.

CAUTION!

To avoid fuel spillage and overfilling, do not “top

off” the fuel tank after filling.

STARTING AND OPERATING

211

NOTE:

When working with DEF, it is important to know

that:



Any containers or parts that come into contact

with DEF must be DEF compatible (plastic or

stainless steel). Copper, brass, aluminum, iron

or non-stainless steel should be avoided as they

are subject to corrosion by DEF.



If DEF is spilled, it should be wiped up

completely.

Adding Diesel Exhaust Fluid

The DEF gauge (located on the instrument cluster)

will display the level of DEF remaining in the tank

Ú

page 103.

NOTE:



Driving conditions (altitude, vehicle speed, load,

etc.) will affect the amount of DEF that is used in

your vehicle.



Another factor is that outside temperature can

affect DEF consumption. In cold conditions,

12°F (-11°C) and below, the DEF gauge needle

can stay on a fixed position and may not move

for extended periods of time. This is a normal

function of the system.



There is an electric heater inside the DEF tank

that automatically works when necessary. If the

DEF supply does freeze, the truck will operate

normally until it thaws.

DEF FILL PROCEDURE

NOTE:

For the correct fluid type

Ú

page 439.

Remove cap from DEF tank (located on drivers side

of the vehicle or in fuel door).

Fill Locations

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 12°F (-11°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.

(Continued)

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 103 fill the DEF tank

with no more than 4 gallons (15 liters).

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

front and rear GAWR are not exceeded.

P

AYLOAD

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.

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.



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 replace

ment. 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.

(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

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.

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.

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.

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 212.

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.

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 212.

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 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

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.

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.

1. Position the truck to be ready to connect to

the trailer (do not connect the trailer).

NOTE:

Normal Ride Height (NRH) or Alternate Trailer

Height (ATH) can be used. The vehicle must remain

in the engine running position while attaching a

trailer for proper leveling of the air suspension

system. It may not be possible to enter Alternate

Trailer Height (ATH) while lightly loaded.
2. Measure the height from the top of the front

wheel opening on the fender to the ground,

this is height H1.

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 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

factory-installed options or dealer-installed options

must be considered as part of the total load on

your vehicle. For the maximum combined weight of

occupants and cargo for your vehicle

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 362. When towing a trailer,

never exceed the GAWR or GCWR ratings.

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

Ú

page 410.



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

Ú

page 410.



For the proper tire replacement procedures

Ú

page 410. Replacing tires with a higher load

carrying capacity will not increase the vehicle's

GVWR and GAWR limits.

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.

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.



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

STARTING AND OPERATING

219



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).

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 Disconnected Warning Light will not

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

ITBM, the Trailer Brake Disconnected Warning

Light will flash.

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.
