ENGINE RUNAWAY

Diesel engine runaway is a rare condition

affecting diesel engines, where the engine

consumes its own lubrication oil and runs at

higher and higher RPM until it overspeeds to

a point where it destroys itself due to either

mechanical failure or engine seizure through

lack of lubrication.

REFUELING THE VEHICLE — GASOLINE

ENGINE

NOTE:

When the fuel nozzle “clicks” or shuts off the

fuel tank is full.

NOTE:

Tighten the gas cap a quarter turn until you hear

one click. This is an indication that the cap is

properly tightened.

If the gas cap is not tightened properly, the

Malfunction Indicator Light will come on.

Be sure the gas cap is tightened every time the

vehicle is refueled.

WARNING!

In case of engine runaway due to flammable

fumes from fuel spills or turbocharger oil

leaks being sucked into the engine, do the

following to help avoid personal injury and/or

vehicle damage:



Turn the ignition switch to the OFF position.



Using a CO2 or dry chemical type fire extin

-

guisher, direct the spray from the fire extin

-

guisher into the grille on the passenger side so

that the spray enters the engine air intake.

The inlet for the engine air intake is located

behind the passenger side headlamp and

receives air through the grille.

CAUTION!



Damage to the fuel system or emissions

control system could result from using an

improper fuel tank filler tube cap (fuel filler

cap). A poorly fitting cap could let impurities

into the fuel system. Also, a poorly-fitted

aftermarket cap can cause the MIL

(Malfunction Indicator Light) to illuminate

due to fuel vapors escaping from the

system.



A poorly fitting fuel filler cap may cause the

MIL to turn on.



To avoid fuel spillage and overfilling, do not

“top off” the fuel tank after filling.

WARNING!



Never have any smoking materials lit in

or near the vehicle when the gas cap is

removed or the tank is being filled.



Never add fuel to the vehicle when the

engine is running. This is in violation of

most state and federal fire regulations and

may cause the MIL to turn on.

WARNING!

A fire may result if gasoline is pumped into a

portable container that is inside of a vehicle.

You could be burned. Always place gas

containers on the ground while filling.

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

page 90.

CAUTION!

To avoid fuel spillage and overfilling, do not

“top off” the fuel tank after filling.

WARNING!

A fire may result if gasoline is pumped into a

portable container that is inside of a vehicle.

You could be burned. Always place gas

containers on the ground while filling.

STARTING AND OPERATING

197

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° and 90°F (-12°

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.

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 (DEF)

The DEF gauge (located on the instrument

cluster) will display the level of DEF remaining in

the tank

Ú

page 90.

NOTE:



Driving conditions (altitude, vehicle speed,

load, etc.) will effect the amount of DEF that

is used in your vehicle.



Another factor is that outside temperature

can affect DEF consumption. In cold condi

-

tions, 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 neces

-

sary. And if the DEF supply does freeze, the

truck will operate normally until it thaws.

DEF Fill Procedure

NOTE:

For the correct fluid type

NOTE:



The DEF gauge may take up to five seconds

to update after adding a gallon or more of

Diesel Exhaust Fluid (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 prop

-

erly and is just updating with proper thawed

DEF.



Excessive overfilling of the DEF tank can

result in a MIL lamp/fault code and inaccu

-

rate level readings.

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 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 instru

-

ment panel display

Ú

page 90 fill the DEF

tank with no more than 6 Gallons (22 liters).

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 over

-

filled and freezes, the system could be

damaged.



When DEF is spilled, clean the area imme

-

diately 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

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.

STARTING AND OPERATING

199

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

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.

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.



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 contam

-

inate 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 is 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 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 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.

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. Also

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 199.

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 199.

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.

WARNING!

If the gross trailer weight is 5,000 lbs

(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.
