170STARTING AND OPERATING
DIESEL EXHAUST FLUID
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 81.
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
Úpage 81.
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 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.

STARTING AND OPERATING173
LOADING
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.
COMMON TOWING DEFINITIONS
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

22_DPF_OM_EN_USC_t.book Page 173

174STARTING 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.

STARTING AND OPERATING177
(Continued)
(Continued)
TRAILER AND TONGUE WEIGHT
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 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 Úpage 380.
TOWING REQUIREMENTS
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!
