DEF FILL PROCEDURE
NOTE:
For the correct fluid type Ú 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
Úpage 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.

22_DPF_OM_EN_USC_t.book Page 171

172STARTING 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.
VEHICLE LOADING
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.
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 does 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.

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!

178STARTING 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 Úpage 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.

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

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
(30–40 km/h).

TOWING TIPS
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.
