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 89 fill the DEF tank with
no more than 6 gal (22 L).
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 gal (7.5 L) 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.
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 gal (295 L) 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.

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.
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.

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).

1. Make sure the trailer brakes are in good working condition, functioning normally and
properly adjusted. See a trailer dealer if
necessary.

2. Hook up the trailer and make the electrical connections according to the trailer
manufacturer's instructions.
3. When a trailer with electric/EOH brakes is plugged in, the trailer connected message
should appear in the instrument cluster
display (if the connection is not recognized by the ITBM, braking functions will not be
available), the GAIN setting will illuminate and
the correct type of trailer must be selected
from the instrument cluster display options.
4. Push the UP or DOWN button on the steering wheel until “TRAILER TOW” appears on the
screen.
5. Push the RIGHT arrow on the steering wheel to enter “TRAILER TOW”.
6. Push the UP or DOWN buttons until the Trailer Brake Type appears on the screen.
7. Push the RIGHT arrow and then push the UP or DOWN buttons until the proper Trailer Brake
Type appears on the screen. 8. In a traffic-free environment, tow the trailer on
a dry, level surface at a speed of 20–25 mph
(30–40 km/h) and squeeze the manual brake
control lever completely.
9. If the trailer wheels lockup (indicated by squealing tires), reduce the GAIN setting; if the
trailer wheels turn freely, increase the GAIN
setting.
Repeat steps 8 and 9 until the GAIN setting is at a
point just below trailer wheel lockup. If towing a
heavier trailer, trailer wheel lockup may not be
attainable even with the maximum GAIN setting
of 10.
* The suggested selection depends and may change depending on the customer preferences for braking performance. Condition of the trailer brakes, driving
and road state may also affect the selection.

Towing Requirements — Trailer Lights And
Wiring
Whenever you pull a trailer, regardless of the trailer
size, stoplights and turn signals on the trailer are
required for motoring safety.
The Trailer Tow Package may include a four- and
seven-pin wiring harness. Use a factory approved
trailer harness and connector.
NOTE:Do not cut or splice wiring into the vehicle’s wiring
harness.
The electrical connections are all complete to the
vehicle but you must mate the harness to a trailer
connector. Refer to the following illustrations.
NOTE:
Disconnect the trailer wiring connector from the
vehicle (or any other device plugged into
vehicle’s electrical connectors) before
launching a boat into water.
Be sure to reconnect once clear from water
area.
