Diesel Exhaust Fluid (DEF) Fill Procedure
NOTE:
For the correct fluid type  Úpage 473.
1. Remove cap from Diesel Exhaust Fluid (DEF)  tank which is located next to the diesel fuel 
filler.
DEF Filler Cap And Fuel Fill
 2. Insert DEF fill adapter/nozzle into DEF tank 
filler neck.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 autho -
rized 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 
line heater will possibly warm up the DEF 
fluid and allow the gauge to update after a 
period of run time. Under very cold condi -
tions, it is possible that the gauge may not 
reflect the new fill level for several drives.
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.
If systems which cannot be screwed in
(e.g. tanks) are used for refilling, after the 
indication appears on the instrument panel 
display   Úpage 114 fill the DEF tank with no 
more than 2 gallons (8 liters).
If containers which can be screwed to the 
filler are used, the reservoir is full when the 
DEF level in the container stops pouring out. 
Do not proceed further.

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.
22_DT_OM_EN_USC_t.book  Page 210   

STARTING AND OPERATING211
3. Stop filling the DEF tank immediately when any  of the following happen: DEF stops flowing 
from the fill bottle into the DEF tank, DEF 
splashes out the filler neck, or a DEF pump 
nozzle automatically shuts off.
4. Reinstall cap onto DEF tank.
Filling The Def Tank In Cold Climates
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. Do not overfill the DEF tank. If the tank is 
overfilled and freezes, it could be damaged.
Extra care should be taken when filling with 
portable containers to avoid overfilling. Keep an 
eye on the DEF gauge in your instrument cluster. 
You may safely add a maximum of 2 gallons
(7.6 Liters) when your DEF gauge is reading at 
the half mark.
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 Gross Axle 
Weight Rating (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.
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.
CAUTION!

Trailer Reverse Steering Control Knob
To use the system, place the gear selector in PARK 
and put your foot on the brake. Push the activation 
button located above the TRSC knob in the center 
stack. The LED on the button will glow solid and the 
instrument cluster display will direct you to shift to 
REVERSE. Once in REVERSE the system is active. 
Remove hands from the steering wheel and slowly 
back up while turning the TRSC knob in the  direction you want the trailer to go. Turning the 
knob clockwise will cause the trailer to turn right. 
Turning the knob counterclockwise will cause the 
trailer to turn left. If you release the knob, it will 
return to its center position, and the trailer will 
back up in a straight line.
Continue to control the accelerator and brake 
while backing the trailer up.
NOTE:While active, TRSC will automatically disable the 
Rear Park Assist system if it was previously 
enabled.
The system will limit the top speed your vehicle can 
travel in REVERSE while using the feature. If 
needed, you can shift to DRIVE or NEUTRAL to pull 
forward to get more room or straighten out the 
trailer, and shift back to REVERSE without the need 
to reactivate the feature.
The feature will cancel after 30 seconds in 
DRIVE or when the vehicle speed reaches 8 mph 
(12 km/h).
To cancel out of the feature, come to a stop and 
shift to PARK, or push the TRSC activation button.

Trailer Memory
The trailer steering system will automatically retain 
the calibration of the previous five trailers 
connected, so recalibration will not be necessary 
when hooking up. The next time the vehicle is 
started, place the vehicle in DRIVE and drive a 
short distance. The TRSC system can then be 
activated.
NOTE:Trailers may look different during day and night 
conditions. In such cases, the trailer may need to 
recalibrate. Some trailers (such as boat trailers) will need to 
recalibrate while loaded and unloaded.
NOTE:
The system may not detect a trailer in low light 
conditions. In sunny conditions, the perfor
-
mance may be degraded as shadows pass over 
the trailer.
The driver is always responsible for safe opera -
tion of truck and trailer.
The driver is always in control of the truck as 
well as the trailer and is responsible for 
controlling the throttle and brakes.
The system may not function when the camera 
lens is blocked, blurred (covered with water, 
snow, ice, dirt, etc) and will not work unless the 
tailgate is upright and fully latched.
TOWING REQUIREMENTS 
To promote proper break-in of your new vehicle 
drivetrain components, the following guidelines 
are recommended.
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.

STARTING AND OPERATING221
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 EOH systems. 
Some previous EOH systems may not be 
compatible with ITBM.
Integrated Trailer Brake Module (ITBM)
 The user interface consists of the following:
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.
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.
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.

Display Messages
The trailer brake control interacts with the 
instrument cluster display. Display messages, 
along with a single chime, will be displayed 
when a malfunction is determined in the trailer 
connection, trailer brake control, or on the trailer  
Ú page 114.
NOTE:
An aftermarket controller may be available for 
use with trailers with air or EOH trailer brake 
systems. To determine the type of brakes on 
your trailer and the availability of controllers, 
check with your trailer manufacturer or dealer.
Removal of the ITBM will cause errors and it 
may cause damage to the electrical system and 
electronic modules of the vehicle. See an autho -
rized dealer if an aftermarket module is to be 
installed.
Towing Requirements — Trailer Lights And 
Wiring
Whenever you pull a trailer, regardless of the trailer 
size, stop lights and turn signals on the trailer are 
required for motoring safety.
The Trailer Tow Package may include a four-pin 
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 connect the harness to a 
trailer connector. Refer to the following 
illustrations.
NOTE:
Disconnect trailer wiring connector from the 
vehicle before launching a boat (or any other 
device plugged into vehicle’s electrical connect) 
into water.
Be sure to reconnect once clear from water 
area.
Four-Pin Connector
WARNING!
Connecting a trailer that is not compatible with 
the ITBM system may result in reduced or 
complete loss of trailer braking. There may be a 
increase in stopping distance or trailer instability 
which could result in personal injury.
CAUTION!
Connecting a trailer that is not compatible with 
the ITBM system may result in reduced or 
complete loss of trailer braking. There may be a

STARTING AND OPERATING225
TOWING TIPS 
Before towing, 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.
Tow/Haul Mode
To reduce potential for automatic transmission 
overheating, activate TOW/HAUL mode when 
driving in hilly areas, or select a lower gear range 
(using the (ERS) shift control) on more severe 
grades.
Cruise Control — If Equipped
Do not use on hilly terrain or with heavy loads.
When using the Cruise Control, if you experience 
speed drops greater than 10 mph (16 km/h), 
disengage until you can get back to cruising 
speed.
Use Cruise Control in flat terrain and with light 
loads to maximize fuel efficiency.
Air Suspension System
To aid in attaching/detaching the trailer from the 
vehicle, the air suspension system can be used  
Úpage 165. Selecting Tow/Haul or connecting a 
trailer with an Integrated Trailer Brake Module 
(ITBM) will disable Automatic Aero mode to avoid 
height changes while towing and shifting loads or 
tongue weights.
NOTE:The vehicle must remain in the engine running 
position while attaching a trailer for proper leveling 
of the air suspension system.
SNOWPLOW
Snowplow Prep Packages are available as a factory 
installed option. These packages include 
components necessary to equip your vehicle with a 
snowplow.
NOTE:Before installation of a snowplow it is highly recom -
mended that the owner/installer obtain and follow 
the recommendations contained within the current 
Body Builder’s Guide. See an authorized dealer, 
installer or snowplow manufacturer for this infor -
mation. There are unique electrical systems that 
must be connected to properly ensure operator 
safety and prevent overloading vehicle systems.
WARNING!
Attaching a snowplow to this vehicle could 
adversely affect performance of the airbag 
system in a collision. Do not expect that the 
airbag will perform as described earlier in this 
manual.
CAUTION!
The “Lamp Out” indicator could illuminate if 
exterior lamps are not properly installed.
