STARTING AND OPERATING195
The system may then instruct the driver to wait for 
steering to complete before then instructing to 
check surroundings and move backward.
Move Backward Into Parallel Parking Space
Move Backward Into Perpendicular Parking Space
 The system may instruct several more gear shifts 
(DRIVE and REVERSE), with hands off of the 
steering wheel, before instructing the driver to 
check surroundings and complete the parking 
maneuver.
When the vehicle is in the parking position, the 
maneuver is complete and the driver will be 
instructed to check the vehicle's parking position, 
then shift the vehicle into PARK. The message 
"Active ParkSense Complete - Check Parking 
Position" will be displayed momentarily.
NOTE:
It is the driver's responsibility to use the brake 
and accelerator during the semi-automatic 
parking maneuver.
It is the driver's responsibility to use the brake 
and stop the vehicle. The driver should check 
their surroundings and be prepared to stop the 
vehicle either when instructed to, or when driver 
intervention is required.
When the system instructs the driver to remove 
their hands from the steering wheel, the driver 
should check their surroundings and begin to 
back up slowly.
The ParkSense Active Park Assist system will 
allow a maximum of eight shifts between DRIVE 
and REVERSE. If the maneuver cannot be 
completed within eight shifts, the system will 
cancel and the instrument cluster display will 
instruct the driver to complete the maneuver 
manually.
The system will cancel the maneuver if the 
vehicle speed exceeds 5 mph (7 km/h) during 
active steering guidance into the parking space. 
The system will provide a warning to the driver 
at 3 mph (5 km/h) that tells them to slow down. 
The driver is then responsible for completing the 
maneuver if the system is canceled.
If the system is canceled during the maneuver 
for any reason, the driver must take control of 
the vehicle.

196STARTING AND OPERATING  
LANESENSE — IF EQUIPPED 
LANESENSE OPERATION
The LaneSense system is operational at speeds 
above 37 mph (60 km/h) and below 112 mph 
(180 km/h). The LaneSense system uses a 
forward looking camera to detect lane markings 
and measure vehicle position within the lane 
boundaries.
When both lane markings are detected and the 
driver drifts out of the lane (no turn signal applied), 
the LaneSense system provides a haptic warning 
in the form of torque applied to the steering wheel, 
as well as a visual warning in the instrument 
cluster display, to prompt the driver to remain 
within the lane boundaries.
The driver may manually override the haptic 
warning by applying force into the steering wheel at 
any time.
When only a single lane marking is detected and 
the driver drifts across the lane marking (no turn 
signal applied), the LaneSense system provides a 
visual warning through the instrument cluster 
display to prompt the driver to remain within the 
lane.
When only a single lane marking is detected, a 
haptic or a torque warning will not be provided.
NOTE:
When operating conditions have been met, the 
LaneSense system will monitor if the driver’s 
hands are on the steering wheel and provide an 
audible and visual warning to the driver if 
removed. The system will cancel if the driver 
does not return their hands to the wheel.
LaneSense will disable when a snow plow is 
connected to the vehicle.
TURNING LANESENSE ON OR OFF
The LaneSense button is located on the 
switch panel below the Uconnect display.
NOTE:If your vehicle is equipped with a 12-inch Uconnect 
Display screen, the LaneSense button is located 
above the display.
To turn the LaneSense system on, push the 
LaneSense button (LED turns off). A “LaneSense 
On” message is shown in the instrument cluster 
display.
To turn the LaneSense system off, push the 
LaneSense button again (LED turns on).
NOTE:The LaneSense system will retain the last system 
state on or off from the last ignition cycle when the 
ignition is placed in the ON/RUN position.
WARNING!
Drivers must be careful when performing 
parallel or perpendicular parking maneuvers 
even when using the ParkSense Active Park 
Assist system. Always check carefully behind 
and in front of your vehicle, look behind and in 
front of you, and be sure to check for 
pedestrians, animals, other vehicles, 
obstructions, and blind spots before backing up 
and moving forward. You are responsible for 
safety and must continue to pay attention to 
your surroundings. Failure to do so can result in 
serious injury or death.
CAUTION!
The ParkSense Active Park Assist system is 
only a parking aid and it is unable to recognize 
every obstacle, including small obstacles. 
Parking curbs might be temporarily detected 
or not detected at all. Obstacles located above 
or below the sensors’ field of view will not be 
detected when they are in close proximity.
The vehicle must be driven slowly when using 
the ParkSense Active Park Assist system in 
order to be able to stop in time when an 
obstacle is detected. It is recommended that 
the driver looks over his/her shoulders when 
using the ParkSense Active Park Assist system.

LANESENSE WARNING MESSAGE
The LaneSense system will indicate the current 
lane drift condition through the instrument cluster 
display.
When the LaneSense system is on, the lane lines 
are gray when both of the lane boundaries have 
not been detected and the LaneSense telltale   
is solid white.
System ON (Gray Lines) With White Telltale 
Left Lane Departure — Only Left Lane Detected  
When the LaneSense system is on, the Lane-
Sense Telltale   is solid white when only the 
left lane marking has been detected and the 
system is ready to provide visual warnings in the  instrument cluster display if an unintentional 
lane departure occurs on the left side.
When the LaneSense system senses the lane 
has been approached and is in a lane departure 
situation, the visual warning in the instrument 
cluster display will show the left lane line 
flashing yellow (on/off). The LaneSense telltale 
 changes from solid white to flashing yellow.
Lane Approached (Flashing Yellow Lane Line)  With Yellow Telltale 
NOTE:The LaneSense system operates with similar 
behavior for a right lane departure when only the 
right lane marking has been detected. Left Lane Departure — Both Lane Lines Detected
 
When the LaneSense system is on and both the 
lane markings have been detected, the system 
is "armed" to provide visual warnings in the 
instrument cluster display and a torque warning 
in the steering wheel if an unintentional lane 
departure occurs. The lane lines turn from gray 
to white and the LaneSense telltale   is solid 
green.

BULK FUEL STORAGE — DIESEL FUEL
If you store quantities of fuel, good maintenance of 
the stored fuel is also essential. Fuel contaminated 
with water will promote the growth of “microbes.” 
These microbes form “slime” that will clog the fuel 
filtration system and lines. Drain condensation 
from the supply tank and change the line filter on 
a regular basis.
NOTE:When a diesel engine is allowed to run out of fuel, 
air is pulled into the fuel system.
If the vehicle will not start  Úpage 414.
DIESEL EXHAUST FLUID
Your vehicle is equipped with a Selective Catalytic 
Reduction (SCR) system to meet diesel emissions 
standards required by the Environmental 
Protection Agency. The purpose of the SCR system is to reduce levels 
of oxides of nitrogen (NO
x) 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, 
converts smog-forming NO
x into harmless
nitrogen (N
2) and water vapor (H2O), two natural 
components of the air we breathe.
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 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
The Diesel Exhaust Fluid (DEF) gauge (located on 
the instrument cluster) will display the level of DEF 
remaining in the tank  Ú page 110.
NOTE:
Driving conditions (altitude, vehicle speed, load, 
etc.) will effect the amount of DEF that is used in 
your vehicle.
Outside temperature can affect DEF consump -
tion. In cold conditions, 12°F (-11°C) and 
below, the DEF gauge may take longer to 
operate as intended. 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.WARNING!
Do not open the high pressure fuel system with 
the engine running. Engine operation causes 
high fuel pressure. High pressure fuel spray can 
cause serious injury or death.

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!

ADJUSTMENT
Towing With Air Suspension — If Equipped
1. Verify that the vehicle is at the normal ride 
height.
NOTE:The vehicle must remain in the engine run position 
with all doors closed while attaching a trailer for 
proper leveling of the air suspension system.
2. Position the truck to be ready to connect to the trailer (do not connect the trailer).
3. Enable tire jack mode through the instrument  cluster or touchscreen radio settings. Tire jack 
mode will be canceled and the procedure must 
be restarted if the vehicle is driven at speeds 
above 5 mph (8 km/h).
4. Measure the height from the top of the front  wheel opening on the fender to ground; this is 
height H1.
 Measuring Height (H)
5. Attach the trailer to the vehicle without the  weight-distributing bars connected.
6. Measure the height from the top of the front  wheel opening on the fender to the ground; 
this is height H2.
7. Install and adjust the tension in the  weight-distributing bars per the 
manufacturer’s recommendations so that the 
height of the front fender is approximately 
(H2-H1)/3+H1 (about 1/3 the difference 
between H2 and H1 above normal ride height 
[H1]). 8. Use the instrument cluster or touchscreen 
radio settings and switch off tire jack mode. 
Make sure the truck returns to normal ride 
height. Perform a visual inspection of the 
trailer and weight-distributing hitch to confirm 
the manufacturer’s recommendations have 
been met.
9. The truck can now be driven.

TRAILER REVERSE STEERING CONTROL
Feature Overview
Trailer Reverse Steering Control (TRSC) is a feature 
that will assist the driver when backing up a trailer. 
By turning the knob located on the center stack, 
you can more accurately control the direction the 
trailer will go.
The driver controls the accelerator and the brake 
while steering with the use of the Trailer Reverse 
Steering Control knob. The trailer is steered 
according to the direction the knob is turned. This feature will also allow the driver to back up a 
vehicle and trailer in a straight line when the knob 
is rested in its center position.
Minimal setup is required to use this feature.
Set Up:
To use the system, hitch your trailer to the truck 
and ensure all electrical wiring is connected  
Ú
page 223.
The system will automatically calibrate an 
attached trailer during normal forward driving with 
no additional action needed from the driver. If the 
vehicle has not had enough time to automatically 
calibrate after connecting a trailer, you will see a 
“Calibrate Trailer” message in the instrument 
cluster when pressing the TRSC button to activate 
the system. If this is the case, perform the following 
maneuver to calibrate the trailer:
Drive forward at least 100 ft (30 m), perform a 
90 degree turn and return to a straight position for 
at least another 100 ft (30 m). Perform another  90 degree turn, followed by another straight drive 
of at least 100 ft (30 m). Check that the system has calibrated by pushing the TRSC button.

Trailer Reverse Steering Control Calibration
 Using TRSC
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.
