for more information. The speed increment
shown is dependent on the selected speed
unit of U.S. (mph) or Metric (km/h):
U.S. Speed (mph)
• Pushing the SET (-) button once will resultin a 1 mph decrease in set speed. Each
subsequent tap of the button results in a
decrease of 1 mph.
• If the button is continually pushed, the set speed will continue to decrease until the
button is released, then the new set speed
will be established.
Metric Speed (km/h)
• Pushing the SET (-) button once will result in a 1 km/h decrease in set speed. Each
subsequent tap of the button results in a
decrease of 1 km/h.
• If the button is continually pushed, the set speed will continue to decrease until the
button is released, then the new set speed
will be established.To Accelerate For Passing
Press the accelerator as you would normally.
When the pedal is released, the vehicle will
return to the set speed.
Using Speed Control On Hills
The transmission may downshift on hills to
maintain the vehicle set speed.
NOTE:
The Speed Control system maintains speed
up and down hills. A slight speed change on
moderate hills is normal.
On steep hills, a greater speed loss or gain
may occur so it may be preferable to drive
without Speed Control.
WARNING!
Speed Control can be dangerous where the
system cannot maintain a constant speed.
Your vehicle could go too fast for the con-
ditions, and you could lose control and
have an accident. Do not use Speed Con-
trol in heavy traffic or on roads that are
winding, icy, snow-covered or slippery.
To Resume Speed
To resume a previously set speed, push the
RES (+) button and release. Resume can be
used at any speed above 20 mph (32 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the
CANCEL button, or normal brake pressure
while slowing the vehicle will deactivate the
Speed Control without erasing the set speed
from memory.
Pushing the ON/OFF button or turning the
ignition switch OFF erases the set speed from
memory.

PARKSENSE FRONT AND REAR PARK
ASSIST — IF EQUIPPED
The ParkSense Park Assist system provides
visual and audible indications of the distance
between the rear and/or front fascia and a
detected obstacle when backing up or mov-
ing forward, e.g. during a parking maneuver.
Refer to “ParkSense System Usage
Precautions” in the Owner’s Manual at
www.mopar.com/en-us/care/
owners-manual.html (U.S. Residents) or
www.owners.mopar.ca (Canadian Residents)
for limitations of this system and recommen-
dations.
ParkSense will retain the last system state
(enabled or disabled) from the last ignition
cycle when the ignition is changed to the
ON/RUN position.
ParkSense can be active only when the gear
selector is in REVERSE or DRIVE. If
ParkSense is enabled at one of these gear
selector positions, the system will remain
active until the vehicle speed is increased to
approximately 7 mph (11 km/h) or above. A
warning will appear in the instrument clusterdisplay indicating the vehicle is above
ParkSense operating speed. The system will
become active again if the vehicle speed is
decreased to speeds less than approximately
6 mph (9 km/h).
ParkSense Sensors
For the 3500, 4500 and 5500 Chassis Cab
vehicles, the rear ParkSense sensors are
shipped loose. Please refer to the Ram Body
Builders Guide for more information.
Cleaning The ParkSense System
Clean the ParkSense sensors with water, car
wash soap and a soft cloth. Do not use rough
or hard cloths. Do not scratch or poke the
sensors. Otherwise, you could damage the
sensors.
PARKVIEW REAR BACK UP CAMERA
— IF EQUIPPED
Your vehicle may be equipped with the
ParkView Rear Back Up Camera that allows
you to see a image of the rear surroundings of
your vehicle whenever the gear selector is put
into REVERSE or whenever it is initiated through the "Backup Camera" button in the
"Controls" menu. Whenever the gear selector
is put into REVERSE, the image will be
displayed in the rearview mirror display (if
equipped) or Uconnect screen (if equipped)
along with a caution note to “check entire
surroundings” across the top of the screen.
After five seconds this note will disappear.
NOTE:
For the 3500, 4500 and 5500 Chassis Cab
vehicles, the Rear Backup Camera is shipped
loose and not installed. Please refer to the
Ram Body Builders Guide for more informa-
tion.
The ParkView Camera is located to the left of
the tailgate handle.
When the vehicle is shifted out of REVERSE
(with Camera delay turned off), the rear Cam-
era mode is exited and the navigation or
audio screen appears again.
When the vehicle is shifted out of REVERSE
(with Camera delay turned on), the rear Cam-
era image will be displayed for up to 10 sec-
onds after shifting out of REVERSE unless
STARTING AND OPERATING

the forward vehicle speed exceeds 8 mph
(13 km/h), the transmission is shifted into
PARK or the ignition is switched to the OFF
position.
Whenever the Rear View Camera image is
activated through the "Backup Camera" but-
ton in the "Controls" menu, a display timer for
the image is initiated. The image will con-
tinue to be displayed until the display timer
exceeds 10 seconds and the vehicle speed is
above 8 mph (13 km/h) or the touchscreen
button "X" to disable display of the Rear View
Camera image is pressed.
NOTE:
If the vehicle speed remains below 8 mph
(13 km/h), the Rear View Camera image will
be displayed continuously until deactivated
via the touchscreen button "X".
If equipped with a Cargo Camera, a touch-
screen button
to indicate the current
active Camera image being displayed is made
available whenever the Rear View Camera
image is displayed. If equipped with a Cargo Camera, a touch-
screen button
to switch the display to
Cargo Camera image is made available when-
ever the Rear View Camera image is dis-
played.
A touchscreen button "X" to disable display of
the camera image is made available when the
vehicle is not in REVERSE gear.
When enabled, active guide lines are overlaid
on the image to illustrate the width of the
vehicle and its projected backup path based
on the steering wheel position. The active
guide lines will show separate zones that will
help indicate the distance to the rear of the
vehicle.
NOTE:

for further information.WARNING!
Drivers must be careful when backing up
even when using the ParkView Rear Back
Up Camera. Always check carefully behind
your vehicle, and be sure to check for
pedestrians, animals, other vehicles, ob-
structions, or blind spots before backing
up. You are responsible for the safety of
your surroundings and must continue to
pay attention while backing up. Failure to
do so can result in serious injury or death.
CAUTION!
• To avoid vehicle damage, ParkView should only be used as a parking aid.
The ParkView camera is unable to view
every obstacle or object in your drive
path.
• To avoid vehicle damage, the vehicle
must be driven slowly when using
ParkView to be able to stop in time when
an obstacle is seen. It is recommended
that the driver look frequently over his/
her shoulder when using ParkView.

REFUELING THE VEHICLE — GAS
CAUTION!
• Damage to the fuel system or emissions control system could result from using
an improper fuel tank filler tube cap
(fuel filler cap). A poorly fitting cap
could let impurities into the fuel system.
Also, a poorly-fitted aftermarket cap can
cause the MIL (Malfunction Indicator
Light) to illuminate due to fuel vapors
escaping from the system.
• A poorly fitting fuel filler cap may cause
the MIL to turn on.
• To avoid fuel spillage and overfilling, do
not “top off” the fuel tank after filling.
NOTE:
When the fuel nozzle “clicks” or shuts off the
fuel tank is full.
WARNING!
• Never have any smoking materials lit in or near the vehicle when the gas cap is
removed or the tank is being filled.
• Never add fuel to the vehicle when the
engine is running. This is in violation of
most state and federal fire regulations
and may cause the MIL to turn on.
NOTE:
Tighten the gas cap ¼ turn until you hear one
click. This is an indication that the cap is
properly tightened.
If the gas cap is not tightened properly, the
Malfunction Indicator Light will come on. Be
sure the gas cap is tightened every time the
vehicle is refueled.
WARNING!
A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place gas con-
tainers on the ground while filling.

Materials Added To Fuel
Designated TOP TIER
Detergent Gasoline
contains a higher level
of detergents to further
aide in minimizing en-
gine and fuel system
deposits. When avail-
able, the usage of Top
Tier Detergent gasoline is recommended.
Visit www.toptiergas.com for a list of TOP
TIER Detergent Gasoline Retailers.
Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these
materials intended for gum and varnish re-
moval may contain active solvents or similar
ingredients. These can harm fuel system gas-
ket and diaphragm materials.
REFUELING THE VEHICLE — DIESEL
CHASSIS CAB MODELS
CAUTION!
To avoid fuel spillage and overfilling, do
not “top off” the fuel tank after filling.
NOTE:
• When the fuel nozzle “clicks” or shuts off, the fuel tank is full.
• Tighten the fuel filler cap until you hear a “clicking” sound. This is an indication that
the fuel filler cap is properly tightened.
• Make sure that the fuel filler cap is tight- ened each time the vehicle is refueled.
WARNING!
A fire may result if gasoline is pumped into
a portable container that is inside of a
vehicle. You could be burned. Always
place gas containers on the ground while
filling.
Diesel Exhaust Fluid
Your vehicle is equipped with a Selective
Catalytic Reduction 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. Small
quantities of Diesel Exhaust Fluid (DEF) is
injected into the exhaust upstream of a cata-
lyst 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 Ex-
haust Fluid (DEF) injection system and a
Selective Catalytic Reduction (SCR) catalyst
to meet the emission requirements.
139

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
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
system messages and warnings.
NOTE:
• Your vehicle is equipped with a DEF injec-tion system. You may occasionally hear an
audible clicking noise. This is normal op-
eration.
• 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 tem-
peratures. 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 con-tact 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 DEF gauge (located on the instrument
cluster) will display the level of DEF remain-
ing in the tank. Refer to “Instrument Cluster”
and “Instrument Cluster Descriptions” in
“Getting To Know Your Instrument Panel” for
further information.
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 con-
ditions, 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 sys-
tem.
• There is an electric heater inside the DEF tank that automatically works when neces-
sary. And if the DEF supply does freeze, the
truck will operate normally until it thaws.

DEF Fill Procedure
NOTE:
Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for the correct fluid type.
1. Remove cap from DEF tank (located ondrivers side of the vehicle or in fuel door). 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 Diesel Exhaust Fluid (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
your authorized dealer for service.
• The DEF gauge may also not immedi- ately update after a refill if the tempera-
ture of the DEF fluid is below 12F
(-11C). The DEF line heater will possi-
bly 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.
CAUTION!
•To avoid DEF spillage, and possible dam-
age to the DEF tank from overfilling, do
not “top off” the DEF tank after filling.
• DO NOT OVERFILL. DEF will freeze be- low 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 immediately with water and use an ab-
sorbent material 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 dam-
age to your engine, including but not
limited to failure of the fuel pump and
injectors.

CAUTION!
• Never add anything other than DEF tothe tank – especially any form of hydro-
carbon 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 contami-
nate 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 is has only been used for adding
DEF. Mopar provides an attachable
nozzle with its DEF for this purpose.
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
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.
