WARNING!
on the vehicle roof. Do not drill into the
roof of the vehicle for any reason.
Side Impacts
The Side Air Bags are designed to activate in
certain side impacts. The Occupant Restraint
Controller (ORC) determines whether the de-
ployment of the Side Air Bags in a particular
impact event is appropriate, based on the
severity and type of collision. The side impact
sensors aid the ORC in determining the ap-
propriate response to impact events. The
system is calibrated to deploy the Side Air
Bags on the impact side of the vehicle during
impacts that require Side Air Bag occupant
protection. In side impacts, the Side Air Bags
deploy independently; a left side impact de-
ploys the left Side Air Bags only and a right-
side impact deploys the right Side Air Bags
only. Vehicle damage by itself is not a good
indicator of whether or not Side Air Bags
should have deployed.
The Side Air Bags will not deploy in all side
collisions, including some collisions at cer-
tain angles, or some side collisions that do not impact the area of the passenger com-
partment. The Side Air Bags may deploy
during angled or offset frontal collisions
where the front air bags deploy.
Side Air Bags are a supplement to the seat
belt restraint system. Side Air Bags deploy in
less time than it takes to blink your eyes.
WARNING!
• Occupants, including children, who are
up against or very close to Side Air Bags
can be seriously injured or killed. Occu-
pants, including children, should never
lean on or sleep against the door, side
windows, or area where the side air bags
inflate, even if they are in an infant or
child restraint.
• Seat belts (and child restraints where
appropriate) are necessary for your pro-
tection in all collisions. They also help
keep you in position, away from an in-
flating Side Air Bag. To get the best
protection from the Side Air Bags, occu-
pants must wear their seat belts properly
and sit upright with their backs against
WARNING!
the seats. Children must be properly
restrained in a child restraint or booster
seat that is appropriate for the size of the
child.
WARNING!
• Side Air Bags need room to inflate. Donot lean against the door or window. Sit
upright in the center of the seat.
• Being too close to the Side Air Bags
during deployment could cause you to
be severely injured or killed.
• Relying on the Side Air Bags alone could
lead to more severe injuries in a colli-
sion. The Side Air Bags work with your
seat belt to restrain you properly. In
some collisions, Side Air Bags won’t
deploy at all. Always wear your seat belt
even though you have Side Air Bags.
NOTE:
Air bag covers may not be obvious in the
interior trim, but they will open during air bag
deployment.

Rollover Events (If Equipped With Rollover
Sensing)
Side Air Bags are designed to activate in
certain rollover events. The Occupant Re-
straint Controller (ORC) determines whether
the deployment of the Side Air Bags in a
particular rollover event is appropriate, based
on the severity and type of collision. Vehicle
damage by itself is not a good indicator of
whether or not Side Air Bags should have
deployed.
The Side Air Bags will not deploy in all
rollover events. The rollover sensing-system
determines if a rollover event may be in
progress and whether deployment is appro-
priate. A slower-developing event may deploy
the seat belt pretensioners on both sides of
the vehicle. A faster-developing event may
deploy the seat belt pretensioners as well as
the Side Air Bags on both sides of the vehicle.
The rollover sensing-system may also deploy
the seat belt pretensioners, with or without
the Side Air Bags, on both sides of the vehicle
if the vehicle experiences a near rollover
event.The SABICs may help reduce the risk of
partial or complete ejection of vehicle occu-
pants through side windows in certain roll-
over or side impact events.
Air Bag System Components
NOTE:
The Occupant Restraint Controller (ORC)
monitors the internal circuits and intercon-
necting wiring associated with electrical Air
Bag System Components listed below:
• Occupant Restraint Controller (ORC)
• Air Bag Warning Light
• Steering Wheel and Column
• Instrument Panel
• Knee Impact Bolsters
• Driver and Front Passenger Air Bags
• Seat Belt Buckle Switch
• Supplemental Side Air Bags
• Front and Side Impact Sensors — If
Equipped
• Seat Belt Pretensioners
If A Deployment Occurs
The front air bags are designed to deflate
immediately after deployment.
NOTE:
Front and/or side air bags will not deploy in all
collisions. This does not mean something is
wrong with the air bag system.
If you do have a collision which deploys the
air bags, any or all of the following may occur:
• The air bag material may sometimes cause abrasions and/or skin reddening to the oc-
cupants as the air bags deploy and unfold.
The abrasions are similar to friction rope
burns or those you might get sliding along a
carpet or gymnasium floor. They are not
caused by contact with chemicals. They are
not permanent and normally heal quickly.
However, if you haven’t healed significantly
within a few days, or if you have any blis-
tering, see your doctor immediately.
• As the air bags deflate, you may see some smoke-like particles. The particles are a
normal by-product of the process that gen-
erates the non-toxic gas used for air bag
inflation. These airborne particles may irri-
tate the skin, eyes, nose, or throat. If you

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 moving
forward, e.g. during a parking maneuver. Re-
fer to “ParkSense System Usage Precau-
tions” in the Owner’s Manual for limitations
of this system and recommendations.
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 cluster
display indicating the vehicle is aboveParkSense operating speed. The system will
become active again if the vehicle speed is
decreased to speeds less than approximately
6 mph (9 km/h).
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 dis-
played 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.
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
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.

The DEF injection system consists of the
following components:
• DEF tank
• DEF pump
• DEF injector
• Electronically-heated DEF lines
• NOx sensors
• Temperature sensors
• SCR catalyst
The DEF injection system and SCR catalyst
enable the achievement of diesel emissions
requirements; while maintaining outstanding
fuel economy, drivability, torque and power
ratings.
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 from under the ve-
hicle at a stop. This is normal operation. • The DEF pump will run for a period of time
after engine shutdown to purge the DEF
system. This is normal operation and may
be audible from the rear of the vehicle.
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 on
drivers side of the vehicle or in fuel door).

Diesel Exhaust Fluid
Your vehicle is equipped with a Selective
Catalytic Reduction system to meet the very
stringent diesel emissions standards re-
quired 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.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.

nate and an audible chime will be heard. At
this point, you should stop the engine and
drain the water from the filter housing.
CAUTION!
If the “Water In Fuel Indicator Light” re-
mains on, DO NOT START the engine be-
fore you drain water from the fuel filter to
avoid engine damage.
If the “Water In Fuel Indicator Light” comes
on and a single chime is heard while you are
driving, or with the ignition in the ON posi-
tion, there may be a problem with your water
separator wiring or sensor. See your autho-
rized dealer for service.
Upon proper draining of the water from the
fuel filter, the “Water In Fuel Indicator Light”
will remain illuminated for approximately
10 seconds. If the water was drained while
the engine was running, the “Water In Fuel
Indicator Light” may remain on for approxi-
mately three minutes. NOTE:
Care should be taken in disposing of used
fluids from your vehicle. Used fluids, indis-
criminately discarded, can present a problem
to the environment. Contact an authorized
dealer, service station, or government agency
for advice on recycling programs and for
where used fluids and filters can be properly
disposed of in your area.
Drain the fuel/water separator filter when the
“Water In Fuel Indicator Light” is ON. Within
10 minutes of vehicle shutdown, turn the
filter drain valve (located on the bottom of the
filter housing) counterclockwise to drain fuel/
water, then turn the ignition switch to the ON
position, and allow any accumulated water to
drain. Leave the drain valve open until all
water and contaminants have been removed.
When clean fuel is visible, close the drain
valve by turning it clockwise, and turn the
ignition switch to OFF.
If more than two ounces or 60 milliliters of
fuel have been drained, follow the directions
for “Priming If The Engine Has Run Out Of
Fuel.”
Underbody Mounted Fuel Filter
Replacement
NOTE:
Using a fuel filter that does not meet the
manufacturer's filtration and water separat-
ing requirements can severely impact fuel
system life and reliability.
CAUTION!
• Diesel fuel will damage blacktop paving
surfaces. Drain the filter into an appro-
priate container.
• Do not prefill the fuel filter when install-
ing a new fuel filter. There is a possibility
debris could be introduced into the fuel
filter during this action. It is best to
install the filter dry and allow the in-tank
lift pump to prime the fuel system.
1. Turn engine off.
2. Place a drain pan under the fuel filter assembly.
3. Open the water drain valve, and let any accumulated water drain.
4. Close the water drain valve.

vice kit comes with new o-ring for filter can-
ister and WIF sensor.
Priming If The Engine Has Run Out
Of Fuel
WARNING!
Do not open the high pressure fuel system
with the engine running. Engine operation
causes high fuel pressure. High pressure
WARNING!
fuel spray can cause serious injury or
death.
1. Add a substantial amount of fuel to the tank, approximately 2 to 5 gal (8L to
19L).
2. Press ignition switch twice without your foot on brake to put vehicle in Run posi-
tion. This will activate the in tank fuel
pump for approximately 30 seconds. Re-
peat this process twice.
3. Start the engine using the “Normal Start- ing” procedure. Refer to “Starting The
Engine” in “Starting and Operating” for
further information.
CAUTION!
The starter motor will engage for approxi-
mately 30 seconds at a time. Allow two
minutes between cranking intervals.
NOTE:
The engine may run rough until the air is
forced from all the fuel lines.
WARNING!
Do not use alcohol or gasoline as a fuel
blending agent. They can be unstable un-
der certain conditions and be hazardous or
explosive when mixed with diesel fuel.
CAUTION!
Due to lack of lubricants in alcohol or
gasoline, the use of these fuels can cause
damage to the fuel system.
NOTE:
• Use of biodiesel mixture in excess of 20% can negatively impact the fuel filter's abil-
ity to separate water from the fuel, resulting
in high pressure fuel system corrosion or
damage.
• In addition, commercially available fuel ad- ditives are not necessary for the proper
operation of your diesel engine.
• For extreme cold conditions, "Mopar Pre- mium Diesel Fuel Treatment" is recom-
mended to assist with cold starting.

If the vehicle experiences a sudden loss of
engine power while being driven in heavy
snow or rain, or when plowing snow, and/or
the “SERVICE AIR FILTER” message is dis-
played on the instrument cluster along with a
chime that repeats every 60 seconds, visually
inspect the air filter for snow/ice build up or
extreme water saturation. If the air filter is
not damaged, remove all snow/ice and rein-
stall air filter. If the air filter is damaged,
replace filter element.
NOTE:
The air filter housing contains a Mass Air
Flow sensor. This sensor is critical to proper
engine operation and component longevity.
Any damage or modification to this sensor
could result in major engine and/or exhaust
aftertreatment damage. We recommend you
use Mopar brand parts.
Even though your vehicle is equipped with an
Air Filter Monitor, a visual inspection of the
air cleaner filter element is recommended
every 15,000 miles (24,000km) or
12 months – whichever occurs first.Under nocircumstances should the air cleaner filter ele-
ment exceed 30,000 miles (48,000 km) or
24 months, whichever comes first.
CAUTION!
Many aftermarket performance air filter
elements do not adequately filter the air
entering the engine. Use of such filters can
severely damage your engine.
Draining Fuel/Water Separator
Filter
There are two fuel filter assemblies. One is
located on the driver's side of the engine. The
best access to this water drain valve is from
under the hood. The second one is on the
under body, located in front of the rear axle
above the drive shaft on pick-up models. The
Chassis Cab models second filter location is
on the frame behind the front axle. The best
access to this water drain valve is from under
the vehicle.
CAUTION!
• Do not drain the fuel/water separator
filter when the engine is running.
• Diesel fuel will damage blacktop paving
surfaces. Drain the filter into an appro-
priate container.
If water is detected in the water separator
while the engine is running, or while the
ignition switch is in the ON position, the
“Water In Fuel Indicator Light” will illumi-
nate and an audible chime will be heard five
times. At this point you should stop the
engine and drain the water from both of the
filters.
CAUTION!
If the “Water In Fuel Indicator Light” re-
mains on, DO NOT START the engine be-
fore you drain water from the fuel filters to
avoid engine damage.
If the “Water In Fuel Indicator Light” comes
on and a single chime is heard while you are
driving, or with the ignition switch in the ON

position, there may be a problem with your
water separator wiring or sensor. See your
authorized dealer for service.
Upon proper draining of the water from both
fuel filters, the “Water In Fuel Indicator
Light” will remain illuminated for approxi-
mately 10 seconds. If the water was drained
while the engine was running, the “Water In
Fuel Indicator Light” may remain on for ap-
proximately three minutes.
NOTE:
Care should be taken in disposing of used
fluids from your vehicle. Used fluids, indis-
criminately discarded, can present a problem
to the environment. Contact an authorized
dealer, service station, or government agency
for advice on recycling programs and for
where used fluids and filters can be properly
disposed of in your area.
Drain the fuel/water separator filters when
the “Water In Fuel Indicator Light” is ON.
Within 10 minutes of vehicle shutdown, turn
the engine mounted filter drain valve (located
on the side of the filter assembly) counter-
clockwise 1/4 turn, and turn the under body
mounted filter drain valve (located on thebottom of the filter assembly) counterclock
wise 1 full turn. Then turn the ignition switch
to the ON position, and allow any accumu-
lated water to drain. Leave the drain valve
open until all water and contaminants have
been removed. When clean fuel is visible,
close the drain valves by turning them fully
clockwise, and turn the ignition switch to
OFF.
If more than a couple ounces/milliliters of
fuel have been drained, follow the directions
for “Priming If The Engine Has Run Out Of
Fuel.”
Engine Mounted Fuel Filter
Replacement
NOTE:
• Using a fuel filter that does not meet the
manufacturer's filtration and water separat-
ing requirements can severely impact fuel
system life and reliability.
• The engine mounted filter housing is equipped with a No-Filter-No-Run (NFNR)
feature. Engine will not run if:
1. No filter is installed. 2. Inferior/Non-approved filter is used.
Use of OEM filter is required to ensure
vehicle will run.
CAUTION!
• Diesel fuel will damage blacktop pavingsurfaces. Drain the filter into an appro-
priate container.
• Do not prefill the fuel filter when install-
ing a new fuel filter. There is a possibility
debris could be introduced into the fuel
filter during this action. It is best to
install the filter dry and allow the in-tank
lift pump to prime the fuel system.
1. Ensure engine is turned off.
2. Place drain pan under the fuel filter drain hose.
3. Open the water drain valve 1/4 turn coun- terclockwise and completely drain fuel
