gine does not start, contact your authorized
dealer.
Extreme Cold Weather
Your vehicle may be equipped with three
heating elements; one engine block heater (a
resistance heater installed in the water jacket
of the engine) and two transmission heaters
(one resistance heater installed under the oil
reservoir of the hydraulic actuation system
and one on the differential cover of the trans-
mission). To ensure reliable starting/
operating in extreme cold temperatures, use
of an externally powered electric engine
block/transmission heater (available from
your authorized dealer) is recommended.
They require a 110–115 Volt AC electrical
outlet with a grounded, three-wire extension
cord. Their use is recommended for environ-
ments that routinely fall below -10°F
(-23°C). They should be used when the ve-
hicle has not been running overnight or lon-
ger periods and should be plugged in two
hours prior to start. Their use is required for
cold starts with temperatures under -17°F
(-27°C).NOTE:
The engine is designed to work at an ambient
temperature ranging from -22°F to + 122°F
(-30°C to + 50C°). Rubber, pipes, timing belt
cover and electronic devices are not designed
to work out of this range.
In the case of LOW temperature after Start-
ing, the Automated Manual Transmission
may not be able to engage first gear. In this
case a message "Shift not allowed" appears.
In this situation use the engine block heater.
NOTE:
The engine and transmission block heater
cord is a factory installed option. If your
vehicle is not equipped, heater cords are
available from your authorized Mopar dealer.
• A 12 Volt heater built into the fuel filter
housing aids in preventing fuel gelling. It is
controlled by a built-in thermostat.
• A Diesel Pre-Heat system both improves engine starting and reduces the amount of
white smoke generated by a warming
engine.
NORMAL OPERATION
Observe the following when the diesel engine
is operating.
• All message center lights are off.
• Malfunction Indicator Light (MIL) is off.
• Generic Warning Light is off.
• Engine Oil Pressure telltale is notilluminated.
Stopping The Diesel Engine
Idle the engine a few minutes before routine
shutdown. After full load operation, idle the
engine three to five minutes before shutting it
down. This idle period will allow the lubricat-
ing oil and coolant to carry excess heat away
from the combustion chamber, bearings, in-
ternal components, and turbocharger. This is
especially important for turbocharged diesel
engines.
NOTE:
Refer to the following chart for proper engine
shutdown.STARTING AND OPERATING

• Vary accelerator pedal position at highwayspeeds when carrying or towing significant
weight.
NOTE:
Light duty operation such as light trailer
towing or no load operation will extend the
time before the engine is at full efficiency.
Reduced fuel economy and power may be
seen at this time.
The engine oil installed in the engine at the
factory is a high-quality energy conserving
type lubricant. Oil changes should be consis-
tent with anticipated climate conditions un-
der which vehicle operations will occur. The
recommended viscosity and quality grades
are shown under “Fluids And Lubricants” in
the “Technical Specifications” chapter in
this manual. NON-DETERGENT OR
STRAIGHT MINERAL OILS MUST NEVER
BE USED.ELECTRIC PARK BRAKE (EPB) —
DIESEL ONLY (IF EQUIPPED)
Your vehicle is equipped with an Electric
Park Brake System (EPB) that offers simple
operation, and some additional features that
make the park brake more convenient and
useful.
The park brake is primarily intended to pre-
vent the vehicle from rolling while parked.
Before leaving the vehicle, make sure that
the park brake is applied.
You can engage the park brake in two ways;
• Manually, by applying the park brake switch.
• Automatically, by the Auto Park Brake fea- ture whenever the vehicle speed is below
1.25 mph (2 km/h) and the ignition switch
is in the STOP/OFF position.
The park brake switch is located on the in-
strument panel to the right of the instrument
cluster. To apply the parking brake manually, pull and
tilt the top of the switch away from the
instrument panel momentarily. You may hear
a mechanical sound while the parking brake
operates; this is normal operating noise.
Once the parking brake is fully engaged, the
BRAKE warning lamp in the instrument clus-
ter and an indicator on the switch will illumi-
nate. The park brake can be applied even

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) up to
the maximum speed of 100 mph (160 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the
RES button, or normal brake pressure while
slowing the vehicle will deactivate Speed
Control without erasing the set speed
memory. Rotating the center ring upward to
turn the system off or turning the ignition
switch OFF erases the set speed memory.
PARKSENSE REAR PARK ASSIST
If an obstacle is behind the vehicle when
REVERSE gear is engaged, an audible alert is
activated.The tones emitted by the loudspeaker inform
the driver that the vehicle is approaching an
obstacle. The pauses between the tones are
directly proportional to the distance from the
obstacle. Pulses emitted in quick succession
indicate the presence of a very close ob-
stacle. A continuous tone indicates that the
obstacle is less than 12 inches (30 cm) away.
PARKVIEW REAR BACK-UP CAMERA
You can see an on-screen image of the rear of
your vehicle whenever the gear selector is put
into REVERSE. The ParkView Rear Back-Up
Camera image is displayed on the touch-
screen display located on the center stack of
the instrument panel.
NOTE:
If the touchscreen display appears foggy,
clean the camera lens located on the top rear
of the vehicle below the center light.
WARNING!
Drivers must be careful when backing up
even when using the Rear Back-Up Cam-
era. Always check carefully behind your

vehicle, and be sure to check for pedestri-
ans, animals, other vehicles, obstructions,
or blind spots before backing up. You are
responsible for the safety of your surround-
ings and must continue to pay attention
while backing up. Failure to do so can
result in serious injury or death.
REFUELING THE VEHICLE — GAS

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.
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
Fuel/DEF Fill Locations

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 under the vehicle.
Adding Diesel Exhaust Fluid
NOTE:
Driving conditions (altitude, vehicle speed,
load, etc.) will effect the amount of DEF that
is used by your vehicle.
DEF Fill Procedure
NOTE:
Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for the correct fluid type.
CAUTION!
It is extremely important to avoid any con-
tamination of the diesel fuel with Diesel
Exhaust Fluid (DEF). Ensure that the die-
sel fuel filler cap is in place and com-
pletely tightened before opening or filling
the DEF.
1. Remove cap from DEF filler neck (located on drivers side of the vehicle in the fuel
door).
2. Insert DEF fill adapter/nozzle into DEF tank filler neck.
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.

CAUTION!
• When DEF is spilled, clean the areaimmediately 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.
• Never add anything other than DEF to the 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.
• DEF pump nozzle automatically shuts off.
4. Reinstall cap onto DEF filler neck.
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.
