other controls, or move the vehicle.
• Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury
or death.
NOTE:
Engine start up in very low ambient tempera-
ture could result in evident white smoke. This
condition will disappear as the engine warms
up.
CAUTION!
• The engine is allowed to crank as long as 30 seconds. If the engine fails to start
during this period, please wait at least
two minutes for the starter to cool before
repeating start procedure.
• If the “Water in Fuel Indicator Light”
remains on, DO NOT START engine be-
fore you drain the water from the fuel
filters to avoid engine damage. Refer to
“Draining Fuel/Water Separator Filter”

ther information.
Automatic Transmission
Start the engine with the transmission gear
selector in the PARK position. Apply the
brake before shifting to any driving range.
Extreme Cold Weather
The engine block heater is a resistance heater
installed in the water jacket of the engine. It
requires a 110–115 Volt AC electrical outlet
with a grounded, three-wire extension cord.
Its use is recommended for environments
that routinely fall below -10°F (-23°C). It
should be used when the vehicle has not been
running overnight or longer periods and
should be plugged in two hours prior to start.
Its use is required for cold starts with tem-
peratures under -20°F (-28°C).
151

NOTE:
The engine 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 filterhousing 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 Starting Procedure — Keyless
Enter-N-Go
Observe the instrument panel cluster lights
when starting the engine.
NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or press-
ing the accelerator pedal

STARTING AND OPERATING
152

WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
power transfer unit in the NEUTRAL (N)
position without first fully engaging the
parking brake. The NEUTRAL (N) position
disengages both the front and rear drive-
shafts from the powertrain and will allow
the vehicle to roll, even if the transmission
is in PARK. The parking brake should al-
ways be applied when the driver is not in
the vehicle.
4WD LOW
This range is for low speed four-wheel drive. It
provides an additional gear reduction which
allows for increased torque to be delivered to
both the front and rear wheels while providing
maximum pulling power for loose, slippery
road surfaces only. Do not exceed 25 mph
(40 km/h).
NOTE:
Refer to “Selec-Terrain – If Equipped” for
further information on the various positions
and their intended usages.
Shifting Procedures
4WD HI To 4WD LOW
With the vehicle at speeds of 0 to 3 mph (0 to
5 km/h), the ignition switch in the ON posi-
tion or the engine running, shift the transmis-
sion into “N”, and push the “4WD LOW”
button once on the transfer case switch. The
“4WD LOW” indicator light in the instrument
cluster will begin to flash and remain on solid
when the shift is complete.NOTE:
If shift conditions/interlocks are not met, or a
transfer case motor temperature protection
condition exists, a “For 4x4 Low Slow Below
3 mph (5 km/h) Put Trans in “N” Press
4 Low” message will flash from the instru-
ment cluster display. Refer to “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
4WD LOW To 4WD HI

NOTE:
• If shift conditions/interlocks are not met,or a transfer case motor temperature pro-
tection condition exists, a “For 4x4 High
Slow Below 3 mph (5 km/h) Put Trans in N
push 4 Low” message will flash from the
instrument cluster display. Refer to “In-
strument Cluster Display” in “Getting To
Know Your Instrument Panel” for further
information.
• Shifting into or out of 4WD LOW is pos- sible with the vehicle completely stopped;
however, difficulty may occur due to the
mating clutch teeth not being properly
aligned. Several attempts may be required
for clutch teeth alignment and shift
completion to occur. The preferred
method is with the vehicle rolling 0 to
3 mph (0 to 5 km/h). If the vehicle is
moving faster than 3 mph (5 km/h), the
transfer case will not allow the shift.Shifting Into NEUTRAL (N)
WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
transfer case in the NEUTRAL (N) position
without first fully engaging the parking
brake. The NEUTRAL (N) position disen-
gages both the front and rear drive shafts
from the powertrain and will allow the
vehicle to roll, even if the transmission is
in PARK. The parking brake should always
be applied when the driver is not in the
vehicle.
1. Bring the vehicle to a complete stop, with the engine running.
2. Press and hold the brake pedal.
3. Shift the transmission into NEUTRAL.
4. If vehicle is equipped with Quadra-Lift air suspension, ensure the vehicle is set to
Normal Ride Height.
5. Using a ballpoint pen or similar object, push and hold the recessed transfer case
NEUTRAL (N) button (located by the se-
lector switch) for four seconds. The light behind the NEUTRAL (N) symbol will
blink, indicating shift in progress. The
light will stop blinking (stay on solid)
when the shift to NEUTRAL (N) is com-
plete. A “NEUTRAL” message will appear
in the instrument cluster display. Refer to
“Instrument Cluster Display” in “Getting
To Know Your Instrument Panel” for fur-
ther information.
6. After the shift is completed and the NEU- TRAL (N) light stays on, release the NEU-
TRAL (N) button.
7. Shift the transmission into REVERSE.

79 inches (200 cm) from the rear fascia/
bumper in the horizontal direction, depend-
ing on the location, type and orientation of
the obstacle.
The six ParkSense sensors, located in the
front fascia/bumper, monitor the area in front
of the vehicle that is within the sensors’ field
of view. The sensors can detect obstacles
from approximately 12 inches (30 cm) up to
47 inches (120 cm) from the front fascia/
bumper in the horizontal direction, depend-
ing on the location, type and orientation of
the obstacle.
When an object is detected within 79 inches
(200 cm) behind the rear bumper while the
vehicle is in REVERSE, a warning will appear
in the instrument cluster display. In addition
a chime will sound (when Sound and Display
is selected from the Customer Programmable
Features section of the Uconnect System
screen). As the vehicle moves closer to the
object, the chime rate will change from single
1/2 second tone (for rear only), to slow (for
rear only), to fast, to continuous.Activation/Deactivation
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. If
your vehicle is equipped with an Automatic
Transmission, the vehicle brakes may be au-
tomatically applied and released when per-
forming a reverse parking maneuver if the
system detects a possible collision with an
obstacle.
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
display warning will appear in the instrument
cluster display 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).
Engagement/Disengagement
To disengage the system, push the ParkSense
switch, located on the switch panel below the
Uconnect display.
When the system passes from engaged to
disengaged and vice versa, it is always ac-
companied by a dedicated message in the
instrument cluster display.
System engaged:ParkSense switch LED off.
System disengaged: ParkSense switch LED on
constantly.
The ParkSense switch LED lights up also in
the case of a ParkSense system failure. If the
button is pushed with a system failure, the
ParkSense switch LED flashes for about
5 seconds, then it stays on constantly.
After the ParkSense has been disengaged, it
will stay in this condition until the following
engagement, even if the ignition device
passes from ON/RUN to OFF and then again
to ON/RUN.

Avoid Using Contaminated Fuel
Fuel that is contaminated by water or dirt can
cause severe damage to the engine fuel sys-
tem. Proper maintenance of the engine fuel filter and fuel tank is essential. Refer to
“Dealer Service” in “Servicing And Mainte-
nance” for further information.
Bulk Fuel Storage — Diesel Fuel
If you store quantities of fuel, good mainte-
nance 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 sys-
tem 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, refer to “Dealer
Service / Priming If The Engine Has Run Out
Of Fuel” in “Servicing And Maintenance” for
further information.
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.
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.
