114STARTING AND OPERATING
COLD WEATHER PRECAUTIONS
Operation in ambient temperature below 32°F
(0°C) may require special considerations. The
following charts suggest these options:
Fuel Operating Range
NOTE:Use Ultra Low Sulfur Diesel (ULSD) Fuels ONLY.

Fuel Operating Range Chart

*Number 1 ULSD Fuel should only be used where
extended arctic conditions (0°F/-18°C) exist.
NOTE:
Use of Climatized ULSD or Number 1 ULSD Fuel
results in a noticeable decrease in fuel
economy.
Climatized ULSD Fuel is a blend of Number 2
ULSD and Number 1 ULSD Fuels which reduces
the temperature at which wax crystals form in
fuel.
The fuel grade should be clearly marked on the
pump at the fuel station.
The engine requires the use of ULSD Fuel. Use
of incorrect fuel could result in engine and
exhaust system damage Ú page 399.
If climatized or diesel Number 1 ULSD Fuel is
not available, and you are operating below
(20°F/-6°C), in sustained arctic conditions,
Mopar® Premium Diesel Fuel Treatment (or
equivalent) is recommended to avoid gelling
(see Fuel Operating Range Chart).

Under some circumstances increased engine
noise may be audible in the seconds following a
cold start. This is most likely to occur when using
fuel that isn't blended for the ambient tempera -
ture present. This may occur on an unseasonably
cold day or when a truck is fueled in a warmer
climate and driven to a colder climate. The noise
can typically be prevented by using Mopar®
Premium Diesel Fuel Treatment as recom -
mended (see Fuel Operating Range Chart).

Engine Oil Usage
For the correct engine oil viscosity Ú page 341.
Winter Front Cover Usage
A Winter front or cold weather cover is to be used
in ambient temperatures below 32°F (0°C),
especially during extended idle conditions. This
cover is equipped with four flaps for managing
total grille opening in varying ambient
temperatures. If a Winter front or cold weather
cover is to be used the flaps should be left in the
full open position to allow air flow to the charge air
cooler and automatic transmission oil cooler.
When ambient temperatures drop below 0°F
(-17°C) the four flaps need to be closed. A suitable
cold weather cover is available from a Mopar®
dealer.
Battery Blanket Usage
A battery loses 60% of its cranking power as the
battery temperature decreases to 0°F (-18°C). For
the same decrease in temperature, the engine
requires twice as much power to crank at the same
RPM. The use of 120 Volt AC powered battery
blankets will greatly increase starting capability at
low temperatures. Suitable battery blankets are
available from an authorized Mopar® dealer.

118STARTING AND OPERATING
Do Not Operate The Engine With Failed
Parts
All engine failures give some warning before the
parts fail. Be on the alert for changes in
performance, sounds, and visual evidence that the
engine requires service. Some important clues are:
Engine misfiring or vibrating severely.
Sudden loss of power.
Unusual engine noises.
Fuel, oil or coolant leaks.
Sudden change, outside the normal operating
range, in the engine operating temperature.
Excessive smoke.
Oil pressure drop.

ANUAL REGENERATION — IF EQUIPPED
On equipped Chassis Cabs, a manual regeneration
can be enable through the instrument cluster. The
manual regeneration will allow the DPF to
complete a regeneration, lowering the soot level
without having to drive the vehicle. The vehicle
must be in PARK to access this feature, and the
fuel level must be over 12.5% full. A message
displaying the time left on the regeneration will
appear on the instrument cluster, and the
instrument cluster will display the soot level
Ú page 81.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and
permits quicker starts in cold weather. Connect the
cord to a standard 110-115 Volt AC electrical
outlet with a grounded, three-wire extension cord.
The engine block heater cord is routed behind the
front bumper and accessible through the right hole
of the air dam.
The engine block heater must be plugged in at
least one hour to have an adequate warming effect
on the engine.
It includes a removable cap that is secured by a
tethered strap. It also has a c-clip that is used for
storage when not in use for the Winter months.
During Winter months, remove the heater cord
wiring assembly from itself on the c-clip.
NOTE:The block heater will require 110 Volt AC and
6.5 Amps to activate the heater element.
Block Heater Usage
For ambient temperatures below 0°F (-18°C),
engine block heater usage is recommended.
For ambient temperatures below –20°F (-29°C),
engine block heater usage is required.
ENGINE BREAK-IN RECOMMENDATIONS —
GASOLINE ENGINE
A long break-in period is not required for the engine
and drivetrain (transmission and axle) in your
vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles (100 km),
speeds up to 50 or 55 mph (80 or 90 km/h) are
desirable.
While cruising, brief full-throttle acceleration within
the limits of local traffic laws contributes to a good
break-in. Wide-open throttle acceleration in low
gear can be detrimental and should be avoided.
The engine oil installed in the engine at the factory
is a high-quality energy conserving type lubricant.
Oil changes should be consistent with anticipated
climate conditions under which vehicle operations
will occur. For the recommended viscosity and
quality grades Ú page 404.
NOTE:A new engine may consume some oil during its first
few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in
CAUTION!
Never use Non-Detergent Oil or Straight Mineral
Oil in the engine or damage may result.

System Unavailable.” The screen can be exited
out by pressing the “X” in the upper right hand
corner. This will return the display back to the
previously displayed screen.
Zoom View is not available with the AUX Camera
feature.
The display will always default to the Trailer
Camera display AUX 1.
ENGINE RUNAWAY
Diesel engine runaway is a rare condition affecting
diesel engines, where the engine consumes its
own lubrication oil and runs at higher and higher
RPM until it overspeeds to a point where it destroys
itself due to either mechanical failure or engine
seizure through lack of lubrication.
CAUTION!
To avoid vehicle damage, Trailer Surround
View should only be used as a parking aid. The
Trailer Surround View 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 Trailer Surround
View 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 Trailer Surround View.

WARNING!
In case of engine runaway due to flammable
fumes from fuel spills or turbocharger oil leaks
being sucked into the engine, do the following to
help avoid personal injury and/or vehicle
damage:
Turn the ignition switch to the OFF position.
Using a CO2 or dry chemical type fire extin
-
guisher, direct the spray from the fire extin -
guisher into the grille on the passenger side so

SERVICING AND MAINTENANCE333
NOTE:
Under no circumstances should oil change inter -
vals exceed 15,000 miles (24,000 km) or
12 months or 500 hours, whichever comes first.
It is recommended that every 3,000 miles
(4,800 km), check the engine oil level at least
30 minutes after a fully warmed engine is shut
off. Checking the oil level while the vehicle is on
level ground will improve the accuracy of the oil
level reading. Add oil only when the level is at or
below the ADD or MIN mark.
Severe service (high ambient temperature,
short trips, heavy loading, trailer towing,
off-road, or law enforcement use) may reduce
oil change intervals. If models configured with optional B20 capability
are operated with greater than 5% levels of
biodiesel, the oil change interval must not exceed
12,500 miles (20,000 km) or 400 hours,
whichever comes first under any circumstances.
See the Fuel Requirements section for more
information regarding operation with biodiesel
blend (B6-B20) fuel meeting ASTM specification
D-7467.
PERFORM SERVICE INDICATOR —

VEHICLE MAINTENANCE
An authorized dealer has the qualified service
personnel, special tools, and equipment to
perform all service operations in an expert
manner. Service Manuals are available which
include detailed service information for your
vehicle. Refer to these Service Manuals before
attempting any procedure yourself.
NOTE:Intentional tampering with emissions control
systems may void your warranty and could result in
civil penalties being assessed against you.
ENGINE OIL
Engine Oil Selection— Gasoline Engine
Use only the manufacturer's recommended fluid
Úpage 404.
NOTE:Hemi engines (6.4L) at times can tick right after
startup and then quiet down after approximately
30 seconds. This is normal and will not harm the
engine. This characteristic can be caused by short
drive cycles. For example, if the vehicle is started
then shut off after driving a short distance. Upon
restarting, you may experience a ticking sound.
Other causes could be if the vehicle is unused for
an extended period of time, incorrect oil, extended
oil changes or extended idling. If the engine
continues to tick or if the Malfunction Indicator
Light (MIL) comes on, see the nearest authorized
dealer.
Engine Oil Selection — Diesel Engine
Use only the manufacturer's recommended fluid
Úpage 404.
CAUTION!
It is essential when replacing the cables on
the battery that the positive cable is attached
to the positive post and the negative cable is
attached to the negative post. Battery posts
are marked positive (+) and negative (-) and
are identified on the battery case. Cable
clamps should be tight on the terminal posts
and free of corrosion.
If a “fast charger” is used while the battery is
in the vehicle, disconnect both vehicle battery
cables before connecting the charger to the
battery. Do not use a “fast charger” to provide
starting voltage.
CAUTION!
Precautions have been taken to safeguard all
parts and connections however, the pressures
generated by these machines is such that
complete protection against water ingress
cannot be guaranteed.
WARNING!
You can be badly injured working on or around a
