WARNING!
•Do not start or run an engine in a closed garage or
confined area. Exhaust gas contains Carbon Monox-
ide (CO) which is odorless and colorless. Carbon
Monoxide is poisonous and can cause serious injury
or death when inhaled.
• Keep Remote Keyless Entry key fobs away from
children. Operation of the Remote Start System,
windows, door locks or other controls could cause
serious injury or death.
ENGINE BREAK-IN RECOMMENDATIONS
The diesel engine does not require a break-in period due to
its construction. Normal operation is allowed, providing
the following recommendations are followed:
• Warm up the engine before placing it under load.
• Do not operate the engine at idle for prolonged periods.
• Use the appropriate transmission gear to prevent engine
lugging. •
Observe vehicle oil pressure and temperature indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds 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 consistent with anticipated climate conditions
under which vehicle operations will occur. The recom-
mended viscosity and quality grades are shown under
“Fluids, Lubricants and Genuine Parts”, under “Maintain-
ing Your Vehicle” in this manual. NON-DETERGENT OR
STRAIGHT MINERAL OILS MUST NEVER BE USED.

4. Fuel Gauge •The pointer shows the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN position.
•
The fuel pump symbol points to the side of the
vehicle where the fuel filler door is located.
5. DEF Gauge •The DEF Gauge displays the actual level of Diesel
Exhaust Fluid in the DEF tank. Diesel Exhaust Fluid
(DEF) is required to maintain normal vehicle operation
and emissions compliance. If something is wrong with
the gauge, a DEF Warning Message or Malfunction
Indicator Light (MIL) will be displayed. More infor-
mation is available in the Instrument Cluster Display
section under the heading of Diesel Exhaust Fluid
(DEF) Warning Messages.

service if your vehicle overheats. If you decide to look
under the hood yourself, see “Maintaining Your Ve-
hicle.” Follow the warnings under the “Cooling Sys-
tem Pressure Cap” paragraph.
CAUTION!
Driving with a hot engine cooling system could dam-
age your vehicle. If the temperature gauge reads “H”
pull over and stop the vehicle. Idle the vehicle with the
air conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on the
“H”, turn the engine off immediately and call an
authorized dealer for service.
NOTE:
• The 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.

5. Check that the oil pressure warning light has turned off.
6. Release the parking brake.
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 temperatures under -20°F (-28°C).
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 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.
Starting Fluids
The engine is equipped with a glow plug preheating
system. If the instructions in this manual are followed, the
engine should start in all conditions and no type of starting
fluid should be used.
34 STARTING AND OPERATING

below 0°F (-17°C) the four flaps need to be closed. A
suitable cold weather cover is available from your MOPAR
dealer.
Engine Warm-Up
Avoid full throttle operation when the engine is cold. When
starting a cold engine, bring the engine up to operating
speed slowly to allow the oil pressure to stabilize as the
engine warms up.
If temperatures are below 32°F (0°C), operate the engine at
moderate speeds for five minutes before full loads are
applied.
Engine Idling
Avoid prolonged idling, long periods of idling may be
harmful to your engine because combustion chamber tem-
peratures can drop so low that the fuel may not burncompletely. Incomplete combustion allows carbon and
varnish to form on piston rings, cylinder head valves, and
injector nozzles. Also, the unburned fuel can enter the
crankcase, diluting the oil and causing rapid wear to the
engine.
Stopping The Engine
After full load operation, idle the engine for a few minutes
before shutting it down. This idle period will allow the
lubricating oil and coolant to carry excess heat away from
the turbocharger.
NOTE:
Refer to the following chart for proper engine
shutdown.

38 STARTING 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.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms engine coolant and permits
quicker starts in cold weather. Connect the heater cord to a
ground-fault interrupter protected 110–115 Volt AC electri-
cal 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 for long periods of time and should be plugged in two hours prior to start. Its use is required for
cold starts with temperatures under -20°F (-28°C).
To ensure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your authorized dealer) is recommended.
WARNING!
Remember to disconnect the cord before driving. Dam-
age to the 110–115 Volt electrical cord could cause
electrocution.
NOTE: The block heater will require 110 Volts AC and
6.5 Amps to activate the heater element.
FUEL REQUIREMENTS
Use good quality diesel fuel from a reputable supplier in
your vehicle. Federal law requires that you must fuel this
vehicle with Ultra Low Sulfur Highway Diesel fuel
(15 ppm Sulfur maximum) and prohibits the use of Low
Sulfur Highway Diesel fuel (500 ppm Sulfur maximum) to
avoid damage to the emissions control system.
For most year-round service, No. 2 diesel fuel meeting
ASTM (formerly known as the American Society for Test-
ing and Materials) specification D-975 Grade S15 will
40 STARTING AND OPERATING

Bulk Fuel Storage — Diesel Fuel
If you store quantities of fuel, good maintenance 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 system 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 “Maintenance
Procedures/Priming If The Engine Has Run Out Of Fuel”
in “Maintaining Your Vehicle” for further information.
WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.
Diesel Exhaust Fluid Storage
Diesel Exhaust Fluid (DEF) is considered a very stable
product with a long shelf life. If DEF is kept in tempera-
tures 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 temperatures. 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 contact 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.
