ENGINE BREAK-IN RECOMMENDATIONS
The diesel engine does not require a break-in period due
to its construction. Normal operation is allowed, provid-
ing 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 indica-
tors.
• Check the coolant and oil levels frequently.
• Vary accelerator pedal 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 recommended viscosity and quality grades are
shown under “Fluids, Lubricants and Genuine Parts”,
under “Maintaining Your Vehicle” in this manual. NON-
DETERGENT OR STRAIGHT MINERAL OILS MUST
NEVER BE USED.
8 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

12. Oil Pressure Warning LightThis light indicates low engine oil pressure. The
light should turn on momentarily when the engine is
started. If the light turns on while driving, stop the
vehicle and shut off the engine as soon as possible. A
chime will sound when this light turns on.
Do not operate the vehicle until the cause is corrected.
This light does not indicate how much oil is in the engine.
The engine oil level must be checked under the hood.
13. Electronic Speed Control Set Indicator Light
This light will turn on when the electronic
speed control is set.
14. Charging System Light — If Equipped This light shows the status of the electrical charg-
ing system. The light should come on when the
ignition switch is first turned to ON/RUN and remain on briefly as a bulb check. If the Charging System light
remains on, or comes on while driving, it means that the
vehicle is experiencing a problem with the charging
system. Obtain SERVICE IMMEDIATELY. See your au-
thorized dealer.
Refer to “Jump Starting Procedures” in “What To Do In
Emergencies” if jump starting is required.
15. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
indicate that the parking brake is applied or
that the brake fluid level is low.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction. In this case, the light will
remain on until the condition has been corrected. If the

CAUTION!
Driving with a hot engine cooling system could
damage 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” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealer for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your
(Continued)
WARNING!(Continued)
Vehicle.” Follow the warnings under the “Cooling
System Pressure Cap” paragraph.
18. Engine Temperature Warning Light
This light warns of an overheated engine condition. As
engine coolant temperatures rise and the gauge ap-
proaches H, this indicator will illuminate and a single
chime will sound after reaching a set threshold.
If the light turns on while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also,
shift the transmission into NEUTRAL with the park
brake applied and idle the vehicle. If the temperature
reading does not return to normal, turn the engine off
immediately and call for service. Refer to “If Your Engine
Overheats” in “What To Do In Emergencies” for further
information.

6. Check that the oil pressure warning light has turnedoff.
7. Release the parking brake.
To start the engine if the transmission is faulty, the
“Delayed startup” procedure may be required.
NOTE: Not all Transmission Failures requires the “De-
layed startup” Procedure, it depends on the type of
failure.
(refer to Instrument Cluster Messages underAuto-
mated Manual Transmission in this section for further
information):
• Begin with the key in the OFF position.
• Press and hold the brake pedal. •
Turn the key to the START/AVV position and hold it
there for at least seven seconds with the brake de-
pressed. The engine will start, and the transmission
will operate in recovery mode (maximum gear permit-
ted = 3rd, automatic mode not available). If the engine
does not start, contact your authorized dealer.
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.
WARNING!
• Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.

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 start-
ing and reduces the amount of white smoke generated
by a warming engine.
NORMAL OPERATION
Observe the following when the diesel engine is operat-
ing.
• All message center lights are off.
• Malfunction Indicator Light (MIL) is off.
• Generic Warning Light is off. •
Engine Oil Pressure telltale is not illuminated.
Cold Weather Precautions
Operation in ambient temperature below 32°F (0°C) may
require special considerations. The following charts sug-
gest these options:
Fuel Operating Range
NOTE: Use “Ultra Low Sulfur Diesel Fuels” ONLY.

*No. 1 Ultra Low Sulfur Diesel Fuel should only be used
where extended arctic conditions (-10°F/-23°C) exist.
NOTE:
•Use of Climatized Ultra Low Sulfur Diesel Fuel or
Number 1 Ultra Low Sulfur Diesel Fuel results in a
noticeable decrease in fuel economy.
• Climatized Ultra Low Sulfur Diesel Fuel is a blend of
Number 2 Ultra Low Sulfur and Number 1 Ultra Low
Sulfur Diesel 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 “Ultra Low Sulfur
Diesel Fuel”. Use of incorrect fuel could result in
engine and exhaust system damage. Refer to “Fuel
Requirements” in “Starting And Operating” for fur-
ther information. •
Commercially available fuel additives are not neces-
sary for the proper operation of your diesel engine.
However, if seasonably adjusted fuel is not available
and you are operating below 20°F (-6°C), MOPAR
Premium Diesel Fuel Treatment (or equivalent) may be
beneficial to avoid fuel gelling.
Engine Oil Usage
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for the correct engine oil viscosity.
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.

Cooling System Tips — Automated Manual
Transmission
To reduce potential for engine and transmission over-
heating in high ambient temperature conditions, take the
following actions:
•City Driving
— When stopped, shift the transmis-
sion into NEUTRAL and increase engine idle
speed.
• Highway Driving— Reduce your speed.
•Up Steep Hills— Select a lower transmission gear.
•Air Conditioning— Turn it off temporarily. Do Not Operate The Engine With Low Oil
Pressure
If the low oil pressure warning light turns on while
driving, stop the vehicle and shut down the engine as
soon as possible. A chime will sound when the light turns
on.
NOTE:
Do not operate the vehicle until the cause is
corrected. This light does not show how much oil is in the
engine. The engine oil level must be checked under the
hood.
CAUTION!
If oil pressure falls to less than normal readings, shut
the engine off immediately. Failure to do so could
result in immediate and severe engine damage.
44 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/TRANSMISSION HEATER — IF
EQUIPPED
To ensure reliable starting/operating at these tempera-
tures, use of an externally powered electric engine block/
transmission heater (available from your authorized
dealer) is recommended.
The engine block heater warms engine coolant and
permits quicker starts in cold weather. The transmission
heaters warm gearbox oil and hydraulic actuation system
oil to operate in cold weather. Connect the heater cord to
a ground-fault interrupter protected 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

only when the level on the dipstick is below the mini-
mum notch. The total capacity from the minimum notch
to the maximum notch is 1.7 quarts (1.6 liters).
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could damage
your engine.
NOTE: It is possible for your oil level to be slightly
higher than a previous check. This would be due to diesel
fuel that may temporarily be in the crankcase due to
operation of the diesel particulate filter regeneration
strategy. This fuel will evaporate out under normal
operation.
Never operate the engine with oil level below the mini-
mum notch or above the upper maximum notch.
Change Engine Oil
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Engine Oil Viscosity (SAE Grade)
CAUTION!
Your vehicle is equipped with an advanced technol-
ogy Diesel Engine and an emission device designed
to limit Diesel Particulate Emissions from being
released into the atmosphere. The durability of your
engine and life expectancy of this diesel particulate
filter emission device is highly dependent on the use
of the correct engine oil.
Only use ACEA C3 SAE 5W-30 Synthetic Low Ash engine
oil meeting FCA US Material Standard MS-11106 or
Pennzoil Ultra Euro L full synthetic 5W-30 motor oil,
