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.

23. Generic Warning LightThe Generic Warning Light will illuminate in
blinking mode if any of the following condi-
tions occur:
• Air Bag Warning Light Fault
• Engine Oil Pressure Sensor Failure
• Parking Sensor Failure
• Water In Fuel Presence
• Fuel Cutoff Intervention
• “Engine Minimum Oil Level”
• “Engine Min Oil Sensor Fail”
• Swivel Seat Malfunction
If the Generic Warning Light is blinking an air bag system
failure may be present, see an authorized dealer as soon
as possible. 24. Air Bag Warning Light
This light will turn on for four to eight seconds
as a bulb check when the ignition switch is first
turned to ON/RUN. If the light is either not on
during starting, stays on, or turns on while
driving, have the system inspected at an authorized
dealer as soon as possible. Refer to “Occupant Restraints”
in “Things To Know Before Starting Your Vehicle” for
further information.
25. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the

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.
