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.

WARNING!
•Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
• When leaving the vehicle, always make sure the
keyless ignition node is in the “OFF” mode, remove
the key fob from the vehicle and lock the vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a number
of reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the gear
selector.
• Do not leave the key fob in or near the vehicle, or in
a location accessible to children, and do not leave the
ignition of a vehicle equipped with Keyless Enter-
N-Go in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or move the
vehicle.
NORMAL OPERATION
Observe the following when the diesel engine is operating.
• All message center lights are off.
• Malfunction Indicator Light (MIL) is off.
• Engine Oil Pressure telltale is not illuminated.
• Voltmeter operation:
The voltmeter may show a gauge fluctuation at various
engine temperatures. This is caused by the glow plug
heating system. The number of cycles and the length of the
cycling operation is controlled by the engine control mod-
ule. Glow plug heater operation can run for several min-
utes, once the heater operation is complete the voltmeter
needle will stabilize.

NOTE: Under certain conditions the engine fan will run
after the engine is turned off. These conditions are under
high load and high temperature conditions.
Cooling System Tips — Automatic Transmission
To reduce the potential for engine and transmission over-
heating in high ambient temperature conditions, take the
following actions:
• City Driving — When stopped, shift the transmission
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.
NOTE: If the coolant temperature is too high the A/C will
automatically turn off.
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.

provide good performance. If the vehicle is exposed to
extreme cold (below 20°F or -7°C), or is required to operate
at colder-than-normal conditions for prolonged periods,
use climatized No. 2 diesel fuel or dilute the No. 2 diesel
fuel with 50% No. 1 diesel fuel. This will provide better
protection from fuel gelling or wax-plugging of the fuel
filter.
WARNING!
Do not use alcohol or gasoline as a fuel blending agent.
They can be unstable under certain conditions and
hazardous or explosive when mixed with diesel fuel.
Diesel fuel is seldom completely free of water. To prevent
fuel system trouble, drain the accumulated water from the
fuel/water separator using the fuel/water separator drain
provided on the fuel filter housing. If you buy good quality
fuel and follow the cold weather advice above, fuel condi-
tioners should not be required in your vehicle. If available
in your area, a high cetane “premium” diesel fuel may offer
improved cold-starting and warm-up performance.
CAUTION!
If the “Water in Fuel Indicator Light” remains on, DO
NOT START engine before you drain the water from
the fuel filter(s) to avoid engine damage. Refer to
“Maintenance Procedures/Draining Fuel/Water Sepa-
rator Filter” in “Maintaining Your Vehicle” for further
information.
Fuel Specifications
This diesel engine has been developed to take advantage of
the high energy content and generally lower cost No. 2
Ultra Low Sulfur diesel fuel or No. 2 Ultra Low Sulfur
climatized diesel fuels.
NOTE:
• If you accidentally fill the fuel tank with gasoline on
your diesel vehicle, do not start the engine. Damage to
the engine and fuel system could occur. Please call your
authorized dealer for service.
• A maximum blend of 5% biodiesel meeting ASTM
specification D-975 may be used with your diesel engine
without any adjustments to regular service schedules.
