will disengage automatically after 25 seconds.
4. If you wish to stop the cranking of the engine prior to the engine starting, push the button again.
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 exten-
sion 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 in-
stalled 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.
Starting Fluids
The engine is equipped with a glow plug preheating
system. If the instructions in this manual are followed,
100 STARTING AND OPERATING

NORMAL OPERATION
Observe the following when the diesel engine is operat-
ing.
•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
module. Glow plug heater operation can run for several
minutes, once the heater operation is complete the volt-
meter needle will stabilize.
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.
Fuel Operating Range Chart
102 STARTING AND OPERATING

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.
Winter Front Usage
A winter front or cold weather cover is to be used in
ambient temperatures below 32°F (0°C), especially dur-
ing extended idle conditions to reduce condensation
build-up within engine crankcase. If a winter front or
cold weather cover is to be used, a percentage of the total
grille opening area must be left uncovered to provide
sufficient air flow to the charge air cooler and automatic
transmission oil cooler. The percentage of opening must
be increased with the increasing ambient air temperature
and/or engine load. If the cooling fan can be heard

cycling frequently, increase the size of the opening in the
winter front. 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 chambertemperatures can drop so low that the fuel may not burn
completely. 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.
104 STARTING AND OPERATING

Cooling System Tips — Automatic Transmission
To reduce the potential for engine and transmission
overheating 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.
