2. Press and hold the brake pedal while pushing theENGINE START/STOP button once.
NOTE: A delay of the start of up to five seconds is possible
under very cold conditions. The Wait to Starttelltale will
be illuminated during the pre-heat process, When the
engine Wait To Start light goes off the engine will auto-
matically crank.
CAUTION!
If the “Water in Fuel Indicator Light” remains on, DO
NOT START the engine before you drain the water
from the fuel filters to avoid engine damage. Refer to
“Maintenance Procedures/Draining Fuel/Water Sepa-
rator Filter” in “Maintaining Your Vehicle” for further
information.
3. The system will automatically engage the starter to crank the engine. If the vehicle fails to start, the starter
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 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
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

5. After engine start-up, check to see that there is oilpressure.
6. Allow the engine to idle about three minutes until the manifold heaters have completed the post-heat cycle.
7. Release the parking brake and drive.
NOTE:
• Engine idle speed will automatically increase to 1,000
RPM and engage the Variable Geometry Turbocharger at
low coolant temperatures to improve engine warm-up.
• The engine may not automatically crank after the engine
Wait To Start telltale goes off if a door or the hood is
ajar.
• If the engine stalls, or if the ignition switch is left ON for
more than two minutes after the “Wait To Start Light”
goes out, reset the grid heaters by turning the ignition
switch to the OFF position for at least five seconds and
then back ON. Repeat steps 1 through 7 of “Keyless

Temperature Below 66° F (19° C).”Extreme Cold Weather
The Cummins diesel engine is equipped with several
features designed to assist cold weather starting and op-
eration:
• The engine block heater is a resistance heater installed in
the water jacket of the engine just above and behind the
oil filter. It requires a 110–115 Volt AC electrical outlet
with a grounded, three-wire extension cord.
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 housings aid in
preventing fuel gelling. It is controlled by a built-in
thermostat.
• A heated intake air system both improves engine start-
ing and reduces the amount of white smoke generated
by a warming engine.

STARTING AND OPERATING 125
Do Not Operate The Engine With Low Oil Pressure
When the engine is at normal operating temperature, the
minimum oil pressures required are:
Idle 700 to 800 RPM 10 psi (69 kPa)
Full speed and load 30 psi (207 kPa)
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.
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.
The engine block heater cord is routed under the hood to
the right side and can be located just behind the grille near
the headlamp.
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.
The block heater must be plugged in at least one hour to
have an adequate warming effect on the coolant.5
STARTING AND OPERATING 137
WARNING!
Remember to disconnect the cord before driving.
Damage 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.
Block Heater Usage
For ambient temperatures below 0°F (-18°C), engine block
heater usage is recommended.
For ambient temperatures below –20°F (-29°C), engine
block heater usage is required.
DIESEL EXHAUST BRAKE (ENGINE BRAKING)
The purpose of the exhaust brake (engine braking) feature
is to supply negative (braking) torque from the engine.
Typically, the engine braking is used for, but not limited to,
vehicle towing applications where vehicle braking can be
achieved by the internal engine power, thereby sparing the
mechanical brakes of the vehicle.
Benefits of the exhaust brake are:
• Vehicle driving control. •
Reduced brake fade.
• Longer brake life.
• Faster cab warm-up.
The exhaust brake feature will only function when the
driver toggles it on by pushing the exhaust brake button
until the Exhaust Brake Indicator is illuminated. Normal
(Full Strength) exhaust brake mode is indicated by a yellow
Exhaust Brake Indicator.
Once the Exhaust Brake Indicator” is illuminated and the
vehicle is moving faster than 5 mph (8 km/h); the exhaust
brake will automatically operate when the driver removes
