Extreme Cold Weather
The Cummins® diesel engine is equipped with several
features designed to assist cold weather starting and
operation:
•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
starting and reduces the amount of white smoke
generated by a warming engine.

210 STARTING AND OPERATING

•Automatic equipped vehicles with optional Keyless
Enter-N-Go™ – If the start button is pushed once
while in park with the ignition off and driver ’s foot on
the brake pedal, the vehicle will automatically crank
and start after the Wait to Start time has elapsed. If it is
desired to abort the start process before it completes,
the driver ’s foot should be fully removed from the
brake pedal prior to pushing the start button again in
order for the ignition to move directly to off.
•If the engine stalls, or if the ignition switch is left ON
for more than two minutes after the “Wait To Start”
telltale 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 5 of
“Starting Procedure – Engine Manifold Air Tempera-
ture Below 66°F (19°C).”Starting Procedure — Engine Manifold Air
Temperature Below 0°F (-18°C)
In extremely cold weather below 0°F (-18°C) it may be
beneficial to cycle the manifold heaters twice before
attempting to start the engine. This can be accomplished
by turning the ignition OFF for at least five seconds and
then back ON after the “Wait To Start” telltale has turned
off, but before the engine is started. However, excessive
cycling of the manifold heaters will result in damage to
the heater elements or reduced battery voltage.
NOTE:If multiple pre-heat cycles are used before start-
ing, additional engine run time may be required to
maintain battery state of charge at a satisfactory level.
1. If the engine stalls after the initial start, the ignition
must be turned to the OFF position for at least five
seconds and then to the ON position to recycle the
manifold heaters.

Starting Fluids
WARNING!
Starting fluids or flammable liquids must never be
used in the Cummins® diesel engine (see Warning
label). Never pour diesel fuel, flammable liquid, start-
ing fluids (ether) into the air cleaner canister, air intake
piping, or turbocharger inlet in an attempt to start the
vehicle. This could result in a flash fire and explosion
causing serious personal injury and engine damage.
The engine is equipped with an automatic electric air
preheating system. If the instructions in this manual are
followed, the engine should start in all conditions.
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
ignition is in the OFF position, 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 transmission gear selector. Do not leave the
key fob in or near the vehicle (or in a location

STARTING AND OPERATING 213

Your vehicle is equipped with a turbo speed limiter, this
feature limits the engine speed to 1,200 RPM when
engine coolant temperatures are below 70°F (21°C). This
feature is designed to protect the turbocharger from
damage and will only operate in PARK or NEUTRAL.
If temperatures are below 32°F (0°C), operate the engine
at moderate speeds for five minutes before full loads are
applied.
NOTE:If ambient temperatures are low and the coolant
temperature is below 180°F (82°C), the engine idle speed
will slowly increase to 1,000 RPM after two minutes of
idle, if the following conditions are met:
•Foot is off brake pedal and throttle pedal.
•Automatic transmission is in PARK.
•Vehicle speed is 0 mph (0 km/h).
•Applying the throttle will cancel fast idle.•Operating the exhaust brake at idle will greatly im-
prove warm up rate and will help keep the engine
close to operating temperature during extended idle.
Engine Idling
Avoid prolonged idling, long periods of idling may be
harmful to your engine because combustion chamber
temperatures can drop so low that the fuel may not burn
completely. Incomplete combustion allows carbon and
varnish to form on piston rings, engine valves, and
injector nozzles. Also, the unburned fuel can enter the
crankcase, diluting the oil and causing rapid wear to the
engine.
If the engine is allowed to idle, under some conditions
the idle speed may increase to 900 RPM then return to
normal idle speed. This is normal operation.

NOTE:For EVIC messages related to the vehicle’s ex-
haust system, refer to “Maintenance Procedures/
Intervention Regeneration Strategy – EVIC Message Pro-
cess Flow” in “Maintaining Your Vehicle” for further
information.
Idle-Up Feature — Automatic Transmission Only
The driver-controlled high idle speed feature will help
increase cylinder temperatures and provide additional
cab heat, however, excessive idling may still cause the
exhaust aftertreatment system to not properly regenerate.
Extended periods of idle time should be avoided.
The Idle-Up feature uses the speed control switches to
increase engine idle speed and quickly warm the vehi-
cle’s interior.1. With the transmission in PARK, the parking brake
applied, and the engine running, press the speed
control switch to the ON position, then press the SET
switch.
2. The engine RPM will go up to 1100 RPM. To increase
the RPM, press and hold the ACCEL/RESUME switch
and the idle speed will increase to approximately 1500
RPM. To decrease the RPM, press and hold the DECEL
switch and the idle speed will decrease to approxi-
mately 1100 RPM.
3. To cancel the Idle–Up feature, either press the CAN-
CEL switch, press the ON/OFF switch, or press the
brake pedal.
Stopping The Engine
Idle the engine a few minutes before routine shutdown.
After full load operation, idle the engine three to five
minutes before shutting it down. This idle period will
