ENGINE RUNAWAY
WARNING!In case of engine runaway due to flammable fumes
from gasoline spills or turbocharger oil leaks being
sucked into the engine do the following to help
avoid personal injury and/or vehicle damage:
1. Shut off engine ignition switch.
2. Using a CO 2
or dry chemical type fire extin-
guisher, direct the spray from the fire extinguisher
into the grille on the passenger side so that the spray
enters the engine air intake.
The inlet for the engine air intake is located behind the
passenger side headlamp and receives air through the
grille FUEL REQUIREMENTS
Fuel Requirements (Gas Engines)
The 5.7L engine is designed to meet all
emissions regulations and provide satisfac-
tory fuel economy and performance when
using high quality unleaded gasoline hav-
ing an octane range of 87 to 89. The manu-
facturer recommends the use of 89 octane
for optimum performance. The routine use of premium
gasoline is not recommended. The use of premium
gasoline will provide no benefit over high quality regular
and mid-grade gasolines, and in some circumstances
may result in poorer performance.
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required. STARTING AND OPERATING 327

• The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
damage the emission control system.
• An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your dealer for service assistance.
• When pulling a heavy load or driving a fully loaded
vehicle when the humidity is low and the temperature
is high, use a premium unleaded fuel to help prevent
spark knock. If spark knock persists, lighten the load,
or engine piston damage may result.
• The use of fuel additives which are now being sold as
octane enhancers is not recommended. Many of these
products contain high concentrations of methanol. Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives is not
the responsibility of the manufacturer.
NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
Carbon Monoxide Warnings
WARNING!Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
• Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas which can kill.
Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the330 STARTING AND OPERATING

Recreational Towing Procedure — Manual Shift
Transfer Case — If Equipped
Use the following procedure to prepare your vehicle for
recreational towing:

16. Release parking brake.
NOTE: Items 1 through 5 are requirements that must be
met prior to depressing the Neutral (N) selection button,
and must continue to be met until the 4 seconds elapses
and the shift has been completed. If any of these require-
ments (with the exception of 3 - Key ON) are not met
prior to depressing the Neutral (N) button or are no
longer met during the 4 second timer, then the Neutral
(N) indicator light will flash continuously until all re-
quirements are met or until the Neutral (N) button is
released.
NOTE: The ignition key must be ON for a shift to take
place and for the position indicator lights to be operable.
If the key in not ON, the shift will not take place and no
position indicator lights will be on or flashing.364 STARTING AND OPERATING

NOTE: Flashing neutral (N) position indicator light
indicates that shift requirements have not been met.
CAUTION!Damage to the transmission may occur if the trans-
mission is shifted into Park (P) with the transfer case
in Neutral (N) and the engine RUNNING. With the
transfer case in Neutral (N) ensure that the engine is
OFF prior to shifting the transmission into Park (P).

NOTE: Items 1 through 5 are requirements that must be
met prior to depressing the Neutral (N) selection button,
and must continue to be met until 1 second elapses and
the shift has been completed. If any of these requirements
(with the exception of 3 - key ON) are not met prior to
depressing the Neutral (N) button or are no longer met
during the 1 second time, then all of the mode position
indicator lights will flash continuously until all require-

NOTE: Flashing neutral (N) position indicator light
indicates that shift requirements have not been met. WARNING!You or others could be injured if you leave the
vehicle unattended with the transfer case in the
Neutral (N) position without first fully engaging the
parking brake. The transfer case Neutral (N) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
despite the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.366 STARTING AND OPERATING

Hazard Warning lights will continue to operate even
though the ignition switch is OFF.
NOTE: With extended use, the Hazard Warning lights
may discharge your battery.Hazard Light Warning Switch370 WHAT TO DO IN EMERGENCIES

• Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in

disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idling or malfunctioning operating conditions.
Intervention Regeneration Strategy – EVIC
Message Process Flow (Catalyst Full Message)
(Diesel Engines Only)
Your new Cummins 6.7L diesel meets all EPA Heavy
Duty Diesel Engine Emissions Standards for 2007 MY
(HDDE07), resulting in the lowest emitting diesel engine
ever produced. To achieve these emission standards your Dodge Chassis
Cab truck is equipped with state of the art engine and
exhaust system. The engine and exhaust aftertreatment
system work together to achieve the HDDE07 standard.
These systems are seamlessly integrated into your Dodge
truck and managed by the Cummins 6.7L engine Power-
train Control Module (PCM). The PCM manages engine
combustion to allow the exhaust system’s catalyst to trap
and burn Particulate Matter (PM) pollutants, with no
input or interaction on your part.
Additionally, the overhead console in your Dodge truck
has the ability to alert you to additional maintenance
required on your truck or engine. Refer to the following
messages that may be displayed on your Electronic
Vehicle Information Center (EVIC): MAINTAINING YOUR VEHICLE 415
