•Exhaust System — Regeneration In Process
Exhaust Filter XX% Full — Indicates that the
Diesel Particulate Filter (DPF) is self-
cleaning. Maintain your current driving
condition until regeneration is completed.
• Exhaust System — Regeneration Completed
— This message indicates that the Diesel
Particulate Filter (DPF) self-cleaning is
completed. If this message is displayed,
you will hear one chime to assist in alerting
you of this condition.
• Exhaust Service Required — See Dealer Now
— This message indicates regeneration has
been disabled due to a system malfunction.
At this point the engine Powertrain Control
Module (PCM) will register a fault code, the
instrument panel will display a MIL light.CAUTION!
See your authorized dealer, as damage to
the exhaust system could occur soon with
continued operation.
• Exhaust Filter Full — Power Reduced See
Dealer — This message indicates the PCM
has derated the engine to limit the likeli-
hood of permanent damage to the after-
treatment system. If this condition is not
corrected and a dealer service is not per-
formed, extensive exhaust after-treatment
damage can occur. To correct this condition
it will be necessary to have your vehicle
serviced by your local authorized dealer.
NOTE:
Failing to follow the oil change indicator,
changing your oil and resetting the oil change
indicator by 0 miles remaining will prevent
the diesel exhaust filter from performing it's
cleaning routine. This will shortly result in a
Malfunction Indicator Light (MIL) and re-
duced engine power. Only an authorized
dealer will be able to correct this condition.
CAUTION!
See your authorized dealer, as damage to
the exhaust system could occur soon with
continued operation.

— Wait To Start Light — If Equipped
The “Wait To Start” telltale will illuminate for
approximately two seconds when the ignition
is turned to the RUN position. It’s duration
may be longer based on colder operating
conditions. Vehicle will not initiate start until
telltale is no longer displayed. Refer to
“Starting The Engine” in “Starting And Op-
erating” for further information.
NOTE:
The “Wait To Start” telltale may not illumi-
nate if the intake manifold temperature is
warm enough.
— Water In Fuel Indicator Light —
If Equipped
The “Water In Fuel Indicator Light” will illu-
minate when there is water detected in the
fuel filters. If this light remains on, DO NOT
start the vehicle before you drain the water
from the fuel filters to prevent engine dam-
67

3. While the "Wait to Start" telltale is on, theinstrument cluster will additionally dis-
play a gauge or bar whose initial length
represents the full "Wait to Start" time
period. Its length will decrease until it
disappears when the "Wait to Start" time
has elapsed.
CAUTION!
If the “Water in Fuel Indicator Light” re-
mains on, DO NOT START engine before
you drain the water from the fuel filters to
avoid engine damage. Refer to “Draining
Fuel/Water Separator Filter” in “Dealer
Service” under “Servicing And Mainte-
nance” for further information.
4.
After the engine “Wait To Start” telltale goes
off, the engine will automatically crank.
CAUTION!
Do not crank engine for more than 15 seconds
at a time or starter motor damage may result.
Turn the ignition switch to the OFF position
and wait at least two minutes for the starter to
cool before repeating start procedure.
5. After engine start-up, check to see that there is oil pressure.
6. Allow the engine to idle about three min- utes until the manifold heaters have com-
pleted the post-heat cycle.
7. Release the parking brake and drive.
NOTE:
• Engine idle speed will automatically in- crease to 1,000 RPM and engage the Vari-
able 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 Enter-N-Go Starting Proce-
dure – Engine Manifold Air 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 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 exten-
sion 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.
STARTING AND OPERATING
124

NORMAL OPERATION — 6.7L DIESEL
ENGINE
Observe the following when the engine is
operating.
• All message center lights are off.
• Malfunction Indicator Light (MIL) is off.
• Engine oil pressure is above 10 psi(69 kPa) at idle.
• Voltmeter operation:
The voltmeter may show a gauge fluctuation
at various engine temperatures. This cycling
operation is caused by the post-heat cycle of
the intake manifold heater system. The num-
ber of cycles and the length of the cycling
operation is controlled by the engine control
module. Post-heat operation can run for sev-
eral minutes, and then the electrical system
and voltmeter needle will stabilize.
The cycling action will cause temporary dim-
ming of the headlamps, interior lamps, and
also a noticeable reduction in blower motor
speed.
Cold Weather Precautions
Operation in ambient temperature below
32°F (0°C) may require special consider-
ations. The following charts suggest these
options:
Winter Front Cover Usage
A winter front or cold weather cover is to be
used in ambient temperatures below 32°F
(0°C), especially during extended idle condi-
tions. This cover is equipped with four flaps
for managing total grille opening in varying
ambient temperatures. If a winter front or
cold weather cover is to be used the flaps
should be left in the full open position to
allow air flow to the charge air cooler and
automatic transmission oil cooler. When am-
bient temperatures drop below 0°F (-17°C)
the four flaps need to be closed. A suitable
cold weather cover is available from your
Mopar dealer.
Engine Idling
Avoid prolonged idling, long periods of idling
may be harmful to your engine because com-
bustion 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 or the truck is
driven on low engine speed drive cycles for
more than 2 hours, the system will automati-
cally enter an emissions operating mode that
will increase the engine idle speed to
900 RPM (1050 RPM for Chassis Cab).
While in this mode, which is designed to help
maintain the diesel particulate filter, the en-
gine idle speed will return to normal when the
brake pedal is applied. A small change in
engine tone or a slight change in engine
performance while accelerating may also be
noticeable at speeds below 20 mph
(32 kmh). This operating mode may last for
up to an hour of idle time, or around 20 min-
utes of driving time.
Your truck may have been ordered with an
optional voltage monitoring idle up feature. If
a load is placed on the electrical system while
the truck is in park, this feature will attempt
