GETTING TO KNOW YOUR INSTRUMENT PANEL91
By simply driving your vehicle at highway speeds
for as little as 45 minutes, you can remedy the
condition in the particulate filter system and
allow your Cummins® diesel engine and
exhaust after-treatment system to remove the
trapped PM and restore the system to normal
operating condition.
Exhaust System — Regeneration In Process
Exhaust Filter XX% Full — Indicates that the DPF
is self-cleaning. Maintain your current driving
condition until regeneration is completed.
Exhaust System — Regeneration Completed —
This message indicates that the 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.
Exhaust Filter Full — Power Reduced See
Dealer — This message indicates the PCM has
derated the engine to limit the likelihood of
permanent damage to the after-treatment
system. If this condition is not corrected and a
dealer service is not performed, extensive
exhaust after-treatment damage can occur. To
correct this condition it will be necessary to have
your vehicle serviced by an 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 reduced engine power. Only an authorized
dealer will be able to correct this condition.
Cold Ambient Derate Mode Messages
The vehicle will display messages when a derate
(engine power reduction) is activated to protect the
engine during start-up in cold ambient
temperatures.
Engine Power Reduced During Warm-up — This
message will display during start-up when the
ambient temperature is between 10°F (-12°C)
and -10°F (-23°C).
Engine Power Reduced Up To 30 Sec (Seconds)
During Warm-up — This message will display
during start-up when the ambient temperature
is between -10°F (-23°C) and -25°F (-32°C).
Engine Power Reduced Up To 2 Min (Minutes)
During Warm-up — This message will display
during start-up when the ambient temperature
is -25°F (-32°C) and below.
Your vehicle is equipped with an engine warm
up protection feature that may limit engine
performance after cold starting at low ambient
temperatures. The length of time engine speed
is limited is dependent upon engine coolant
temperature. Engine speed may be briefly
limited to 1,000 RPM after starting with coolant
temperature below freezing conditions, and
may be limited to 1,000 RPM for up to approxi -
mately two minutes under more severe cold
conditions.
Coolant Low — This telltale will turn on to indi -
cate the vehicle coolant level is low
Ú page 341.CAUTION!
See an authorized dealer, as damage to the
exhaust system could occur soon with continued
operation.
CAUTION!
See an authorized dealer, as damage to the
exhaust system could occur soon with continued
operation.

3. Push the ENGINE START/STOP button a second time to change the ignition to the RUN
position.
4. Push the ENGINE START/STOP button a third time to return the ignition to the OFF position.
Keyless Enter ‘n Go™ Starting Procedure —
Engine Manifold Air Temperature 0°F To
66°F (–18°C to 19°C)
NOTE:The temperature displayed in the instrument
cluster does not necessarily reflect the engine
manifold air temperature Ú page 81. When
engine temperatures fall below 66°F (19°C) the
“Wait To Start” telltale will remain on indicating the
intake air heater system is active.
Follow the steps in the “Normal Starting”
procedure except:

1. Pushing the engine start button with the driver’s foot on the brake will move the
ignition from OFF or ACC to RUN, and will
illuminate the "Wait to Start" telltale. The
engine will not immediately crank, this is
normal operation.

2. The “Wait to Start" telltale will remain on for a period of time that varies depending on the
engine temperature. 3. While the "Wait to Start" telltale is on, the
instrument cluster will additionally display 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.
4. After the engine “Wait to Start” telltale goes off, the engine will automatically crank.
5. After engine start-up, check to see that there is oil pressure.
6. 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 will 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” telltale goes out, reset the intake air
heater by turning the ignition switch to the OFF
position for at least 5 seconds and then back
ON. Repeat steps 1 through 6 of “Keyless
Enter ‘n Go™ Starting Procedure – Engine Mani -
fold Air Temperature 0°F To 66°F (–18°C to
19°C).”
EXTREME COLD WEATHER
The Cummins® Turbo 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.
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 Ú page 347.
CAUTION!
Do not crank engine for more than 25 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.

22_DPF_OM_EN_USC_t.book Page 110

STARTING AND OPERATING115
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.
NOTE:High-speed, no-load running of a cold engine can
result in excessive white smoke and poor engine
performance. No-load engine speeds should be
kept under 1,000 RPM during the warm-up period,
especially in cold ambient temperature conditions.
Your vehicle is equipped with an engine warm-up
protection feature that may limit engine
performance after cold starting at low ambient
temperatures. The length of time engine speed is
limited is dependent upon engine coolant
temperature. Engine speed may be briefly limited
to 1,000 RPM after starting with coolant
temperature below freezing conditions, and may
be limited to 1,000 RPM for up to approximately
two minutes under more severe cold conditions.
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
improve 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 or the truck is driven
on low engine speed drive cycles for more than two
hours, the system will automatically enter an
emissions operating mode that will increase the
engine idle speed to 900 RPM (1,050 RPM for
Chassis Cab). While in this mode, which is
designed to help maintain the Diesel Particulate
Filter, the engine 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 km/h). This operating mode may last for up to an hour of
idle time, or around 20 minutes 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 to maintain normal
system voltage by automatically increasing engine
idle speed. You may notice several consecutive
increases in idle speed, up to a maximum of
1,450 RPM, as the system will attempt to utilize
the smallest increase in idle speed necessary to
maintain normal system voltage. The idle speed
will return to normal when either the electrical load
is removed, or when the brake pedal is applied.
NOTE:For instrument cluster display messages related to
the vehicle's exhaust system Ú
page 81.
Idle-Up Feature
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 after-treatment system to
not properly regenerate. Extended periods of idle
time should be avoided.
The Idle-Up feature uses the Cruise Control buttons
to increase engine idle speed and quickly warm the
vehicle's interior.
