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)

When the engine is running, the MIL may flash to
alert serious conditions that could lead to
immediate loss of power or severe catalytic
converter damage. The vehicle should be serviced
by an authorized dealer as soon as possible if this
occurs.
Electronic Stability Control (ESC) Active
Warning Light — If Equipped
This warning light will indicate when the
ESC system is Active. The ESC Indicator
Light in the instrument cluster will come
on when the ignition is placed in the ON/
RUN or ACC/ON/RUN position, and when ESC is
activated. It should go out with the engine running.
If the ESC Indicator Light comes on continuously
with the engine running, a malfunction has been
detected in the ESC system. If this warning light
remains on after several ignition cycles, and the
vehicle has been driven several miles (kilometers)
at speeds greater than 30 mph (48 km/h), see an
authorized dealer as soon as possible to have the
problem diagnosed and corrected.
The ESC OFF Indicator Light and the ESC Indi -
cator Light come on momentarily each time the
ignition is placed in the ON/RUN or ACC/ON/
RUN position.
The ESC system will make buzzing or clicking
sounds when it is active. This is normal; the
sounds will stop when ESC becomes inactive.
This light will come on when the vehicle is in an
ESC event.
Electronic Stability Control (ESC) OFF
Warning Light — If Equipped
This warning light indicates the ESC is off.
Each time the ignition is turned to ON/
RUN or ACC/ON/RUN, the ESC system
will be on, even if it was turned off previously.
LaneSense Warning Light — If Equipped
The LaneSense system provides the
driver with visual and steering torque
warnings when the vehicle starts to drift
out of its lane unintentionally without the
use of a turn signal.
When the LaneSense system senses a lane drift
situation, the LaneSense indicator changes
from solid green to solid yellow.
When the LaneSense system senses the lane
has been approached and is in a lane departure
situation, the LaneSense indicator changes
from solid white/green to flashing yellow
Ú page 156.
Low Washer Fluid Warning Light —
If Equipped
This warning light will illuminate when the
windshield washer fluid is low
Úpage 338.
WARNING!
A malfunctioning catalytic converter, as
referenced above, can reach higher
temperatures than in normal operating
conditions. This can cause a fire if you drive
slowly or park over flammable substances such
as dry plants, wood, cardboard, etc. This could
result in death or serious injury to the driver,
occupants or others.
CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the
vehicle control system. It also could affect fuel
economy and driveability. If the MIL is flashing,
severe catalytic converter damage and power
loss will soon occur. Immediate service is
required.

“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.
4

22_DPF_OM_EN_USC_t.book Page 115

116STARTING AND OPERATING

1. With the transmission in PARK, the parking brake applied, and the engine running, turn
on the Cruise Control, then push the SET (-)
button.

2. The engine RPM will go up to 1,100 RPM. To increase the RPM, push and hold the RES (+)
button and the idle speed will increase to
approximately 1,500 RPM. To decrease the
RPM, push and hold the SET (-) button and the
idle speed will decrease to approximately
1,100 RPM.
3. To cancel the Idle–Up feature, either push the CANCEL button, push the ON/OFF button, or
press the brake pedal.
NOISE
Diesel engines can create noises that may seem
as a concern. The nature of a diesel engine is
compression ignition where compressed air and
fuel are mixed and ignited. Weather, barometric
pressure, altitude and temperature will affect how
fuel is ignited in the engine. Engines will sound
different from day to day or previous model years.
Clicking, ticking, or light knocking is normal and will
change from day to day, as the engine breaks in,
and can vary with changes in ambient
temperature; this is normal. Diesel equipped
vehicles also have an exhaust after treatment
system to reduce emissions utilizing a Diesel
Particulate Filter (DPF) and a Selective Reduction
Catalyst (SCR). The SCR reduces Nox using the
Diesel Exhaust Fluid (DEF) system. DEF is injected directly into the SCR through an dosing module.
This process will create a clicking sound and at
times, will make noise even with the vehicle shut
off. This is normal as the DEF dosing module is
purging DEF. If at any time the check engine light is
on, please visit an authorized dealer.
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 allow the lubricating oil and coolant
to carry excess heat away from the combustion
chamber, bearings, internal components, and
turbocharger. This is especially important for
turbocharged, charge air-cooled engines. Refer to
the following chart for proper engine shutdown:

118STARTING 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.
DIESEL PARTICULATE FILTER (DPF)
M
ANUAL REGENERATION — IF EQUIPPED
On equipped Chassis Cabs, a manual regeneration
can be enable through the instrument cluster. The
manual regeneration will allow the DPF to
complete a regeneration, lowering the soot level
without having to drive the vehicle. The vehicle
must be in PARK to access this feature, and the
fuel level must be over 12.5% full. A message
displaying the time left on the regeneration will
appear on the instrument cluster, and the
instrument cluster will display the soot level
Ú page 81.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and
permits quicker starts in cold weather. Connect the
cord to a standard 110-115 Volt AC electrical
outlet with a grounded, three-wire extension cord.
The engine block heater cord is routed behind the
front bumper and accessible through the right hole
of the air dam.
The engine block heater must be plugged in at
least one hour to have an adequate warming effect
on the engine.
It includes a removable cap that is secured by a
tethered strap. It also has a c-clip that is used for
storage when not in use for the Winter months.
During Winter months, remove the heater cord
wiring assembly from itself on the c-clip.
NOTE:The block heater will require 110 Volt 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.
ENGINE BREAK-IN RECOMMENDATIONS —
GASOLINE ENGINE
A long break-in period is not required for the engine
and drivetrain (transmission and axle) in your
vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles (100 km),
speeds up to 50 or 55 mph (80 or 90 km/h) are
desirable.
While cruising, brief full-throttle acceleration within
the limits of local traffic laws contributes to a good
break-in. Wide-open throttle acceleration in low
gear can be detrimental and should be avoided.
The engine oil installed in the engine at the factory
is a high-quality energy conserving type lubricant.
Oil changes should be consistent with anticipated
climate conditions under which vehicle operations
will occur. For the recommended viscosity and
quality grades Ú page 404.
NOTE:A new engine may consume some oil during its first
few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in
CAUTION!
Never use Non-Detergent Oil or Straight Mineral
Oil in the engine or damage may result.

22_DPF_OM_EN_USC_t.book Page 118

STARTING AND OPERATING121
(Continued)
(Continued)
NOTE:For optimum braking power it is recommended to
use the exhaust brake while in TOW/HAUL mode.

The exhaust brake feature can also be used to
reduce the engine warm-up time. To use the exhaust
brake as a warm-up device, the vehicle must be
stopped or moving less than 5 mph (8 km/h), the
Exhaust Brake Indicator must be on, and the coolant
temperature must be below 180°F (82°C) and
ambient temperature below 60°F (16°C).

Automatic “Smart” Exhaust Brake
Automatic “Smart” Exhaust Brake technology
delivers smoother, less aggressive exhaust
braking characteristics during downhill descents.
Although it can apply full exhaust braking force if
needed, Automatic “Smart” Exhaust Brake may
not apply obvious braking if the vehicle speed is
not increasing. Automatic “Smart” Exhaust Brake
is intended to maintain vehicle speed, while Full
Exhaust Brake is intended to reduce vehicle speed.
Automatic “Smart” Exhaust Brake can be enabled
by pushing the exhaust brake button (on the center
stack) again anytime after the normal Full Exhaust
Brake has been turned on. The “Exhaust Brake Indicator” in the instrument cluster display will
change from Yellow to Green when Automatic
“Smart” Exhaust Brake is enabled. Pushing the
exhaust brake button again will toggle the exhaust
brake mode to off.AUTOMATIC TRANSMISSION
You must press and hold the brake pedal while
shifting out of PARK.
CAUTION!
Use of aftermarket exhaust brakes is not recom
-
mended and could lead to engine damage.
WARNING!
It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing
the brake pedal, the vehicle could accelerate
quickly forward or in reverse. You could lose
control of the vehicle and hit someone or
something. Only shift into gear when the
engine is idling normally and your foot is firmly
pressing the brake pedal.
The transmission may not engage PARK if the
vehicle is moving. Always bring the vehicle to a
complete stop before shifting to PARK, and
verify that the transmission gear position indi -
cator solidly indicates PARK (P) without
blinking. Ensure that the vehicle is completely
stopped, and the PARK position is properly
indicated, before exiting the vehicle.
Unintended movement of a vehicle could
injure those in or near the vehicle. As with all
vehicles, you should never exit a vehicle while
the engine is running. Before exiting a vehicle,
always come to a complete stop, then apply
the parking brake, shift the transmission into
PARK, turn the engine OFF, and remove the
key fob. When the ignition is in the LOCK/OFF
(key removal) position, (or, with Keyless Enter
‘n Go™, when the ignition is in the OFF posi -
tion) the transmission is locked in PARK,
securing the vehicle against unwanted move -
ment.
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 use the PARK position as a substitute
for the parking brake. Always apply the
parking brake fully when exiting the vehicle to
guard against vehicle movement and possible
injury or damage.
Your vehicle could move and injure you and
others if it is not in PARK. Check by trying to
move the gear selector out of PARK with the
brake pedal released. Make sure the trans -
mission is in PARK before exiting the vehicle.
