Adding Diesel Exhaust Fluid
• The DEF gauge (located in the instrument panel) will display the level of DEFremaining in the tank.
• Completely fill the DEF tank through the diesel exhaust fluid fill location (located behind the fuel door) at every maintenance interval or before if prompted by the
Electronic Vehicle Information Center (EVIC).
NOTE:
• Driving conditions (altitude, vehicle speed, load, etc.) will effect the amount of DEF that is used in your vehicle.
• Since DEF will begin to freeze at 12°F (-11°C), your vehicle is equipped with an automatic DEF heating system. This allows the DEF injection system to operate
properly at temperatures below 12°F (-11°C). If your vehicle is not in operation for
an extended period of time with temperatures below 12°F (-11°C), the DEF in the
tank may freeze. If the tank is overfilled and freezes, it could be damaged.
Therefore, do not overfill the DEF tank. Extra care should be taken when filling
with portable containers to avoid overfilling. Note the level of the DEF gauge in
your instrument cluster. On pickup applications, you may safely add a maximum of
2 gallons of DEF from portable containers when your DEF gauge is reading ½ full.
DEF Fill Procedure
• Remove cap from DEF tank (located behind the fuel door on drivers side of thevehicle).
• Insert DEF container or fill nozzle into DEF fill location and fill DEF tank.
NOTE:
•
The DEF gauge may take up to five
seconds to update after adding a gal-
lon or more of Diesel Exhaust Fluid
(DEF) to the DEF tank. If you have a
fault related to the DEF system, the
gauge may not update to the new
level. See your authorized dealer for
service.
• The DEF gauge may also not immedi- ately update after a refill if the tem-
perature of the DEF fluid is below
12°F (-11°C). The DEF line heater will
possibly warm up the DEF fluid and allow the gauge to update after a period of run
time. Under very cold conditions, it is possible that the gauge may not reflect the
new fill level for several drives.
• Reinstall cap onto DEF tank.
• Refer to your Diesel Supplement on the DVD for further details.

CAUTION!
•Diesel fuel will damage blacktop paving surfaces. Drain the filter into an appro-
priate container.
•Do not prefill the fuel filter when installing a new fuel filter. There is a possibility
debris could be introduced into the fuel filter during this action. It is best to install
the filter dry and allow the in-tank lift pump to prime the fuel system.
• If the “Water In Fuel Indicator Light” remains on, DO NOT START the enginebefore you drain water from the fuel filter to avoid engine damage.
EXHAUST REGENERATION
Under certain conditions, your Cummins®diesel engine and exhaust after-treatment
system may never reach the conditions required to remove the trapped particulate
matter. If this occurs, the “Exhaust System — Regeneration Required Now” message
will be displayed on the EVIC screen in your cluster and you will hear one chime to
alert you of this condition. Driving your vehicle at highway speeds for as little as
45 minutes can remedy the condition and allow the engine and exhaust after-
treatment system to remove the trapped particulate matter.
NOTE:
Under typical operating conditions, NO indications of regeneration state will be
displayed. If you do reach 80% of filter capacity, the following messages will assist
you in inducing and understanding the regeneration process.
Perform Service
Your vehicle will require emissions maintenance at a set interval. To help remind you
when this maintenance is due, the Electronic Vehicle Information Center (EVIC) will
display “Perform Service”. When the “Perform Service” message is displayed on the
EVIC it is necessary to have the emissions maintenance performed. Emissions mainte-
nance may include replacing the Closed Crankcase Ventilation (CCV) filter element, and
cleaning of the EGR Cooler. The procedure for clearing and resetting the “Perform
Service” indicator message is located in the appropriate Service Information.
Exhaust System — Regeneration Required Now
“Exhaust System—Regeneration Required Now” will be displayed on the EVIC if the
exhaust particulate filter reaches 80% of its maximum storage capacity.
Exhaust Filter XX% Full
Indicates that the Diesel Particulate Filter (DPF) is approaching full.
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.

Diesel Exhaust Fluid (DEF) Fault Warning Messages
There are four different messages which are displayed if the vehicle detects that the
DEF system has been filled with a fluid other than DEF, has experienced component
failures, or when tampering has been detected. The vehicle may be limited to a
maximum speed of 5 MPH (8 km/H) if the DEF system is not serviced within less than
250 miles (402 km) of the fault being detected.
When the DEF system needs to be serviced the following warnings will display:
•Service DEF System – See Dealer — This message will display when the fault is
initially detected, each time the vehicle is started, and periodically during driving.
The message will be accompanied by a single chime. We recommend you drive to
your nearest authorized dealer and have your vehicle serviced as soon as possible.
• 5 MPH Max Speed in 150 mi Service DEF System See Dealer — This message will
display if the DEF system has not been serviced after the “Service DEF System –
See Dealer” message is displayed. This message will continuously display until the
mileage counter reaches zero, and will be accompanied by a periodic chime. The
message will continue to countdown until it reaches zero unless the vehicle is
serviced. We recommend you drive to your nearest authorized dealer and have your
vehicle serviced immediately.
NOTE:
Under some circumstances this mileage counter may start with a value of less than
150 miles (241 km). For example, if recurring faults are detected in a time interval
of less than 40 hours, the counter may restart at the value where it stopped when a
previous fault was temporarily remedied, or at a minimum of 50 miles (80 km).
• 5 MPH Max Speed on Restart, Long Idle or Refuel Service DEF See Dealer — This
message will continuously display when the mileage counter reaches zero, and will
be accompanied by a periodic chime.
The vehicle will only be capable of a maximum speed of 5 MPH upon the first of the
following conditions to occur: • If the vehicle is shutoff and restarted.
• If the vehicle is idled for an extended period of time, approximately one hour orgreater.
• If the system detects that the level of fuel in the tank has increased.
• 5 MPH Max Speed Service DEF System See Dealer — This message will continuously
display, and will be accompanied by a periodic chime. Although the vehicle can be
started and placed in gear, the vehicle will only operate at a maximum speed of
5 MPH. Your vehicle will require towing, see your authorized dealer for service.
NOTE:
When this message is displayed, the engine can still be started. However, the vehicle
will only operate at a maximum speed of 5 MPH.
