Adding Diesel Exhaust Fluid
The DEF gauge (located on the instrument cluster) will
display the level of DEF remaining in the tank. Refer to
“Instrument Cluster” and “Instrument Cluster Descrip-
tions” in “Understanding Your Instrument Panel” for
further information.
NOTE:Driving conditions (altitude, vehicle speed, load,
etc.) will effect the amount of DEF that is used in your
vehicle.
Another factor is that outside temperature can affect DEF
consumption. In cold conditions, 12° F (-11° C) and
below, the DEF gauge needle can stay on a fixed position
and may not move for extended periods of time. This is
a normal function of the system.
DEF Fill Procedure
NOTE: Refer to “Fluids, Lubricants, and Genuine Parts”
in “Maintaining Your Vehicle” for the correct fluid type.
1. Remove cap from DEF tank (located on drivers side of the vehicle or in fuel door).

318 STARTING AND OPERATING

Filling The Def Tank In Cold Climates
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.
The DEF tank on these vehicles is designed with a large
amount of full reserve. So the level sensor will indicate a
Full reading even before the tank is completely full. To
put it another way, there’s additional storage capacity in
the tank above the Full mark that’s not represented in the
gauge. You may not see any movement in the reading –
even after driving up to 2,000 miles in some cases.The difference this makes varies by vehicle. Heavy-duty
pickup trucks have a 5.7-gallon tank that will display a
Full reading when about 90 percent full. This means that
drivers can consume at least 10 percent of a truly full DEF
tank without seeing any visible change in the gauge
reading. Chassis cabs have a larger 9-gallon tank, and
will display a Full reading when about 75 percent full. So
drivers can consume 25 percent of a truly full DEF tank
without seeing any visible change in the gauge reading.
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 applica-
tions, you may safely add a maximum of 2 gallons of DEF
from portable containers when your DEF gauge is read-
ing ½ full. On Chassis Cab applications a maximum of 2
gallons may be added when the DEF gauge is reading ¾
full.

STARTING AND OPERATING 321

•Temperature sensors
• SCR catalyst
• UQS Sensor
The DEF injection system and SCR catalyst enable the
achievement of diesel emissions requirements; while
maintaining outstanding fuel economy, drivability,
torque and power ratings.
Refer to “Electronic Vehicle Information Center (EVIC) or
Driver Information Display (DID)” in “Understanding
Your Instrument Panel” for system messages and warn-
ings. NOTE:
•
Your vehicle is equipped with a DEF injection system.
You may occasionally hear an audible clicking noise.
This is normal operation.
• The DEF pump will run for a period of time after
engine shutdown to purge the DEF system. This is
normal operation.

STARTING AND OPERATING 323

The condition of the air cleaner filter is monitored by the
Engine Control Module. The “SERVICE AIR FILTER”
message will display in the Electronic Vehicle Informa-
tion Center (EVIC) or Driver Information Display (DID)
when service is required. Refer to “Electronic Vehicle
Information Center (EVIC)” or “Driver Information Dis-
play (DID)” in “Understanding Your Instrument Panel”
for further information.
The “SERVICE AIR FILTER” message could be displayed
periodically. This is because engine air flow requirements
change based on driving conditions. As the filter becomes
more restrictive and air flow requirements increase the
“SERVICE AIR FILTER” message will be displayed. The
message may not be displayed in subsequent drive cycles
if the same conditions are not met. The air filter element
should be replaced within 250 miles (402 km) from the
first time this message is displayed to ensure proper
engine operation during all driving conditions.CAUTION!
Driving with a restricted air filter can cause engine
damage. Driving in dusty environments for extended
periods will lead to rapid air filter plugging. Action
should be taken as soon as the “SERVICE AIR
FILTER” message is displayed.
If the vehicle experiences a sudden loss of engine power
while being driven in heavy snow or rain, or when
plowing snow, and/or the “SERVICE AIR FILTER” mes-
sage is displayed on the EVIC/DID along with a chime
that repeats every 60 seconds, visually inspect the air
filter for snow/ice build up or extreme water saturation.
If the air filter is not damaged, remove all snow/ice and
reinstall air filter. If the air filter is damaged, replace filter
element.

MAINTAINING YOUR VEHICLE 341

•Use of biodiesel mixture in excess of 20% can nega-
tively impact the fuel filter’s ability to separate water
from the fuel, resulting in high pressure fuel system
corrosion or damage.
• Ethanol blends are not recommended or approved for
use with your Cummins diesel engine.
• In addition, commercially available fuel additives are
not necessary for the proper operation of your Cum-
mins diesel engine.
Intervention Regeneration Strategy — Message
Process Flow
The Cummins diesel engine meets all EPA Heavy Duty
Diesel Engine Emissions Standards, resulting in one of
the lowest emitting diesel engines ever produced.
To achieve these emissions standards, your vehicle is
equipped with a state-of-the-art engine and exhaust
system. The engine and exhaust after-treatment system work together to achieve the EPA Heavy Duty Diesel
Engine Emissions Standards. These systems are seam-
lessly integrated into your vehicle and managed by the
Cummins Powertrain Control Module (PCM). The PCM
manages engine combustion to allow the exhaust sys-
tem’s catalyst to trap and burn Particulate Matter (PM)
pollutants, with no input or interaction on your part.
Additionally, your vehicle has the ability to alert you to
additional maintenance required on your truck or engine.
Refer to “Electronic Vehicle Information Center (EVIC)”
or “Driver Information Display (DID)” in “Understand-
ing Your Instrument Panel” for further information.
WARNING!
A hot exhaust system can start a fire if you park over

of special dyes for diagnosing fluid leaks. Avoid using
transmission sealers as they may adversely affect seals.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New
Vehicle Limited Warranty.
Fluid Level Check
It is best to check the fluid level when the transmission is
at normal operating temperature (170-180°F / 77-82°C for
68RFE transmission, or 158-176°F / 70-80°C for AS69RC
transmission). This normally occurs after at least 15 miles
(25 km) of driving. At normal operating temperature the
fluid cannot be held comfortably between the fingertips.
You can read the transmission sump temperature in theEVIC/DID screen (refer to “Electronic Vehicle Informa-
tion Center [EVIC]” or “Driver Information Display
[DID]” for further information).
Use the following procedure to check the transmission
fluid level properly:
1. Monitor the transmission temperature using the
EVIC/DID screen, and operate the vehicle as required
to reach the normal operating temperature. If the
transmission is not functioning properly, or the vehicle
cannot be driven, see the NOTE and CAUTION below
about checking the fluid level at colder temperatures.
2. Park the vehicle on level ground.
3. Run the engine at normal idle speed for at least 60 seconds, and leave the engine running for the rest of
this procedure.
4. Fully apply the parking brake and press the brake pedal.

Oil Change Indicator System — Cummins Diesel
Your vehicle is equipped with an engine oil change
indicator system. This system will alert you when it is
time to change your engine oil by displaying the words
“Oil Change Due” on your Electronic Vehicle Informa-
tion Center (EVIC) or Driver Information Display (DID).
The oil change reminder will remind the owner to change
the engine oil every 15,000 miles or 500 hours, whichever
comes first, except for the Chassis Cab models and
Pickup models configured with optional B20 capability
that are using B20 biodiesel, which are 12,500 miles or 400
hours, whichever comes first. Failure to change the
engine oil per the maintenance schedule can result in
internal engine damage.
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other
than your authorized dealer, the message can be reset byreferring to the steps described under “Electronic Vehicle
Information Center (EVIC)” or “Driver Information Dis-
play (DID)” in “Understanding Your Instrument Panel”
for further information.
Replace the engine oil and oil filter every 15,000 miles
(24 000 km) or six months, or sooner if prompted by the
oil change indicator system. Under no circumstances
should oil change intervals exceed 15,000 miles (24
000 km) or six months, whichever comes first.
NOTE:
•
Under no circumstances should oil change intervals
exceed 15,000 miles (24,000 km) or six months or 500
Hours, whichever comes first.
• Replace the engine oil and oil filter every 12,500 miles
(20 000 km) when running B20 fuel (Chassis Cab
Only).
