Do not drain the fuel/water separator filter when the
engine is running.
430 MAINTAINING YOUR VEHICLE

CAUTION!
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.
NOTE:The fuel filter and water separator assembly is
located on the driver’s side of the engine. The best access
to the water drain valve is through the driver’s side
wheel well.
NOTE:If water is detected in the water separator while
the engine is running or while the key is in the on
position, the water in fuel light will illuminate and an
audible chime will be heard 5 times. At this point you
should stop the engine and drain the water from the
separator.If the water in fuel light comes on and a single chime is
heard while you are driving, or with the key in the ON
position, there may be a problem with your water
separator wiring or sensor. See your authorized dealer
for service.
Upon proper draining of the water from the fuel filter, the
water in fuel light will remain illuminated for approxi-
mately 10 seconds. If the water was drained while the
engine was running, the water in fuel light may remain
on for approximately 3 minutes.
NOTE:Care should be taken in disposing of used fluids
from your vehicle. Used fluids, indiscriminately dis-
carded, can present a problem to the environment. Con-
tact your local dealer, service station, or government
agency for advice on recycling programs and for where
used fluids and filters can be properly disposed of in
your area.

Drain a small amount from the fuel/water separator
filter monthly or when the WATER IN FUEL indicator
lamp is on. Turn the drain valve, located on the bottom of
the filter, counterclockwise and allow any accumulated
water to drain into an approved container. Leave the
drain valve open until all water and contaminants have
been removed. Close the drain valve, by turning it
clockwise, when clean fuel is visible.
NOTE:The Fuel / Water separator drain valve is
located on the bottom of the fuel filter housing.
If more than a couple ounces of fuel has been drained,
follow the directions below for “Priming if the engine has
run out of fuel.”WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.
Priming if the engine has run out of fuel
1. Add a substantial quantity of fuel to the tank 5 to 10
gallons (19L to 38L).
2. Crank the engine for 1 to 2 seconds. If the engine does
not start, then release the key or starter button back to the
RUN position (do not turn the key back to the OFF
position). The electric fuel transfer pump will continue to
run and purge air from the system for about 25 seconds.
After 25 seconds, attempt to start the engine again.
432 MAINTAINING YOUR VEHICLE

3. Start the engine using the Normal Starting Procedure.
4. Repeat the procedure if the engine does not start.
CAUTION!
Do not engage the starter motor for more than 15
seconds at a time. Allow two minutes between the
cranking intervals.
NOTE:The engine may run rough until the air is forced
from all the fuel lines.
CAUTION!
Diesel fuel will damage black top paving surfaces.
Drain the filter into an appropriate container.
WARNING!
Do not use alcohol or gasoline as a fuel blending
agent. They can be unstable under certain conditions
and be hazardous or explosive when mixed with
diesel fuel.
CAUTION!
Due to lack of lubricants in alcohol or gasoline, the
use of these fuels can cause damage to the fuel
system.

NOTE:A maximum blend of 5% biodiesel, meeting
ASTM specification D-6751 may be used with your
Cummins Diesel equipped vehicle. Use of bio-diesel
mixture in excess of 5% can negatively impact the on-
engine fuel filter’s ability to separate water from the fuel,
resulting in high pressure fuel system corrosion or dam-
age.
NOTE:As sufficient testing as not been completed,
ethanol blends are not recommended or approved for use
with your Cummins Diesel equipped vehicle.
NOTE:In addition, commercially available fuel addi-
tives are not necessary for the proper operation of your
Cummins Diesel equipped vehicle.Intervention Regeneration Strategy – EVIC
Message Process Flow (Catalyst Full Message)
(6.7L Diesel Engines Only)
Your new Cummins 6.7L diesel meets all EPA Heavy
Duty Diesel Engine Emissions Standards, resulting in the
lowest emitting diesel engine ever produced.
To achieve these emission standards your vehicle is
equipped with state of the art engine and exhaust system.
The engine and exhaust aftertreatment system work
together to achieve the EPA Heavy Duty Diesel Engine
Emissions Standards. These systems are seamlessly inte-
grated into your vehicle and managed by the Cummins
6.7L engine 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.
434 MAINTAINING YOUR VEHICLE

Additionally, the overhead console in your vehicle has
the ability to alert you to additional maintenance re-
quired on your truck or engine. Refer to the following
messages that may be displayed on your Electronic
Vehicle Information Center (EVIC):
WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.
Perform Service
The 6.7L Cummins engine utilizes a Closed Crankcase
Ventilation (CCV) system, EGR Valve and a EGR Cooler.
This system filters and recycles gasses produced in thecrankcase during the normal combustion process. Per-
form Service will be displayed on the overhead console of
your vehicle if the CCV filter, EGR Valve and EGR Cooler
is due for required maintenance. The CCV filter is located
on the top of the engine valve cover. For additional
information, see your local authorized dealer.
Catalyst Full See Owner Manual
Catalyst Full See Owner Manual will be displayed on the
overhead console of your vehicle if the exhaust particu-
late filter reaches 80% of its maximum storage capacity.
Under conditions of exclusive short duration and low
speed driving cycles, your Cummins engine and exhaust
aftertreatment system may never reach the conditions
required to remove the trapped PM, if this occurs Cata-
lyst Full See Owner Manual will be displayed on the
overhead console in your vehicle. If this message is
displayed you will hear one chime to assist in alerting
you of this condition.

Catalyst Stat::::::::::80%
Catalyst Stat::::::::::80% will replace the message Catalyst
Full See Owner Manual after it is displayed for one
minute. The engine Powertrain Control Module (PCM)
will continue to monitor the amount of particulate matter
trapped in the particulate filter. This message indicates
the percentage of the particulate filter capacity that has
been used.
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 engine
and exhaust Aftertreatment system to remove the
trapped PM and restore the system to normal operating
condition.
Catalyst Stat:::::::::::80%, 90%, 99%
Catalyst Stat:::::::::::80%, 90%, 99% If you are unable to
drive your vehicle under these conditions for an ex-
tended period of time after the initial warning notifica-
tion, the Engine PCM will continue to monitor the
particulate filter and will display the progression of
particulate filter usage (80, 90, 99%) on the EVIC message
center.
CATALYST FULL SERVICE REQD
If the particulate filter reaches 99% of it’s capacity the
overhead console in your vehicle will chime twice and
display the message CATALYST FULL SERVICE REQD.
At this point the engine PCM will register a fault code,
the instrument panel will display a MIL light and the
engine PCM will derate the truck reducing its horse-
power and torque output.
436 MAINTAINING YOUR VEHICLE

The PCM derates the engine in order to limit the likeli-
hood of permanent damage to the aftertreatment system.
If this condition is not corrected and a dealer service is
not performed, extensive exhaust aftertreatment damage
can occur. In order to correct this condition it will be
necessary to have the truck serviced by your local
authorized dealer.
Maintenance Free Batteries
The top of the maintenance free batteries are perma-
nently sealed. You will never have to add water, nor is
periodic maintenance required.
NOTE:Replacement batteries should both be of equal
capacity to prevent damage to the vehicle’s charging
system.
WARNING!
•Battery fluid is a corrosive acid solution and can
burn or even blind you. Don’t allow battery fluid
to contact your eyes, skin or clothing. Don’t lean
over a battery when attaching clamps. If acid
splashes in eyes or on skin, flush the area imme-
diately with large amounts of water.
•Battery gas is flammable and explosive. Keep
flame or sparks away from the battery. Don’t use a
booster battery or any other booster source with an
output greater than 12 volts. Don’t allow cable
clamps to touch each other.
•Battery posts, terminals and related accessories
contain lead and lead compounds. Wash hands
after handling.
