WARNINGS
your vehicle becomes limited to engine idle
only once stopped. In these conditions, be
cautious where you stop your vehicle
because you may not be able to drive long
distances or maintain highway speeds until
you refill or replace the diesel exhaust fluid. Tampering with or disabling selective
catalytic reduction system results in
severe vehicle performance
limitation including eventual speed limiting
to 5 mph (5 km/h). The information display shows a series of
messages about the amount of diesel
exhaust fluid available. A systems check
displays messages indicating the amount
of diesel exhaust fluid available or displays
a warning message indicating the
approximate distance remaining as the
fluid in the diesel exhaust fluid tank nears
empty. See
Information Messages
(page 64). As the diesel exhaust fluid level
nears empty, the warning
symbol displays and a series of
tones and messages starting at
500 mi
(800 km) remaining before diesel exhaust
fluid is depleted. The warning symbol and
messages continue until you refill the
diesel exhaust fluid tank. Continued driving without refilling results
in the following actions as required by the
California Air Resources Board (CARB) and
the U.S. Environmental Protection Agency
(EPA):
•
Within a preset distance to empty,
speed is limited upon vehicle restart.
Prior to this occurring a message
appears in the information display.
• Further vehicle operation without
refilling the diesel exhaust fluid tank
causes the engine to enter an idle-only
condition. This only occurs upon vehicle
refueling or at an extended idle. A
message indicates the required actions
to resume normal operation. It is
required to add a minimum of
0.5 gal
(1.9 L) of diesel exhaust fluid to the
tank to exit the idle-only condition, but
your vehicle is still in the speed-limiting
mode until you refill the tank
completely.
Note: For either vehicle speed limiting or
idle-only condition, normal vehicle operation
resumes when you refill the diesel exhaust
fluid tank.
Note: When filling the diesel exhaust fluid
tank from empty, there may be a short delay
before detecting the increased level of fluid.
The increased level detection must occur
before your vehicle returns to full power.
Diesel Exhaust Fluid Guidelines
and Information
• Use only diesel exhaust fluid that
carries the American Petroleum
Institute (API) certified diesel exhaust
fluid trademark or ISO 22241.
• Do not put diesel exhaust fluid in the
diesel fuel tank.
• Do not overfill the diesel exhaust fluid
tank.
• Diesel exhaust fluid is corrosive.
• Do not re-use the diesel exhaust fluid
container once it is emptied.
98
F650750 (TBC), enUSA, First Printing Fuel and RefuelingE163176
•
Avoid spilling diesel exhaust fluid on
painted surfaces, carpeting or plastic
components. Immediately wipe away
any diesel exhaust fluid that has spilled
with a damp cloth and water. If it has
already crystallized, use warm water
and a sponge.
• Store diesel exhaust fluid out of direct
sunlight and in temperatures between
23°F (-5°C) and 68°F (20°C).
• Diesel exhaust fluid freezes below 12°F
(-11°C)
.
• Do not store the diesel exhaust fluid
bottle in your vehicle. If it leaks it could
cause damage to interior components
or release an ammonia odor inside your
vehicle.
• Diesel exhaust fluid is non-flammable,
non-toxic, colorless and water-soluble
liquid.
• The system has a diesel exhaust fluid
quality sensor. Dilution of diesel
exhaust fluid or use of any other liquid
in the SCR system leads to a diesel
exhaust fluid system fault, eventually
leading to the vehicle only operating in
idle-only mode.
• Do not dilute diesel exhaust fluid with
water or any other liquid.
• An ammonia odor may be smelled
when the cap is removed or during
refill. Refill diesel exhaust fluid in a well
ventilated area. Typical Diesel Exhaust Fluid Usage
When Using the Power Take Off (PTO) Continuous PTO use—Minimal PTO use
0–7,800 mi (0– 12,550 km)
Contaminated Diesel Exhaust
Fluid or Inoperative Selective
Catalytic Reduction System
Maintaining the purity of diesel exhaust
fluid is important to avoid malfunctions in
the selective catalytic reduction system.
If you remove the diesel exhaust fluid for
tank repair, do not use the same fluid to
refill the tank. You can no longer guarantee
the purity of the diesel exhaust fluid. The system has a diesel exhaust
fluid quality sensor. Selective
catalytic reduction systems are
sensitive to contamination of the diesel
exhaust fluid. If the selective catalytic
reduction system becomes contaminated
or inoperative, the diesel exhaust fluid light
illuminates and exhaust fluid system fault
messages appear in the information
display.

F650750 (TBC), enUSA, First Printing Fuel and RefuelingE163176
Continued driving without replacing diesel
exhaust fluid or having the selective
catalytic reduction system repaired results
in the following actions as required by the
California Air Resources Board (CARB) and
U.S. Environmental Protection Agency
(EPA):
•
Within a preset distance to empty,
speed is limited upon vehicle restart.
Prior to this occurring a message
appears in the information display.
• Further vehicle operation without
replacing contaminated diesel exhaust
fluid causes the engine to enter an
idle-only condition. This only occurs
upon vehicle refueling, vehicle idling in
park for 1 hour, or engine shutdown for
10 minutes or more and is indicated by
a message in the information display
indicating required actions to resume
normal operation.
Note: For either vehicle speed limiting or
idle-only condition, normal vehicle operation
resumes when you repair the contaminated
system. To service a contaminated or
inoperative system, see an authorized
dealer.
REFUELING - 6.8L WARNINGS
Fuel vapor burns violently and a fuel
fire can cause severe injuries.
Read and follow all the instructions
on the pump island.
When refueling always shut the
engine off and never allow sparks or
open flames near the fuel tank filler
valve. Never smoke or use a cell phone
while refueling. Fuel vapor is extremely
hazardous under certain conditions. Avoid
inhaling excess fumes. WARNINGS
Stay outside your vehicle and do not
leave the fuel pump unattended
when refueling your vehicle.
Keep children away from the fuel
pump; never let children pump fuel.
Wait at least 10 seconds before
removing the fuel pump nozzle to
allow any residual fuel to drain into
the fuel tank. Stop refueling after the fuel pump
nozzle automatically shuts off for the
second time. Failure to follow this
will fill the expansion space in the fuel tank
and could lead to fuel overflowing. Do not remove the fuel pump nozzle
from its fully inserted position when
refueling.
Use the following guidelines to avoid
electrostatic charge build-up when filling
an ungrounded fuel container:
•
Place approved fuel container on the
ground.
• Do not fill a fuel container while it is in
the vehicle (including the cargo area).
• Keep the fuel pump nozzle in contact
with the fuel container while filling.
• Do not use a device that would hold
the fuel pump handle in the fill position.
Fuel Filler Cap WARNINGS
The fuel system may be under
pressure. If you hear a hissing sound
near the fuel filler inlet, do not refuel
until the sound stops. Otherwise, fuel may
spray out, which could cause serious
personal injury.

in the system, it begins to restrict the filter.
You need to periodically clean the soot
that gathers inside the filter. You can clean
the soot in two different ways, passive
regeneration and active regeneration. Both
methods occur automatically and require
no actions from the driver. During either
one of these regeneration methods, you
may notice a change in exhaust tone. At
certain times, the information display
shows various messages related to the
diesel particulate filter. See Information
Displays (page 62). Passive Regeneration
In passive regeneration, the exhaust
system temperature and constituents
automatically clean the filter, or reduce
the soot level, by burning (oxidizing) the
soot. Cleaning occurs naturally because of
normal engine operating conditions (at
varying levels, due to driving patterns).
Diesel Particulate Filter Maintenance
You must properly maintain your vehicle's
diesel particulate filter in order for it to
function properly.
Do not disregard the following maintenance messages: Action and Description
Message
This may degrade vehicle performance and could lead to
engine damage that may not be covered by the vehicle
Warranty.
Exhaust filter overloaded
Drive to clean
Exhaust filter at limit
Clean now
Failure to perform active or Operator
Commanded Regeneration when
instructed could result in a clogged diesel
particulate filter. If your diesel particulate
filter fills beyond the regeneration
threshold, your vehicle disables the ability
for active and Operator Commanded
Regeneration. This could result in
irreversible damage to the filter requiring
replacement that your warranty may not
cover. If your vehicle is not equipped with
Operator Commanded Regeneration,
check with your dealer for availability. Once the diesel particulate filter is full of
exhaust particles, the engine control
module commands the exhaust system to
clean the filter through a process called
active regeneration. Active regeneration
requires the engine computer to raise the
exhaust temperature to eliminate the
particles. During cleaning, the particles
convert to harmless gasses. Once cleaned
the diesel particulate filter continues
trapping exhaust particles.
The regeneration process operates more
efficiently when you safely operate your
vehicle at least 30 mph (48 km/h) with a
steady pedal for approximately 20 minutes
to complete the process. The frequency
and duration of regeneration fluctuates by
how you drive your vehicle, outside air
temperature, and altitude. For most driving,
106
F650750 (TBC), enUSA, First Printing Fuel and Refueling
regeneration frequency varies from
100–500 miles (161–805 km) between
occurrences and each occurrence lasts
9–
35 minutes. You can usually reduce the
duration of regeneration if you maintain a
constant speed above 30 mph (48 km/h).
When the engine control module detects that the diesel particulate filter is nearly
full of particulates and you are not operating your vehicle in a manner to allow
effective automatic cleaning, the following messages appear in the information
display: Action and Description
Message
This message appears as a reminder for you to drive in order
to clean the diesel particulate filter. If you operate your vehicle
in a manner to allow effective automatic cleaning, the
information display shows a cleaning exhaust filter message,
which is the normal regeneration process. See Information
Messages (page 64).
Exhaust filter overloaded
Drive to clean
You can also choose Operator
Commanded Regeneration to clean the
exhaust system at this point. See How to
start Operator Commanded Regeneration
later in this chapter.
If you are not able to drive in a manner that
allows effective automatic cleaning (active
regeneration) or you choose to perform
regeneration of the diesel particulate filter
(cleaning) while at idle (stationary), then
Operator Commanded Regeneration
would need to be performed. See Operator
Commanded Regeneration later in this
chapter.
Operator Commanded Regeneration
(If Equipped)
If your vehicle is operated with significant
stationary operation, low speed drive
cycles less than 25 mph, short drive cycles,
a drive time is less than 10 - 15 minutes or
the vehicle does not fully warm up, passive
and active regeneration may not
sufficiently clean the diesel particulate
filter system. Operator Commanded Regeneration allows you to manually start
regeneration of the diesel particulate filter
at idle (while stationary) to clean the filter.
If you are not sure whether your vehicle is
equipped with this feature, contact an
authorized dealer.
When to Carry Out Operator Commanded
Regeneration
You can use the Operator Commanded
Regeneration feature if any of the following
messages appear in the information
display and:
•
You are not able to drive in a manner
that allows effective automatic
cleaning (active regeneration).
• You choose to manually start the
regeneration (cleaning) of the diesel
particulate filter manually while the
vehicle is idle (stationary). Message

WARNING
Failure to comply with the following
instructions for Operator
Commanded Regeneration may
result in fire, serious injury, death or
property damage. Before you start operator commanded
regeneration, do the following:
•
Place your vehicle in Park (P) with the
parking brake set on stable, level
ground.
• You must park your vehicle outside of
any structure.
• Your vehicle must be 10– 15 feet (3–5
meters) away from any obstructions
and must be away from materials that
can easily combust or melt (for
example, paper, leaves, petroleum
products, fuels, plastics and other dry
organic material). •
Make sure there is a minimum of 1/8
tank of fuel.
• Make sure all fluids are at proper levels.
How to Start Operator Commanded
Regeneration WARNING
Stay clear of exhaust tip during
regeneration. You or others can be
burned.
Note:
You cannot use the Operator
Commanded Regeneration until the diesel
particulate filter load percentage has
reached 100% (Full). The diesel particulate
filter load percentage fluctuates up and
down when driving your vehicle due to active
and passive regenerations.
Note: During the use of Operator
Commanded Regeneration, you may
observe a light amount of white smoke. This
is normal. You cannot use the Operator
Commanded Regeneration if the
service engine soon light is
illuminated.

Once Operator Commanded Regeneration
starts, the engine ’s rpm raises to
approximately 2000 rpm and the cooling
fan speed increases; you will hear a change
in audible sound due to the fan and engine
speed increase.
It is not necessary to open the hood on the
engine compartment. Once Operator
Commanded Regeneration is complete,
the engine rpm and fan returns to normal
idling. The exhaust system remains very
hot for several minutes even after
regeneration is complete. Do not reposition
the vehicle over materials that could burn
until the exhaust system has had sufficient
time to cool. Depending on the amount of
soot collected by the diesel particulate
filter, ambient temperature, and altitude,
Operator Commanded Regeneration lasts
approximately 30 minutes. Operator Commanded Regeneration
with Automatic Regeneration Control
(If Equipped)
If your vehicle is operated with significant
stationary operation, low speed drive
cycles less than 25 mph (40 km/h), short
drive cycles, drive time less than 15 minutes
or the vehicle does not fully warm up,
passive and active regeneration may not
sufficiently clean the diesel particulate
filter system. You can switch off automatic
regeneration until better driving conditions
are available, for example steady high
driving. You can then switch automatic
regeneration back on to clean the diesel
particulate filter.

How to Interrupt or Cancel Operator
Commanded Regeneration
If you need to cancel the Operator
Commanded Regeneration, pressing the
brake, accelerator, or shutting off the
vehicle stops the procedure. Depending on
the amount of time you allowed the
Operator Commanded Regeneration to
operate, soot may not have had sufficient
time to be eliminated, but the exhaust
system and exhaust gas may still be hot.
If you shut your vehicle off during Operator
Commanded Regeneration, you will notice
turbo flutter. This is a normal consequence
caused by shutting off a diesel engine
during boosted operation and is considered
normal. Filter Service and Maintenance
Over time, a slight amount of ash builds
up in the diesel particulate filter, which is
not removed during the regeneration
process. The filter may need to be removed
for ash cleaning at approximately 120,000
miles (193,000 km) or greater (actual
mileage can vary greatly depending upon
engine/vehicle operating conditions) and
replaced with a new or remanufactured
(ash cleaned) part. The filter may need to
be replaced at approximately 250,000
miles (400,000 km) depending upon
vehicle operating conditions.
In both cases, the engine control
system illuminates a service light
to inform you that your vehicle
requires service.
If there are any issues with the diesel
particulate filter system, the engine control
system illuminates a service light to inform
you that your vehicle requires service.
