Your vehicle has the ability to alert you to additional
maintenance required on your vehicle or engine. Refer to
the following messages that may be displayed on your
Electronic Vehicle Information Center (EVIC):
•Exhaust Filter XX% Full Safely Drive at Highway
Speeds to Remedy — This message will be displayed
in the Electronic Vehicle Information Center (EVIC) if
the exhaust particulate filter reaches 80% of its maxi-
mum storage capacity. Under conditions of exclusive
short duration and low speed driving cycles, your
diesel engine and exhaust after-treatment system may
never reach the conditions required to cleanse the filter
to remove the trapped PM. If this occurs, the “Exhaust
Filter XX% Full Safely Drive at Highway Speeds to
Remedy” message will be displayed in the EVIC. If
this message is displayed, you will hear one chime
to assist in alerting you of this condition. By simply
driving your vehicle at highway speeds for up to
20 minutes, you can remedy the condition in the particulate filter system and allow your diesel engine
and exhaust after-treatment system to cleanse the filter
to remove the trapped PM and restore the system to
normal operating condition.
• Exhaust System — Regeneration In Process Exhaust
Filter XX% Full — This message indicates that the
Diesel Particulate Filter (DPF) is self-cleaning. Main-
tain your current driving condition until regeneration
is completed.
• Exhaust System — Regeneration Completed — This
message indicates that the Diesel Particulate Filter
(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
messages 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.

CAUTION!
See your authorized dealer, as damage to the exhaust
system could occur soon with continued operation.
• 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, exten-
sive exhaust after-treatment damage can occur. To
correct this condition it will be necessary to have your
vehicle serviced by your local authorized dealer.
CAUTION!
See your authorized dealer, as damage to the exhaust
system could occur soon with continued operation.
Diesel Exhaust Fluid (DEF) Warning Messages

NOTE:
• The gauge may take up to five seconds to update after
adding a gallon 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 immediately update after
a refill if the temperature 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.

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
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the heater
cord to a ground-fault interrupter protected 110–115 Volt
AC electrical outlet with a grounded, three-wire exten-
sion cord.
Its use is recommended for environments that routinely
fall below -10°F (-23°C). It should be used when the
vehicle has not been running for long periods of time and
should be plugged in two hours prior to start. Its use is
required for cold starts with temperatures under -20°F
(-28°C).
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.

WARNING!
Remember to disconnect the cord before driving.
Damage to the 110–115 Volt electrical cord could
cause electrocution.
NOTE: The block heater will require 110 Volts AC and
6.5 Amps to activate the heater element.
FUEL REQUIREMENTS
Use good quality diesel fuel from a reputable supplier in
your vehicle. Federal law requires that you must fuel this
vehicle with Ultra Low Sulfur Highway Diesel fuel
(15 ppm Sulfur maximum) and prohibits the use of Low
Sulfur Highway Diesel fuel (500 ppm Sulfur maximum) to
avoid damage to the emissions control system.
For most year-round service, No. 2 diesel fuel meeting
ASTM (formerly known as the American Society for
Testing and Materials) specification D-975 Grade S15 will
provide good performance. If the vehicle is exposed to
extreme cold (below 20°F or -7°C), or is required to operate
at colder-than-normal conditions for prolonged periods,
use climatized No. 2 diesel fuel or dilute the No. 2 diesel
fuel with 50% No. 1 diesel fuel. This will provide better
protection from fuel gelling or wax-plugging of the fuel
filters.
WARNING!
Do not use alcohol or gasoline as a fuel blending
agent. They can be unstable under certain conditions
and hazardous or explosive when mixed with diesel
fuel.
Diesel fuel is seldom completely free of water. To prevent
fuel system trouble, drain the accumulated water from
the fuel/water separator using the fuel/water separator
drain provided on the fuel filter housing. If you buy good
quality fuel and follow the cold weather advice above,
