a fluid other than DEF, has experienced component
failures, or when tampering has been 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 and each
time the vehicle is started. The message will be accom-
panied by a single chime and the Malfunction Indica-
tor Light. We recommend you drive to your nearest
authorized dealer and have your vehicle serviced
immediately. If not corrected in 50 miles, vehicle will
enter the “Engine Will not restart in XXXmi Service
DEF See dealer” warning stage and message.

issue detected is not serviced during the allowed
period. Your engine will not restart unless your vehicle
is serviced by your authorized dealer. This message
will be displayed when under 1 mile until engine will
not start and each time the vehicle is started, and will
be continuously displayed. The message will be ac-
companied by a single chime. Your Malfunction Indi-
cator Light will be continuously illumined. We highly
recommend you drive to your nearest authorized

dealer. The message will be accompanied by a single
chime. Your Malfunction Indicator Light will be con-
tinuously illuminated. If the message appears and you
can not start the engine, we recommend you have your
vehicle towed to your nearest authorized dealer im-

Oil Life Reset
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required” message
will flash in the EVIC display for approximately 10
seconds after a single chime has sounded, to indicate the
next scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means the
engine oil change interval may fluctuate, dependent
upon your personal driving style.NOTE:Use the steering wheel EVIC controls for the
following procedure(s)

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.
68 STARTING AND OPERATING
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 willprovide 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,
4
STARTING AND OPERATING 69
fuel conditioners should not be required in your vehicle.
If available in your area, a high cetane “premium” diesel
fuel may offer improved cold-starting and warm-up
performance.
CAUTION!
If the “Water in Fuel Indicator Light” remains on, DO
NOT START engine before you drain the water from
the fuel filter(s) to avoid engine damage. Refer to
“Maintenance Procedures/Draining Fuel/Water Sepa-
rator Filter” in “Maintaining Your Vehicle” for fur-
ther information.
Fuel Specifications
This diesel engine has been developed to take advantage
of the high energy content and generally lower cost No.
2 Ultra Low Sulfur diesel fuel or No. 2 Ultra Low Sulfur
climatized diesel fuels.NOTE:
•If you accidentally fill the fuel tank with gasoline on
your diesel vehicle, do not start the engine. Damage to
the engine and fuel system could occur. Please call
your authorized dealer for service.
•A maximum blend of 5% biodiesel meeting ASTM
specification D-975 may be used with your diesel
engine without any adjustments to regular service
schedules.
•Commercially available fuel additives are not neces-
sary for the proper operation of your diesel engine.
•No. 1 Ultra Low Sulfur diesel fuel should only be used
where extended arctic conditions (-10°F or -23°C) exist.
70 STARTING AND OPERATING
2. Insert DEF fill adapter/nozzle into DEF tank filler
neck.NOTE:
•The DEF 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 12F
(-11C). 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.
CAUTION!
•To avoid DEF spillage, and possible damage to the
DEF tank from overfilling, do not “top off” the DEF
tank after filling.
