ENGINE BREAK-IN RECOMMENDATIONS
The diesel engine does not require a break-in period due
to its construction. Normal operation is allowed, provid-
ing the following recommendations are followed:
•Warm up the engine before placing it under load.
• Do not operate the engine at idle for prolonged
periods.
• Use the appropriate transmission gear to prevent
engine lugging.
• Observe vehicle oil pressure and temperature indica-
tors.
• Check the coolant and oil levels frequently.
• Vary accelerator pedal position at highway speeds
when carrying or towing significant weight. NOTE:
Light duty operation such as light trailer towing
or no load operation will extend the time before the
engine is at full efficiency. Reduced fuel economy and
power may be seen at this time.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil
changes should be consistent with anticipated climate
conditions under which vehicle operations will occur.
The recommended viscosity and quality grades are
shown under “Fluids, Lubricants and Genuine Parts”,
under “Maintaining Your Vehicle” in this manual. NON-
DETERGENT OR STRAIGHT MINERAL OILS MUST
NEVER BE USED.
8 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!(Continued)
•When leaving the vehicle, always remove the key
fob and lock your vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Children should be
warned not to touch the parking brake, brake pedal
or the gear selector/shift lever. Do not leave the key
fob in or near the vehicle (or in a location accessible
to children), A child could operate power windows,
other controls, or move the vehicle.
Extreme Cold Weather
This vehicle has three heating elements; one engine block
heater (a resistance heater installed in the water jacket of
the engine) and two transmission heaters (one resistance heater installed under the oil reservoir of the hydraulic
actuation system and one on the differential cover of the
transmission). They require a 110–115 Volt AC electrical
outlet with a grounded, three-wire extension cord. Their
use is recommended for environments that routinely fall
below -10°F (-23°C). They should be used when the
vehicle has not been running overnight or longer periods
and should be plugged in two hours prior to start. Their
use is required for cold starts with temperatures under
-17°F (-27°C).
NOTE:
The engine is designed to work at an ambient
temperature ranging from -22°F to + 122°F (-30°C to +
50C°). Rubber, pipes, timing belt cover and electronic
devices are not designed to work out of this range.
In the case of LOW temperature after Starting, the Auto-
mated Manual Transmission may not be able to engage
first gear. In this case a message Shift not allowed
appears. In this situation use the engine block heater.
56 STARTING AND OPERATING

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/TRANSMISSION HEATER — IF
EQUIPPED
To ensure reliable starting/operating at these tempera-
tures, use of an externally powered electric engine block/
transmission heater (available from your authorized
dealer) is recommended.
The engine block heater warms engine coolant and
permits quicker starts in cold weather. The transmission
heaters warm gearbox oil and hydraulic actuation system
oil to operate in cold weather. Connect the heater cord to
a ground-fault interrupter protected 110–115 Volt AC
electrical outlet with a grounded, three-wire extension
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 overnight or longer periods

STARTING AND OPERATING 61

•During low-speed driving conditions in first gear,
vehicle momentum changes may feel exaggerated in
response to changes in accelerator pedal position. This
behavior is normal and is similar to other vehicles
equipped with manual transmissions.
• At low speeds you may hear mechanical noises similar
to a manual transmission as the transmission changes
gears. These noises are normal and will not damage
the transmission.
• Very aggressive driving may result in some clutch
odor. A warning message will display in the EVIC if
cool down actions are needed.
• Before and after the engine is started, you may hear a
hydraulic pump for a short period of time. This noise
is normal and will not damage the transmission. •
During extremely cold temperatures, the transmission
will not operate if the oil temperature is -22°F (-30°C)
or below. When transmission actuation oil temperature
is lower than -22°F (-30°C), engine start will not be
allowed by PCM. For this reason the block heater is
recommended below -17°F (-27°C). Normal operation
will resume once the transmission temperature has
risen to a suitable level.
Manual (M) (Manual Mode)
In the MANUAL (M) position the driver is responsible
for choosing the best gear ratio to engage, depending on
driving conditions.
NOTE: Do not press the brake and accelerator pedals at
the same time. Use only one foot to operate the brake and
accelerator.

Biodiesel Fuel Requirements
A maximum blend of 5% biodiesel meeting ASTM speci-
fication D975 is recommended for use with your diesel
engine. If frequent operation with Biodiesel blends that
are between 6% and 20% (B6–B20) is desired, the main-
tenance schedule is subject to shorter intervals.
The oil and filter change along with fuel filter replace-
ment is subject to shorter intervals when operating your
engine on biodiesel greater than 5%. Do not use biodiesel
greater than 20%.
For regular use of biodiesel blends between 6% and 20%
(B6–B20) it is important that you understand and comply
with these requirements. Refer to the “Maintenance
Chart” in the “Maintenance Schedules” section for fur-
ther direction.
CAUTION!
Failure to comply with Oil Change requirements for
vehicles operating on biodiesel blends between 6%
and 20% (B6–B20) will result in premature engine
wear. Such wear is not covered by the New Vehicle
Limited Warranty.
Biodiesel is a fuel produced from renewable resources
typically derived from animal fat, rapeseed oil (Rapeseed
Methyl Ester (RME) base), or soybean oil (Soy Methyl
Ester (SME or SOME) base).
Biodiesel fuel has inherent limitations which require that
you understand and adhere to the following requirements
if you use blends of Biodiesel between 6% and 20%
(B6–B20). There are no unique restrictions for the use of B5.

which is recommended for all operating temperatures.
This engine oil improves low temperature starting and
vehicle fuel economy.
Materials Added To Engine Oil
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental addi-
tives.
Engine Oil Filter
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information. The
engine oil filter should be changed at every engine oil
change.
Disposing Of Used Engine Oil And Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact your authorized dealer, service
station or governmental agency for advice on how and
where used oil and oil filters can be safely discarded in
your area.
Engine Air Cleaner Filter
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
CAUTION!
All air entering the engine intake must be filtered.
The abrasive particles in unfiltered air will cause
rapid wear to engine components.
