BREAKING-IN YOUR VEHICLE
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,000 miles
(1,600 kilometers) of new vehicle operation. Vary your speed to allow
parts to adjust themselves to other parts.
Drive your new vehicle at least 500 miles (800 kilometers) before towing
a trailer. Make sure you use the specified engine oil by checking the
engine oil specification chart underEngine oilin theMaintenance
chapter.
Do not add friction modifier compounds or special break-in oils during
the first few thousand miles (kilometers) of operation, since these
additives may prevent piston ring seating. SeeEngine oilin the
Maintenancechapter of this supplement for more information on oil
usage.
DIESEL ENGINE INFORMATION
The diesel engine fuel system is a pressurized two-stage filtration system
and consists of:
•a frame-mounted diesel fuel conditioner module (DFCM) / primary
filter with an electric fuel pump and water drain,
•an engine-mounted secondary fuel filter,
•a fuel injector for each cylinder (8 total),
•a high-pressure fuel pump,
•a high-pressure fuel rail for each cylinder bank (2 total) and
•numerous high-pressure pipes from the high-pressure pump to the
rails, and rails to the injectors.
The DFCM acts as a primary fuel filter/water separator which removes
both water and impurities from the fuel. The engine mounted filter filters
finer impurities from the diesel fuel. The engine-mounted fuel filter and
the DFCM filter should be changed at the recommended service interval
or when indicated by the information displayLOW FUEL PRESSURE
message. Refer to thescheduled maintenance informationin this
supplement for more information.
The DFCM should be drained at regular intervals (recommended at
every oil change) or when indicated by the information display and water
in fuel indicator light. SeeFuel filter/water separatorin theFuel and
refuelingchapter.

Base information display procedure
1. Start with the vehicle engine fully warmed.
2. Press the Info button on the steering wheel until the information
display reads one of the following choices:
•If the DPF needs cleaning and the vehicle is warmed up, a message
requesting permission to initiate filter cleaning will be displayed
EXHST XX% FULL CLEAN Y/NorEXHAUST FILTER FULL.
Answer yes to this prompt and then follow the prompts regarding
exhaust position as needed to initiate OCR. Be sure to understand
each prompt. If you are not sure what is being asked by each prompt,
contact your authorized dealer. The display will confirm the operation
has started and when it has finished.
•If the vehicle is warmed up, the
powertrain fault indicator will
illuminate and messages
requesting permission to initiate filter cleaning will be displayed
DRIVE TO CLEAN EXHAUST FILTER+EXH OVERLOADED
CLEAN? Y/N. Answer yes to this prompt and then follow the
prompts regarding exhaust position as needed to initiate OCR. Be sure
to understand each prompt. If you are not sure what is being asked by
each prompt, contact your authorized dealer. The display will confirm
the operation has started and when it has finished. You can also drive
to clean the filter. SeeActive regenerationearlier in this chapter.
•The service engine soon light will
illuminate and the following
messagesEXH OVERLOADED
CLEAN? Y/N+REDUCED ENGINE POWERwill appear when the
system is at the point of oversaturation you will not be able to allow
cleaning . The vehicle must be serviced by an authorized dealer.
3. Once OCR starts, the engine’s rpm will rise to approximately 2,000 -
2,400 rpm and the cooling fan will increase speed; 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
OCR is complete, the engine rpm and fan will return to normal idling.
The exhaust system will remain 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 DPF, ambient
temperature, and altitude, OCR may last from 10 to 25 minutes.

Optional information display procedure
1. Start with the vehicle engine fully warmed.

of the following options appear:
•If the DPF needs cleaning and the vehicle is warmed up, you will be
prompted to hold OK to cleanExhaust xx% FullorExhaust Filter

position as needed to initiate OCR. Be sure to understand each
prompt. If you are not sure what is being asked by each prompt,
contact your authorized dealer. The display will confirm the operation
has started and when it has finished.
•When the exhaust system is
overloaded cleaning will be
allowed until a certain saturation
level. If the vehicle is warmed up and ready the powertrain fault
indicator will illuminate and you will be prompted to hold OK to clean

Press OK and then follow the prompts regarding exhaust position as
needed to initiate OCR. Be sure to understand each prompt. If you are
not sure what is being asked by each prompt, contact your authorized
