Introduction WARNINGS Throughout this guide, you will find warnings identified by the symbol . Warnings remind you to be especially careful to reduce the risk of personal injury. NEW VEHICLE BREAK-IN 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 km) 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 km) before towing a trailer. Make sure you use the specified engine oil by checking the engine oil specification chart under Engine oil in the Maintenance and Specifications 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. See Engine oil in the Maintenance and Specifications chapter 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 message center LOW FUEL PRESSURE message. Refer to the scheduled maintenance information in this supplement for more information. 3 2011 Diesel (eco) Supplement, 5th Printing USA (fus)

WARNINGS
Throughout this guide, you will find warnings identified by the
symbol
. Warnings remind you to be especially careful to reduce the
risk of personal injury.
NEW VEHICLE BREAK-IN
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 km) 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 km) before towing a
trailer. Make sure you use the specified engine oil by checking the engine
oil specification chart under
Engine oil
in the
Maintenance and
Specifications
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. See
Engine oil
in the
Maintenance and Specifications
chapter 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 message center
LOW FUEL PRESSURE
message. Refer to the
scheduled maintenance information
in this
supplement for more information.
