Preventive maintenance is the easiest and least
expensive type of maintenance. Keep records of
regularly scheduled maintenance and follow the
maintenance schedule recommendations out-
lined in the “Titan Owner’s Manual”.
Use the correct fuel, lubricating oil, and coolant in
your engine. Blending engine oil with fuel is pro-
hibited for engines with an aftertreatment system.
For additional information, refer to the “Capaci-
ties and Specifications” section in this manual.
A NISSAN dealership knows your vehicle. When
you require any service or have any questions,
they will be glad to assist you with the extensive
resources available to them.
DIESEL ENGINE OPERATION
The operation of the diesel engine in your new
vehicle varies from the operation of traditional
gasoline engines found in other vehicles. Read-
ing this supplement will familiarize you and other
operators of the vehicle with the unique mainte-
nance and operating procedures that will prolong
the life of the diesel engine and related systems.
ENGINE BREAK-IN
RECOMMENDATIONS
●Warm up the engine before operating it un-
der load
● Do not operate the engine at idle for ex-
tended periods
● Prevent engine lugging by selecting the ap-
propriate transmission gear
● Monitor the vehicle oil pressure and tem-
perature gauges
● Check fluid levels frequently (Oil & Coolant)
● Vary the throttle position at highway speeds
when carrying weight or towing
NOTE:
Extended light or no load operation will
extend the time before the engine reaches
its full efficiency. If the engine is operated
in this manner, reduced fuel economy and
power may be observed.
The aforementioned procedure should be ob-
served for the first 6,000 miles. The engine run-in
is improved by operating the vehicle under load.
DIESEL FUEL SYSTEM
The diesel engine fuel system is a pressurized
two-stage filtration system and consists of: ● A frame-mounted primary (stage 1) fuel filter
containing water/fuel separator, electric fuel
pump, and water in fuel drain valve
● An engine-mounted secondary (stage 2)
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)
● High-pressure fuel lines from the high-
pressure fuel pump to the right bank fuel rail,
right bank fuel rail to the left bank fuel rail,
and fuel rails to fuel injectors.
The stage 1 fuel filter separates water and filters
impurities from the fuel. The stage 2 fuel filter
filters finer impurities from the diesel fuel. The
stage 1 and stage 2 fuel filters should be
changed at the recommended service interval or
when indicated by the information display. For
additional information, refer to the “Titan Owner’s
Manual”.
GENERAL INFORMATION
1-2Introduction

The water/fuel separator should be drained when
indicated by illumination of the water in fuel warn-
ing light.
Proper fuel filter maintenance and prompt water
draining when the water in the fuel filter warning
light illuminates is essential to prevent damage to
fuel injection system components. Ignoring the
water in fuel warning light can cause your vehicle
to go into a reduced power mode.
ENGINE PROTECTION MODE
The diesel engine in this vehicle is equipped with
electronically controlled fuel and emission sys-
tems. Both systems monitor engine temperatures
and pressures, and then modify engine operation
accordingly. It is normal for the diesel engine to
operate under these modified conditions for
short durations of time. If the engine operates
under the modified conditions for extended peri-
ods of time, and the service engine soon light is
illuminated, have the system checked. It is recom-
mended that you visit a NISSAN dealer for this
service as soon as possible.
LUBRICATION SYSTEM
It is important to change the engine oil at the
recommended service intervals to maintain oil
viscosity. Extending the oil and filter change inter-
val beyond the recommended interval can nega-
tively affect engine performance, fuel economyand engine life. For additional information, refer to
the “Do-it-yourself” section of this manual.
GLOW PLUGS
The diesel engine glow plug system consists of:
● Eight Glow Plugs (one per cylinder)
● Glow Plug Control Module- Uses input from
the Engine Coolant Temperature Sensor
The glow plugs are energized momentarily when
the ignition is first turned on. The length of time
that the glow plugs are energized varies depend-
ing on engine and environmental conditions. The
required time for the glow plugs to be energized
decreases as coolant temperature increases. For
additional information, refer to the “Starting and
stopping the engine” section of this manual.
DIESEL PARTICULATE FILTER (DPF)
SYSTEM
Your vehicle is equipped with a diesel particulate
filter in the exhaust system. The diesel particulate
filter reduces carbon emissions by trapping ex-
haust particulates (soot) before they reach the
tailpipe. You must properly maintain your diesel
particulate filter in order for it to function properly.
Regeneration of the diesel particulate filter oc-
curs automatically during operation above 5 mph
(8 km/h) and requires no actions from the driver.
If you do a lot of idling or stop and go driving, pay attention to maintenance messages that alert you
when you need to drive to activate the automatic
regeneration process. For additional information,
refer to the ”Automatic Regeneration” in the “Do-
it-yourself” section of this manual.
SELECTIVE CATALYTIC REDUCTION
SYSTEM
Your vehicle is equipped with a selective catalytic
reduction system designed to reduce emission
levels of nitrogen oxides from the exhaust of your
diesel engine. This system relies on the use of
Diesel Exhaust Fluid (DEF) that you must replen-
ish at certain intervals. Failure to maintain proper
DEF levels or if the DEF becomes contaminated
will result in vehicle speed limitation to 5 mph. For
additional information, refer to the ”Meters and
gauges” and “Capacities and Specifications”
sections of this manual.
