Preventive maintenance is the easiest and
least expensive type of maintenance. Keep
records of regularly scheduled mainte-
nance and follow the maintenance sched-
ule recommendations outlined in the Titan
Owner’s Manual.
Use the correct fuel, lubricating oil, and
coolant in your engine. Blending engine oil
with fuel is prohibited for engines with an
af tertreatment system. For additional in-
formation, refer to the “Capacities and
specifications” section of 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. Reading this supplement will fa-
miliarize you and other operators of the
vehicle with the unique maintenance and
operating procedures that will prolong the
life of the diesel engine and related sys-
tems.
ENGINE BREAK-IN
RECOMMENDATIONS
∙ Warm up the engine before operating itunder load
∙ Do not operate the engine at idle for extended periods
∙ Prevent engine lugging by selecting the appropriate transmission gear
∙ Monitor the vehicle oil pressure and temperature gauges
∙ Check fluid levels frequently (Oil & Cool- ant)
∙ 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
observed for the first 6,000 miles. The en-
gine run-in is improved by operating the
vehicle under load.
DIESEL FUEL SYSTEM
The diesel engine fuel system is a pressur-
ized two-stage filtration system and con-
sists 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 cylin- der 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 lef t
bank fuel rail, and fuel rails to fuel injec-
tors.
GENERAL INFORMATION
1-2Introduction

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 recom-
mended service interval or when indicated
by the information display. For additional
information, refer to “Maintenance and
schedules” and “Instruments and controls”
sections of the Titan Owner’s Manual.
The water/fuel separator should be
drained when indicated by illumination of
the water in fuel warning light.
NOTE:
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 and has the potential for fuel sys-
tem damage.ENGINE PROTECTION MODE
The diesel engine in this vehicle is equipped
with electronically controlled fuel and
emission systems. Both systems monitor
engine temperatures and pressures, and
then modif y 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 ex-
tended periods of time, and the service en-
gine soon light is illuminated, have the sys-
tem checked. It is recommended 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 interval beyond the recom-
mended interval can negatively affect en-
gine performance, fuel economy and en-
gine life. For additional information, refer to
the “Do-it-yourself ” section of this manual.
GLOW PLUGS
The diesel engine glow plug system con-
sists 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 en-
ergized varies depending on engine and
environmental conditions. The required
time for the glow plugs to be energized
decreases as coolant temperature in-
creases. For additional information, refer to
the “Starting and stopping the engine” sec-
tion of this manual.
