∙If the “Low Fuel Pressure: See Owner’s
Manual” message is displayed on the
vehicle information display with the
engine running, complete a full key
cycle (turn the vehicle off and wait
2 minutes) and restart the vehicle. If
the message is still displayed or the
Malfunction Indicator Light is illumi-
nated af ter a full key cycle , it is rec-
ommended that you visit a NISSAN
dealer for service.
∙ For additional information on the lo-
cation of the fuel filter (stage 2), refer
to the “Engine compartment check
locations” in this section.
WARNING
∙ The fuel system (fuel pump, high pres- sure fuel lines, fuel rail, injectors) con-
tain very high pressure fuel. To avoid
the risk of personal injury or fire;
– Do not loosen any fittings while the engine is running.
– Wait at least 10 minutes af ter shut- ting down the engine before loos-
ening any fittings in the high-
pressure fuel system to allow
pressure to decrease to a lower
level. – Wear appropriate eye protection
and protective equipment as high-
pressure fuel spray can penetrate
the skin.
– Never smoke or allow sparks or flames (such as pilot lights, electri-
cal switches, or welding equip-
ment) in the work area. Never allow
diesel fuel to spill onto a hot ex-
haust manifold which can cause a
fire.
∙ Batteries can emit explosive gases. To reduce the possibility of personal in-
jury, always ventilate the compart-
ment before servicing the batteries.
To reduce the possibility of arcing, re-
move the negative (-) battery cable
first and attach the negative (-) bat-
tery cable last.
∙ When using a steam cleaner, wear safety glasses or a face shield, as well
as protective clothing. Hot steam can
cause serious personal injury.
∙ Wear appropriate eye and face pro- tection when using compressed air.
Flying debris and dirt can cause per-
sonal injury.
CAUTION
Clean all around the filter area before
disassembly. Dirt or contaminants can
damage the fuel system.
REMOVAL
WARNING
∙ Depending on the circumstance, fuelis flammable. When inspecting or per-
forming service or repairs on the fuel
system, to reduce the possibility of
fire and resulting severe personal in-
jury, death, or property damage, never
smoke or allow sparks or flames (such
as pilot lights, electrical switches, or
welding equipment) in the work area.
∙ Do not bleed the fuel system of a hot engine; this can result in fuel spilling
onto a hot exhaust manifold, which
can cause a fire.
1. Push the ignition switch to the OFF po- sition and wait 2 minutes before dis-
connecting the battery.
2. Disconnect the lef t and right side bat- teries.

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.

Instrument Panel2-7

CAUTION
If the engine does not start, place the
ignition switch in the OFF position and
wait 10 seconds before cranking again,
otherwise the starter could be
damaged.3. Allow the engine to idle for at least 30 seconds af ter starting. Do not race
the engine while warming it up. Drive at
a moderate speed for a short distance
first, especially in cold weather.
In cold weather, keep the engine run-
ning for a minimum of 2–3 minutes
before shutting it off. Starting and
stopping the engine over a short pe-
riod of time may make the vehicle
more difficult to start.
SWITCHING ENGINE OFF
Push the ignition switch to the OFF posi-
tion.
To prolong the engine life (especially af ter
extended high speed, high ambient tem-
perature, or during heavy load operation,
such as trailering), it is recommended that
a hot engine be idled for 3–5 minutes be-
fore shutting down. This allows the turbo-
charged engine to cool down.
ENGINE BREAK-IN
RECOMMENDATIONS
∙ Warm up the engine before operating it under 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 and coolant).
∙ Vary the throttle position at highway speeds when carrying weight or tow-
ing.
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.
REMOTE ENGINE START (if so
equipped)
CAUTION
Laws in some jurisdictions prohibit use
of Remote Engine Start.
Vehicles started with the Remote Engine
Start require the ignition switch to be
placed in the ON position before the shif t
lever can be moved from the P (Park) posi-
tion. To place the ignition switch in the ON
position, follow these steps: 1. Make sure that the Intelligent Key is on you.
2. Apply the brake.
3. Push the ignition switch once to the ON position.
For additional information, refer to “NISSAN
Intelligent Key®” in the “Pre-driving checks
and adjustments” section of the Titan
Owner’s Manual.
Starting and Stopping the Engine3-3

CAUTION
Be sure to remove any old gasket mate-
rial remaining on the sealing surface of
the engine. Failure to do so could lead to
an oil leak and engine damage.7. Fill the new filter with clean engine oil.
8. Coat the gasket on the new filter with clean engine oil.
9. Screw on the oil filter until a slight resis- tance is felt, then tighten an additional
3/4 turn.
10. Start the engine and check for leakage around the oil filter. Correct as required.
11. Install skid plate in reverse order of re- moval.
12. Turn the engine off and wait more than 10 minutes. Check the oil level. Add en-
gine oil if necessary.
CAUTION
Your vehicle may require more frequent
maintenance if it operates on biodiesel
blends between 6% and 10% (B6 and
B10). To avoid damage to your vehicle,
the oil, oil filter, and fuel filter will need
to be replaced af ter a shorter time in-
terval than if your vehicle was operat-
ing on pure petroleum-based diesel.
For additional information, refer to the
“Maintenance and schedules” section in
the Titan Owner’s Manual.
FUEL FILTER REPLACEMENT (stage
1 and 2)
A NISSAN dealer can change the stage 1
