– Never smoke or allow sparks orflames (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.
∙ Depending on the circumstance, die- sel fuel is flammable. When inspect-
ing or performing service or repairs
on the fuel system, to reduce the pos-
sibility of fire and resulting severe
personal injury, death, or property
damage, never smoke or allow sparks
or flames (such as pilot lights, electri-
cal switches, or welding equipment) in
the work area.
∙ Do not vent the fuel system on a hot engine; this can cause fuel to spill
onto a hot exhaust 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.

∙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.

∙ 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.

DRAINING WATER
WARNING
To avoid the risk of personal injury or
fire, drain diesel fuel into an approved
container and safely dispose of in ac-
cordance with local environmental
regulations.
CAUTION
Continuing vehicle operation without
properly draining could cause serious
damage to the engine.1. Shut the engine off.
2. Place a large drain pan under the drain
valve
A.
3. Turn the drain valve counterclockwise
1/4 turn to open.
4. Drain the filter sump until clear fuel is visible. If draining the stage 1 fuel filter
housing, drain until fuel reduces to a
trickle.
5. Turn the drain valve clockwise1/4 turn
to close.
FUEL SYSTEM PRIMING
WARNING
The fuel pump, high-pressure fuel lines,
and fuel rail contain very high-pressure
fuel. To reduce the possibility of per-
sonal injury, never loosen any fittings
while the engine is running. NOTE:
∙ It is not necessary to vent air from the
high-pressure fuel system before
starting the engine.
∙ Upon ignition on the electric lif t pump
will run until the fuel system is primed
or 90 seconds, whichever comes first.
Af ter a filter change or running the fuel tank
dry, complete the following: 1. Key ON vehicle for 90 seconds to prime the fuel system. Af ter 90 seconds, crank
the engine for a maximum of 30 sec-
onds or until the engine fires. If it does
not fire, verif y the following.
– Confirm fuel level is not empty.
– Water in fuel drain valve is closed.
– Stage 1 filter housing shell is fully seated on module and stage 2 cap is
properly seated on module.
– Stage 1 shell O-ring and stage 2 cap O-ring are properly installed and not
damaged.
LDI2898

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.
Introduction1-3

WARNING
∙ Do not use starting fluid, such asether, in the air intake system. Use of
such fluid could cause engine dam-
age and/or personal injury.
∙ Do not add gasoline, alcohol or kero- sene to diesel fuel.
CAUTION
∙ Read all starting instructions carefullyprior to starting your vehicle.
∙ When starting the engine in ex- tremely cold temperatures, it is rec-
ommended to allow the engine to idle
for several minutes before driving the
vehicle.
∙ The use of the factory engine block heater (if so equipped) will assist in
starting the engine in extreme cold
ambient temperatures. For additional
information, refer to the “Starting and
driving” section of the Titan Owner’s
Manual. Engine warming
This message may display during cold
starting conditions. It is a reminder that
during cold starting conditions the engine
may not crank immediately af ter pushing
the ignition switch, and could take up to
approximately 4 seconds to crank. The
brake pedal must be depressed during this
wait period.
1. Verif y the shif t lever is in the P (Park) or N (Neutral) position. P (Park) is recom-
mended. The shif t lever cannot be moved out
of P (Park) and into any of the other
gear positions if the ignition switch
is in the OFF position.
The starter is designed not to oper-
ate if the shif t lever is in any of the
driving positions.
2. There are two ways to start your diesel engine:
∙ Push the ignition switch to the ON position, and wait up to 4 seconds for
the glow plug to warm up. Depress
the brake pedal and push the ignition
switch to start the engine.
or
∙ Depress the brake pedal and push the ignition switch to start the en-
gine. Keep the brake pedal de-
pressed until the glow plug warms
up. This could take up to 4 seconds.
The vehicle will start.
The starter is designed to not en-
gage until the glow plugs have had
sufficient time to warm up. During
cold temperatures this could take up
to 4 seconds.

STARTING THE DIESEL ENGINE
3-2Starting and Stopping the Engine

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.

AUTOMATIC REGENERATION
Automatic regeneration occurs when the
control module detects the exhaust filter
needs to be cleaned. This is a normal pro-
cess and will not typically require any op-
erator interaction.
If the automatic regeneration is not able to
clean the exhaust filter the vehicle informa-
tion display will display the following mes-
sages in order of severity:∙ Exhaust Filter Overloaded See Owner’s Manual for Drive Pattern
∙ Exhaust Filter Overloaded Engine Power Reduced See Owner’s Manual
∙ Exhaust Filter Overloaded Immediate Service Required
The instructions for these messages in the
“Meters and gauges” section of this manual
will inform the driver to modif y their driving
pattern to enable the automatic regenera-
tion process.
