3. Allow the engine to idle for at least 30 sec-onds after starting. Do not race the engine
while warming it up. Drive at moderate
speed for a short distance first, especially in
cold weather.
In cold weather, keep the engine running for
a minimum of 2–3 minutes before shutting it
off. Starting and stopping the engine over a
short period of time may make the vehicle
more difficult to start.
SWITCHING ENGINE OFF
Push the ignition to the off position.
To prolong the engine life (especially after ex-
tended high speed, high ambient temperature, or
during heavy load operation, such as trailering) , it
is recommended that a hot engine be idled for
3–5 minutes before shutting down. This allows
the turbocharged engine to cool down.
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 and 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 ob-
served for the first 6,000 miles. The engine run-in
is improved by operating the vehicle under load.
REMOTE START (if so equipped)
CAUTION
Laws in some jurisdictions prohibit use of
remote start. Vehicles started with the remote start require the
ignition switch to be placed in the ON position
before the shift lever can be moved from the P
(Park) position. To place the ignition switch to the
ON position, follow these steps:
1. Make sure that the Intelligent Key is on you.
2. Apply the brake.
3. Press the ignition switch once to the ON position.
For additional information, refer to “NISSAN In-
telligent Key®” in the “Pre-driving checks and
adjustments” section of your owner’s manual.
ENGINE BLOCK HEATER (if so
equipped)
The power cable to operate the heater is avail-
able as a service part from an authorized NISSAN
dealer.
For additional information, refer to “Engine block
heater” in the “Starting and Driving” section of
your owner’s manual.

REMOVAL
NOTE:
Leaving the housing un-installed from the
module for extended periods of time could
cause the fuel tank to drain through the
stage 1 fuel filter module.1. Push the ignition switch to the OFF position and wait 2 minutes before disconnecting the
battery.
2. Disconnect the batteries.
3. Clean the area around the stage 1 fuel filter. 4. Drain the fuel filter housing. For additional
information, refer to “Draining water” in this
section.
5. Close the water-in-fuel drain.
6. Disconnect the wiring harness
Afrom the
water-in-fuel sensor.
7. Remove the fuel filter housing
Bfrom the
module
C.
NOTE:
It may be necessary to use a screwdriver in
the slots provided to remove the fuel filter
element from the housing.8. Remove the fuel filter element
Dby lifting it
out of the fuel filter housing.
9. Remove and discard the sealing o-ring
E
from the fuel filter housing.

– Wear appropriate eye protection andprotective equipment as high-
pressure fuel spray can penetrate the
skin.
– Never smoke or allow sparks or flames (such as pilot lights, electrical
switches, or welding equipment) in
the work area. Never allow diesel fuel
to spill onto a hot exhaust manifold
which can cause a fire.
● Batteries can emit explosive gases. To
reduce the possibility of personal injury,
always ventilate the compartment be-
fore servicing the batteries. To reduce
the possibility of arcing, remove the
negative (-) battery cable first and at-
tach the negative (-) battery 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 protec-
tion when using compressed air. Flying
debris and dirt can cause personal
injury.CAUTION
Clean all around the filter area before dis-
assembly. Dirt or contaminants can dam-
age the fuel system.
REMOVAL
WARNING
● Depending on the circumstance, fuel is
flammable. When inspecting or per-
forming service or repairs on the fuel
system, to reduce the possibility of fire
and resulting severe personal injury,
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 position and wait 2 minutes before disconnecting the
battery.
2. Disconnect the batteries.
3. Clean the area around the stage 2 fuel filter. 4. Remove the cover
Afrom the stage 2 fuel
filter.
NOTE:
Remove the cover slowly to avoid fuel spill-
age. 5. Remove the fuel filter element
Cfrom the
cover by hand.
6. Remove and discard the sealing o-ring
B
from the cover.
INSPECTION
Inspect the fuel filter housing and cover for
cracks, passage blockages, and other damage. If
damage is found, replacement is mandatory.
It is recommended that you visit a NISSAN dealer
for this service.

DRAINING WATER
WARNING
To avoid the risk of personal injury or fire,
drain diesel fuel into an approved con-
tainer and safely dispose of in accordance
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 counterclockwise1/4
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 personal
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 start-
ing the engine.
● Upon ignition on the electric lift pump
will run until the fuel system is primed
or 90 seconds, whichever comes first. Purge the air out of the fuel system after refilling a
completely empty fuel tank by the following pro-
cedure:
1. Turn the key ON for 90 seconds to prime the fuel system. After 90 seconds, crank the
engine for a maximum of 30 seconds or until
the engine starts. If the engine does not
start, repeat this step.
2. When the engine does start, it may operate erratically and with increased noise levels for
a few minutes. This is a normal condition as
air is being removed from the system.
NOTE:
It is possible for a warning or indicator light
to illuminate due to air entering the fuel
system. If this happens, it is recommended
that you visit a NISSAN dealer for service.

AUTOMATIC REGENERATION
Automatic regeneration occurs when the control
module detects the exhaust filter needs to be
cleaned. This is a normal process and will not
typically require any operator interaction.
If the automatic regeneration is not able to clean
the exhaust filter the vehicle information display
will display the following messages in order of
severity:● Exhaust Filter Overloaded See Owners
Manual for Drive Pattern
● Exhaust Filter Overloaded Engine Power
Reduced See Owners Manual
● Exhaust Filter Overloaded Immediate Ser-
vice Required
The instructions for these messages in the “Me-
ters and Gauges” section of this manual will
inform the driver to modify their driving pattern to
enable the automatic regeneration process.

LOCK position before servicing drive belt.
The engine could rotate unexpectedly.
1. Visually inspect the belt for signs of unusual wear, cuts, fraying or looseness. If the belt is
in poor condition or is loose, have it re-
placed. It is recommended that you visit a
NISSAN dealer for this service.
2. Have the belt checked regularly for condi- tion and tension in accordance with the
maintenance schedule found in the “Titan
Owner’s Manual”.
