2017 NISSAN TITAN fuel

FUEL FILTER REPLACEMENT (stage
2)
NOTE:● It is possible the “Low Fuel Pressure
Service Fuel System” message will dis-
play on the vehicle information display
after fuel filter replacement due to air
being introduced into the fuel system. ●
If the “Low Fuel Pressure Service Fuel
System” message is displayed on the
vehicle information display with the
engine running, complete a full key
cycle and restart the vehicle. If the mes-
sage is still displayed or the Malfunc-
tion Indicator Light is illuminated after
a full key cycle , it is recommended that
you visit a NISSAN dealer for service.
● For additional information on the loca-
tion of the fuel filter (stage 2) , refer to
the “Engine compartment check loca-
tions” 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 after shut- ting down the engine before loosen-
ing any fittings in the high-pressure
fuel system to allow pressure to de-
crease to a lower level.

– 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

INSTALLATION
CAUTION
Do not pre-fill the fuel filter with fuel.
Pre-filling the filter can result in debris
entering the fuel system and damaging
fuel system components.7. Install a new o-ring on the cover. Lubricate the o-ring with petroleum jelly or white
lithium grease. 8. Lubricate the inner seal on the fuel filter
element with petroleum jelly or white lithium
grease.
9. Install the fuel filter element into the fuel filter housing. Make sure the fuel filter element is
seated in the housing by pushing downward
on the top of the element.
10. Install and tighten the cover.
Cover tightening torque: 18 ft-lb (25 N·m)
11. Connect the batteries. 12. Prime the fuel system. For additional infor-
mation, refer to “Fuel system priming” in this
section.
NOTE:
If the stage 2 fuel filter element is not fully
seated in the housing, the engine can fail to
start after a fuel filter service event.

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.

WARNING
●Stay clear from the exhaust outlet and
exhaust gases. These can cause burns
or personal injury.
● To avoid the risk of personal injury or
fire, do not park the vehicle over flam-
mable materials such as dry grass,
waste paper or rags, as hot vehicle com-
ponents may ignite them.
CAUTION
To maintain maximum Diesel Particulate
Filter (DPF) performance, follow these
precautions:
● Use ultra low-sulfur fuel.
● Use an engine oil specified by NISSAN.
For additional information, refer to
“Recommended fluids/lubricants and
capacities” in the “Technical and con-
sumer information” section of this
manual. If an engine oil not specified by
NISSAN is used, it could cause DPF
malfunction or reduced fuel efficiency.
● Do not modify the DPF, muffler or ex-
haust pipe. Otherwise it could affect the
DPF performance and cause a
malfunction. ●
Do not kick or hit the DPF. The DPF has
a built-in catalyst system in the muffler.
Such an impact could cause DPF
damage.
The DPF reduces the amount of materials that
affect the environment by collecting particulate
matter included in exhaust gases. Normally, par-
ticulate matter accumulated in the DPF is auto-
matically burned and converted to harmless sub-
stances during driving. However, particulate
matter collected in the DPF cannot be burned
under the following conditions: ● When vehicle speed remains below 5 mph
(8 km/h) for a long period of time.
● When the engine is frequently stopped and
restarted within 10 minutes.
● When the vehicle is frequently used for short
journeys of 10 minutes or less.
● When the engine is frequently stopped be-
fore it has warmed up.
In these cases, it becomes difficult to burn par-
ticulate matter that has accumulated in the DPF.
As a result, the DPF warning light will
illuminate/blink and one of the following mes-
sages will display on the vehicle information dis-
play (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
For additional information, refer to the “Meters
and Gauges section of this manual.
CAUTION
●If the vehicle continues to be driven
with the DPF warning light illuminated
and without doing the regeneration
process, the fail-safe will limit the en-
gine revolutions and/or torque. In this
case, it is recommended to contact a
NISSAN dealer to have the Service Re-
generation procedure performed.

The dry paper type filter element may be cleaned
and reused. Replace it according to the mainte-
nance log shown in the “Titan Owner’s Manual.”
To remove the air cleaner filter:1. Unlatch the clips
Aand move the air
cleaner cover upward.
2. Remove the air cleaner filter.
3. Wipe the inside of the air cleaner filter hous- ing and the cover with a damp cloth. NOTE:
After installing a new air cleaner filter,
make sure the air cleaner cover is seated in
the housing and latch the clips.
WARNING
●
Operating the engine with the air
cleaner removed can cause you or oth-
ers to be burned. The air cleaner not
only cleans the air, it stops the flame if
the engine backfires. If it isn’t there, and
the engine backfires, you could be
burned. Do not drive with the air cleaner
removed, and be careful when working
on the engine with the air cleaner
removed.
● Never pour fuel into the air intake sys-
tem or attempt to start the engine with
the air cleaner removed. Doing so could
result in serious injury.
● Do not use starting fluids with this en-
gine. The use of starting fluid could
cause an explosion, fire, personal in-
jury, system or engine damage.
CAUTION
● Operating the engine with the air
cleaner removed can cause damage to
the turbocharger and major engine
damage.
● Never pour fuel into the intake or at-
tempt to start the engine with the air
cleaner removed. Doing so could result
in engine damage.
IN-CABIN MICROFILTER
The in-cabin microfilter restricts the entry of air-
borne dust and pollen particles and reduces
some objectionable outside odors. The filter is
located behind the glove box. For additional in-
formation on change intervals, refer to “Gasoline
Standard Maintenance orDiesel Standard
Maintenance in theMaintenance and sched-
ules section of this manual.
If replacement is required, it is recommended that
you visit a NISSAN dealer for this service.
