key ignition NISSAN TITAN 2019 Owner´s Manual

∙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.

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

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.
