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.
Starting and Stopping the Engine3-3

DIESEL FUEL-FILLER CAP
WARNING
●Diesel fuel is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seriously
injured if it is misused or mishandled.
Always stop the engine and do not
smoke or allow open flames or sparks
near the vehicle when refueling. ●
Do not attempt to top off the fuel tank
after the fuel pump nozzle shuts off
automatically. Continued refueling may
cause fuel overflow, resulting in fuel
spray and possibly a fire.
● Use only an original equipment type
fuel-filler cap as a replacement. It has a
built-in safety valve needed for proper
operation of the fuel system and emis-
sion control system. An incorrect cap
can result in a serious malfunction and
possible injury. It could also cause
the
Malfunction Indicator Light
(MIL) to come on.
● Do not use starting fluids with this en-
gine. It is equipped with an intake air
heater. The use of starting fluid could
cause an explosion, fire, personal in-
jury, system or engine damage.
● Do not fill a portable fuel container in
the vehicle or trailer. Static electricity
can cause an explosion of flammable
liquid, vapor or gas in any vehicle or
trailer. To reduce the risk of serious
injury or death when filling portable fuel
containers:
– Always place the container on the ground when filling. – Do not use electronic devices when
filling.
– Keep the pump nozzle in contact with the container while you are fill-
ing it.
– Use only approved portable fuel con- tainers for flammable liquid.
CAUTION
●For additional information, refer to the
“Malfunction Indicator Light (MIL)” in
the “Instruments and Controls” section
of the Titan Owner’s Manual.
● If fuel or Diesel Exhaust Fluid (DEF) is
spilled on the vehicle body, flush it away
with water to avoid paint damage

WARNING
Always follow the instructions below. Fail-
ure to do so could result in damage to the
charging system and cause personal
injury.1. If the booster battery is in another vehicle, position the two vehicles to bring their bat-
teries near each other.
Do not allow the two vehicles to touch.
2. Apply the parking brake. Move the shift lever to P (Park) . Switch off all unnecessary elec-
trical systems (lights, heater, air conditioner,
etc.) . 3. Ensure the vent caps are level and tight.
4. Remove the fuse/fusible link box and con-
nect jumper cables in the sequence illus-
trated (
A,B,C,D).
CAUTION
●Always connect positive () to positive
() and negative () to body ground (for
example, strut mounting bolt, engine
lift bracket, etc.) — not to the battery.
● Make sure the jumper cables do not
touch moving parts in the engine com-
partment and that the cable clamps do
not contact any other metal. 5. Start the engine of the booster vehicle and
let it run for a few minutes.
6. Keep the engine speed of the booster ve- hicle at about 2,000 rpm, and start the en-
gine of the vehicle being jump started.
CAUTION
Do not keep the starter motor engaged for
more than 10 seconds. If the engine does
not start right away, turn the key off and
wait 3 to 4 seconds before trying again.
7. After starting the engine, carefully discon- nect the negative cable and then the positive
cable.

CAUTION
Be sure to remove any old gasket material
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 resistance 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 removal.
12. Turn the engine off and wait more than 10 minutes. Check the oil level. Add engine
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 after a shorter time interval than
if your vehicle was operating on pure
petroleum-based diesel. For additional in-
formation, refer to the “Maintenance” sec-
tion in the “Titan Owner’s Manual.”

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 and protective 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.
● Depending on the circumstance, diesel
fuel is flammable. When inspecting or
performing 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 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 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

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.
