Preventive maintenance is the easiest and least
expensive type of maintenance. Keep records of
regularly scheduled maintenance and follow the
maintenance schedule recommendations out-
lined in the “Titan Owner’s Manual”.
Use the correct fuel, lubricating oil, and coolant in
your engine. Blending engine oil with fuel is pro-
hibited for engines with an aftertreatment system.
For additional information refer to the “Capacities
and Specifications” section in this manual.
A NISSAN dealership knows your vehicle. When
you require any service or have any questions,

DIESEL ENGINE OPERATION
The operation of the diesel engine in your new
vehicle varies from the operation of traditional
gasoline engines found in other vehicles. Read-
ing this supplement will familiarize you and other
operators of the vehicle with the unique mainte-
nance and operating procedures that will prolong
the life of the diesel engine and related systems.
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 & Coolant)
● 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.
DIESEL FUEL SYSTEM
The diesel engine fuel system is a pressurized
two-stage filtration system and consists of: ● A frame-mounted primary (stage 1) fuel filter
containing water/fuel separator, electric fuel
pump, and water in fuel drain valve
● An engine-mounted secondary (stage 2)
fuel filter
● A fuel injector for each cylinder (8 total)
● A high-pressure fuel pump
● A high-pressure fuel rail for each cylinder
bank (2 total)
● High-pressure fuel lines from the high-
pressure fuel pump to the right bank fuel rail,
right bank fuel rail to the left bank fuel rail,
and fuel rails to fuel injectors.
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 recommended service interval or
when indicated by the information display. For
additional information, refer to the “Titan Owner’s
Manual”.

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
Press 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.

● Prevent engine lugging by selecting the ap-

● Check fluid levels frequently (oil and cool-
ant) .
● Vary the throttle position at highway speeds

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.
