CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir
when the engine is cold. If the coolant
level is below the MIN level
B, add coolant
to the MAX level
A. If the reservoir is empty,
check the coolant level in the radiator
when the engine is cold. If there is insuffi-
cient coolant in the radiator, fill the radiator
with coolant up to the filler opening and
also add it to the reservoir up to the MAX
level
A.
This vehicle contains Genuine NISSAN Long
Life Antifreeze/Coolant (blue). The life ex- pectancy of the factory-fill coolant is
45,000 miles (78,000 km) or 3 years. Mixing
any other type of coolant or the use of
non-distilled water may reduce the life ex-
pectancy of the factory-fill coolant. For ad-
ditional information, refer to the Titan Own-
er’s Manual.
CAUTION
Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause
damage to the engine, transmission
and/or cooling system.
If the cooling system frequently requires
coolant, have it checked. It is recom-
mended that you visit a NISSAN dealer
for this service.
For additional information on the location
of the engine coolant reservoir, refer to “En-
gine compartment check locations” in this
section.
CHANGING ENGINE COOLANT
A NISSAN dealer can change the engine
coolant. The service procedure can be
found in the NISSAN Service Manual. Improper servicing can result in reduced
heater performance and engine over-
heating.
WARNING
∙ To avoid the danger of being scalded,
never change the coolant when the
engine is hot.
∙ Never remove the radiator or engine coolant reservoir cap when the en-
gine is hot. Serious burns could be
caused by high pressure fluid escap-
ing from the radiator.
∙ Avoid direct skin contact with used coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
∙ Keep coolant out of the reach of chil- dren and pets.
Engine coolant must be disposed of prop-
erly. Check your local regulations.

CAUTION
Be sure to remove any old gasket mate-
rial 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 resis- tance 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 re- moval.
12. Turn the engine off and wait more than 10 minutes. Check the oil level. Add en-
gine 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 af ter a shorter time in-
terval than if your vehicle was operat-
ing on pure petroleum-based diesel.
For additional information, refer to the
“Maintenance and schedules” section in
the Titan Owner’s Manual.
FUEL FILTER REPLACEMENT (stage
1 and 2)
A NISSAN dealer can change the stage 1
and stage 2 fuel filters. The service proce-
dure can be found in the NISSAN Service
Manual.
Improper servicing can result in the vehicle
not starting, fuel leaks and engine stalling.

WARNING
∙ Stay clear from the exhaust outlet andexhaust 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
components may ignite them.
CAUTION
To maintain maximum Diesel Particu-
late 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 “Capacities and
specifications” 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 modif y 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 muf-
fler. 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, particulate matter accu-
mulated in the DPF is automatically burned
and converted to harmless substances
during driving. However, particulate matter
collected in the DPF cannot be burned un-
der 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 before it has warmed up. In these cases, it becomes difficult to burn
particulate matter that has accumulated
in the DPF. As a result, the DPF warning light
will illuminate/blink and one of the follow-
ing messages will display on the vehicle
information display (in order of severity):
∙ Exhaust Filter Overloaded See Owner’s Manual for Drive Pattern
∙ Exhaust Filter Overloaded Engine Power Reduced See Owner’s Manual
∙ Exhaust Filter Overloaded Immediate Service Required
For additional information, refer to “Meters
and gauges" in the “Instrument panel” sec-
tion of this manual.
CAUTION
∙ If the vehicle continues to be driven with the DPF warning light illumi-
nated and without doing the regen-
eration process, the fail-safe will limit
the engine revolutions and/or torque.
In this case, it is recommended to con-
tact a NISSAN dealer to have the Ser-
vice Regeneration procedure
performed.

AUTOMATIC REGENERATION
Automatic regeneration occurs when the
control module detects the exhaust filter
needs to be cleaned. This is a normal pro-
cess and will not typically require any op-
erator interaction.
If the automatic regeneration is not able to
clean the exhaust filter the vehicle informa-
tion display will display the following mes-
sages in order of severity:∙ Exhaust Filter Overloaded See Owner’s Manual for Drive Pattern
∙ Exhaust Filter Overloaded Engine Power Reduced See Owner’s Manual
∙ Exhaust Filter Overloaded Immediate Service Required
The instructions for these messages in the
“Meters and gauges” section of this manual
will inform the driver to modif y their driving
pattern to enable the automatic regenera-
tion process.

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 housing and the cover with a damp
cloth. NOTE:
Af ter 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
others 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 aircleaner 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 re-
sult in engine damage.
IN-CABIN MICROFILTER
The in-cabin microfilter restricts the entry
of airborne dust and pollen particles and
reduces some objectionable outside
odors. The filter is located behind the glove
box. For additional information on change
intervals, refer to “Gasoline standard main-
tenance" or "Diesel standard mainte-
nance" in the "Maintenance and sched-
ules" section of the Titan Owner’s Manual.
If replacement is required, it is recom-
mended that you visit a NISSAN dealer for
this service.

Oil viscosity
The engine oil viscosity or thickness
changes with temperature. Because of
this, it is important to select the engine oil
viscosity based on the temperatures at
which the vehicle will be operated beforethe next oil change. Choosing an oil viscos-
ity other than that recommended could
cause serious engine damage.
Selecting the correct oil filter
Your new NISSAN vehicle is equipped with a
high-quality Genuine NISSAN oil filter. When
replacing, use a Genuine NISSAN oil filter or
its equivalent for the reason described in
“Change intervals.”
Change intervals
The oil and oil filter change intervals for
your engine are based on the use of the
specified quality oils and filters. Using en-
gine oil and filters that are not of the speci-
fied quality, or exceeding recommended oil
and filter change intervals could reduce
engine life. Damage to the engine caused
by improper maintenance or use of incor-
rect oil and filter quality and/or viscosity is
not covered by the NISSAN New Vehicle
Limited Warranty.
Your engine was filled with a high-quality
engine oil when it was built. You do not have
to change the oil before the first recom-
mended change interval. Oil and filter
change intervals depend upon how you
use your vehicle.
Operation under the following conditions
may require more frequent oil and filter
changes:
∙ repeated short distance driving at cold outside temperatures
∙ driving in dusty conditions
∙ extensive idling
∙ towing a trailer
∙ stop and go commuting
∙ you must also change your oil and filter when the “Engine Oil-Service Due Now”
message is displayed.
For additional information, refer to the Ti-
tan Owner’s Manual.
