5. Remove the dipstick again and checkthe oil level. It should be between the
high and low marks
B. This is the nor-
mal operating oil level range. If the oil
level is below the low mark
A, remove
the oil filler cap and pour recom-
mended oil through the opening. Do
not overfill
C.
6. Recheck oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the sever-
ity of operating conditions.
CAUTION
Oil level should be checked regularly.
Operating the engine with an insuffi-
cient amount of oil can damage the en-
gine, and such damage is not covered
by warranty.

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.

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.

The dry paper type filter element may be
cleaned and reused. Replace it according
to the maintenance 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 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.

ENGINE OIL AND OIL FILTER
RECOMMENDATIONS
Selecting the correct oil
NOTE:
The factory fill oil may include a red dye
that that is added for manufacturing
quality processes. The dye makes the oil
appear to be red. This is normal. The red
dye will be flushed from the engine af ter
approximately 4-5 oil changes.It is essential to choose the correct grade,
quality and viscosity engine oil to ensure
satisfactory engine life and performance.
For additional information, refer to “Recom-
mended fluids/lubricants and capacities”
in this section. NISSAN recommends the
use of an energy conserving oil in order to
improve fuel economy.Select only engine oils that meet the Cum-
mins® Engineering Standard (CES) classifi-
cation (CES 20081) and American Petro-
leum Institute (API) certification (API CJ-4,
Low Ash Oil) and SAE viscosity standard
(10W-30 or 5W-40). These oils have the API
certification mark and CES 20081 on the
container. Oils which do not have the
specified information on the label should
not be used as they could cause engine
damage.
Oil additives
NISSAN does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used
and maintenance intervals are followed.
Oil which may contain foreign matter or
has been previously used should not be
used.LTI2207
Capacities and Specifications8-5

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.

WARNING
A vehicle equipped with Four-Wheel
Drive (4WD) should never be tested us-
ing a two wheel dynamometer (such as
the dynamometers used by some
states for emissions testing), or similar
equipment. Make sure you inform the
test facility personnel that your vehicle
is equipped with 4WD before it is placed
on a dynamometer. Using the wrong
test equipment may result in transmis-
sion damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.
Due to legal requirements in some states
and Canadian Provinces, your vehicle may
be required to be in what is called the
“ready condition” for an
Inspection/Maintenance (I/M) test of the
emission control system.
If a powertrain system component is re-
paired or the battery is disconnected, the
vehicle may be reset to a “not ready” condi-
tion.
The vehicle is set to the “ready condition”
when it is driven through certain driving
patterns. Usually, the ready condition can
be obtained by ordinary usage of the ve-
hicle.
