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.
CHECKING ENGINE OIL LEVEL
NOTE:
The factory fill oil may include a red dye
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 ap-
proximately 4–5 oil changes.1. Park the vehicle on a level surface and
apply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature.
3. Turn off the engine. Wait more than
10 minutes for the oil to drain back
into the oil pan.
4. Remove the dipstick and wipe it clean. Reinsert it all the way.

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.

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.

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
