IMPORTANT INFORMATION ABOUT
THIS MANUAL
You will see various symbols in this manual.
They are used in the following ways:
WARNING
This is used to indicate the presence of
a hazard that could cause death or seri-
ous personal injury. To avoid or reduce
the risk, the procedures must be fol-
lowed precisely.
CAUTION
This is used to indicate the presence of
a hazard that could cause minor or
moderate personal injury or damage to
your vehicle. To avoid or reduce the risk,
the procedures must be followed
carefully.
FOREWORD
WHEN READING THIS SUPPLEMENT

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 recom-
mended service interval or when indicated
by the information display. For additional
information, refer to “Maintenance and
schedules” and “Instruments and controls”
sections of the Titan Owner’s Manual.
The water/fuel separator should be
drained when indicated by illumination of
the water in fuel warning light.
NOTE:
Proper fuel filter maintenance and
prompt water draining when the water
in the fuel filter warning light illuminates
is essential to prevent damage to fuel
injection system components. Ignoring
the water in fuel warning light can cause
your vehicle to go into a reduced power
mode and has the potential for fuel sys-
tem damage.ENGINE PROTECTION MODE
The diesel engine in this vehicle is equipped
with electronically controlled fuel and
emission systems. Both systems monitor
engine temperatures and pressures, and
then modif y engine operation accordingly.
It is normal for the diesel engine to operate
under these modified conditions for short
durations of time. If the engine operates
under the modified conditions for ex-
tended periods of time, and the service en-
gine soon light is illuminated, have the sys-
tem checked. It is recommended that you
visit a NISSAN dealer for this service as
soon as possible.
LUBRICATION SYSTEM
It is important to change the engine oil at
the recommended service intervals to
maintain oil viscosity. Extending the oil and
filter change interval beyond the recom-
mended interval can negatively affect en-
gine performance, fuel economy and en-
gine life. For additional information, refer to
the “Do-it-yourself ” section of this manual.
GLOW PLUGS
The diesel engine glow plug system con-
sists of:∙ Eight Glow Plugs (one per cylinder)
∙ Glow Plug Control Module - Uses input from the Engine Coolant Temperature
Sensor
The glow plugs are energized momentarily
when the ignition is first turned on. The
length of time that the glow plugs are en-
ergized varies depending on engine and
environmental conditions. The required
time for the glow plugs to be energized
decreases as coolant temperature in-
creases. For additional information, refer to
the “Starting and stopping the engine” sec-
tion of this manual.

DIESEL EXHAUST FLUID (DEF) FILL
CAP
CAUTION
∙ Overfilling your DEF tank can causedamage to the tank. ∙ DEF will freeze below 12°F (-11°C); how-
ever, your vehicle is equipped with an
automatic preheating system, which
allows the DEF system to operate be-
low 12°F (-11°C). When the vehicle is not
in operation for an extended period of
time with temperatures at or below
12°F (-11°C), the DEF tank could freeze.
In this condition, adding DEF will not
change the gauge level and added
DEF will not reach the pump, because
it will sit on top of the frozen layer. Move the vehicle to a warm location to
thaw the DEF completely for the
gauge to read accurately and allow
new DEF to reach the pump. If the tank
is overfilled and freezes, it could be
damaged, therefore do not overfill in
sustained cold conditions below 12°F
(-11°C).
∙ Do not put DEF into the fuel tank. This can cause engine damage that is not
covered by your vehicle’s warranty.
∙ Immediately wipe away any DEF that has spilled on painted surfaces with
water and a damp cloth to prevent
damage to the paint.

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.

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, then
turn it off.
3. Remove the oil filler cap
Aby turning it
counterclockwise.
4. Place a large drain pan under the drain plug
B.
5. Remove the drain plug
Bwith a
wrench by turning it counterclockwise
and completely drain the oil.
Remove and replace the engine oil fil-
ter at this time. For additional informa-
tion, refer to “Changing engine oil filter”
in this section.
∙ Waste oil must be disposed of prop-
erly.
∙ Check your local regulations.
WARNING
∙ Prolonged and repeated contact with
used engine oil may cause skin
cancer.
∙ Try to avoid direct skin contact with used oil. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
∙ Keep used engine oil out of reach of children.
CAUTION
Be careful not to burn yourself. The en-
gine oil may be hot.
6. Clean and reinstall the drain plug. Se- curely tighten the drain plug with a
wrench. Do not use excessive force.
Drain plug tightening torque: 25 f t-lb (34 N·m) 7. Refill engine with recommended oil
through the oil filler opening, then install
the oil filler cap securely.
For additional information on drain
and refill capacity, refer to “Recom-
mended fluids/lubricants and capaci-
ties” in the “Capacities and specifica-
tions” section of this manual.
The drain and refill capacity depends
on the oil temperature and drain time.
Use these specifications for reference
only. Always use the dipstick to deter-
mine when the proper amount of oil is
in the engine.
8. Start the engine. Check for leakage around the drain plug and oil filter. Cor-
rect as required.
9. Turn the engine off and wait more than 10 minutes. Check the oil level with the
dipstick. Add engine oil if necessary.
NOTE:
For additional information on resetting
the oil control system, refer to “Resetting
the oil control system” in the “Instrument
panel” section of this manual.

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.
