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.

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.

For additional information, refer to “Diesel
Particulate Filter (DPF)” in the “Maintenance”
section of this manual.
CAUTION
If you continue driving with the DPF
warning light on without performing
the filter regeneration, this will lead to
particle matter overload in the filter. If
this happens, the Malfunction Indicator
Light (MIL) will turn on to indicate the
necessity that a NISSAN or qualified
dealer performs the service regenera-
tion. The performance of the engine
might be limited to protect the DPF
system.
Vehicle information display
The vehicle information display shows vari-
ous meters and gauges that pertain to the
