stop start NISSAN TITAN 2016 2.G Repair Manual

The water/fuel separator should be drained when
indicated by illumination of the water in fuel warn-
ing light.
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.
ENGINE PROTECTION MODE
The diesel engine in this vehicle is equipped with
electronically controlled fuel and emission sys-
tems. Both systems monitor engine temperatures
and pressures, and then modify 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 extended peri-
ods of time, and the service engine soon light is
illuminated, have the system checked. It is recom-
mended 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 inter-
val beyond the recommended interval can nega-
tively affect engine performance, fuel economyand engine life. For additional information, refer to
the “Do-it-yourself” section of this manual.
GLOW PLUGS
The diesel engine glow plug system consists 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 energized varies depend-
ing on engine and environmental conditions. The
required time for the glow plugs to be energized
decreases as coolant temperature increases. For
additional information, refer to the “Starting and
stopping the engine” section of this manual.
DIESEL PARTICULATE FILTER
SYSTEM
Your vehicle is equipped with a diesel particulate
filter in the exhaust system. The diesel particulate
filter reduces carbon emissions by trapping ex-
haust particulates (soot) before they reach the
tailpipe. You must properly maintain your diesel
particulate filter in order for it to function properly.
Regeneration of the diesel particulate filter oc-
curs automatically during operation above 5 mph
(8 km/h) and requires no actions from the driver.
If you do a lot of idling or stop and go driving, pay attention to maintenance messages that alert you
when you need to drive to activate the automatic
regeneration process. For additional information,
refer to the ”Automatic Regeneration” in the “Do-
it-yourself” section of this manual.
SELECTIVE CATALYTIC REDUCTION
SYSTEM
Your vehicle is equipped with a selective catalytic
reduction system designed to reduce emission
levels of nitrogen oxides from the exhaust of your
diesel engine. This system relies on the use of
Diesel Exhaust Fluid (DEF) that you must replen-
ish at certain intervals. Failure to maintain proper
DEF levels or if the DEF becomes contaminated
will result in vehicle speed limitation to 5 mph. For
additional information, refer to the ”Meters and
gauges” and “Capacities and Specifications”
sections of this manual.

● Do not add gasoline, alcohol or kero-
sene to diesel fuel.
CAUTION
● Read all starting instructions carefully
prior to starting your vehicle.
● When starting the engine in extremely
cold temperatures, it is recommended
to allow the engine to idle for several
minutes before driving the vehicle.
● The use of the factory engine block
heater (if so equipped) will assist in
starting the engine in extreme cold am-
bient temperatures. For additional in-
formation, refer to “Starting and driv-
ing” section of your owner’s manual. Engine warming
This message may display during cold starting

3-2Starting and Stopping the Engine

3. Allow the engine to idle for at least 30 sec-onds after starting. Do not race the engine
while warming it up. Drive at moderate
speed for a short distance first, especially in
cold weather.
In cold weather, keep the engine running for
a minimum of 2–3 minutes before shutting it
off. Starting and stopping the engine over a
short period of time may make the vehicle
more difficult to start.
SWITCHING ENGINE OFF
Press the ignition to the off position.
To prolong the engine life (especially after ex-
tended high speed, high ambient temperature, or
during heavy load operation, such as trailering) , it
is recommended that a hot engine be idled for
3–5 minutes before shutting down. This allows
the turbocharged engine to cool down.
ENGINE BREAK-IN
RECOMMENDATIONS
● Warm up the engine before operating it un-
der load.
● Do not operate the engine at idle for ex-
tended periods.
● Prevent engine lugging by selecting the ap-
propriate transmission gear. ●
Monitor the vehicle oil pressure and tem-
perature gauges.
● Check fluid levels frequently (oil and cool-
ant) .
● Vary the throttle position at highway speeds
when carrying weight or towing.
NOTE:
Extended light or no load operation will
extend the time before the engine reaches
its full efficiency. If the engine is operated
in this manner reduced fuel economy and
power may be observed.
The aforementioned procedure should be ob-
served for the first 6,000 miles. The engine run-in
is improved by operating the vehicle under load.
REMOTE START (if so equipped)
CAUTION
Laws in some jurisdictions prohibit use of
remote start. Vehicles started with the remote start require the
ignition switch to be placed in the ON position
before the shift lever can be moved from the P
(Park) position. To place the ignition switch to the
ON position, follow these steps:
1. Make sure that the Intelligent Key is on you.
2. Apply the brake.
3. Press the ignition switch once to the ON position.
For additional information, refer to “NISSAN In-
telligent Key®” in the “Pre-driving checks and
adjustments” section of your owner’s manual.
ENGINE BLOCK HEATER (if so
equipped)
The power cable to operate the heater is avail-
able as a service part from an authorized NISSAN
dealer.
For additional information, refer to “Engine block
heater” in the “Starting and Driving” section of
your owner’s manual.

DIESEL FUEL-FILLER CAP
WARNING
●Diesel fuel is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seriously
injured if it is misused or mishandled.
Always stop the engine and do not
smoke or allow open flames or sparks
near the vehicle when refueling. ●
Do not attempt to top off the fuel tank
after the fuel pump nozzle shuts off
automatically. Continued refueling may
cause fuel overflow, resulting in fuel
spray and possibly a fire.
● Use only an original equipment type
fuel-filler cap as a replacement. It has a
built-in safety valve needed for proper
operation of the fuel system and emis-
sion control system. An incorrect cap
can result in a serious malfunction and
possible injury. It could also cause
the
Malfunction Indicator Light
(MIL) to come on.
● Do not use starting fluids with this en-
gine. It is equipped with an intake air
heater. The use of starting fluid could
cause an explosion, fire, personal in-
jury, system or engine damage.
● Do not fill a portable fuel container in
the vehicle or trailer. Static electricity
can cause an explosion of flammable
liquid, vapor or gas in any vehicle or
trailer. To reduce the risk of serious
injury or death when filling portable fuel
containers:
– Always place the container on the ground when filling. – Do not use electronic devices when
filling.
– Keep the pump nozzle in contact with the container while you are fill-
ing it.
– Use only approved portable fuel con- tainers for flammable liquid.
CAUTION
●For additional information, refer to the
“Malfunction Indicator Light (MIL)” in
the “Instruments and Controls” section
of the Titan Owner’s Manual.
● If fuel or Diesel Exhaust Fluid (DEF) is
spilled on the vehicle body, flush it away
with water to avoid paint damage

WARNING
●Stay clear from the exhaust outlet and
exhaust 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 com-
ponents may ignite them.
CAUTION
To maintain maximum Diesel Particulate
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 “Technical and con-
sumer information” 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 modify 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 muffler.
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, par-
ticulate matter accumulated in the DPF is auto-
matically burned and converted to harmless sub-
stances during driving. However, particulate
matter collected in the DPF cannot be burned
under the following conditions: ● When vehicle speed remains below 7 mph
(11 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 be-
fore it has warmed up. In these cases, it becomes difficult to burn par-
ticulate matter that has accumulated in the DPF.
As a result, the DPF warning light will
illuminate/blink and one of the following mes-
sages will display on the vehicle information dis-
play (in order of severity):
● Exhaust Filter Overloaded See Owners
Manual for Drive Pattern
● Exhaust Filter Overloaded Engine Power
Reduced See Owners Manual
● Exhaust Filter Overloaded Immediate Ser-
vice Required
For additional information, refer to the “Meters
and Gauges section of this manual.
CAUTION
●If the vehicle continues to be driven
with the DPF warning light illuminated
and without doing the regeneration
process, the fail-safe will limit the en-
gine revolutions and/or torque. In this
case, it is recommended to contact a
NISSAN dealer to have the Service Re-
generation procedure performed.
