check engine NISSAN TITAN 2016 2.G Manual PDF

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.

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.

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir when
the engine is cold. If the coolant level is below
the MIN level
B, add coolant to the MAX level
A. If the reservoir is empty, check the coolant
level in the radiator when the engine is cold. If
there is insufficient coolant in the radiator, fill the
radiator with coolant up to the filler opening and
also add it to the reservoir up to the MAX level
A. This vehicle contains Genuine NISSAN Long Life
Antifreeze/Coolant (blue) . The life expectancy of
the factory-fill coolant is 45,000 miles
(78,000 km) or 3 years. Mixing any other type of
coolant or the use of non-distilled water will re-
duce the life expectancy of the factory-fill coolant.
For additional information, refer to the “Titan
Owners’s Manual”.
If the cooling system frequently requires
coolant, have it checked. It is recom-
mended you visit a NISSAN dealer for this
service.
For additional information on the location of the
engine coolant reservoir, refer to “Engine com-
partment check locations” in this section.
CHANGING ENGINE COOLANT
A NISSAN dealer can change the engine coolant.
The service procedure can be found in the
NISSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING
●
To avoid the danger of being scalded,
never change the coolant when the en-
gine is hot.
● Never remove the radiator or engine
coolant reservoir cap when the engine
is hot. Serious burns could be caused by
high pressure fluid escaping from the
radiator.
● Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner as
soon as possible.
● Keep coolant out of the reach of chil-
dren and pets.
Engine coolant must be disposed of properly.
Check your local regulations.

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 after a shorter time interval than
if your vehicle was operating on pure
petroleum-based diesel. For additional in-
formation, refer to the “Maintenance” sec-
tion 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 pro-
cesses. The dye makes the oil appear to be
red. This is normal. The red dye will be
flushed from the engine after approxi-
mately 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. Re- insert it all the way.

5. Remove the dipstick again and check the oillevel. It should be between the high and low
marks
B. This is the normal operating oil
level range. If the oil level is below the low
mark
A, remove the oil filler cap and pour
recommended 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 severity
of operating conditions.
CAUTION
Oil level should be checked regularly. Op-
erating the engine with an insufficient
amount of oil can damage the engine, and
such damage is not covered by warranty.
