coolant temperature NISSAN TITAN 2019 Owner´s Manual

∙ While going downhill, the weight of thetrailer pushing on the tow vehicle may
decrease overall stability. Therefore, to
maintain adequate control, reduce your
speed and shif t to a lower gear. Avoid
long or repeated use of the brakes
when descending a hill, as this reduces
their effectiveness and could cause
overheating. Shif ting to a lower gear in-
stead provides “engine braking” and re-
duces the need to brake as frequently.
∙ If the engine coolant temperature rises to a high temperature, refer to “If your
vehicle overheats” in the “In case of
emergency” section of this owner’s
manual.
∙ Trailer towing requires more fuel than normal circumstances.
∙ Avoid towing a trailer for your vehicle’s first 500 miles (805 km).
∙ For the first 500 miles (805 km) that you do tow, do not drive over 50 mph
(80 km/h).
∙ Have your vehicle serviced more of ten than at intervals specified. For addi-
tional information, refer to “Mainte-
nance schedules” in the “Maintenance
and schedule” section of this manual. ∙ When making a turn, your trailer wheels
will be closer to the inside of the turn
than your vehicle wheels. To compen-
sate for this, make a larger than normal
turning radius during the turn.
∙ Crosswinds and rough roads will ad- versely affect vehicle/trailer handling,
possibly causing vehicle sway. When
being passed by larger vehicles, be pre-
pared for possible changes in cross-
winds that could affect vehicle han-
dling.
Trailer Sway Assist :
To minimize trailer sway, your vehicle may
apply braking to individual wheels based
on input from your vehicle sensors and ve-
hicle speed. Trailer sway control is a func-
tion of the Vehicle Dynamic Control (VDC)
system and is active when the VDC func-
tion is enabled.
CAUTION
If the VDC-OFF switch is on (meaning
VDC system OFF), the Trailer Sway As-
sist is also disabled When Trailer Sway Assist is in operation, the
VDC warning light blinks. When vehicle con-
trol is regained, VDC warning light will turn
OFF.
For additional information about the VDC
system, refer to “Vehicle Dynamic Control
(VDC) OFF switch” in the “Instruments and
controls” section and “Vehicle Dynamic
Control (VDC) system” in the “Starting and
driving” section of this manual.
If Trailer Sway Assist activates, do the fol-
lowing:
1. Take your foot off the accelerator pedal to allow the vehicle to coast and steer
as straight ahead as the road condi-
tions allow. This combination will help
stabilize the vehicle
CAUTION
Do not try to correct trailer sway by
steering or applying the brakes.
2. When the trailer sway stops, gently ap- ply the brakes and pull to the side of the
road in a safe area.
3. Try to rearrange the trailer load so it is balanced. For additional information,
refer to “Pre-towing tips” in this section.

Preventive maintenance is the easiest and
least expensive type of maintenance. Keep
records of regularly scheduled mainte-
nance and follow the maintenance sched-
ule recommendations outlined in the Titan
Owner’s Manual.
Use the correct fuel, lubricating oil, and
coolant in your engine. Blending engine oil
with fuel is prohibited for engines with an
af tertreatment system. For additional in-
formation, refer to the “Capacities and
specifications” section of this manual.
A NISSAN dealership knows your vehicle.
When you require any service or have any
questions, they will be glad to assist you
with the extensive resources available to
them.
DIESEL ENGINE OPERATION
The operation of the diesel engine in your
new vehicle varies from the operation of
traditional gasoline engines found in other
vehicles. Reading this supplement will fa-
miliarize you and other operators of the
vehicle with the unique maintenance and
operating procedures that will prolong the
life of the diesel engine and related sys-
tems.
ENGINE BREAK-IN
RECOMMENDATIONS
∙ Warm up the engine before operating itunder load
∙ Do not operate the engine at idle for extended periods
∙ Prevent engine lugging by selecting the appropriate transmission gear
∙ Monitor the vehicle oil pressure and temperature gauges
∙ Check fluid levels frequently (Oil & 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
observed for the first 6,000 miles. The en-
gine run-in is improved by operating the
vehicle under load.
DIESEL FUEL SYSTEM
The diesel engine fuel system is a pressur-
ized two-stage filtration system and con-
sists of: ∙ A frame-mounted primary (stage 1) fuel filter containing water/fuel separator,
electric fuel pump, and water in fuel
drain valve
∙ An engine-mounted secondary (stage 2) fuel filter
∙ A fuel injector for each cylinder (8 total)
∙ A high-pressure fuel pump
∙ A high-pressure fuel rail for each cylin- der bank (2 total)
∙ High-pressure fuel lines from the high- pressure fuel pump to the right bank
fuel rail, right bank fuel rail to the lef t
bank fuel rail, and fuel rails to fuel injec-
tors.
GENERAL INFORMATION
1-2Introduction

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.
Introduction1-3

Low Diesel Exhaust Fluid (DEF)
warning light
When this warning light illuminates, the
DEF fluid needs to be topped off.
For additional information, refer to the “Fuel
and refueling” section of this manual.
Diesel Particulate Filter (DPF)
warning light
When the warning light illuminates, it indi-
cates that particulate matter is accumu-
lated to the specified amount of the limit in
the filter and the filter needs to regenerate.
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
diesel engine. The information that can be
found within the vehicle information dis-
play is as follows:
Exhaust temperature gauge
The exhaust temperature gauge is part of
the Auxiliary Gauges in the vehicle informa-
tion display.
Turbo meter
The turbo meter shows the amount of en-
gine boost.Diesel Exhaust Fluid (DEF) LEVEL
This gauge indicates the level of DEF in the
diesel system.
The DEF LEVEL information screen can be
turned on or off in the vehicle information
display. For additional information, refer to
“How to use the vehicle information dis-
play” in the “Vehicle information display”
section of the Titan Owner’s Manual.
Water in Fuel warning light
If this light illuminates, pull off of the road in
a safe area, stop the engine and immedi-
ately drain the water from the fuel sedi-
ment filter. For additional information, refer
to “Draining water” in the “Do-it-yourself ”
section of this manual.
Malfunction warning light (red)
If the warning light illuminates this indi-
cates either coolant temperature is above
a critical threshold or the exhaust tem-
peratures are above a critical threshold.
When illuminated this lamp indicates the
need to stop the engine as soon as it can
be safely done. The engine must remain
shut down until the engine can be repaired.

will be reduced. It is recommended that
you visit a NISSAN dealer or qualified tech-
nician immediately. For additional informa-
tion, refer to “Diesel Particulate Filter (DPF)”
in the “Do-it-yourself ” section of this
manual.
Engine Warming Keep Foot on Brake
This message appears during cold start
conditions when:∙ Brake pedal is depressed
∙ Push-button start button has been pressed
∙ Coolant temperature is below thresh- old
Keep foot on the brake until the engine
starts, which can take up to approximately
4 seconds. For additional information, refer
to “Starting the diesel engine” in the “Start-
ing and stopping the engine” section of this
manual. Engine Shutdown: Stop Safely
This message appears 30 seconds before
the vehicle is shutdown due to an above
normal operating exhaust temperature.
The Malfunction Indicator Light (MIL) and
malfunction warning light (red) will illumi-
nate. It is recommended that you visit a
NISSAN dealer or other qualified technician
immediately.
Engine Power Reduced
This message appears when the engine is
not operating under normal conditions. For
additional information, refer to “Engine Pro-
tection Mode” in the “Introduction” section
of this manual.
Service Air Filter
This warning appears when the air filter
needs to be serviced. For additional infor-
mation, refer to “Air cleaner” in the ”Mainte-
nance” section of the Titan Diesel Owner’s
Manual.Engine Oil Service due XX
This message is a count down of mileage
until the next engine oil service is due. Mile-
age until next required engine oil service
will be displayed by the vehicle information
display and will decrease at a higher rate as
vehicle operation severity (high duty cycle)
increases.
Coolant Level Low: See Owner’s Manual
This warning appears when the coolant
level in the reservoir is below the MIN level.
For additional information, refer to “Engine
Cooling System” in this manual.
Low Fuel Pressure: See Owner’s Manual
This message appears when low fuel pres-
sure has been detected downstream of
the stage 2 fuel filter. This message can
indicate the fuel filters are restricted and
require replacement. It is recommended
that you have the system checked by a
NISSAN dealer or other qualified technician.
Instrument Panel2-7

CAUTION
If the engine does not start, place the
ignition switch in the OFF position and
wait 10 seconds before cranking again,
otherwise the starter could be
damaged.3. Allow the engine to idle for at least 30 seconds af ter starting. Do not race
the engine while warming it up. Drive at
a moderate speed for a short distance
first, especially in cold weather.
In cold weather, keep the engine run-
ning for a minimum of 2–3 minutes
before shutting it off. Starting and
stopping the engine over a short pe-
riod of time may make the vehicle
more difficult to start.
SWITCHING ENGINE OFF
Push the ignition switch to the OFF posi-
tion.
To prolong the engine life (especially af ter
extended high speed, high ambient tem-
perature, or during heavy load operation,
such as trailering), it is recommended that
a hot engine be idled for 3–5 minutes be-
fore shutting down. This allows the turbo-
charged engine to cool down.
ENGINE BREAK-IN
RECOMMENDATIONS
∙ Warm up the engine before operating it under load.
∙ Do not operate the engine at idle for extended periods.
∙ Prevent engine lugging by selecting the appropriate transmission gear.
∙ Monitor the vehicle oil pressure and temperature gauges.
∙ Check fluid levels frequently (oil and coolant).
∙ Vary the throttle position at highway speeds when carrying weight or tow-
ing.
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
observed for the first 6,000 miles. The en-
gine run-in is improved by operating the
vehicle under load.
REMOTE ENGINE START (if so
equipped)
CAUTION
Laws in some jurisdictions prohibit use
of Remote Engine Start.
Vehicles started with the Remote Engine
Start require the ignition switch to be
placed in the ON position before the shif t
lever can be moved from the P (Park) posi-
tion. To place the ignition switch in the ON
position, follow these steps: 1. Make sure that the Intelligent Key is on you.
2. Apply the brake.
3. Push the ignition switch once to the ON position.
For additional information, refer to “NISSAN
Intelligent Key®” in the “Pre-driving checks
and adjustments” section of the Titan
