coolant level NISSAN TITAN 2019 Owner´s Manual

Add a washer solvent to the washer for
better cleaning. In the winter season, add a
windshield washer antifreeze. Follow the
manufacturer’s instructions for the mix-
ture ratio.
Refill the reservoir more frequently when
driving conditions require an increased
amount of windshield-washer fluid.
Recommended fluid is Genuine NISSAN
Windshield Washer Concentrate Cleaner &
Anti-freeze or equivalent.
CAUTION
∙ Do not substitute engine antifreezecoolant for windshield-washer fluid.
This may result in damage to the
paint.
∙ Do not fill the windshield-washer fluid reservoir with washer fluid concen-
trates at full strength. Some methyl
alcohol based washer fluid concen-
trates may permanently stain the
grille if spilled while filling the
windshield-washer fluid reservoir. ∙ Pre-mix washer fluid concentrates
with water to the manufacturer’s rec-
ommended levels before pouring the
fluid into the windshield-washer fluid
reservoir. Do not use the windshield-
washer fluid reservoir to mix the
washer fluid concentrate and water.

Seats:Check seat position controls such
as seat adjusters, seatback recliner, etc., to
ensure they operate smoothly and all
latches lock securely in every position.
Check that the head restraints/headrests
move up and down smoothly and the locks
(if so equipped) hold securely in all latched
positions.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, anchors,
adjusters and retractors) operate properly
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage.
Steering wheel: Check for changes in the
steering system, such as excessive free-
play, hard steering or strange noises.
Warning lights and chimes: Make sure all
warning lights and chimes are operating
properly.
Windshield wiper and washer*: Check
that the wipers and washer operate prop-
erly and that the wipers do not streak.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel).
Battery* (for serviceable batteries):
Check the fluid level in each cell. The fluid
should be at the bottom of the filler open-
ing. Vehicles operated in high tempera-
tures or under severe conditions require
frequent checks of the battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of elec-
tronic accessories that consume bat-
tery power when the engine is not
running (Phone chargers, GPS, DVD
players, etc.).
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health. Brake fluid level*:
Make sure that the brake
fluid level is between the MIN and MAX lines
on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure the drive
belts are not frayed, worn, cracked or oily.
Engine oil level*: Check the level af ter
parking the vehicle on a level surface with
the engine off. Wait more than 10 minutes
for the oil to drain back into the oil pan.
Exhaust system: Visually inspect the ex-
haust pipes, muffler and hangers for leaks,
cracks, deterioration and damage. Tighten
connections or replace parts as necessary.
For additional information, refer to “Exhaust
gas (carbon monoxide)” in the “Starting and
driving” section of this manual.
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks af ter the
vehicle has been parked for a while. Water
dripping from the air conditioner af ter use
is normal. If you should notice any leaks or if
fuel fumes are evident, check for the cause
and have it corrected immediately.
9-4Maintenance and schedules

Power steering fluid level* and lines:
Check the level when the fluid is cold, with
the engine off. Check the lines for proper
attachment, leaks, cracks, etc.
Radiator and hosesCheck the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, defor-
mation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances from the underbody, otherwise
rust may form on the floor pan, frame, fuel
lines and exhaust system. At the end of
winter, the underbody should be thor-
oughly flushed with plain water, in those
areas where mud and dirt may have accu-
mulated. For additional information, refer
to the “Appearance and care” section of this
manual.
Windshield-washer fluid*: Check that
there is adequate fluid in the reservoir. The following descriptions are provided to
give you a better understanding of the
scheduled maintenance items that should
be regularly checked or replaced. The
maintenance schedule indicates at which
mileage/time intervals each item requires
service.
Items marked with
“*”are recommended
by NISSAN for reliable vehicle operation.
You are not required to perform mainte-
nance on these items in order to maintain
the warranties which come with your
NISSAN. Other maintenance items and in-
tervals are required.
When applicable, additional information
can be found in the “Do-it-yourself ” section
of this manual.
NOTE: NISSAN does not advocate the use
of non-OEM approved af termarket flush-ing systems and strongly advises againstperforming these services on a NISSANproduct. Many of the af termarket flushingsystems use non-OEM approved chemi-cals or solvents, the use of which has notbeen validated by NISSAN.
For recommended fuel, lubricants, fluids,
grease, and refrigerant, refer to “Recom-
mended fluids/lubricants and capacities” in the “Technical and consumer informa-
tion” section of this manual.
EMISSION CONTROL SYSTEM
MAINTENANCE:
Drive Belts*:
Check engine drive belts for

tension. Replace any damaged drive belts.
Engine Air Filter: Replace at specified in-
tervals. When driving for prolonged periods
in dusty conditions, check/replace the filter
more frequently.
Engine Coolant*: Replace coolant at the
specified interval. When adding or replac-
ing coolant, be sure to use only Genuine
NISSAN Long Life Antifreeze/Coolant (blue)
or equivalent with the proper mixture. (For
additional information on the proper mix-
ture for your area, refer to Engine cooling
system” in the “Do-it-yourself ” section of

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.

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.

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.
