2021 NISSAN TITAN manual transmission

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions which
should be closely observed.
WARNING
• Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. Move the shif t le-
ver to P (Park)
• Be sure the ignition switch is in the
OFF or LOCK position when perform-
ing any parts replacement or repairs.
• If you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans,
belts and any other moving parts.
• It is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
• Always wear eye protection when-
ever you work on your vehicle.
• The automatic engine cooling fan (if
so equipped) may come on at any
time without warning, even if the ignition switch is in the OFF position
and the engine is not running. To
avoid injury, always disconnect the
negative battery cable before work-
ing near the fan.
• If you must run the engine in an en-
closed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
• Never get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.
• Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
• Because the fuel lines are under high
pressure even when the engine is off,
it is recommended that you visit a
NISSAN dealer for service of the fuel
filter or fuel lines.
CAUTION
• Do not work under the hood while
the engine is hot. Turn the engine off
and wait until it cools down.
•
Avoid contact with used engine oil and
coolant. Improperly disposed engine oil, engine coolant and/or other ve-
hicle fluids can damage the environ-
ment. Always conform to local regula-
tions for disposal of vehicle fluid.
•
Never leave the engine or automatic
transmission related component
harnesses disconnected while the
ignition switch is in the ON position.
• Never connect or disconnect the bat-
tery or any transistorized compo-
nent while the ignition switch is in
the ON position.
NOTE:
If the battery is dead the transmission
will not manually shif t to other positions.
This “Do-it-yourself ” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine NISSAN service manual is also
available. For additional information, see
“Owner's Manual/Service Manual order in-
formation” (P. 10-60).
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect warranty coverage. If in doubt
about any servicing, it is recommended
that you have it done by a NISSAN dealer.
MAINTENANCE PRECAUTIONS
8-2Do-it-yourself

The engine cooling system is filled at the
factory with a pre-diluted mixture of 50%
Genuine NISSAN Long Life Antifreeze/
Coolant (blue) and 50% water to provide
year-round antifreeze and coolant protec-
tion. The antifreeze solution contains rust
and corrosion inhibitors. Additional engine
cooling system additives are not neces-
sary.
WARNING
• Never remove the radiator or coolant
reservoir cap when the engine is hot.
Wait until the engine and radiator
cool down. Serious burns could be
caused by high pressure fluid escap-
ing from the radiator. For additional
information on precautions, see “If
your vehicle overheats” (P. 6-12).
• The radiator and coolant reservoir
are equipped with a pressure type ra-
diator cap. To prevent engine dam-
age, it is recommended that you use
only a Genuine NISSAN radiator cap.
CAUTION
• Never use any cooling system addi-
tives such as radiator sealer. Addi-
tives may clog the cooling system
and cause damage to the engine,
transmission and/or cooling system.
• When adding or replacing coolant, it
is recommended that you use only
Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equiva-
lent. Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is pre-
diluted to provide antifreeze protec-
tion to -34° F (-37° C). If additional
freeze protection is needed due to
weather where you operate your ve-
hicle, add Genuine NISSAN Long Life
Antifreeze/Coolant (blue) concen-
trate following the directions on the
container. If an equivalent coolant
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is used, fol-
low the coolant manufacturer’s in-
structions to maintain minimum an-
tifreeze protection to -34° F (-37° C).
The use of other types of coolant so-
lutions other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue)
or equivalent may damage the en-
gine cooling system. •
The life expectancy of the factory-fill
coolant is 105,000 miles (168,000 km)
or 7 years. Mixing any other type of
coolant other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue)
(or equivalent coolant), including
Genuine NISSAN Long Life
Antifreeze/Coolant (green), or the
use of non-distilled water may re-
duce the life expectancy of the
factory-fill coolant. For additional in-
formation, see the "Maintenance and
schedules" section of this manual.

When checking or replacement is required,
it is recommended that you visit a NISSAN
dealer for this service.
CAUTION
• NISSAN recommends using Genuine
NISSAN Matic P ATF. Do not mix with
other fluids.
• Do not use CVT fluid or manual trans-
mission fluid in this transmission.
Damage caused by the use of fluids
other than as recommended is not
covered under NISSAN’s New Vehicle
Limited Warranty outlined in your
Warranty Information Booklet.
• Using fluids that are not equivalent
to Genuine NISSAN Matic P ATF may
also damage the transmission. Dam-
age caused by the use of fluids other
than as recommended is not covered
under NISSAN’s New Vehicle Limited
Warranty outlined in your Warranty
Information Booklet.
The specified automatic transmission fluid
is also described on caution labels located
in the engine compartment. Check the power steering fluid level when
the engine is stopped.
The fluid level should be between the COLD
MAX line and the COLD MIN line on the
power steering fluid reservoir at cold fluid
temperatures of 32° - 86°F (0° - 30°C) or at
the HOT MAX line on the power steering
fluid reservoir at hot fluid temperatures of
122° - 176°F (50° - 80°C).If the fluid is cold and is at or below the
COLD MIN line, add Genuine NISSAN PSF-II
or equivalent to the COLD MAX line. If the
fluid is hot and below the HOT MAX line, add
Genuine NISSAN PSF-II or equivalent to the
HOT MAX line. Remove the cap and fill
through the opening.
CAUTION
• DO NOT OVERFILL.
• Do not reuse power steering fluid.
• Recommended fluid is Genuine
NISSAN PSF-II or equivalent

CAUTION
• Do not ground accessories directly to
the battery terminal. Doing so will
bypass the variable voltage control
system and the vehicle battery may
not charge completely.
• Use electrical accessories with the
engine running to avoid discharging
the vehicle battery.
NOTE:
If the battery is dead the transmission
will not manually shif t into another
position.
Your vehicle is equipped with a variable
voltage control system. This system mea-
sures the amount of electrical discharge
from the battery and controls voltage gen-
erated by the generator.
The current sensor is located near the bat-
tery along the negative battery cable. If you
add electrical accessories to your vehicle,
be sure to ground them to a suitable body
ground such as the frame or engine block
area.

• Use the Tow Mode or downshif t thetransmission to a lower gear for engine
braking when driving down steep or long
hills. This will help slow the vehicle without
applying the brakes.
• Avoid holding the brake pedal down too long or too frequently. This could cause
the brakes to overheat, resulting in re-
duced braking efficiency.
• Increase your following distance to allow for greater stopping distances while tow-
ing a trailer. Anticipate stops and brake
gradually.
• NISSAN recommends that the cruise control (if so equipped) not be used while
towing a trailer.
• While towing a trailer, do not use the fol- lowing systems (if so equipped):–– the Lane Departure Warning (LDW) sys- tem
–– the Blind Spot Warning (BSW) system
– – the Intelligent Cruise Control (ICC) sys-
tem
– – the Automatic Emergency Braking
(AEB) system
– – the Intelligent Forward Collision Warn-
ing (I-FCW) system
– – the Rear Automatic Braking (RAB) sys-
tem –
– the Moving Object Detection (MOD)
system
– – the Cross Traffic Alert system
–– the Rear Sonar system
• Some states or provinces have specific regulations and speed limits for vehicles
that are towing trailers. Obey the local
speed limits.
• Check your hitch, trailer wiring harness connections, and trailer wheel lug nuts
af ter 50 miles (80 km) of travel and at
every break.
• When launching a boat, don't allow the water level to go over the exhaust tail
pipe or rear bumper.
• Make sure you disconnect the trailer lights before backing the trailer into the
water or the trailer lights may burn out.
When towing a trailer, final drive gear oil
should be replaced and transmission oil/
fluid should be changed more fre-
quently. For additional information, see
the “Do-it-yourself ” section of this
manual.Tow mode
Using tow mode is recommended when
pulling a heavy trailer or hauling a heavy
load. Press the TOW MODE switch to acti-
vate tow mode. The indicator light on the
TOW MODE switch illuminates when tow
mode is selected. Press the TOW MODE
switch again to turn tow mode off. Tow
mode is automatically canceled when the
ignition switch is turned off.
Tow mode includes the following features:
• Grade logic — Adjusts transmission shif ts when pulling a trailer or hauling a load up
a grade.
• Downhill Speed Control (DSC) — auto- matically downshif ts when driving down
a grade with a trailer or heavy load to help
control vehicle speed.
Driving the vehicle in the tow mode with no
trailer/load or light trailer/light load will not
cause any damage. However, fuel
economy may be reduced and the
transmission/engine driving characteris-
tics may feel unusual.
