transmission NISSAN FRONTIER 2021 Owner's Manual

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.
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 the trans-
mission related component harness
connector disconnected while the ig-
nition 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.
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, refer
to “Owner's Manual/Service Manual order
information” in the “Technical and con-
sumer information” section of this manual.
NISSAN recommends the use of Genuine
NISSAN parts or equivalent. The use of parts
that do not meet or exceed NISSAN specifica-
tions, can cause damage to your vehicle, and
have an effect on your warranty coverage. It is
recommended that you visit a NISSAN dealer
parts department who can provide informa-
tion on the proper parts for your vehicle.
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.
NOTE:
If the battery is dead the transmission will
not manually shif t into other positions.
MAINTENANCE PRECAUTIONS

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.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, be
sure to use only Genuine NISSAN
Long Life Antifreeze/Coolant (blue)
or equivalent. 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, refer to the "Maintenance
and schedules" section of this
manual.

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 other
positions.
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
OAis located near the
battery along the negative battery cable. If
you add electrical accessories to your ve-
hicle, be sure to ground them to a suitable
body ground such as the frame or engine
block area.

NOTE:Maintenance items with “” should be performed more frequently according to the “Maintenance under severe driving conditions”.
(1) If operating mainly in dusty conditions, more frequent maintenance may be required.
(2) Request the dealer to inspect the fluid deterioration data using a CONSULT. If the deterioration data is more than 77000, replace the AT fluid.
(3) If using under severe conditions such as towing a trailer, using a car-top carrier, or driving on rough or muddy roads, change (not just inspect) oilat every
30,000 miles (48,000 km) or 24 months. NISSAN recommends using Genuine NISSAN Matic P automatic transmission fluid. Using automatic transmission
fluid that is not equivalent to Genuine NISSAN Matic P may damage the transmission or impact transmission durability. Damage caused by the use of fluid
other than as recommended is not covered under the NISSAN New Vehicle Limited Warranty.
(4) Af ter 60,000 miles (96,000 km) or 48 months, inspect every 15,000 miles (24,000 km) or 12 months. Replace the drive belts if found damaged.
(5) First replacement interval is 105,000 miles (168,000 km) or 84 months. Af ter first replacement, replace every 75,000 miles (120,000 km) or 60 mont hs.
(6) Use only Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent with proper mixture ratio of 50% antifreeze and 50% demineralized or di stilled
water. Mixing any other type of coolant or the use of non-distilled water may reduce the life expectancy of the factory fill coolant.
(7) Periodic maintenance is not required.
(8) Periodic maintenance is not required. However, if valve noise increased, inspect valve clearance.
(9) Replace spark plug when the plug gap exceeds 0.053 in (1.35 mm) even if within specified replacement mileage.
(10) For additional information on tire rotation, refer to “General maintenance” in the section.
(11) If towing a trailer, using a car-top carrier or driving on rough or muddy roads, change (not just inspect) oil at every 20,000 miles (32,000 km) or 24 months.
* Maintenance items and intervals with “*” are recommended by NISSAN for reliable vehicle operation. The owner need not perform such maintenance in
order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and intervals are required.
