2019 NISSAN FRONTIER PRO-4X engine

Four-Wheel Drive (4WD) models
with manual transmission
NISSAN recommends that towing dollies
be used when towing your vehicle or place
the vehicle on a flatbed truck as illustrated.
If you must use a pull behind tow truck put
the manual transmission in N (Neutral).
For 4WD vehicles, always tow with the
transfer case in the 2 HI position.
Your vehicle speed should never exceed
60 mph (97 km/h) when towing your ve-
hicle. Af ter towing 500 miles, start and idle
the engine with the transmission in N (Neu-tral) for two minutes. Failure to idle the en-
gine af ter every 500 miles of towing may
cause damage to the transmission’s inter-
nal parts.

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
protection. The antifreeze solution con-
tains rust and corrosion inhibitors. Addi-
tional engine cooling system additives are
not necessary.

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 insuffi-
cient 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 ex-
pectancy of the factory-fill coolant is
105,000 miles (168,000 km) or 7 years. Mixing
any other type of coolant or the use of
non-distilled water will reduce the life ex-
pectancy of the factory-fill coolant. For ad-
ditional information, refer to the "Mainte-
nance and schedules" section of this
manual.
If the cooling system frequently requires
coolant, it is recommended that you visit
a NISSAN dealer for this service.
For additional information on the location
of the engine coolant reservoir, refer to “En-
gine compartment 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 over-
heating.

CAUTION
Oil level should be checked regularly.
Operating the engine with an insuffi-
cient amount of oil can damage the en-
gine, and such damage is not covered
by warranty.
CHANGING ENGINE OIL AND OIL
FILTER
For additional information on engine oil
and oil filter change, refer to the instruc-
tions outlined in this section.
Vehicle set-up
1. Park the vehicle on a level surface andapply the parking brake.
2. Run the engine until it reaches operat- ing temperature.
3. Turn the engine off and wait for 15 min- utes.
4. Raise and support the vehicle using a suitable floor jack and safety jack
stands.
∙ Place the safety jack stands under the vehicle jack-up points.
∙ A suitable adapter should be attached to the jack stand saddle.

CAUTION
Be careful not to burn yourself, as the
engine oil is hot.

∙ Keep the battery surface clean and dry.Clean the battery with a solution of bak-
ing soda and water.
∙ Make certain the terminal connections are clean and securely tightened.
∙ If the vehicle is not to be used for 30 days or longer, disconnect the nega-
tive (-) battery terminal cable to prevent
discharge.
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.

CAUTION
∙ Do not ground accessories directly tothe battery terminal. Doing so will by-
pass the variable voltage control sys-
tem and the vehicle battery may not
charge completely.
∙ Use electrical accessories with the en- gine running to avoid discharging the
vehicle battery.
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
Ais 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.
