NISSAN FRONTIER 2021 Owners Manual

WAXING
Regular waxing protects the paint surface
and helps retain new vehicle appearance.
Polishing is recommended to remove
built-up wax residue and to avoid a weath-
ered appearance before re-applying wax.
A NISSAN dealer can assist you in choosing
the proper product.
• Wax your vehicle only af ter a thoroughwashing. Follow the instructions supplied
with the wax.
• Do not use a wax containing any abra- sives, cutting compounds or cleaners
that may damage the vehicle finish.
Machine compounding or aggressive pol-
ishing on a base coat/clear coat paint fin-
ish may dull the finish or leave swirl marks.
REMOVING SPOTS
Remove tar and oil spots, industrial dust,
insects, and tree sap as quickly as possible
from the surface of the paint to avoid last-
ing damage or staining. Special cleaning
products are available at a NISSAN dealer
or any automotive accessory store. It is
recommended that you visit a NISSAN
dealer for these products.
UNDERBODY
In areas where road salt is used in winter, it
is necessary to clean the underbody regu-
larly in order to prevent dirt and salt from
building up and causing the acceleration of
corrosion on the underbody and suspen-
sion. Before the winter period and again in
the spring, the underseal must be checked
and, if necessary, re-treated.
GLASS
Use glass cleaner to remove smoke and
dust film from the glass surfaces. It is nor-
mal for glass to become coated with a film
af ter the vehicle is parked in the hot sun.
Glass cleaner and a sof t cloth will easily
remove this film.

TIRE DRESSINGS
NISSAN does not recommend the use of
tire dressings. Tire manufacturers apply a
coating to the tires to help reduce discolor-
ation of the rubber. If a tire dressing is ap-
plied to the tires, it may react with the coat-
ing and form a compound. This compound
may come off the tire while driving and
stain the vehicle paint.
If you choose to use a tire dressing, take the
following precautions:
• Use a water-based tire dressing. Thecoating on the tire dissolves more easily
than with an oil-based tire dressing.
• Apply a light coat of tire dressing to help prevent it from entering the tire tread/
grooves (where it would be difficult to re-
move).
• Wipe off excess tire dressing using a dry towel. Make sure the tire dressing is com-
pletely removed from the tire tread/
grooves.
• Allow the tire dressing to dry as recom- mended by the tire dressing manufac-
turer. Occasionally remove loose dust from the
interior trim, plastic parts and seats using a
vacuum cleaner or sof t bristled brush. Wipe
the vinyl and leather (if so equipped) sur-
faces with a clean, sof t cloth dampened in
mild soap solution, then wipe clean with a
dry, sof t cloth.
Regular care and cleaning is required in
order to maintain the appearance of the
leather (if so equipped).
Before using any fabric protector, read the
manufacturer's recommendations. Some
fabric protectors contain chemicals that
may stain or bleach the seat material.
Use a cloth dampened only with water to
clean the meter and gauge lens.
CAUTION
• Never use benzine, thinner or any
similar material.
• Small dirt particles can be abrasive
and damaging to leather surfaces
and should be removed promptly. Do
not use saddle soap, car waxes, pol-
ishes, oils, cleaning fluids, solvents,
detergents or ammonia-based
cleaners as they may damage the
leather's natural finish.
• Never use fabric protectors unless
recommended by the manufacturer.
• Do not use glass or plastic cleaner on
meter or gauge lens covers. It may
damage the lens cover.
AIR FRESHENERS
Most air fresheners use a solvent that
could affect the vehicle interior. If you use
an air freshener, take the following precau-
tions:
• Hanging-type air fresheners can cause permanent discoloration when they con-
tact vehicle interior surfaces. Place the air
freshener in a location that allows it to
hang free and not contact an interior sur-
face.
CLEANING INTERIOR
7-4Appearance and care

• Liquid-type air fresheners typically clip onthe vents. These products can cause im-
mediate damage and discoloration
when spilled on interior surfaces.
Carefully read and follow the manufactur-
er's instructions before using the air fresh-
eners.
POWER MOONROOF (if so
equipped)
The sunshade is made from a tricot mate-
rial.

•Properly position the mats in the
floorwell using the floor mat posi-
tioning hook. For additional informa-
tion, refer to "Floor mat installation"
in this section.
• Make sure the floor mat does not in-
terfere with pedal operation.
• Periodically check the floor mats to
make sure they are properly
installed.
• Af ter cleaning the vehicle interior,
check the floor mats to make sure
they are properly installed.
The use of Genuine NISSAN floor mats can
extend the life of your vehicle carpet and
make it easier to clean the interior. Mats
should be maintained with regular clean-
ing and replaced if they become exces-
sively worn.
Floor mat installation
Your vehicle is equipped with floor mat po-
sitioning hook(s). The number and shape of
the floor mat positioning hooks for each
seating position varies depending on the
vehicle. When installing Genuine NISSAN floor mats,
follow the installation instructions provided
with the mat and the following:
1. With the ignition in the OFF position, the
shif t lever in P (Park) position and with
the parking brake fully applied, position
the floor mat in the floorwell so that the
floor mat grommet holes are aligned
with the hook(s).
2. Secure the grommet holes into the hook(s) and ensure that the floor mat is
properly positioned.
3. Make sure the floor mat does not inter- fere with pedal operation. With the igni-
tion still in the OFF position, the shif t le-
ver in the P (Park) position and with the
parking brake applied, fully apply and re-
lease all pedals. The floor mat must not
interfere with pedal operation or prevent
the pedal from returning to its normal
position.
It is recommended that you visit a NISSAN
dealer for details about installing the floor
mats in your vehicle. The illustration shows the location of the
floor mat positioning hooks.
SEAT BELTS
The seat belts can be cleaned by wiping
them with a sponge dampened in a mild
soap solution. Allow the belts to dry com-
pletely in the shade before using them. For
additional information, refer to “Seat belt
maintenance” in the “Safety—Seats, seat
belts and supplemental restraint system”
section of this manual.

WARNING
Do not allow wet seat belts to roll up in
the retractor. NEVER use bleach, dye or
chemical solvents to clean the seat
belts, since these materials may se-
verely weaken the seat belt webbing.MOST COMMON FACTORS
CONTRIBUTING TO VEHICLE
CORROSION
Most vehicle corrosion is caused by:
• The accumulation of moisture-retaining dirt and debris in body panel sections,
cavities, and other areas.
• Damage to paint and other protective coatings caused by gravel and stone
chips or minor traffic collisions.
ENVIRONMENTAL FACTORS
INFLUENCE THE RATE OF
CORROSION
Moisture
Accumulation of sand, dirt and water on
the vehicle body underside can accelerate
corrosion. Wet floor coverings will not dry
completely inside the vehicle and should
be removed for drying to avoid floor panel
corrosion.
Relative humidity
Corrosion will be accelerated in areas of
high relative humidity, especially those ar-
eas where the temperatures stay above
freezing and where atmospheric pollution
exists and road salt is used.
Temperature
High temperatures accelerate the rate of
corrosion to those parts which are not well
ventilated.
Air pollution
Industrial pollution, the presence of salt in
the air in coastal areas, or heavy road salt
use accelerates the corrosion process.
Road salt also accelerates the disintegra-
tion of paint surfaces.
PROTECT YOUR VEHICLE FROM
CORROSION
• Wash and wax your vehicle of ten to keepthe vehicle clean.
• Always check for minor damage to the paint and repair it as soon as possible.
• Keep drain holes at the bottom of the doors open to avoid water accumulation.
• Check the underbody for accumulation of sand, dirt or salt. If present, wash with
water as soon as possible.
CORROSION PROTECTION
Appearance and care7-7

CAUTION
• NEVER remove dirt, sand or other de-
bris from the passenger compart-
ment by washing it out with a hose.
Remove dirt with a vacuum cleaner
or broom.
• Never allow water or other liquids to
come in contact with electronic com-
ponents inside the vehicle as this
may damage them.
Chemicals used for road surface de-icing
are extremely corrosive. They accelerate
corrosion and deterioration of underbody
components such as the exhaust system,
fuel and brake lines, brake cables, floor pan
and fenders.
In winter, the underbody must be
cleaned periodically.
For additional protection against rust and
corrosion, which may be required in some
areas, it is recommended that you consult
a NISSAN dealer.
7-8Appearance and care

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.

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
