fuel NISSAN FRONTIER 2023 Owner's Guide

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.
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. •
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.
• On gasoline engine models, the fuel
filter or fuel lines should be serviced
because the fuel lines are under high
pressure even when the engine is off.
It is recommended that you visit a
NISSAN dealer for this service.
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 vehicle fluids can damage the
environment. Always conform to lo-
cal regulations 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.
NOTE:
If the battery is completely drained the
transmission will not manually shif t to
other positions.
MAINTENANCE PRECAUTIONS
8-2Do-it-yourself

If replacement is required, it is recom-
mended that you visit a NISSAN dealer for
this service.The dry paper type filter element may be
cleaned and reused. Replace it according
to the maintenance log shown in the
"Maintenance and schedules" section of
this manual.
To remove the air cleaner filter:
1. Unlatch the clips
OAand move the air
cleaner cover upward.
2. Remove the air cleaner filter.
3. Wipe the inside of the air cleaner filter housing and the cover with a damp
cloth.
NOTE:
Af ter installing a new air cleaner filter,
make sure the air cleaner cover is seated
in the housing and latch the clips
OA.
WARNING
• Operating the engine with the air
cleaner removed can cause you or
others to be burned. The air cleaner
not only cleans the air, it stops the
flame if the engine backfires. If it isn't
there, and the engine backfires, you
could be burned. Do not drive with
the air cleaner removed, and be care-
ful when working on the engine with
the air cleaner removed.
• Never pour fuel into the throttle body
or attempt to start the engine with
the air cleaner removed. Doing so
could result in serious injury.
IN-CABIN MICROFILTER
The in-cabin microfilter restricts the entry
of airborne dust and pollen particles and
reduces some objectionable outside
odors. The filter is located behind the glove
box. For additional information, see "Main-
tenance and schedules" section of this
manual for change intervals.

AIR CLEANER
8-20Do-it-yourself

Brake pedal:Check the pedal for smooth
operation. If the brake pedal suddenly goes
down further than normal, the pedal feels
spongy or the vehicle seems to take longer
to stop, have your vehicle checked imme-
diately. It is recommended that you visit a
NISSAN dealer for this service. Keep the
floor mat away from the pedal.
Brakes: Check that the brakes do not pull
the vehicle to one side when applied.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only
the parking brake applied. If the parking
brake needs adjustment, it is recom-
mended that you visit a NISSAN dealer for
this service.
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 defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check
that the wipers and washer operate prop-
erly and that the wipers do not streak.
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 maintenance free batter-
ies)*: This vehicle is equipped with a sealed
maintenance free battery. It is recom-
mended that you visit a NISSAN dealer for
service.
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 fluid
level is between the MAX and MIN lines on
the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Check engine drive
belts for wear, fraying or cracking and for
proper tension. Replace any damaged
drive belts.
9-4Maintenance and schedules

Engine oil level*:Check the level af ter
parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, immedi-
ately have the exhaust system inspected. It
is recommended that you visit a NISSAN
dealer for this service. For additional infor-
mation, see “Exhaust gas (carbon monox-
ide)” (P. 5-4).
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.
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 hoses:
Check 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, otherwise rust may form on the
floor pan, frame, fuel lines and around the
exhaust system. At the end of winter, the
underbody should be thoroughly flushed
with plain water, being careful to clean
those areas where mud and dirt may accu-
mulate. For additional information, see
“Cleaning exterior” (P. 7-2 ).
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.
In addition to scheduled maintenance,
your vehicle requires that some items be
checked during normal day-to-day opera-
tion. For additional information, see “Gen-
eral maintenance” (P. 9-2).
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.
