ECU NISSAN FRONTIER 2023 Manual Online

Summer tires
NISSAN specifies summer tires on some
models to provide superior performance
on dry roads. Summer tire performance is
substantially reduced in snow and ice.
Summer tires do not have the tire traction
rating “M&S” on the tire sidewall.
If you plan to operate your vehicle in snowy
or icy conditions, NISSAN recommends the
use of SNOW tires or ALL SEASON tires on all
four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rat-
ing to the original equipment tires. If you do
not, it can adversely affect the safety and
handling of your vehicle.
Generally, snow tires have lower speed rat-
ings than factory equipped tires and may
not match the potential maximum vehicle
speed. Never exceed the maximum speed
rating of the tire.
If you install snow tires, they must be the
same size, brand, construction and tread
pattern on all four wheels.For additional traction on icy roads, stud-
ded tires may be used. However, some U.S.
states and Canadian provinces prohibit
their use. Check local, state and provincial
laws before installing studded tires. Skid
and traction capabilities of studded snow
tires on wet or dry surfaces may be poorer
than that of non-studded snow tires.
TIRE CHAINS
Use of tire chains may be prohibited ac-
cording to location. Check the local laws
before installing tire chains. When installing
tire chains, make sure they are the proper
size for the tires on your vehicle and are
installed according to the chain manufac-
turer's suggestions.
Use only SAE class “S”
chains. Class “S” chains are used on ve-
hicles with restricted tire to vehicle clear-
ance. Vehicles that can use Class “S” chains
are designed to meet the minimum clear-
ances between the tire and the closest ve-
hicle suspension or body component re-
quired to accommodate the use of a
winter traction device (tire chains or
cables). The minimum clearances are de-
termined using the factory equipped tire
size. Other types may damage your vehicle.
Use chain tensioners when recommended
by the tire chain manufacturer to ensure a
tight fit. Loose end links of the tire chain must be secured or removed to prevent
the possibility of whipping action damage
to the fenders or underbody. If possible,
avoid fully loading your vehicle when using
tire chains. In addition, drive at a reduced
speed. Otherwise, your vehicle may be
damaged and/or vehicle handling and
performance may be adversely affected.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Do not use tire chains on dry roads. Driving
with chains in such conditions can cause
damage to the various mechanisms of the
vehicle due to some overstress.
Use only the 2WD range when driving on
clear paved roads.
8-40Do-it-yourself

Doors and engine hood:Check that the
doors and engine hood operate properly.
Also ensure that all latches lock securely.
Lubricate hinges, latches, latch pins, rollers
and links if necessary. Make sure that the
secondary latch keeps the hood from
opening when the primary latch is
released.
When driving in areas using road salt or
other corrosive materials, check lubrica-
tion frequently.
Check that the gas stays or struts properly
and securely hold the hood, trunk, or rear
hatch fully open. If the hood, trunk, or rear
hatch is not held open, have the gas stays
or struts replaced.
Lights*: Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and in-
stalled securely. Also check headlight aim.
Road wheel nuts (lug nuts)*: When check-
ing the tires, make sure no wheel nuts are
missing, and check for any loose wheel
nuts. Tighten if necessary. Tire rotation*:
Rotate tires at the specified
interval shown in the maintenance
schedule.
Tires*: Check the pressure with a gauge
of ten and always prior to long distance
trips. If necessary, adjust the pressure in all
tires, including the spare, to the pressure
specified. Check carefully for damage, cuts
or excessive wear.
Tire Pressure Monitoring System (TPMS)
tire pressure sensor: It is recommended
that you replace the tire pressure sensor
assembly when the tires are replaced due
to wear or age.
Wheel alignment and balance: If the ve-
hicle should pull to either side while driving
on a straight and level road, or if you detect
uneven or abnormal tire wear, there may
be a need for wheel alignment. If the steer-
ing wheel or seat vibrates at normal high-
way speeds, wheel balancing may be
needed.
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet. Windshield:
Clean the windshield on a
regular basis. Check the windshield at least
every six months for cracks or other dam-
age. Have a damaged windshield repaired
by a qualified repair facility. It is recom-
mended that you have a damaged wind-
shield repaired by a NISSAN dealer, or a
NISSAN Certified Collision Center. To locate
a collision center in your area, refer to
http://collision.nissanusa.com.
Windshield wiper blades*: Check for
cracks or wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should
be checked on a regular basis, such as

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.

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.

5. Determine the combined weightof luggage and cargo being
loaded on the vehicle. That weight
may not safely exceed the avail-
able cargo and luggage load ca-
pacity calculated in step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be
transferred to your vehicle. Con-
sult this manual to determine
how this reduces the available
cargo and luggage load capacity
of your vehicle.
Before driving a loaded vehicle, con-
firm that you do not exceed the
GVWR or the GAWR for your vehicle.
For additional information, see “Mea-
surement of weights” (P. 10-25).
Also check tires for proper inflation
pressures. For additional informa-
tion, see “Tire and Loading Informa-
tion label” (P. 8-34).
SECURING THE LOAD
For your convenience, tie down hooks (if so
equipped) are placed at each corner of the
truck box. These may be used to help se-
cure cargo loaded into the truck box.
WARNING
• Properly secure all cargo with ropes
or straps to help prevent it from slid-
ing or shif ting. Do not place cargo
higher than the seatbacks. In a sud-
den stop or collision, unsecured
cargo could cause personal injury.
• Do not load your vehicle any heavier
than the GVWR or the maximum front
and rear GAWRs. If you do, parts of
your vehicle can break, tire damage
could occur, or it can change the way
your vehicle handles. This could re-
sult in loss of control and cause per-
sonal injury.

UTILI-TRACK® CHANNEL SYSTEM
(if so equipped)
1. Side channels
2. Header channel
WARNING
• Properly install and tighten the tie-
down cleats into the Utili-track®
channel system. Also, do not attach
any rope or straps directly to the
channel. Failure to properly install
the tie-down cleats or attaching
ropes or straps directly to the chan-
nel can cause the cargo to become
unsecured. In a sudden stop or colli-
sion, unsecured cargo could cause
personal injury.
• Properly secure all cargo with ropes
or straps to help prevent it from slid-
ing or shif ting. In a sudden stop or
collision, unsecured cargo could
cause personal injury.
The Utili-track® channel system allows you
to move tie-down clamps in the bed to the
best location to secure a load.
The tie-down cleats must be installed so
the clamp is properly seated in the notches
in the rail. If the tie-down cleat is not seated
in the notches, it will not be flush with the
rail and cannot be properly tightened.
The bolt in the center of the cleat must be
tightened hand tight 20 – 40 in-lbs. (2.27 -
4.6 N·m). Check the tightness of the tie-down cleat
periodically during a trip to make sure the
center bolt has not become loose.
Install the tie-down cleat as follows:
1. Remove the side channels by sliding
them out the back of the truck bed.
Properly store the side channels.
2. Loosen the center bolt completely.

WARNING
Do not install accessories over the gap
between the front and rear side chan-
nels. Doing this could affect the rear
structure in certain rear impacts, which
could result in serious injury.LOADING TIPS
• The GVW must not exceed GVWR or GAWR as specified on the F.M.V.S.S./
C.M.V.S.S. certification label.
• Do not load the front and rear axle to the GAWR. Doing so will exceed
the GVWR.
WARNING
• Properly secure all cargo with
ropes or straps to help prevent
it from sliding or shif ting. Do
not place cargo higher than the
seatbacks. In a sudden stop or
collision, unsecured cargo
could cause personal injury.
• Do not load your vehicle any
heavier than the GVWR or the
maximum front and rear
GAWRs. If you do, parts of your
vehicle can break, tire damage
could occur, or it can change
the way your vehicle handles.
This could result in loss of con-
trol and cause personal injury.

1 correct installation, 2 incorrect installation
10-24Technical and consumer information

•Overloading not only can
shorten the life of your vehicle
and the tire, but can also cause
unsafe vehicle handling and
longer braking distances. This
may cause a premature tire
failure which could result in a
serious accident and personal
injury. Failures caused by over-
loading are not covered by the
vehicle’s warranty.MEASUREMENT OF WEIGHTS
Secure loose items to prevent
weight shif ts that could affect the
balance of your vehicle. When the ve-
hicle is loaded, drive to a scale and
weigh the front and the rear wheels
separately to determine axle loads.
Individual axle loads should not ex-
ceed either of the Gross Axle Weight
Ratings (GAWR). The total of the axle
loads should not exceed the Gross
Vehicle Weight Rating (GVWR). These
ratings are given on the vehicle cer-
tification label. If weight ratings are
exceeded, move or remove items to
bring all weights below the ratings.
Do not use a slide-in camper with your
vehicle.
SPECIAL BODY VEHICLES
Some vehicles are equipped with commer-
cial or camper bodies. However, this Own-
er's Manual does not cover these options.
For additional information, refer to the
body manufacturer's instruction manual.

Technical and consumer information10-25

TOWING SAFETY
Trailer hitch
Your vehicle may be equipped with an op-
tional trailer tow package. The trailer tow
package includes a receiver-type frame
mounted hitch. This hitch is rated for the
maximum towing capacity of this vehicle
when the proper towing equipment is
used. Choose a proper ball mount and
hitch ball that is rated for the trailer to be
towed. Genuine NISSAN ball mounts and
hitch balls are available from a NISSAN
dealer.
If your vehicle is not equipped with the op-
tional trailer tow package, check the tow-
ing capacity of your bumper hitch or
receiver-type frame mounted hitch.
Choose a proper hitch for your vehicle and
trailer. A Genuine NISSAN trailer hitch is
available from a NISSAN dealer. Make sure
the trailer hitch is securely attached to the
vehicle to help avoid personal injury or
property damage due to sway caused by
crosswinds, rough road surfaces or pass-
ing trucks.
WARNING
Trailer hitch components have specific
weight ratings. Your vehicle may be ca-
pable of towing a trailer heavier than
the weight rating of the hitch compo-
nents. Never exceed the weight rating
of the hitch components. Doing so can
cause serious personal injury or prop-
erty damage.
Hitch ball
Choose a hitch ball of the proper size and
weight rating for your trailer:
• The required hitch ball size is stamped on most trailer couplers. Most hitch balls
also have the size printed on the top of
the ball.
• Choose the proper class hitch ball based on the trailer weight.
• The diameter of the threaded shank of the hitch ball must be matched to the ball
mount hole diameter. The hitch ball
shank should be no more than 1/16”
smaller than the hole in the ball mount.
• The threaded shank of the hitch ball must be long enough to be properly secured to
the ball mount. There should be at least 2
threads showing beyond the lock washer
and nut.
Ball mount
The hitch ball is attached to the ball mount
and the ball mount is inserted into the
hitch receiver. Choose a proper class ball
mount based on the trailer weight. Addi-
tionally, the ball mount should be chosen
to keep the trailer tongue level with the
ground.
Technical and consumer information10-33

WARNING
• Do not use axle-mounted hitches.
• Do not modif y the vehicle exhaust
system, brake system, etc. to install a
trailer hitch.
• To reduce the possibility of addi-
tional damage if your vehicle is
struck from the rear, where practical,
remove the ball mount from the re-
ceiver when not in use.
•
Regularly check that all trailer hitch
mounting bolts are securely mounted.
Tire pressures
• When towing a trailer, inflate the
vehicle tires to the recommended
cold tire pressure indicated on the
Tire and Loading Information label.
• Trailer tire condition, size, load rat- ing and proper inflation pressure
should be in accordance with
the trailer and tire manufacturer's
specifications.
Safety chains
Always use suitable safety chains between
your vehicle and the trailer. The safety
chains should be crossed and should be
attached to the hitch, not to the vehicle
bumper or axle. The safety chains can be
attached to the bumper if the hitch ball is
mounted to the bumper. Be sure to leave
enough slack in the chains to permit turn-
ing corners.
Trailer lights
CAUTION
When splicing into the vehicle electrical
system, a commercially available power-
type module/converter must be used to
provide power for all trailer lighting. This
unit uses the vehicle battery as a direct
power source for all trailer lights while
using the vehicle tail light, stop light and
turn signal circuits as a signal source.
The module/converter must draw no
more than 15 milliamps from the stop
and tail lamp circuits. Using a module/
converter that exceeds these power re-
quirements may damage the vehicle's
electrical system. See a reputable trailer
dealer to obtain the proper equipment
and to have it installed.
Trailer lights should comply with federal
and/or local regulations. For assistance in
hooking up trailer lights, it is recommended
that you visit a NISSAN dealer or reputable
trailer dealer. Vehicles equipped with the
optional trailer tow package are equipped
with a 7-pin trailer harness connector. A flat
4–pin harness is available from your dealer
for vehicles without a tow package. If your
trailer is equipped with a flat 4-pin connec-
tor, an adapter will be needed to connect
the trailer lights to the vehicle. Adapters are
available at auto parts stores and hitch
retailers.
Trailer brakes
If your trailer is equipped with a braking
system, make sure it conforms to federal
and/or local regulations and that it is prop-
erly installed.
Vehicles equipped with a 7–pin trailer har-
ness connector are pre-wired for a trailer
brake controller. It is recommended that
you visit a NISSAN dealer for a trailer brake
adapter harness.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system.
