ECU NISSAN TITAN 2021 Owner´s Manual

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 re-
leased.
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 in a fully open position. 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 sched-
ule. 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)
transmitter components: Replace the
TPMS transmitter grommet seal, valve core
and cap 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
when performing scheduled maintenance,
cleaning the vehicle, etc.
Accelerator pedal: Check the pedal for
smooth operation and make sure the
pedal does not bind or require uneven ef-
fort. Keep the floor mat away from the
pedal.
Automatic transmission P (Park) posi-
tion mechanism: On a fairly steep hill
check that your vehicle is held securely
with the shif t lever in the P (Park) position
without applying any brakes.
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.
Maintenance and schedules9-3

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 wiper and washer*:
Check
that the wipers and washer operate prop-
erly and that the wipers do not streak.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
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): For vehicles equipped with a sealed
maintenance free battery. It is recom-
mended that you visit a NISSAN dealer for
service.
Battery* (for serviceable batteries):
Check the fluid level in each cell. The fluid
should be at the bottom of the filler open-
ing. Vehicles operated in high tempera-
tures or under severe conditions require
frequent checks of the battery fluid level.
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 brake
fluid level is between the MIN and MAX lines
on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure the drive
belts are not frayed, worn, cracked or oily.
Engine oil level*: Check the level af ter
parking the vehicle on a level surface with
the engine off. Wait more than 10 minutes
for the oil to drain back into the oil pan.

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. 10-33).
Also check tires for proper inflation
pressures. For additional informa-
tion, see “Tire and Loading Informa-
tion label” (P. 8-37).
SECURING THE LOAD
For your convenience, tie down hooks are
placed at each corner of the truck box.
These may be used to help secure 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
3. Channel sections
4. Floor channels
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.
NOTE:
If the bed liner storage bins (if so
equipped) are installed on the vehicle,
use the cleats in the side channel loca-
tions. For additional information on bed
liner storage bins, see “Storage” (P. 2-69). 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 tight-
ened hand tight (20 – 40 in-lbs.)
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 channel protectors by slid-
ing them out the back of the truck bed.
Properly store the channel protectors.
2. Loosen the center bolt completely.

LOADING TIPS
• The GVW must not exceed GVWR orGAWR 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.
• 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.
CREW CAB MODELS
Crew Cab short wheel base models
should not be used to carry a slide-in
camper.
KING CAB® MODELS
This information is provided for you to
properly install a slide-in camper and is
based on the National Highway Traffic
Safety Administration regulations. It is rec-
ommended that, before installing the
camper, you carefully read the following in-
formation and ensure that the camper
meets the specifications.
This information may not apply to some
Canada model vehicles.
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.
TRUCK-CAMPER LOADING
INFORMATION
Technical and consumer information10-31

The total cargo load should not exceed the
truck's cargo weight rating and the camp-
er's center of gravity should fall within the
truck's recommended center of gravity
zone when installed.
WARNING
Overloading or improper loading can
adversely affect vehicle handling, brak-
ing and performance and may lead to
accidents.
VEHICLE LOAD WEIGHT CAPACITY
The vehicle payload weight capacity
shown on the Tire and Loading Information
label indicates the maximum total weight
of passengers, optional equipment (air
conditioning, trailer hitch, etc.) and cargo
that your vehicle is designed to carry.
For additional information, see “Tire and
Loading Information label” (P. 8-37).
Before driving a loaded vehicle, confirm
that you do not exceed the GVWR or the
GAWR for your vehicle. For additional infor-
mation, see “Vehicle loading information”
(P. 10-22).
Also check tires for proper inflation pres-
sures. For additional information, see “Tire
and Loading Information label” (P. 8-37).
MEASUREMENT OF WEIGHTS
Secure loose items to prevent
weight shif ts that could affect the
balance of your vehicle. When the
truck camper is loaded, drive to a
scale and weigh on the front and on
the rear wheels separately to deter-
mine axle loads. Individual axle loads
should not exceed either of the
gross axle weight ratings (GAWR).
The total of the axle loads should not
exceed the gross vehicle weight rat-
ing (GVWR). These ratings are given
on the vehicle certification label that
is located on the lef t side of the ve-
hicle, normally the dash, hinge pillar,
door latch post, or door edge next to
the driver. If weight ratings are ex-
ceeded, move or remove items to
bring all weights below the ratings.
WARNING
Overloading or improper loading of a
trailer and its cargo can adversely af-
fect vehicle handling, braking and per-
formance and may lead to accidents.
CAUTION
• Do not tow a trailer or haul a heavy
load for the first 500 miles (805 km).
Your engine, axle or other parts could
be damaged.
• For the first 500 miles (805 km) that
you tow a trailer, do not drive over 50
mph (80 km/h) and do not make
starts at full throttle. This helps the
engine and other parts of your ve-
hicle wear in at the heavier load.
Your new vehicle was designed to be used
primarily to carry passengers and cargo.
Remember that towing a trailer places ad-
ditional loads on your vehicle's engine,
drive train, steering, braking and other sys-
tems.
TOWING A TRAILER
Technical and consumer information10-33

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 at 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 at a NISSAN dealer. Make sure the
trailer hitch is securely attached to the ve-
hicle to help avoid personal injury or prop-
erty damage due to sway caused by cross-
winds, rough road surfaces or passing
trucks.A hitch used for towing 5th wheel and
gooseneck trailers can also be installed on
your vehicle. Contact a professional sup-
plier of towing equipment to purchase and
have a 5th wheel or gooseneck hitch in-
stalled.
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 information10-39

should install these hitches as it is very im-
portant to mount the hitch correctly to dis-
tribute the king pin weight for the proper
load carrying and sway control perfor-
mance.
The king pin weight should be 15% of the
fully loaded trailer. Make sure the king pin
weight does not cause the gross vehicle
weight to exceed the Gross Maximum
Weight Rating or the rear axle weight to
exceed the Rear Gross Axle Weight rating.
For additional information, see “Maximum
load limits” (P. 10-34).
The weight of the trailer should not exceed
the maximum towing capacity for the ve-
hicle. For additional information, see “Tow-
ing load/specification” chart (P. 10-37).
Make sure the trailer design allows for the
correct vehicle to trailer clearances before
purchasing a 5th wheel trailer.WARNING
• The hitch should not be attached to
or affect the operation of the impact-
absorbing bumper.
• 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 receiver when not in use.
• Regularly check that all trailer hitch
mounting bolts are securely
mounted.
• When towing with the hitch ball
mounted to the rear bumper, do not
make sharp turns. The trailer may
contact the bumper and cause dam-
age to the bumper or trailer.
• When towing a 5th wheel trailer, do
not make sharp turns while driving or
backing. The trailer may contact the
vehicle and cause damage to both
the trailer and vehicle.
CAUTION
• A 5th wheel hitch adapter is neces-
sary to use an af termarket 5th wheel
hitch. A Genuine NISSAN 5th wheel
hitch adapter (as shown) may be
available at a NISSAN dealer.
• Ensure kit components are properly
stored when not in use. Improperly
stowed components could result in
serious personal injury during a colli-
sion or sudden stop.
LTI2305
10-42Technical and consumer information

WARNING
Do not exceed Gross Combined Weight
Rating (GVWR). For additional informa-
tion about GVWR, see “Towing load/
specification” (P. 10-37).
Pre-towing tips
• Be certain your vehicle maintains a level position when a loaded and/or unloaded
trailer is hitched. Do not drive the vehicle if
it has an abnormal nose-up or nose-
down condition; check for improper
tongue load, overload, worn suspension
or other possible causes of either condi-
tion.
• Always secure items in the trailer to pre- vent load shif t while driving.
• Keep the cargo load as low as possible in the trailer to keep the trailer center of
gravity low.
• Load the trailer so approximately 60% of the trailer load is in the front half and 40%
is in the back half. Also make sure the load
is balanced side to side.
• Check your hitch, trailer tire pressure, ve- hicle tire pressure, trailer light operation,
and trailer wheel lug nuts every time you
attach a trailer to the vehicle.
