ECU NISSAN FRONTIER 2021 Owners Manual

WARNING
• Do not ride in a moving vehicle when
the seatback is reclined. This can be
dangerous. The shoulder belt will not
be against your body. In an accident,
you could be thrown into it and re-
ceive neck or other serious injuries.
You could also slide under the lap belt
and receive serious internal injuries. •
For the most effective protection
when the vehicle is in motion, the
seat should be upright. Always sit
well back and upright in the seat with
both feet on the floor and adjust the
seat properly. For additional infor-
mation, refer to “Precautions on seat
belt usage” in this section.
• Af ter adjustment, gently rock in the
seat to make sure it is securely
locked. •
Do not leave children unattended in-
side the vehicle. They could unknow-
ingly activate switches or controls or
make the vehicle move. Unattended
children could become involved in
serious accidents.
• To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, do not
leave children, people who require
the assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve-
hicle on a warm day can quickly be-
come high enough to cause a signifi-
cant risk of injury or death to people
and pets.
• Do not adjust the driver’s seat while
driving so full attention may be given
to vehicle operation. The seat may
move suddenly and could cause loss
of control of the vehicle.
• The seatback should not be reclined
any more than needed for comfort.
Seat belts are most effective when
the passenger sits well back and
straight up in the seat. If the seatback
is reclined, the risk of sliding under
the lap belt and being injured is
increased.

•Head restraints/headrests should be
adjusted properly as they may pro-
vide significant protection against
injury in an accident. Always replace
and adjust them properly if they have
been removed for any reason.
• If the head restraints/headrests are
removed for any reason, they should
be securely stored to prevent them
from causing injury to passengers or
damage to the vehicle in case of sud-
den braking or an accident.
• When returning the seatbacks to the
upright position, be certain they are
completely secured in the latched
position. If they are not completely
secured, passengers may be injured
in an accident or sudden stop.
• Properly secure all cargo to help pre-
vent it from sliding or shif ting. Do not
place cargo higher than the seat-
backs. In a sudden stop or collision,
unsecured cargo could cause per-
sonal injury.
Folding the rear bench seat up (if
so equipped)
To fold the rear bench seat up:
1. Lif t up on the lever, located on the side of the seat, while lif ting the front of the seat
cushion up. 2. Fold the bottom of the seat cushion to-
ward the back of the vehicle until it locks
in place.

3. Repeat this process to raise and securethe seat cushion on the other side of the
vehicle for maximum storage capacity.
To return the rear bench seat to a seating
position, reverse the process. Make sure to
properly push the seat cushion down
into place.
WARNING
• When the vehicle is being used to
carry cargo, properly secure all cargo
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 allow people to ride in any
area of your vehicle that is not
equipped with seats and seat belts.
Be sure everyone in your vehicle is in
a seat and using a seat belt properly.
Never ride in the rear seat unless the
seat bottom cushions are in place
and latched.
• When returning the seatbacks to the
upright position, be certain they are
completely secured in the latched
position. If they are not completely
secured, passengers may be injured
in an accident or sudden stop.
A. Child restraint anchor points
Folding the rear bench seat down
(if so equipped)
The rear bench seatback can be tilted for-
ward to access the child restraint anchor
point locations or the jacking equipment.
To tilt the seatback forward, pull the strap
up
O1and tilt the seatback. The child re-
straint anchor points can be accessed be-
hind the rear bench seatback. The jacking
equipment can be accessed from behind
the passenger's side seatback.

SEAT BELT WARNING LIGHT AND
CHIME
The driver and front passenger seat is
equipped with an enhanced seat belt re-
minder function. If your vehicle is equipped
with an enhanced seat belt reminder func-
tion, a visual and audible alert (Driver’s seat
only) will operate if a driver or front passen-
ger seat belt is unbuckled at speeds of ap-
proximately 9 mph (15 km/h) or more un-
der the following conditions:
• If the driver seat belt is not fastened.• The front passenger’s seat belt is not fas-
tened and the seat is occupied by a pas-
senger for 7 seconds af ter the ignition
switch is placed in the ON position.
• The front passenger’s seat belt is not fas- tened and objects or external force on
the passenger seat change the seat belt
reminder classification to Occupied.
The seat belt warning light will flash under
the conditions shown above until the nec-
essary seat belt is securely fastened.
A warning chime will sound for approxi-
mately 90 seconds or until one of the fol-
lowing conditions is met:
• The unbuckled front occupant’s seat belt is securely fastened.
• The ignition is turned off.
The below situations could result in the
seat belt reminder light being illuminated
and the chime sounding (Driver’s seat only),
even with no occupant present in the pas-
senger seat:
• Heavy objects placed on the seat.
• Someone pushing or pulling on the front passenger seat. • An object placed under the front passen-
ger seat.
• An object placed between the seat cush- ion and center console or between the
seat cushion and the door.
• An object hanging on the seat or placed in the seatback pocket.
• A child restraint or other object pressing against the rear of the seatback.
PREGNANT WOMEN
NISSAN recommends that pregnant
women use seat belts. The seat belt should
be worn snug and always position the lap
belt as low as possible around the hips, not
the waist. Place the shoulder belt over your
shoulder and across your chest. Never run
the lap/shoulder belt over your abdominal
area. Contact your doctor for specific rec-
ommendations.
INJURED PERSONS
NISSAN recommends that injured persons
use seat belts. Check with your doctor for
specific recommendations.

3. Position the lap belt portionlow and
snug on the hips
OBas shown.
4. Pull the shoulder belt portion toward the retractor to take up extra slack
OC.Be
sure the shoulder belt is routed over
your shoulder and across your chest.
The front passenger seat and the rear
seating positions’ three-point seat belts
have two modes of operation:
• Emergency Locking Retractor (ELR)
• Automatic Locking Retractor (ALR) The ELR mode allows the seat belt to ex-
tend and retract to allow the driver and
passengers some freedom of movement
in the seat. The ELR locks the seat belt
when the vehicle slows down rapidly or
during certain impacts.
The ALR mode (child restraint mode) locks
the seat belt for child restraint installation.
When the ALR mode is activated, the seat
belt cannot be extended again until the
seat belt tongue is detached from the
buckle and fully retracted. The seat belt re-
turns to the ELR mode af ter the seat belt
fully retracts. For additional information, re-
fer to “Child restraints” in this section.
The ALR mode should be used only for
child restraint installation. During nor-
mal seat belt use by an occupant, the ALR
mode should not be activated. If it is ac-
tivated it may cause uncomfortable seat
belt tension. It can also change the op-
eration of the front passenger air bag.
For additional information, refer to
“Front passenger air bag and status
light” in this section.
WARNING
When fastening the seat belts, be cer-
tain that the seatbacks are completely
secured in the latched position. If they
are not completely secured, passen-
gers may be injured in an accident or
sudden stop.

gers may be injured in an accident or
sudden stop.
Unfastening the seat belts
To unfasten the seat belt, press the button
on the buckle
O1. The seat belt automati-
cally retracts.
Checking seat belt operation
Seat belt retractors are designed to lock
seat belt movement by two separate
methods:
• When the seat belt is pulled quickly from the retractor
• When the vehicle slows down rapidly
To increase your confidence in the seat
belts, check the operation as follows:
• Grasp the shoulder belt and pull forward quickly. The retractor should lock and re-
strict further belt movement.
If the retractor does not lock during this
check, get the system checked. It is recom-
mended that you visit a NISSAN dealer for
this service or to learn more about seat belt
operation.
WRS0139

All U.S. states and Canadian provinces or
territories require the use of approved child
restraints for infants and small children. For
additional information, refer to “Child re-
straints” in this section.
A child restraint may be secured in the ve-
hicle by using either the LATCH (Lower An-
chors and Tethers for CHildren) system or
with the vehicle seat belt. For additional
information, refer to “Child restraints” in this
section.
NISSAN recommends that all pre-teens
and children be restrained in the rear
seat if available (Crew Cab models). Stud-
ies show that children are safer when
properly restrained in the rear seat than
in the front seat.
This is especially important because
your vehicle has a supplemental re-
straint system (air bag system) for the
front passenger. For additional informa-
tion, refer to “Supplemental Restraint
System (SRS)” in this section.INFANTS
Infants up to at least 1 year old should be
placed in a rear-facing child restraint. NISSAN
recommends that infants be placed in child
restraints that comply with Federal Motor
Vehicle Safety Standards or Canadian Motor
Vehicle Safety Standards. You should choose
a child restraint that fits your vehicle and
always follow the manufacturer's instruc-
tions for installation and use.
SMALL CHILDREN
Children that are over 1 year old and weigh
at least 20 lbs. (9 kg) should remain in a
rear-facing child restraint as long as pos-
sible up to the height or weight limit of the
child restraint. Children who outgrow the
height or weight limit of the rear-facing
child restraint and are at least 1 year old
should be secured in a forward-facing child
restraint with a harness. Refer to the manu-
facturer’s instructions for minimum and
maximum weight and height recommen-
dations. NISSAN recommends that small
children be placed in child restraints that
comply with Federal Motor Vehicle Safety
Standards or Canadian Motor Vehicle
Safety Standards. You should choose a
child restraint that fits your vehicle and al-
ways follow the manufacturer’s instruc-
tions for installation and use.
LARGER CHILDREN
Children should remain in a forward-facing
child restraint with a harness until they
reach the maximum height or weight limit
allowed by the child restraint manufac-
turer.
Once a child outgrows the height or weight
limit of the harness-equipped forward-
facing child restraint, NISSAN recommends
that the child be placed in a commercially
available booster seat to obtain proper
seat belt fit. For a seat belt to fit properly, the
booster seat should raise the child so that
the shoulder belt is properly positioned
across the chest and the top, middle por-
tion of the shoulder. The shoulder belt
should not cross the neck or face and
should not fall off the shoulder. The lap belt
should lie snugly across the lower hips or
upper thighs, not the abdomen. A booster
seat can only be used in seating positions
that have a three-point type seat belt. The
booster seat should fit the vehicle seat and
have a label certif ying that it complies with
Federal Motor Vehicle Safety Standards or
Canadian Motor Vehicle Safety Standards.
1-26Safety-Seats, seat belts and supplemental restraint system

–Child restraint anchorages are de-
signed to withstand only those
loads imposed by correctly fitted
child restraints. Under no circum-
stances are they to be used to at-
tach adult seat belts, or other
items or equipment to the vehicle.
Doing so could damage the child
restraint anchorages. The child re-
straint will not be properly in-
stalled using the damaged an-
chorage, and a child could be
seriously injured or killed in a
collision.
– Never use the anchor points for
adult seat belts, or other items.
– A child restraint with a top tether
strap should not be used in the
front passenger seat (King Cab®
models).
–
Keep seatbacks as upright as pos-
sible af ter fitting the child restraint.
– Infants and children should al-
ways be placed in an appropriate
child restraint while in the vehicle.
• When the child restraint is not in use,
keep it secured with the LATCH sys-
tem or a seat belt. In a sudden stop or
collision, loose objects can injure oc-
cupants or damage the vehicle.
CAUTION
A child restraint in a closed vehicle can
become very hot. Check the seating
surface and buckles before placing a
child in the child restraint.
This vehicle is equipped with a universal
child restraint anchor system, referred to
as the LATCH (Lower Anchors and Tethers
for CHildren) system. Some child restraints
include rigid or webbing-mounted attach-
ments that can be connected to these an-
chors. For additional information, refer to
“LATCH (Lower Anchors and Tethers for
CHildren) system” in this section.
If you do not have a LATCH compatible
child restraint, the vehicle seat belts can be
used.
Several manufacturers offer child re-
straints for infants and children of various
sizes. When selecting any child restraint,
keep the following points in mind:
• Choose only a restraint with a label certi- f ying that it complies with Federal Motor
Vehicle Safety Standard 213 or Canadian
Motor Vehicle Safety Standard 213.
• Check the child restraint in your vehicle to be sure it is compatible with the vehicle's
seat and seat belt system. • If the child restraint is compatible with
your vehicle, place your child in the child
restraint and check the various adjust-
ments to be sure the child restraint is
compatible with your child. Choose a
child restraint that is designed for your
child's height and weight. Always follow
all recommended procedures.
• If the combined weight of the child and child restraint is less than 65 lbs. (29.5 kg),
you may use either the LATCH anchors or
the seat belt to install the child restraint
(not both at the same time).
• If the combined weight of the child and child restraint is greater than 65 lbs. (29.5
kg), use the vehicle’s seat belt (not the
lower anchors) to install the child re-
straint.
• Be sure to follow the child restraint manufacturer’s instructions for installa-
tion.
All U.S. states and Canadian provinces or
territories require that infants and small
children be restrained in an approved
child restraint at all times while the ve-
hicle is being operated. Canadian law re-
quires the top tether strap on forward-
facing child restraints be secured to the
designated anchor point on the vehicle.
