2021 NISSAN FRONTIER ECU

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.

LATCH (Lower Anchors and
Tethers for CHildren) SYSTEM
Your vehicle is equipped with special an-
chor points that are used with LATCH sys-
tem compatible child restraints. This sys-
tem may also be referred to as the ISOFIX
or ISOFIX compatible system. With this sys-
tem, you do not have to use a vehicle seat
belt to secure the child restraint unless the
combined weight of the child and child re-
straint exceeds 65 lbs., (29.5 kg). If the com-
bined weight of the child and child restraint
is greater than 65 lbs. (29.5 kg) use the vehi-cle’s seat belt (not the lower anchors) to
install the child restraint. Be sure to follow
the child restraint manufacturer’s instruc-
tions for installation.
The LATCH lower anchor points are pro-
vided to install child restraints in the rear
outboard seating positions only. Do not at-
tempt to install a child restraint in the cen-
ter position using the LATCH lower an-
chors.

LATCH compatible child restraints include
two rigid or webbing-mounted attach-
ments that can be connected to two an-
chors located at certain seating positions
in your vehicle. With this system, you do not
have to use a vehicle seat belt to secure the
child restraint. Check your child restraint for
a label stating that it is compatible with
LATCH. This information may also be in the
instructions provided by the child restraint
manufacturer.When installing a child restraint, carefully
read and follow the instructions in this
manual and those supplied with the child
restraint.

REAR-FACING CHILD RESTRAINT
INSTALLATION USING LATCH (Crew
Cab models)
For additional information, refer to all Warn-
ings and Cautions in the “Child safety” and
“Child restraints” sections of this manual
before installing a child restraint.
Do not use the lower anchors if the com-
bined weight of the child and the child re-
straint exceeds 65 lbs. (29.5 kg). If the com-
bined weight of the child and the child
restraint is greater than 65 lbs., (29.5 kg) use
the vehicle's seat belt (not the lower an-
chors) to install the child restraint. Be sure
to follow the child restraint manufacturer's
instructions for installation.
Follow these steps to install a rear-facing
child restraint in the rear seats using the
LATCH system:
1. Position the child restraint on the seat.Always follow the child restraint manu-
facturer's instructions. 2. Secure the child restraint anchor at-
tachments to the LATCH lower anchors.
Check to make sure the LATCH attach-
ment is properly attached to the lower
anchors.

3. For child restraints that are equippedwith webbing-mounted attachments,
remove any additional slack from the
anchor attachments. Press downward
and rearward firmly in the center of the
child restraint with your hand to com-
press the vehicle seat cushion and seat-
back while tightening the webbing of
the anchor attachments. 4. Af ter attaching the child restraint, test it
before you place the child in it. Push it
from side to side while holding the child
restraint near the LATCH attachment
path. The child restraint should not
move more than 1 inch (25 mm), from
side to side. Try to tug it forward and
check to see if the LATCH attachment
holds the restraint in place. If the re-
straint is not secure, tighten the LATCH
attachment as necessary, or put the re-
straint in another seat and test it again.
You may need to try a different child
restraint or try installing by using the vehicle seat belt (if applicable). Not all
child restraints fit in all types of vehicles.
5. Check to make sure the child restraint is properly secured prior to each use. If the
child restraint is loose, repeat steps 2
through 4.

2. Move the front passenger's seat into thefull forward position. Then move the
front seatback to the upright or tilted
forward position. Position the child re-
straint on the jump seat. The direction of
the child restraint depends on the type
of the child restraint and the size of the
child. Always follow the child restraint
manufacturer's instructions.
3. Position the child restraint on the seat. Always follow the child restraint manu-
facturer's instructions. 4. Secure the child restraint anchor at-
tachments to the LATCH lower anchors.
