ECU NISSAN ALTIMA 2023 User Guide

–The child restraint must be used
and installed properly. Always fol-
low all of the child restraint manu-
facturer's instructions for instal-
lation and use.
– Infants and children should never
be held on anyone's lap. Even the
strongest adult cannot resist the
forces of a collision.
– Do not put a seat belt around both
a child and another passenger.
– NISSAN recommends that all child
restraints be installed in the rear
seat. Studies show that children are safer when properly re-
strained in the rear seat than in
the front seat. If you must install a
forward-facing child restraint in
the front seat, see “Forward-
facing child restraint installation
using the seat belts” (P. 1-38).
– Even with the NISSAN Advanced
Air Bag System, never install a
rear-facing child restraint in the
front seat. An inflating air bag
could seriously injure or kill a child.
A rear-facing child restraint must
only be used in the rear seat.
– Be sure to purchase a child re-
straint that will fit the child and
vehicle. Some child restraints may
not fit properly in your vehicle.
– 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.
– 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.
WRS0256
1-24Safety-Seats, seat belts and supplemental restraint system

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, see
“LATCH (Lower Anchors and Tethers for
CHildren) system” (P. 1-25).
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
restraint.
• Be sure to follow the child restraint manufacturer’s instructions for
installation.
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 ve-
hicle’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 anchor points can be used to
install child restraints in either of the rear
outboard seating positions or in the center
rear seating position. Please refer to the
following section of this Owner’s Manual for
specific information about installing a child
restraint in the center rear seating position
using the LATCH anchors.
LATCH lower anchor
WARNING
Failure to follow the warnings and in-
structions for proper use and installa-
tion of child restraints could result in
serious injury or death of a child or
other passengers in a sudden stop or
collision:
– Only attach LATCH system compat-
ible child restraints to the Lower An-
chors shown in the illustration. For
additional information, refer to the
following sections of this Owner’s
Manual for installation guidance. –
Inspect the lower anchors by insert-
ing your fingers into the lower an-
chor area. Feel to make sure there
are no obstructions over the an-
chors such as seat belt webbing or
seat cushion material. The child re-
straint will not be secured properly if
the lower anchors are obstructed.
Child restraint anchorages are de-
signed to withstand only those loads
imposed by correctly fitted child re-
straints. Under no circumstances are
they to be used to attach adult seat
belts, or other items or equipment to
the vehicle. Doing so could damage the
child restraint anchorages. The child
restraint will not be properly installed
using the damaged anchorage, and a
child could be seriously injured or killed
in a collision.
LATCH lower anchor location
The LATCH lower anchors are located as
shown. A label is attached to the seatback
to help you locate the LATCH lower
anchors.

LATCH in the center rear seating
position
There are no LATCH anchors dedicated to
the center rear seating position. However,
the inboard LATCH anchors belonging to
the two outboard seating positions (indi-
cated by the arrows) can be used together
to secure a CRS in the center rear seating
position. These anchors are separated by a
distance
OAof 16 in (408 mm). Before at-
tempting to secure a CRS in this seating
position, ensure that the CRS manufactur-
er’s instructions permit the use of LATCH
anchors with the spacing indicated above. (These are sometimes referred to as
“shared anchors” or “borrowed anchors.”)
CRS with rigid lower attachments cannot
be installed in the center seat. This type of
CRS should only be installed in the out-
board seating positions.
WARNING
• Never attach two CRS attachments
to the same LATCH anchor. This may
overload the anchor in a collision,
which could increase the risk of the
occupant’s serious injury or death.
• When installing the CRS in the center
rear seating position with the in-
board LATCH anchors, be careful to
ensure any occupant or CRS in the
outboard seating positions is prop-
erly restrained using the vehicle seat
belt and there is no interference with
the center CRS installation. If the out-
board occupants cannot be properly
restrained, consider using the vehicle
seat belt to restrain the CRS in the
center seating position, or moving
the CRS to another position instead.
Installing child restraint LATCH
lower anchor attachments
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.
