ECU NISSAN SENTRA 2023 User Guide

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
anchors. 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 manu-
facturer’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
system compatible child restraints. This
system may also be referred to as the
ISOFIX or ISOFIX compatible system. With
this system, you do not have to use a ve-
hicle seat belt to secure the child restraint
unless the combined weight of the child
and child restraint exceeds 65 lbs. (29.5 kg).
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 an-
chors) to install the child restraint. Be sure to
follow the child restraint manufacturer’s in-
structions 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 (404 mm). Before
attempting 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 over-
load the anchor in a collision, which
could increase the risk of the occu-
pant’s serious injury or death.
When installing the CRS in the center
rear seating position with the inboard
LATCH anchors, be careful to ensure any
occupant or CRS in the outboard seat-
ing positions is properly restrained
using the vehicle seat belt and there is
no interference with the center CRS
installation. If the outboard 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.

Forward-facing (front passenger seat) –
step 1
1-36Safety-Seats, seat belts and supplemental restraint system

Follow these steps to install a forward-facing
child restraint using the vehicle seat belt in
the rear seats or in the front passenger seat:
1.If you must install a child restraint in the
front seat, it should be placed in a
forward-facing direction only. Move the
seat to the rearmost position. Child re-
straints for infants must be used in the
rear-facing direction and, therefore,
must not be used in the front seat.
2. Position the child restraint on the seat. Always follow the child restraint manu-
facturer’s instructions.
The back of the child restraint should be
secured against the vehicle seatback.
If necessary, adjust or remove the head
restraint/headrest to obtain the correct
child restraint fit. If the head restraint/
headrest is removed, store it in a secure
place. Be sure to reinstall the head
restraint/headrest when the child re-
straint is removed. For additional infor-
mation, see “Head restraints/headrests”
(P. 1-8).
If the seating position does not have an
adjustable head restraint/headrest and
it is interfering with the proper child re-
straint fit, try another seating position or
a different child restraint. 3. Route the seat belt tongue through the
child restraint and insert it into the
buckle until you hear and feel the latch
engage. Be sure to follow the child re-
straint manufacturer’s instructions for
belt routing.
If the child restraint is equipped with a
top tether strap, route the top tether
strap and secure the tether strap to the
tether anchor point. For additional infor-
mation, see “Installing top tether strap”
(P. 1-40). Do not install child restraints that require
the use of a top tether strap in seating
