ECU INFINITI Q50 2023 User Guide

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 possible 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 re-
straint with a harness. Refer to the manu-
facturer’s instructions for minimum and
maximum weight and height recommenda-
tions. INFINITI recommends that small chil-
dren be placed in child restraints that comply
with Federal Motor Vehicle Safety Stan-
dards or Canadian Motor Vehicle Safety
Standards. You should choose a child re-
straint that fits your vehicle and always
follow the manufacturer’s instructions 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 manufacturer.
Once a child outgrows the height or weight
limit of the harness-equipped forward-fa-
cing child restraint, INFINITI recommends
that the child be placed in a commercially
available booster seat to obtain proper seatbelt 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 portion
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 certifying that it
complies with Federal Motor Vehicle Safety
Standards or Canadian Motor Vehicle
Safety Standards.
A booster seat should be used until the child
can pass the seat belt fit test below:
.
Are the child’s back and hips against the
vehicle seatback?
. Is the child able to sit without slouching?
. Do the child’s knees bend easily over the
front edge of the seat with feet flat on
the floor?
. Can the child safely wear the seat belt
(lap belt low and snug across the hips
and shoulder belt across mid-chest and
shoulder)?
. Is the child able to use the properly
adjusted head restraint/headrest? .
Will the child be able to stay in position
for the entire ride?

forward-facing child restraint in
the front seat, see “Forward-
facing child restraint installation
using the seat belts” (P.1-35).
— Even with the INFINITI 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 anchor points are designed to withstand loads from
child restraints that are properly
fitted.
— Never use the anchor points for adult seat belts or harnesses.
— A child restraint with a top tether strap should not be used in the
front passenger seat.
— Keep seatbacks as upright as possible after 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
system or a seat belt. In a sudden
stop or collision, loose objects can
injure occupants or damage the ve-
hicle.
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 in-
clude rigid or webbing-mounted attach-
ments that can be connected to these
anchors.
For details, see “Lower Anchors and Tethers
for CHildren System (LATCH)” (P.1-24).
If you do not have a LATCH compatible child
restraint, the vehicle seat belts can be used.
Several manufacturers offer child restraints
for infants and small children of various
sizes. When selecting any child restraint, keep the following points in mind:
.
Choose only a restraint with a label
certifying that it complies with Federal
Motor Vehicle Safety Standard 213 or
Canadian Motor Vehicle Safety Stan-
dard 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 vehicle is
being operated. Canadian law requires the
top tether strap on forward-facing child
restraints be secured to the designated
anchor point on the vehicle.

Lower Anchors and Tethers for
CHildren System (LATCH)
Your vehicle is equipped with special anchor
points that are used with the LATCH (Lower
Anchors and Tethers for CHildren) 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 vehicle 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 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
instructions 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 compa-
tible child restraints to the lower
anchors shown in the illustration.
(See the following sections of this
Owner’s Manual for installation gui-
dance.)
. Inspect the lower anchors by insert-
ing your fingers into the lower anchor
area. Feel to make sure there are no
obstructions over the anchors such as
seat belt webbing or seat cushion
material. The child restraint will not
be secured properly if the lower
anchors are obstructed.
Child restraint anchorages are designed
to withstand only those loads imposed
by correctly fitted child restraints. 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
Models without rear seat folding:
The LATCH lower anchors are located at the
rear of the seat cushion near the seatback. 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
of 15.6 in (395 mm). Before
attempting to secure a CRS in this seating
position, ensure that the CRS manufac-
turer’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 outboard
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 occupant’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 seating
positions is properly restrained using the
vehicle seat belt and there is no inter-
ference 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.

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 restraint is not
secure, tighten the LATCH attachment
as necessary, or put the restraint 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.

REAR-FACING CHILD RE-
STRAINT INSTALLATION USING
THE SEAT BELTS
WARNING
The three-point seat belt with Auto-
matic Locking Retractor (ALR) must be
used when installing a child restraint.
Failure to use the ALR mode will result in
the child restraint not being properly
secured. The restraint could tip over or
be loose and cause injury to a child in a
sudden stop or collision. Also, it can
change the operation of the front pas-
senger air bag. See “Front passenger air
bag and status light” (P.1-50).
For additional information, refer to all
Warnings and Cautions in the “Child safety”
(P.1-20) and “Child restraints” (P.1-22)
before installing a child restraint.
Do not use the lower anchors if the com-
bined weight of the child and the child
restraint exceeds 65 lbs (29.5 kg). If the combined 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 using the vehicle seat belts in
