2018 INFINITI Q50 HYBRID ECU

forward-facing child restraint in
the front seat, see “Forward-
facing child restraint installation
using the seat belts” (P.1-29).
— 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.1-20).
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 followthe child restraint manufacturer’s instruc-
tions for installation.
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:
.
Attach LATCH system compatible
child restraints only at the locations
shown in the illustration.
. Do not secure a child restraint in the
center rear seating position using the
LATCH lower anchors. The child re-
straint will not be secured properly.
. 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
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 webbing-mounted attachment
Installing child restraint LATCH
lower anchor attachments
LATCH compatible child restraints include
two rigid or webbing-mounted attachments
that can be connected to two anchors
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 re-
straint manufacturer.

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 1
through 4.
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.1-45).
For additional information, refer to all
Warnings and Cautions in the “Child safety”
(P.1-16) and “Child restraints” (P.1-18) be-
fore 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

removed, store it in a secure place. Be
sure to reinstall the head restraint when
the child restraint is removed. See “Head
restraints/headrests” (P.1-5) for head
restraint adjustment information.
If the seating position does not have an
adjustable head restraint and it is inter-
fering with the proper child restraint fit,
try another seating position or a differ-
ent child restraint.
