ECU INFINITI QX50 2019 User Guide

– 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 in-
stalled using the damaged anchorage,
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 possible after fitting the child restraint.
– Infants and children should always be placed in an appropriate child re-
straint 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 colli-
sion, loose objects can injure occupants
or damage the vehicle.CAUTION
A child restraint in a closed vehicle can be-
come 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 attachments
that can be connected to these anchors. 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 restraints
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 cer- tifying that it complies with Federal Mo-
tor Vehicle Safety Standard 213 or Cana-
dian 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 re-
straint (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 be-
ing operated. Canadian law requires the top
tether strap on forward-facing child re-
straints be secured to the designated anchor
point on the vehicle.

LATCH (Lower Anchors and
Tethers for CHildren) SYSTEM
Your vehicle is equipped with special anchor
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 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 instructions for installation.
The LATCH lower anchor points are provided
to install child restraints in the following po-
sitions only:
∙ Rear bench seat – outboard seating po- sitions
LATCH lower anchor
WARNING
Failure to follow the warnings and instruc-
tions for proper use and installation 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 rear center position using the LATCH
system anchors. The child restraint
will not be secured properly. – Inspect the lower anchors by inserting
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 ma-
terial. The child restraint 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 in-
stalled using the damaged anchor-
ages, and a child could be seriously in-
jured or killed in a collision.

secured or cargo that contacts the top
tether strap may damage it during a col-
lision. A child could be seriously injured or
killed in a collision if the top tether strap
is damaged.
∙ 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 at-
tach adult seat belts, or other items or
