FORWARD-FACING CHILD RE-
STRAINT INSTALLATION USING
LATCH
Refer to all Warnings and Cautions in the
“Child safety” and “Child restraints” sections
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 forward-
facing child restraint using the LATCH
system:
1. Position the child restraint on the seat. Always follow the child restraint manu-
facturer’s instructions.

Forward-facing web-mounted — step 2
2. Secure the child restraint anchor attach-
ments to the LATCH lower anchors.
Check to make sure the LATCH attach-
ment is properly attached to the lower
anchors.
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. See “Installing top
tether strap” (P.1-34). Do not install child
restraints that require the use of a top
tether strap in seating positions that do
not have a top tether anchor.
SSS0646
Forward-facing rigid-mounted — step 2
3. The back of the child restraint should be
secured against the vehicle seatback.
If necessary, adjust or remove the head
restraint to obtain the correct child
restraint fit. If the head restraint is
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.1-8) 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.

Installing top tether strap
WARNING
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.

The child restraint top tether strap must be
used when installing the child restraint with
the LATCH lower anchor attachments.
First, secure the child restraint with the
LATCH lower anchors (rear outboard seat-
ing positions only).
1. Flip up the anchor cover from the anchorpoint which is located directly behind the
child restraint.
2. If necessary, raise or remove the head restraint or headrest to position the top
tether strap over the top of the seatback.
If the head restraint or headrest is
removed, store it in a secure place. Be
sure to reinstall the head restraint or
headrest when the child restraint is
removed.
See “Head restraints/headrests” (P.1-
8) for head restraint or headrest adjust-
ment, removal and installation informa-
tion.
Position the top tether strap over the top
of the seatback.
3. Secure the tether strap to the tether anchor point on the rear parcel shelf.
4. Refer to the appropriate child restraint installation procedure steps in this sec-
tion before tightening the tether strap.
If you have any questions when installing a
top tether strap, it is recommended you visit an INFINITI retailer for this service.
FORWARD-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 re-
straint. 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 passenger air
bag. See “Front passenger air bag
and status light” (P.1-50).
. When installing a child restraint sys-
tem in the rear center position, both
the center seat belt connector tongue
and buckle tongue must be secured
(for models with rear seat folding).
See “Rear center seat belt (models
with rear seat folding)” (P.1-18).

Precautions on booster seats
WARNING
If a booster seat and seat belt are not
used properly, the risk of a child being
injured or killed in a sudden stop or
collision greatly increases:
. Make sure the shoulder portion of
the belt is away from the child’s face
and neck and the lap portion of the
belt does not cross the stomach.
. Make sure the shoulder belt is not
behind the child or under the child’s
arm.
. A booster seat must only be installed
in a seating position that has a lap/
shoulder belt.
LRS0455
Booster seats of various sizes are offered by
several manufacturers. When selecting any
booster seat, keep the following points in
mind:
.Choose only a booster seat with a label
certifying that it complies with Federal
Motor Vehicle Safety Standard 213 or
Canadian Motor Vehicle Safety Stan-
dard 213.
. Check the booster seat in your vehicle to
be sure it is compatible with the vehicle’s
seat and seat belt system.
Safety — Seats, seat belts and supplemental restraint system1-39

1-40Safety — Seats, seat belts and supplemental restraint system
LRS0453
.Make sure the child’s head will be
properly supported by the booster seat
or vehicle seat. The seatback must be at
or above the center of the child’s ears.
For example, if a low back booster seat
is chosen, the vehicle seatback must be
at or above the center of the child’s ears.
If the seatback is lower than the center
of the child’s ears, a high back booster
seat
should be used.
LRS0464
. If the booster seat is compatible with
your vehicle, place your child in the
booster seat and check the various
adjustments to be sure the booster seat
is compatible with your child. Always
follow all recommended procedures.
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.
The instructions in this section apply to
booster seat installation in the rear seats or
the front passenger seat.
