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.1-19) and “Child restraints” (P.1-22) 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
the rear seats:
SSS0100
Rear-facing — step 1
1. Child restraints for infants must be used
in the rear-facing direction and there-
fore must not be used in the front seat.
Position the child restraint on the seat.
Always follow the restraint manufac-
turer’s instructions.

1-32Safety — Seats, seat belts and supplemental restraint system
SSS0657
Rear-facing — step 5
5. Remove any additional slack from the seat belt; press downward and rearward
firmly in the center of the child restraint
to compress the vehicle seat cushion and
seatback while pulling up on the seat
belt.
SSS0658
Rear-facing — step 6
6. After attaching the child restraint, test it before you place the child in it. Push it
from side to side while holding the child
restraint near the seat belt path. The
child restraint should not move more
than 1 inch (25 mm), from side to side.
Try to tug it forward and check to see if
the belt holds the restraint in place. If the
restraint is not secure, tighten the seat
belt as necessary, or put the restraint in
another seat and test it again. You may
need to try a different child restraint. Not
all child restraints fit in all types of
vehicles.
7. Check to make sure that the child restraint is properly secured prior to each use. If the seat belt is not locked, repeat
steps 1 through 6.
After the child restraint is removed and the
seat belt fully retracted, the ALR mode (child
restraint mode) is canceled.
FORWARD-FACING CHILD RE-
STRAINT INSTALLATION USING
LATCH
For additional information, refer to all
Warnings and Cautions in the “Child safety”
and “Child restraints” sections before instal-
ling 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.

SSS0645
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.
SSS0647
Forward-facing — step 4
4. For child restraints that are equipped with webbing-mounted attachments, re-
move any additional slack from the
anchor attachments. Press downward
and rearward firmly in the center of the
child restraint with your knee to com-
press the vehicle seat cushion and seat-
back while tightening the webbing of the
anchor attachments.
5. Tighten the tether strap according to the manufacturer’s instructions to remove
any slack.

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 forward-facing child
restraints with the LATCH lower anchor
attachments.
First, secure the child restraint with the
LATCH lower anchors.
1. Position the top tether strap
over the
seatback.
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.
2. Secure the tether strap to the tether anchor point
as shown.
3. Tighten the tether strap according to the manufacturer’s instructions to remove
any slack.
If you have any questions when installing a
top tether strap, it is recommended you visit an INFINITI retailer for this service.

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
restraints 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 or headrest to obtain the

If the seating position does not have an
adjustable head restraint or headrest
and it is interfering with the proper child
restraint 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 restraint
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 (rear seat installation
only). See “Installing top tether strap”
(P.1-38). 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.

BOOSTER SEATS
For additional information on installing a
booster seat in your vehicle, follow the
instructions outlined in this section.
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.
