Installing top tether strap
First, secure the child restraint with the
LATCH lower anchors (2nd row captain’s
or bench outboard seating positions only).
1. If necessary, raise or remove the headrestraint 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/head-
rests” (P.1-13) for head restraint or
headrest adjustment, removal and in-
stallation information.
2. Secure the tether strap to the tether anchor point on the back of each seat-
back behind the child restraint.
3. Tighten the tether strap according to the manufacturer’s instructions to remove
any slack. Make sure the head restraint
or headrest does not contact the top
tether strap.
If you have any questions when installing a
top tether strap on the rear seat, 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.1-60)
. When installing a child restraint sys-
tem in the 3rd center position, both
the center seat belt connector tongue
and buckle tongue must be secured.
See “3rd row center seat belt” (P.1-
25).

Forward-facing (front passenger seat) —
step 1
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 vehicle seat
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
correct child restraint fit. 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.1-13) for head
restraint or headrest adjustment, re-
moval and installation information.
If the seating position does not have an
adjustable head restraint or a headrest
and it is interfering with the proper child
restraint fit, try another seating position
or a different child restraint.
SSS0360B
Forward-facing — step 3
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.1-48). 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.
SSS0651
Forward-facing — step 4
4. Pull the shoulder belt until the belt is fully extended. At this time, the seat belt
retractor is in the Automatic Locking
Retractor (ALR) mode (child restraint
mode). It reverts to Emergency Locking
Retractor (ELR) mode when the seat belt
is fully retracted.

Forward-facing — step 6
6. Remove any additional slack from the seat belt; press downward and rearward
firmly in the center of the child restraint
with your knee to compress the vehicle
seat cushion and seatback while pulling
up on the seat belt.
7. Tighten the tether strap according to the manufacturer’s instructions to remove
any slack.
SSS0641
Forward-facing — step 8
8. 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.
9. Check to make sure the child restraint is properly secured prior to each use. If the

seat belt is not locked, repeat steps 2
through 8.
SSS1099
Forward-facing — step 10
10. If the child restraint is installed in the front passenger seat, place the ignition
switch in the ON position. The front
passenger air bag status light
should
illuminate. If this light is not illuminated,
see “Front passenger air bag and status
light” (P.1-60). Move the child restraint
to another seating position. Have the
system checked. It is recommended you
visit an INFINITI retailer for this service.
After the child restraint is removed and the
seat belt is fully retracted, the ALR mode
(child restraint mode) is canceled.

removed. See “Head restraints/head-
rests” (P.1-13) for head restraint or
headrest adjustment, removal and in-
stallation information.
2. Secure the tether strap to the tether anchor point on the back of each seat-
back (2nd row seat) or right side seat-
back (3rd row bench seat) behind the
child restraint.
3. Tighten the tether strap according to the manufacturer’s instructions to remove
any slack. Make sure the head restraint
or headrest does not contact the top
tether strap.
If you have any questions when installing a
top tether strap on the rear seat, it is
recommended you visit an INFINITI retailer
for this service.
BOOSTER SEATS
Precautions on booster seats
WARNING
If a booster seat and seat belt are not
used properly, the risk of a child being
injured 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.
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.
. 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.
LRS0464
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.

adjustable head restraint or a headrest
and it is interfering with the proper

booster seat fit, try another seating
position or a different booster seat.
4. Position the lap portion of the seat belt low and snug on the child’s hips. Be sure
to follow the booster seat manufac-
turer’s instructions for adjusting the seat
belt routing.
5. Pull the shoulder belt portion of the seat belt toward the retractor to take up
extra slack. Be sure the shoulder belt is
positioned across the top, middle portion
of the child’s shoulder. Be sure to follow
the booster seat manufacturer’s instruc-
tions for adjusting the seat belt routing.

PRECAUTIONS ON SUPPLE-
MENTAL RESTRAINT SYSTEM
This Supplemental Restraint System (SRS)
section contains important information con-
cerning the following systems.
.Driver and passenger supplemental
front-impact air bag (INFINITI Advanced
Air Bag System)
. Front seat-mounted side-impact supple-
mental air bag
. Roof-mounted curtain side-impact and
rollover supplemental air bag
. Seat belt with pretensioner
Supplemental front-impact air bag system:
The INFINITI Advanced Air Bag System can
help cushion the impact force to the head
and chest of the driver and front passenger
in certain frontal collisions.
Front seat-mounted side-impact supple-
mental air bag system: This system can help
cushion the impact force to the chest and
pelvis area of the driver and front passenger
in certain side impact collisions. The supple-
mental side air bag is designed to inflate on
the side where the vehicle is impacted.
Roof-mounted curtain side-impact and roll-
over supplemental air bag system: This
system can help cushion the impact force
to the head of occupants in front and rear
(2nd and 3rd) outboard seating positions in certain side impact or rollover collisions. In a
side impact, the curtain air bags are designed
to inflate on the side where the vehicle is
impacted. In a rollover, the curtain air bags
on both sides are designed to inflate. Under
both side-impact and rollover situations, the
curtain air bags will remain inflated for a
short period of time.
These supplemental restraint systems are
designed to
supplement the crash protection
provided by the driver and passenger seat
belts and are not a substitute for them. Seat
belts should always be correctly worn and
the occupant seated a suitable distance
away from the steering wheel, instrument
panel and door finishers. (See “Seat belts”
(P.1-18) for instructions and precautions on
seat belt usage.)
The supplemental air bags operate only
when the ignition switch is in the ON
position.
After pushing the ignition switch to the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7
seconds if the systems are operational.
SUPPLEMENTAL RESTRAINT SYSTEM

SSS0131
SSS0132
WARNING
.The supplemental front air bags or-
dinarily will not inflate in the event of
a side impact, rear impact, rollover, or
lower severity frontal collision. Al-
ways wear your seat belts to help
reduce the risk or severity of injury in
various kinds of accidents.
. The front passenger air bag will not
inflate if the front passenger air bag
status light is lit or if the front
passenger seat is unoccupied. See
“Front passenger air bag and status
light” (P.1-60).
. The seat belts and the front air bags
are most effective when you are
sitting well back and upright in the
seat. The front air bags inflate with
great force. Even with the INFINITI
Advanced Air Bag System, if you are
unrestrained, leaning forward, sitting
sideways or out of position in any
way, you are at greater risk of injury
or death in a crash. You may also
receive serious or fatal injuries from
the front air bag if you are up against
it when it inflates. Always sit back
against the seatback and as far-away
as practical from the steering wheel
or instrument panel. Always use the
