SEAT BELT MAINTENANCE
∙To clean the seat belt webbing, apply a
mild soap solution or any solution recom-
mended for cleaning upholstery or car-
pet. Then wipe with a cloth and allow the
seat belts to dry in the shade. Do not
allow the seat belts to retract until they
are completely dry.
∙ If dirt builds up in the shoulder belt guide
of the seat belt anchors, the seat belts
may retract slowly. Wipe the shoulder
belt guide with a clean, dry cloth.
∙ Periodically check to see that the seat
belt and the metal components, such as
buckles, tongues, retractors, flexible
wires and anchors, work properly. If loose
parts, deterioration, cuts or other dam-
age on the webbing is found, the entire
seat belt assembly should be replaced.
WARNING
Do not allow children to play with the seat
belts. Most seating positions are equipped
with Automatic Locking Retractor (ALR)
mode seat belts. If the seat belt becomes
wrapped around a child’s neck with the ALR
mode activated, the child can be seriously
injured or killed if the seat belt retracts and
becomes tight. This can occur even if the
vehicle is parked. Unbuckle the seat belt to
release the child. If the seat belt cannot be
unbuckled or is already unbuckled, release
the child by cutting the seat belt with a
suitable tool (such as a knife or scissors) to
release the seat belt.
Children need adults to help protect them.
They need to be properly restrained.
In addition to the general information in this
manual, child safety information is available
from many other sources, including doctors,
teachers, government traffic safety offices,
and community organizations. Every child is
different, so be sure to learn the best way to
transport your child.
There are three basic types of child restraint
systems: ∙ Rear-facing child restraint ∙ Forward-facing child restraint
∙ Booster seat
The proper restraint depends on the child’s
size. Generally, infants up to about 1 year and
less than 20 lbs. (9 kg) should be placed in
rear-facing child restraints. Forward-facing
child restraints are available for children who
outgrow rear-facing child restraints and are
at least 1 year old. Booster seats are used to
help position a vehicle lap/shoulder belt on a
child who can no longer use a forward-facing
child restraint.
WARNING
Infants and children need special protec-
tion. The vehicle’s seat belts may not fit
them properly. The shoulder belt may come
too close to the face or neck. The lap belt
may not fit over their small hip bones. In an
accident, an improperly fitting seat belt
could cause serious or fatal injury. Always
use appropriate child restraints.
All U.S. states and Canadian provinces or
territories require the use of approved child
restraints for infants and small children. For
additional information, refer to “Child re-
straints” in this section.
CHILD SAFETY
Safety—Seats, seat belts and supplemental restraint system1-19

A child restraint may be secured in the vehicle
by using either the LATCH (Lower Anchor
and Tethers for CHildren) system or with the
vehicle seat belt. For additional information,
refer to “Child restraints” in this section.
INFINITI recommends that all pre-teens and
children be restrained in the rear seat. Stud-
ies show that children are safer when prop-
erly restrained in the rear seat than in the
front seat.
This is especially important because your ve-
hicle has a supplemental restraint system
(air bag system) for the front passenger. For
additional information, refer to “Supple-
mental Restraint System (SRS)” in this sec-
tion.
INFANTS
Infants up to at least 1 year old should be
placed in a rear-facing child restraint.
INFINITI recommends that infants be placed
in child restraints that comply with Federal
Motor Vehicle Safety Standards or Canadian
Motor Vehicle Safety Standards. You should
choose a child restraint that fits your vehicle
and always follow the manufacturer’s in-
structions for installation and use.
SMALL CHILDREN
Children that are over 1 year old and weigh at
least 20 lbs. (9 kg) should remain in a rear-
facing child restraint as long as possible up to
the height or weight limit of the child re-
straint. Children who outgrow the height or
weight limit of the rear-facing child restraint
and are at least 1 year old should be secured
in a forward-facing child restraint with a har-
ness. Refer to the manufacturer’s instructions
for minimum and maximum weight and
height recommendations. INFINITI recom-
mends that small children be placed in child
restraints that comply with Federal Motor
Vehicle Safety Standards or Canadian Motor
Vehicle Safety Standards. You should choose
a child restraint that fits your vehicle and
always follow the manufacturer’s instruc-
tions for installation and use.
LARGER CHILDREN
Children should remain in a forward-facing
child restraint with a harness until they reach
the maximum height or weight limit allowed
by the child restraint manufacturer.
Once a child outgrows the height or weight
limit of the harness-equipped forward-facing
child restraint, INFINITI recommends that
the child be placed in a commercially available
booster seat to obtain proper seat belt fit. Fora seat belt to fit properly, the booster seat
should raise the child so that the shoulder belt
is properly positioned across the chest and
the top, middle portion of the shoulder. The
shoulder belt should not cross the neck or
face and should not fall off the shoulder. The
lap belt should lie snugly across the lower hips
or upper thighs, not the abdomen. A booster
seat can only be used in seating positions that
have a three-point type seat belt. The
booster seat should fit the vehicle seat and
have a label certifying that it complies with
Federal Motor Vehicle Safety Standards or
Canadian Motor Vehicle Safety Standards.
A booster seat should be used until the child
can pass the seat belt fit test below:
∙ Are the child’s back and hips against the vehicle seatback?
∙ Is the child able to sit without slouching?
∙ Do the child’s knees bend easily over the front edge of the seat with feet flat on
the floor?
∙ Can the child safely wear the seat belt (lap belt low and snug across the hips and
shoulder belt across mid-chest and
shoulder)?
∙ Is the child able to use the properly ad- justed head restraint/headrest?
1-20Safety—Seats, seat belts and supplemental restraint system

∙ Will the child be able to stay in positionfor the entire ride?
If you answered no to any of these questions,
the child should remain in a booster seat us-
ing a three-point type seat belt. NOTE:
Laws in some communities may follow dif-
ferent guidelines. Check local and state
regulations to confirm your child is using the
correct restraint system before traveling.
WARNING
Never let a child stand or kneel on any seat
and do not allow a child in the cargo area.
The child could be seriously injured or killed
in a sudden stop or collision.

WARNING
Child restraint anchorages are designed to
withstand only those loads imposed by cor-
rectly fitted child restraints. Under no cir-
cumstances are they to be used to attach
adult seat belts, or other items or equip-
ment to the vehicle. Doing so could damage
the child restraint anchorages. The child re-
straint will not be properly installed using
the damaged anchorage, and a child could
be seriously injured or killed in a collision.
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 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 be- hind 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.
A. Low back booster seat
B. High back booster seatBooster 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 Standard
213.
∙ Check the booster seat in your vehicle to be sure it is compatible with the vehicle’s
seat and seat belt system.
LRS2479LRS0453
1-40Safety—Seats, seat belts and supplemental restraint system

∙ Make sure the child’s head will be prop-erly supported by the booster seat or ve-
hicle 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 the child in the booster
seat and check the various adjustments
to be sure the booster seat is compatible
with the child. Always follow all recom-
mended 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 be-
ing operated.
The instructions in this section apply to
booster seat installation in the rear seats or
the front passenger seat.Booster seat installation
WARNING
To avoid injury to child, do not use the
lap/shoulder belt in the Automatic Locking
Retractor (ALR) mode when using a
booster seat with the seat belts.
For additional information, refer to all Warn-
ings and Cautions in the “Child safety,” “Child
restraints” and “Booster seats” sections of
this manual before installing a child restraint.
Follow these steps to install a booster seat in
the rear seats or in the front passenger seat: 1.
If you must install a booster seat in the
front seat, move the seat to the rear-
most position.
2. Position the booster seat on the seat. Only place it in a front-facing direction.
Always follow the booster seat manu-
facturer’s instructions.

Safety—Seats, seat belts and supplemental restraint system1-41

3. The booster seat should be positionedon the vehicle seat so that it is stable.
If necessary, adjust or remove the head
restraint/headrest to obtain the correct
booster seat fit. If the head
restraint/headrest is removed, store it in
a secure place. Be sure to reinstall the
head restraint/headrest when the
booster seat is removed. For additional
information, refer to “Head
restraints/headrests” in this section. If the seating position does not have an
adjustable head restraint/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 manufactur-
er’s instructions for adjusting the seat
belt routing.
5. Pull the shoulder belt portion of the seat belt toward the retractor to take up ex-
tra 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.
6. Follow the warnings, cautions and in- structions for properly fastening a seat
belt shown in “Three-point type seat belt
with retractor” in this section. 7. If the booster seat is installed in the front
passenger seat, place the ignition switch
in the ON position. The front passenger
air bag status light
may or may not
illuminate, depending on the size of the
child and the type of booster seat being
used. For additional information, refer to
“Front passenger air bag and status
light” in this section.
