3. Position the lap belt portionlow and snug
on the hips
OBas shown.
4. Pull the shoulder belt portion toward the retractor to take up extra slack
OC. Be sure
the shoulder belt is routed over your
shoulder and across your chest.
The front passenger seat and the rear seating
positions three-point seat belts have two
modes of operation:
• Emergency Locking Retractor (ELR)
• Automatic Locking Retractor (ALR)
The ELR mode allows the seat belt to extend
and retract to allow the driver and passen-
gers some freedom of movement in the seat. The ELR locks the seat belt when the vehicle
slows down rapidly or during certain impacts.
The ALR mode (child restraint mode) locks
the seat belt for child restraint installation.
When the ALR mode is activated, the seat
belt cannot be extended again until the seat
belt tongue is detached from the buckle and
fully retracted. The seat belt returns to the
ELR mode after the seat belt fully retracts.
For additional information, see “Child re-
straints” (P. 1-22).
The ALR mode should be used only for child
restraint installation. During normal seat
belt use by an occupant, the ALR mode
should not be activated. If it is activated, it
may cause uncomfortable seat belt tension.
It can also change the operation of the front
passenger air bag. For additional informa-
tion, see “Front passenger air bag and status
light” (P. 1-51).
WARNING
When fastening the seat belts, be certain
that the seatbacks are completely secured
in the latched position. If they are not com-
pletely secured, passengers may be injured
in an accident or sudden stop.
Unfastening the seat belts
To unfasten the seat belt, press the button on
the buckle
O1. The seat belt automatically
retracts.
Checking seat belt operation
Seat belt retractors are designed to lock seat
belt movement by two separate methods:
• When the seat belt is pulled quickly from the retractor.
• When the vehicle slows down rapidly.
LRS2675WRS0139
Safety-Seats, seat belts and supplemental restraint system1-17

To increase your confidence in the seat belts,
check the operation as follows.
• Grasp the shoulder belt and pull forwardquickly. The retractor should lock and re-
strict further belt movement.
If the retractor does not lock during this
check, get the system checked. It is recom-
mended that you visit an INFINITI retailer for
this service, or to learn more about seat belt
operation.
Shoulder belt height adjustment
(front seats)
The shoulder belt anchor height should be
adjusted to the position best for you. For
additional information, see “Precautions on
seat belt usage” (P. 1-11).
To adjust, push the button and then move the
shoulder belt anchor to the desired position
so that the belt passes over the center of the
shoulder. The belt should be away from your
face and neck, but not falling off of your
shoulder. Release the adjustment button to
lock the shoulder belt anchor into position.
WARNING
• After adjustment, release the adjust-
ment button and try to move the shoul-
der belt anchor up and down to make
sure it is securely fixed in position.
• The shoulder belt anchor height should
be adjusted to the position best for you.
Failure to do so may reduce the effec-
tiveness of the entire restraint system
and increase the chance or severity of
injury in an accident.
• The shoulder belt should rest on the
middle of the shoulder. It must not rest
against the neck.
• Be sure that the seat belt is not twisted
in any way.
• Be sure that the shoulder belt anchor is
secured by trying to move the shoulder
belt anchor up and down after
adjustment.

When the seat belt is not in use and when
folding down the rear seats, hook the rear
seat belts on the seat belt hooks.
SEAT BELT EXTENDERS
If, because of body size or driving position, it
is not possible to properly fit the lap/shoulder
belt and fasten it, an extender that is compat-
ible with the installed seat belts is available
for purchase. The extender adds approxi-
mately 8 in (200 mm) of length and may be
used for all seating positions.Seat belt extenders are available for the:
• Driver and front passenger seating
positions
• Rear seating positions
It is recommended that you visit an INFINITI
retailer for assistance with purchasing an ex-
tender if an extender is required.
WARNING
• Only INFINITI seat belt extenders, made
by the same company which made the
original equipment seat belts, should be
used with INFINITI seat belts.
• Adults and children who can use the
standard seat belt should not use an ex-
tender. Such unnecessary use could re-
sult in serious personal injury in the event
of an accident.
• Never use seat belt extenders to install
child restraints. If the child restraint is
not secured properly, the child could be
seriously injured or killed in a collision or
a sudden stop.
SEAT BELT MAINTENANCE
• To clean the seat belt webbing, apply a
mild soap solution or any solution recom-
mended for cleaning upholstery or carpet.
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 com-
pletely 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 buck-
les, tongues, retractors, flexible wires and
anchors, work properly. If loose parts, de-
terioration, cuts or other damage on the
webbing is found, the entire seat belt as-
sembly 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 seri-
ously injured or killed if the seat belt re-
tracts 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 unbuck-
led, 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, see “Child restraints”
(P. 1-22).
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,
see “Child restraints” (P. 1-22).
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, see “Supplemental
Restraint System (SRS)” (P. 1-41).INFANTS
Infants up to at least 1 year old should be
placed in a rear facing child restraint.
INFINITI recommends that infants and small
children be placed in child restraints. You
should choose a child restraint that fits your
vehicle and always follow the manufacturer's
instructions for installation and use.
SMALL CHILDREN
Children that are over 1 year old and weigh at
least 9 kg (20 lbs.) 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
CHILD SAFETY
1-20Safety-Seats, seat belts and supplemental restraint system

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. For
a 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 hipsor 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 adjusted head restraint/headrest?
• Will the child be able to stay in position for 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.
LRS2690
Safety-Seats, seat belts and supplemental restraint system1-21

“Forward-facing child restraint in-
stallation using the seat belts”
(P. 1-34).
– Even with the INFINITI Advanced Air
Bag System, never install a rear-
facing child restraint in the front seat.
An inflating air bag could seriously in-
jure or kill a child. A rear-facing child
restraint must only be used in the rear
seat.
– Be sure to purchase a child restraint
that will fit the child and vehicle.
Some child restraints may not fit
properly in your vehicle.
– 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, see “LATCH (Lower
Anchors and Tethers for CHildren) system”
(P. 1-24). 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 certify-
ing that it complies with Federal Motor
Vehicle Safety Standard 213 or Canadian
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 adjustments 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 restraint (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 restraint.
Safety-Seats, seat belts and supplemental restraint system1-23

• Be sure to follow the child restraint manu-facturer's instructions for installation.
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 re-
straint. 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
positions
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 obstruc-
tions over the anchors such as seat belt
webbing or seat cushion material. The
LRS2990
LATCH system lower anchor locations - bench seat

child restraint will not be secured prop-
erly if the lower anchors are obstructed.
– Child restraint anchorages are designed
to withstand only those loads imposed
by correctly fitted child restraints. Un-
der 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 an-
chorages. The child restraint will not be
properly installed using the damaged
anchorages, and a child could be seri-
ously injured or killed in a collision.
