seat should be upright. Always sit
well back and upright in the seat with
both feet on the floor and adjust the
seat belt properly.
. 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 can
not be unbuckled or is already un-
buckled, release the child by cutting
the seat belt with a suitable tool
(such as a knife or scissors) to release
the seat belt.
SSS0292
Fastening the seat belts
1. Adjust the seat. (See “Seats” (P.1-2).)
2. Slowly pull the seat belt out of the
retractor and insert the tongue into the
buckle until you hear and feel the latch
engage.
.The retractor is designed to lockduring a sudden stop or on impact.
A slow pulling motion permits the
belt to move, and allows you some
freedom of movement in the seat.
.If the seat belt cannot be pulled from its fully retracted position, firmly pull
the belt and release it. Then smoothly
pull the belt out of the retractor.
SSS0290
3. Position the lap belt portion low and
snug on the hips as shown.
4. Pull the shoulder belt portion toward the retractor to take up extra slack. Be sure
the shoulder belt is routed over your
shoulder and across your chest.
The three-point type seat belts have two
modes of operation:
. Emergency Locking Retractor (ELR)
. Automatic Locking Retractor (ALR)
The Emergency Locking Retractor (ELR)
mode allows the seat belt to extend and
retract to allow the driver and passengers
some freedom of movement in the seat. The
ELR locks the seat belt when the vehicle
slows down rapidly or during impacts.

The Automatic Locking Retractor (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.
WARNING
When fastening the seat belts, be certain
that seatbacks are completely secured in
the latched position. If they are not
completely secured, passengers may be
injured in an accident or sudden stop.
SSS0326
Unfastening the seat belts
To unfasten the seat belt, push the button
on the buckle. 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 belt is pulled quickly from the
retractor.
. When the vehicle slows down rapidly.
To increase your confidence in the seat belts,
check the operation as follows:
. Grasp the shoulder belt and pull forward
quickly. The retractor should lock and restrict further belt movement.
If the retractor does not lock during this
check, get the system checked. It is recom-
mended you visit an INFINITI retailer for this
service, or to learn more about seat belt
operation.

Center of rear seat
The center seat belt buckle is identified by
the CENTER mark. The center seat belt
tongue can be fastened onlyinto the center
seat belt.
SSS0294A
Shoulder belt height adjustment
(front seats)
The shoulder belt anchor height should be
adjusted to the position best for you. (See
“Precautions on seat belt usage” (P.1-12).)
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
shoulder 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 effectiveness of the entire
restraint system and increase the
chance or severity of injury in an
accident.
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 compatible with the installed seat belts is
available that can be purchased. The ex-
tender adds approximately 8 in (200 mm) of
length and may be used for either the driver
or front passenger seating position. It is
recommended you visit an INFINITI retailer
for assistance with purchasing an extender if
an extender is required.

WARNING
.It is recommended only INFINITI seat
belt extenders, made by the same
company which made the original
equipment seat belts, be used with
the INFINITI seat belts.
. Adults and children who can use the
standard seat belt should not use an
extender. Such unnecessary use could
result 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 re-
commended for cleaning upholstery or
carpets. 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 da-
mage 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 Re-
tractor (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 can not be
unbuckled or is already unbuckled, re-
lease 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.

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.
