WARNING
• Always route the shoulder belt over your
shoulder and across your chest. Never
put the belt behind your back, under your
arm or across your neck. The belt should
be away from your face and neck, but not
falling off your shoulder.
• Position the lap belt as low and snug as
possible AROUND THE HIPS, NOT THE
WAIST. A lap belt worn too high could
increase the risk of internal injuries in an
accident.
• Be sure the seat belt tongue is securely
fastened to the proper buckle. •
Do not wear the seat belt inside out or
twisted. Doing so may reduce its
effectiveness.
• Do not allow more than one person to use
the same seat belt.
• Never carry more people in the vehicle
than there are seat belts.
• If the seat belt warning light glows con-
tinuously while the ignition is turned on
with all doors closed and all seat belts
fastened, it may indicate a malfunction
in the system. Have the system checked.
It is recommended that you visit an
INFINITI retailer for this service.
• No changes should be made to the seat
belt system. For example, do not modify
the seat belt, add material, or install de-
vices that may change the seat belt rout-
ing or tension. Doing so may affect the
operation of the seat belt system. Modi-
fying or tampering with the seat belt
system may result in serious personal
injury.
• Once a seat belt pretensioner(s) have ac-
tivated, they cannot be reused and must
be replaced together with the retractor.
It is recommended that you visit an
INFINITI retailer for this service. •
All seat belt assemblies, including retrac-
tors and attaching hardware, should be
inspected after any collision. It is recom-
mended that you visit an INFINITI re-
tailer for this service. INFINITI recom-
mends that all seat belt assemblies in use
during a collision be replaced unless the
collision was minor and the belts show no
damage and continue to operate prop-
erly. Seat belt assemblies not in use dur-
ing a collision should also be inspected
and replaced if either damage or im-
proper operation is noted.
• All child restraints and attaching hard-
ware should be inspected after any colli-
sion. Always follow the restraint manu-
facturer's inspection instructions and
replacement recommendations. The
child restraints should be replaced if they
are damaged.

SEAT BELT WARNING LIGHT
AND CHIME
The driver and front passenger seat is
equipped with an enhanced seat belt reminder
function. If your vehicle is equipped with an
enhanced seat belt reminder function, a visual
and audible alert will operate if a driver or front
passenger seat belt is unbuckled at speeds of
approximately 9 mph (15 km/h) or more under
the following conditions:
• If the driver seat belt is not fastened.
• The front passenger’s seat belt is not fas-tened and the seat is occupied by a passen-
ger for 7 seconds after the ignition switch is
placed in the ON position. • The front passenger’s seat belt is not fas-
tened and objects or external force on the
passenger seat change the seat belt re-
minder classification to Occupied.
The seat belt warning light will flash under
the conditions shown above until the neces-
sary seat belt is securely fastened.
A warning chime will sound for approxi-
mately 90 seconds or until one of the follow-
ing conditions is met:
• The unbuckled front occupant’s seat belt is securely fastened.
• The seat belt reminder function in the front passenger seat no longer detects that the
front passenger seat is occupied.
• The ignition is turned off or the vehicle is placed in P (Park).
The below situations could result in the seat
belt reminder light being illuminated and the
chime sounding, even with no occupant pres-
ent in the passenger seat:
• Heavy objects placed on the seat.
• Someone pushing or pulling on the front passenger seat.
• An object placed under the front passenger seat. • An object placed between the seat cushion
and center console or between the seat
cushion and the door.
• An object hanging on the seat or placed in the seatback pocket.
• A child restraint or other object pressing against the rear of the seatback.
NOTE:
The rear seats are equipped with a seat belt
warning message in the vehicle information
display.
For additional information, see “Vehicle In-
formation Display” (P. 2-19).
INJURED PERSONS
INFINITI recommends that injured persons
use seat belts. Check with your doctor for
specific recommendations.
PREGNANT WOMEN
INFINITI recommends that pregnant women
use seat belts. The seat belt should be worn
snug and always position the lap belt as low
as possible around the hips, not the waist.
Place the shoulder belt over your shoulder
and across your chest. Never run the lap/
shoulder belt over your abdominal area.
Con-
tact your doctor for specific recommendations.

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.

7. Check to make sure the child restraint isproperly secured prior to each use. If the
child restraint is loose, repeat steps 3
through 6.
FORWARD-FACING CHILD
RESTRAINT INSTALLATION
USING THE SEAT BELTS
WARNING
The three-point seat belt with Automatic
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 passenger air bag. For addi-
tional information, see “Front passenger
air bag and status light” (P. 1-51). For additional information, see “Child safety”
(P. 1-20) and “Child restraints” (P. 1-22) be-
fore installing a child restraint.
Do not use the lower anchors if the combined
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 vehi-
cle's seat belt (not the lower anchors) to in-
stall 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 re-
straints 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/headrest to obtain the correct
child restraint fit. If the head restraint/
headrest is removed, store it in a secure
place. Be sure to reinstall the head
restraint/headrest when the child re-
straint is removed. For additional infor-
mation, see “Head restraints/headrests”
(P. 1-7).
If the seating position does not have an
adjustable head restraint/headrest and it
is interfering with the proper child re-
straint fit, try another seating position or a
different child restraint.

10. If the child restraint is installed in thefront passenger seat, place the ignition
switch in the ON position. The front pas-
senger air bag status light
should
illuminate. If this light is not illuminated
see “Front passenger air bag and status
light” (P. 1-51). Move the child restraint
to another seating position. Have the
system checked. It is recommended that
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.

4. 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 that you
visit an INFINITI retailer for this service.
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 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.

3. The booster seat should be positioned onthe 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 informa-
tion, see “Head restraints/headrests”
(P. 1-7). 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 differ-
ent 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 manufacturer’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 posi-
tioned across the top, middle portion of
the child’s shoulder. Be sure to follow the
booster seat manufacturer’s instructions
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” (P. 1-15). 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, see
“Front passenger air bag and status light”
(P. 1-51).
