WARNING
• Do not ride in a moving vehicle when the
seatback is reclined. This can be danger-
ous. The shoulder belt will not be against
your body. In an accident, you could be
thrown into it and receive neck or other
serious injuries. You could also slide un-
der the lap belt and receive serious inter-
nal injuries. •
For the most effective protection when
the vehicle is in motion, the seat should
be upright. Always sit well back and up-
right in the seat with both feet on the
floor and adjust the seat properly. For
additional information, see “Precautions
on seat belt usage” (P. 1-11).
• After adjustment, gently rock in the seat
to make sure it is securely locked.
• Do not leave children unattended inside
the vehicle. They could unknowingly ac-
tivate switches or controls or make the
vehicle move. Unattended children could
become involved in serious accidents. •
To help avoid risk of injury or death
through unintended operation of the ve-
hicle and/or its systems, do not leave
children, people who require the assis-
tance of others or pets unattended in
your vehicle. Additionally, the tempera-
ture inside a closed vehicle on a warm day
can quickly become high enough to cause
a significant risk of injury or death to
people and pets.
• Do not adjust the driver’s seat while
driving so full attention may be given to
vehicle operation. The seat may move
suddenly and could cause loss of control
of the vehicle.
• The seatback should not be reclined any
more than needed for comfort. Seat
belts are most effective when the pas-
senger sits well back and straight up in
the seat. If the seatback is reclined, the
risk of sliding under the lap belt and be-
ing injured is increased.
CAUTION
When adjusting the seat positions, be sure
not to contact any moving parts to avoid
possible injuries and/or damage.

back in position.
The recline feature allows adjustment of the
seatback for occupants of different sizes for
added comfort and to help obtain proper seat
belt fit. For additional information, see “Pre-
cautions on seat belt usage” (P. 1-11). Also,
the seatback can be reclined to allow occu-
pants to rest when the vehicle is stopped and
the shift lever is in P (Park).

FLEXIBLE SEATING
WARNING
• Never allow anyone to ride in the cargo
area or on the rear seats when they are in
the fold-down position. In a collision,
people riding in these areas without
proper restraints are more likely to be
seriously injured or killed. •
Do not allow people to ride in any area of
your vehicle that is not equipped with
seats and seat belts. Be sure everyone in
your vehicle is in a seat and using a seat
belt properly.
• Do not allow more than one person to use
the same seat belt.
• Do not fold down the rear seats when
occupants are in the rear seat area or any
luggage is on the rear seats.
– Make sure that the seat path is clear
before moving the seat.
– Be careful not to allow hands or feet
to get caught or pinched in the seat.
• Head restraints/headrests should be ad-
justed properly as they may provide sig-
nificant protection against injury in an
accident. Always replace and adjust
them properly if they have been removed
for any reason.
• If the head restraints/headrests are re-
moved for any reason, they should be se-
curely stored to prevent them from caus-
ing injury to passengers or damage to the
vehicle in case of sudden braking or an
accident.

•When returning the seatbacks to the up-
right position, be certain they are com-
pletely secured in the latched position. If
they are not completely secured, passen-
gers may be injured in an accident or sud-
den stop.
• Properly secure all cargo to help prevent
it from sliding or shifting. Do not place
cargo higher than the seatbacks. In a
sudden stop or collision, unsecured cargo
could cause personal injury.
Folding the rear bench seat
To fold the rear bench seat flat for maximum
cargo hauling:
1. Remove any object from the rear seat sit- ting area
2. Move each side of the rear seat com- pletely backwards. For additional infor-
mation, see “Forward and backward”
(P. 1-4).
3. Make sure that the head restraints/ headrests are lowered. For additional in-
formation, see “Lower” (P. 1-11). 4. Stow the rear seat belts in the seat belt
hooks found on the sides of the vehicle.
5. Lift up on the recline lever on the side of the outboard seats or pull the lever on
either side of the cargo area to fold the
seatbacks flat.
• If one of the rear seatbacks does not fold flat completely, move the corre-
sponding Front Power Seat forward,
push up the seatback until it latches in
place and remove the head restraints/
headrests. For additional information,
see “Remove” (P. 1-9).

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.
LRS2675WRS0139
