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. 1-12).
• 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
being injured is increased.
CAUTION
When adjusting the seat positions, be sure
not to contact any moving parts to avoid
possible injuries and/or damage.

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
adjusted properly as they may provide
significant 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
removed for any reason, they should be
securely stored to prevent them from
causing 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, pas-
sengers may be injured in an accident or
sudden 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 completely
backwards. For additional information, see
“Forward and backward” (P. 1-5).
3.Make sure that the head restraints/
headrests are lowered. For additional infor-
mation, see “Lower” (P. 1-11).

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 or chime continues while the
ignition is turned on with all doors closed
and all seat belts fastened, it may indi-
cate 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
routing or tension. Doing so may affect
the operation of the seat belt system.
Modifying or tampering with the seat
belt system may result in serious per-
sonal injury. •
Once the seat belt pretensioner(s) have
activated, they cannot be reused and
must be replaced together with the re-
tractor. 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
collision. Always follow the restraint
manufacturer'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 parked.
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 may be equipped with a seat
belt reminder in the vehicle information
display.
The rear seat belt icons will illuminate when
not fastened. When a rear passenger's seat
belt has been securely fastened, the color of
the corresponding seat belt icon will change.
For additional information, see “Vehicle in-
formation display” (P. 2-19).
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.
Contact your doctor for specific recommen-
dations.
