PRECAUTIONS ON SEAT BELT
USAGE
If you are wearing your seat belt properly
adjusted and you are sitting upright and
well back in your seat with both feet on the
floor, your chances of being injured or killed
in a collision and/or the severity of injury
may be greatly reduced. NISSAN strongly
encourages you and all of your passengers
to buckle up every time you drive, even if
your seating position includes a supple-
mental air bag.Most U.S. states and Canadian provinces
or territories specif y that seat belts be
worn at all times when a vehicle is being
driven.
WARNING
• Every person who drives or rides in
this vehicle should use a seat belt at
all times. Children should be in the
rear seats and in an appropriate
restraint.

WARNING
• The seat belt should be properly ad-
justed to a snug fit. Failure to do so
may reduce the effectiveness of the
entire restraint system and increase
the chance or severity of injury in an
accident. Serious injury or death can
occur if the seat belt is not worn
properly.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 in-
juries in an accident.

•Be sure the seat belt tongue is se-
curely 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 ve-
hicle than there are seat belts.
• If the seat belt warning light glows
continuously 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 rec-
ommended that you visit a NISSAN
dealer for this service.
• No changes should be made to the
seat belt system. For example, do not
modif y the seat belt, add material, or
install devices that may change the
seat belt routing or tension. Doing so
may affect the operation of the seat
belt system. Modif ying or tampering
with the seat belt system may result
in serious personal injury. •
Once seat belt pretensioner(s) have
activated, they cannot be reused and
must be replaced together with the
retractor. It is recommended that you
visit a NISSAN dealer for this service.
• All seat belt assemblies, including re-
tractors and attaching hardware,
should be inspected af ter any colli-
sion. It is recommended that you visit
a NISSAN dealer for this service.
NISSAN recommends that all seat
belt assemblies in use during a colli-
sion be replaced unless the collision
was minor and the belts show no
damage and continue to operate
properly. Seat belt assemblies not in
use during a collision should also be
inspected and replaced if either
damage or improper operation is
noted.
• All child restraints and attaching
hardware should be inspected af ter
any collision. Always follow the re-
straint manufacturer's inspection in-
structions and replacement recom-
mendations. 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 re-
minder function. If your vehicle is equipped
with an enhanced seat belt reminder func-
tion, a visual and audible alert will operate if
a driver or front passenger seat belt is un-
buckled at speeds of approximately 9 mph
(15 km/h) or more under the following con-
ditions:
• If the driver seat belt is not fastened.
LRS0786
1-14Safety-Seats, seat belts and supplemental restraint system

• The front passenger’s seat belt is not fas-tened and the seat is occupied by a
passenger.
• The front passenger’s seat belt is not fas- tened and objects or external force on
the passenger seat change the seat belt
reminder classification to Occupied.
The seat belt warning light will flash under
the conditions shown above until the nec-
essary seat belt is securely fastened.
A warning chime will sound for approxi-
mately 90 seconds or until one of the fol-
lowing 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 oc-
cupant present 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 passen-
ger seat.
• An object placed between the seat cush- ion 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.
PREGNANT WOMEN
NISSAN 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
recommendations.
INJURED PERSONS
NISSAN recommends that injured persons
use seat belts. Check with your doctor for
specific recommendations.
THREE-POINT TYPE SEAT BELT
WITH RETRACTOR
WARNING
• Every person who drives or rides in
this vehicle should use a seat belt at
all times. Children should be in the
rear seats and in an appropriate
restraint.
• Do not ride in a moving vehicle when
the seatback is reclined. This can be
dangerous. The shoulder belt will not
be against your body. In an accident,
you could be thrown into it and re-
ceive neck or other serious injuries.
You could also slide under the lap belt
and receive serious internal injuries.
• For the most effective protection
when the vehicle is in motion, the
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.
Safety-Seats, seat belts and supplemental restraint system1-15

•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 se-
riously 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 cannot be un-
buckled 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.
Fastening the seat belts
1. Adjust the seat. For additional informa- tion, see “Seats” (P. 1-2).

2. Slowly pull the seat belt out of the retrac-tor and insert the tongue into the buckle
OAuntil you hear and feel the latch
engage.
• The retractor is designed to lock
during a sudden stop or on impact. A
slow pulling motion permits the
seat 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.

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 ex-
tend 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 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 re-
turns to the ELR mode af ter the seat belt
fully retracts. For additional information,
see “Child restraints” (P. 1-23).
The ALR mode should be used only for
child restraint installation. During nor-
mal seat belt use by an occupant, the ALR
mode should not be activated. If it is ac-
tivated, it may cause uncomfortable seat
belt tension. It can also change the op-
eration of the front passenger air bag.
For additional information, see “Front
passenger air bag and status light”
(P. 1-57).
WARNING
When fastening the seat belts, be cer-
tain that the seatbacks are completely
secured in the latched position. If they
are not completely secured, passen-
gers 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 automati-
cally 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 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 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 a NISSAN dealer 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. 1-12). To adjust, pull out
the adjustment button
O1and move the
shoulder belt anchor to the desired posi-
tion
O2, so the belt passes over the center
of the shoulder. The belt should be away
from your face and neck, but not falling off
your shoulder. Release the adjustment but-
ton to lock the shoulder belt anchor into
position.
WRS0139LRS0242
Safety-Seats, seat belts and supplemental restraint system1-19

WARNING
• Af ter 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 re-
duce 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 for purchase. 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 that you visit a NISSAN
dealer for assistance with purchasing an
extender if an extender is required.
WARNING
• Only NISSAN seat belt extenders,
made by the same company which
made the original equipment seat
belts, should be used with NISSAN
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 in-
stall child restraints. If the child re-
straint 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 rec-
ommended 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 completely dry.
• If dirt builds up in the shoulder belt
guide of the seat belt anchors, the seat
belts may retract slowly. Wipe the shoul-
der 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 dam-
age on the webbing is found, the entire
seat belt assembly should be replaced.
