∙ 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 vehicle 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 indicate a
malfunction in the system. Have the
system checked. It is recommended
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 collision be
replaced unless the collision was mi-
nor 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 im-
proper 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.

∙ The front passenger’s seat belt is notfastened and the seat is occupied by a
passenger for 7 seconds af ter the igni-
tion switch is placed in the ON position.
∙ The front passenger’s seat belt is not fastened and objects or external force
on the passenger seat change the seat
belt reminder classification to Occu-
pied.
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 occu-
pied.
∙ 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 pas- senger 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.
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 rec-
ommendations.
INJURED PERSONS
NISSAN recommends that injured persons
use seat belts. Check with your doctor for
specific recommendations.
THREE-POINT TYPE SEAT BELT

WARNING
∙ Every person who drives or rides inthis 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.

4. Pull the shoulder belt portion toward the retractor to take up extra slack
C.
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, re-
fer to “Child restraints” in this section.
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, refer to
“Front passenger air bag and status
light” in this section.
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, passengers
may be injured in an accident or sudden
stop.

FORWARD-FACING CHILD
RESTRAINT 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. For additional informa-
tion, refer to “Front passenger air bag
and status light” in this section.For additional information, refer to all Warn-
ings and Cautions in the “Child safety” and
“Child restraints” sections of this manual
before installing a child restraint.
Do not use the lower anchors if the com-
bined weight of the child and the child re-
straint exceeds 65 lbs. (29.5 kg). If the com-
bined 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 forward-
facing child restraint using the vehicle seat
belt in the rear seats or in the front passen-
ger 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 restraints 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 seat-
back.
If necessary, adjust or remove the head
restraint/headrest to obtain the cor-
rect 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 restraint is removed. For ad-
ditional information about head
restraint/headrest adjustment, re-
moval and installation, refer to “Head
restraints/headrests” in this section.

1-38Safety—Seats, seat belts and supplemental restraint system

Driver and passenger supplemental
knee air bags
This system can help cushion the impact
force to the driver’s and front passenger’s
knees in certain collisions.
The SRS is designed tosupplementthe
crash protection provided by the driver and
front passenger and rear seat belts and is
not a substitute for them. Seat belts
should always be correctly worn and the
occupant seated a suitable distance away
from the steering wheel, instrument panel
and door finishers. For additional informa-
tion, refer to “Seat belts” in this section.
The supplemental air bags operate only
when the ignition switch is placed in the
ON position.
Af ter placing the ignition switch in the
ON position, the supplemental air bag
warning light illuminates. The supple-
mental air bag warning light will turn off
af ter about 7 seconds if the system is
operational.
WARNING
∙ The front air bags ordinarily will not inflate in the event of a side impact,
rear impact, rollover, or lower severity
frontal collision. Always wear your
seat belts to help reduce the risk or
severity of injury in various kinds of
accidents
∙ The front passenger air bag and pas- senger knee air bag will not inflate if
the passenger air bag status light is
lit. For additional information, refer to
“Front passenger air bag and status
light” in this section.

WARNING
To ensure proper operation of the pas-
senger’s NISSAN Advanced Air Bag Sys-
tem, please observe the following
items.
∙ Do not allow a passenger in the rearseat to push or pull on the seatback
pocket.
∙ Do not place heavy loads heavier than 9.1 lbs. (4 kg) on the seatback, head
restraint/headrest or in the seatback
pocket.
∙ Make sure that there is nothing press- ing against the rear of the seatback,
such as a child restraint installed in
the rear seat or an object stored on
the floor.
∙ Make sure that there is no object placed under the front passenger
seat. ∙ Make sure that there is no object
placed between the seat cushion and
center console or between the seat
cushion and the door.
∙ If a forward facing child restraint is installed in the front passenger seat,
do not position the front passenger
seat so the child restraint contacts the
instrument panel. If the child restraint
does contact the instrument panel,
the system may determine the seat is
occupied and the passenger air bag
and passenger knee air bag may de-
ploy in a collision. Also the front pas-
senger air bag status light may not
illuminate. For additional information
about installing and using child re-
straints, refer to "Child restraints" in
this section.
∙ Confirm the operating condition with the front passenger air bag status
light.
∙ If you notice that the front passenger air bag status light is not operating as
described in this section, get the oc-
cupant classification system checked.
It is recommended that you visit a
NISSAN dealer for this service. ∙ Until you have confirmed with a
dealer that your passenger seat occu-
pant classification system is working
properly, position the occupants in
the rear seating positions.
∙ Do not position the front passenger seat so it contacts the rear seat. If the
front seat does contact the rear seat,
the air bag system may determine a
sensor malfunction has occurred and
the front passenger air bag status
light may illuminate and the supple-
mental air bag warning light may
flash.
This vehicle is equipped with the NISSAN
Advanced Air Bag System for the driver and
front passenger seats. This system is de-
signed to meet certification requirements
under U.S. regulations. It is also permitted in
Canada. However, all of the information,
cautions and warnings in this manual
still apply and must be followed.
The driver supplemental front-impact air
bag is located in the center of the steering
wheel. The front passenger supplemental
front-impact air bag is mounted in the
dashboard above the glove box. The front
air bags are designed to inflate in higher
severity frontal collisions, although they
Safety—Seats, seat belts and supplemental restraint system1-55

may inflate if the forces in another type of
collision are similar to those of a higher
severity frontal impact. They may not in-
flate in certain frontal collisions. Vehicle
damage (or lack of it) is not always an indi-
cation of proper front air bag system op-
eration.
The NISSAN Advanced Air Bag System
monitors information from the crash zone
sensor, the Air bag Control Unit (ACU), seat
belt buckle sensors and occupant classifi-
cation sensor (weight sensor). Inflator op-
eration is based on the severity of a colli-
sion and seat belt usage for the driver. For
the front passenger, the occupant classifi-
cation sensor is also monitored. Based on
information from the sensor, only one front
air bag may inflate in a crash, depending on
the crash severity and whether the front
occupants are belted or unbelted. Addi-
tionally, the front passenger air bag and
passenger knee air bag may be automati-
cally turned off under some conditions, de-
pending on the weight detected on the
front passenger seat and how the seat belt
is used. If the front passenger air bag and
passenger knee air bag are OFF, the front
passenger air bag status light will be illumi-
nated. For additional information, refer to
“Front passenger air bag and status light” inthis section. One front air bag inflating does
not indicate improper performance of the
system.
If you have any questions about your air
bag system, it is recommended that you
visit a NISSAN dealer to obtain information
about the system. If you are considering
modification of your vehicle due to a dis-
ability, you may also contact NISSAN. Con-
tact information is contained in the front of
this Owner’s Manual.
When a front air bag inflates, a fairly loud
noise may be heard, followed by the re-
lease of smoke. This smoke is not harmful
and does not indicate a fire. Care should be
taken to not inhale it, as it may cause irrita-
tion and choking. Those with a history of a
breathing condition should get fresh air
promptly.
Front air bags, along with the use of seat
belts, help to cushion the impact force on
the face and chest of the front occupants.
They can help save lives and reduce seri-
ous injuries. However, an inflating front air
bag may cause facial abrasions or other
injuries. Front air bags do not provide re-
straint to the lower body.
Even with NISSAN Advanced Air Bags, seat
belts should be correctly worn and the
driver and front passenger seated upright
as far as practical away from the steering
wheel or instrument panel. The front air
bags inflate quickly in order to help protect
the front occupants. Because of this, the
force of the front air bag inflating can in-
crease the risk of injury if the occupant is
too close to, or is against, the front air bag
module during inflation.
The front air bags deflate quickly af ter a
collision.
The front air bags operate only when the
ignition switch is placed in the ON posi-
tion.
Af ter placing the ignition switch in the
ON position, the supplemental air bag
warning light illuminates. The supple-
mental air bag warning light will turn off
af ter about 7 seconds if the system is
operational.

Front passenger air bag and status light
WARNING
The front passenger air bag and pas-
senger knee air bag are designed to au-
tomatically turn OFF under some condi-
tions. Read this section carefully to
learn how it operates. Proper use of the
seat, seat belt, and child restraints is
necessary for most effective protec-
tion. Failure to follow all instructions in
this manual concerning the use of
seats, seat belts, and child restraints
can increase the risk or severity of in-
jury in an accident.Status light
The front passenger seat is equipped with
an occupant classification sensor (weight
sensor) that turns the front passenger air
bag and passenger knee air bag on or off
depending on the weight applied to the
front passenger seat. The status of the
front passenger air bag (ON or OFF) is indi-
cated by the front passenger air bag status
light
which is located on the instru-
ment panel.
Af ter the ignition switch is placed in the
"ON" position, the front passenger air bag
status light on the instrument panel illumi-
nates for about 7 seconds and then turns
off or remains illuminated depending on
the front passenger seat occupied status.
The light operates as follows:
CONDITION DESCRIPTION PASSENGER AIR BAG
STATUS LIGHT () FRONT PASSENGER AIR BAG AND PASSENGER KNEE AIR BAG STATUS
Empty Empty front passenger seat ON (illuminated) INHIBITED
Nobody/Somebody Bag or Child or Child Restraint or
Small Adult in front passenger seat ON (illuminated)
INHIBITED
Adult Adult in the front passenger seat OFF (dark) ACTIVATED
In addition to the above, certain objects
placed on the front passenger seat may
also cause the light to operate as de-
scribed above depending on their weight.For additional information, refer to “Normal
operation” and “Troubleshooting” in this
section.
