∙ 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.
SEAT BELT WARNING LIGHT
Both the driver’s and passenger’s front
seats are equipped with a seat belt warn-
ing light. The warning light, located on the
instrument panel, will show the status of
the driver and passenger seat belt.
NOTE:
The front passenger seat belt warning
light will not light up if the seat is not
occupied.

For additional information, refer to “Warn-
ing lights, indicator lights and audible re-
minders” in the “Instruments and controls”
section of this manual.
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
WITH RETRACTOR
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. ∙ Do not allow children to play with the
seat belts. Most seating positions are
equipped with Automatic Locking Re-
tractor (ALR) mode seat belts. If the
seat belt becomes wrapped around a
child’s neck with the ALR mode acti-
vated, the child can be seriously in-
jured 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 unbuckled or is
already unbuckled, release the child
by cutting the seat belt with a suitable
tool (such as a knife or scissors) to
release the seat belt.

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 (if so equipped) is
removed, store it in a secure place. Be
sure to reinstall the head
restraint/headrest (if so equipped)
when the child restraint is removed.

7. If the booster seat is installed in thefront passenger seat, place the ignition
switch in the ON position. The front pas-
senger 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 infor-
mation, refer to “Front passenger air
bag and status light” in this section.
PRECAUTIONS ON SRS
This SRS section contains important infor-
mation concerning the following systems:
∙ Driver and front passenger supplemen- tal front-impact air bag (NISSAN Ad-
vanced Air Bag System)
∙ Front seat-mounted side-impact supplemental air bag
∙ Roof-mounted curtain side-impact and rollover supplemental air bag
∙ Seat belt with pretensioner(s) (front seats)
Supplemental front-impact air bag sys-
tem
The NISSAN Advanced Air Bag System can
help cushion the impact force to the head
and chest of the driver and front passenger
in certain frontal collisions.
Front seat-mounted side-impact
supplemental air bag system
This system can help cushion the impact
force to the chest area of the driver and
front passenger in certain side-impact col-
lisions. The side air bags are designed to
inflate on the side where the vehicle is im-
pacted. Roof-mounted curtain side-impact and
rollover supplemental air bag system
This system can help cushion the impact
force to the head of occupants in front and
rear outboard seating positions in certain
side-impact collisions. The curtain air bags
are designed to inflate on the side where
the vehicle is impacted. In a rollover, the
curtain air bags are designed to inflate and
remain inflated for a short time.
The SRS is designed to
supplementthe
crash protection provided by the driver and
front passenger seat belts and is not a
substitute for them. Seat belts should al-
ways be correctly worn and the occupant
seated a suitable distance away from the
steering wheel, instrument panel and door
finishers. For additional information, 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.

SUPPLEMENTAL RESTRAINT SYSTEM
(SRS)
1-44Safety—Seats, seat belts and supplemental restraint system

WARNING
∙ The front air bags ordinarily will notinflate 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 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. ∙ The seat belts and the front air bags
are most effective when you are sit-
ting well back and upright in the seat.
The front air bags inflate with great
force. Even with the NISSAN Advanced
Air Bag System, if you are unre-
strained, leaning forward, sitting side-
ways or out of position in any way, you
are at greater risk of injury or death in
a crash. You may also receive serious
or fatal injuries from the front air bag
if you are up against it when it inflates.
Always sit back against the seatback and as far away as practical from the
steering wheel or instrument panel.
Always properly use the seat belts.
∙ The driver and front passenger seat belt buckles are equipped with sen-
sors that detect if the seat belts are
fastened. The NISSAN Advanced Air
Bag System monitors the severity of a
collision and seat belt usage, then in-
flates the air bags as needed. Failure
to properly wear seat belts can in-
crease the risk or severity of injury in
an accident.
∙ The front passenger seat is equipped with an occupant classification sen-
sor (weight sensor) that turns the
front passenger air bag OFF under
some conditions. This sensor is only
used in this seat. Failure to be properly
seated and wearing the seat belt can
increase the risk or severity of injury in
an accident. For additional informa-
tion, refer to “Front passenger air bag
and status light” in this section.
∙ Keep hands on the outside of the steering wheel. Placing them inside
the steering wheel rim could increase
the risk that they are injured when the
front air bag inflates.

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
may deploy in a collision. Also the
front passenger air bag status light
may not illuminate. For additional in-
formation about installing and using
child restraints, refer to "Child re-
straints" 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.
Safety—Seats, seat belts and supplemental restraint system1-51

∙ Do not position the front passengerseat 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
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 may be
automatically turned off under some con-
ditions, depending on the weight detected
on the front passenger seat and how the
seat belt is used. If the front passenger air
bag is OFF, the front passenger air bag sta-
tus light will be illuminated. For additional
information, refer to “Front passenger air
bag and status light” in this section. One
front air bag inflating does not indicate im-
proper 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 informationabout 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-
