•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.

• 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.

PRECAUTIONS ON SRS
This SRS section contains important infor-
mation concerning the following systems:
• Driver and front passenger supplementalfront-impact air bag (NISSAN Advanced
Air Bag System)
• Front seat-mounted side-impact supple- mental air bag
• Rear outboard seat-mounted side- impact supplemental air bag
• Roof-mounted curtain side-impact and rollover supplemental air bag
• Driver and front passenger supplemental knee air bag
• Seat belt with pretensioner(s) (front and rear outboard seats)
Supplemental front-impact air bag
system
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
impacted.
Rear outboard seat-mounted side-
impact supplemental air bag system
This system can help cushion the impact
force to the chest area of the rear outboard
seat passengers in certain side-impact
collisions. The side air bags are designed to
inflate on the side where the vehicle is
impacted.
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.Driver and front passenger supplemen-
tal 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 to
supplementthe
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, see “Seat belts” (P. 1-12).
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)
Safety-Seats, seat belts and supplemental restraint system1-47

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
front passenger supplemental knee air
bag may be automatically turned off under
some conditions, depending on the weight
detected on the front passenger seat and
how the seat belt is used. If the front pas-
senger air bag and front passenger
supplemental knee air bag are OFF, the
front passenger air bag status light will be
illuminated. For additional information, see
“Front passenger air bag and status light”
(P. 1-57). 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
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.
1-56Safety-Seats, seat belts and supplemental restraint system

Front passenger air bag and status
light
WARNING
The front passenger air bag and front
passenger supplemental knee air bag
are designed to automatically turn OFF
under some conditions. Read this sec-
tion carefully to learn how it operates.
Proper use of the seat, seat belt, and
child restraints is necessary for most
effective protection. Failure to follow all
instructions in this manual concerning
the use of seats, seat belts, and child
restraints can increase the risk or se-
verity of injury 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 front passenger supplemental
knee air bag on or off depending on the
weight applied to the front passenger seat.
The status of the front passenger air bag
and front passengers supplemental knee
air bag (ON or OFF) is indicated by the front
passenger air bag status light
which
is located on the instrument 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 FRONT PASSENGER
SUPPLEMENTAL 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, see “Normal op-
eration” (P. 1-59) and “Troubleshooting”
(P. 1-60).

inflate in higher severity side collisions, al-
though they may inflate if the forces in an-
other type of collision are similar to those of
a higher severity impact. They are de-
signed to inflate on the side where the ve-
hicle is impacted. They may not inflate in
certain side collisions.
Curtain air bags are also designed to inflate
in certain types of rollover collisions or near
rollovers. As a result, certain vehicle move-
ments (for example, during severe off-
roading) may cause the curtain air bags to
inflate.
Vehicle damage (or lack of it) is not always
an indication of proper side air bag and
curtain air bag operation.
When the side air bags and curtain air bags
inflate, a fairly loud noise may be heard,
followed by the release of smoke. This
smoke is not harmful and does not indi-
cate a fire. Care should be taken not to
inhale it, as it may cause irritation and
choking. Those with a history of a breath-
ing condition should get fresh air promptly.
Side air bags, along with the use of seat
belts, help to cushion the impact force on
the chest and pelvic area of the front and
rear outboard occupants. Curtain air bags
help to cushion the impact force to thehead of occupants in the front and rear
outboard seating positions. They can help
save lives and reduce serious injuries. How-
ever, an inflating side air bag and curtain air
bag may cause abrasions or other injuries.
Side air bags and curtain air bags do not
provide restraint to the lower body.
The seat belts should be correctly worn
and the driver, front passenger and rear
outboard occupants seated upright as far
as practical away from the side air bag.
Rear seat passengers should be seated as
far away as practical from the door finish-
ers and side roof rails. The side air bags and
curtain air bags inflate quickly in order to
help protect the occupants. Because of
this, the force of the side air bag and curtain
air bag inflating can increase the risk of
injury if the occupant is too close to, or is
against, these air bag modules during in-
flation. The side air bag will deflate quickly
af ter the collision is over.
The curtain air bag will remain inflated for a
short time.
The side air bags and curtain 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
• Do not place any objects near the
seatback of the front and rear seats.
Also, do not place any objects (an
umbrella, bag, etc.) between the front
and rear door finisher and the front
and rear seat. Such objects may be-
come dangerous projectiles and
cause injury if a side air bag inflate.
• Right af ter inflation, several side air
bag and curtain air bag system com-
ponents will be hot. Do not touch
them; you may severely burn
yourself.
• No unauthorized changes should be
made to any components or wiring
of the side air bag and curtain air bag
systems. This is to prevent damage
to or accidental inflation of the side
air bag and curtain air bag or dam-
age to the side air bag and curtain air
bag systems.
Safety-Seats, seat belts and supplemental restraint system1-63

Vehicle damage (or lack of it) is not always
an indication of proper knee air bag
operation.
When the knee air bag inflates, a fairly loud
noise may be heard, followed by release of
smoke. This smoke is not harmful and
does not indicate a fire. Care should be
taken not to inhale it, as it may cause irrita-
tion and choking. Those with a history of a
breathing condition should get fresh air
promptly.The knee air bag helps to cushion the im-
pact force on the knees of the driver and
passenger. It can help reduce serious inju-
ries. However, an inflating knee air bag may
cause abrasions or other injuries. The knee
air bag provides restraint to the lower body.
The knee air bag inflates quickly in order to
help protect the occupants. Because of
this, the force of the knee air bag inflating
can increase the risk of injury if the occu-
pant is too close to, or is against, this air bag
module during inflation. The knee air bag
will deflate quickly af ter the collision is over
OR the knee air bag will remain inflated for
a short time.
The knee air bag operates 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
• Do not place any objects between the
knee bolster and the driver’s or pas-
senger’s seat. Such objects may be-
come dangerous projectiles and
cause injury if a knee air bag inflates.
• Right af ter inflation, the knee air bag
system components will be hot. Do
not touch them; you may severely
burn yourself.
• No unauthorized changes should be
made to any components or wiring
of the knee air bag system. This is to
prevent damage to or accidental in-
flation of the knee air bag system.
• Do not make unauthorized changes
to your vehicle's electrical system or
suspension system. This could affect
proper operation of the knee air bag
system.
• Tampering with the knee air bag sys-
tem may result in serious personal
injury. For example, do not change
the driver or passenger knee bolster
or install additional trim material
around the knee air bag.
