NISSAN Advanced Air Bag System
(front seats)
This vehicle is equipped with the NISSAN ad-
vanced air bag system for the driver and front
passenger seats. This system is designed to
meet certification requirements under U.S. regu-
lations. It is also permitted in Canada.However,
all of the information, cautions and warn-
ings in this manual still apply and must be
followed.

The driver supplemental front air bag is located in
the center of the steering wheel. The passenger
supplemental front air bag is mounted in the
dashboard above the glove box. The supplemen-
tal front air bags are designed to inflate in higher
severity frontal collisions, although they may in-
flate if the forces in another type of collision are
similar to those of a higher severity frontal impact.
They may not inflate in certain frontal collisions.
Vehicle damage (or lack of it) is not always an
indication of proper supplemental front air bag
system operation.
The NISSAN advanced air bag system has dual
stage inflators. It also monitors information from
the crash zone sensor, the diagnosis sensor unit,
seat belt buckle sensors, occupant classification
sensor (pressure sensor) and passenger seat
belt tension sensor. Inflator operation is based on
the severity of a collision and seat belt usage for
the driver. For the front passenger, it additionally
monitors the weight of an occupant or object on
the seat and seat belt tension. Based on informa-
tion from the sensors, only one front air bag may
inflate in a crash, depending on the crash severity
and whether the front occupants are belted or
unbelted. Additionally, the front passenger air
bag may be automatically turned OFF under
some conditions, depending on the weight de-
tected on the passenger seat and how the seat
belt is used. If the front passenger air bag is OFF,the passenger air bag status light will be illumi-
nated (if the seat is unoccupied, the light will not
be illuminated, but the air bag will be off) . See
“Front passenger air bag and status light” later in
this section for further details. One front air bag
inflating does not indicate improper performance
of the system.
If you have any questions about your air bag
system, please contact NISSAN or your NISSAN
dealer. If you are considering modification of your
vehicle due to a disability, you may also contact
NISSAN. Contact information is contained in the
front of this Owner’s Manual.
When a supplemental front air bag inflates, a
fairly loud noise may be heard, followed by the
release 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 irritation and chok-
ing. Those with a history of a breathing condition
should get fresh air promptly.
Supplemental 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 serious injuries.
However, an inflating front air bag may cause
facial abrasions or other injuries. Front air bags
do not provide restraint to the lower body.
Even with NISSAN advanced air bags, seat belts
should be correctly worn and the driver and pas-senger seated upright as far as practical away
from the steering wheel or instrument panel. The
supplemental 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
increase 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 after a collision.
The supplemental front air bags operate
only when the ignition switch is in the ON
or START position.
After turning the ignition key to the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7
seconds if the system is operational.

Front passenger air bag and status light
WARNING
The front passenger air bag is designed to
automatically turn OFF under some con-
ditions. Read this section carefully to
learn how it operates. Proper use of the
seat, seat belt and child restraints is nec-
essary for most effective protection. Fail-
ure to follow all instructions in this
manual concerning the use of seats, seat
belts and child restraints can increase the
risk or severity of injury in an accident.Status light
The front passenger air bag status light
is
located near the climate controls. The light oper-
ates as follows:
cUnoccupied passenger’s seat: The
is
OFF and the front passenger air bag is OFF
and will not inflate in a crash.
cPassenger’s seat occupied by a small adult,
child or child restraint as outlined in this
section: The
illuminates to indicate
that the front passenger air bag is OFF and
will not inflate in a crash.
cOccupied passenger seat and the passen-
ger meet the conditions outlined in this sec-
tion: The light
is OFF to indicate that
the front passenger air bag is operational.
Front passenger air bag
The front passenger air bag is designed to auto-
matically turn OFF when the vehicle is operated
under some conditions as described below in
accordance with U.S. regulations. If the front
passenger air bag is OFF, it will not inflate in a
crash. The driver air bag and other air bags in your
vehicle are not part of this system.
The purpose of the regulation is to help reduce
the risk of injury or death from an inflating air bag
to certain front passenger seat occupants, suchas children, by requiring the air bag to be auto-
matically turned OFF. Certain sensors are used
to meet the requirements.
One sensor used is the occupant classification
sensor (pressure sensor) . It is in the bottom of the
front passenger seat cushion and is designed to
detect an occupant and objects on the seat by
weight. It works together with seat belt sensors
described later. For example, if a child is in the
front passenger seat, the advanced air bag sys-
tem is designed to turn the passenger air bag
OFF in accordance with the regulations. Also, if a
child restraint of the type specified in the regula-
tions is on the seat, its weight and the child’s
weight can be detected and cause the air bag to
turn OFF. Occupant classification sensor opera-
tion can vary depending on the front passenger
seat belt sensors.
The front passenger seat belt sensors are de-
signed to detect if the seat belt is buckled and the
amount of tension on the seat belt, such as when
it is in the automatic locking mode (child restraint
mode) . Based on the weight on the seat detected
by the occupant classification sensor and the belt
tension detected on the seat belt, the advanced
air bag system determines whether the front pas-
senger air bag should be automatically turned
OFF as required by the regulations.

Front passenger seat adult occupants who are
properly seated and using the seat belt as out-
lined in this manual should not cause the passen-
ger air bag to be automatically turned OFF. For
small adults it may be turned OFF, however if the
occupant takes his/her weight off the seat cush-
ion (for example, by not sitting upright, by sitting
on an edge of the seat, or by otherwise being out
of position) , this could cause the sensor to turn
the air bag OFF. In addition, if the occupant
improperly uses the seat belt in the automatic
locking mode (child restraint mode) , this could
cause the air bag to be turned OFF. Always be
sure to be seated and wearing the seat belt
properly for the most effective protection by the
seat belt and supplemental air bag.
NISSAN recommends that pre-teens and chil-
dren be properly restrained in a rear seat.
NISSAN also recommends that appropriate child
restraints and booster seats be properly installed
in a rear seat. If this is not possible, the occupant
classification sensor and seat belt sensors are
designed to operate as described above to turn
the front passenger air bag OFF for specified
child restraints as required by the regulations.
Failing to properly secure child restraints and to
use the automatic locking mode (child restraint
mode) may allow the restraint to tip or move in an
accident or sudden stop. This can also result in
the passenger air bag inflating in a crash insteadof being OFF. See “Child restraints” earlier in this
section for proper use and installation.
If the front passenger seat is not occupied the
passenger air bag is designed not to inflate in a
crash. However, heavy objects placed on the
seat could result in air bag inflation, because of
the object’s weight detected by the occupant
classification sensor. Other conditions could also
result in air bag inflation, such as if a child is
standing on the seat, or if two children are on the
seat, contrary to the instructions in this manual.
Always be sure that you and all vehicle occupants
are seated and restrained properly.
Using the passenger air bag status light, you can
monitor when the front passenger air bag is au-
tomatically turned OFF with the seat occupied.
The light will not illuminate when the front pas-
senger seat is unoccupied.
If an adult occupant is in the seat but the passen-
ger air bag status light is illuminated (indicating
that the air bag is OFF) , it could be that the
person is a small adult, or is not sitting on the seat
properly or not using the seat belt properly.
If a child restraint must be used in the front seat,
the passenger air bag status light may or may not
be illuminated, depending on the size of the child
and the type of child restraint being used. If the
passenger air bag status light is not illuminated
(indicating that the air bag might inflate in acrash) , it could be that the child restraint or seat
belt is not being used properly. In rare cases, the
passenger air bag status light will not illuminate
even though the air bag is OFF.
If such situations happen, properly position and
restrain the occupant or child restraint. Other-
wise reposition the occupant or child restraint in
a rear seat. If you have any questions about
whether your passenger air bag is working as
designed, your NISSAN dealer can confirm that it
is working properly by using a special tool.
The air bag system and passenger air bag status
light will take a few seconds to register a change
in the passenger seat status. For example, if a
large adult who is sitting in the front passenger
seat exits the vehicle, the passenger air bag
status light will go from OFF to ON for a few
seconds and then to OFF. This is normal system
operation and does not indicate a malfunction.
If a malfunction occurs in the front passenger air
bag system, the supplemental air bag warning
light
, located in the meter and gauges area
in the center of the instrument panel, will blink.
Have the system checked by a NISSAN dealer.

Other supplemental front air bag precau-
tions
WARNING
cDo not place any objects on the steer-
ing wheel pad or on the instrument
panel. Also, do not place any objects
between any occupant and the steering
wheel or instrument panel. Such ob-
jects may become dangerous projec-
tiles and cause injury if the supplemen-
tal front air bag inflates.
cImmediately after inflation, several
front air bag system components will be
hot. Do not touch them; you may se-
verely burn yourself.
cNo unauthorized changes should be
made to any components or wiring of
the supplemental air bag system. This is
to prevent accidental inflation of the
supplemental air bag or damage to the
supplemental air bag system.
cDo not make unauthorized changes to
your vehicle’s electrical system, sus-
pension system or front end structure.
This could affect proper operation of
the supplemental front air bag system.cTampering with the supplemental front
air bag system may result in serious
personal injury. Tampering includes
changes to the steering wheel and the
instrument panel assembly by placing
material over the steering wheel pad
and above the instrument panel or by
installing additional trim material
around the air bag system.
cModifying or tampering with the front
passenger seat may result in serious
personal injury. For example, do not
change the front seats by placing mate-
rial on the seat cushion or by installing
additional trim material, such as seat
covers, on the seat that are not specifi-
cally designed to assure proper air bag
operation. Additionally, do not stow any
objects under the front passenger seat
or the seat cushion and seatback. Such
objects may interfere with the proper
operation of the occupant classifica-
tion sensor (pressure sensor) .
cNo unauthorized changes should be
made to any components or wiring of
the seat belt system. This may affect the
supplemental front air bag system.
Tampering with the seat belt system
may result in serious personal injury.cWork on and around the supplemental
front air bag system should be done by
a NISSAN dealer. Installation of electri-
cal equipment should also be done by a
NISSAN dealer. The Supplemental Re-
straint System (SRS) wiring should not
be modified or disconnected. Unautho-
rized electrical test equipment and
probing devices should not be used on
the air bag system.
cA cracked windshield should be re-
placed immediately by a qualified re-
pair facility. A cracked windshield could
affect the function of the supplemental
air bag system.
cThe SRS wiring harness connectors are
yellow and orange for easy
identification.
When selling your vehicle, we request that you
inform the buyer about the supplemental front air
bag system and guide the buyer to the appropri-
ate sections in this Owner’s Manual.

Supplemental side-impact air bag and
curtain side-impact and rollover air
bags system (if so equipped)
The supplemental side-impact air bags are lo-
cated in the outside of the seatback of the front
seats. The supplemental curtain side-impact and
rollover air bags are located in the side roof rails.
These systems are designed to meet voluntary
guidelines to help reduce the risk of injury to
out-of-position occupants.However, all of the
information, cautions and warnings in this
manual still apply and must be followed.
The supplemental side air bags and curtain side-
impact and rollover air bags are designed toinflate in higher severity side collisions, although
they may inflate if the forces in another type of
collision are similar to those of a higher severity
side impact. They are designed to inflate on the
side where the vehicle is impacted. They may not
inflate in certain side collisions.
Curtain side-impact and rollover air bags are also
designed to inflate in certain types of rollover
collisions or near rollovers.
Vehicle damage (or lack of it) is not always an
indication of proper supplemental side air bag
and curtain side-impact and rollover air bag op-
eration.
When the supplemental side air bag and curtain
air bags inflate, 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 irritation
and choking. Those with a history of a breathing
condition should get fresh air promptly.
Supplemental side air bags, along with the use of
seat belts, help to cushion the impact force on
the chest of the front occupants. Curtain side-
impact and rollover air bags help to cushion the
impact force to the head 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, or curtain air bag
may cause abrasions or other injuries. Supple-mental side air bags and curtain side-impact and
rollover air bags do not provide restraint to the
lower body.
The seat belts should be correctly worn and the
driver and passenger seated upright as far as
practical away from the supplemental side air
bag. Rear seat passengers should be seated as
far away as practical from the door finishers and
side roof rails. The side air bags and curtain
side-impact and rollover air bag 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 inflation. The side air bag will
deflate quickly after the collision is over.
The curtain side-impact and rollover air bag will
remain inflated for a short time.
The supplemental side air bags and curtain
side-impact and rollover air bags operate
only when the ignition switch is in the ON
or START positions.
After turning the ignition key to the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7
seconds if the system is operational.

WARNING
cDo not place any objects near the seat-
back of the front seats. Also, do not
place any objects (an umbrella, bag,
etc.) between the front door finisher
and the front seat. Such objects may
become dangerous projectiles and
cause injury if the supplemental side air
bag inflates.
cRight after inflation, several side air bag
and curtain side-impact and rollover air
bag system components will be hot. Do
not touch them; you may severely burn
yourself.
cNo unauthorized changes should be
made to any components or wiring of
the side air bag and curtain air bag
system. This is to prevent accidental
inflation of the side air bag and curtain
air bag or damage to the side air bag
and curtain air bag system.
cDo not make unauthorized changes to
your vehicle’s electrical system, sus-
pension system or side panel. This
could affect proper operation of the
supplemental curtain air bag system.cTampering with the supplemental side
air bag system may result in serious
personal injury. For example, do not
change the front seats by placing mate-
rial near the seatbacks or by installing
additional trim material, such as seat
covers, around the side air bag.
cWork around and on the curtain air bag
system should be done by a NISSAN
dealer. Installation of electrical equip-
ment should also be done by a NISSAN
dealer. The SRS wiring harnesses*
should not be modified or discon-
nected. Unauthorized electrical test
equipment and probing devices should
not be used on the side air bag or cur-
tain air bag system.
* The SRS wiring harness or connectors are
yellow or orange for easy identification.
When selling your vehicle, we request that you
inform the buyer about the supplemental side air
bag and curtain air bag system and guide the
buyer to the appropriate sections in this Owner’s
Manual.
Pre-tensioner seat belt system (Front
seats)
WARNING
cThe pre-tensioner seat belt cannot be
reused after activation. It must be re-
placed together with the retractor and

cWork around and on the pre-tensioner
system should be done by a NISSAN
dealer. Installation of electrical equip-
ment should also be done by a NISSAN
dealer. Unauthorized electrical test
equipment and probing devices should
not be used on the pre-tensioner seat
belt system.
cIf you need to dispose of the pre-
tensioner or scrap the vehicle, contact a
NISSAN dealer. Correct pre-tensioner
disposal procedures are set forth in the
appropriate NISSAN Service Manual.
Incorrect disposal procedures could
cause personal injury.
The front seat pre-tensioner seat belt system
activates in conjunction with the front supple-
mental air bag systems. Working with the seat
belt retractor, it helps tighten the seat belt when
the vehicle becomes involved in certain types of
collisions, helping to restrain front seat occu-
pants.
The pre-tensioner is encased with the seat belt’s
retractor. These seat belts are used the same as
conventional seat belts.When the pre-tensioner seat belt activates,
smoke is released and a loud noise may be heard.
This smoke is not harmful and does not indicate a
fire. Care should be taken not to inhale it, as it may
cause irritation and choking. Those with a history
of a breathing condition should get fresh air
promptly.
After the pre-tensioner seat belts have activated,
load limiters allow the seat belt to release web-
bing (if necessary) to reduce forces against the
chest.
If any abnormality occurs in the pre-tensioner
system, the supplemental air bag warning
light
will not come on, will flash intermit-
tently or will turn on for 7 seconds and remain on
after the ignition key has been turned to the ON or
START position. In this case, the pre-tensioner
seat belt may not function properly. They must be
checked and repaired. Take your vehicle to the
nearest NISSAN dealer.
When selling your vehicle, we request that you
inform the buyer about the pre-tensioner seat belt
system and guide the buyer to the appropriate
sections in this Owner’s Manual.1. SRS Air bag warning labels
The warning labels are located on the sur-
face of the sun visor.
