• 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
inflates the air bags as needed. Fail-
ure to properly wear seat belts can
increase the risk or severity of injury
in an accident.
• The front passenger seat is equipped
with an occupant classification sen-
sor (pressure sensor) that turns the
front passenger air bag OFF under
some conditions. This sensor is only
used in this seat. Failure to be prop-
erly seated and wearing the seat belt
can increase the risk or severity of
injury in an accident. For additional
information, refer to “Front passen-
ger 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.

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, occupant classifica-
tion sensor (pressure sensor) and passen-
ger seat belt tension sensor. Inflator opera-
tion 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 infor-
mation 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. 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 (if the seat is
unoccupied, the light will not be illumi-
nated, but the air bag will be off ). For addi-
tional information, refer to “Front passen-
ger air bag and status light” in this 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.

Front passenger air bag
The front passenger air bag is designed to
automatically turn OFF when the vehicle is
operated under some conditions as de-
scribed below in accordance with U.S. regu-
lations. 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, such as children, by requir-
ing the air bag to be automatically turned
OFF. Certain sensors are used to meet the
requirements.
One sensor used is the occupant classifi-
cation sensor (pressure sensor). It is in the
bottom of the front passenger seat cush-
ion and is designed to detect an occupant
and objects on the seat by weight. It works
together with seat belt sensors described
in this section. For example, if a child is in
the front passenger seat, the NISSAN Ad-
vanced Air Bag System is designed to turn
the front passenger air bag OFF in accor-
dance 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 causethe air bag to turn OFF. Occupant classifi-
cation sensor operation can vary depend-
ing on the front passenger seat belt sen-
sors.
The front passenger seat belt sensors are
designed to detect if the seat belt is buck-
led and the amount of tension on the seat
belt, such as when it is in the Automatic
Locking Retractor (ALR) mode (child re-
straint mode). Based on the weight on the
seat detected by the occupant classifica-
tion sensor and the belt tension detected
on the seat belt, the NISSAN Advanced Air
Bag System determines whether the front
passenger 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 outlined in this manual should not
cause the front passenger air bag to be
automatically turned OFF. For small adults
it may be turned OFF, however, if the occu-
pant does not sit in the seat properly (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 ALR 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
children be properly restrained in a rear
seat. NISSAN also recommends that ap-
propriate child restraints and booster
seats be properly installed in a rear seat. If
this is not possible, the occupant classifica-
tion sensor and seat belt sensors are de-
signed 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 ALR mode may
allow the restraint to tip or move in a colli-
sion or sudden stop. This can also result in
the passenger air bag inflating in a crash
instead of being OFF. For additional infor-
mation, refer to “Child restraints” in this sec-
tion.
If the front passenger seat is not occupied,
the front 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 de-
tected by the occupant classification sen-
sor. 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

•Tampering with the front air bag sys-
tem may result in serious personal
injury. Tampering includes changes
to the steering wheel and the instru-
ment panel assembly by placing ma-
terial over the steering wheel pad
and above the instrument panel or
by installing additional trim material
around the air bag system.
• Modif ying or tampering with the
front passenger seat may result in
serious personal injury. For example,
do not change the front seats by
placing material on the seat cushion
or by installing additional trim mate-
rial, such as seat covers, on the seat
that are not specifically designed to
assure proper air bag operation. Ad-
ditionally, do not stow any objects
under the front passenger seat or the
seat cushion and seatback. Such ob-
jects may interfere with the proper
operation of the occupant classifica-
tion sensor (pressure sensor).
• No unauthorized changes should be
made to any components or wiring
of the seat belt system. This may af-
fect the front air bag system. Tam-
pering with the seat belt system may
result in serious personal injury. •
It is recommended that you visit a
NISSAN dealer for work on and
around the front air bag. It is also rec-
ommended that you visit a NISSAN
dealer for installation of electrical
equipment. The Supplemental Re-
straint System (SRS) wiring har-
nesses* should not be modified or
disconnected. Unauthorized electri-
cal test equipment and probing de-
vices should not be used on the air
bag system.
• A 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.
*The SRS wiring harness connectors are
yellow and orange for easy identifica-
tion.
When selling your vehicle, we request that
you inform the buyer about the front air
bag system and guide the buyer to the
appropriate sections in this Owner's
Manual.
