•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 Ad-
vanced Air Bag System, if you are un-
restrained, leaning forward, sitting
sideways or out of position in any
way, you are at greater risk of injury
or death in a crash. You may also re-
ceive 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
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 (weight sensor) that turns the
front passenger air bag and front
passenger supplemental knee 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 information,
see “Front passenger air bag and
status light” (P. 1-55).
• 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
passenger’s NISSAN Advanced Air bag
System, please observe the following
items.
• Do not allow a passenger in the rear
seat to push or pull on the seatback
pocket (if so equipped).
• Do not place heavy loads heavier
than 9.1 lbs. (4 kg) on the seatback,
head restraint/headrest or in the
seatback pocket (if so equipped).
• Make sure that there is nothing
pressing against the rear of the seat-
back, such as a child restraint in-
stalled 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 re-
straint does contact the instrument
panel, the system may determine the
seat is occupied and the passenger
air bag and the front passenger
supplemental knee air bag may de-
ploy in a collision. Also the front pas-
senger air bag status light may not
illuminate. For additional informa-
tion, see “Child restraints” (P. 1-23).
• 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 occu-
pant 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 oc-
cupant classification system is work-
ing 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
supplemental 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. All of the information, cautions
and warnings in this manual 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
Safety-Seats, seat belts and supplemental restraint system1-53

damage (or lack of it) is not always an indi-
cation of proper front air bag system
operation.
The NISSAN Advanced Air Bag System
monitors information from the crash zone
sensor, the Air bag Control Unit (ACU). Infla-
tor operation is based on the severity of a
collision and seat belt usage for the driver.
For the front passenger, the occupant clas-
sification sensor is also monitored. Based
on information from the sensor, only one
front air bag may inflate in a crash, depend-
ing on the crash severity and whether the
front occupants are belted or unbelted. Ad-
ditionally, 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
passenger air bag and front passenger
supplemental knee air bag are OFF, the
passenger air bag status light will be illumi-
nated. For additional information, see
“Front passenger air bag and status light”
(P. 1-55). 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, other than the driv-
er’s and front passenger’s supplemental
knee 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 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.

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 passenger 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
operation” (P. 1-57) and “Troubleshooting”
(P. 1-58).

Safety-Seats, seat belts and supplemental restraint system1-55

Front passenger air bag
The front passenger air bag and front pas-
senger supplemental knee air bag are de-
signed to automatically 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
and front passenger supplemental knee
air bag are 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.
The occupant classification sensor in this
vehicle is a weight sensor. It is designed to
detect an occupant and objects on the
seat by weight. 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 and front pas-
senger supplemental knee air bag OFF in
accordance with the regulations. Also, if a
child restraint of the type specified in the
regulations is on the seat, its weight andthe child’s weight can be detected and
cause the air bag to turn OFF.
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 and
front passenger supplemental knee 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 cushion (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 front
passenger air bag and front passenger
supplemental knee air bag 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 classifi-
cation sensor is designed to operate as
described above to turn the front passen-
ger air bag and front passenger supple-
mental knee 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 collision or
sudden stop. This can also result in the
passenger air bag and front passenger
supplemental knee air bag inflating in a
crash instead of being OFF. For additional
information, see “Child restraints” (P. 1-23).
If the front passenger seat is not occupied,
the front passenger air bag and front pas-
senger supplemental knee air bag are de-
signed 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 front passenger air bag status
light, you can monitor when the front
passenger air bag and front passenger
supplemental knee air bag are automati-
cally turned OFF.
