•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. Fail-
ure to be properly seated and wear-
ing 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. 1-54).
• 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 rear
bench seats 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 or in the seatback
pocket.
• 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 front passenger supple-
mental knee air bag may deploy in a
collision. Also the front passenger air
bag status light may not illuminate.
For additional information, see “Child
restraints” (P. 1-22).
• 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
occupant 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 sta-
tus 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. 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 dash-
board 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 inflate in certain fron-
tal collisions. Vehicle damage (or lack of it) is
not always an indication of proper front air
bag system operation.
1-52Safety-Seats, seat belts and supplemental restraint system

The NISSAN Advanced Air Bag System moni-
tors information from the crash zone sensor,
the Air bag Control Unit (ACU), seat belt
buckle sensors and occupation classifica-
tion sensor (weight sensor). Inflator opera-
tion is based on the severity of a collision and
seat belt usage for the driver. For the front
passenger, the occupant classification sen-
sor 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. Additionally, the front
passenger air bag and front passenger
supplemental knee air bag may be auto-
matically 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 front passenger air bag status
light will be illuminated. For additional infor-
mation, see “Front passenger air bag and
status light” (P. 1-54). One front air bag inflat-
ing 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 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.

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 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 op-
eration” (P. 1-56) and “Troubleshooting”
(P. 1-57).
