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 front passenger air bag status
light may or may not be illuminated, de-
pending on the size of the child and the
type of child restraint being used. Always
make sure that the child restraint is in-
stalled properly, the seat belt is used prop-
erly and the occupant is positioned prop-
erly.
If necessary, a NISSAN dealer can check
system operation by using a special tool.
Until you have confirmed with a dealer that
your air bag is working properly, reposition
the occupant or child restraint in a rear
seat.
The NISSAN Advanced Air Bag System and
front passenger air bag status light will
take a few seconds to register a change in
the front passenger seat status. For ex-
ample, if a large adult who is sitting in the
front passenger seat exits the vehicle, the
front 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 passen-
ger air bag system, the supplemental air
bag warning light
, located in the me-
ter and gauges area of the instrument
panel, will blink. Have the system checked. It
is recommended that you visit a NISSAN
dealer for this service.
Normal operation
In order for the occupant classification
sensor system to classif y the front passen-
ger based on weight, please follow the pre-
cautions and steps outlined below:
Precautions
• Make sure that there are no objects weighing over 2.2 lbs. (1 kg) hanging on
the seat or placed in the seatback pocket.
• Make sure that a child restraint or other object is not pressing against the rear of
the seatback.
• Make sure that a rear passenger is not pushing or pulling on the back of the front
passenger seat.
• Make sure that the front passenger seat or seatback is not forced back against an
object on the seat or floor behind it.
• Make sure that there is no object placed under the front passenger seat. Steps
1. Adjust the seat as outlined in the “Seats”
section of this manual. Sit upright, lean-
ing against the seatback, and centered
on the seat cushion with your feet com-
fortably extended to the floor.
2. Make sure there are no objects on your lap.
3. Fasten the seat belt as outlined in the “Seat belts” section of this manual.
4. Remain in this position for 30 seconds allowing the system to classif y the front
passenger before the vehicle is put into
motion.
5. Ensure proper classification by checking the front passenger air bag status light.
Safety-Seats, seat belts and supplemental restraint system1-65

NOTE:
This vehicle’s occupant classification
sensor system locks the classification
during driving so it is important that you
confirm that the front passenger is prop-
erly classified prior to driving. Also, the
occupant classification sensor system
may recalculate the weight of the occu-
pant when the vehicle comes to a stop
(i.e. stop light, stop sign, etc.), so front
passenger seat occupants should con-
tinue to remain seated as outlined
above.
Troubleshooting
If you think the front passenger air bag
status light is incorrect:
1. If the light is ON with no front passengerand no objects on the front passenger
seat:
This may be due to the following condi-
tions that may be interfering with the
weight sensors:
• An object weighing over 2.2 lbs. (1 kg) hanging on the seat or placed in the seat-
back pocket.
• A child restraint or other object pressing against the rear of the seatback. • A rear passenger pushing or pulling on
the back of the front passenger seat.
• Forcing the front seat or seatback against an object on the seat or floor be-
hind it.
• 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.
If the vehicle is moving, please come to a
stop when it is safe to do so. Check and
correct any of the above conditions. Re-
start the vehicle and wait 1 minute.
NOTE:
A system check will be performed during
which the front passenger air bag status
light will remain lit for about 7 seconds
initially.
If the light is still ON af ter this, the vehicle
should be checked as soon as possible. It is
recommended that you visit a NISSAN
dealer for this service.
2. If the light is ON with an adult occupying the front passenger seat:
• Occupant is a small adult — the air bag light is functioning as intended. The front passenger air bag and passen-
ger knee air bag are suppressed.
However, if the occupant is not a small
adult, then this may be due to the following
conditions that may be interfering with the
weight sensors:
• Occupant is not sitting upright, leaning against the seatback, and centered on
the seat cushion with his/her feet com-
fortably extended to the floor.
• A child restraint or other object pressing against the rear of the seatback.
• A rear passenger pushing or pulling on the back of the front passenger seat.
• Forcing the front seat or seatback against an object on the seat or floor be-
hind it.
• 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.
If the vehicle is moving, please come to a
stop when it is safe to do so. Check and
correct any of the above conditions. Re-
start the vehicle and wait 1 minute.

Other supplemental front-impact air
bag precautions
WARNING
• Do not place any objects on the
steering wheel pad or on the instru-
ment panel. Also, do not place any
objects between any occupant and
the steering wheel or instrument
panel. Such objects may become
dangerous projectiles and cause in-
jury if the front air bags inflate.
• Immediately af ter inflation, several
front 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 supplemental air bag system.
This is to prevent accidental inflation
of the supplemental air bag or dam-
age to the supplemental air bag
system.
• Do not make unauthorized changes
to your vehicle's electrical system,
suspension system or front end
structure. This could affect proper
operation of the front air bag system.
• 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.
• Removing or modif ying the front
passenger seat may affect the func-
tion of the air bag system and result
in serious personal injury. •
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 (weight 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.

This vehicle is equipped with supplemental
front air bag system for the driver and right
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.

Safety-Seats, seat belts and supplemental restraint system1-75

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
supplemental 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 frontal colli-
sions. Vehicle damage (or lack of it) is not
always an indication of proper front air bag
system operation.
The supplemental air bag system moni-
tors information from the crash zone sen-
sor, the Air bag Control Unit (ACU) and seat
belt buckle sensors that detect if the seat
belts are fastened. Inflator operation is
based on the severity of a collision and
whether the seat belts are being used. Only
one front air bag may inflate in a crash,
depending on the crash severity and
whether the front occupants are belted or
unbelted. This does not indicate improper
performance of the system. If you have any
questions about the performance of your
air bag system, it is recommended that you
visit a NISSAN dealer to obtain information
about 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 begin-
ning 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 driver and right
front passenger. 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,
other than the driver’s knee air bag, do not
provide restraint to the lower body.
Seat belts should be correctly worn and the
driver and passenger seated upright as far
as practical away from the steering wheel
or instrument panel. The front air bags in-
flate quickly in order to help protect thefront 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 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.
WARNING
• Do not place any objects on the
steering wheel pad or on the instru-
ment panel. Also, do not place any
objects between any occupant and
the steering wheel or instrument
panel. Such objects may become
dangerous projectiles and cause in-
jury if the front air bag inflates.
• Immediately af ter inflation, several
front air bag system components will
be hot. Do not touch them; you may
severely burn yourself.

•If there is an impact to your vehicle
from any direction, your Occupant
Classification Sensor (OCS) (if so
equipped) should be checked to
verif y it is still functioning correctly. It
is recommended that you visit a
NISSAN dealer for this service. The
OCS (weight sensor) (if so equipped)
should be checked even if no air bags
deploy as a result of the impact. Fail-
ure to verif y proper OCS (weight sen-
sor) (if so equipped) function may re-
sult in an improper air bag
deployment resulting in injury or
death.
