away as practical from the steer-
ing wheel or instrument panel.
Always use the seat belts.
. The driver and front passenger
seat belt buckles are equipped
with sensors that detect if the
seat belts are fastened. The Ad-
vanced Air Bag System monitors
the severity of a collision and seat
belt usage then inflates the air
bags as needed. Failure to prop-
erly wear seat belts can increase
the risk or severity of injury in an
accident.
. The front passenger seat is
equipped with occupant classifi-
cation sensors (weight sensors)
that turn the front passenger air
bag OFF under some conditions.
These sensors are 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. See
“Front passenger air bag and
status light” (P.1-48).
. Keep hands on the outside of the
steering wheel. Placing them in-
side the steering wheel rim could
increase the risk that they are
injured if the front air bag in- flates.

NISSAN ADVANCED AIR BAG SYS-
TEM (front seats)
WARNING
To ensure proper operation of the
passenger’s Advanced Air Bag sys-
tem, please observe the following
items.
.
Do not allow a passenger in the
rear seat to push or pull on the
seatback pocket.
. Do not place heavy loads heavier
than 9.1 lbs (4 kg) on the seat-
back, head restraint or in the
seatback pocket.
. Make sure nothing is pressing
against the rear of the seatback,
such as a child restraint installed
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.
. Be sure that the front passenger
seat does not contact the rear
seat, instrument panel, etc., or the
head restraint does not contact
the roof.
. Do not position the front passen-
ger seat so it contacts the rear
seat. If the front seat does con-
tact 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 sup-
plemental air bag warning light
may flash.
. If a forward facing child restraint
is installed in the front passenger
seat, do not position the front
passenger seat so the child re-
straint contacts the instrument
panel. If the child restraint does
contact the instrument panel, the
system may determine the seat is
occupied and the passenger air
bag may deploy in a collision.
Also the front passenger air bag
status light may not illuminate.
See “Child restraints” (P.1-20) for
information about installing and
using child restraints. .
Confirm the operating condition
with the front passenger air bag
status light.
. If you notice that the front pas-
senger air bag status light is not
operating as described in this
section, it is recommended you
visit a NISSAN dealer to check the
passenger seat Advanced Air Bag
System.
. Until you have confirmed with
your dealer that your passenger
seat Advanced Air Bag is working
properly, position the occupants
in the rear seating positions.
This vehicle is equipped with the NISSAN
Advanced Air Bag System for the driver
and front passenger seats. This system is
designed to meet certification require-
ments under U.S. regulations. It is also
permitted in Canada. All of the informa-
tion, cautions and warnings in this
manual apply and must be followed.
The driver supplemental front-impact air
bag is located in the center of the
steering wheel. The passenger supple-
mental front-impact air bag is mounted in
the instrument panel 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 frontal
collisions. Vehicle damage (or lack of it) is
not always an indication of proper front
air bag operation.
The NISSAN Advanced Air Bag System has
dual stage air bag inflators. The system
monitors information from the Air bag
Control Unit (ACU), seat belt buckle sen-
sors and the occupant classification sen-
sors (weight sensors). Inflator operation is
based on the severity of a collision and
seat belt usage for the driver. For the
front passenger, the occupant classifica-
tion sensors are also monitored. Based on
information 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 pas-
senger air bag may be automatically
turned OFF under some conditions, de-
pending on the information provided by
the occupant classification sensors. If the
front passenger air bag is OFF, the front
passenger air bag status light will be
illuminated. (See “Front passenger air
bag and status light” (P.1-48) for further
details.) One front air bag inflating does
not indicate improper performance of the
system.
Safety — Seats, seat belts and supplemental restraint system1-47

child restraints can increase the risk
or severity of injury in an accident.
Status light:
The front passenger seat is equipped with
occupant classification sensors (weight
sensors) that turn the front passenger air
bag on or off depending on the weight
applied to the front passenger seat. The
status of the front passenger air bag (ON
or OFF) is indicated by the front passen-
ger air bag status light
which is
located on the instrument panel. After
the ignition switch is placed in the ON
position, the front passenger air bag
status light illuminates for about 7 sec-
onds and then turns off or remains
illuminate depending on the front pas-
senger seat occupied status. The light
operates as follows:
CONDITION DESCRIPTION PASSENGER AIR BAG
INDICATOR LIGHT ()FRONT PASSENGER
AIR BAG STATUS
Empty Empty front passen-
ger seat ON (illuminated)
INHIBITED
Nobody/Somebody Bag or Child or Child
Restraint or Small
Adult in front pas- senger 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 related to the
normal operation and troubleshooting of
this occupant classification sensor sys-
tem, please refer to “Normal operation”
(P.1-51) and “Troubleshooting” (P.1-51) in
this section.
Front passenger air bag:
The front passenger air bag is designed
to automatically turn OFF when the
vehicle is operated under some condi-
tions as described below as permitted by
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 passen-
ger seat occupants, such as children, by
requiring the air bag to be automatically
turned OFF.
The occupant classification sensors
(weight sensors) are on the seat cushion
frame under the front passenger seat and
are designed to detect an occupant and
objects on the seat. For example, if a child
is in the front passenger seat, the Ad-
vanced Air Bag System 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
regulations is on the seat, the occupant
classification sensors can detect it 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 passenger air bag
Safety — Seats, seat belts and supplemental restraint system1-49

1-50Safety — Seats, seat belts and supplemental restraint system
to be automatically turned OFF. For small
adults it may be turned OFF, however, if
the occupant does not sit in the seat
properly (for example, by not sitting up-
right, by sitting on an edge of the seat, or
by otherwise being out of position), this
could cause the sensors to turn the 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
classification sensors are designed to
operate as described above to turn the
front passenger air bag OFF for specified
child restraints. Failing to properly secure
child restraints and to use the Automatic
Locking Retractor (ALR) mode (child re-
straint 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 instead of being
OFF. (See “Child restraints” (P.1-20) for
proper use and installation.)
If the front passenger seat is not occu-
pied, the passenger air bag is designed
not to inflate in a crash. However, heavyobjects placed on the seat could result in
air bag inflation, because of the object
being detected by the occupant classifi-
cation sensors. 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 is automatically turned
OFF.
If an adult occupant is in the seat but the
front passenger 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.
If a child restraint must be used in the
front seat, the front passenger air bag
status light may or may not be illumi-
nated, depending on the size of the child
and the type of child restraint being used.
If the front passenger air bag status light
is not illuminated (indicating that the air
bag might inflate in a crash), it could be
that the child restraint or seat belt is not
being used properly. Make sure that the
child restraint is installed properly, the
seat belt is used properly and the occu-pant is positioned properly. If the front
passenger air bag status light is not
illuminated, reposition the occupant or
child restraint in a rear seat.
If the front passenger air bag status light
will not illuminate even though you be-
lieve that the child restraint, the seat belts
and the occupant are properly positioned,
it is recommended that you take your
vehicle to a NISSAN dealer. A NISSAN
dealer can check the system status by
using a special tool. However, until you
have confirmed with your dealer that
your air bag is working properly, reposi-
tion 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 passenger seat status. This
is normal system operation and does not
indicate a malfunction.
If a malfunction occurs in the front
passenger air bag system, the supple-
mental air bag warning light
, located
in the meters and gauges area, will
illuminate. Have the system checked. It is
recommended you visit a NISSAN dealer
for this service.

Normal operation:
In order for the occupant classification
sensor system to classify the front pas-
senger based on weight, please follow the
precautions and steps outlined below:
Precautions:
.Make sure that there are no objects
weighing over 9.1 lbs (4 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.
. Make sure that the front passenger
seat head restraint does not contact
the roof when adjusting the front
passenger seat. Steps:
1. Adjust the seat as outlined. (See “Seats” (P.1-2).) Sit upright, leaning
against the seatback, and centered
on the seat cushion with your feet
comfortably extended to the floor.
2. Make sure there are no objects on your lap.
3. Fasten the seat belt as outlined. (See “Seat belts” (P.1-10).) Front passenger
seat belt buckle status is monitored
by the occupant classification system,
and is used as an input to determine
occupancy status. So, it is highly
recommended that the front passen-
ger fasten their seat belt.
4. Remain in this position for 30 seconds allowing the system to classify the
front passenger before the vehicle is
put into motion.
5. Ensure proper classification by check- ing the front passenger air bag status
light.
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
properly classified prior to driving. Also,
the occupant classification sensor sys-
tem may recalculate the weight of the occupant under some conditions (both
while driving and when stopped), so the
front passenger seat occupant should
continue 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 an adult occupying the front passenger seat:
.Occupant is a small adult — the front
passenger air bag status light is func-
tioning as intended. The front passen-
ger air bag is suppressed.
However, if the occupant is not a small
adult, then this may be due to the
following conditions that may be interfer-
ing with the weight sensors:
. Occupant is not sitting upright, lean-
ing against the seatback, and cen-
tered on the seat cushion with his/her
feet comfortably extended to the
floor.
. A child restraint or other object press-
ing 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
behind it.
Safety — Seats, seat belts and supplemental restraint system1-51

1-52Safety — Seats, seat belts and supplemental restraint system
.An object placed under the front
passenger seat.
. An object placed between the seat
cushion and center console or be-
tween 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.
Restart the vehicle and wait 1 minute.
NOTE:
A system check will be performed dur-
ing which the front passenger air bag
status light will remain lit for about 7
seconds initially.
If the light is still ON after this, the person
should be advised not to ride in the front
passenger seat and it is recommended
that the vehicle should be checked by a
NISSAN dealer as soon as possible.
2. If the light is OFF with a small adult, child or child restraint occupying the front
passenger seat.
This may be due to the following condi-
tions that may be interfering with the
weight sensors:
.Small adult or child is not sitting
upright, leaning against the seatback,
and centered on the seat cushion with
his/her feet comfortably extended to
the floor. .
The child restraint is not properly
installed, as outlined. (See “Child re-
straints” (P.1-20).)
. An object weighing over 9.1 lbs (4 kg)
hanging on the seat or placed in the
seatback pocket.
. A child restraint or other object press-
ing 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
behind it.
. An object placed under the front
passenger seat.
. An object placed between the seat
cushion and center console.
. The front passenger seat head re-
straint contacting the roof.
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.
Restart the vehicle and wait 1 minute.
NOTE:
A system check will be performed dur-
ing which the front passenger air bag
status light will remain lit for about 7
seconds initially.
If the light is still OFF after this, the small
adult, child or child restraint should be repositioned in the rear seat and it is
recommended that the vehicle should be
checked by a NISSAN dealer as soon as
possible.
3. If the light is OFF with no front passenger
and no objects on the front passenger
seat, the vehicle should be checked as
soon as possible. It is recommended you
visit a NISSAN dealer for this service.
Other supplemental front-impact
air bag precautions
WARNING
.Do not place any objects on the
steering wheel pad or on the
instrument panel. Also, do not
place any objects between any
occupant and the steering wheel
or instrument panel. Such objects
may become dangerous projec-
tiles and cause injury if the front
air bags inflate.
. Do not place objects with sharp
edges on the seat. Also, do not
place heavy objects on the seat
that will leave permanent impres-
sions in the seat. Such objects
can damage the seat or occupant
classification sensors (weight
sensors). This can affect the op-

eration of the air bag system and
result in serious personal injury.
. Do not use water or acidic clea-
ners (hot steam cleaners) on the
seat. This can damage the seat or
occupant classification sensors.
This can also affect the operation
of the air bag system and result in
serious personal injury.
. Immediately after inflation, sev-
eral front air bag system compo-
nents 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 supple-
mental air bag or damage to the
supplemental air bag system.
. Do not make unauthorized
changes to your vehicle’s electri-
cal system, suspension system or
front end structure. This could
affect proper operation of the
front air bag system.
. Tampering with the front air bag
system may result in serious per-
sonal injury. Tampering includes
changes to the steering wheel and the instrument panel assem-
bly by placing material over the
steering wheel pad and above the
instrument panel or by installing
additional trim material around
the air bag system.
. Removing or modifying the front
passenger seat may affect the
function of the air bag system
and result in serious personal
injury.
. Modifying 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 ad-
ditional trim material, such as
seat covers, on the seat that is
not specifically designed to as-
sure proper air bag operation.
Additionally, do not stow any
objects under the front passen-
ger seat or the seat cushion and
seatback. Such objects may inter-
fere with the proper operation of
the occupant classification sen-
sors.
. No unauthorized changes should
be made to any components or
wiring of the seat belt system.
This may affect the front air bag system. Tampering with the seat
belt system may result in serious
personal injury.
. It is recommended you visit a
NISSAN dealer for work on and
around the front air bag. It is also
recommended you visit a NISSAN
dealer for installation of electrical
equipment. The Supplemental
Restraint System (SRS) wiring
harnesses* should not be modi-
fied or disconnected. Unauthor-
ized electrical test equipment
and probing devices should not
be used on the air bag system.
. A cracked windshield should be
replaced immediately by a quali-
fied repair facility. A cracked
windshield could affect the func-
tion 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 Man-
ual.

REPAIR AND REPLACEMENT PRO-
CEDURE
The front air bags, side air bags, curtain
air bags and pretensioners are designed
to activate on a one-time-only basis. As a
reminder, unless it is damaged, the sup-
plemental air bag warning light will re-
main illuminated after inflation has
occurred. These systems should be re-
paired and/or replaced as soon as possi-
ble. It is recommended you visit a NISSAN
dealer for this service.
When maintenance work is required on
the vehicle, the front air bags, side air
bags, curtain air bags and pretensioners
and related parts should be pointed out
to the person performing the mainte-
nance. The ignition switch should always
be in the LOCK position when working
under the hood or inside the vehicle.
WARNING
.Once a front air bag, side air bag
or curtain air bag has inflated, the
air bag module will not function
again and must be replaced. Ad-
ditionally, the activated preten-
sioners must also be replaced.
The air bag module and preten-
sioner should be replaced. It is recommended you visit a NISSAN
dealer for this service. However,
the air bag modules and preten-
sioner system cannot be re-
paired.
. The front air bag, side air bag and
curtain air bag systems, and pre-
tensioner system should be in-
spected if there is any damage to
the front end or side portion of
the vehicle. It is recommended
you visit a NISSAN dealer for this
service.
. If you need to dispose of a sup-
plemental air bag or pretensioner
or scrap the vehicle, it is recom-
mended you visit a NISSAN deal-
er. Correct supplemental air bag
and pretensioner system dispo-
sal procedures are set forth in the
appropriate NISSAN Service Man-
ual. Incorrect disposal procedures
could cause personal injury.
. If there is an impact to your
vehicle from any direction, your
Occupant Classification Sensor
(OCS) should be checked to verify
it is still functioning correctly. It is
recommended that you visit a
NISSAN dealer for this service.
The OCS should be checked even
if no air bags deploy as a result of the impact. Failure to verify prop-
er OCS function may result in an
improper air bag deployment re-
sulting in injury or death.
