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

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
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.
1-56Safety-Seats, seat belts and supplemental restraint system

If an adult occupant is in the seat but the
front passenger air bag status light is illu-
minated (indicating that the front passen-
ger air bag and front passenger supple-
mental knee air bag are 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. If the air
bag status light is not illuminated (indicat-
ing that the front passenger air bag and
front passenger supplemental knee 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 re-
straint is installed properly, the seat belt is
used properly and the occupant is posi-
tioned properly. If the air bag status light is
still not illuminated, reposition the occu-
pant or child restraint in a rear seat.
If the front passenger air bag status light
will not illuminate even though you believe
that the child restraint, the seat belts and
the occupant are properly positioned, it is
recommended that you take your vehicleto a NISSAN dealer. A NISSAN dealer can
check system status by using a special
tool. However, 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. This is nor-
mal system operation and does not indi-
cate 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 be illuminated (blinking or
steadily lit). 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 9.1 lbs. (4 kg) hanging on
the seat or placed in the seatback pocket
(if so equipped).
• 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 “Seats” (P. 1-2). Sit upright, leaning against the
seatback, and centered on the seat
cushion with your feet comfortably ex-
tended to the floor.
2. Make sure there are no objects on your lap.
Safety-Seats, seat belts and supplemental restraint system1-57

3. Fasten the seat belt as outlined in “Seatbelts” (P. 1-12). Front passenger seat belt
buckle status is monitored by the occu-
pant classification system, and is used
as an input to determine occupancy
status. So, it is highly recommended that
the front passenger fasten their seat
belt.
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.
NOTE:
This vehicle’s occupant classification
sensor system generally keeps the clas-
sification locked during driving, so it is
important that you confirm that the
front passenger is properly classified
prior to driving. However, the occupant
classification sensor may recalculate the
weight of the occupant under some con-
ditions (both while driving and when
stopped), so front passenger seat occu-
pants 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 occupyingthe front passenger seat:
• Occupant is a small adult — the air bag light is functioning as intended. The front
passenger air bag and front passen-
ger supplemental 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 behind 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 person
should be advised not to ride in the front
passenger seat and the vehicle should be
checked as soon as possible. It is recom-
mended that you visit a NISSAN dealer for
this service.
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 cen-
tered on the seat cushion with his/her
feet comfortably extended to the floor.

back pocket (if so equipped).
• 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.
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 OFF af ter this, the small
adult, child or child restraint should be re-
positioned in the rear seat and the vehicle
should be checked as soon as possible. It is
recommended that you visit a NISSAN
dealer for this service.
3. If the light is OFF with no front passenger
and no objects on the front passenger
seat, the vehicle should be checked. It is
recommended that you visit a NISSAN
dealer as soon as possible.
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 damage 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.
