is
located on the instrument panel above the radio
controls. The light operates as follows:
●Unoccupied passenger’s seat: The
is
OFF and the front passenger air bag is OFF
and will not inflate in a crash.
●Passenger’s seat occupied by a small adult,
child or child restraint as outlined in this
section: The
illuminates to indicate
that the front passenger air bag is OFF and
will not inflate in a crash.
●Occupied passenger seat and the passen-
ger meets the conditions outlined in this
section: The light
is OFF to indicate
that the front passenger air bag is opera-
tional.
Front passenger air bag
The front passenger air bag is designed to auto-
matically 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 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 bagto certain front passenger seat occupants, such
as children, by requiring the air bag to be auto-
matically turned OFF.
The occupant classification sensor (pattern sen-
sor) is in the front passenger seat cushion and is
designed to detect an occupant and objects on
the seat. For example, if a child is in the front
passenger seat, the Advanced 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 sensor
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 out-
lined in this manual should not cause the passen-
ger air bag 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 upright, by sitting on an
edge of the seat, or by otherwise being out of
position) , this could cause the sensor to turn the
air bag OFF. Always be sure to be seated and
wearing the seat belt properly for the most effec-
tive protection by the seat belt and supplemental
air bag.
NISSAN recommends that pre-teens and chil-
dren be properly restrained in a rear seat.
NISSAN also recommends that appropriate childrestraints and booster seats be properly installed
in a rear seat. If this is not possible, the occupant
classification sensor is designed to operate as
described above to turn the front passenger air
bag OFF for specified child restraints as required
by the regulations. Failing to properly secure
child restraints and to use the ALR mode (child
restraint 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 re-
straints” earlier in this section for proper use and
installation.
If the front passenger seat is not occupied, the
passenger air bag is designed not to inflate in a
crash. However, heavy objects placed on the
seat could result in air bag inflation, because of
the object being detected by the occupant clas-
sification 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 passenger air bag status light, you can
monitor when the front passenger air bag is au-
tomatically turned OFF with the seat occupied.
The light will not illuminate when the front pas-
senger seat is unoccupied.
