2011 INFINITI QX ECU

Status light :
The front passenger air bag status light
is located on the instrument panel.
The light operates as follows:
●Unoccupied passenger seat: The
light
is OFF and the front passenger air bag is OFF
and will not inflate in a crash.
● Passenger seat occupied by a small adult,
child or child restraint as outlined in this
section: The
light illuminates to indi-
cate that the front passenger air bag is OFF
and will not inflate in a crash.
● Occupied passenger seat and the passenger
meets the conditions outlined in this sec-
tion: The
light is OFF to indicate that
the front passenger air bag is operational.
Front passenger air bag :
The front passenger air bag is designed to
automatically turn OFF when the vehicle is
operated under some conditions 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 passenger 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 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 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 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 effective protection by the seat belt
and supplemental air bag.
INFINITI recommends that pre-teens and chil-
dren be properly restrained in a rear seat.
INFINITI also recommends that appropriatechild restraints and booster seats be properly
installed in a rear seat. If this is not possible,
the occupant classification sensors are de-
signed to operate as described above to turn
the front passenger air bag OFF for specified
child restraints. Failing to properly secure child
restrains and to use the ALR mode may allow
the restraint to tip or move in an accident or
sudden stop. This can also result in the passen-
ger air bag inflating in a crash instead of being
OFF. (See “CHILD RESTRAINTS” 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
classification 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 passenger air bag status light, you
can monitor when the front passenger air bag is
automatically turned OFF with the seat occu-
pied. The light will not illuminate when the front
passenger seat is unoccupied.
