ECU INFINITI Q50 HYBRID 2017 Owner's Manual

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 auto-
matically 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 INFINITI Advanced Air Bag System is de-
signed to turn the front 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, its weight and the 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 out-
lined in this manual should not cause the front
passenger 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 up-
right, 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 appropriate child
restraints 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 may
allow the restraint to tip or move in a collision or
sudden stop. This can also result in the passen-
ger air bag inflating in a crash instead of being
OFF. For additional information about proper use
and installation, refer to “Child restraints” in this
section.
If the front passenger seat is not occupied, the
front 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’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 is
automatically turned OFF.If an adult occupant is in the seat but the front
passenger air bag status light is illuminated (indi-
cating that the air bag is 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, depending on the size of
the child and the type of child restraint being
used. If the 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 occupant is posi-
tioned properly. If the air bag status light is still not
illuminated, reposition the occupant or child re-
straint 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 vehicle to an INFINITI retailer. An
INFINITI retailer can check system status by us-
ing a special tool. However, until you have con-
firmed with a retailer that your air bag is working
properly, reposition the occupant or child re-
straint in a rear seat.
