Sensors INFINITI QX70 2017 Owner's Manual

Status light
The front passenger seat is equipped with an
occupant classification sensor (weight sensor)
that turns the front passenger air bag on or off
depending on the weight applied to the front
passenger seat. The status of the front passen-
ger air bag (ON or OFF) is indicated by the front
passenger 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
on the instrument panel illuminates for about
7 seconds and then turns off or remains illumi-
nated depending on the front passenger seat
occupied status. The light operates as follows:
● Unoccupied front passenger’s seat:
The
light is OFF and the front passen-
ger air bag is OFF and will not inflate in a
crash.
● Front passenger seat occupied by a small
adult, child or child restraint as outlined in
this section: The
light illuminates to
indicate that the front passenger air bag is
OFF and will not inflate in a crash.
● Occupied front passenger seat and the pas-
senger meets the conditions as outlined in
this section: The
light is OFF to indi-
cate that the front passenger air bag is op-
erational. In addition to the above, certain objects placed
on the front passenger seat may also cause the
light to operate as described above depending
on their weight.
For additional information related to the normal
operation and troubleshooting of this occupant
classification sensor system, please refer to
“Normal operation” and “Troubleshooting” in this
section.
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 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-

●Make sure that the front passenger seat
head restraint/headrest does not contact
the roof when adjusting the front passenger
seat.
Steps 1. Adjust the seat as outlined in the “Seats” section of this manual. 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.
3. Fasten the seat belt as outlined in the “Seat belts” section of this manual.
4. Remain in this position for 30 seconds al- lowing the system to classify the front pas-
senger 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 sen-
sor system locks the classification during
driving so it is important that you confirm
that the front passenger is properly classi-
fied prior to driving. Also, the occupant
classification sensor system may recalcu-
late the weight of the occupant when the
vehicle comes to a stop (i.e. stop light, stop
sign, etc.) , 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 no front passenger and no objects on the front passenger seat:
This may be due to the following conditions that
may be interfering with the weight sensors: ● An object weighing over 9.1 lbs (4 kg) hang-
ing on the seat or placed in the seatback
pocket.
● 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 passenger
seat.
● An object placed between the seat cushion
and center console or between the seat
cushion and the door.
● The front passenger seat head
restraint/headrest 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 during
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 vehicle should be
checked as soon as possible. It is recommended
that you visit an INFINITI retailer for this service.
2. If the light is ON with an adult occupying the front passenger seat:
● Occupant is a small adult — the air bag light
is functioning 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 interfering with the weight sensors:● Occupant is not sitting upright, leaning
against the seatback, and centered on the
seat cushion with his/her feet comfortably
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 passenger
seat.
● An object placed between the seat cushion
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. Restart 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 after 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 recommended that you visit an
INFINITI retailer for this service.
3. If the light is OFF with a small adult, child or child restraint occupying the front passen-
ger seat.
This may be due to the following conditions
that may be interfering with the weight sen-
sors:
● Small adult or child is not sitting upright,
leaning against the seatback, and centered
on the seat cushion with his/her feet com-
fortably extended to the floor.
● The child restraint is not properly installed,
as outlined in the “Child restraints” section of
this manual.
● An object weighing over 9.1 lbs (4 kg) hang-
ing on the seat or placed in the seatback
pocket. ●
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 passenger
seat.
● An object placed between the seat cushion
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. Restart 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 after this, the small adult,
child or child restraint should be repositioned in
the rear seat and the vehicle should be checked
as soon as possible. It is recommended that you
visit an INFINITI retailer for this service.
