2023 NISSAN SENTRA sensor

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.
1-58Safety-Seats, seat belts and supplemental restraint system

•Modif ying or tampering with the
front passenger seat may result in
serious personal injury. For example,
do not change the front seats by
placing material on the seat cushion
or by installing additional trim mate-
rial, such as seat covers, on the seat
that are not specifically designed
to assure proper air bag operation.
Additionally, do not stow any objects
under the front passenger seat or the
seat cushion and seatback. Such ob-
jects may interfere with the proper
operation of the occupant classifica-
tion sensor (weight sensor).
• No unauthorized changes should be
made to any components or wiring
of the seat belt system. This may af-
fect the front air bag system. Tam-
pering with the seat belt system may
result in serious personal injury. •
It is recommended that you visit a
NISSAN dealer for work on and
around the front air bag. It is also rec-
ommended that you visit a NISSAN
dealer for installation of electrical
equipment. The Supplemental Re-
straint System (SRS) wiring har-
nesses* should not be modified or
disconnected. Unauthorized electri-
cal test equipment and probing de-
vices should not be used on the air
bag system.
• A cracked windshield should be re-
placed immediately by a qualified
repair facility. A cracked windshield
could affect the function of the
supplemental air bag system.
*The SRS wiring harness connectors are
yellow and orange for easy identification.
When selling your vehicle, we request that
you inform the buyer about the front air
bag system and guide the buyer to the
appropriate sections in this Owner's
Manual.
