2023 NISSAN LEAF 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
front passenger air bag status light is not
illuminated (indicating that the front pas-
senger 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 restraint is in-
stalled properly, the seat belt is used prop-
erly and the occupant is positioned prop-
erly. If the front passenger air bag status
light is still not illuminated, reposition the
occupant 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 vehicle
to a NISSAN certified LEAF dealer. A NISSAN
certified LEAF dealer can check system
status by using a special tool. However, un-
til 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 cer-
tified LEAF 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.
• Make sure that a child restraint or other object is not pressing against the rear of
the seatback.
• Make sure that the 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 the “Seats” (P. 1-2) section of this manual. Sit upright,
leaning against the seatback, and cen-
tered on the seat cushion with your feet
comfortably extended 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 the“Seat belts” (P. 1-11) section of this
manual. 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 occupying
the front passenger seat:
• Occupant is a small adult — the air bag light is functioning as intended. The
front passenger air bag and front pas-
senger 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, lean-ing against the seatback, and cen-
tered on the seat cushion with his/her
feet comfortably extended to the floor.
• A child restraint or other object press- ing 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 pas- senger seat. • An object placed between the seat
cushion and center console or be-
tween 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 certified
LEAF 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

• The child restraint is not properly in-stalled, as outlined in the “Child re-
straints” (P. 1-22) section of this
manual.
• An object weighting over 9.1 lbs. (4 kg) hanging on the seat or placed in the
seatback pocket (if so equipped).
• A child restraint or other object press- ing against the rear or the seatback.
• A rear passenger pushing or pulling on the back of the front passenger seat.
pushing or pulling on the seatback 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 pas- senger 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. 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 OFF af ter this, the small
adult, child or child restraint should be re-
positioned in the rear seat and the vehicle
should be checked as soon as possible. It is
recommended that you visit a NISSAN cer-
tified LEAF dealer for this service.
3. If the light is OFF with no front passenger and no objects on the front passenger
seat the vehicle should be checked as
soon as possible. It is recommended
that you visit a NISSAN certified LEAF
dealer for this service.
Other supplemental front-impact air
bag precautions
WARNING
• Do not place any objects on the
steering wheel pad or on the instru-
ment panel. Also, do not place any
objects between any occupant and
the steering wheel or instrument
panel. Such objects may become
dangerous projectiles and cause in-
jury if the front air bags inflate.
• Do not place objects with sharp
edges on the seat. Also, do not place
heavy objects on the seat that will
leave permanent impressions in the
seat. Such objects can damage the
seat or occupant classification sen-
sor (weight sensor). This can affect
the operation of the air bag system
and result in serious personal injury.
• Do not use water or acidic cleaners
(hot steam cleaners) on the seat. This
can damage the seat or occupant
classification sensor. This can also
affect the operation of the air bag
system and result in serious personal
injury.
Safety–Seats, seat belts and supplemental restraint system1-59

•Immediately af ter inflation, several
front air bag system components will
be hot. Do not touch them; you may
severely burn yourself.
• No unauthorized changes should be
made to any components or wiring
of the supplemental air bag system.
This is to prevent accidental inflation
of the supplemental air bag or dam-
age to the supplemental air bag
system.
• Do not make unauthorized changes
to your vehicle’s electrical system,
suspension system or front end
structure. This could affect proper
operation of the front air bag system.
• Tampering with the front air bag sys-
tem may result in serious personal
injury. Tampering includes changes
to the steering wheel and the instru-
ment panel assembly by placing ma-
terial over the steering wheel pad
and above the instrument panel or
by installing additional trim material
around the air bag system.
• Removing or modif ying the front
passenger seat may affect the func-
tion of the air bag system and result
in serious personal injury. •
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 is not specifically designed to
assure proper air bag operation. Ad-
ditionally, 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 certified LEAF dealer for work
on and around the front air bag sys-
tem. It is also recommended that you
visit a NISSAN certified LEAF dealer
for installation of electrical equip-
ment. The Supplemental Restraint
System (SRS) wiring harnesses*
should not be modified or discon-
nected. Unauthorized electrical test
equipment and probing devices
should not be used on the air bag
system.
• A cracked windshield should be re-
placed immediately by a qualified re-
pair 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.
