2021 NISSAN MURANO sensor

Front passenger air bag
The front passenger air bag is designed to
automatically turn OFF when the vehicle is
operated under some conditions as de-
scribed below in accordance with U.S. regu-
lations. 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 requir-
ing the air bag to be automatically 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 NISSAN Ad-
vanced Air Bag System is designed to turn
the front passenger air bag OFF in accor-
dance with the regulations. Also, if a child
restraint of the type specified in the regula-
tions 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 outlined in this manual should not
cause the front passenger air bag and
front passenger supplemental knee 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
upright, by sitting on an edge of the seat, or
by otherwise being out of position), this
could cause the sensor to turn the front
passenger air bag and front passenger
supplemental knee 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.
NISSAN recommends that pre-teens and
children be properly restrained in a rear
seat. NISSAN also recommends that ap-
propriate child restraints and booster
seats be properly installed in a rear seat. If
this is not possible, the occupant classifica-
tion sensor is designed to operate as de-
scribed above to turn the front passenger
air bag and front passenger supplemental
knee air bag OFF for specified child re-
straints as required by the regulations. Fail-
ing to properly secure child restraints and
to use the ALR mode may allow the re-
straint to tip or move in a collision or sud-den stop. This can also result in the passen-
ger air bag and front passenger
supplemental knee air bag inflating in a
crash instead of being OFF. For additional
information about proper use and installa-
tion, see “Child restraints” (P. 1-27).
If the front passenger seat is not occupied,
the front passenger air bag and front pas-
senger supplemental knee air bag are de-
signed not to inflate in a crash. However,
heavy objects placed on the seat could re-
sult in air bag inflation, because of the ob-
ject’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 pas-
senger air bag and front passenger
supplemental knee air bag are automati-
cally turned OFF.
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
Safety-Seats, seat belts and supplemental restraint system1-61

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 vehicle
to 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.
• 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 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.
3. Fasten the seat belt as outlined in the “Seat belts” (P. 1-13) 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.
1-62Safety-Seats, seat belts and supplemental restraint system

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 passenger
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 be-
hind 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.
• The child restraint is not properly in- stalled, as outlined in the “Child restraints”
section of this manual.
• An object weighing over 9.1 lbs. (4 kg) hanging on the seat or placed in the seat-
back 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 be-
hind it.
• An object placed under the front passen- ger seat.
Safety-Seats, seat belts and supplemental restraint system1-63

• An object placed between the seat cush-ion 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
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. It is
recommended that you visit a NISSAN
dealer as soon as possible.
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.
• 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 are 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).
1-64Safety-Seats, seat belts and supplemental restraint system

•If there is an impact to your vehicle
from any direction, your Occupant
Classification Sensor (OCS) should be
checked to verif y it is still functioning
correctly. It is recommended that you
visit a NISSAN dealer for this service.
The OCS should be checked even if no
air bags deploy as a result of the im-
pact. Failure to verif y proper OCS
function may result in an improper
air bag deployment resulting in in-
jury or death.

Operation
The MIL will come on in one of two ways:
• MIL on steady — An emission control sys-tem malfunction has been detected.
Check the fuel-filler cap if the Loose Fuel
Cap warning appears in the vehicle infor-
mation display. If the fuel-filler cap is loose
or missing, tighten or install the cap and
continue to drive the vehicle. The
light should turn off af ter a few driving
trips. If thelight does not turn off
af ter a few driving trips, have the vehicle
inspected. It is recommended that you
visit a NISSAN dealer for this service. You
do not need to have your vehicle towed
to the dealer.
• MIL blinking — An engine misfire has been detected which may damage the emis-
sion control system. To reduce or avoid
emission control system damage:– do not drive at speeds above 45 mph (72 km/h).
– avoid hard acceleration or deceleration.
– avoid steep uphill grades.
– if possible, reduce the amount of cargo being hauled or towed. The MIL may stop blinking and come on
steady. Have the vehicle inspected. It is rec-
ommended that you visit a NISSAN dealer
for this service. You do not need to have
your vehicle towed to the dealer.
