2021 NISSAN TITAN stop

knee air bag are 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 under some conditions. Certain sen-
sors 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 up to
the approximate size and weight of a one
year old is properly restrained in the front
passenger seat, the NISSAN Advanced Air
Bag System is designed to turn the front
passenger air bag and passenger knee air
bag OFF. For a properly restrained child
who is larger than the approximate size
and weight of a one year old, the front pas-
senger air bag may or may not be auto-
matically turned OFF, depending on the
size of the child and the type of child re-
straint being used. Af ter installing the child
restraint and positioning the child, place
the ignition switch in the ON position: if the
front passenger air bag status light is illu-
minated, the front passenger air bag andpassenger knee air bag are OFF. If the front
passenger air bag status light is not illumi-
nated, the air bag will inflate in a crash.
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 to be
automatically turned OFF. For small adults
it may be turned OFF, however if the occu-
pant 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 passen-
ger air bag and passenger knee air bag
OFF. Always be sure to be seated and wear-
ing the seat belt properly for the most ef-
fective 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 passenger knee air bag OFF for
specified child restraints as required by the
regulations. Failing to properly secure childrestraints and to use the ALR mode may
allow the restraint to tip or move in a colli-
sion or sudden stop. This can also result in
the passenger air bag and passenger knee
air bag inflating in a crash instead of being
OFF. For additional information, see “Child
restraints” (P. 1-28).
If the front passenger seat is not occupied,
the front passenger air bag and passenger
knee air bag are 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 infla-
tion, such as if a child is standing on the
seat, or if two children are on the seat, con-
trary to the instructions in this manual. Al-
ways be sure that you and all vehicle occu-
pants are seated and restrained properly.
Using the front passenger air bag status
light, you can monitor when the front pas-
senger air bag and passenger knee air bag
are automatically turned OFF with the seat
occupied. The light will not illuminate when
the front passenger seat is unoccupied.
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 passenger knee air bag are

NOTE:
This vehicle’s occupant classification
sensor system locks the classification
during driving so it is important that you
confirm that the front passenger is prop-
erly classified prior to driving. Also, the
occupant classification sensor system
may recalculate the weight of the occu-
pant when the vehicle comes to a stop
(i.e. stop light, stop sign, etc.), so front
passenger seat occupants should con-
tinue 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 passengerand no objects on the front passenger
seat:
This may be due to the following condi-
tions that may be interfering with the
weight sensors:
• An object weighing over 2.2 lbs. (1 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.
• 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 vehicle
should be checked as soon as possible. It is
recommended that you visit a NISSAN
dealer 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 passenger air bag and passen-
ger 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.
