WARNING
●The front air bags ordinarily will not
inflate in the event of a side impact, rear
impact, rollover, or lower severity fron-
tal collision. Always wear your seat
belts to help reduce the risk or severity
of injury in various kinds of accidents.
● The front passenger air bag will not
inflate if the passenger air bag status
light is lit or if the front passenger seat
is unoccupied. For additional informa-
tion, refer to “Front passenger air bag
and status light” in this section. ●
The seat belts and the front air bags are
most effective when you are sitting well
back and upright in the seat. The front
air bags inflate with great force. Even
with the NISSAN Advanced Air Bag Sys-
tem, if you are unrestrained, leaning
forward, sitting sideways or out of posi-
tion in any way, you are at greater risk of
injury or death in a crash. You may also
receive serious or fatal injuries from the
front air bag if you are up against it
when it inflates. Always sit back against the seatback and as far away as practi-
cal from the steering wheel or instru-
ment panel. Always properly use the
seat belts.
● The driver and front passenger seat belt
buckles are equipped with sensors that
detect if the seat belts are fastened. The
NISSAN Advanced Air Bag System
monitors the severity of a collision and
inflates the air bags as needed. Failure
to properly wear seat belts can increase
the risk or severity of injury in an
accident.
● The front passenger seat is equipped
with an occupant classification sensor
(weight sensor) that turns the front pas-
senger air bag OFF under some condi-
tions. This sensor is only used in this
seat. Failure to be properly seated and
wearing the seat belt can increase the
risk or severity of injury in an accident.
For additional information, refer to
“Front passenger air bag and status
light” in this section.
● Keep hands on the outside of the steer-
ing wheel. Placing them inside the
steering wheel rim could increase the
risk that they are injured when the front
air bag inflates.

WARNING
To ensure proper operation of the passen-
ger’s NISSAN Advanced Air Bag System,
please observe the following items.
●Do not allow a passenger in the rear
bench seats (if so equipped) to push or
pull on the seatback pocket.
● Do not place heavy loads heavier than
1 kg (2.2 lb) on the seatback, head re-
straint or in the seatback pocket.
● Do not store luggage behind the seat
that can press into the seatback.
● Do not position the front passenger
seat so it contacts the rear bench seats
(if so equipped) . If the front seat does
contact the rear bench seats (if so
equipped) , the air bag system may de-
termine a sensor malfunction has oc-
curred and the front passenger air bag
status light may illuminate and the
supplemental air bag warning light may
flash. ●
If a forward-facing child restraint is in-
stalled in the front passenger seat, do
not position the front passenger seat so
the child restraint contacts the instru-
ment panel. If the child restraint does
contact the instrument panel, the sys-
tem may determine the seat as occu-
pied and the passenger air bag may
deploy in a collision. Also the front pas-
senger air bag status light may not illu-
minate. For additional information
about installing and using child re-
straints, refer to “Child restraints” in
this section.
● Confirm the operating condition with
the front passenger air bag status light.
● If you notice that the front passenger air
bag status light is not operating as de-
scribed in this section, get the occupant
classification system checked. It is rec-
ommended that you take your vehicle to
a NISSAN dealer for this service.
● Until you have confirmed with your
dealer that your passenger seat occu-
pant classification system is working
properly, position the occupants in the
rear seating positions (if so equipped) .
Do not use the front seat or transport a
child in the vehicle (Single Cab) . This vehicle is equipped with the NISSAN Ad-
vanced Air Bag System for the driver and front
passenger seats.
All of the information, cau-
tions and warnings in this manual still ap-
ply and must be followed.
The driver supplemental front-impact air bag is
located in the center of the steering wheel. The
front passenger supplemental front-impact air
bag is mounted in the dashboard above the glove
box. The front air bags are designed to inflate in
higher severity frontal collisions, although they
may inflate if the forces in another type of collision
are similar to those of a higher severity frontal
impact. They may not inflate in certain frontal
collisions. Vehicle damage (or lack of it) is not
always an indication of proper front air bag sys-
tem operation.
The NISSAN Advanced Air Bag System monitors
information from the crash zone sensor and the
Air bag Control Unit (ACU) . Inflator operation is
based on the severity of a collision and seat belt
usage for the driver. For the front passenger, the
occupant classification sensor is also monitored.
Based upon the information from the sensor, only
one front air bag may inflate in a crash, depending
on the crash severity. Additionally, the front pas-
senger air bag may be automatically turned off
under some conditions, depending on the weight
detected on the front passenger seat and how
the seat belt is used. If the front passenger air bag

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 may or may not
illuminate, depending on the size of the oc-
cupant or the type of child restraint being
used. When the
light is illuminated,
the front passenger air bag is OFF and will
not inflate in a crash. For additional informa-
tion, refer to “Front passenger air bag” in this
section. ●
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 under some conditions.
Certain sensors are used to meet the require-
ments. 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 OFF. For a properly restrained
child who is larger than the approximate size and
weight of a one year old, the front passenger air
bag may or may not be automatically turned OFF,
depending on the size of the child and the type of
child restraint being used. After 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 illuminated, the
air bag is OFF. If the front passenger air bag
status light is not illuminated, the air bag will
inflate in a crash.
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
Safety—Seats, seat belts and supplemental restraint system1-61

properly for the most effective protection by the
seat belt and supplemental air bag.
NISSAN recommends that pre-teens and chil-
dren be properly restrained in a rear seat (if so
equipped) . NISSAN also recommends that ap-
propriate child restraints and booster seats be
properly installed in a rear seat (if so equipped) . 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 regu-
lations. 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 passenger air bag inflating
in a crash instead of being OFF. For additional
information about proper use and installation,
refer to “Child restraints” in this section.
If the front passenger seat is not occupied, the
front passenger air bag is 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 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 passenger air bag is
automatically turned OFF with the seat occupied.
The light will not illuminate when the front pas-
senger seat is unoccupied.
If an adult occupant is in the seat but the front
passenger air bag status light is illuminated (indi-
cating that the air bag is 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, depending on the size of
the child and the type of child restraint being
used. Always make sure that the child restraint is
installed properly, the seat belt is used properly
and the occupant is positioned properly.
If necessary, a NISSAN dealer can check system
operation by using a special tool. Until you have
confirmed with a dealer that your air bag is work-
ing properly, reposition the occupant or child
restraint in a rear seat (if so equipped) . Do not
use the front seat or transport a child in the
vehicle (Single Cab) .
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 passen-
ger seat status. For example, if a large adult who
is sitting in the front passenger seat exits thevehicle, the front passenger air bag status light
will go from OFF to ON for a few seconds and
then to OFF. This is normal system operation and
does not indicate a malfunction.
If a malfunction occurs in the front passenger air
bag system, the supplemental air bag warning
light
, located in the meter and gauges area
of the instrument panel, will blink. Have the sys-
tem checked. It is recommended that you visit a
NISSAN dealer for this service.
Normal operation
In order for the occupant classification sensor
system to classify the front passenger based on
weight, please follow the precautions and steps
outlined below:
Precautions
● Make sure that there are no objects weigh-
ing over 2.2 lbs (1 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 push-
ing or pulling on the back of the front pas-
senger seat.
1-62Safety—Seats, seat belts and supplemental restraint system

●Make sure that the front passenger seat or
seatback is not forced back against an ob-
ject 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” 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 1 kg (2.2 lbs) 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.
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 recom-
mended 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 passen-
ger air bag is suppressed.
Safety—Seats, seat belts and supplemental restraint system1-63

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 a
NISSAN 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 instrument panel.
Also, do not place any objects between
any occupant and the steering wheel or
instrument panel. Such objects may be-
come dangerous projectiles and cause
injury if the front air bags inflate.
● Immediately after inflation, several
front air bag system components will be
hot. Do not touch them; you may se-
verely 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 damage to the
supplemental air bag system.
● Do not make unauthorized changes to
your vehicle’s electrical system, sus-
pension system or front end structure.
This could affect proper operation of
the front air bag system.
● Tampering with the front air bag system
may result in serious personal injury.
Tampering includes changes to the
steering wheel and the instrument
panel assembly by placing material
over the steering wheel pad and above
the instrument panel or by installing
additional trim material around the air
bag system.
● Removing or modifying the front pas-
senger seat may affect the function of
the air bag system and result in serious
personal injury.
