back against the seatback and as
far-away as practical from the steer-
ing wheel or instrument panel. Al-
ways 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 Advanced Air Bag
System monitors the severity of a
collision and seat belt usage then
inflates the air bags. Failure to
properly wear seat belts can in-
crease the risk or severity of injury
in an accident.
. The front passenger seat is
equipped with occupant classifica-
tion sensors (weight sensors) that
turn the front passenger air bag
OFF under some conditions. 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. See “Front passenger air
bag and status light” (P.1-55) .
. Keep hands on the outside of the
steering wheel. Placing them inside
the steering wheel rim could in-
crease the risk of injury if the front air bag inflates.

.The seat belts, the side air bags and
curtain air bags are most effective
when you are sitting well back and
upright in the seat. The side air bags
and curtain air bags inflate with
great force. Do not allow anyone to
place their hand, leg or face near the
side air bags on the side of the
seatback of the front seat or near
the side roof rails. Do not allow
anyone sitting in the front seats or
rear outboard seats to extend their
hand out of the window or lean
against the door. Some examples of
dangerous riding positions are
shown in the previous illustrations.
. When sitting in the rear seat, do not
hold onto the seatback of the front
seat. If the side air bag inflates, you
may be seriously injured. Be espe-
cially careful with children, who
should always be properly re-
strained. Some examples of danger-
ous riding positions are shown in
the illustrations.
. Do not use seat covers on the front
seatbacks. They may interfere with
side air bag inflation.

NISSAN ADVANCED AIR BAG SYS-
TEM (front seats)
WARNING
To ensure proper operation of the
passenger’s advanced air bag system,
please observe the following items.
.Do not allow a passenger in the rear
seat to push or pull on the seatback
pocket.
. Do not place heavy loads heavier
than 9.1 lbs. (4 kg) on the seatback
or in the seatback pocket. Do not
hang anything from the head re-
straint.
. Do not store cargo behind the seat
that can press into the seatback.
. Do not position the front passenger
seat so it contacts the rear seat. If
the front seat does contact the rear
seat, the air bag system may deter-
mine 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
installed in the front passenger
seat, do not position the front
passenger seat so the child restraint
contacts the instrument panel. If the
child restraint does contact the in-
strument panel, the system may
determine the seat is occupied and
the passenger air bag may deploy in
a collision. Also the front passenger
air bag status light may not illumi-
nate. See “Child restraints” (P.1-27)
for information about installing and
using child restraints.
. Confirm the operating condition
with the front passenger air bag
status light.
. If you notice that the front passen-
ger air bag status light is not
operating, it is recommended you
visit a NISSAN dealer to check the
occupant classification system.
. Until you have confirmed with your
dealer that your passenger seat
occupant classification system is
working properly, position the occu-
pants in the rear seating positions. This vehicle is equipped with the NISSAN
Advanced Air Bag System for the driver and
front passenger seats. This system is designed
to meet certification requirements under U.S.
regulations. It is also permitted in Canada.
All of
the information, cautions and warnings in
this manual apply and must be followed.
The driver supplemental front-impact air bag is
located in the center of the steering wheel. The
passenger supplemental front-impact air bag is
mounted in the instrument panel 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
operation.
The NISSAN Advanced Air Bag System has
dual stage air bag inflators. The system monitors
information from the Air bag Control Unit (ACU) ,
seat belt buckle sensors and the occupant
classification sensors (weight sensors) . Inflator
operation is based on the severity of a collision
and seat belt usage for the driver. For the front
passenger, the occupant classification sensors
are also monitored. Based on information from
the sensors, only one front air bag may inflate in
a crash, depending on the crash severity and

whether the front occupants are belted or
unbelted. Additionally, the front passenger air
bag may be automatically turned OFF under
some conditions, depending on the information
provided by the occupant classification sensors.
If the front passenger air bag is OFF, the front
passenger air bag status light will be illuminated
(if the seat is unoccupied, the light will not be
illuminated, but the air bag will be off) . (See
“Front passenger air bag and status light” (P.1-
55) for further details.) One front air bag inflating
does not indicate improper performance of the
system.
If you have any questions about your air bag
system, it is recommended you visit a NISSAN
dealer to obtain information about the system. If
you are considering modification of your vehicle
due to a disability, you may also contact
NISSAN. Contact information is contained in
the front of this Owner’s Manual.
When a front air bag inflates, a fairly loud noise
may be heard, followed by release of smoke.
This smoke is not harmful and does not indicate
a fire. Care should be taken not to inhale it, as it
may cause irritation and choking. Those with a
history of a breathing condition should get fresh
air promptly.
Front air bags, along with the use of seat belts,
help to cushion the impact force on the headand chest of the front occupants. They can help
save lives and reduce serious injuries. However,
an inflating front air bag may cause facial
abrasions or other injuries. Front air bags do
not provide restraint to the lower body.
Even with NISSAN advanced air bags, seat
belts should be correctly worn and the driver
and passenger seated upright as far as practical
away from the steering wheel or instrument
panel. The front air bags inflate quickly in order
to help protect the front occupants. Because of
this, the force of the front air bag inflating can
increase the risk of injury if the occupant is too
close to, or is against, the air bag module during
inflation.
The front air bags deflate quickly after a collision.
The front air bags operate only when the
ignition switch is in the ON position.
After pushing the ignition switch to the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7
seconds if the system is operational.

The front passenger air bag is designed
to automatically turn OFF under some
conditions. Read this section carefully
to learn how it operates. Proper use of
the seat, seat belt and child restraints is
necessary for most effective protection.
Failure to follow all instructions in this
manual concerning the use of seats,

Status light:
The front passenger seat is equipped with
occupant classification sensors (weight sen-
sors) that turn the front passenger air bag on or
off depending on the weight applied to the front
passenger seat.
The status of the front passenger 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
illuminates for about 7 seconds and then turns
off or illuminates depending on the front
passenger seat occupied status. The light
operates as follows:
The light operates as follows:
. Unoccupied passenger seat: The
light
is OFF and the front passenger 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 illuminates to
indicate that the front passenger air bag is
OFF and will not inflate in a crash. .
Occupied passenger seat and the passen-
ger meets the conditions outlined in this
section: The
light is OFF to indicate that
the front passenger air bag is operational.
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” (P.1-57) and “Troubleshoot-
ing” (P.1-58) in this section.
Front passenger air bag:
The front passenger air bag is designed to
automatically turn OFF when the vehicle is
operated under some conditions as described
below as permitted by 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
automatically turned OFF.
The occupant classification sensors (weight
sensors) are on the seat cushion frame under
the front passenger seat and are designed to detect an occupant and objects on the seat. For
example, if a child is in the front passenger seat,
the Advanced Air Bag System is designed to
turn the passenger air bag OFF in accordance
with the regulations. Also, if a child restraint of
the type specified in the regulations is on the
seat, the occupant classification sensors can
detect it 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
passenger air bag to be automatically turned
OFF. For small adults it may be turned OFF,
however, if the occupant does not sit in the seat
properly (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 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 chil-
dren be properly restrained in a rear seat.
NISSAN also recommends that appropriate
child restraints and booster seats be properly
installed in a rear seat. If this is not possible, the
occupant classification sensors are designed to
operate as described above to turn the front
passenger air bag OFF for specified child
restraints. Failing to properly secure child

restrains and to use the ALR mode may allow
the restraint to tip or move in an accident or
sudden stop. This can also result in the
passenger air bag inflating in a crash instead
of being OFF. (See “Child restraints” (P.1-27)
for proper use and installation.)
If the front passenger seat is not occupied, the
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 being detected by the occupant
classification sensors. 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 passenger seat is unoccupied.
If an adult occupant is in the seat but the front
passenger air bag status light is illuminated
(indicating that the air bag is OFF) , it could be
that the person is a small adult, or is not sitting
on the seat properly.
If a child restraint must be used in the front seat,
the front passenger air bag status light may ormay not be illuminated, depending 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 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 installed
properly, the seat belt is used properly and the
occupant is positioned properly. 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, the system may be sensing
an unoccupied seat (in which case the air bag is
OFF) . Your NISSAN dealer can check that the
system is OFF by using a special tool. However,
until you have confirmed with your 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 the
front passenger air bag status light will take a
few seconds to register a change in the
passenger seat status. However, if the seat
becomes unoccupied, the front passenger air
bag status light will remain off.
If a malfunction occurs in the front passenger air
bag system, the supplemental air bag warning
light, located in the meter and gauges area
will blink. Have the system checked. It is
recommended 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 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.
Safety — Seats, seat belts and supplemental restraint system1-57

1-58Safety — Seats, seat belts and supplemental restraint system
Steps:
1. Adjust the seat as outlined. (See “Seats”(P.1-2) .) Sit upright, leaning against the
seatback, and centered 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. (See “Seat belts” (P.1-15) .)
4. Remain in this position for 30 seconds allowing the system to classify 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 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 the front passenger seat
occupant 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 9.1 lbs. (4 kg)
hanging 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 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 front
passenger air bag status light is functioning
as intended. The front passenger air bag is
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 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.
