The NISSAN Advanced Air Bag System moni-
tors information from the crash zone sensor,
the Air bag Control Unit (ACU), seat belt
buckle sensors and occupation classifica-
tion sensor (weight sensor). Inflator opera-
tion is based on the severity of a collision and
seat belt usage for the driver. For the front
passenger, the occupant classification sen-
sor is also monitored. Based on information
from the sensor, 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 and front passenger
supplemental knee air bag may be auto-
matically 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 and
front passenger supplemental knee air bag
are OFF, the front passenger air bag status
light will be illuminated. For additional infor-
mation, see “Front passenger air bag and
status light” (P. 1-54). One front air bag inflat-
ing does not indicate improper performance
of the system.
If you have any questions about your air
bag system, it is recommended that you
visit a NISSAN dealer to obtain information
about the system. If you are considering
modification of your vehicle due to a dis-ability, you may also contact NISSAN. Con-
tact 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 the re-
lease of smoke. This smoke is not harmful
and does not indicate a fire. Care should be
taken to not inhale it, as it may cause irrita-
tion 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 face and chest of the front occupants.
They can help save lives and reduce seri-
ous injuries. However, an inflating front air
bag may cause facial abrasions or other
injuries. Front air bags do not provide re-
straint to the lower body.
Even with NISSAN Advanced Air Bags, seat
belts should be correctly worn and the
driver and front 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 in-
crease the risk of injury if the occupant is
too close to, or is against, the front air bag
module during inflation.
The front air bags deflate quickly af ter a
collision.
The front air bags operate only when the
ignition switch is in the ON position.
Af ter placing the ignition switch in the
ON position, the supplemental air bag
warning light illuminates. The supple-
mental air bag warning light will turn off
af ter about 7 seconds if the system is
operational.

Front passenger air bag and status
light
WARNING
The front passenger air bag and front
passenger supplemental knee air bag
are designed to automatically turn OFF
under some conditions. Read this sec-
tion 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, seat belts, and child
restraints can increase the risk or se-
verity of injury in an accident. Status light
The front passenger seat is equipped with
an occupant classification sensor (weight
sensor) that turns the front passenger air
bag and front passenger supplemental
knee air bag on or off depending on the
weight applied to the front passenger seat.
The status of the front passenger air bag
and front passenger supplemental knee
air bag (ON or OFF) is indicated by the front
passenger air bag status light
which
is located on the instrument panel.
Af ter the ignition switch is placed in the
"ON" position, the front passenger air bag
status light on the instrument panel illumi-
nates for about 7 seconds and then turns
off or remains illuminated depending on
the front passenger seat occupied status.
The light operates as follows:
CONDITION DESCRIPTION PASSENGER AIR BAG
STATUS LIGHT () FRONT PASSENGER AIR BAG AND FRONT PASSENGER
SUPPLEMENTAL KNEE AIR BAG STATUS
Empty Empty front passenger seat ON (illuminated) INHIBITED
Nobody/Somebody Bag or Child or Child Restraint or
Small Adult in front passenger seat ON (illuminated)
INHIBITED
Adult Adult in the front passenger seat OFF (dark) ACTIVATED
In addition to the above, certain objects
placed on the front passenger seat may
also cause the light to operate as de-
scribed above depending on their weight.For additional information, see “Normal op-
eration” (P. 1-56) and “Troubleshooting”
(P. 1-57).
WRS0475
1-54Safety-Seats, seat belts and supplemental restraint system

Front passenger air bag
The front passenger air bag and front pas-
senger supplemental knee air bag are de-
signed to automatically 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
and front passenger supplemental 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. 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 and front pas-
senger supplemental knee air bag OFF in
accordance with the regulations. Also, if a
child restraint of the type specified in the
regulations is on the seat, its weight andthe 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, see “Child restraints” (P. 1-22).
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.
Safety-Seats, seat belts and supplemental restraint system1-55

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 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 cancheck 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. 1-11) 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 secondsallowing 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 occupyingthe front passenger seat:
•
Occupant is a small adult — the air bag light
is functioning as intended. The front pas-
senger air bag and front passenger supple-
mental 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.
Safety-Seats, seat belts and supplemental restraint system1-57

•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).
• 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 dealer for work on and
around the front air bag system. It is
also recommended that you visit a
NISSAN dealer for installation of elec-
trical equipment. The Supplemental
Restraint System (SRS) wiring har-
nesses* should not be modified or
disconnected. Unauthorized electri-
cal test equipment and probing de-
vices 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.

is located on the driver's side of the vehicle.
CAUTION
• If the vehicle runs out of fuel, the
Malfunction Indicator Light (MIL) may
come on. Refuel as soon as possible.
Af ter a few driving trips, the
light
should turn off. If the light remains on
af ter a few driving trips, have the ve-
hicle inspected. It is recommended
that you visit a NISSAN dealer for this
service.
• For additional information, see “Mal-
function Indicator Light (MIL)”
(P. 2-13).
DISTANCE TO EMPTY (DTE)
Displays the estimated distance the ve-
hicle can be driven before refueling. The
value is calculated based on recent fuel
economy, the amount of fuel remaining in
the fuel tank, and the actual fuel
consumption.
Changes in driving patterns or conditions
can cause the DTE value to vary. As a result,
the value displayed may differ from the ac-
tual distance that can be driven.
DTE display will change to “---” when the
fuel level in the tank is getting low, prior to
the fuel gauge reaching 0 (Empty).
NOTE:
• The DTE value af ter refill is estimated based on recent fuel economy and
amount of fuel added.
• If a small amount of fuel is added, or the ignition is on during refueling, the
display may not be updated.
• Conditions that affect the fuel economy will also affect the estimated
DTE value (city/highway driving, idle
time, remote start time, terrain, sea-
sonal weather, added vehicle weight,
added deflectors, roof racks, etc.).
