NISSAN Advanced Air Bag System
(front seats)
This vehicle is equipped with the NISSAN Ad-
vanced Air Bag System for the driver and front
passenger seats. This system is designed to
meet certification requirements under U.S. regu-
lations. It is also permitted in Canada. However,
all of the information, cautions, and warn-
ings in this manual still apply and must be
followed.
WRS0871
1-52Safety—Seats, seat belts and supplemental restraint system

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 dashboard above the glove box.
The front air bags are designed to inflate in higher
severity frontal collisions, although they may in-
flate 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 system opera-
tion.
The NISSAN Advanced Air Bag System has dual
stage inflators. It also monitors information from
the crash zone sensor, the Air bag Control Unit
(ACU) , seat belt buckle sensors, occupant clas-
sification sensor (pressure sensor) and passen-
ger seat belt tension sensor. Inflator operation is
based on the severity of a collision and seat belt
usage for the driver. For the front passenger, it
additionally monitors the weight of an occupant
or object on the seat and seat belt tension. 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
weight detected on the passenger seat and how
the seat belt is used. If the front passenger air bagis OFF, the 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” later in
this section 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, please contact NISSAN or your NISSAN
dealer. 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 the release 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 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 face and
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 pas-
senger 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 front 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 or START posi-
tion.
After placing the ignition switch in the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7 sec-
onds if the system is operational.

Front passenger air bag and status light
WARNING
The front passenger air bag is designed to
automatically turn OFF under some condi-
tions. 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 con-
cerning the use of seats, seat belts and
child restraints can increase the risk or
severity of injury in an accident.Status light
The front passenger air bag status light
is
located near the climate controls. After the igni-
tion switch is placed in the ONposition, the
front passenger air bag status light on the instru-
ment panel illuminates for about 7 seconds and
then turns off or remains illuminated depending
on the front passenger seat occupied status. The
light operates as follows:
● Unoccupied passenger’s seat: The
is
OFF and the front passenger air bag is OFF
and will not inflate in a crash.
● Passenger’s seat occupied by a small adult,
child or child restraint as outlined in this
section: The
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 meet the conditions outlined in this sec-
tion: The light
is OFF to indicate that
the front passenger air bag is operational.
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. Certain sensors are used to
meet the requirements.
One sensor used is the occupant classification
sensor (pressure sensor) . It is in the bottom of the
front passenger seat cushion and is designed to
detect an occupant and objects on the seat by
weight. It works together with seat belt sensors
described later. For example, if a child is in the
front passenger seat, the Advanced Air Bag Sys-
tem 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 regula-
tions is on the seat, its weight and the child’s
weight can be detected and cause the air bag to
turn OFF. Occupant classification sensor opera-
tion can vary depending on the front passenger
seat belt sensors.
The front passenger seat belt sensors are de-
signed to detect if the seat belt is buckled and the
amount of tension on the seat belt, such as when
it is in the Automatic Locking Retractor (ALR)
mode (child restraint mode) . Based on the
weight on the seat detected by the occupant
WRS0475
1-54Safety—Seats, seat belts and supplemental restraint system

classification sensor and the belt tension de-
tected on the seat belt, the Advanced Air Bag
System determines whether the front passenger
air bag should be automatically turned OFF as
required by the regulations.
Front passenger seat adult occupants who are
properly seated and using the seat belt as out-
lined in this manual should not cause the passen-
ger 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 cush-
ion (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. In addition, if the occupant
improperly uses the seat belt in the ALR mode,
this could cause the air bag to be turned 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 sensor and seat belt sensors are
designed to operate as described above to turn
the front passenger air bag OFF for specified
child restraints as required by the regulations.
Failing to properly secure child restraints and touse 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 re-
straints” earlier in this section 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’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 passenger air bag status light, you can
monitor when the front passenger air bag is au-
tomatically 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 passen-
ger 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 or not using the seat belt properly.
If a child restraint must be used in the front seat,
the passenger air bag status light may or may notbe illuminated, depending on the size of the child
and the type of child restraint being used. If the 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 air
bag status light is not illuminated, reposition the
occupant or child restraint in a rear seat.
If the passenger air bag status light will not illu-
minate 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 air bag system and passenger air bag status
light will take a few seconds to register a change
in the passenger seat status. For example, if a
large adult who is sitting in the front passenger
seat exits the vehicle, the 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.
Safety—Seats, seat belts and supplemental restraint system1-55

If a malfunction occurs in the front passenger air
bag system, the supplemental air bag warning
light
, located in the meters and gauges
area of the instrument panel, will blink. Have the
system checked by a NISSAN dealer.
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.
● Modifying or tampering with the front
passenger seat may result in serious
personal injury. For example, do not
change the front seats by placing mate-
rial on the seat cushion or by installing
additional trim material, such as seat
covers, on the seat that are not specifi-
cally designed to assure proper air bag
operation. Additionally, do not stow any
objects under the front passenger seat
or the seat cushion and seatback. Such
objects may interfere with the proper
operation of the occupant classification
sensor (pressure sensor) . ●
No unauthorized changes should be
made to any components or wiring of
the seat belt system. This may affect the
front air bag system. Tampering with
the seat belt system may result in seri-
ous personal injury.
● Work on and around the front air bag
system should be done by a NISSAN
dealer. Installation of electrical equip-
ment should also be done by a NISSAN
dealer. The Supplemental Restraint
System (SRS) wiring should not be
modified or disconnected. Unauthor-
ized electrical test equipment and prob-
ing devices should not be used on the
air bag system.
● A cracked windshield should be re-
placed immediately by a qualified repair
facility. A cracked windshield could af-
fect 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.
1-56Safety—Seats, seat belts and supplemental restraint system

Front seat-mounted side-impact
supplemental air bag and roof-
mounted curtain side-impact and
rollover supplemental air bag systems
The side air bags are located in the outside of the
seatback of the front seats. The curtain air bags
are located in the side roof rails.All of the
information, cautions, and warnings in this
manual apply and must be followed. The
side air bags and curtain air bags are designed to
inflate in higher severity side collisions, although
they may inflate if the forces in another type of
collision are similar to those of a higher severity
impact. They are designed to inflate on the side where the vehicle is impacted. They may not
inflate in certain side collisions.
Curtain air bags are also designed to inflate in
certain types of rollover collisions or near roll-
overs. As a result, certain vehicle movements (for
example, during severe off roading) may cause
the curtain air bags to inflate.
Vehicle damage (or lack of it) is not always an
indication of proper side air bag and curtain air
bag operation.
When the side air bags and curtain air bags
inflate, 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 con-
dition should get fresh air promptly.
Side air bags, along with the use of seat belts,
help to cushion the impact force on the chest of
the front occupants. Curtain air bags help to
cushion the impact force to the head of occu-
pants in the front and rear outboard seating po-
sitions. They can help save lives and reduce
serious injuries. However, an inflating side air bag
or curtain air bag may cause abrasions or other
injuries. Side air bags and curtain air bags do not
provide restraint to the lower body.
The seat belts should be correctly worn and the
driver and passenger seated upright as far as
practical away from the side air bag. Rear seat
passengers should be seated as far away as
practical from the door finishers and side roof
rails. The side air bags and curtain air bags inflate
quickly in order to help protect the occupants.
Because of this, the force of the side air bag and
curtain air bag inflating can increase the risk of
injury if the occupant is too close to, or is against,
these air bag modules during inflation. The side
air bag will deflate quickly after the collision is
over.
The curtain air bags will remain inflated for a short
time.
The side air bags and curtain air bags op-
erate only when the ignition switch is in the
ON or START position.
After placing the ignition switch in the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7 sec-
onds if the system is operational.

WARNING
●Do not place any objects near the seat-
back of the front seats. Also, do not
place any objects (an umbrella, bag,
etc.) between the front door finisher
and the front seat. Such objects may
become dangerous projectiles and
cause injury if a side air bag inflates.
● Right after inflation, several side air bag
and curtain 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 side air bag and curtain air bag
systems. This is to prevent damage to or
accidental inflation of the side air bag
and curtain air bag systems.
● Do not make unauthorized changes to
your vehicle’s electrical system, sus-
pension system or side panel. This
could affect proper operation of the cur-
tain air bag systems. ●
Tampering with the side air bag system
may result in serious personal injury.
For example, do not change the front
seats by placing material near the seat-
backs or by installing additional trim
material, such as seat covers, around
the side air bag.
● Work around and on the side air bag
and curtain air bag systems should be
done by a NISSAN dealer. Installation
of electrical equipment should also be
done by a NISSAN dealer. The SRS wir-
ing harnesses* should not be modified
or disconnected. Unauthorized electri-
cal test equipment and probing devices
should not be used on the side air bag
or curtain air bag systems.
* The SRS wiring harness or connectors are
yellow or orange for easy identification.
When selling your vehicle, we request that you
inform the buyer about the side air bag and
curtain air bag systems and guide the buyer to
the appropriate sections in this Owner’s Manual.
Seat belts with pretensioners (Front
seats)
WARNING
● The pretensioners cannot be reused af-
ter activation. They must be replaced
together with the retractor and buckle
as a unit.
● If the vehicle becomes involved in a
collision but a pretensioner is not acti-
vated, be sure to have the pretensioner
system checked and, if necessary, re-
placed by your NISSAN dealer.
● No unauthorized changes should be
made to any components or wiring of
the pretensioner system. This is to pre-
vent damage to or accidental activation
of the pretensioners. Tampering with
the pretensioner system may result in
serious personal injury.
● Work around and on the pretensioner
system should be done by a NISSAN
dealer. Installation of electrical equip-
ment should also be done by a NISSAN
dealer. Unauthorized electrical test
equipment and probing devices should
not be used on the pretensioner system.
1-58Safety—Seats, seat belts and supplemental restraint system

●If you need to dispose of a pretensioner
or scrap the vehicle, contact a NISSAN
dealer. Incorrect disposal procedures
could cause personal injury.
The pretensioner system may activate with the
supplemental air bag system in certain types of
collisions. Working with the seat belt retractor,
the pretensioner helps tighten the seat belt when
the vehicle becomes involved in certain types of
collisions, helping to restrain front seat occu-
pants.
The pretensioner is encased with the seat belt
retractor. These seat belts are used the same way
as conventional seat belts.
When a pretensioner activates, smoke is re-
leased and a loud noise may be heard. 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.
After pretensioner activation, load limiters allow
the seat belt to release webbing (if necessary) to
reduce forces against the chest. The supplemental air bag warning lightis
used to indicate malfunctions in the pretensioner
system. (See SUPPLEMENTAL AIR BAG
WARNING LIGHT in this section for more de-
tails.) If the operation of the supplemental air bag
warning light indicates there is a malfunction,
have the system checked by a NISSAN dealer.
When selling your vehicle, we request that you
inform the buyer about the pretensioner system
and guide the buyer to the appropriate sections
in this Owner’s Manual.

SUPPLEMENTAL AIR BAG
WARNING LIGHT
The supplemental air bag warning light,
displaying
in the instrument panel, moni-
tors the circuits for the air bag systems, preten-
sioners and all related wiring.
When the ignition switch is placed in the ON or
START position, the supplemental air bag warn-
ing light illuminates for about 7 seconds and then
turns off. This means the system is operational. If any of the following conditions occur, the front
air bag, side air bag, curtain air bag and preten-
sioner systems need servicing:
● The supplemental air bag warning light re-
mains on after approximately 7 seconds.
● The supplemental air bag warning light
flashes intermittently.
● The supplemental air bag warning light does
not come on at all.
Under these conditions, the front air bag, side air
bag, curtain air bag or pretensioner systems may
not operate properly. They must be checked and
repaired. Take your vehicle to the nearest
NISSAN dealer.
WARNING
If the supplemental air bag warning light
is on, it could mean that the front air bag,
side air bag, curtain air bag and/or preten-
sioner systems will not operate in an acci-
dent. To help avoid injury to yourself or
others, have your vehicle checked by a
NISSAN dealer as soon as possible.
Repair and replacement procedure
The front air bags, side air bags, curtain air bags
and pretensioners are designed to inflate on a
one-time-only basis. As a reminder, unless it is
damaged, the supplemental air bag warning light
remains illuminated after inflation has occurred.
Repair and replacement of these supplemental
air bag systems should be done only by a
NISSAN dealer.
When maintenance work is required on the ve-
hicle, the front air bags, side air bags, curtain air
bags, pretensioners and related parts should be
pointed out to the person performing the mainte-
nance. The ignition switch should always be in
the LOCK position when working under the hood
or inside the vehicle.
