PRECAUTIONS ON
SUPPLEMENTAL RESTRAINT
SYSTEM
This Supplemental Restraint System (SRS) sec-
tion contains important information concerning
the driver and passenger supplemental front air
bags (NISSAN Advanced Air Bag System) ,
supplemental side air bags, curtain side-impact
air bags and pre-tensioner seat belts.
Supplemental front impact air bag system:
The NISSAN advanced air bag system can help
cushion the impact force to the head and chest of
the driver and front passenger in certain frontal
collisions.
Supplemental side-impact air bag system:
This system can help cushion the impact force to
the chest and pelvic area of the driver and front
passenger in certain side impact collisions. The
front seat side-impact supplemental side air bags
are designed to inflate on the side where the
vehicle is impacted.
Supplemental curtain side-impact air bag
system:This system can help cushion the im-
pact force to the head of occupants in front and
rear outboard seating positions in certain side
impact collisions. The curtain side-impact air
bags are designed to inflate on the side where
the vehicle is impacted.

These supplemental restraint systems are de-
signed tosupplementthe crash protection pro-
vided by the driver and front passenger seat belts
and arenot a substitutefor them. Seat belts
should always be correctly worn and the occu-
pant seated a suitable distance away from the
steering wheel, instrument panel and door finish-
ers. (See “Seat belts” earlier in this section for
instructions and precautions on seat belt usage.)
The supplemental air bags operate only
when the ignition switch is in the ON or
START position.
After turning the ignition key 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.
WARNING
cThe supplemental front air bags ordi-
narily will not inflate in the event of a
side impact, rear impact, rollover, or
lower severity frontal collision. Always
wear your seat belts to help reduce the
risk or severity of injury in various kinds
of accidents.
cThe front passenger air bag will not
inflate if the passenger air bag status
light is lit or if the front passenger seat
is unoccupied. See “Front passenger air
bag and status light” later in this
section.cThe seat belts and the supplemental
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 Ad-
vanced Air Bag System, if you are unre-
strained, leaning forward, sitting side-
ways or out of position 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 supplemental
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 use the seat belts.
cThe 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 us-
age then inflates the air bags. Failure to
properly wear seat belts can increase
the risk or severity of injury in an
accident.
cThe front passenger seat is equipped
with an occupant classification sensor
(pressure sensor) that turns 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 acci-
dent. See “Front Passenger air bag and
status light” later in this section.
cKeep 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
supplemental front air bag inflates.

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.
The driver supplemental front air bag is located in
the center of the steering wheel. The passenger
supplemental front air bag is mounted in the
dashboard above the glove box. The supplemen-
tal 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 supplemental front air bag
system operation.
The NISSAN advanced air bag system has dual
stage inflators. It also monitors information from
the crash zone sensor, the diagnosis sensor unit,
seat belt buckle sensors, occupant classification
sensor (pressure sensor) and passenger 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 informa-
tion 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 de-
tected on the passenger seat and how the seat
belt is used. If the front passenger air bag is OFF,
the passenger air bag status light will be illumi-
nated (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 supplemental 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 chok-
ing. Those with a history of a breathing condition
should get fresh air promptly.
Supplemental 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
supplemental 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 supplemental front air bags operate
only when the ignition switch is in the ON
or START position.
After turning the ignition key 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.
Front passenger air bag and status light
WARNING
The front passenger air bag is designed to
automatically turn OFF under some con-
ditions. Read this section carefully to
learn how it operates. Proper use of the
seat, seat belt and child restraints is nec-
essary for most effective protection. Fail-
ure to follow all instructions in this
manual concerning the use of seats, seat
belts and child restraints can increase the
risk or severity of injury in an accident.Status light

cOccupied passenger seat and the passen-
ger meet the conditions outlined in this sec-
tion: The light
oris OFF to in-
dicate 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 mode (child restraint
mode) . Based on the weight on the seat detected
by the occupant classification sensor and the belt
tension detected on the seat belt, the advanced
air bag system determines whether the front pas-
senger 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 automatic
locking mode (child restraint mode) , this could
cause the air bag to be turned OFF. Always be
sure to be seated and wearing the seat beltproperly 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 to
use the automatic locking mode (child restraint
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” 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 not
be 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.
If a malfunction occurs in the front passenger air
bag system, the supplemental air bag warning
light
, located in the meter and gauges area
in the center of the instrument panel, will blink.
Have the system checked by a NISSAN dealer.
Other supplemental front air bag precau-
tions
WARNING
cDo not place any objects on the steer-
ing wheel pad or on the instrument
panel. Also, do not place any objects
between any occupant and the steering
wheel or instrument panel. Such ob-
jects may become dangerous projec-
tiles and cause injury if the supplemen-
tal front air bag inflates.cImmediately after inflation, several
front air bag system components will be
hot. Do not touch them; you may se-
verely burn yourself.
cNo 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.
cDo not make unauthorized changes to
your vehicle’s electrical system, sus-
pension system or front end structure.
This could affect proper operation of
the supplemental front air bag system.
cTampering with the supplemental 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.

to those of a higher severity side impact. They are
designed to inflate on the side where the vehicle
is impacted. They may not inflate in certain side
collisions.
Vehicle damage (or lack of it) is not always an
indication of proper supplemental side air bag
and curtain side-impact air bag operation.
When the supplemental side air bag and curtain
side-impact air bag 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 condition should get fresh air
promptly.
Supplemental side air bags, along with the use of
seat belts, help to cushion the impact force on
the chest of the front occupants. Curtain side-
impact air bags help to cushion the impact force
to the head of occupants in the front and rear
outboard seating positions. They can help save
lives and reduce serious injuries. However, an
inflating side air bag and curtain side-impact air
bag may cause abrasions or other injuries.
Supplemental side air bags and curtain side-
impact 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 supplemental 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
side-impact air bag inflate quickly in order to help
protect the front and rear outboard occupants.
Because of this, the force of the side air bag and
curtain side-impact 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 and curtain side-impact air bag
will deflate quickly after the collision is over.
The supplemental side air bags and curtain
side-impact air bags operate only when the
ignition switch is in the ON or START posi-
tions.
After turning the ignition key 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.WARNING
cDo 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 the supplemental side air
bag inflates.
cRight after inflation, several side air bag
and curtain side-impact air bag system
components will be hot. Do not touch
them; you may severely burn yourself.
cNo unauthorized changes should be
made to any components or wiring of
the side air bag and curtain side-impact
air bag system. This is to prevent acci-
dental inflation of the side air bag and
curtain side-impact air bag or damage
to the side air bag and curtain side-
impact air bag system.
cDo not make unauthorized changes to
your vehicle’s electrical system, sus-
pension system or side panel. This
could affect proper operation of the
supplemental side air bag and curtain
side-impact air bag system.

cause irritation and choking. Those with a history
of a breathing condition should get fresh air
promptly.
After the pre-tensioner seat belts have activated,
load limiters allow the seat belt to release web-
bing (if necessary) to reduce forces against the
chest.
If any abnormality occurs in the pre-tensioner
system, the supplemental air bag warning
light
will not come on, will flash intermit-
tently or will turn on for 7 seconds and remain on
after the ignition key has been turned to the ON or
START position. In this case, the pre-tensioner
seat belt may not function properly. They must be
checked and repaired. Take your vehicle to the
nearest NISSAN dealer.
When selling your vehicle, we request that you
inform the buyer about the pre-tensioner seat belt
system and guide the buyer to the appropriate
sections in this Owner’s Manual.

When the ignition key is in the ON or START
position, the supplemental air bag warning light
illuminates for about 7 seconds and then turns
off. This means the system is operational.
If any of the following conditions occur, the
supplemental front air bag, supplemental side air
bag and curtain side-impact air bag and pre-
tensioner seat belt systems need servicing:
cThe supplemental air bag warning light re-
mains on after approximately 7 seconds.
cThe supplemental air bag warning light
flashes intermittently.
cThe supplemental air bag warning light does
not come on at all.
Under these conditions, the supplemental front
air bag, supplemental side air bags and curtain
side-impact air bag or pre-tensioner seat belt
systems may not operate properly. It 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 supplemental
front air bag, supplemental side air bag,
curtain side-impact air bag systems
and/or pre-tensioner seat belt systems
will not operate in an accident. 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 supplemental front air bags, supplemental
side air bags, curtain side-impact air bags and
pre-tensioner seat belts 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 oc-
curred. Repair and replacement of these supple-
mental air bag systems should be done only by a
NISSAN dealer.
When maintenance work is required on the ve-
hicle, the supplemental front air bags, supple-
mental side air bags, curtain side-impact air
bags, pre-tensioner seat belts and related parts
should be pointed out to the person performing
the maintenance. The ignition key should always
be in the LOCK position when working under the
hood or inside the vehicle.
WARNING
cOnce a supplemental front air bag,
supplemental side air bag or curtain
side-impact air bag has inflated, the air
bag module will not function again and
must be replaced. Additionally, if any of
the supplemental front air bags inflate,
the activated pre-tensioner seat belts
must also be replaced. The air bag mod-
ule and pre-tensioner seat belt system
should be replaced by a NISSAN dealer.
The air bag module and pre-tensioner
seat belt system cannot be repaired.
cThe supplemental front air bag, side air
bag and curtain side-impact air bag sys-
tems, and the pre-tensioner seat belt
system should be inspected by a
NISSAN dealer if there is any damage to
the front end or side portion of the
vehicle.
cIf you need to dispose of the supple-
mental air bag, pre-tensioner seat belt
system or scrap the vehicle, contact a
NISSAN dealer. Correct supplemental
air bag and pre-tensioner seat belt sys-
tem disposal procedures are set forth in
the appropriate NISSAN Service
Manual. Incorrect disposal procedures
could cause personal injury.
